The rapid drying of bean dregs adopts the flash dryer, which has the advantages of small footprint, low energy consumption, high thermal efficiency, and continuous mass production. The dry material recovery efficiency is high, and the dried bean dregs are white and clean, not blackened or pasted The particle size is uniform and fine. The use of flash dryer to dry bean dregs is mainly used for cat litter production. Zhengzhou Dingli customizes the production of various types of bean dregs flash dryer equipment, the price is reasonable, the flash dryer is environmentally friendly and low consumption, and the technology is mature.

The cyclone flash dryer is composed of drying host, feeder, heat source device (hot blast stove or steam), air filter, blower, cyclone separator, bag filter, induced draft fan and other key components. The hot air enters the bottom of the dryer tangentially and forms a powerful rotating wind field driven by the agitator. The paste material enters the dryer from the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force. The block material is quickly crushed, fully contacted with hot air and heated ,dry. The dehydrated dry material rises with the hot air flow, the large particles are intercepted by the grading ring, and the small particles are discharged from the center of the ring to the outside of the dryer and recovered by the cyclone separator and dust collector. , fall back to the bottom to be crushed and dried.
