PURPOSE: To advance a fermentation or ripening by varying chemical composition of conserved food or water molecule gathering state by providing infrared ray radiating means at least in one chamber of a refrigerator.
CONSTITUTION: A far infrared ray lamp 10 is provided at the center of a ceiling of a ripening box 3. The surface of a glass bulb of a lamp 10 is coated with far infrared ray radiating paint, and further overcoated with a protective film made of silicone resin for enhancing the coating strength. When a voltage is applied to the lamp 10, a filament current flows to generate heat, the heat is transferred to the film on the surface of the bulb, and far infrared ray is radiated over the whole area in the box 3. Temperature in the box 3 is regulat ed to a set temperature of 10 - 55°C by a temperature regulator composed of a temperature regulating variable resistor and a temperature sensor 13 pro vided on a control panel by opening or closing a switching relay. Thus, functions of fermenting, ripening or conserving in suitably eating state of food can be loaded.
