Ø The belt dryer is mainly composed of air inlet unit, air exhaust unit, circulating air unit, mesh belt, steam pipeline and condensate discharge pipeline system, moisture exhaust system, feeder, transmission mechanism, control system and other components.
Ø The material in the hopper is evenly spread on the mesh belt by the feeder. The mesh belt uses 12-60 mesh stainless steel wire mesh, which is dragged by the transmission device to move in the dryer. The drying section is composed of several units. The heat exchanger becomes hot air and passes through the material layer to complete the heat and mass transfer process. Most of the gas is circulated, and some of the gas with lower temperature and larger moisture content is discharged as exhaust gas by the exhaust fan.
Ø The frequency of the belt speed is adjustable, which ensures the residence time of the materials and the quality of the finished material;
Ø According to the characteristics of the material, it is designed with a mixing silo and a unique distributing device mechanism, so that the bulk materials can be easily dispersed without affecting the characteristics of the material, the thickness of the material layer is convenient to adjust, and the spread of material is uniform in the longitudinal and horizontal directions of the mesh belt;
Ø Each control unit has an independent fresh air supply port, heater, circulation fan, air channel filter, moisture exhaust port, etc .;
Ø The heater and circulating fan are set at the bottom of the belt machine, and both sides of the belt machine are equipped with quick-opening doors, which is convenient for cleaning and maintenance;
Ø Adopt a reasonable inclined wind deflector to well-distribute the horizontal wind of the mesh belt, the temperature difference is small, and the cleaning is easier;
Ø The belt machine adopts 8 cm of aluminum silicate for heat insulation, with good sealing and good working environment;
Ø The belt machine is divided into five sections and five units, which makes the energy consumption more reasonable and lower;
Ø The bottom of the lower belt of the belt machine is made into an inclined surface, which is convenient for collecting and cleaning materials.
Ø Usage: DW series belt dryer is a continuous drying equipment for batch production. It is used for drying good air permeability materials with sheet, strip and granular shape. It is especially suitable for materials with high moisture content but can’t bear high temperature, such as coconut chips, dehydrated vegetables, pharmaceutical herbal medicines. This series of dryers have the advantages of fast speed, high evaporation intensity, and good product quality. The cake-like paste materials and wet granulation materials can also be dried.
Ø Scope of application: Dehydrated vegetables, pellet feed, monosodium glutamate, coconut chips, organic pigments, synthetic rubber, acrylic fiber, pharmaceuticals, medicinal materials, small wooden products, plastic products, aging and curing of electronic components, etc.
