General Description:

Spray Drying is a unique method to convert a solution, suspension or emulsion into a solid powder in one single process step. It is a widely established process in many industries such as pharmaceuticals, food, chemical or material science.

Spray Drying consists of three basic steps, drying begins with atomization of a liquid feed into a spray of fine droplets. The spray is then contacted with, and suspended by, a heated gas stream, allowing the liquid to evaporate and leave the dried solids in essentially the same size and shape as the atomized droplet. Finally, the dried powder is separated from the gas stream and collected. The spent drying gas is treated to meet environmental requirements and then exhausted to the atmosphere or, in some cases, recirculated to the system.
