Spray dryer

The closed-loop spray drying system uses an inert gas (generally N2) as the carrier to transfer heat, used in a in a closed cycle. it is beneficial for conserving the heat carrier, recovering organic solvents, preventing atmospheric pollution from toxic substances, and avoiding material oxidation.

- GMP-compliant design; drying air cleanliness better than Class 100,000, quick-clean surfaces, consistently stable product quality.
- Ultra-fast drying: after atomization the droplet surface multiplies, so 95–98% of moisture evaporates within 5–40 s in the high-temperature airflow.

Upgraded from standard open-cycle equipment with inner-wall sweeping, jacket cooling, and cold-air feeding, this multi-functional spray dryer offers superior adaptability to complex materials. It is ideal for drying heat-melting and high-viscosity substances, making it a versatile solution for the pharmaceutical, food, and chemical sectors.

Centrifugal spray dryer is an air distributor on the top of the drying tower after fresh air is heated into clean hot air through the air
inlet filter and heater, and the hot air enters the drying tower evenly in a spiral shape. The feed fluid is conveyed to the centrifugal
spray or pressure nozzle at the top of the drying tower by the supply pump, and the rotating spray is formed into extremely fine
atomized droplets, which are in contact with the hot air in the downstream, and the moisture evaporates rapidly, and is dried into
finished products in an extremely short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust air is vented after being purified by the dedusting system.
