Working Principle: 

ZLG Vibrating Fluid Bed Dryer is a type of fluidized bed where the mechanical vibration enhances the performance of fluidization. VFBD has been widely used for drying or cooling granular materials (0.5-3mm) in various industries. 

Wet material is gravity fed onto the fluid bed (normally a perforated plate) via the infeed hopper, the strong vibration of dryer body fluidizes the wet material which moves towards the discharging vent. At the same time, hot air is evenly distributed into the bottom drying chamber and flows though the perforated plate. Moisture is rapidly evaporated with complete contact and heat transfer between hot air and well fluidized wet material and sucked out by the draft fan.The drying process is continuous and cooling air can be introduced to cool the product to required temperature. 

Technical Features: 

• Wide application: VFBD is successfully used on all types of powders, agglomerates, granules, especially those which fluidize poorly due to a broad particle size distribution. The fluid bed can be operated as a single drying or cooling unit - often associated with a spray drying system. 
• Energy-saving: Due to strong mechanical vibration, wet material can be perfectly fluidized and move forward with slow air flow velocity. Energy consumption is much lower than normal fluid bed dryer. 
• Flexibility in heat source: The heat source can be steam, electricity, thermal oil, oil/gas/biomass fired hot air generator to cater for different working conditions.
• Drying time adjustable: The residence time of wet material inside the drying chamber is adjustable by regulating the angle of vibration motors to satisfy different drying requirements in moisture.
