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.

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 Centec Vortex mixer is a hydrodynamic fitting for the mixing and dispersion of multiple liquids and further applications include additive dosing of liquid ingredients (e.g. flavors, sweeteners, vitamins, colors) to a main stream.

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

·        Instant, homogenous Mixing and additive dosing of liquids and gasses.

·        Designed for each specific application 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.

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

  1. 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;
  2. 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.
  3. 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.
  4. Optimization of cleaning treatments (biocides, disinfectans, ...)
  5. Easy to install, easy to operate
  6. Virtually maintenance-free probe
  7. 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

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.
