Spray Drying in Cyclone Separators

1.1 Spray Drying Spray drying is a method of drying a solution or a slurry, in order to produce a powder. This is done by dispersing the liquid into a gas phase. Major bene ts of spray drying is that the particle size can be controlled by the atomization of the liquid, and spray drying is a fast process compared to other drying methods.
