Abstract

Spray drying unit operations are used for the production of dried powder across a wide range of material processing applications from food to fertilizer to pharmaceuticals (1). This one-step, continuous process converts a bulk liquid into powder and has been shown to be both robust and scaleable, with the appropriate hardware and process modifications. Materials previously thought not suitable for spray drying such as proteins, have been successfully processed with appropriate formulation and process design. In addition, the ability to rapidly form individual particles enables a level of particle engineering well suited to producing pharmaceutical powders, in particular for inhalation drug delivery.
