LPG High-Speed Centrifugal Spray Dryer

DESCRIPTION

The spray drying technology is the widest used in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquoid and pumpable paste states. Therefore, the spray drying is one of the most desired technologies when the particle size and distribution of the final products, their residual water contents, and the stocking density and the particle shape can meet the precision standards.

WORKING PRINCIPLE

The air enters into the air distributor which on the top of the drier after filtering and heating. The hot air in spiral form equably enters into the drying room. When liquid raw material is passing through the high-speed centrifugal sprayer on the top of the tower, it will be rotated and sprayed into the extremely fine mist liquid beads. Raw material can be dried to the final products instantly while it contact with the heated air. The finished products are discharged continuously from bottom of the drying tower and cyclones segregator. The waste gas is discharged from blower.

FEATURES

1.The drying speed is rapid. When liquid raw material is atomized, the surface of the material will be enlarged greatly. 95% - 98% of water can be evaporated instantly in the hot airflow and the drying is only a few seconds. This dryer is especially suitable to dry the heat sensitive material.
2.The uniformity, flow capability & solubility of the dryer are very good. The finished products have high quality and high-purity.
3.Simple and stable operation, convenient control and debugging, easy to achieve automatic operation.
4.The production process is simple, The dryer can dry the liquid material which contains 40%-60%(90% for special materials) of moisture into powder at once. There’s no need for smashing or sieving after drying so the operational environment is clean and in healthful condition, it also can avoid powder flying in the air during drying process.

Notes: The evaporated amount of water is related to the characteristics of raw materials and the temperature of inlet air and outlet air. When the temperature of outlet air is 90°C, the water evapo rated curve is listed in above table (for reference only). If the product have been improved or updated by new technology, the related parameters will be change accordingly!

Attention to order
