Abstract: A mechanism for batch drying of a powdered or particular product with a microwave vacuum system is disclosed along with a method of controlling the drying process. The mechanism includes a chamber for drying the product. The product is contained in an internal product container. The product container and chamber are coordinated to allow easy opening on a rail system. The mechanism includes a means for inducing a vacuum in the chamber that can also with draw solvent vapor from the chamber. A source of microwaves for the chamber is provided, and the product container has an agitation mechanism for the product. A means for controlling the drying operation is also disclosed. The preferred embodiment of the mechanism include a solvent recovery system. The method of controlling the drying process allows for the selective halting of the drying operation upon achieving selectable parameters. The control systems also allows selectable parameters to be maintained during the drying operation.

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.
