Mesh-belt drying equipment follows the design of continuous production framework

The material to be processed is evenly laid on the mesh by the feeder. The mesh is made of 12-60 mesh stainless steel wire mesh. Drive by transmission device to move in drying equipment. The mesh belt drying equipment consists of several units, each unit has an independent hot air circulation, some exhaust gas is discharged by a special exhaust fan, the exhaust gas is controlled by a regulating valve, and the hot gas passes through the material laid on the mesh belt from bottom to top or from top to bottom, heating and drying and taking away moisture. 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 user needs, and the number of units can be selected according to needs. The material in the hopper 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 drying equipment. The drying equipment is composed of several units, each unit has an independent hot air circulation. Some of the exhaust gas is discharged by a special exhaust fan, and the exhaust gas discharged from each unit is controlled by a control valve. In the upper circulating unit, the wind from the circulating fan enters the lower chamber of the unit through the side duct, and the air is heated upward through the heater. After distribution by the distributor, the air is blown to the mesh belt as a jet stream, which passes through the material and enters the upper chamber. The drying process of

is the process of heat and mass transfer through the material layer by hot air flow, and the upper chamber is connected by the air duct and the inlet of the fan. Most of the gas cycle, a part of the lower temperature and higher moisture content of the gas as exhaust gas through the dehumidifier pipe, regulating valve, dehumidifier exhaust. In the lower circulating unit, the air coming from the circulating fan enters the upper chamber first, heates downward through the heat exchanger and enters the lower chamber through the material layer. The lower chamber is connected with 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. Upper and lower cycle units can be flexibly equipped according to user needs, and the number of units can also be selected according to needs.

mesh-belt drying equipment is used for dehydrated vegetables and three equipment are usually used in series to form initial, middle and final drying sections. In the initial drying stage, because of the high moisture content of the material. Because of poor air permeability, smaller paving thickness, faster running speed and higher drying temperature are adopted. In the initial drying stage, the temperature of dry gas can be as high as 120oC. The residence time of material in the final drying section is 3-6 times as long as that in the initial drying section, and the thickness of paving material is 2-4 times as thick as that in the initial drying section. For material temperature not exceeding 60 oC, dry gas of about 80 oC can be used. The performance of belt drying equipment can be better developed by using multi-stage combination, and the drying is more uniform.

mesh belt drying equipment follows the design of continuous production structure, providing various types of drying equipment selection scheme and quotation. This article is from the microwave dryer () network.
