CE Tunnel Belt Industrial Betaine Microwave Dryer
|Place of Origin:|
Belt dryer is specially designed for drying different shapes of root vegetables and leafy vegetables. This drying machine has three-layer and five-layer structure, each layer can be independently adjusted the drying temperature according to the characteristics of the materials.
The working principle of this multilayer conveyor dryer shows as follows: the material is limit controlled by the hopper and is evenly spread on the mesh belt. The materials are driven by the motor to the top layer, then perform uniform motion in the multilayer belt dryer and conduct downward movement layer by layer. Cold air enters from the two axial flow fans, after ballasting via baffle plate, it will flows from bottom to top. There is equipped with a heater under the mesh belt at each layer. The cold air is constantly gradient heated, and then through the material layer. It will conduct mass transfer and heat transfer with the material layer, so that the moisture contained in the material can be rapidly vaporized and evaporated. When the cold air gets to the top layer, it has become saturated moist air, and will be discharged outdoors under the action of exhaust fan
1.The fluidization is uniform and stable, no dead bed and blow through phenomenon, and the drying and cooling materials are uniform:
2.Adjustability, material thickness, residence time and amplitude can be adjusted properly:
3.The damage to the surface of the material is small and can be used for drying of fragile materials:
4.High mechanical efficiency and thermal efficiency, energy saving 30%-60% compared with the drying device;
5.The parts in contact with the materials are clean and can be continuously produced.
