What is spray drying?

Spray drying is a method of producing powdered products by spraying a liquid or slurry at very high pressures into a heated air stream,  usually 160°C – 205°C (if the liquid is flammable or oxygen-sensitive then nitrogen is used).

Special nozzles used for the process atomise the liquid into extremely fine droplets which when sprayed into the heated chamber causes the liquid to flash off and evaporate leaving a small solid particle. These are collected from the chamber into a drum or cyclone which is kept ‘fluid’ through continual shaking, resulting in very fine free-flowing powder as the product.

Spray drying is used to produce a number of products in various industries including Dairy, Pharmaceutical and Food and Beverage.

Products manufactured through spray dry include

 

Powdered milk
