SEPARATION OF YEAST FROM FERMENTATION BROTH OF FERMENTATION TANK

摘要

1. A process for separation of yeasts from fermentation broths of a fermentation tank (1) particularly for the production of compressed yeast for baking purposes, as well as compressed yeast from alcoholic fermentation which accrues in the production of alcohol, wine and beer, characterised in that the fermentation broth is forced through a pressure filter with filter elements (30) freely suspended within a filter vessel (21) the filter elements (30) of which are covered with fine filter fabrics or membranes, that after the build-up of a filter cake, the filter vessel (21) is drained of the residual liquid, the yeast filter cake is washed with water, blown out with compressed air or another compressed gas and freed from the filter fabrics by means of a pressure surge with compressed gas in the opposite direction to that of filtration and extracted from the filter vessel (21).
