An ice maker is a device designed to produce ice automatically. It can be found in various forms, including standalone units, built-in appliances in refrigerators, and portable models. Ice makers work by freezing water in a specific shape, typically in cubes or nuggets, which can be used for drinks, food preservation, and other purposes. Most ice makers operate by filling a mold with water, freezing it, and then releasing the ice when it's ready. Some models can produce ice quickly, making them convenient for parties or gatherings. They are commonly used in homes, restaurants, and bars to ensure a steady supply of ice for beverages and food service.
