    This machine is a continuous through-flow drying equipment, which is used for drying flaky, strip and granular materials with good air permeability. It is especially suitable for dehydrated vegetables, Chinese herbal medicines and other materials with high moisture content but not high temperature allowed. This series of dryers have the advantages of fast drying speed, high evaporation intensity and good product quality. For paste materials with dehydrated filter cake shape, they need to be granulated or processed.It can also be dried in rod shape.Material is evenly laid on the mesh by the feeder. The mesh is usually made of 12-60 mesh stainless steel wire mesh, which is driven by the transmission device to move in the dryer.The dryer consists of several units, each unit has an independent cycle of hot air, part of the exhaust gas is discharged by a special exhaust fan, the exhaust gas is controlled by a regulating valve, and the hot gas is passed through the 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 materials.The mesh belt moves slowly, and the running speed can be adjusted freely according to the material temperature. The dried product is continuously dropped into the feeder.Upper and lower cycle units can be flexibly equipped according to users'needs, and the number of units can also be selected according to needs.Working principle
    _The speed of mesh belt can be adjusted by frequency conversion, which ensures the residence time of material and the quality of the discharged material; The mixing bin and unique distributor mechanism designed according to the characteristics of material make the bulk material dispersible easily without affecting the characteristics of material, the thickness of material layer can be adjusted conveniently, and the distribution of material is uniform in the longitudinal and horizontal direction of mesh belt; Each controllable unit has independent fresh air supply air.Mouth, heater, circulating fan, air duct filter, dehumidification outlet, etc. Heater and circulating fan are set at the bottom of belt conveyor, and both sides of belt conveyor are equipped with fast-opening doors to facilitate cleaning and maintenance; reasonable inclined guide air plate is adopted to make the transverse air distribution uniform, the temperature difference is small, and the cleaning is easier; belt conveyor is insulated by 8 cm aluminium silicate, which makes the working ring well sealed.Good condition; The belt conveyor is divided into five sections and five units, so that the energy consumption is more reasonable and lower; The bottom of the belt conveyor low-level mesh belt is made into an inclined surface, which is convenient for collecting and cleaning materials.
