Spray Dryer

Identification of Facility
TitleSpray Dryer
AcronymSpray Dryer
Key wordsSpray drying, powder, mild drying, solubility, shelf life, thermally-sensitive material
Latest version2013/04/29
ManufacturerGEA Niro
DescriptionA spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is collected in a drum or cyclone. The liquid input stream is sprayed through a rotary disk or nozzle into a hot air stream (120-250 °C) and vaporises. Solids form as moisture quickly leaves the droplets. The temperature residence time on the product is around 0.5-1 seconds at 60-100 °C. Droplet sizes can range from 10-40 µm with nozzle and 20-50 µm with rotary disk. Spray dryers can dry a product very quickly compared to other methods of drying. They also turn a solution or slurry into a dried powder in a single step, which can be advantageous for profit maximization and process simplification. Spray drying is the second mildest drying method after freeze-drying; it allows improving the solubility and shelf life of the product.
