All About Spray Drying - Process and Applications in Industry

Apr 10, 2022 Spray Drying Processes. Spray dryers take a liquid stream and separate the solute as a solid and the solvent into a vapor. A drum or cyclone usually collects the solid. The liquid input stream sprays into a hot vapor stream and vaporizes. As moisture rapidly leaves the droplets, a solid forms.
