PROBLEM TO BE SOLVED: To shorten time for thawing.SOLUTION: An apparatus for pressure-reduced thawing includes: an openable/closable pressure-reduced container 3 for housing frozen food a pressure-reducing part 5 for reducing the pressure in the pressure-reduced container 3 and a heating part 7 for keeping a hot liquid in the pressure-reduced container 3 at a predetermined temperature, and thaws a frozen food material by reducing the pressure in the sealed container 3 while immersing the frozen food material in the sealed container 3 to the hot liquid, and boiling the hot liquid. The hot liquid is in a boiled state by the reduced pressure and the hot liquid in a boiled state is in a stirring state by colliding with the surface of the frozen food material and thus greatly promoting heat exchange on the surface of the frozen food material and allowing to thaw quickly.COPYRIGHT: (C)2012,JPO&INPIT【課題】解凍時間を短くすることを可能とする。【解決手段】冷凍食を収容する開閉可能な減圧容器3と、この減圧容器3内を減圧する減圧部5と、減圧容器3内の温液を設定温度に保持する加温部7とを備え、密閉容器3内に冷凍食材を温液に浸しながら密閉容器3内を減圧して温液を沸騰させ冷凍食材を解凍する。 減圧によって温液が沸騰状態となり、この沸騰状態の温液が冷凍食材の表面に激しく衝突して攪拌状態となり、冷凍食材の表面での熱交換を大きく促進させ、素早い解凍を行わせることができる。【選択図】図1
