The present invention relates to a rotary joint-type drum-shaped device for manufacturing snow-ice. More specifically, the present invention provides a drum-shaped device ice-maker consisting of: a refrigerant supply and recovery part inserted and installed inside an ice-making drum to inject and discharge refrigerant; and a rotary joint-type rotating part outside the cooling drum to be able to reduce a space inside the drum and thus enhance cooling efficiency. Accordingly, the purpose of the present invention is to install a refrigerant spray pipe inside the cooling drum near to the inner surface of the drum, spray the refrigerant at uniform pressure during the spray of the refrigerant, and maximize cooling efficiency to be able to manufacture ice evenly on the whole surface of the ice-making drum. To solve the inconvenience of a traditional cooling device that overall replacement or repair has to be conducted instead of individual repair if a defect is generated in a fixing part installed inside the drum, rotary joint-type drum-shaped device for manufacturing snow-ice according to the present invention enables individual repair in the case of defects being generated in many components by installing the rotary joint-type rotating part, which consists of main components outside the cooling drum, and has workability improved in terms of costs and time by reducing need for repair on the whole. |
