Easy 5-Minute Installation of the LTM-2

Thu, 20 Aug 2020 09:42:52 GMT

In 2014, Instek Control launched the Level Transmitter Mining (LTM-2) level measurement probe as alternative to traditional measurement systems for difficult and sometimes seemingly impossible measuring environments.

Just over six years later, the LTM-2 has become a highly popular measurement tool in the mining and pulp and paper industries.

Simple and fast installation

One of the major benefits of the LTM-2 has proven to be its easy installation process.

Installing the LTM-2 probe instead of ultrasonic equipment has the advantage of not being density dependent and is not sensitive to froth or product build-up. The probe can be installed within five minutes and requires low maintenance, thereby making it “virtually maintenance free” as there are no mechanical moving parts. When installed and utilised correctly, the LTM-2 probe will deliver on performance, creating a stable control environment for flotation applications.

A benchmark success

With setup that can be achieved in less than 5 minutes, the LTM-2 probe has been adopted with great success, especially in the mining industry. Besides easy installation, the LTM-2 provides the following advantages when installed in place of ultrasonic devices:

No moving parts
Not density dependent
Not sensitive to froth or product build-up
The probes are virtually maintenance free

The unit has proven to accurately measures the pulp/froth interface and provides a stable feedback signal at an optimal update rate without excessive ‘damping’, all of which provides improved process control and stability.

Setting higher standards leads to continuous improvement of performance.

Hygienic measurement technology is now hybrid and modular

Fri, 22 Nov 2019 09:02:52 GMT

Instek Control is pleased to introduce the ITM-51 – the first turbidity sensor with IO-Link developed by Anderson-Negele.

The ITM-51 turbidity sensor offers simultaneous access to digital and analog interfaces through IO-link technology. This means data can be transmitted digitally alongside 4...20 mA technology giving users the ability to switch from analog to digital network technology at any time – the best of both worlds. By combining IO-Link with the modular platform, a unique combination of hardware and software is created that is unmatched in flexibility, simplicity and system compatibility.

Proven industry standard for hygienic and aseptic applications in food, beverage and pharma

In times of rapid technology progress, IO-Link creates investment security. Digitisation, one of the key drives of Industry 4.0, has found its way into many branches of industry and, today, it’s impossible to imagine life without it. With IO-Link, you can reliably manage all aspects of process control and bring all measuring points, control devices, and operating elements into one dependable system. After extensive suitability testing, Anderson-Negele is using this technology as the data transfer standard in sanitary application across the food, beverage, and pharmaceutical industries.

From simple data transfer to intelligent communication

With IO-Link, data can be transmitted to the control center and back out to the sensor allowing individual sensors to be set, queried and checked at any time. This makes it possible to detect potential faults, signs of wear and risk of failure at an early stage. Maintenance work can be planned according to true need, and production downtimes can be minimised.

With its application-specific configuration, the modular sensor platform offers equipment that is tailored to meet your requirements, cost-optimised, and enables simple replacement of individual components (e.g., displays, electronics). The optional remote version features separate sensors and electronics housing. The electronics are identical for all sensor types and are recognised independently. This “Smart Replace Design” means each sensor can be replaced simply by plugging in the cable and one replacement unit of electronics housing and cable is enough for all sensors.

Salute Giovanni Venturi!

Tue, 05 Nov 2019 06:32:49 GMT

In this blog post we are going back in time to toast the life of Italian physicist Giovanni Battista Venturi (1764 – 1822). He was responsible for figuring out an important element in basic fluid and airflow dynamics, which came to be known as The Venturi Effect.

Simply put, the Venturi effect shows that when a fluid is forced through a pipe that has a smaller cross-section, the static pressure and flow velocity increases. When the fluid then moves into a pipe with a larger cross – section, there will be an immediate pressure drop, creating a vacuum. The decrease in flow velocity creates high turbulence.

The Venturi effect is applicable to a range of disciplines ranging from Aeronautics to Agriculture, and everything in between. In the industrial and scientific fields, Venturi tubes are often used to measure the flow rate of a fluid.

CO2 Injector for Food and Beverage Applications

Arguably, no one knows more about brewing beer than the Germans, therefore it is no surprise that 40-year old German company Centec GmbH, have used the Venturi principle to create what is known as the “best mixing system for carbonation and mixing of liquids to date.” Prosit Centec.

For the Food and Beverage Industry, Centec developed the Vortex Injector using the Venturi principle
The Centec Vortex Injector is especially designed for the homogeneous mixing of liquids and gas (e.g. CO2, O2 or N2) with beer, wine, or other beverages. Because this system is so effective the dissolving times are greatly reduced, and dosing can be done effectively, precisely and accurately.

Moving through the mixing chamber there is an immediate pressure drop that opens the liquid and creates a vacuum. This creates conditions for a near perfect fusion of liquids and or gases. The gas or liquid is injected into the product through multiple nozzles around the circumference of the mixing chamber. The homogenous mixing of the products take place instantaneously

this greatly reduces the size of a carbonation unit and adding carbon dioxide quickly and uniformly into beer, wine, beverages and sparkling water.

Best in the Business

The benefits of the Venturi Vortex Injector are numerous and include:

Instant, homogenous mixing and additive dosing of liquids and gasses
Application-specific design with the unique characteristics of each product and process incorporated
Full CIP Capability
Outstanding price-to-performance ratio
Smaller holding loops and dissolving times resulting in more compact plant designs
More accurate dosing ability resulting in material and time savings.

Instek builds reliable partnerships around the world, so we can be a reliable partner to your business. We are proud to be associated with Centec’s global reputation of high-quality process equipment and process sensors for the brewery, beverage, pharmaceutical and biotechnology industries.

Now available: Conductivity sensor with IO-Link

Fri, 18 Oct 2019 07:30:14 GMT

igitalisation has already found its way into many branches of industry under the keywords "Industry 4.0" or "Internet of Things", and today it is impossible to imagine life without it. INSTEK Control is excited to announce that the new dimension in hygienic measuring technology is digital and analogue, compact or remote and modular.

The new ILM-4 with IO-Link combines the best of two worlds, as the first in a series of hygienic sensors, equipped with both a digital and analog interface in parallel.

