High Speed Centrifugal Spray Dryer Ceramic Powder Drying Equipment
High Speed Centrifugal Spray Dryer
Introduction
Scope of application
Centrifuge spray dryer is a kind of continuous atmospheric
dryer.Use pneumatic or electric atomization device to make liquid
high-speed centrifugal spray as fog droplet, make these fog droplet
contact with the hot air in the drying chamber and instantaneous
drying.
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.

Characteristic
1.Stainless steel material, arc corner design and polyester powder
coated shell, prevents corrosion of acidity and alkaline air
effectively.
2. Imported Schneider electrical components which is more
stability.
3. PLC control system, make your research more easier and
efficient.
4. Build in oil-free air compressor, without any noise.
5. Self-priming peristaltic pump, avoid secondary pollution, make
sure whole process conducted steady and smoothly.
6. Narrow size distribution, more than 95% of the dry powders are
in the same range of particles.
7. Innovative tower wall purging device, improves the material
recycling rate.
8. High speed of drying, after spraying of the material liquid, the
surface area of material will be increased greatly, make your
research more efficient.
9. In the hot-air flow, 95%~98% of water can be evaporated at a
moment. You can finish material drying only in several seconds.
10. Especially suitable for drying the heat sensitive materials,
after drying, there's no need for smashing and sorting, so as to
reduce the operation procedures and save your time.
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.
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.
