The materials are evenly spread on the mesh belt by the feeder. The mesh belt is generally made of stainless steel screen of 12-60 meshes and moves in the dryer after driven by the transmission device. The dryer is composed of several units. The hot air in each unit circulates separately. Some tail gases are discharged by the special dehumidifying fan, and waste gases are controlled by the control valve. The hot air goes through the mesh belt spread with materials from the bottom to the top or from the top to the bottom to complete the process of heat and mass transfer and bring away moisture of materials. The mesh belt will move slowly. Its running speed can be freely adjusted according to material temperature. The finished products after drying will drop into the material collector continuously. The upper and lower circulation units can be set flexibly according to user needs. The unit quantity can be decided according to the needs.
1. Adjust the volume of air, heating temperature,stay time of raw material and feeding speed in order to obtain better drying effect;
2. Flexible equipment configuration,mesh belt flushing system and material cooling system;
3. Most of the air is recycled, achieve the result of high energy savings;
4. The unique points of wind device, make the hot air distribution more uniform, ensure the consistency of product quality;
5. Heat source can be steam, heat conduction oil, electric or combustion (oil) hot blast furnace matching.
