PROBLEM TO BE SOLVED: To eliminate substantial problems in view of food sanitation management occurred in peeling-off of rusts and dropping from ice-making chambers and their mixing in ice-making water or ice blocks due to contact of applied atmosphere of an ice-making machinery with substance that promotes corrosion at the ice-making chambers under an arrangement that the inner and outer surfaces of the ice-making chambers at a closed cell-type injection type ice-making machinery are applied with molten tin plating surface treatment for preventing occurrence of rusts in view of food sanitation.SOLUTION: Anti-corrosion characteristic of ice-making chambers 12 is remarkably improved by applying electroless nickel-phosphorus coating to surfaces of the ice-making chambers 12.SELECTED DRAWING: Figure 2 |
