The material is evenly spread on the mesh belt by the feeder, the mesh belt adopts 12-60 mesh stainless steel mesh. It is moved in the drier by the driving device. The drier is composed of several units, each unit hot air circulates independently, part of the tail gas is discharged by a special dehumidifying fan, and the exhaust gas is controlled by a regulating valve, heat and dry and remove moisture. The net belt moves slowly, the running speed can be adjusted freely according to the material temperature, the finished product after drying falls into the feeder continuously. The up and down cycle unit can be flexibly equipped according to the user's needs, and the number of units can be selected according to the needs.
The material in the hopper is evenly spread on the mesh belt by the feeder. The mesh belt is generally made of 12 -60 mesh stainless steel wire mesh, which is driven by the transmission device to move in the dryer. The dryer is composed of several units, each unit hot air independent cycle, in which part of the exhaust gas from a special dehumidifying fan 4, each unit of exhaust gas from the control valve. In the upper circulation unit, the air from the circulating fan (5) enters the lower chamber of the unit from the side air duct, and the air flow is heated upward through heater 7, and after being distributed by distributor 6, the air is blown into the mesh belt as a jet flow, pass through the material into the upper chamber. The drying process is that the hot air flows through the material layer to complete the heat and mass transfer process, and the upper chamber is connected by the air duct and the fan inlet. Most of the gas cycle, a part of the lower temperature and moisture content of the gas as a large exhaust pipe, control valves, moisture fan discharge. In the lower circulation unit, the air from the circulating fan enters the upper chamber first, heats up through the heat exchanger downward, passes through the material layer and enters the lower chamber. The lower chamber is connected with the fan by the side air duct and the return air duct, and most of the gas circulates, part of the discharge. The up and down loop units can be flexibly equipped according to the user's needs, and the number of units can also be selected according to the needs.
Used for dehydrating vegetables, generally using three sets of equipment in series to form the initial dry section, the intermediate section and the final dry section. In the early dry section, due to the high moisture content of the material. Poor permeability, so the use of a smaller thickness of the material, faster running speed and higher drying temperature. In the initial drying stage, the drying gas temperature can be as high as 120OC or above. The material retention time in the final dry section is 3 -6 times of that in the initial dry section, and the material thickness is 2 -4 times of that in the initial dry section. For the material temperature not exceeding 60OC requirements, can use about 80oC of dry gas. The performance of belt drier can be better brought into play by using multi-stage combination, and the drying is more uniform.

Scope of application:
It is suitable for drying sheet, strip and granular materials with good air permeability, especially for dehydrated vegetables and Chinese herbal pieces with high moisture content and high temperature This series of dryer has the advantages of fast drying speed, high evaporation intensity and good product quality. For the paste material of dehydrated filter cake, it needs to be granulated or made into rod shape, then it can also be dried.
Features:
1.The vibration and impact of the material on the belt dryer are slight, and the material particles are not easy to be crushed, so it is also suitable for drying some materials which are not allowed to be crushed.
2.With dryer not only for the material drying, and sometimes also for the material baking, burning or curing operations.
3.Dry machine with complex structure, easy to install, can be long-term operation, failure can enter the box internal maintenance, easy maintenance.
4.Can adjust the amount of air, heating temperature, material residence time and feeding speed to obtain the best drying effect.
5.The equipment configuration is flexible, may use the mesh belt flushing system and the material cooling system.
6.Most air is recycled and highly energy efficient.
7.Unique air distribution device, so that hot air distribution more uniform, to ensure product quality consistency.
8.Heat source can be steam, heat conduction oil, electricity or coal (oil) stove supporting.
