Tube ice is a kind of hollow cylindrical ice with external diameter ø21、ø28、ø34mm and length 25～42mm. The hole diameter is usually ø5～10mm and it can be adjusted according to ice making time.
Features: Tube ice is thick and transparent with long storage period. It isn't likely to melt in a short time.
Application: Daily eating, keeping vegetable and seafood fresh, etc.

As shown, when the refrigeration system begins operating normally, the water in the tank below is transported from the water outlet to the water inlet of upper water tank by the water pump. After the water goes across the distributive pipe, it downwardly flows along the wall of the heat exchange tube. The water then begins a heat exchange with the refrigerant outside heat exchange pipe, which lowers the temperature. Some of the water is formed into tube ice, while the water which does not become ice returns to the low water tank. The water continues circulating so that the ice gets thick, and the hole of tube ice also becomes smaller and smaller.
After a period of time, water stops circulating and the refrigeration system changes into ice cutting mode. The ice cutting framework then begins to operate. The surface of the heat exchange pipe consists of refrigerant hot gas with high-pressure. The hot gas begins a heat exchange with the tube ice in the pipe wall. Hot gas makes contact between the tube ice and the wall of heat exchange, thawing the ice so that it looses adhesive force. The ice then drops into an ice cutting framework because of gravitational force and finally is cut into many pieces of tube ice.
