Spent grains are conveyed to a wet spent grains distribution (silo plant) or to a spent grains drying plant (consisting of dewatering screw press and tube bundle dryer). 

Screw presses are used to pre-dewater the wet spent grains prior to the drying section. This is minimizing the energy demand in the dryer, thus the operating cost, significantly.

Function and principle of operation The wet spent grains conveyor is placed under the lauter tun/mash filter in the brewing house. The spent grains enter the conveying screw of the wet

Function and Principle of Operation As an alternative to drying spent grains at the end of the brewing process (see dewatering screw press / tube bundle dryer), the product can be
