Title:
INTERNAL STATE DETERMINATION METHOD AND INTERNAL STATE DETERMINATION DEVICE FOR FREEZE-DRYING OBJECT, AND FREEZE-DRYING DEVICE
Document Type and Number:
Japanese Patent JP2018169083
Kind Code:
A
Abstract:
To determine a time point at which the inside of an object during freeze-drying is completely dried, in a non-destructive manner.SOLUTION: A internal dry state determination method for a freeze-drying object is a method for determining an internal dry state of an object subjected to freeze-drying, and comprises: a detection step of making a resonance electromagnetic field, which is formed by using a microwave resonator, act on the object, and detecting at least one of the resonance frequency and resonance peak voltage of the resonance electromagnetic field; and a determination step of determining a time point at which the inside of the object is completely dried on the basis of secular change of the detection value obtained in the detection step.SELECTED DRAWING: Figure 3
