An ice maker is a type of refrigeration mechanical equipment that cools water through an evaporator and generates ice through a refrigeration system refrigerant. It uses a refrigeration system and uses water as a carrier to produce ice through a certain device in an energized state. According to the principle of the evaporator and different production methods, the shape of the generated ice blocks also varies; People generally divide ice machines into particle ice machines, sheet ice machines, plate ice machines, tube ice machines, shell ice machines, and so on based on the shape of ice.
