Applications
DW mesh-belt dryer is continuous dryer for large production.lt is usedfor drying sheet materials,bar masterials granules materials thathave good air permeability. As to dehydrated vegetable Chineseherb pieces which have high moisture and need low dryingtemperature,DWT belt dryer is specially suitable.
Principle of work
The materials are uniformly put on the mesh-belt by the material charger. The mesh-belt used generally 12-60 mesh stainless steel wire net and it is drewn and moved inside the driver by a transmission device. The drier is composed of several units.For each unit,the hot air is circulated separately. In the first unit,air out from circutation sir blower(5)pass through beside into low unit,after air is up and heated by steam heater(4), be shared by seperater(3), the air is spraies through mesh-belt in to top of machine. The drying process is hot air passes through the mesh-belt covered with asprcial moisture from the top to the bottom of from the bottom to the top, and this will complete the heat and mass transfer process. The air pipe of the top is conected with fan, one part of air is circulated, some exhausted gas is discharged with a spesial moisture eilmination blower,and other waste gas is control I es through an adjutment eilmination blower,and other waste gas is controlles through an adjustment valve. The top and low circulation units can be freely equipped according to the usersi demand, The unit number can be selected according to the demand.
