DESCRIPTION
After fresh air is filtered and heated, it enters into the air distributor which on the top of the drier. 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 heatedair. Finished products are discharged continuously from bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.
FEATURES
1.Drying speed is rapid. When liquid raw material is atomized, the surface of the material will be enlarged greatly. In the hot airflow, 95% - 98% of water can be evaporated instantly. Time of completing the drying is several seconds. This is especially adapt to dry heating sensitive material. |
2.Finished products have high quality, high-purity, good uniformity, good flow capability & solubility advantages. |
3.Simple and stable operation , convenient control and debugging, easy to achieve automatic operation |
4. Process of production is simple, it is an ideal choice for liquid material which contains 40%-90% of water and want to dry it to powder once, this type of machine can reduce the procedure of smash and sieve, the operational environment is superior , always clean, and under healthful condition, it also can avoid powder flying while drying.
