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.
Black Liquor Spray Dryer characteristics
Its dry speed is very quick. In general, it needs 5-15 seconds. It has feature of momentary dry.
Because raw material can be dried momentarily. Especially, it is suitable for drying thermal sensitive raw materials. It can maintain color, smell and smell of raw materials.
Its operation is stable and simple. Its regulation and control is very convenient. It is easy to realize continuous operation.
The distribution, fluidity and solubility of product are good.
