ABSTRACT:
A freeze-drying apparatus has a chamber (3) in which are located superposed charging plates (4) as well as loading and unloading equipment. The chamber has a loading aperture (2) equipped with closing doors (11, 12) through which the charging plates (4) are loaded. Equipment for loading the charging plates (4) with containers (5) is positioned in front of the loading aperture (2) and comprises a conveyor belt (6) which serves to supply the containers (5) and a transfer table (7) which is movable between an operating position and an idle position. The transfer table bridges a gap between conveyor belt (6) and the charging plate (4). A loading slider (8) provides push-wise transfer of a plurality of the containers (5) from the conveyor belt (6) via the transfer table (7) onto the charging plate (4). For a reduction of loading times, the transfer table (7) retains substantially in its operating position during the loading of the charging plates (4) and at least the region of the loading aperture (2) above the transfer table (7) is closed following each loading push.