The (R)evolution of conductivity measurement

IO-Link offers significant advantages over analog technology when it comes to reliably controlling the entire process technology with a large number of measuring points, control and operating elements. It is comparable to a multi-lane, bidirectional data highway instead of a narrow one-way street.

NSet-up and installation are extremely time- and cost-saving. A three-pole standard cable, which does not even have to be specially shielded, is sufficient for the signal transmission and power supply itself. In practice, point-to-point connections are made at field level from various sensors to collection points, so-called IO-Link masters, and from there via fieldbus system to the control centre.

Simple data transfer becomes intelligent communication

With IO-Link, data streams in the opposite direction towards the sensors are now also possible. In this way, the status of the sensor can be checked and specifically queried at any time. This makes it possible to detect potential faults, signs of wear or an increased risk of failure at an early stage and helps to avoid production downtimes.

"Plug-and-play" takes on a whole new meaning

Sensor replacement with IO-Link becomes easier and safer than ever before and can be carried out independently, at any time and by any employee without any programming effort. The device configuration of each connected sensor can be stored in the IO-Link Master. Immediately when plugged in, the new sensor is automatically recognised, configured and parameterised by the IO-Link Master.

The combination of IO Link, modular platform, and intelligent software, creates a unique constellation of hardware and software that is unparalleled in flexibility, simplicity and system compatibility.

This sets the ILM-4 apart from all other conductivity sensors and will be a trusted workhorse for the user, continually satisfying the process requirements with a very accurate, fast and user friendly Platform

For more information on the ILM-4 with IO-Link, contact INSTEK Control to discuss your specific needs. We provide products to clients across sub-Sahara Africa.

Getting cleaning concentration, time and temperature right: your key to successful brewery sanitation

Thu, 03 Oct 2019 09:46:29 GMT

The global beverage industry is estimated to reach $1.9 trillion by 2020. According to BCC Research, the international fermented ingredients market, necessary for brewing, could grow to be worth $28.4 billion in the same year.

However, in the world of beverage production, brewing has the unique characteristic of requiring meticulous sanitation procedures to produce a high quality, drinkable beverage. When it comes to a brewery, you clean to prevent the transfer of tastes from one beer to the next, and you clean to help assure your product is safe for human consumption. In the face of increasing supply and demand, brewing plants are compelled to keep the cost of production as low as possible, without sacrificing safety and quality of the end-product.

One area that can drive costs up and affect product quality in the brewing and other beverage industries, is too high levels of cleaning agent concentrations in the tanks. Effective Cleaning-in-Place (CIP) cleaning relies on correct metering of the concentration of cleaning agent, contact time and solution temperature.

How does it work?

Understanding the processes and chemicals involved in the all-important work of cleaning and sanitising your brewery can help make your routine more efficient and effective.

During cleaning, the exact concentration of cleaning agent combined with the factors of time and temperature are decisive in running an effiecient process:

The right concentration of chemicals must be achieved. While low concentrations can lead to inadequate cleaning results, concentrations that are above the required level not only drive up costs, but can leave residual traces and also damage the equipment.
Time is how long is the cleaner in contact with the soil and the surface. Too short and the soil won't be removed. Too long and you are wasting energy and have excess downtime and run the risk of redepositing.
A C.I.P cycle must be run within the specified temperature range. If the solution becomes to cold downstream the process is ineffective and the expensive chemicals and time used for the process, is literally flushed down the drain.

Conductivity sensors for the safety and quality of your brew

Evidently, achieving the right combination of flow characteristics at a given temperature, time and concentration is crucial to fast and economical cleaning.

When you are on a tight schedule and budget, being able to minimise resources and maximise product reliability is always first prize. Anderson-Negele’s new, optimised ILM-4 conductivity sensor ensures that the correct levels are sustained and that they reduce the quantities of chemicals used. With a temperature response time that is four times faster than its predecessors, the ILM-4 conductivity sensor can also differentiate between wash and rinse cycles – producing further cost savings by reducing safety margins.

Benefits of getting the ILM-4 for your beverage plant

INSTEK Control is proud to provide the ILM-4 to our clients in the food and beverage industries in sub Saharan Africa. It has been described as the best of class in measurement accuracy. For the user, this means:

a reduction in the duration of the CIP process without impacting the required process quality;
inductive measurement of the specific conductivity of liquid media in the range of 0...999 mS/cm;
accurate temperature compensated measurement with a Pt 1000 embedded sensor
robust design with a stainless-steel body ensures many years of use and easy cleaning;
reliable process control with clear reduction of batch to batch contamination and extended product shelf life;
controlling of CIP processes (e. g. phase separation detergents/water);
concentration measurement (e.g. Alkali and acid concentration in remaking);
reduced lifetime cost due to modular sensor design with Smart Replace Technology; and
intensive and client-oriented support and service to guarantee maximum customer satisfaction.

The ILM-4 inductive conductivity sensor from Anderson-Negele is the continuation of the success story of the ILM series . The sensor has undergone systematic development to meet the demand for intelligent sensors for hygienic applications. The sensor is compatible with the predecessor models and easy to integrate in the process on account of its compact housing design.

All adjustments can be made quite simply on the device display or via a laptop and the calibration function allows calibrating by the plant operator on-site. In addition, any replacement of components can also be made on-site which saves maintenance costs and time.

Turning up the pressure for consumer product safety

Mon, 09 Sep 2019 06:48:14 GMT

The highest priority in the production of food, beverages and pharmaceuticals is product safety. In sanitary applications, such as the production of vaccines or baby food, the purity, quality and stability of the product must be ensured.

Critical, sanitary and sterile applications such as the food and beverage , dairy , brewery and life sciences industries demand hygienic design. A crucial element in these markets is the ability to indicate the pressure in manufacturing pipelines, fermenters or manufacturing facilities via easy-to-read pressure gauges. In addition, pressures and vacuums must be monitored constantly during cleaning, sterilisation and testing. This process reliability can be guaranteed by making the correct choice of hygienic pressure transmitter; ensuring you get accurate, repeatable results with no maintenance over extended periods.

Robust, needs-based, cost-effective

INSTEK Control cc, in conjunction with Anderson-Negele, offer our clients in sub-Saharan Africa an extensive range of sensors to make all fluid processing application efficient and reliable. Anderson-Negele’s new P41 temperature compensated pressure transmitter is robust, needs-based and cost-effective.

