Pall CBS System

Pall CBS System. New Trends in Colloidal Beer Stabilization. Today consumers expect a beer with a long shelf life free of changes in clarity and appearance. Colloidal stability, in addition to microbial stability, is the main influencing quality criteria for a sufficient shelf life of packaged beer. PVPP stabilization with the classic regeneration process allows repeated use of the PVPP powder combined with candle or horizontal leaf filters. The main challenge with this process is the ongoing movement of the PVPP particles through dosing, stirring and pumping. This causes erosion of the relatively soft PVPP particles enabling the PVPP to pass through the filter candles or screens. The typical loss rate from a regenerable PVPP system is between 0.5 and 2 %. This means in practice, that after 50 to 200 filtrations, the PVPP has been exchanged completely. To overcome these disadvantages Pall has developed with the CBS system a new technology which capitalize on the positive attributes and characteristics of the classical PVPP regenerable process but eliminate the disadvantages.
