McDonald's commercial soft-drink dispensers and ice-making systems produce exceptionally clear and uniform ice due to specialized, high-capacity industrial ice-maker technology. Unlike domestic home freezers where water freezes from the outside inward trapping air bubbles and mineral impurities, commercial machines circulate water continuously over freezing evaporator plates. This directional freezing process forces impurities and dissolved gases out of the forming ice sheets, resulting in dense, crystal-clear ice cubes that melt slower and keep fountain beverages colder.
