This machines is suitable for granulating for powder in container by spray binder.
The principle of action is based on: Put the powder material into the fluid bed. The cold air is drawn into the fluid bed through the pre, middle and final filters(HEPA) and passes through the heating chamber behind the main machine, heated to the desired temperature by the heater. The material is fluidized in the fluid bed regularly . The binder is delivered to the nozzle by the liquid pump, which is sprayed to the fluidized material after being sheared into droplets by air.
The evaporating moisture is drawn out by the fan.

fluidized bed dryers

1. In-situ Vacuum Freeze Dryer: Features simple operation and excellent drying performance. By integrating pre-freezing and drying processes, it fundamentally eliminates contamination risks, ensuring high process consistency and superior product quality.

2. Aerospace-grade aluminum alloy baffle material: Adopts contact heating, with outstanding thermal conductivity, lightweight, high strength and corrosion resistance. It is an ideal choice for efficient and uniform freeze-drying.

3. Efficient mixed refrigerant medium, low freezing point and high boiling point, high heat exchange efficiency and long service life.

4. The drying curve optimization control algorithm can control the heating rate and vacuum value of the product during the drying stage.

5. Professional gas diversion design and control technology, strong water catch ability and high drying efficiency
