WEISH-SH Series

• Characteristics of belt dryers: continuous drying in batch production; good air permeability.
• Drying of flake, strip, block or granules;
• Especially suitable for dehydrated vegetables, Chinese Herbal Pieces and other materials with high moisture content and high material temperature;
• Dry cakes may be dried after pelleting or sticking;
• The series dryer has the advantages of fast drying speed, high evaporation intensity and good product quality.

WEISH-SH series belt dryer working principle:

Material is evenly laid on the mesh belt by a feeder. The mesh belt is made of 12 to 60 mesh stainless steel mesh and is moved by a transmission device to move in the dryer. The dryer consists of a number of units. Each unit has independent circulation of hot air. Part of the exhaust is discharged by a special dehumidifying fan. Each unit discharges exhaust gas with a regulating valve. From the top down or from the bottom up, the hot gas passes through the mesh belts covered with the material to complete the heat and mass transfer process and remove the moisture from the material. The mesh belt moves slowly, the operating speed can be freely adjusted 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 also be selected according to the needs.

Remark: WEISH-SH series belt dryer is a continuous drying equipment for batch production, used for the drying of sheet, strip, and granular materials with good air permeability, for dehydrated vegetables, catalysts, and traditional Chinese medicines. It is especially suitable for materials with high moisture content, such as decoction pieces, and material temperature is not allowed to be high; this series of dryers of Pinzheng Drying Co., Ltd. has the advantages of fast drying speed, high evaporation strength, and good product quality. It is also suitable for paste materials of dehydrated filter cakes. It can be dried after being granulated or made into strips. The working principle is shown in the figure below. The material in the hopper is evenly laid on the mesh belt by a feeder. The mesh is a stainless mesh of 12-60 mesh, and it is dragged by the transmission device to move in the dryer. The drying section consists of a number of hot air independent circulation units. Part of the exhaust gas is discharged by a special dehumidifying fan 6, and the amount of discharged gas of each unit is controlled by a regulating valve 7. In the upper circulation unit, the wind from the circulation fan 5 enters the lower chamber from the side air duct, the air flow is heated upward by the heat exchanger 4, and is distributed by the distributor 3, and then the spray is blown toward the mesh belt, and enters through the material and enters. Upper cavity. The drying process is a process in which hot air flows through the material layer to complete the heat and mass transfer. The upper chamber is connected to the inlet of the fan by the air duct, and part of the gas is circulated. Part of the air with lower temperature and higher moisture content is discharged as exhaust gas through the dehumidification pipe, the regulating valve and the dehumidifying fan. In the lower circulation unit, the wind from the circulation fan first enters the upper chamber, and the lower chamber is connected with the inlet of the fan by the side air duct and the return air duct. Most of the gas is circulated, and part of the air is discharged. The upper and lower circulation units can be flexibly equipped according to user needs. You can also choose according to your needs. 1231 is used for dehydrated vegetables. Generally, three sets of equipment are used in series to form the primary dry section, the middle section and the final dry section. In the primary dry section, due to the high moisture content of the material and poor air permeability, a small thickness of the material is used, a faster operating speed and a higher drying temperature. For materials whose material temperature is not allowed to exceed 60°C, in the initial dry section, the temperature of the drying gas can be as high as 120°C or less, and the residence time of the material in the final dry section is 3-6 times that of the initial dry section. The thickness of the material is the initial dry section. 2-4 times. For the requirement that the material temperature does not exceed 60°C, a dry gas at about 80°C may be used. The use of multi-stage combination enables better performance of the belt dryer and more uniform drying.
