Principle:

Hot air from the entrance pipe with suitable spouting velocity from the bottom of the dryer into stirring and crushing and drying chamber, have strong shearing, blowing floating and rotating effect of material, so the material by centrifugal, shear, collision, friction and dividend micronization, strengthen the heat and mass transfer. At the bottom of the dryer, the larger and more wet particles are mechanically broken under the action of the agitator, and the particles with lower moisture content and smaller particle size are entrained by the rotating air flow, and further dried in the rising process. Because the gas-solid two-phase flow is rotating, the solid phase inertia is larger than that of the gas phase, and the relative velocity between the two phases of the solid and the gas is relatively large, and the mass transfer and heat transfer of the two phases are strengthened.

Characteristic:

The variety of feeding device for selection, feeding is continuous and stable, the process does not produce intermediate bridge phenomenon.
The dryer is arranged at the bottom of the special cooling device, avoids the material deterioration phenomenon in the high temperature zone at the bottom.
The special pneumatic sealing device and bearing cooling device, prolong the service life of the transmission part.
The wind device special -, reducing equipment resistance, and provides effective treatment of air dryer.
The drying chamber is provided with a grading ring and swirl, the fineness and final moisture adjustable. (such as calcium carbonate with moisture regulator to be less than or equal to 0.1%):
The drying chamber to high gas velocity, short residence time, effectively prevent the wall sticking of materials and heat sensitive material deterioration, high efficiency, fast Small equipment, large production.

Adaptive material:

The inorganic borate, calcium carbonate, hydroxide, copper sulfate, ferric oxide, barium carbonate, three antimony oxide, metal hydroxide, various heavy Metal salt, synthetic cryolite etc..
- organic: atrazine (pesticides), lauric acid, benzoic acid, benzoic acid, sodium oxalate, Dan, sterilization, cellulose acetate etc..
- ceramic: silica, kaolin, clay.
- anthraquinone, black oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, all kinds of azo dye intermediates.
- Food: soybean protein, starch gel, sugar, wheat starch, wheat grains.

Adaptive material:
