Abstract
The present invention provides exemplary systems and methods for producing dry powder formulations. In one embodiment, a system () includes at least one conditioning zone () having an inlet () to introduce an atomized formulation () into the conditioning zone. A controller () controls temperature and relative humidity of the airflow into the conditioning zone to allow amorphous-to-crystalline transformation of the atomized formulation. In another embodiment, the formulation is suspended in the conditioning zone for a residence time of sufficient duration to allow surface orientation of surface active components. A dryer () is coupled to the conditioning zone to dry the atomized formulation, and a collector () collects the formulation in powder form.
