Provided is a dry aging system using oxygen in which a separate dry-aging room is provided in a refrigerating compartment, and a mixed gas using oxygen is supplied into the dry-aging room so as to solve a blacking and browning phenomenon of a meat surface, which is led to an increase in loss rate and an increase in edible meat cost, which are disadvantages of existing dry-aging, thereby allowing the meat surface to be maintained in a bright red color through meat color fixation, minimizing the occurrence of the blacking and browning phenomenon to reduce the loss rate of the edible meat, and supplying flavorful dry-aged meat at a more reasonable price. Also, the blacking and browning phenomenon occurring on the generally dry-aged meat may be significantly reduced to produce aesthetically and tastefully very superior dry-aged meat.

Disclosed is an automatic immersion ice-coating machine, including a frame, an ice-coating working pool, a feed port, a conveying device, a control system and a driving system. A first side of the ice-coating working pool communicates with a buffer tank. A bottom of the ice-coating working pool is stepped or inclined, and a drain valve is provided at a bottom of the ice-coating working pool. The conveying device includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located under the feed port, and a lower portion of the first conveyor belt is lower than the liquid level, and the second conveyor belt communicates with the discharge port. The first and second conveyor belts are made of stainless steel mesh belts, and surfaces of the stainless steel mesh belts are provided with separators in a spaced manner.

Provided are: ice which has excellent cooling capacity; a production method therefor; a method for producing a cooled article; and a refrigerant. Also provided are: ice in a non-separating state; and a production method therefor and ice which satisfies conditions (a) and (b) and is from a liquid that includes an aqueous solution comprising a solute. (a) The temperature of the ice after melting completely is less than 0 C. (b) The rate of change of the solute concentration in the aqueous solution generated from the ice in the melting process is 30% or lower. The refrigerant includes the ice. The refrigerant also includes water which comprises the same solute as the solute included in the ice, wherein the ratio of the concentration of the solute in the ice and the concentration of the solute in the water is preferably 75:25 to 20:80.
