The spray dryer is one of the continuous atmospheric dryers. The liquid material is sprayed with a special device to form a mist, and is dried in contact with hot air. For the drying of some heat-sensitive liquids, suspensions and viscous liquids, such as milk, eggs, tannins and drugs. Also used for drying fuels, intermediates, soap powder and inorganic salts.
Rotary Atomizer Spray Dryer Price Application
Food and plants: oats, chicken juice, coffee, instant tea, seasoning spices meat, protein, soybeans, peanut protein, hydrolysates, and so on.
Carbohydrates: corn steep liquor, corn starch, glucose, pectin, maltose, potassium sorbate, and the like. Chemical industry: battery raw materials, basic dye pigments, dye intermediates, fertilizer, formaldehyde silicic acid, catalysts, agents, amino acids, silica, and so on.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, and so on.
Rotary Atomizer Type Spray Dryer Working Principle
The air is filtered and heated into the top of the dryer air distributor, hot air into the spiral evenly into the drying chamber. The material liquid is sprayed into a fine atomized liquid droplet through the high-speed centrifugal nebulizer at the top of the tower body, and can be contacted with the hot air in a very short time and can be dried into finished products. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is drained by the draft fan.
Rotary Atomizer Spray Dryer Feature
* High drying efficiency
* The finished power or granule has good homogeneity, fluidity and solubility.
* Simple and convenient operation
* Mechanical atomizer is adopted, and driven by gear, speed is stable, which make sure the fogdrop is uniform.
* The direction and angle of hot air distributor is adjustable, which ensure the fogdrop fully contact hot air. .
* Conjunction elbow is made of sanitary degree steel pipe, smooth enough to avoide matereial blocked inside the pipe.
* Wide application: food, chemicals, ceramics, basic dyestuff, etc.
Why choose the centrifugal spray dryer to drying ?
The drying speed is fast and the surface area of the liquid is greatly increased after atomization. In the hot air flow, 95% -98% moisture can be evaporated instantly. The drying time is only a few seconds, which is especially suitable for the drying of thermos-sensitive materials.
The product has good uniformity, fluidity and solubility, high purity and good quality.
Simplified production process, easy operation and control. For 40-60% moisture content (special materials up to 90%) liquid can be dried into powder products, control and management are very convenient.
