Abstract (en)
[origin: WO9510744A1] A freeze-drying plant consisting overall of a condenser chamber (2) and a drying chamber (1), the drying chamber (1) of which is fitted with a system of superimposed, possibly adjustable supporting plates (9) acting as supports for phials (13) containing a drying substance, is fitted for the continuous determination of the mass of the drying substance and hence to monitor the drying cycle with weighing cells (15) connected to a phial (13) via a clamp arm (16). The weighing cells (15) are either permanently fitted inside the drying chamber (1), e.g. on its wall or on components which cannot move in relation to the wall, or they are directly on the supporting plates (9). The basis of the weighing principle of said weighing cells (15) is that either the supporting plate (9) of the phial (13) concerned is lowered with the weighing cell (15) in a constant position or the weighing cell (15) comprises a lifting device by means of which the phial (13) can be briefly raised. It is thus possible, together with fast measurement processes, to determine the mass of the drying substance virtually continuously without disturbing the drying process.
