PROBLEM TO BE SOLVED: To provide an automatic ice making machine in which corrosion products such as rust are not mixed in ice-making water and ice, by improving anti-corrosion properties of an ice making part, and which has enhanced reliability of food sanitation.SOLUTION: An automatic ice making machine circulates and supplies ice-making water to an ice making part 10 cooled by a cooling pipe, and generates ice of required shapes. In the automatic ice making machine, on the outermost layer of the ice making part 10, an electroless nickel-phosphor plated coating 22 containing 10%-15% of phosphorus components is formed with thickness of 15 μm or greater.SELECTED DRAWING: Figure 1 |
