FREEZE DRYING INSTALLATION

The invention relates to a freeze drying installation (8), including a device (9) for moving containers (10) such as vials or the like along a surface supporting the containers to load and/or unload the containers into a freeze dryer processing chamber (200), wherein the device comprises two articulated arms, wherein each articulated arm comprises a first rigid upper arm and a first rigid lower arm connected to each other by a first rotary joint, wherein the ends of the two articulated arms are connected to a rigid transfer bar by articulated joints, which are spaced apart from each other when seen along an extension axis of the transfer bar, and wherein the two articulated arms are driven by at least one driving unit in a synchronised manner such that the transfer bar is movable along a loading and/or unloading axis to load or unload containers into or from the freeze dryer processing chamber.
