There is a growing demand for beer grain drying in the market, but the relevant understanding of drying equipment is asymmetric information. Some users invest in wine grain drying equipment for the first time, so it is inevitable to encounter evaluation errors and procurement pitfalls in procurement. Dingli suggest that the first thing is to understand the operation of spent grain dryer equipment knowledge and relevant information.
The running state of the beer dry can be summarized as follows:
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 spiraling pattern, which realize 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 are vibration cleaning device, which could prevent the adhesion between materials and drum.Hot fluid(air) flow:Cool air is compressed into 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.
In general, brewer's grain dryer must meet the following requirements, so as to guarantee the drying quality and efficiency of beer spent grain, and ensure the fundamental interests of users:1. Beer waste drying has high mechanization degree, large production capacity, and can run continuously. 2. Beer lees dryer has excellent structure, simple structure, stable operation and convenient operation of materials through cylinder resistance. 3. Beer lees dryer has few faults, low maintenance cost and low power consumption. 4. Product drying uniformity is good. 5. No odor after drying.
