Bean dregs, the by-product of producing soy milk or tofu, is a kind of material with big water and oil combining performance. After being processed, it has the following advantages: fresh bean dregs' water content is about 90%, its nutritional ingredient is higher than many inferior dregs; the crude protein content is high, especially in hot summer and high temperature, it is easily rotted and mildewed. Dry bean dregs' crude protein content is three times higher than that of the unhulled rice. It is suitable for nutrition feed for pig, chicken, duck, etc.
Bean dregs dryer mainly consists of the heat source(hot blast stove or gas producer furnace), material feeder(beater), rotary drying roller, discharger, induced draft fan, driving device, unloader, and power distribution cabinet. After a certain degree of dehydration and scattering, wet bean dregs enters into the drying roller through the material feeder. Under the stirring of the lifting plates and shoveling plates that distribute evenly inside the roller, the bean dregs scatter evenly and contacts with hot air sufficiently in the drying area. This speeds up the drying heat transfer and mass transfer. Wet air is pumped by air-inducing device, which avoids material from being wet again.
Compared with single drum dryer, it reduces floor space by 50%, decreases civil engineering investments by 50%.
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 55-65% to 15% in one-time. Material temperature is always lower than 50 ℃, dried products completely retained the nutrients of fresh bean dregs, 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.
