Talking about the composition and principle of belt type dehumidifying dryer——Hengrong Machinery

2018-05-07
In the pigment production industry, people mainly use a belt type dehumidifying dryer to dry and air dry them; belt type dehumidifying dryers can effectively help the pigment production industry to solve the problem of desiccant drying of pigments, and thus are widely used in pigments and other industries. The following Hengrong Machinery mainly introduces the composition and principle of the belt dehumidifying dryer.

The belt type dehumidifying dryer is composed of a preforming machine, an automatic sheet feeding device and a dedicated belt drying host. When drying, the materials are first made into pellets by a preformer, and then evenly spread on the mesh belt by an automatic spreading device. With the forward movement of the mesh belt, the materials are blown by the hot air to achieve the purpose of drying.

The belt type dehumidifying dryer spreads the material evenly on the mesh belt (stainless steel woven net, PTFE non-sticky nylon mesh). The mesh belt adopts 8-100 mesh stainless steel mesh and is dragged by the transmission device to move in the dryer. Dryer of 4-20 units, each unit is independently a hot air circulation, the moisture is discharged by special part humidity fan, the exhaust gas control valve, a hot gas from top to bottom or from the top down through the mesh material covered The belt completes the heat and mass transfer process and removes material moisture. The mesh belt moves slowly, the operating speed can be adjusted freely according to the material temperature, and the dried product continuously falls into the receiver. The upper and lower circulation units can be flexibly equipped according to the needs of users, and the number of units can be selected according to the needs.

DEHUMIDIFER belt is used a continuous drying apparatus, especially for better ventilation sheet, strip and dried, granular materials, paste materials like cake, also by a pelletizer or extruding mechanism Dry after molding. Can be widely used in chemical, food, medicine, building materials, electronics and other industries
