BEER CLARIFICATION PROCESS BY CROSSFLOW-MICROFILTRATION |
摘要 |
<p>The invention relates to a process for the crossflow micro-filtration of beer. In order to prevent the clogging of the membrane of the filter module by components of the non-clarified beer which are to be filtered out and settle in the form of a covering, the filtration is interrupted at intervals. In a subsequent brief pause the covering on the membrane is chemically and partially dissolved with a caustic solution whereafter the covering is subsequently removed by backwashing of the membrane with water. In order to further improve the filtration, the transmembrane pressure (p) is regulated during the filtration phase according to a substantially periodic time function, and the crossflow velocity (v) of the beer over the membrane is increased substantially continuously.</p> |
