US 9,803,906 B2 · Snow ice maker

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. The refrigerant gas outlet tube (30) is connected to a multiple inlet tube (33) in an ice-making drum, and the refrigerant gas outlet tube (30) is arranged by directly connecting the refrigerant gas outlet tube (30) through the main passage in the coupling shaft (40), from a connection part (31) outside the cooling drum to a gas inlet tube (54) of a condenser. According to the present invention, clean snow ice can be used because supplied water for ice making is frozen in an ice-making drum, edible powder ice can be obtained by cutting the ice layers of the ice-making drum with a cutter, and water for ice making is sterilized by ultraviolet rays. In addition, the ice-making drum can be cleaned and sterilized by heated water and vapor so that ingredients including milk, sugar and juice can be ice-made and variously used in a summer environment of high temperature and humidity.
