BSG are major by-products in the beer production. However, high moisture (80-85%) brings a lot of problems on utilization and transportation. Today the best way to solve this problem is to dehydrate BSG and transfer them into composite feed, which could be effectively absorbed. According to the need of different livestock, people could make variable feed by adding specific additive such as trace element. By this way, BSG could get fully used, which could bring priceless environmental benefits and economic benefits. (For more information about my company)
BSG with 85% moisture are delivered into the screw dehydration machine (or belt dehydration machine) and dehydrated to 50% to 60% moisture content. Then the dehydrated product was delivered into the rotary dryer by screw conveyor for the drying process. High-temperature air heated by furnace could has full massl and heat exchange with BSG, taking away the moisture. The dry materials could pass through the drum quickly with the air force. Wet materials would be dropped gradually and get the fully dried. The eventual dry materials would be delivered out of the systems through screw conveyor.
