Introduction
The spray machine for drying is the technology most widely used in
the liquid technology shaping and in the drying industry. The
drying technology is the most suitable for producing solid powder
or particle products from liquid materials, such as: solvent,
emulsion, suspension and pumpable paste states, fro this reason,
when the particle size and distribution of the final products,
residual water contents. Mass density and the particle shape must
meet the precise standard, spray drying is one of the most desired
technology.
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.

Product Features
1. Rapid drying speed, which just takes 5-15 seconds.
2. Suitable for thermo-sensitive material and keep the origin
state.
3. Simple processing and easy operation, which is suitable for
continuous production.
4. The product has a good degree of uniformity, liquidity and
dissolubility with high quality and purity.
5. Can adjust the product diameter, density and water content in
some degree which is convenient to control and manage.
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 finely 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.
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.
