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.
