The main role and combination requirements of rotary flash vaporization dryer

- Jun 18, 2019-

The hot air tangent of the rotary flash vaporization dryer enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating paddle, the material is dispersed under the action of impact, friction and shear stress. The block material is rapidly pulverized, fully contacted with hot air, and heated. dry.

The dry material of the rotary flash vaporization dryer rises with the hot air flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring to the outside of the dryer, and are recovered by the cyclone and the dust collector, and the dry or bulk material is collected. The wall is deflected by the centrifugal force and re-grown to the bottom to be pulverized and dried.

Rotary flash vaporization dryer features

1. Applicable paste and filter cake drying;

2, the equipment is small, is the same production capacity spray drying equipment volume of about 1/4;

3, short drying time, especially suitable for heat sensitive materials;

4. The device body has no stick wall phenomenon;

5. Compared with the box drying method, it can save energy by 30~50% without pulverizing after drying;

6, closed operation, no pollution to the environment.

7. The organic combination of swirling, fluidizing, spraying and crushing and grading techniques.
