According to the characteristics and tests of soybeans, it is recommended to use a vibrating fluidized bed dryer and a soybean dryer to design a complete production line for drying, cooling, conveying and packaging. First, the principle of vibrating fluidized bed dryer using soybean drying: The material enters the machine from the inlet of the feed. Under the action of the vibration force, the material is thrown along the fluidized bed of the horizontal plane, and moves forward continuously. The hot air passes through the fluidized bed and exchanges heat with the wet material, and the humid air is removed by the cyclone. Exhausted by exhaust 1:3. The dry material is discharged from the discharge inlet. Second, the characteristics of fluidized bed dryer: â—ŽThe vibration source is driven by vibration motor, which is stable in operation, convenient in maintenance, low in noise and long in life. â—ŽThe fluidization is well-proportioned, and there is no dead space and blow-through phenomenon, so that uniform drying and cooling of the product can be obtained. â—Ž Good adjustability, suitable for wide surface. Stepless adjustment is achieved by layer thickness and movement speed in the machine as well as full amplitude changes. â—Ž damage to the surface of the material is small. It can be used for the drying of fragile materials. When the material particles are irregular, it will not affect the working effect. â—Ž adopts a fully enclosed structure. It effectively prevents cross-infection between materials and air, and the working environment is clean. â—Ž High mechanical efficiency and thermal efficiency, good energy saving effect, energy saving 30-60% compared with general drying equipment.
