QSG rotary flash dryer

working principle:

Hot air enters the bottom of the dryer through the inlet pipe at a suitable spouting speed, and enters the stirring crushing drying chamber, which has strong shearing, blowing and rotating effects on the materials. Therefore, the materials are granulated by centrifugation, shearing, collision and friction, which strengthens the mass and heat transfer. At the bottom of the dryer, the larger and wetter particles are mechanically broken under the action of the agitator. The particles with lower moisture content and smaller particle size are entrained by the rotating airflow and further dried in the rising process. Due to the rotating flow of gas and solid, the inertia of solid phase is greater than that of gas phase, and the relative velocity of solid phase and gas phase is larger, so heat and mass transfer between two phases are strengthened, so the production intensity of this machine is high.

QSG rotary flash dryer features:

The drying gas enters the bottom of the dryer and produces strong rotating air flow, which has a strong scouring effect on the materials on the wall of the dryer and eliminates the wall sticking phenomenon.

In the high temperature area at the bottom of the dryer, the heat sensitive materials do not directly contact with the hot surface, which solves the problem of coking discoloration of heat sensitive materials.

Due to the high circumferential gas velocity in drying chamber and short residence time of materials, it can achieve high efficiency, fast and large-scale production with small equipment.
