Design of Vibrating Fluidized Bed Dryer for Tea

Vibration fluidized bed is widely used in sugar refining，plastics，dairy products，medicine，chemical fertilizer，chemical industry，salt industry and metallurgy industry as well as in the area of drying for its characteristics of uniform fluidization，good drying effect，energy saving and so on.But it is rarely applied in drying tea.Based on this phenomenon，basic physical and mechanical properties of tea were determined.A vibration fluidized bed dryer for tea was designed.Selection of motor and its installation angle were designed.Spring and other parts were designed.Required air quantity and heat quantity were calculated.Three-dimensional diagram was drawn by Solidworks software，two-dimensional diagram was drawn by CAD software.Inherent frequencies and modal shape of the first 10 steps of the vibration dryer were obtained by modal analysis of wind plate based on ANSYS software.Results showed that operating frequency of vibration dryer could avoid natural frequency and avert resonance with a good vibration isolation effect at the same time.Prototype met the requirements of production.
