Schematic presentation of the spray-drying procedure: The solution is pressured and then atomized to form a “mist” into the drying chamber. The hot gas (air or nitrogen) is blown into the drying chamber too. This hot gas allows the evaporation of the solvent. The capsules are then transported to a cyclone separator for recovery.
