The belt dryer is a continuous flow drying equipment, which is used for drying flake, strip, and granular materials with good air permeability. It is particularly suitable for dehydrated vegetables, Chinese herbal medicine slices and other materials with high moisture content and high temperature. This series of dryers has the advantages of fast drying speed, high evaporation intensity and good product quality. For dehydrated filter cake paste materials, they can also be dried after granulation or rod-shaped.

  The material is evenly spread on the mesh belt by the feeder. The mesh belt generally uses 12-60 mesh stainless steel wire mesh and is dragged by the transmission device to move in the dryer. The dryer consists of several units. The hot air of each unit circulates independently. Part of the exhaust gas is discharged by a special dehumidification fan. The exhaust gas is controlled by a regulating valve. The hot air passes through the multi-layer mesh belt covered with materials from bottom to top or from top to bottom to complete the process of heat and mass transfer and take away the moisture of the material. The mesh belt moves slowly, and the running speed can be freely adjusted according to the temperature of the material. The finished product after drying falls into the receiver continuously. The upper and lower circulation units can be flexibly equipped according to user needs, and the number of units can also be selected according to needs.

  Performance characteristics:

  1. The air volume, heating temperature, material residence time and feeding speed can be adjusted to achieve good drying effect.

  2. The equipment configuration is flexible, and the mesh belt flushing system and material cooling system can be used.

  3. Most of the air is recycled, which saves energy.

  4. The unique air distribution device makes the hot air distribution more uniform, ensuring the consistency of product quality.

  5. The heat source can be equipped with steam, thermal oil, electricity or coal (oil), and gas hot air furnace.
