Calcium chloride is a common desiccant. As an important chemical product, it has been widely used in industry, food processing industry and medicine. Calcium chloride is a colorless cubic crystal. The general product is white or white porous block or granular, honeycomb shape. It has strong hygroscopicity and is easily deliquescent when exposed to the air and easily soluble in water. The flash dryer is a kind of drying equipment dedicated to calcium chloride. Through drying, sodium chloride is more widely used. The following is an introduction to the working principle of the calcium chloride flash dryer.
The working principle of calcium chloride flash dryer
The hot air enters the stirring, crushing and drying chamber from the bottom of the dryer at a suitable spouting speed from the inlet pipe, and produces strong shearing, floating, and rotating effects on the calcium chloride, so calcium chloride subjected to centrifugation, shear, collision, friction and particulate, enhanced mass transfer and heat transfer. At the bottom of the dryer, the larger and wetter particle clusters 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 airflow to rise, and are further dried during the ascent. Because the gas-solid two phases make a rotating flow, the inertia of the solid phase is greater than that of the gas phase, and the relative speed between the solid and gas phases is relatively large, which strengthens the mass and heat transfer between the two phases, so the machine has high production intensity.
Flash drying can not only dry calcium chloride, but also dry inorganic, organic, ceramic, dye, food and other products, with a wide range of uses.
Inorganic: boric acid, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various metal hydroxides, various heavy metal salts, synthetic cryolite, etc.
Organic matter: Atrazine (pesticides), lauric acid, benzoic acid, benzoic acid, bactericide, sodium oxalate, cellulose acetate, etc.
Ceramics: kaolin, silica, clay.
Dyestuffs: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, various azo dye intermediates.
Foods: soy protein, gelatinized starch, distiller's grains, wheat sugar, wheat starch.
