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.
