Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device and a method for freezing and defrosting water containing objects capable of accurately detecting a change of phase during freezing or defrosting of water contents contained in water and ice, food, a DNA sample, or the like, thereby raising ice making speed, maintaining a supercooled state, allowing confirmation of complete freezing of a whole object from the outside, and capable of holding the whole object just prior to defrosting and shortening defrosting time. SOLUTION: A cooling/heat dissipation device 12 is provided for carrying out cooling or heat dissipation of the water content containing object 1 containing water contents, a millimeter wave irradiating device 14 is provided for irradiating a millimeter wave 2 with a wavelength of 0.1-100 mm on the water content containing object, a millimeter wave detector 16 is provided for detecting a millimeter wave 3 having transmitted through the water content containing object, a phase change detector 18 is provided for calculating an absorbed amount of the water content containing object from an irradiation output and a detected output of the millimeter wave and detecting the change of phase of the water content containing object, and a freezing/defrosting controller 20 is provided for controlling the cooling/heat dissipation device on the basis of the detected change of phase.
