  • Calculation method and calculation device for sublimation interface temperature, bottom part temperature, and sublimation rate of material to be dried in freeze-drying device
    Patent number: 9488410
    Abstract: [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.
