Spray drying is a process of drying water solution, emulsion, and so on. It is widely used in Industrial Chemistry and the food industry. Spray drying is usually a method of injecting a fluid mixture into the hot dry air for drying. The solvent usually is water-based; it is instantly volatilized by hot air. This evaporation process removes heat quickly so that the product is dried gently without being affected by heat. The product becomes powder, particle, or lump within seconds.
