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.
Work Principle Description
After filtering and heating, the air enters into the hot air distributor at the top of the centrifugal spray dryer, and the hot air will spirally and evenly goes into the drying chamber. The material liquid via high-speed centrifugal atomizer rotates into extremely thin vaporific liquid globule and parallelly flows with the hot air, and then the liquid will be dried into powdery products in a very short time (5-10 seconds). The waste gas after filtering will be expelled through the fan. For the wet organic solvent materials, the spray drying machine can be designed with closed cycle process. It can utilize cyclic nitrogen to dry the materials.
