GLOSSARY: Spray Drying

Spray Drying refers to the process by which a material in suspension is converted into droplets that may be coated by a substance, either melted or dissolved in the droplet's media. The action in spray drying is primarily that of evaporation, energy is applied to the droplet forcing evaporation of the media with both energy and mass transfer through the droplet. Examples of this technology include pharmaceutical tablet granulation, and rapid drying which results in free-flowing powders on a continuous basis.
