Introduction of Continuous Mesh Belt hot air drying machine
Continuous Mesh Belt hot air drying machine adopts the principle of hot air . Heat sources of dryer machine for buyer choose :electrical,steam , natural gas , LPG, coal , wood ,biomass.
Host of stainless steel mesh belt, mesh belt on both sides have chain drive, mesh belt is fixed on the poles.Generate heat by Hot stove or boiler furnace, hot air to the bottom of dryer, first through bottom layer of mesh belt with dry materials for heat exchange take away part of water, up step by step through the layers of mesh belt, and material form the counter flow heat exchange, arrived at the top and wet material after heat exchange, there is exhaust Moisture mouth let water vapor get outside when evaporation of water basically reached saturation.
Multi - layer belt type recycling, layer by layer drying material, make full use of hot air, drying dehydration quickly, running
high efficiency, reduce energy consumption.
Working principle of Continuous Mesh Belt hot air drying machine
Materials are uniformly put on the mesh belt dryer machine by the feeder. The mesh-belt uses generally 12-60 mesh stainless steel mesh belt and it is drawn and moved inside the drier by a transmission device.
The mesh belt dryer machine is composed of several units. For each unit, the hot air is circulated separately. The water vapor will be get out from exhaust Moisture port. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and mass transfer process. This process will bring the material water away. The mesh-belt moves slowly, Running speed can be freely adjusted according to the material temperature.The final products after mesh belt dryer machine will fall into the material collector continuously.
In order to save space, the dryer can be made into multi-layer type, there are three layer, four layers, five layers, seven layers, nine layers, etc., the length of 6-40 m, effective width 0.6 2.0 m.
Application:
Equipment can be widely used in the pharmaceutical, medicine, food, agricultural products, metallurgy, building materials, chemicals, medicine, food and other industries. In recent years, multi-belt dryer hot air drying is widely used in the food industry, especially in fruits and vegetables, such as apple slices, tomato slices, potato chips, potato chips, carrots, dehydrated vegetables, etc., which is the ideal drying equipment for processing.
Multilayer belt type hot air using stainless steel mesh as a conveyor belt carrying material for continuous drying,which is the most suitable for assembly line. Since the conveyor belt is mesh type, so for drying regular or irregular variety of substance (such as: all kinds of blocks, sheets, fruits, vegetables, etc.) is most appropriate. The machine can equip with other equipment, such as washing machine, slicing machine, conveyors, sterilization machines, packaging machines matched to form an automated production line . It can also be used alone to meet user demand for dry materials processing.
Structure and features of Multi-layer type Continuous Mesh Belt hot air drying machine
Multilayer belt hot air dryer with frame, head, drying section, tail, mesh belt, gear, air intake pipe, air discharge pipe,
electrical motor, fan (hot air furnace) and other components.
Materials from feeding hole into drying chamber, slowly through for drying. Mesh belt speed according to the kinds of
material and water content can be adjusted. The wind flow using negative pressure, porous air intake to ensure effective
drying area, uniform wind velocity distribution improving the effect of drying.
