Abstract : vibrating fluidized bed dryer work, from the vibration of the electrical excitation and making materials in the air distribution plate leap forward the same time, and distribution of the bottom plate into contact with hot air, heat and mass transfer. Box under the bed to provide a stable with some pressure on the Wind Room. Fan regulation, which box on the bed material to maintain the upper-vacuum, maintain good dry environment and prevent dust leakage. Air distribution plate support materials make hot air evenly distributed. Vibration fluidized bed design method is not perfect, could not be done strictly in accordance with the specific materials heat and mass transfer model to design dryer, engineering experience in the design still occupy important positions. Usually, the use of conventional heat balance calculations with the necessary tests to determine bed area; use vibration theory vibration system design; Vibration waste heat recovery using fluidized bed drying, Therefore, the design of heat pipe air preheater, clean air heated to 100 degrees Celsius to dry materials. This measure is well for saving energy consumption.
