Title:
WATER-CONTAINING MATERIAL FREEZING/THAWING APPARATUS AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2006/004116
Kind Code:
A1
Abstract:
There is provided an apparatus comprising cooling heat radiation unit (12) for cooling of or heat radiation from water-containing material (1), extremely high frequency wave (EHF) irradiation unit (14) for irradiating the water-containing material with EHF of 0.1 to 100 mm wavelength (2), EHF detector (16) for detecting of EHF (1) having transmitted the water-containing material, phase change detector (18) for computing of the level of absorption by the water-containing material from EHF irradiation output and detection output to thereby detect the state of phase change of the water-containing material, and freezing/thawing control unit (20) for controlling of the cooling heat radiation unit depending on the state of phase change detected.