For many standard applications, a sensor which precisely measures the pressure and reliably transmits it to the PLC, is perfectly sufficient. The new P41 is an inexpensive, compact, temperature-compensated pressure sensor that offers the right solution for applications.

The P41 is designed to meet high process requirements, offering pressure ranges up to 40 bar, overpressure resistance up to 100 bar, and vacuum resistance. The measuring range can be individually adapted to the desired process pressures and a choice can be made between absolute and relative measuring cells. Compound measurement is also possible, which means the relative measuring cell can be used to measure the vacuum range. The P41 is also robust when it comes to temperatures: up to 125 °C as standard, up to 150 °C / 60 min for CIP/SIP cleaning, and even up to 250 °C permanently with optional cooling section. The entire sensor, including the diaphragm, is made of stainless steel for excellent cleanability and durability.

How do you like your viennas?

Fri, 23 Aug 2019 07:47:43 GMT

Safe? Uncontaminated? Quality tested?

Did you know to make viennas, the meat goes from grinder to mixer to being clipped for a casing and back into a mixer. After processing the viennas into either red or smoked, it goes into a spiral dryer to dry – increasing shelf life. From there it is chilled, packed and transferred into either a holding freezer or into the plant’s dispatch area and on to retail markets.

Taking just this one example, there are at least nine processes from factory to table. Which means there are at least nine points of production where things can go wrong, contaminating the product and becoming a deadly health and safety issue for consumers and a compliance nightmare for manufacturers.

Quality monitoring and analysis of meat products

In 2018/19, South African consumers spend the equivalent of $12.7 billion on meat products, representing about 30% of their total food expenditures. The preference for meat in South Africa has been rising in the last decade (USDA Foreign Agriculture Service) and is expected to continue surging.

The 2017/18 South African listeriosis outbreak resulting from contaminated processed meats focused a glaring spotlight on the whole industry. While the increase in the consumption of animal meat will create demand for more processed food, it will also result in increased pressure on manufacturers to ensure the quality of South African meat products; not only from a compliance viewpoint, but also consumer demand.

Manufacturers of meat and dairy products have become more conscious of the steps need to be controlled and monitored to obtain safe and high-quality products, including complying with stringent food safety hygiene and safety regulations, and engaging in Good Manufacturing Practices, Good Hygienic Practices and HACCP.

Quick, reliable monitoring tool for the food industry

In recent years, due to an increase in the consumer awareness regarding product quality and authenticity of food, rapid and effective quality control systems have been sought by meat and other food industries.

In response, INSTEK CONTROL has introduced MyLab, a rapid analysis device designed in Germany, to local food manufacturers.

Traditionally, the method used for food analysis of meat and meat products, yeasts and dairy products is to send samples of your products to a lab. The results take 8 to 10 days, usually too late to be useful for anything other than documentation purposes.

MyLab can measure raw materials, every product batch and all pre-packaged food in a matter of seconds, ensuring:

Incoming raw materials are exactly what you ordered
Standardisation of batches during the production process
Control of the finished products before dispatch

MyLab can be applied throughout the whole food production chain: from raw materials to intermediates to final products, from the inspection of incoming goods to hygiene monitoring and finally to product analysis for correct labelling.

How does it work?

MyLab uses Near-infrared (NIR) Spectroscopy – a fast and cost‐effective tool for estimating various meat quality parameters as well as detecting adulteration (making sure your raw material is what you ordered).

NIR spectroscopy provides many advantages when compared to traditional methods which includes speed of analysis, non-destructive and non-invasive measurement, little or no sample preparation, non-contact technique and several others. Just a few of MyLab’s advantages over classical wet-chemical and chromatographic analyses include being very fast, with analysis times below 30 seconds, as well as being cost-effective and safe, since no hazardous chemicals are used. Today it is widely used in the food industry and in biogas plants for non-destructive qualitative and quantitative analysis of raw materials, in-process materials, and finished products throughout the entire manufacturing process.

MyLab is available from INSTEK CONTROL. Contact us to discuss the benefits MyLab can bring to your plant.

WATER PRE-TREATMENT FOR THE BEVERAGE INDUSTRIES

marizelle@instek.co.za (Instek Control) — Wed, 21 Nov 2018 18:44:15 GMT

Raw water quality depends greatly on its source. Based on the raw water quality and the specifications for the purified water, Centec select the most appropriate technologies for each client. Usually, multi-stage regimes are necessary for water purification. For water pre-treatment, sand and multi media filters are used to remove suspended material (e. g. silt, clay, organic matter). Such material in water can reduce the effectiveness of downstream components such as ion exchange resins and reverse osmosis membranes. Soluble iron and manganese are found in water that contains no dissolved oxygen. They cause a metallic taste and form deposits in piping systems. The Centec De-Ironizer is designed for iron and manganese removal. If harmful bacteria and microbes are suspected, the water is disinfected by UV, ozone or free chlorine. Activated carbon (AC) filtration removes odours, tastes and oxidizing agents like free chlorine that can lead to chemical attack of membranes elements in subsequent purification steps.

Sand & Multi Media Filter

A sand filter only uses sand as filter medium. Whereas a multi media filter typically have 3 to 5 layers of different media types. Both are back-flushable. In a sand filter the smallest particles are trapped at the top of the media bed, while larger ones sink deeper proportional to their mass. The result is a very limited use of the media depth, because virtually all filterable particles are trapped at the very top of the filter bed. Multi media filters use several layers of different materials, each having a significantly different density. Due to the layering, larger particles are removed first at the top of the media bed, while smaller particles are trapped further below. Trapping particles in this manner, results in more effective removal of contaminants, even of very small turbidity forming particles. Furthermore, longer run times between backwash cycles are achieved.

De-Ironizer

Dissolved iron and manganese are removed from water by oxidation and subsequent filtration. Fe2+ is oxidized to Fe3+, which with oxygen, forms the insoluble iron complex Fe(OH)3. Mn2+ is oxidized to Mn4+, which with oxygen, forms insoluble MnO2. An ideal and low-cost method of providing oxidation is to use the oxygen in air as the oxidizing agent. For removal of the insoluble iron and manganese gravel can serve as filtration media. By cyclical back-flushing the iron and manganese particles are washed out and removed.

