A:Multi-layer A:Multilayer belt type hot air dryer principle:
Is a kind of batch, continuous production.The main heating mode are electric heating and steam heating.Its main principle is to put the material evenly spread in net, net belt with 12-60 steel mesh belt, reciprocate by dragging gear in dryer, hot air between the material flows and water vapor from moisture discharge hole, so as to achieve the purpose of drying.The cabinet length is made up by the standard section, in order to save space.The dryer can be made into multi-layer type, there are two chambers three layers , two chambers five layers, length : 6-40 m, effective width :0.6-3.0 m.
B:Multilayer belt type hot air dryer usage :
Widely used in metallurgy, building materials, ceramics, organic fertilizer, chemical and other industries, and the ideal equipment for food and vegetables drying processing.Multilayer belt type hot air dryer is used of steel net work as a transport carrier material for continuous drying equipment, the most suitable for flow operation.Due to the conveyor is a mesh, so drying rules or irregular various substance is the most appropriate (such as :coal, ore forming block, food, vegetables, etc.) .This machine not only can be used with other equipment,but also used alone.
C:Multilayer belt type hot air dryer structure and features:
Multilayer belt type hot air dryers has head, drying section, tail, mesh belt, transmission device, air inlet pipe, air discharge pipe, fan (hot air source ) etc. Material is from head into chamber slowly drying by drying, mesh belt speed depending on the kinds and moisture content of the material.The wind flow adapt negative pressure , porous air intake to ensure effective drying area.Wind speed distribution uniform ,which improve the effect of drying.
To get the best drying effect and appropriate yield, moisture content of materials, wire mesh belt speed and the wind temperature must be appropriate reasonable, and organic combination.
