Dry aging system using oxygen

A dry aging system using oxygen, comprising:

• a refrigerating compartment;
• one or more dry-aging rooms installed in the refrigerating compartment;
• a vacuum pump configured to vacuumize insides of the one or more dry-aging rooms;
• an oxygen tank configured to store oxygen;
• a carbon dioxide tank configured to store carbon dioxide;
• a nitrogen tank configured to store nitrogen;
• a gas mixer configured to mix the oxygen supplied from the oxygen tank, the carbon dioxide supplied from the carbon dioxide tank, and the nitrogen supplied from the nitrogen tank with each other;
• a cooling pipe installed in the refrigerating compartment and configured to cool a mixed gas supplied from the gas mixer and supply the cooled mixed gas into the one or more dry-aging rooms;
• a humidity controller configured to supply moisture into the one or more dry-aging rooms;
• and
• a controller configured to separately control the one or more dry-aging rooms, configured to set a ratio of the oxygen, the carbon dioxide, and the nitrogen, which are supplied into each of the one or more dry-aging rooms, to supply the mixed gas of the oxygen, carbon dioxide and nitrogen, and periodically detects the ratio of the oxygen, the carbon dioxide, and the nitrogen within the one or more dry-aging rooms so that, when the detected ratio is different from the set value, the vacuum pump is driven to vacuumize the insides of the one or more dry-aging rooms and to supply the mixed gas of the oxygen, carbon dioxide and nitrogen corresponding to the set value again into the one or more dry-aging room by using the gas mixer,
• wherein, when a ratio of the carbon dioxide is fixed, and a ratio of the oxygen increases, the controller supplies the mixed gas while decreasing a ratio of the nitrogen and controls the humidity controller to increase in humidity, and
• when the ratio of the carbon dioxide is fixed, and the ratio of the oxygen decreases, the controller supplies the mixed gas while increasing the ratio of the nitrogen and controls the humidity controller to decrease in humidity.

• wherein a ratio of the carbon dioxide is fixed to 20%, the oxygen is contained at a ratio of 20% to 80%, and the nitrogen is contained at a ratio of 0% to 60%,
• wherein, when the ratio of the oxygen increases, the controller supplies the mixed gas while decreasing the ratio of the nitrogen, and when the ratio of the oxygen decreases, the controller supplies the mixed gas while increasing the ratio of the nitrogen.
