introduction：Working process The granular material is fed continuously and quantitatively by the feeder，The cold air is heated by the heat exchanger and enters the bottom of the fluidized bed，Penetrate the material layer through the distribution plate，Under the joint action of air flow and two high-frequency vibration motors, the material is highly dispersed and fluidized，Form a certain thickness of the fluid layer，Make sufficient heat and mass exchange between the air flow and the material，Rapid drying and dehydration，Due to the effect of vibration and the diffusion of materials，The material flows uniformly and continuously from the feed end to the discharge end of the fluidized bed，Finally, the dry material is discharged through the discharge port，Wet air is discharged from the top of the fluidized bed。
