DWC Multilayer Conveyor Dryer Machine

DWC Multilayer Conveyor Dryer Machine

Description
DWC multilayer 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.

Application
DWC series multilayer belt dryers are extensively used for dehydrating and drying the sheet type, stripe type and granular materials in the industries of food, agricultural products, dehydrated vegetables, Chinese medicinal materials, seafood, native products, feed and chemical materials.

Material Movement and Process Diagram
This conveyor dryer adopts five-layer structure. Materials in the hopper are lifted to the top layer by conveyor belt, and then enter into the drying machine. The materials with the upper belt move to the other end of the multilayer belt dryer, and then slide along the hoop plate down to the next layer. And then the materials along with this layer pass through the conveyor dryer to the other end, and fall to the lowest layer, and so on. The materials along with the lowest belt move to the other end of the drying machine to discharge. (See the graph below)

Features of Multilayer Belt Dryer
1.The hot gas flow passes through the mesh belt and the material layer from bottom to top, thus ensuring uniform heat transfer. This drying machine has high production efficiency and good quality.
2.This multilayer conveyor dryer adopts hoisting equipment with uniform feeder, and the thickness of the material layer can be infinitely variable control.
