Abstract
The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in multiple steps such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.
