It effectively removes moisture from wet materials through vibration and fluidization to achieve the purpose of drying. Vibrating fluidized bed dryer, referred to as vibrating fluidized bed, is a new type of drying device that applies a vibration source with specific requirements to an ordinary fluidized bed dryer. It fluidizes the material in the bed layer through vibration and exchanges heat with hot air to achieve drying. After the material enters the machine from the feed port, it is continuously thrown forward in the horizontal direction under the action of vibration force.
