Abstract

A cutting or breaking up device 11 is built into a straining tun 10, which is set in rotation following a certain draining off time, in order to loosen up the brewer's grain cakes which have built up on the screen base 15 of the straining tun 10. Cutting device 11 has an upright, motor-powered shaft 16, to which are fastened a plurality of horizontal arms 12, which in turn support rows of cutting blades 13A, 13B. At the bottom ends of these cutting blades 13A, 13B in turn are fastened at least two cutting shoes 14, which cause a rapid, intensive loosening up of the brewer's grain cake upon rotation of the cutting device 11.
