The quality and type of ice produced by the ice maker are crucial, as different types of ice serve different purposes. Common types include full cubes, hollow cubes, square cubes, crushed ice, granular ice, and flake ice. Consider the needs of your catering business, such as beverage service, food cooling, or product displays, and choose an ice maker that can produce the appropriate type of ice to meet these requirements. Additionally, ensure that the produced ice is of high quality, transparent, and free from impurities.
