Working principle

Wet material from the feed inlet by feeder evenly on the mesh belt, mesh belt adopts 12-60 stainless steel wire mesh, moved by a drive device drag in the dryer, dryer is composed of a number of units, each unit of hot air independent circulation, by the circulation fan from external pumped and the heater heating, the lower part of the vertical blowing from the network through the air distribution plate, hot air to flow through the material layer, the water vaporization of material, air humidity, temperature, which part of the tail gas discharged by the exhaust fan, the other part of the circulating fan inlet and the outside fresh air mixing and circulation, each unit of emissions are regulating valve control, in order to make the material layer under uniform dehydration, hot air blow after blow drying material under, finally by the outside air medium or low temperature direct contact cooling, discharged from the discharge port.

DW belt type dryer is divided into: type DW ( basic), type DWD ( multi-layer belt dryer )

Characteristic

#9830; continuous drying, large batch production;

#9830; used to ventilate slice, better strip, block or granular materials drying;

#9830; for dehydrated vegetables, Chinese herbal pieces, high moisture content, and temperature of the material does not allow a high material is particularly suitable for;

#9830; of dehydration on the cake, drying can be made to granulation or bar;

#9830; fast drying, evaporation of high intensity, good product quality;
