Application:
This machine is flowing and continuous type drying equipment firstly made by our factory. The machine is used for drying the piece, tape and particle state materials with good ventilation. The machine 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 also.

Principle of work
The materials are uniformly put on the mesh-belt by the material charger. The mesh-belt uses generally 12 - 60 mesh stainless steel wire net and it is drawn and moved inside the drier 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 air blower  pass through beside into low unit, after air is up and heated by steam heater,be shared by seperater, the air is spraied 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 conected 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 adjustment valve. The top and Iow circulation units can be freely equipped according to the users' demand,The unit nomber can be selected according to the demand.
