Abstract: A freeze dryer processes aseptic bulk powder products. The freeze dryer freezes the product by mixing an atomized spray of product with sterile liquid nitrogen to produce a frozen powder. The frozen powder is freeze dried in a vessel by dielectrically heating the frozen powder using electromagnetic radiation such as microwave radiation or infrared radiation, and the frozen powder is continuously agitated using a sterilizable apparatus such as a series of vibrating shelves to maintain even heating and to prevent agglomeration.

Abstract: A compact freeze dryer removes a liquid from a bulk powder product. The freeze dryer utilizes a single cryogenic vessel for both (1) freezing the liquid contained in the bulk product, and (2) condensing vapor resulting from sublimating the frozen liquid. A vacuum pump is connected to the cryogenic vessel for drawing a vacuum in the cryogenic vessel and in a drying vessel. Vapor resulting from subliming the frozen liquid in the drying vessel is drawn into the cryogenic vessel and condensed.
