Calcium Carbonate Spin Flash Drying Equipment Benzoic Acid Spin Flash Drying Equipment Wheat Sugar Drying Equipment

working principle :

The hot air enters the stirring, pulverizing and drying chamber from the bottom of the dryer through the inlet pipe at a suitable jet speed, and produces strong shearing, blowing, and rotating effects on the material, so the material is subjected to centrifugation, shearing, collision, and friction to be micronized. , which enhances mass and heat transfer. At the bottom of the dryer, the larger and wetter granules are mechanically broken up under the action of the agitator, and the granules with lower moisture content and smaller particle size are entrained by the rotating airflow to rise, and are further dried during the rising process. Because the gas-solid two phases are rotating, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the two phases of the solid and gas is relatively large, which strengthens the mass transfer and heat transfer between the two phases, so the machine has high production strength.

Overview:

XZG series spin flash dryer is a new type of drying equipment successfully developed by our factory on the basis of introducing and absorbing foreign advanced technology. It is suitable for drying block, paste and certain viscous materials into powder products. The machine has advanced technology, reasonable design, compact structure, wide application range, large production capacity, good product quality, high efficiency and energy saving. Advanced technology in the 1980s.

Applicable materials:

1. Inorganic: boric acid, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various metal hydroxides, various heavy metal salts, synthetic cryolite, etc.;

2. Organic substances; atrazine (pesticides and insecticides), lauric acid, benzoic acid, benzoic acid, bactericide, sodium oxalate, cellulose acetate, etc.;

3. Ceramics: kaolin, silica, clay;

4. Dyes: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, various azo dye intermediates;

5. Foods: soybean protein, gelatinized starch, distiller's grains, wheat sugar, wheat starch, etc.

Features :

1. A variety of feeding devices are available for selection, the feeding is continuous and stable, and there is no bridging phenomenon in the process.

2. A special cooling device is set at the bottom of the dryer to avoid the material being in the high temperature area at the bottom

produce metamorphism.

3. Special air pressure sealing device and bearing cooling device can effectively prolong the service life of the transmission part.

4. The special air distribution device reduces the resistance of the equipment and effectively provides

Handling air volume.

5. The drying chamber is equipped with a grading ring and a swirl sheet, and the material fineness and final moisture can be adjusted. (Such as

The final water content of calcium carbonate can be adjusted to ≤0.1%)

6. Compared with other drying methods, it can effectively increase the specific gravity of the material.

7. The circumferential air velocity in the drying room is high, and the material residence time is short, which can effectively prevent the material from sticking to the wall

And heat-sensitive material deterioration phenomenon, to achieve high efficiency, fast, small equipment, large production.
