Tube Ice Making Process

※ 1Cycle : average 12minutes [freezing 10min, harvest 2min]  



1. Tube-ice is frozen on the inside of vertical stainless steel tubes by refrigerant circulating in the surrounding shell.

2. A film of water falls from the top of each tube, freezing from the outside in.

3. As the water freezers, salts and impurities are washed back to the pumping tank for automatic removal. 

4. When the ˝tubes˝ of ice have frozen to the desired thickness, the cycle is reversed and hot gas from the condenser is introduced into the refrigerant in the shell, releasing the ice.

5. The Tube-Ice falls into a rotating cutter which cuts uniform ice tubes to desired lengths.
