The multi-layer belt dryer machine is continuous drying equipment. The utility model has the advantages of simple operation, high production efficiency, low operation cost, and good drying effect. The equipment mainly adopts the principle of multi-layer utilization of hot air. Then the equipment sends the hot gas generated by the heat source to the dryer through the induced draft fan. Next, the multi-layer mesh belt is rotated to achieve layer-by-layer drying to achieve the purpose of material dehydration and drying.
Structure and working principle of belt dryer machine
The multi-layer continuous belt dryer is mainly composed of a dryer main body, heat source system, feeding and discharging conveying system, electric control system, and other system equipment. It is mainly used to lay the materials on the mesh belt through the homogenizing device. Then the material is dragged by the transmission device to move in the continuous belt dryer. And natural turnover is carried out through a multi-layer mesh belt. The hot air will flow through the materials and take away the moisture of the materials. The water vapor is discharged from the dehumidification hole. So it can achieve the purpose of drying materials.
Features of multi-layer mesh belt dryer
- The mesh belt speed of the industrial belt dryer is adjustable. This not only ensures the residence time of materials but also ensures the quality of materials.
- The homogenizer mechanism is designed according to the characteristics of the materials. This allows the material to receive heat evenly.
- Each controllable unit has an independent fresh air make-up vent, heater, circulating fan, air duct filter, moisture outlet, etc.
- The heater and circulating fan are at the bottom of the belt conveyor.
- The reasonable inclined air guide plate makes the horizontal air distribution of the mesh belt uniform and the temperature difference small. This also makes cleaning easier.
Advantages of belt dryer machine
- The equipment adopts a multi-layer mesh belt structure, with a large drying area. Therefore, it can realize mass continuous production. In addition, the drying process uses pure hot air for drying. That will not pollute the materials in the box.
- Multi-layer mobile stainless steel mesh belt is adopted for transmission. And the hot air flow passes through the mesh belt and the material layer from bottom to top. The multi-layer cycle turnover makes the heat and mass exchange uniform and sufficient. Moreover, the machine has high production efficiency and stable drying quality of materials.
- The multi-layer mesh belt dryer has a homogenizer device. So it can automatically homogenize the thickness of the material layer without manual homogenization and save labor costs.
- Shuliy machinery can customize various types of belt dryer machines according to customers’ needs. Therefore, the machine can meet the drying needs of vegetables, fruits, medicinal materials, chemical raw materials, and other materials on different scales.
