Spent grain drying machine:

It is designed according to the principle of superposition compression, and mainly relies on the cooperation of the feed box, the screw shaft, the screen and the tail cone to achieve the purpose of separation of spent grain and water. Wet spent grain are evenly transported to the feed bin of the screw extrusion dehydrator through tools such as screw conveyors. After being squeezed by the screw blades and filtered by the screen, the water or juice flows through the screen to the water collecting tray under the spent grain drying machine for collection. And the dry spent grain will be output through the conveyor belt.
