Introduction & Applications :-  RAVI – Continuous Fluidized Bed Dryer is a kind of intensified drying device with special purpose. It is usually used for the final drying of materials. As the material fluidization is assisted by mechanical vibration in the drying process, it is not only beneficial to the boundary layer turbulence and the enhancement of heat and mass transfer, but also ensures the drying equipment to work under the relatively stable flow mechanical conditions. This equipment has a good drying function, but also according to the needs of the process with material cooling, screening and conveying processes.

RAVI – Continuous Fluidized Bed Dryer is designed for continuous drying of non-sticky particles. Cold air is filtered, heated, and then distributed through the bed’s perforated plate, flowing upwards. Materials enter the bed via a screw feeder or belt Conveyor, move forward due to vibration (vibrating motor to produce excitation force to make the machine vibrate), the material jumps forward under the action of this excitation force in the given direction, while the hot air is input at the bottom of the bed to make the material in fluidized state, the material particles are in full contact with the hot air and carry out intense heat and mass transfer process, at this time the highest thermal efficiency. The upper cavity is in the state of micro-negative pressure, the wet air is led out by the induced fan, and the dry material is discharged from the discharge port, so as to achieve the ideal drying effect. If cold air or wet air is sent to the bottom of the bed, it can achieve cooling and humidifying effect. These dryers are utilized for drying, cooling, and humidifying powders in industries such as pharmaceutical, bulk drug, chemical, food, fertilizer, plastic, grain and oil, slag, salt, and sugar.
