SILO AND DOSING SCREW
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 fed to a wet spent grains silo plant. The spent grains are loaded on trucks from the silos by a dosing screw for use as animal fodder or for decomposition in agriculture.
The dosing screw features a compensating control that compensates for varying spent grains density, enabling adjustment of the discharge quantity at different filling levels in the silo.
As an alternative, the wet spent grains can be discharged through a measuring container (large rotary valve), e.g. if a dosing screw cannot be used due to limited space.
