Working Principle

The materials are uniformly put on the mesh-belt by the material charge,the mesh-belt uses generally 12-60 mesh stainless steel wire net and it is drawn and moved inside the dryer by a transmission device.The dryer is composed of several units.For each unit,the hot air is circulated separately.In the first unit,air out from circutation air blowerpass through mesh-belt in to top of machine.The drying process is hot air passes through the mesh-belt covered with a special moisture from the top to the bottom or from the bottom to the top,and this will complete the heat and mass transfer process.The air pipe of the top is connected with fan,one part of air is circulated,some exhausted gas is discharged with a special moisture eilmination blower,and other waste gas is controlled through an adjuestment value.The top and low circulation units can be freely equipped according to the users’ demand,the unit number can be selected according to the demand.

Scope of application

DWT series mesh-belt dryer is flowing and continuous type drying equipment firstly made by our factory.It is used for drying the piece,tape and granular  materials with good ventilation.It is suitable for the materials,such as de-watering vegetable,herbal medicine of traditional Chinese medicine and others,for which the water content rate is high and the high temperature is not allowed.The machine owns the advantages that its drying speed is fast,the evaporation strength is high and the product quality is good.The de-watering filtering cake state paste material after the particle making or bar making can be dried too.
