Spent grain screw dewatering machine can be used for the dehydration of beer spent grain, vinegar grain, and other materials, and can remove about 20% of the water in the material. The moisture content of the high-humidity material after mechanical dehydration is reduced to 50-60%, which reduces the burden of the dryer, greatly increases the output, and reduces the fuel consumption in the later stage. In addition, the dehydrated materials are fed more smoothly in the drying process, the heat exchange is more sufficient, and the drying efficiency is improved.
The spent grain dewatering machine is designed according to the superposition compression principle, and mainly achieves the purpose of material water separation by the cooperation of the feeding box, the screw shaft, the screen mesh, and the tail cone. The material to be treated is uniformly conveyed to the feed bin of the screw extrusion dewatering machine by a tool such as a screw conveyor, and is filtered by the spiral blade and filtered by the screen, and the water or juice flows through the screen to the water tray under the machine to collect. After being taken up by the pipeline, the dehydrated finished material is output through the conveyor belt.
Materials:Suitable for beer spent grain, coarse brewers grain, forage, elephant grass, alfalfa, Napier grass, wheat straw, rice straw, beanstalks, potato vines, peanut vines, etc.
Application:Screw pressing brewer spent grain to remove free moisture before drying.
