China LPG Series High-Speed Centrifuge Spray Dryer - Leading Suppliers and Factory for Efficient Drying Solutions
Principle
After fresh air is filtered and heated, it enters into the air distributor which is on the top of the dryer. The hot air in spiral form equably enters into the drying room. When liquid raw materials 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 contacts with the heated air. Finished products are discharged continuously from the bottom of the drying tower and cyclone segregator. Wasted air is discharged from the blower.
Applications
After spraying into small drops, the contacting area is greatly increased. 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 the product is dried in hot air, the shape of the product keeps the same as sprayed drops. It is well dispersed ball shape with good flowability and solubility.
It is automatic and continuous operating equipment which is easy for controlling and adjusting.
It is suitable for drying slurry with water content between 40%-90%. It will produce uniformed powder and save processes such as grinding and sieving. Operating condition is good and avoids ash leaking during the drying process. Raw material can be solution, slurry, emulsion, suspension, paste, melting material, or even caky material.

Frequently Asked Questions
Fresh air is filtered and heated, then enters the air distributor at the top of the dryer. The hot air flows spirally and evenly into the drying chamber. Concurrently, liquid raw material is sprayed into an extremely fine mist using a high-speed centrifugal atomizer, drying instantly upon contact with the hot air.
The drying speed is exceptionally fast. Because the liquid is atomized into small drops, the contact surface area increases drastically. 95% to 98% of the water content evaporates within just 5 to 35 seconds, making it ideal for processing heat-sensitive materials.
This equipment can handle a wide variety of raw material states, including solutions, slurries, emulsions, suspensions, pastes, melting materials, or even caky materials with water contents between 40% and 90%.
It is widely used in battery materials, pharmaceuticals (e.g., hydroxy starch, spirulina), chemical production (e.g., dyestuffs, pesticides, catalysts), plastics/resins, food industries (milk powder, proteins), and ceramics.
The inlet temperature ranges from 140°C to 350°C and is automatically controlled to match process requirements. The outlet temperature is typically maintained between 80°C and 90°C.
The LPG Centrifugal Spray Dryer achieves a high dried powder restoring (recovery) rate of ≥95%, with finished products continuously discharged from the bottom of the drying tower and the cyclone segregator.
