PROBLEM TO BE SOLVED: To provide a thawing machine intended for solving concerns of conventional long-time thawing and quality deterioration in thawing, performing effective short-time thawing and suppressing quality deterioration, for thawing a large-scaled frozen food material or a frozen material packaged in a layered block. SOLUTION: This thawing machine of a thawing treatment water circulating jet stream includes circulation-jetting a thawing treatment water 2 and using the occurrence of cavitation, with a circulation pump impeller of high-speed rotation so as to realize short-time thawing in cold temperature water, in cooperation with jet steam. Furthermore, the thawing machine is installed with an ultraviolet germicidal lamp 20 in the water of circulation path. COPYRIGHT: (C)2009,JPO&INPIT
