The ice maker is a refrigeration mechanical device that generates water by cooling the refrigerant from the refrigerant of the refrigeration system through the evaporator. The refrigeration system uses a water carrier to produce ice after passing through a certain device under the energization state. According to the principle of the evaporator and the production method, the shape of the generated ice cubes is also different; generally, the ice machine is divided into a particle ice machine, a flake ice machine, a plate ice machine, a tube ice machine, a shell ice machine, etc. in the shape of ice.
