The present invention relates to a device for thawing food at a low temperature by providing conditions necessary for thawing food by connecting a food thawing compartment with a circulation duct to form a closed-circulation duct and applying a heat pump to the closed-circulation duct. The purpose of the present invention is to provide a low-temperature thawing device for over-spraying droplets to the inside of the closed-circulation duct: by forming an air circulation duct to successively include an over-spraying device spraying the droplets of which a preset diameter is a micrometer or smaller, a heat exchanger of the heat pump controlling the temperature and humidity of air, and an electric heating device controlling a precise air temperature condition therein and by forming one closed-circulation duct through forming the thawing compartment where frozen food to be thawed is stored at a predetermined part of the air circulation duct and by applying the heat pump for controlling to allow air flowing into the thawing compartment to be in a state where saturated moist air and mist are mixed. The purpose of the present invention is to provide the thawing device for thawing frozen food capable of preventing problems such as the deterioration on the surface of frozen meat or the frozen food in which processing is necessary or a discharge of juices, by evenly transmitting heat to the inside to the frozen food using latent heat of vaporization of the supersaturated moist air from the surface of the frozen food, through allowing the supersaturated moist air, to which the fog-type droplets with a diameter at a micrometer or smaller and saturated moist air are mixed, to forcibly flow inside the closed-circulation duct.COPYRIGHT KIPO 2016본 발명은 식품 해동실을 순환덕트와 연결하여 폐순환덕트를 형성하고, 폐순환덕트에 히트펌프를 적용하여, 식품해동에 필요한 조건을 제공하여, 저온으로 식품을 해동시키는 장치에 관한 것이다.설정직경이 마이크로미터 이하의 액적을 분무하는 과분무장치, 공기의 온습도를 조절하는 히트펌프의 열교환기, 및 정밀한 공기온도조건을 조절하는 전기가열장치가 순차적으로 내부에 포함되도록 공기 순환덕트를 형성하고 상기 순환덕트의 일정지점에 해동할 냉동
