A SUPERVISORY CONTROLLED SYSTEM FOR BEER RECOVERY FROM SURPLUS YEAST PROCESS

Abstract

In the manufacture of beer production, the quality of beer and economical operation play key roles. The yeast slurry which is the output product of fermentation process normally at the rate of 2-3% excess to the desired amount. However, such yeast contains 40-70% beer. This substantial proportion of beer must be recovered in economical managed process by applying centrifugal separation technology in beer recovery from surplus yeast process. This process will improve cost-effectiveness without changing the beer quality. The process outputs are approximately 60% beer and yeast. Currently, many breweries in Vietnam do not have such system. This fact motivates us to study and propose solution for beer recovery from surplus yeast process with the supervisory controlled system.
