ABSTRACT:
An intermediate support plate (4) is located between the freeze-drying chamber and the condensation chamber and is equipped with a closeable port; in order to be able to properly adjust the orifice of the port it is formed by two discs (15, 18) that can be rotated relative to each other around a central axis of rotation. Each disc carries circular holes (21, 22) at a radial distance away from the axis of rotation and these holes are so located and designed that by rotating the discs a position of complete axial overlap, one of zero axial overlap and any position in between can be achieved.
