Patent attributes
A freeze-drying apparatus (1) includes an arrangement of individual product platforms (19) that are supported vertically in a frame (20) in a drying chamber, in which each platform is able to be moved to a shift level, in which lateral guides (20, 21) designed to support a carriage (15) are arranged with a fixed height position, and which cooperate with the guides (16, 18) of a loading and unloading device. All product platforms (19) in the drying chamber can be loaded by repeating this operation cyclically. In order to unload the drying chamber, the arrangement of the product platforms (19) are moved to such a position above the shift level in which the carriage (15) can be moved as far as its rear limit position inside the drying chamber, travelling underneath each loaded product platform (19).