Activated Carbon Filter

Activated carbon filtration is a method of filtering that uses a bed of activated carbon to remove contaminants by chemical absorption. Due to the highly porous structure of activated carbon, each carbon particle provides an extremely large surface area. Contaminant molecules are trapped inside this structure. Activated carbon adsorbs organic substances which cause odours and tastes. Furthermore, it acts as a catalyst in contact with free chlorine supporting the reaction of free chlorine to harmless chloride ions.

Disinfection

Chlorine is an inexpensive treatment method for deactivating microorganisms like bacteria and viruses. Stored in pressurized containers, it can be injected as a gas directly into the water. Alternatively, a sodium hypochlorite solution can be used. This solution is easier to handle than chlorine gas. Disinfection can also be achieved with calcium hypochlorite, a solid disinfectant. This form can be stored as powders, granules or tablets. Ozone (O3) is another powerful oxidizing agent. It is pumped into water systems to kill biological contaminants like bacteria and viruses. Since ozone gas is very unstable, O3 needs to be created on site. Ozone is pure active oxygen and produces no residual odours or tastes in water. Also ultraviolet (UV) light can be used to kill harmful microorganisms. The UV process is an attractive option in many cases because it is chemical-free and investment costs are low.

The new ITM-51 turbidity sensor from Anderson-Negele is an advancement of the established ITM-3 sensor that brings with it greater flexibility for use in a wide range of applications, even better performance and a modular design. The new sensor opens opportunities for reducing the quantities of water, chemicals and energy used in the plant, optimizing product losses and increasing competitiveness.

The top applications of the ITM-51 turbidity sensor from Anderson-Negele are phase separation of products (for example, whey – cream – milk) simultaneously monitoring separator which is plant protection at the inlet and quality assurance at the outlet. Then there is CIP return flow (monitoring of the pre-rinse water for product remnants). For brewery industry ITM-51 turbidity sensor will check yeast harvest. The new sensor will ensure quality control at all levels as well as monitoring of filters and seals for wire breakage.

The ITM-51 is the compatible advancement of the popular and proven ITM-3 and offers wide range of applications like expanded measurement range, increased temperature and pressure ranges. In addition to this, it features comprehensive options for configuration and process integration on the basis of the modular sensor platform from Anderson-Negele. Another feature that makes this sensor different is it can be checked by users directly on location with the aid of an external test kit. It is reliable with wear-free LED and excels in terms of high reproducibility and rapid response time. The ITM-51 is flexible and based on modular structure with standardized components and numerous process connections. With its front-flush, hygienic design, the ITM-51 is easy to clean in automated CIP processes. The hygienic design of the sensor was checked and confirmed in EHEDG tests. The ITM-51 is a flexible turbidity sensor with numerous configuration options available at attractive conditions and therefore an ideal tool for process optimization with a rapid ROI.

The NEW D3 Differential Pressure and Level Transmitter

marizelle@instek.co.za (Instek Control) — Mon, 07 May 2018 19:05:43 GMT

The Anderson-Negele D3 Differential Pressure and Level Transmitter is the most complete electronic differential transmitter with best-in-class performance and dual mA output. It uses the proven state-of-the-art temperature compensation technology of L3 and significantly reduces the effects of process and ambient temperature changes.

The diff mA output can be scaled to volumetric values like gallons and lbs. and the second mA output can be used to monitor the top (head) pressure or the bottom (total system) pressure.

While the sensor comes ready for installation right out-of-the-box, the simple graphical interface makes field setup and programming very easy. The D3 transmitter display can be direct mounted to either of the two sensors or can be mounted remotely for easy access.

Range of applications

- Hydrostatic level measurement in environments with temperature fluctuations

- Differential pressure measurement in tanks up to 110°C (230°F)

- Hydrostatic level, volume and mass measurement in pressure vessels

Application examples

- Hygienic differential pressure and level monitoring for process in breweries, dairies and food and beverage industry

- Pressure drop measurement in diaphragms

Hygienic design/Process Connections

- Use of Negele weld-in sleeve EMZ-352 or build-in system EHG-…/1” results in a hygienic installation situation that is free of gaps and dead space and is easy to sterilize

- Conforming to 3-A Sanitary Standard 74-06 with DIRECTadapt

- CIP-/SIP-cleaning up to 130°C (266 °F) for 60 minutes max

- All material in contact with the product have FDA approval

- Sensors completely made of stainless steel

- Further process connections available through CLEANadapt

Measuring principal of the pressure sensor

In the D3 systems, each sensor uses an internal piezo-electric signal converter and a temperature sensor to measure the pressure and temperature of the capillary fill. The electrical signal of the pressure converter and the resistance of the temperature sensor are measured and converted to a compensated pressure value in the pressure fitting. Both signals are transferred digitally to the head. They are then output in a standardized 4…20mA and HART 7.0 signal for the differential pressure and in a 4…20mA signal for the top or total pressure.

The new D3 is your go-to transmitter for any level applications where pressure and/or vacuum conditions exist.

DeAlco Tec – Dealcoholization of beer

marizelle@instek.co.za (Instek Control) — Thu, 19 Apr 2018 18:58:30 GMT

The dealcoholization system DeAlcoTec applies an aroma conserving method to remove alcohol from beer after complete fermentation. Ingredients are conserved to a particularly high degree or added back to the beer. The dealcoholization temperature is low and it is possible and the residual alcohol content is close to the detection level.

For dealcoholization incoming alcohol rich product is first gently heated by a regenerative heat exchanger in counter current to the finished product. It is dispersed at the top of a specially designed evaporation column. For CO2 containing product, prior degassing prevents formation of foam. Exhaust vapours are fed into the bottom of the column. They rise upwards inside the column in counter current to the falling warm liquid. Thereby, they remove the volatile alcohol from the product. The less volatile components fall to the column base. They flow into the falling film evaporator that generates the exhaust vapour for delacoholization. Densely packed, thin stainless steel sheets in the column maximize the transfer surface and the contact time between the product and the exhaust vapours. The complete process takes place under vacuum. A key benefit of the Centec technology is the exceptionally effective alcohol removal at low temperature. The remaining alcohol-free product is pumped away and cooled for storage or further processing, e. g. for carbonation. The volatile flavours from the original product can be separated from the exhaust vapours in a special aroma recovery system and added back to enhance the taste of the finished product. If desired, the alcohol is concentrated to form liquid alcohol of up to 90 vol. % for use in other applications or for sale.

