Principle：
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.
The advantages :
1. The mesh belt has good gas permeability, and the product drying cycle can be adjusted arbitrarily.
2. The equipment runs smoothly and the materials are not easily damaged.
3. Large drying area and high strength.
4. Hot air circulation structure, uniform temperature and reduced energy consumption.
5. According to customer needs, it can be divided into several units, each unit can control the loop separately.
6. There are various heat source selections, such as electric heating, heat transfer oil heating, hot air heating, etc.
