摘要： [Object]To provide a calculation method and calculation device for an average sublimation interface temperature, bottom part temperature, and sublimation rate of the whole to-be-dried material introduced into a drying chamber of a freeze-drying device without contaminating or collapsing the to-be-dried material.[Solution]The present invention is applied to a freeze-drying device that includes a drying chamber DC, a cold trap CT, vacuum adjustment means for adjusting the degree of the vacuum in the drying chamber DC, and a control device CR for automatically controlling the operations of the above elements. The control device CR stores a required relational expression and a calculation program, drives the vacuum adjusting means during a primary drying period of the to-be-dried material to temporarily change the drying chamber's degree of vacuum Pdc in an increasing direction, and calculates the average sublimation interface temperature Ts, bottom part temperature Tb, and sublimation rate Qm of the to-be-dried material during the primary drying period in accordance with the relational expression and with measured data including the drying chamber's degree of vacuum Pdc and the cold trap's degree of vacuum Pdt, which are obtained before and after the temporary change.
