Abstract
PURPOSE:To save the time and trouble of transferring a thawed frozen food to another refrigerator, and to prevent the deterioration in quality during the storage of the thawed food, by storing the food with a vacuum thawing device comprising a cooler and a means communicating to the air under atmospheric pressure. CONSTITUTION:The frozen food 16 is placed in the vacuum chamber 12. The drain valve 38 is closed to open the water supply valve 34, and water is fed to the water tank 30. The vacuum breaker 28 is then closed to open the reducing valve 24, and the vacuum pump 22 is driven to evacuate the vacuum chamber 12. Low- temperature steam is brought into contact with the food 16 in vacuo while heating the water in the tank 30 with the heater 40 if necessary. The steam is condensed on the surface of the food 16 to thaw the food 16 by the latent heat. After thawing, the breaker 28 is opened to communicate the chamber 12 to the air, and the valve 38 is simultaneously opened to drain the water from the tank 30. The valves 24, 28, 34 and 38 are then closed to circulate the refrigerant from the refrigerator 46 through the cooler 42 to cool the chamber 12, and the thawed food is stored.
