The flash drying machine is a new type of drying equipment developed by our factory on the basis of introducing and absorbing advanced foreign technology. It boasts advanced technology, reasonable design, compact structure, wide application range, high production capacity, excellent product quality, high efficiency, energy-saving, and completes drying, crushing, and sieving in one machine, eliminating environmental pollution. The overall performance of the machine reaches the international advanced technological level.

Principle of Flash Vapor Drying Machine

Hot air enters the mixing and crushing drying chamber from the bottom of the dryer through the inlet pipe at an appropriate jet speed; it exerts strong shearing, blowing, and rotating forces on the material; the material is micronized through centrifugal force, shearing, collision, and friction; and enhances mass and heat transfer. At the bottom of the dryer, larger and wetter particle clusters are mechanically broken by the mixer; particles with lower moisture content and smaller particle size are carried upward by the swirling air stream, further drying as they rise. Due to the rotational flow of the gas-solid phases; the inertia of the solid phase is greater than that of the gas phase; the relative velocity between the solid and gas phases is high; thus, the mass and heat transfer between the two phases is enhanced, resulting in high production intensity of the machine.
