METHOD FOR PROCESSING OF DISTILLERY DREGS AND OBTAINING OF FEED PRODUCT Russian patent published in 2005 - IPC

FIELD: food-processing industry, in particular, processing of after-distillery industry wastes.

SUBSTANCE: method involves withdrawing and feeding suspension for processing; separating suspension into sediment and filtrate; directing part of filtrate back into production circuit; introducing feed additives; mixing sediment with feed additives; drying mixed mass and forming product; separating delivered after-distillery dregs suspension by forced filtering and coagulation process and feeding into mixer for mixing of sediments with feed additives; conveying resultant mass to equipment for drying and forming procedures. Upon completion of procedure for forced filtration of after-distillery dregs suspension, up to 1/3 the total volume of resultant filtrate is directed back into production circuit for mixing of spent wash. Calcium hydroxide is use as coagulant.

EFFECT: simplified process for preparing of after-distillery dregs suspension before drying procedure, reduced power consumption and material usage.
