PROCESS FOR THE SECONDARY PURIFICATION AND

STABILIZATION OF LIQUIDS CONTAINING POLYPHENOLS

AND/OR PROTEINS, PARTICULARLY BEVERAGES

AND MORE ESPECIALLY BEER

Norbert Hums, Helmut Schafft, Landshut, Federal Republic Of Germany assigned to West- falia Separator AG

The present invention concerns a process for secondary purification and stabilization of li- quids containing polyphenols and/or proteins. The liquid to be treated is first subjected to a cen- trifuge, or similar apparatus, which performs the primary purification of the liquid. The treated li- quid is then mixed with stabilizing means that adsorb the polyphenols and proteins and filter means that retain the fine turbidities contained within the liquid. The liquid mixture is then transferred to an alluvial filter apparatus in laminar flow wherein the filter means and stabilization means along with the adsorbed polyphenols and proteins form a filter cake. The purified liquid is then transported to subsequent treatment while the filter cake is subsequently treated with a solution which dissolves the poly- phenols and protein thereby regenerating the stabilization means and the filter means.
