ABSTRACT:
A method and apparatus for loading and unloading freeze-drying apparatus including at least one placement surface adapted to receive containers holding a product to be freeze-dried. The containers are placed on a table top of a transfer table, and the transfer table is brought into proximity with the placement surface in a chamber of a freeze-drying apparatus. A retractable frame assembly, movably secured to the transfer table, is used to transfer the containers from the transfer table top to the placement surfaces. The frame assembly is retracted from the chamber, and the freeze-drying process may then be implemented. Upon completion of freeze-drying, the frame assembly is introduced into the chamber, and is actuated to transfer the containers from the placement surfaces to the transfer table.
