Meat-aging apparatus, meat-aging method thereof, and meat-aging system and refrigerator

A meat-aging apparatus, comprising:

• a communicator;
• a display;
• a photographing unit configured to photograph an image of meat stored in the meat-aging apparatus;
• an illumination unit configured to irradiate light to the meat;
• a temperature controller configured to measure a temperature of the meat-aging apparatus;
• a humidity controller configured to measure a humidity of the meat-aging apparatus;
• a ventilation unit configured to emit an air inside the meat-aging apparatus to an outside or the outside air to an inside;
• a storage configured to store at least one of an image indicating a type of meat related to a species of animals and an image indicating a state of meat;
• and
• a processor configured to:
• determine a color distribution from the photographed image of the meat,
• compare the determined color distribution with a plurality of stored images of meat,
• based on a coincidence between the photographed image of the meat and at least one of the plurality of stored images of meat being equal to or greater than a predetermined value, determine the type and the state of meat with reference to the type and the state of meat corresponding to the stored images,
• control the communicator to receive at least one of recipe information comprising a preference rating and a count of downloads, and corresponding to the determined type and the determined state of the meat from an external server,
• control the display to display the at least one of recipe information with the preference rating sorted by the count of downloads,
• based on one selected recipe information among the at least one of recipe information, control the illumination unit to irradiate light to the meat and control the ventilation unit to ventilate the inside air based on the measured temperature and the measured humidity of the meat-aging apparatus to age the meat at a predetermined target aging degree according to the selected recipe information,
• wherein the selected recipe information includes information irradiation time of light to be irradiated to the meat by aging degree for aging the meat,
• wherein the aging degree is divided into a plurality of levels depending on a degree of aging, and
• wherein a first level of the plurality of levels indicates a state where the meat is first stored in the meat-aging apparatus and a final level of the plurality of levels indicates a state where the meat reaches the predetermined target aging degree.
