Document Type and Number:
WIPO Patent Application WO/2024/048797
Kind Code:
A1
Abstract:
[Problem] To provide a drying device capable of uniformly drying a plurality of frozen drying target objects, under reduced pressure, by means of microwave radiation. [Solution] A drying device 1 for drying a plurality of frozen drying target objects 5 by means of microwave radiation comprises: a microwave generator 11 for generating microwaves; a chamber 13 into the interior of which the microwaves generated by the microwave generator 11 are guided; and a control unit 14 for controlling the microwave generator 11 to cause a frequency of the microwaves to vary repeatedly such that, when averaged over time, the plurality of drying target objects 5 present in the chamber under reduced pressure are irradiated uniformly by the microwaves.
