In the vast world of ice production, industrial tube ice makers stand out as a pivotal technology, ensuring a steady supply of ice for various applications. From preserving seafood to cooling concrete, these machines are indispensable in industries where ice is not a luxury but a necessity.
What is an Industrial Tube Ice Maker?
An industrial tube ice maker is a specialized machine designed to produce cylindrical ice, commonly referred to as tube ice. These tubes are typically hollow, with an outer diameter ranging from 22 to 41 millimeters and lengths of 25 to 42 millimeters. The hollow structure of the ice allows it to freeze more uniformly and melt more slowly compared to solid ice, making it highly efficient for widespread use.
How Does It Work?
The process of making tube ice involves several steps, all executed within the confines of the industrial ice maker:
-
Water Circulation: Water is pumped into a vertical stainless steel cylindrical evaporator. The water flows over the inner surface of the evaporator, which is maintained at a temperature below freezing by the refrigerant flowing through the evaporator’s outer shell.
-
Ice Formation: As the water circulates, it gradually freezes onto the inner walls of the evaporator. The controlled environment ensures the ice forms uniformly, creating the tube shape with a hollow center.
-
Harvesting: Once the ice reaches the desired thickness, a hot gas (usually refrigerant in a gaseous state) is introduced into the evaporator. This melts the inner surface of the ice tubes slightly, causing them to loosen and fall into a storage bin or conveyor system.
-
Separation and Storage: The ice tubes are then separated based on size and stored in insulated bins to prevent melting. They are now ready for use or packaging.

Applications of Tube Ice
Tube ice’s unique properties make it suitable for a wide range of industrial applications:
- Food Preservation: In the seafood and meat industries, tube ice is used to maintain freshness during transportation and storage.
- Beverage Industry: Tube ice is popular in bars and restaurants because it melts slowly, keeping drinks colder for longer without diluting them quickly.
- Concrete Cooling: In large-scale construction projects, tube ice is added to concrete mixes to regulate the temperature and prevent cracking during curing.
- Medical and Chemical Industries: Tube ice is used in laboratories and medical facilities for various cooling needs, including the storage and transport of medical supplies and samples.
Advantages of Tube Ice Makers
Industrial tube ice makers offer several benefits that make them a preferred choice in various settings:
- Efficiency: They produce large quantities of ice consistently and quickly.
- Durability: These machines are built to withstand continuous operation and harsh environments.
- Energy Savings: Modern tube ice makers are designed to be energy-efficient, reducing operational costs.
- Quality: The ice produced is clear and pure, as the freezing process removes impurities.
Conclusion
Industrial tube ice makers are a cornerstone in industries where ice is a critical component. Their ability to produce large quantities of uniform, slow-melting ice makes them essential for food preservation, beverage service, construction, and more. By understanding the functionality and applications of these machines, businesses can better appreciate their role in maintaining efficiency and quality in their operations.
