The working principle and application field of spray dryer

working principle:

After filtering and heating, the air enters the air distributor on the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The material liquid passes through the high-speed centrifugal atomizer at the top of the tower body, and (rotating) sprays into very fine misty liquid beads, which can be dried into finished products in a very short time in cocurrent contact with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is evacuated by the induced draft fan.

Application areas:

1. Chemical industry: battery raw materials, basic dyes and pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, white carbon black, etc.

2. Plastic resin: AB, ABS emulsion, urinary formaldehyde resin, phenolic resin, dense rubber (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.

3. Food industry: fat-rich milk powder, cocoa milk powder, milk substitute powder, animal blood powder, egg white (yellow) whole egg powder, etc.

4. Food and plants: oatmeal, chicken juice, coffee, instant tea, flavored meat, protein, soybean, peanut protein, hydrolysate, etc.

5. Sugars: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.

6. Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.
