Dialysis systems
Continuous dealcoholisation
Field of application |
Brewery |
Description |
The plant consists of six operational
units: • the Dialysis membrane modules • a stripper column for thermal alcohol reduction • steam generator unit • feeding unit • diafiltration unit • CIP-Unit The method of dialysis operates on the cross flow principle. In this case, a beer to be de-alcoholised flows through the hollow fibre membrane, whereas a dialysate (thermally treated beer) is feeded to cross flow on outer side of the membrane. The alcohol passes over to dialysate by the power of concentration gradient - drop between beer and dialysate - and is removed in a vacuum rectifier. The de-lcoholised dialysate is feeded at closed cycle to membrane again. |
