Brewer's Spent Grain Drying Production Line

Capacity:  1.53-12.14t/h
Power: 34-155 kw
Application: Widely used for drying brewery spent grain, vinasse, distillers' grain, etc.

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 a loss 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.

Cool Material flow: After the dehydration, BSG is delivered to the cylinder and realize the concurrent drying process. Wet materials are lifted up and down by the internal flights and pushed through three layers in a spiraling pattern, which realizes the heat exchange between cool materials and heated air. The dry materials could pass through the drum quickly with the air force. Wet materials would be dropped gradually and get the fully dried to 10% to 15% moisture. The eventual dry materials would be delivered out of the systems through screw conveyor. Inside the drum, there is a vibration cleaning device, which could prevent the adhesion between materials and drums.

Hot fluid(air) flow: Cool air is compressed into the furnace through blower and heated to 500℃ to 500℃. Then the heated air taken into the drum by draught fan would exchange the heat with wet materials, absorb the moisture and get delivered out of the drum with the temperature reduction of 55 to 60℃. The exhaust gas will be dealt with cyclone dust extractor and wet dust extractor, which would eventually meet the exhaustion requirement.

High performance price ratio

This dryer has a high degree of mechanization, large production capacity and continuous operation.


Energy conservation

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.


Better quality

High heat efficiency. The effect of insulation is as high as 70% and raise heat efficiency by 30%.


Widely used

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.