For highly precise measurement and control of critical product characteristics such as alcohol, O2 and CO2 content, Centec process sensors are ideally suited. Centec have decades of experience in the development and manufacturing of own precision instruments.

Clean-In-Place (CIP) check and optimization made easy

marizelle@instek.co.za (Instek Control) — Tue, 10 Apr 2018 19:03:53 GMT

Without an online, real-time bacteria detection device, able to monitor microbiological growth since its first phases, it is difficult to check if Clean-In-Place is really effective, or if it needs to be adjusted.

To limit bacterial growth on the internal surfaces of pipes and tanks (a phenomenon usually known as "biofilm" or "bacterial slime"), most industries apply Clean-In-Place (CIP). Such treatment entails the injection of chemicals in the process line, to remove both deposit (organic and inorganic fouling) and microorganisms (biofilm). Different formulations and approaches exist (acid+basic, monophase, enzymatic+disinfectant, etc.), and also timing/schedule greatly differ among different applications. Most often, CIP is applied on a fixed time-basis, without any check on the real need or efficacy. Unfortunately, being microbiological growth a dynamic phenomenon, influenced by plenty of variables, a "one for all seasons" cleaning strategy does not exist. For this reason, a check on CIP real effectiveness is needed, to avoid microbiological issues like proliferation of pathogens, microbial corrosion and others.

ALVIM Biofilm Probes help to detect and monitor bacterial settlement and growth inside water lines, tanks, and other surfaces in contact with the water and other liquids allowing to check, at the same time, the efficacy of CIP, sanitation and biocide treatments.

The ALVIM Biofilm Monitoring System has been already used to check and optimize Clean-In-Place treatments in:

Standard laboratory analyses (culturing techniques / plate count / HPC) have many limitations, since they are:

time-consuming, they usually require 24 - 72 hours;
poorly representative of the real abundance of bacteria, since less than 1% of the bacteria present in a sample will grow in lab conditions;
applied to water samples, but most bacteria live in biofilm, not free in the water. It is well known that the two phenomena are mostly unrelated: after the settlement of the first free-floating bacteria coming from the water bulk, biofilm dynamics are almost completely unrelated to the presence/number of bacteria in the water, since the settled ones will grow exponentially, duplicating themselves.

Bacteria detection kits are receiving a growing interest, since they provide a first screening in a short time. Unfortunately, the results provided by such kits are not always representative of the actual presence and abundance of bacteria in the piping system, e.g. if they are applied to water samples, as explained above. Moreover, bacteria detection kits provide a "spot" measurement, not an online, continuous indication of bacterial growth.

Automated process systems for the Brewery Industry

marizelle@instek.co.za (Instek Control) — Tue, 03 Apr 2018 18:21:48 GMT

ADos – Additive Dosing: The additive dosing system ADoS is used for dosing of ingredients such as malt extract, hop extract, flavours and colours directly into the main product stream. The compact system provides a high degree of flexibility for the production of different products (brands).

In additive dosing smaller or larger amounts of ingredients are dosed directly into the main product stream according to a preselected recipe. The number of components can be adapted to meet individual needs. There are various possibilities to supply the additives, e. g. out of separate tanks via supply lines or out of smaller vessels located on the skid. Optionally, the vessels can be heated, purged with CO2 or N2 or equipped with agitators. Reliable flow meters, dosing pumps and pneumatic control valves permanently measure and adjust the quantities. Thus, highly accurate repeatable dosage of even smallest amounts is guaranteed. The modular system design allows for easy expansion, e. g. for mixing with deaerated water, carbonation or pasteurization of the finished product.

Application cases - SOFT DRINK PRODUCTION - solution for Biofilm....

marizelle@instek.co.za (Instek Control) — Wed, 07 Mar 2018 18:27:22 GMT

Bacterial growth on surfaces in contact with water and other liquids (a phenomenon usually known as “biofilm” or “bacterial slime”) causes many issues in Food and Beverage Production. Indeed, such bacterial layer is the ideal environment for the proliferation of pathogens. Moreover, biofilm is much more resistant to sanitation that free-floating bacteria, and this resistance increases with time.

In this soft drink production plant, Clean-In-Place(CIP) was applied on a scheduled time-basis. To verify the real effectiveness if CIP treatment against biofilm, the Customer decide to install an ALVIM sensor in the feed water line of the beverage production plant. The following data illustrate the most relevant results of the biofilm monitoring that was carried out in this industry over several months.

As it can be seen in Figure 1, the Alvim Sensor detected biofilm growth about 10 days after the installation in the soft drink production plant. Since the Alvim Technology detects biofilm growth from its very early phase (first layer of bacteria), the scheduled CIP treatment, that was applied a couple days after bacterial growth, easily removed biofilm.

After some weeks, the Alvim probe detected biofilm growth again (Fig.2). Also in this case the scheduled CIP treatment was applied a couple days after bacterial growth and, again, the cleaning treatment completely removed biofilm.

The ALVIM Sensor demonstrated that the application of CIP was timely enough, during the considered period, even if a small adjustment (anticipating the treatment of 4-5 days) would have prevented bacterial growth inside pipelines even better.

The indication provided by the Alvim Biofilm Monitoring System allowed to check, on line and in real time, the actual need of a cleaning treatment, and the effectiveness of CIP.

CRAFT COLUMN WATER DEAERATION (COLD)

marizelle@instek.co.za (Instek Control) — Tue, 06 Mar 2018 18:49:03 GMT

High improvement of quality - minimum investment costs! Optional high precision OXYTRANS O2 sensor for process control.

