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.Air quantity, heating temperature, materials staying time and feeding speed can be adjusted in order to improve drying quality.
2.The equipment configuration is flexible. The mesh belt washing system and materials cooling system are available to use.
3. Most of the hot air is reused to realize energy saving.
4.The machine is equipped with a unique air distributor; it distributes the hot air to the dryer and ensures the quality of products is constant.
5. The heat source can use steam, thermal oil, electricity, oil, or hot air furnace.
