Abstract: The present invention relates to a snow ice maker, comprising a coupling shaft (40) assembly wherein refrigerant injection capillary tubes (20) and a refrigerant gas outlet tube (30) are arranged in a main passage (41), and the passage (41) is closed at a welding part (43) as a result of the capillary tubes (20) and a refrigerant gas inlet tube being simultaneously provided. The refrigerant injection capillary tubes (20) comprise ends (22) arranged in proximity to an injecting position inside a cooling drum, and the refrigerant injection capillary tubes (20) are arranged by collecting the refrigerant injection capillary tubes (20) in the passage (41) of the coupling shaft (40); extending the refrigerant injection capillary tubes (20) to the outside of the cooling drum; combining the refrigerant injection capillary tubes (20) at a multiple connection part (21); and directly connecting the refrigerant injection capillary tubes (20) to a refrigerant supply tube (52) of a refrigerant compressor.
