原理

物料由加料器均勻地鋪在網帶上，網帶一般采用12-60目不銹鋼絲網，由傳動裝置拖動在干燥機內移動。干燥機由若干單位組成，每一單元熱風獨立循環，部分尾氣由專門排濕風機排出，廢氣由調節閥控制，熱氣由下往上或由上往下穿過鋪滿物料的網帶完成熱量與質量傳遞的進程，帶走物料水份。網帶緩慢移動，運行速度可根據物料溫度自由調節，干燥后的成品連續落入收料器中。上下循環單元根據用戶需要可靈活配備，單元數量可根據需要選取。

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.
