BSG are major by-products in beer production. However, high moisture (80-85%) brings a lot of problems in 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. In this way, BSG could get fully used, which could bring priceless environmental benefits and economic benefits. By considering the situation of the global market, our company cooperated with the relevant designing institute, eventually designing and manufacturing the 'extruding-desiccation machine plus BSG dryer' systems.
The new product line could fulfill continuous and stable production and has the characterization of low cost, easy installation and maintenance, and less need for labor. Meanwhile, the product moisture of the dehydration process and drying process could separately approach 50-65% and 12%, which is satisfying. According to the test report of national feed quality supervision, inspection, and test center, the nutrient in BSG will not lose in the process of dehydration and drying. Currently, we could provide a different series of drying equipment to meet the demand of different beer suppliers.
Brewer's grains dryer mainly consists of a heat source, feeding machines, feeder, rotary drum, discharging machine, draft fan, discharge, and power distribution cabinet.
BSG with 85% moisture is 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 have full mass and heat exchange with BSG, taking away the moisture.
