Spray drying is a widely applicable drying technology. It can rapidly convert solutions, emulsions, suspensions, or pastes of liquid raw materials into powdered or granular products. If you have requirements regarding the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product, please feel free to contact us regarding our centrifugal spray dryer.

Centrifugal Spray Dryer Working Principle
First, the air is purified by a filtration system, then heated by a heater, and subsequently enters the air distributor at the top of the dryer.
Second, the hot air enters the drying chamber in a spiral pattern, creating a stable hot air environment within the tower.
Then, the liquid feed is pumped to a high-speed centrifugal atomizer at the top of the tower, where it is dispersed into fine mist droplets by high-speed rotation.
Finally, these droplets flow in parallel with the hot air, evaporating the moisture in a short time to ultimately form a dried powder or granular product.
This equipment consists of an air filter, blower, heater, raw material tank, feed pump, atomizer, drying tower, primary cyclone separator, secondary dust collector, induced draft fan, and wet scrubbing system.
Air filter: Ensures clean air entering the system.
Blower: Responsible for delivering air.
Heater: Can be electric, steam, fuel oil, natural gas, or coal-fired.
Raw material tank and feed pump: Ensure liquid materials enter the atomization system.
Drying tower: Completes heat exchange and moisture evaporation.
Cyclone separator and bag filter: Used for powder collection and exhaust gas dust removal.
Atomization: Small-scale equipment uses compressed air drive, while medium and large-scale equipment uses mechanical drive. Rotation speed varies from 8000 to 25000 RPM.
Dry powder recovery rate: The ratio is typically ≥95%, which can reduce material loss and improve economic efficiency.
Drying speed: After the liquid is atomized, the surface area increases. 95%-98% of the moisture can be evaporated instantly, making it suitable for heat-sensitive materials.
Production process: Liquids with a moisture content of 40-60% can be dried into powder products in a single step, without the need for crushing and screening.
