DW Series Multi-Layer Mesh Belt Dryer

DW Series Multi-Layer Mesh Belt Dryer

The belt drier is continuous drying equipment in batch. It is suitable for drying the raw materials that is in the shape of piece, s trip or granule and is good in permeability. Particularly it is suitable for such raw materials that contain high moisture and are not permitted high temperature for example, dehydrated vegetable,catalyst, drinking tablet of Chinese traditional medicine. Its features are fast in drying speed, strong in vaporization, good in quality of products.

Detail

DESCRIPTIONDW Multi-belt Dryer

  DW Series Multi-Layer Mesh Belt Dryer is continuous cross-flow drying equipment for large-scale production of low drying rate materials. The equipment is designed with a compact structure which required small installation area.

  The raw material can be spread on the conveyor belt through suitable mechanism such as star distributor, vibrating belt, grinder or granulator. The conveyor belt will pass the channel that consist one or several drying units. Each drying unit is equipped with air heating and circulating system, and each drying unit has one or several dehumidification system. The hot air will move up and down when the conveyor belt passes though.

 

WORKING PRINCIPLE  

  The material is distributed to the mesh belt evenly by the feeder. The size of stainless steel mesh is 12-16mm mesh. The transmission device will moves the mesh belt around the dryer. The dryer consist a several drying units and each unit has individual hot air circulation system. Part of the exhausted gas is exhausted by an exhaust fan. The waste gas is controlled by an adjusting valve. The hot air will move up and down when the material moving from the top layer to the bottom layer. This process will evaporate the water from the material when the mesh belt moves slowly. The running speed of the conveyer belt can be adjusted according to the material property. The dried material will be automatically discharged to a collector. The circulation units can be equipped according to the user’s requirement and the production demands.

 

FEATURES

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 unique air distributor; it distributes the hot air to the dryer and ensured the quality of products is constant.

5) The heat source can use steam, thermal oil, electricity, coal (oil), or hot air furnace.
