Abstract: The invention relates to a spent grain bunker and a purifying process, wherein the spent grain bunker comprises a housing and a delivery device located in a lower region of the housing, delivering the spent grain out of the spent grain bunker. In order to enable a greater brew cycle and heavily dewater the spent grain, which also can shorten the purifying time, at least one part of the housing is designed as a strainer surface in the lower region of the housing of the spent grain bunker. Thus, when draining the last sparge or drawing the final wort from the purifying tub, the spent grain can be removed into a spent grain bunker, and the remaining fluid can be extracted from the spent grain by a strainer surface in the spent grain bunker.

Abstract: A filter device and a method for the filtration of beer, where, for an improved and simplified filtration, the filter includes a nonfiltrate chamber having a nonfiltrate inlet and a nonfiltrate outlet, wherein the nonfiltrate flows into the nonfiltrate chamber substantially tangentially to the walls thereof, and the bottom of the nonfiltrate chamber is constructed at least partially as a filter. The filter also includes a filtrate chamber underneath the bottom, and a filtrate outlet.