For the production of quality beverages with long shelf life, and to prevent corrosion of boiler and piping systems, water needs to be deaerated. Deaeration is performed at ambient temperature. The water is dispersed at the top of the column. The column contains densely packed, thin stainless steel sheets arranged in such way that the water takes multiple paths as it flows down through the column. This maximizes the transfer surface and the contact time between the water and the strip gas (CO2 or N2). The strip gas is fed into the bottom of the column and flows upwards inside it in counter current to the water. The large partial pressure difference of O2 forces the oxygen out of the water into the gas phase. At the top of the column the removed oxygen leaves the system as a gas, together with the undissolved strip gas. The O2 content of the deaerated water can be permanently monitored by a Centec OXYTRANS sensor. The virtually oxygen free water is collected at the bottom of the column. The system can be supplied pre-assembled or as an assembly kit for minimum investment costs. Contact Instek Control for the DATASHEET and for more information; info@instek.co.za / 012 998 6326

UV vs Chemicals

marizelle@instek.co.za (Instek Control) — Thu, 30 Nov 2017 13:27:20 GMT

The major advantages of ultraviolet light versus chemicals: no residuals, no disinfection by-products, no effects on color, taste, odor, no storage of chemicals, effective against all microorganisms, including Giardia and Cryptosporidium, compact footprint, environment and human friendly

Ultraviolet light

Ultraviolet (UV) light is a natural part of sunlight; the short wavelengths are absorbed by the protecting ozone layer. UV lamps designed for water disinfection use a gas mixture containing the element mercury (Hg) vapour to produce ultraviolet light.

Mercury is an advantageous gas for UV disinfection applications because it emits light in the germicidal (‘germs killing’) wavelength range (UVC and UVB). The light output depends on the concentration of mercury atoms, which is directly related to the mercury vapor pressure.

Mercury at low vapour pressure produces essentially monochromatic (single wavelength) UV light at 253,7 nm, so-called low-pressure UV lamps.

At higher vapour pressures, the frequency of collisions between mercury atoms increases, producing UV light over a broad spectrum. These so-called polychromatic (more wavelengths) medium-pressure lamps have an overall higher intensity.

Exposure to UV light in the wavelength spectrum of 200 – 400 nm damages the genetic (DNA and RNA) and other molecules inside a micro-organism. The damage ‘kills’ the specific micro-organism.

Bacteria, protozoa, viruses, fungi, algae are all sensitive to UV light. Because of differences in their shape, they are sensitive to different wavelengths.

Applying UV light does not leave residuals in the water, which is an advantage over chemical disinfection methods. UV is proven to be very effective in inactivation of Giardia and Cryptosporidium with a very low dose.

Chlorination

The use of chlorine as a disinfectant is commonly accepted worldwide. People are becoming more concerned about the by-products of chlorine as it reacts with other organic compounds producing various compounds like e.g. trihalomethanes (THMs). THMs are documented as probable or possible human carcinogens.

Other disadvantages of chlorination are how it changes of taste and odours, the need for additional equipment such as tanks to guarantee proper contact time, and necessary monitoring to ensure proper concentration levels.

Chlorination is known to provide poor disinfection performance against viruses such as enterovirus and hepatitis A and microorganims such as Giardia and Cryptosporidium .

Ozonation

Ozone, one of the strongest oxidants known, is effective as an oxidising agent in reducing bacteria with a relatively short exposure time. Ozone generators are used to produce ozone gas on-site since the gas is unstable and has a very short life.

These systems must be carefully installed and monitored because high levels of ozone will oxidise and deteriorate all downstream piping and components. High levels of ozone are extremely harmful, especially in enclosed or low ventilation areas.

Furthermore ozone forms highly carcinogenic by-products at high bromide levels such as bromate, bromoform, dibromeacetic acid etc. This is becoming an even bigger concern with drinking water disinfection.

As a result of by-product formation some countries have already banned ozone for drinking water treatment.

bestUV Lamp Technology

marizelle@instek.co.za (Instek Control) — Tue, 14 Nov 2017 18:53:18 GMT

Two lamp technologies, low-gas pressure (LP) UV lamps, mainly for disinfection and ozone destruction and medium-gas pressure (MP) UV lamps for disinfection

Low-pressure (LP) UV lamp

Low-pressure (LP) UV lamps have some important differences compared to medium-pressure (MP) UV lamps:

low power
efficiency
larger size
greater quantity needed in a UV reactor
limited range of wavelengths (254nm) emitted

Some applications use of low-pressure UV lamps, mainly because of:

low capacity (single UV lamp)
frequent STOP and GO operations

Two other important reasons to use low-pressure UV lamp technology are:

high efficiency of the lamp, up to 40% of the power converts to germicidal energy,
specific 254 nm wavelengths, well known for disinfection purposes.

Medium-pressure (MP) UV lamp

A medium-pressure (MP) UV lamp has some important differences compared to the more well known low-pressure (LP) UV lamps. These differences are major reasons to select UV systems with medium-pressure lamps:

high power
energy efficiency
compact size
reduce quantity needed in a UV reactor
broad range of wavelengths (200 – 400nm)
photobiological effects

Some applications may require the use of medium-pressure UV lamps because they emit a broader range of wavelengths. Such applications include:

dechloramination in public swimming pools (reduction of all chloramines, mono-, di- and trichloramines, only reached by the emission of wavelengths between 200 and 400nm.

Two other important reasons to use medium-pressure UV lamp technology is:

to reduce the footprint of the installation, as high-powered medium-pressure lamps greatly reduce the size of a UV reactor.
to reduce the quantity of UV lamps because medium-pressure UV lamps have higher power fewer are required compared to a low-pressure UV lamp systems.

What is UV light?

marizelle@instek.co.za (Instek Control) — Tue, 07 Nov 2017 18:30:33 GMT

Ultraviolet (UV) light is part of the electromagnetic spectrum between visible light and X-rays.

The UV spectrum is divided in 4 ranges:

UVA

This range extends from wavelengths between 315 – 400 nm (nanometer). Light in this range is absorbed by the skin and leads largely to “sun tanning”.

Application for these wavelengths:

attraction of insects
katalysation of titaniumdioxide (TiO2)
breakdown of trichloramine, part of ‘chlorine smell’ in swimming pools

UVB

This range extends from wavelengths between 280 – 315 nm. Light in this range is also absorbed by the skin but leads largely to “sun burning”.

Applications for these wavelengths:

inactivation of microorganism, as DNA absorbs wavelengths below 315 nm
breakdown of dichloramine, part of ‘chlorine smell’ in swimming pools
breakdown of ozone

UVC

This range extends from wavelengths between 200 – 280 nm. This range is absorbed by DNA and RNA (genetic molecules) in micro-organisms and leads to their inactivation (‘killing’) by inhibiting their ability to replicate.

