polyester woven dryer screen

Product Description:

The mesh belt dryer is conceptually very simple. The product is carried through the dryer on conveyors and hot air is forced through the bed of product. It is often described as simply a conveyor in a box with hot air. The reality, however, is that the belt dryer is one of the most versatile dryers available. Few drying technologies can match the belt dryer’s ability to handle such a wide range of products.  Products, as varied in composition, shape, and size as coated breakfast cereals, nuts, animal feed, charcoal briquettes, and rubber, can be dried in a  conveyor dryer.

Principle

The materials are evenly spread on the mesh belt by the feeder. The mesh belt is generally made of stainless steel screen of 12-60 meshes and moves in the dryer after driven by the transmission device. The dryer is composed of several units. The hot air in each unit circulates separately. Some tail gases are discharged by the special dehumidifying fan, and waste gases are controlled by the control valve. The hot air goes through the mesh belt spread with materials from the bottom to the top or from the top to the bottom to complete the process of heat and mass transfer and bring away moisture of materials. The mesh belt will move slowly. Its running speed can be freely adjusted according to material temperature. The finished products after drying will drop into the material collector continuously. The upper and lower circulation units can be set flexibly according to user needs. The unit quantity can be decided according to the needs.
