Introduction to spray drying

- Dec 12, 2019-

Spray drying is a method for systematic drying of materials. 


Through mechanical action, the materials to be dried are dispersed into very fine particles like mist, (to increase the evaporation area of moisture, speed up the drying process) in contact with hot air, and remove most of the moisture in an instant, so that the solids in the material The material is dried to a powder. 


This method can directly dry the solution and emulsion into powder or granular products, and can eliminate the steps of evaporation and pulverization. It is suitable for heat-sensitive drugs and can be used for preparing microcapsules.
