Working Principle and Characteristics of Cassava Flash Dryer-Protein Extraction Equipment

The tangent of hot air enters the bottom of the dryer and forms a strong rotating wind field driven by the agitator. Paste material of protein extraction equipment enters cassava flash dryer from screw feeder. Under the strong action of high-speed rotating stirring paddle, the material is dispersed under impact, friction and shearing force. Massive material is quickly crushed and fully contacted with hot air, heated and dried. After dehydration, the dry material rises with the hot air flow, the grading ring intercepts the large particles, and the small particles are discharged from the center of the ring to the dryer. The small particles are recovered by cyclone separator and dust collector. The non-dried or large materials are thrown to the wall by centrifugal force, and then fall back to the bottom to be crushed and dried.

Performance characteristics

  • The organic combination of swirl, fluidization, spouting and grinding classification technology.
  • Compact equipment, small size, high production efficiency, continuous production, achieved
  • Small equipment, large production.
  • High drying intensity, low energy consumption and high thermal efficiency.
  • Material residence time is short and the quality of finished product is good, which can be used for drying heat sensitive materials.
  • Negative pressure or micro-negative pressure operation, with good airtightness, high efficiency, eliminating environmental pollution.

As a new type of equipment, cassava flash dryer has been widely used in the titanium dioxide industry in recent years. In the titanium dioxide industry, the company will continue to adhere to technological innovation, constantly improve the innovation ability of enterprises, and make continuous efforts for the sustainable development of the titanium dioxide industry and drying industry.

Cassava flash dryer is mainly composed of air intake system, heating system, feeding system, drying machine, dust collection system, air exhaust system, control system and so on. When working, the wet material enters the drying room by screw feeder. The material meets the high-speed rotating hot air in the drying room. The fine powder material is moved to the upper end of the drying room by hot air. The material that cannot be taken away falls on the bottom of the drying room. It is smashed by the bottom crushing device. The material is dispersed rapidly, and the contact area between the material and the hot air increases rapidly. Under the action of centrifugal force (there is a grading device at the top), the product with a certain degree of drying and fineness is blown out of the grading device, and the material is quickly dried in the process.
