Fermented soybean meal often adopts the method of solid fermentation, adding a certain amount of water, the mixture of soybean meal and wheat bran (100:6) and the combination of Aspergillus oryzae and yeast(1:3). The fermentation time is 72 hours. With our paddle rotary drying equipment, the fermented soybean meal is dried to 12% moisture content instantly at low temperature and then crushed to 30-80 mesh. After being cooled to normal temperature, the whole process ends with the packing of eventual products.

    Material with 50-65% moisture by the screw conveyor into the mixing drum dryer to realize the downstream drying, material constantly be lifted, scattered and put forward with screw type, the material and heat fully exchange heat, the moisture rapidly be evaporated and vaporized, the material which achieves the effect of drying will quickly be discharged from the roller under the hot air.
