Abstract: A mechanism is disclosed for microwave vacuum drying of pharmaceutical powders and the like. The mechanism includes a drying chamber, a source of microwave radiation, a means for mixing product within the chamber, and a means for introducing a vacuum into the chamber during the drying process. The chamber is vertically oriented, with the microwave radiation introduced at the top of the chamber and mixing occurring at the chamber's bottom. The chamber has a removable lid at its top, and a support structure adapted for loading and unloading dried product from the chamber. The mixing mechanism is a motor driven shaft with one or more mixing blades. The shaft and blades may be microwave transparent. In the preferred embodiment, the chamber is sufficiently deep such that a layer of product to be dried can cover the shaft and blades and microwave radiation can be prevented from penetrating through the product to the shaft and blades.
