XSG series rotary flash dryer
Working principle of XSG series rotary flash dryer:The hot air enters the bottom of the dryer at a suitable spouting speed from the inlet pipe, and enters the stirring crushing drying chamber, which has strong shearing, blowing and rotating effects on the materials. Therefore, the materials are micronized by centrifugation, shearing, collision and friction, thus enhancing 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.
XSG series rotary flash dryer features:
Because of the high dispersion of the material and the high relative velocity between gas and solid, the heat and mass transfer are strengthened, which makes the production intensity of the machine high.
1. The dry gas enters the bottom of the dryer and produces a 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.
2. In the high temperature area at the bottom of the dryer, the heat sensitive material does not contact with the hot surface directly, which solves the problem of coking discoloration of heat sensitive materials.
3. Due to the high circumferential gas velocity in the drying chamber and the short residence time of materials, the high efficiency, fast and small equipment mass production is achieved.
4. In order to control the moisture content of the material to a very low level, the rotary flow sheet is placed in the drying chamber.
5. The upper part of the dryer can control the particle size and humidity of the outlet materials.
