Introduction to Spray Drying

Spray drying is used in the production  of a wide variety of consumer goods, from the food we eat, to the medicines that keep  us safe and healthy. It is used throughout the food manufacturing and pharmaceutical industries  to rapidly dry liquid product feed into a powdered material using heated gas for a variety  of consumer and industrial applications. The process begins when a liquid product feed is  passed through a special nozzle called an atomizer.

The atomizer disperses the liquid stream  as a mist of fine droplets into a heated gas atmosphere to facilitate the drying  process. There are various nozzle designs such as pressure nozzles and rotary nozzles. The  type of atomizer used will vary by application.
