Spray drying is a common technique used to convert a liquid, a slurry, an emulsion, a suspension or a low viscosity paste into dried powder. This process involves atomizing (or spraying) the feed material into very small droplets which subsequently come into contact with a hightemperature air-drying medium in a drying chamber. The large surface area of the atomized droplets of the feed material imparts a very fast drying rate (Woo, 2017). Due to the unique characteristics of the spray-drying process, especially its short drying time and rapid water evaporation, it has been used not only in the food and dairy industries, but also in many other industrial sectors such as pharmaceuticals, agrochemicals, chemicals, detergents, pigments, biotechnology and ceramics (