Applications for these wavelengths:

inactivation of microorganisms, as DNA/RNA absorbs at maximum wavelength of 260-270 nm
breakdown of ozone, hypochlorite, hydrogenperoxide
formation of hydroxylradicals

Vacuum UV

This range extends wavelengths from 100 – 200 nm. It is called “vacuum UV” since UV light in this range is strongly absorbed by water or oxygen in air and can thus only exist in vacuum.

Applications for these wavelengths:

production of ozone, active oxygen
dissociation of chemical bands

DENSITY AND MOISTURE CONTENT MEASUREMENT

marizelle@instek.co.za (Instek Control) — Mon, 09 Oct 2017 16:55:17 GMT

Werne&Thiel has been in the field of moisture measurement techniques for 35 years. They specializes in the measurement of moisture in different kinds of materials such as Cement/ Ready-mix, Drying Ovens, Grain Measurement, Weighing Containers, Wood Chips, Sand, Dewatered Sewage Sludge, Dried Powder and Wood Pellets. This could include dry products such as coffee, milk powder, grain, maize wheat and flour. Virtually any dry product on the market can be measured for moisture content.

DENSITY MEASUREMENT

OLAS (Optical Light Absorption Sensor) Absorptiometry and density measurement. This Sensor (OLAS), fabricated by Werne&Thiel GbR sends light into the material of interest (medium) and makes use of the accurately measured absorption of light to determine the composition of medium.

With this method not only the composition of water slurries, suspensions and composite materials of all kinds (e.g. cement slurry, chemical pulp, etc.) can be determined, but also the thickness of foils and coatings and much else. Whatever in production, manufacturing or processing results in a change of absorption of light of medium can be measured, monitored and controlled by the OLAS .

Density measurement in concrete residual water. The development of the OLAS measuring system, an online measuring system, that determines the solid content of concrete recycling water, was initiated years ago. It has been established into a reliable and economic measuring system reaching product maturity. OLAS, named after its functionality namely:

Optical Light Absorption Sensor, makes use of a sophisticated and modernized infrared absorption measuring method, in which the measurement of light is introduced into the medium through optical fibres.

When desired, OLAS can be supplemented by the OLASTPC (OLAS Touch Panel Controller), an optimal evaluation that functions as a display and control unit that forms a complete measurement system.

Simple, straight forward and tremendously effective

marizelle@instek.co.za (Instek Control) — Wed, 04 Oct 2017 20:30:50 GMT

Without any doubt the best mixing system for carbonation and mixing of liquids and gasses to date - Venturi Vortex Injector by Centec GmbH.

Giovanni Battista Venturi “discovered” the venturi effect in 1797, and ever since the Venturi effect have been in use in fluid and airflow mechanics over a range of disciplines ranging from Aeronautics to Farming, and everything in-between.

For the Food and Beverage Industry, Centec GmbH developed the Vortex Injector using the same principle to create arguably the best mixing system for carbonation and mixing of liquids to date.

The working principle is straight forward. Fluid moves through the inlet chamber where it is accelerated and pressurized.

Moving through the mixing chamber there is an immediate pressure drop that opens the liquid and creates a vacuum. This creates conditions for a near perfect fusion of liquids and or gases. The gas or liquid is injected into the product through multiple nozzles around the circumference of the mixing chamber. The homogenous mixing of the products take place instantaneously.

The Centec Vortex Injector is especially designed for the homogeneous mixing of liquids and Gas, e.g. CO2, O2 or N2, with beer, wine, or other beverages.

Because this system is so effective the dissolving times are greatly reduced and the dosing can be done precisely and accurately. It is a proven system implemented in major Breweries, Wineries, and Soft Drink concerns.

THE NEW HYGIENIC BIOFILM MONITORING SENSOR

marizelle@instek.co.za (Instek Control) — Tue, 05 Sep 2017 07:41:12 GMT

With Hygienic connection to the process, flat surface in contact with the liquid and high resistance to chemical treatments, this model is indicated for applications where hygiene is critical.

Bacteria settle among any structure (pipelines, tanks, machinery) in contact with the water in a very short time, if appropriate preventative measurements are not applied. The ALVIM real-time, on line, Biofilm Monitoring System is able to detect bacterial settlement since its first phases (down to 1% of surface covered by micro-organisms such as Legionella pneumophila) and, based on these data, manually or automatically adjust and optimize cleaning treatments / biocide treatments. This way keeping biofilm growth under control.

What is biofilm?

The terms biofilm refers to the layer of micro-organisms (bacteria, diatoms, fungi, etc.) that grows on any surface in contact with water or other liquids. It has been demonstrated that biofilm can grow even in extreme conditions, causing damages that can range from Legionella contamination to Microbiologically Influenced Corrosion (MIC).

Important advantages of the ALVIM technology compared to other sensors in the market

discriminates between biofilm and other kinds of deposit/fouling (e.g. calcium carbonate, etc.); this is extremely important, since these two different kinds of fouling requires different treatments;
has a very high sensitivity, i.e. detects biofilm initial colonization phase; indeed, many biofilm related problems, such as Microbiologically Influenced Corrosion (MIC), start as soon as the first bacterial spots appear on a surface.
Early-warning detection of bacterial biofilm growth by measuring the natural electrochemical activity of bacterial biofilm, indicating its real presence and extent in a given moment.
Optimization of cleaning treatments (biocides, disinfectans, ...)
Easy to install, easy to operate
Virtually maintenance-free probe
Real-time, continuous biofilm monitoring

Operating conditions for the NEW ALVIM SENSOR - AX03S3

Temperature: -10<T<+150°C (to monitor biofilm growth: +2<T<+40°C)

Oxygen: >1ppm

Pressure: <10 bar

Conductivity: >30 µs/cm

Data Communication Wiring: 4-20mA and RS485/MODBUS RTU

How do brewers measure the alcohol in beer?

marizelle@instek.co.za (Instek Control) — Tue, 15 Aug 2017 07:12:15 GMT

Alcoholic strength and measurement in beer is generated as a function of both the quantity of fermentable sugars originally present in beer wort and the extent to which those sugars are actually fermented by yeast. The initial original gravity of wort is a measure of the specific gravity (SG) of the wort at 20°C (where, simplified, water at a standard reference temperature has an SG of 1.0000) and is also known as the original extract. INSTEK CONTROL are able to provide solutions of superior reliability and precision.

