A [lacuna] principally for loading and unloading the utility surface (3') of the drying chamber (2) of a freeze drying system, which utility surface is located at a defined height position, the unloading position, is characterized by a carriage (8), which is disposed slightly above said utility surface and extends, during loading or unloading, transversely with respect to a movement direction (8') and in parallel with the utility surface and which forms a movable guiding edge for the drying vessels (5), and by guides (7), which are disposed on both sides of the utility surface (3), extend in parallel with the said movement direction and form fixed guiding edges for the drying vessels (5). The carriage (8) is driven by two linear motors, the respective secondary parts (18) of which are fixedly connected to the ends of the carriage (8) on both sides and are supported on the guides (7) which at the same time accommodate the primary parts. All of the components of the device thus defined are located inside the drying chamber (1), wherein a mechanically extraordinarily simple and low-wear design is achieved. The structural design of this type of device renders it possible inside the drying chamber (2) to provide lateral guides (7), which are independent of the utility surface, and is suitable for the upgrading existing freeze drying systems in stages with a view to using a plurality of carriages, a lateral displaceability of the guides (7), i.e. which is to be arranged transversely with respect to the movement direction (8'), etc. By virtue of the fact that the essential components of this device can be formed in a hermetically encapsulated construction, and are thus accessible for sterilization, reliable handling capability is also provided in terms of hygiene.
