Features

High thermal efficiency
Adopting the downstream drying method, the material and the heat source air flow enter the drying equipment from the same side, the outlet temperature of the dryer is low, and the thermal efficiency is high.

Energy saving and consumption reduction, high drying efficiency
The rotary dryer adopts a high-efficiency radiator and is equipped with a reasonable air duct so that the hot air can directly contact the material, which greatly improves the drying efficiency of the material and saves energy. The large-area lint collection net is not easy to cause lint blockage, protects the smooth flow of the air duct, and improves the drying effect.

Less component wear
The drum is made of stainless steel bright plate with excellent heat resistance, and the inner wall is smooth, which can reduce the material’s wear on the dryer’s inner wall. The whole machine has strong anti-overload capability, the cylinder runs smoothly, and it has high reliability.

High degree of automation
Computer automatic control is adopted, the degree of drying mechanization is high, the production capacity is large, and it can run continuously. And according to the drying requirements, different drying temperatures and drying times can be configured.

Working Principle

When the bottom of the dryer equipment reaches 400°C-800°C, the material is fed from the feed port by the elevator. It is dispersed and broken under gravity, and the dispersion device is evenly distributed inside the dryer to flow. The hot gas is generated by the lower hot blast stove, moves from bottom to top, contacts with the material, and transfers heat to the material through heat conduction, convection, radiation, and other ways, so that the temperature of the material continues to rise, the water is continuously evaporated, and finally meets the moisture content. The required materials are discharged from the lower outlet, and the fan draws out the gas with water vapor through the chimney.
