The belt dryer is widely used in food, chemical industry. It can handle material with big size. As the hot air flows upward and downward, the material can get even drying.
The materials are uniformly distributed on the mesh-belt by the material feeder. The mesh-belt generally adopts 12-60 mesh stainless steel mesh and it is drawn by a transmission device and move inside the dryer. The dryer is composed of several sections. For each section, the hot air is circulated separately. Part of exhausted gas is exhausted by a special moisture exhaust blower. The waste gas is controlled by an adjustment valve. The hot air passes through the mesh-belt covered with bring water material away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material property. The final products after the drying process will fall into the material collector continuously. The top and low circulation units can be freely equipped according to the user's requirements. The number of section might be selected according to the production demands.
1. Amount of air, heating temperature, time of material sticking on the belt and velocity of feeding material can be adjusted in order to obtain the best drying effect.
2. Equipments conjuration is very flexible. It can use the netlike belt washing system and cooling raw material system.
3. Hot air can be circularly applied, the energy is greatly saved.
4.Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products' quality.
5. Heating source can be selected from steam, conducting heat oil, electricity, and coal furnace and oil burner.
