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. According to the need of different livestock, people could make variable feed by adding specific additive such as trace element. 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 continues 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 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.
This dryer has a high degree of mechanization, large production capacity and continuous operation.
Dryer internal structure using a variety of high-lift board combination mode, effectively regulate the drying process and heat distribution, high heat utilization, exhaust gas discharge temperature is low.
Rapid drying moisture reducing from 65-75% to 14-18% in one-time. Pasture temperature is always lower than 50 ℃, dried grass completely retained the nutrients of fresh pasture, bright color, smell fragrance.
Supporting a variety of new energy-saving clean hot air blast stove, fuel can be diesel, gas, coal, wood, wood chips, straw etc. And efficient energy, heating controllable, simple operation, energy consumption decreased by as much as 30%, power consumption reduced by 20%, the operating cost is lower.
