Abstract:
A lyophilizer system, adapted for operation in two modes, comprising:a lyophilizing chamber, including shielding from microwaves;a vacuum pumping system for creating vacuum in the lyophilizing chamber;a microwave generator, directing microwaves into the lyophilizing chamber;a refrigeration system for lowering the temperature of the lyophilizing chamber;chamber operating controls for creating a chamber environment in a first mode having a temperature and a pressure that is sufficient to facilitate sublimation in the chamber, and for creating a chamber environment in a second mode having sufficient vacuum and temperature such that when combined with microwaves directed into the chamber, facilitates sublimation in the chamber;a water vapor removal system located in or connected to the lyophilizing chamber for collecting water vapor from the lyophilizing chamber.
