Belt Dryer Food Vegetable Dehydrator Dryer Machine Ginger Dryer

Product introduction:
Belt dryers are widely used in fruits, vegetables, food, meat, etc., suitable for large-scale production, compact equipment structure, small footprint, simple operation, convenient maintenance, and stable operation. It can be designed into different hot air circulation drying forms according to the drying characteristics of the material. It is an extension and improvement of the hot air circulation oven and is widely used in metallurgical additives, chemicals, food, packaging and other fields. Belt dryers have the ability to meet large-scale production, diversification, centralized control, and continuous production. It has the advantages of high efficiency, energy saving, and easy management. The heating method is diversified, and various heat sources can be selected according to customer needs, such as: air energy, steam, electric heating, etc.

Working principle:
1. The material is evenly spread on the mesh belt by the feeder. The mesh is made of stainless steel wire mesh and is dragged by the transmission device to move in the dryer.
2. The drying section consists of several independent hot air circulation units, part of which is discharged by a special dehumidification fan. The exhaust volume of each unit is controlled by a regulating valve.
3. In the upper circulation unit, the air from the circulating fan enters the lower chamber through the side air duct. The air flow is heated by the heat exchanger upward and distributed by the distributor. It is blown to the mesh belt in a jet flow and enters the upper chamber after passing through the material.
4. The drying process is the process of hot air flow passing through the material layer to complete the heat and mass transfer.
5. The upper chamber is connected to the fan inlet by the air duct. Part of the gas circulates, and part of the gas with lower temperature and higher moisture content is discharged as waste gas through the dehumidification pipe, regulating valve, and dehumidification fan.
6. In the lower circulation unit, the air from the circulating fan first enters the upper chamber, and the lower chamber is connected to the fan inlet by the side air duct and the return air duct. Most of the gas circulates and part of it is discharged. The upper and lower circulation units can be flexibly equipped according to user needs.
