LPG Centrifugal Spray Dryer

LPG Centrifugal Spray Dryer

After filtering and heating, the air enters into the hot air distributor at the top of the centrifugal spray dryer, and the hot air will spirally and evenly goes into the drying chamber. The material liquid via high-speed centrifugal atomizer rotates into extremely thin vaporific liquid globule and parallelly flows with the hot air, and then the liquid will be dried into powdery products in a very short time (5-10 seconds). The waste gas after filtering will be expelled through the fan. For the wet organic solvent materials, the spray drying machine can be designed with closed cycle process. It can utilize cyclic nitrogen to dry the materials.

LPG high-speed centrifugal spray dryer is a kind of dedicated equipment for drying emulsion, suspension, paste and solution. This spray drying machine is particularly prominent in drying polymers, resins, dyes, pigments, ceramics, glass, rust remover, pesticides, carbohydrate, dairy products, detergents, fertilizer, organic compounds and inorganic compound liquids. Specifically, this centrifugal spray dryer is applied to the following fields:
1. Chemical Industry
Potassium chloride (sodium chloride), alkaline dye and pigment, dye intermediate, compound fertilizer, formaldehyde silicic acid, catalyst, sulfuric acid agent, amino acid and white carbon black.
2. Plastic Resin
AB, ABS emulsion, urea resin, phenolic resin, polyethylene, polyvinyl chloride, etc.
3. Food Industry
Rich fat milk, cocoa milk powder, milk replacer, pig blood powder and egg white (yolk)
4. Food and Plant
Oat, chicken liquid, coffee, instant tea, flavoring meat, protein, soybean, peanut protein and hydrolysate
5. Carbohydrate
Corn steep liquor, corn starch, glucose, pectin, malt sugar, potassium sorbate and so on

Features of Spray Drying Machine
1.LPG centrifugal spray dryer with fast drying speed can constantly evaporate 95%-98% moisture. The drying time is about 5 seconds to 15 seconds. This drying equipment is especially suitable for thermosensitive substance.
2.This spray dryer has excellent uniformity, liquidity and solubility as well as high purity.
3.This spray drying machine has simple production process and easy operation. After drying, it does not need to grind and screen, which can reduce production procedure and enhance the purity.
