  • Spray Drying Process - an overview | ScienceDirect Topics

    Spray-drying is a process by which a fluid feed material is transformed into a dry powder by spraying the feed into a hot medium. Spray-drying is a complex process, but we now propose a simple mechanism to describe the spray-drying process of ceramics with four steps as illustrated in Fig. 4.1 : 24 (i) droplet formation; (ii) evaporation and ballooning; (iii) explosion; (iv) particle formation.
