fabrelac wins “Best Practice Process” with OPTIQUAD-M inline analysis system

Cheesemaker fabrelac from Belgium wins this years’ ITM award “Best Practice Process” for an automation project to continuously monitor and control the product composition.

Variations in the composition are a constant challenge for anyone working with natural products such as milk, which has large fluctuations in the levels of fats and proteins. To gain an advanced form of process control, fabrelac was looking for an inline and continuous measuring solution to monitor and control the product composition.

The Bree-based cheesemaker contacted KROHNE, and after a pilot project to monitor the quality of the raw product with OPTIQUAD-M 4050 W proved successful, fabrelac decided to equip production streams with the inline analysis system: in total, fabrelac now uses 10 OPTIQUAD-M systems to monitor and control the product composition and one OPTIQUAD-WW 4050 W to measure the Chemical Oxygen Demand (COD) in the waste water. 

The ITM jury appreciated the innovative automation approach of fabrelac, not only because of the advanced form of process control and the results achieved, but also because the challenge was on both sides: to make this application possible, fabrelac and KROHNE worked closely together to identify the relevant parameters for each application and make them available within the process control system. By using the inline analyzers, the company manages to maintain a high product quality and constant composition, documented through all process stages, whilst increasing the automation level.

OPTIQUAD-M 4050 W is a spectroscopic analysis system for the continuous in line measurement of protein, fat, lactose and total solids in the production of milk-based products including cheese. It uses up to 12 wavelengths (UV/VIS/NIR/IR - from 200 to 4000 nm) and combines up to four optical principles (transmission, scattering, fluorescence and refraction). The underlying calibration is calculated automatically from reference data specific to the application.

Based on the same functional principle, OPTIQUAD-WW 4050 W is a spectroscopic analysis system for the continuous in line measurement of chemical oxygen demand (COD) in the wastewater flow of dairies or cheese factories.

06/7/2015 - KROHNE’s OPTIFLUX 2100 achieves sparkling results! Over recent years wine has become increasingly popular in the UK and it seems fair to say that its image has changed significantly over this time. It has largely lost its elitist image and has emerged as an alcoholic beverage that is enjoyed by a large number of the population.
06/7/2015 - KROHNE supplies OPTIFLUX 2000 electromagnetic flowmeters for building management energy monitoring For many years now ‘Energy’ has been a hot topic. Energy prices are constantly under the spotlight, and pressure is consistently being applied to businesses and consumers alike to reduce their carbon footprint in order to help meet the government targets for reducing the effects of climate change.
10/4/2015 - VA40 WIM: New option 4…20mA output for variable area flowmeters with glass measuring tube With the new option "WIM", a 4...20mA electrical output signal is now available for the variable area flowmeter VA40. While the flow rate with these glass devices could previously be read only locally, the 4...20mA output option allows for transmission of the measured value for control or evaluation purposes.
17/3/2015 - KROHNE''S Optimass measures fermented potato mash in vodka production When thinking of alcoholic products that are produced in the UK, a fine malt Whiskey may spring to mind or perhaps beer brewed in one of the numerous breweries that can be found dotted around the country.
12/1/2015 - New eLearning course “Vortex Flowmeters: Applications” released A new course on “Vortex Flowmeters: Applications” has been released on the KROHNE Academy online learning platform.
