China LPG Series High-Speed Centrifuge Spray Dryer - Top Suppliers and Factory for Instant Drying Solutions
Principle
After fresh air is filtered and heated, it enters into the air distributor which on the top of the dryer. The hot air in spiral form equably enters into the drying room. When liquid raw material are passed through the high-speed centrifugal sprayer on the top of the tower, it will be rotated and sprayed into the extreme slim mist liquid beads. Raw material can be dried to the final products instantly while it contact with the heated air. Finished products are discharged continuously from bottom of the drying tower and cyclones separator. Wasted air is discharged from blower.
Applications
Fast drying speed:
after spraying into small drops, contacting area greatly increased. So when these small drops contact with hot air, 95%-98% water will be evaporated only in 5-35 seconds. It is specially suitable for heat sensitive material.
Because product is dried in hot air, so shape of product keeps the same as sprayed drops. It is well dispersed ball shape with good flowability and solubility.
Stable operating:
it is automatic and continuous operating equipment which is easy for controlling and adjusting.
Simplified working process:
it is suitable for drying slurry with water content between 40%-90%. It will produce uniformed powder and save process such as grinding and sieving. Operating condition is good and avoid ash leaking during drying process. Raw material can be solution, slurry, emulsion, suspension, paste, melting material, or even caky material.

Frequently Asked Questions
How does the centrifugal spray dryer work?
Filtered and heated fresh air enters the air distributor at the top of the dryer, spiraling evenly into the drying room. Raw liquid materials are passed through a high-speed centrifugal sprayer, turning into fine mist droplets. Upon contact with the hot air, moisture evaporates instantly to produce the final powder.
What is the typical drying speed of this equipment?
The drying speed is exceptionally fast. Once the liquid is atomized into small drops, the contact surface area increases significantly. 95% to 98% of the water evaporates within 5 to 35 seconds, making it ideal for heat-sensitive materials.
What types of materials can be processed with this dryer?
It is highly versatile and handles solutions, slurries, emulsions, suspensions, pastes, and melting materials. It is widely used in industries such as chemical manufacturing, pharmacy, plastics, resins, food production, and ceramics.
What are the typical operating temperatures?
The inlet temperature ranges between 140°C and 350°C (automatically controlled to match material needs), while the outlet temperature typically ranges from 80°C to 90°C.
What is the standard powder recovery rate?
The equipment is highly efficient, featuring a dried powder restoring (recovery) rate of ≥95%, ensuring minimal material loss during the cyclone separation process.
