Description
Belt dryer for Seaweed 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.
Working Principle：
The series of hemp dryers are processed by using a multi-layer mobile stainless steel mesh belt or vibrating plate. The hot air flows through the mesh belt and the material layer from bottom to top. The heat exchange is uniform, sufficient, and the production efficiency is high. Good, with a cooling layer and rotary conveying device, low discharge temperature, which is convenient for timely packaging. The lifting device with the screed is used, the thickness of the material is uniform, and the thickness of the material layer can be adjusted steplessly. The material area is from 25m² to 70m², with five different sizes, which can meet the needs of various materials and different production scales.