We have exciting and accurate sensor technology that will ensure that products are produced to consistently high standards, and that processes run with optimized efficiency, to consume the least amounts of energy and raw materials. Our systems and sensors are used in brewery and beverage industries throughout the entire manufacturing process. Centec, one of our suppliers, stand for comprehensive expertise in the cold process area of the brewery.

Alcohol Measurement Sensors for the Brewery Industry:

- ALCOHOL MONITOR measures the content of alcohol (ethanol) in a mixture of water and ethanol. The alcohol measurement is done during the production of beer and beer-based mixed drinks.

PROVEN APPLICATION - ONCE OFF INVESTMENT

marizelle@instek.co.za (Instek Control) — Wed, 12 Jul 2017 11:46:33 GMT

New to Micro-Breweries

Micro-breweries normally are not automated and all their processes are done manually. They don’t have many employees. An estimate of 4000 hectoliters beer per year are produced by Micro-Breweries and they don’t see the point of investing in hygienic or any other instrumentation for their processes.

Lately these facts changed!!

Checking concentration of the cleaning agent in a bottling machine are one of the most important steps, even if you are a Micro Brewery, and very time consuming for a business with a few employees.

A Brew master from one of the Micro-Breweries explained why: “ If the cleaning agent gets diluted with water, the cleaning of the bottles is not done properly anymore. When that happens, it could take hours until we check again and notice the problem. In the meantime, the filling of bottles of course continues. The bottles which are filled in that period would not be cleaned properly. That would be a huge problem for us. We can't send out bottles if we don’t know exactly that they are clean. Otherwise our reputation could be damaged and very difficult to restore again.”

Therefore they invested in the ILM-4 Conductivity Meter from Anderson-Negele .

" We installed the ILM-4 in the filling machine and connected an optical and acoustical alarm to it. So if there is a problem we can see or hear it and immediately stop the filling process."

There is a huge growing market for small local "craft breweries" . For those of you who have a bottle filling machine, this application could be interesting as well. Contact INSTEK CONTROL for more information.

A brand new De-aeration Plant

marizelle@instek.co.za (Instek Control) — Fri, 30 Jun 2017 07:25:04 GMT

Instek Control delivered a Centec De-aeration system at one of South Africa's biggest Breweries, June 2017

Through the course of 2016 and early 2017, Instek Control delivered four Centec, DeGaS – Cold de-aeration skids to major brewing facilities in Southern Africa. We are proud to say that the number did not stop at four.

On 27 June 2017, another De-aeration skid was delivered at one of the bigger brew houses in Southern Africa. These systems were manufactured to the different clients’ requirements and requests.

In the food and beverage industry, dissolved oxygen has adverse impact on flavour stability and shelf life. The de-aeration system DeGaS-Cold removes oxygen from water that is used for the production of beer and beer-based mixed drinks and soft drinks.

In other industries dissolved oxygen plays a major part in piping erosion and boiler deterioration.

Centec also manufacture these plants for the smaller Craft brewers, and have models available to suit the desired output, quality levels, and budgetary constraints.

Send us your details and we will get back to you with more information on these process skids.

Centec’s systems and sensors are engineered to perfectly meet the most demanding requirements of the brewery, beverage, food and pharmaceutical industries.

Alternative to traditional measurement systems

info@instek.co.za (Instek Control) — Tue, 02 May 2017 00:00:00 GMT

LTM-2 level measurement probes from Instek Control cc are aimed as being an alternative to traditional measurement systems still employed throughout the flotation industry.

Designed and developed in Germany, the LTM-2 probe was specifically made to meet flotation challenges in the industry. This probe is a two-wired loop and is made from high grade stainless steel. With no moving parts and using the Electro Potentiometric Effecta, a patented form of conductivity it is able to determine pulp/froth interface.

Booysendal Platinum’s concentrator plant in 2016 agreed to prelimenary trials on a unit supplied by Instek Control's distributor in the Mpumalanga and Linpopo area, Redland Engineering cc. The LTM-2 probe was trialed on a column float cell, a cleaner float cell and on a concentrate sump , all applications known to pose difficulties IRO accurate level measurement when utilising conventional measurement methods.

Prior to these trials, level measurements were achieved by means of a bubbler for these columns, a ball-and-striker plate for the cleaner float cells and an ultrasonic level sensor on the concentrate sumps. All methods posed challenges, which can result in production losses, i.e.

Bubbler’s on Column Floatation:

Variations in air supply to the bubbler tube affected the bubbler level readings
Bubbler level readings are sensitive to density changes in froth and pulp phases
Frequent chokes occur on bubbler tubes
Calibration on bubbler tubes is labour intensive and needs to be carried out on a regular bases
False level readings cause instability to down-stream processes as well as unnecessary wear on control valves

Float Balls, Striker plates and Ultrasonics on Floatation Cells

Losses occur due to either the ball and striker plate “getting stuck” or when the float ball detaches itself from the rod.

Ultrasonics on Concentrate Sumps

Froth buildup in the concentrate sumps results in false high level readings which in turn reduces the masspull in the float cells feeding into them (Floatstar controls the air on the float cells according to the level reading from the concentrate sump). The reduced masspull decreases the level in the sump whereby this scenario creates even more froth and the net result is production losses due to low masspulls and unstable operation due to concentrate pumps cavitating.

The LTM-2 probe had the following advantages when installed in place of the ultrasonics:

No moving parts
Not density dependent
Not sensitive to froth or product build-up
Set up can be achieved in less than 5 minutes
The LTM probes are Virtually maintenance free
The unit accurately measures the pulp/ froth interface and provides a stable feedback signal at an optimal update rate, without excessive “damping” all of which provides improved process control and stability

Booysendal Platinum subsequently have replaced all bubbler tubes with LTM-2 probes and will consider phasing in LTM-2 probes in the concentrate sumps on the cleaner circuit and with a view to implement them in the flotation cells in the future.

The following trends and observations were provided by Booysendal Platinum to indicate the advantages of the LTM-2 probe compared to the conventional level detection systems.
