XSG Rotary Flash Dryer
Time：2018.03.21
Rotary flash dryer is an utility model patent product. The machine is a typical fluidized dryer, which not only achieves continuous operation of dynamic drying, but also overcomes the disadvantages of low static heat efficiency, high labor intensity, environmental pollution, and serious waste, so that chemical products can be effectively realized in the drying unit. The perfect unity of quality, efficiency and environment.
The rotary flash dryer has advanced technology, reasonable design, beautiful appearance and compact structure. The successful launch of this machine was quickly recognized and promoted by the industries such as pesticides, dyes, pigments, fine chemicals, feed, and additives, and it was highly praised by the users.
Operating Principle of XSG Rotary Flash Dryer
The heated (or dehumidified) air enters the stirring and crushing drying chamber at the appropriate spraying speed from the bottom of the dryer, and the material is subjected to strong shearing, blowing and rotating effects, so the material is subjected to centrifugal, shear, collision, and friction. It is micronized to form a large specific surface area and enhances mass transfer and heat transfer. At the bottom of the drying chamber, the larger and moister pellets are broken mechanically by the stirrer. The particles with lower moisture content and smaller particle size are entrained by the swirling airflow, further dried during the ascent, and classified.

XSG Rotary Flash Dryer Features
1. Drying of viscous material: The conical structure of the dryer, the erosion of the wall of the gas flow counter, and the structure of the stirrer determine the ability to handle certain viscous materials.
2. Dry heat-sensitive material: Due to the short drying time, the relative speed of the material and hot air is large, and the hottest air does not directly contact with the dried material, so it is suitable for handling heat-sensitive materials.
3. High drying strength: As the materials are broken, washed, and collided in the drying process, the surface area increases, and the drying is strengthened. At the same time, since the hottest air does not directly contact the dried material, the inlet air temperature can be higher than the melting point of the material. Therefore, XZG Rotary flash dryer has high drying strength.
4. Effectively control the final moisture content and fineness: Through the setting of built-in components (swirling sheet, ceramic analysis ring or classifier) in the drying tower, and the unified coordination with the temperature of the inlet and outlet air, the final moisture and finished fineness can be effectively controlled.
5.Environmental compliance: The system operates under micro-pressure to eliminate the pollution of the operating environment, and uses different dust removal methods and dust removal materials according to different materials (pulse bag type dust collector, water bath dust collector, venturi wet dust collector, etc.).
6. Drying of viscous material: According to different materials, the feeder and discharger take different forms to achieve the purpose of automatic, continuous feeding and smooth discharging.
7. Best power matching: According to different material properties (density, bulk density, viscosity, fineness, initial moisture, final moisture, angle of repose, etc.), blowers, induced draft fans, stirrers, feeders and other equipment are best equipped power.
