Professional Continuous vacuum tray dryer Fluid Bed Dryer machine

Working Principle

The material is placed on the conveyor belt, through the switch-plate device on the conveyor belt, spread the belt evenly, the material through the first layer transition to the next layer, each layer set guide material device and rollover device. make the material fully contact with the heating medium, dried material will be discharged by the last layer.

The heating medium enters into the dryer machine by the fan, wind speed induced draft fan-generated pressure to make adequate and uniform spread in the dryer at the bottom of the heating medium, since the lower pressure is greater than the above pressure, the upward movement of the heating medium through each belt, so that the material in contact with the heat medium sufficiently, improve drying efficiency.

Technical features:

1. Under vacuum, the material solution boiling point decreases,and the heat transfer driving force increases, so that heat transfer area of the evaporator can be saved.

2.The heat source for evaporation can be low pressure steam or waste heat steam.

3. The evaporator heat loss is low.

4. The machine can carry out sterilization before drying, and does not have any impurities during drying, conforming to GMP requirements.

5. The machine is a static vacuum dryer. Therefore, the shape of dried materials will not be damaged.
