    摘要: Freeze drying apparatus and associated lyophilization procedures are provided employing vapor flow detection and/or vacuum control for monitoring and control of the lyophilization process. The vapor flow detector, such as a windmill sensor, is disposed to monitor vapor flow from product undergoing lyophilization. In a batch process, vapor flow is collectively monitored with the vapor flow detector between the process chamber and condenser chamber, while in a manifold configuration separate vapor flow detectors are employed at each flask attachment port. A windmill sensor provides visual feedback to an operator and/or electronic feedback to a system controller. A vacuum control system is also provided for use with or independent of vapor flow detection. This vacuum control disconnects the vacuum source from the process chamber when pressure within the process chamber falls below a first predefined set point. The vacuum source is then reconnected if process chamber pressure rises above a second predefined set point.

    摘要: A method and an apparatus for effecting freeze-drying specimens containing solvents or condensing solvents having a shallow pan treatment chamber with little or no obstructions, holes or orifices. The treatment is effected by cooling the base of the chamber by using coolant-containing coils mounted beneath the base of the chamber. The direct thermal conduction of heat through the base of the chamber provides a more effective method of both cooling specimens and condensing solvents, typically water. A source of vacuum is provided to the chamber by a conduit located in the cover, sidewalls or base of the chamber. The method and apparatus may employ a moveable specimen holder positioned in the chamber. The moveable specimen holder may be mounted on a perforated tube which slidably engages a conduit in the base of the chamber. The perforated tube may a conduit to the source of vacuum. The specimen holder may be supported by the perforated tube and by a rigid metal wire which is used to elevate the specimen holder above the base of the chamber. By varying the elevation of the specimen holder various treatments can be effected. The method and apparatus are applicable to manifold type freeze-drying and can be used simply as a cold trap.

    摘要: The present invention provides methods and apparatus for freeze drying in which a solution, which can be a radioactive salt dissolved within an acid, is frozen into a solid on vertical plates provided within a freeze drying chamber. The solid is sublimated into vapor and condensed in a cold condenser positioned above the freeze drying chamber and connected thereto by a conduit. The vertical positioning of the cold condenser relative to the freeze dryer helps to help prevent substances such as radioactive materials separated from the solution from contaminating the cold condenser. Additionally, the system can be charged with an inert gas to produce a down rush of gas into the freeze drying chamber to also help prevent such substances from contaminating the cold condenser.
