Beer pre-clarification for extended filter service life and turbidity adjustment
Beer pre-clarification
During beer filtration the brewer often has to face the problem that the beer to be filtered still contains a large amount of yeast. During kieselguhr filtration, a large yeast content inevitably reduces the service life of the filter. With the use of disc stack centrifuges, the filtration process and the operating cycles in the beer cellar can be considerably optimized. In order to operate kieselguhr-free filtration systems (membrane technology, deep bed filtration) in an economical way the use of disc stack centrifuges is essential.
The Flottweg beer separator for beer pre-clarification:
- Longer filter service life
- Reduced beer loss
- Reduced consumption of kieselguhr
- Reduced cleaning and waste water treatment costs
- Gentle treatment of beer and yeast
- Hydro-hermetic sealing of the separator, therefore no oxygen pick-up
Turbidity adjustment
The use of the beer separator offers many advantages with turbidity adjustment as well, especially in the case of wheat beer. The continuous operation of the disc stack centrifuge offers consistent beer quality. The brewer predetermines the required turbidity value in the wheat beer. The control system monitors yeast concentration by measuring the turbidity in the feed and discharge. With the automatic adjustment of different capacities the required separation efficiency can be maintained.
Advantages of turbidity adjustment with the use of the Flottweg disc stack centrifuge:
- Easy handling
- Continuous predetermined turbidity in the wheat beer
- Continuous, fully automatic operation
Green beer clarification
For a continuous and predefined post-fermentation the use of disc stack centrifuges is the appropriate method. By adjusting the desired yeast cell number in the green beer pre-defined process conditions can be generated. Fermentation is sort of standardized.
