Understanding Tube Ice Technology: The Manufacturing Process

The production of tube ice involves a sophisticated, continuous refrigeration cycle designed for optimal efficiency and ice purity. Understanding this process is crucial for evaluating any tube ice machine for sale.

Detailed Process Flow:

1. Water Supply and Pre-treatment: Potable water, often pre-filtered or softened to remove impurities and minerals, is supplied to the water distribution tank. This pre-treatment is vital for producing clear, hard ice and extending the service life of the machine’s components by minimizing scale build-up.
2. Refrigeration Cycle Initiation: The core of the system is a robust refrigeration unit, typically utilizing a high-efficiency screw or reciprocating compressor. The refrigerant (e.g., Ammonia, R404A, R507A) is compressed, condensed in an evaporative or air-cooled condenser, and then expanded through a throttle valve, leading to a significant temperature drop.
3. Ice Formation in the Evaporator: The super-cooled refrigerant circulates within the jacket of the vertical tube evaporator. Water from the distribution tank is continuously pumped upwards and flows downwards along the inner surface of the evaporator tubes. As the water passes over the cold surfaces, it gradually freezes, forming cylindrical ice layers within the tubes. The unique vertical design ensures efficient heat exchange and uniform ice growth.
4. Hot Gas Harvest (Defrost): Once the ice tubes reach the desired thickness, a pre-programmed hot gas defrost cycle is initiated. Hot refrigerant gas from the compressor bypasses the condenser and is directed into the evaporator jacket. This causes a slight warming of the tube surfaces, allowing the ice tubes to detach and fall under gravity into an ice cutter.
5. Ice Cutting and Discharge: The fallen ice tubes are then precisely cut into uniform lengths (typically 28mm, 34mm, or 40mm in diameter, and 25-50mm in length) by a rotating cutter blade. The cut tube ice is then discharged into an insulated storage bin or directly conveyed to its application point.
6. Automated Control System: A Programmable Logic Controller (PLC) monitors and controls all aspects of the process, ensuring optimal performance, energy efficiency, and safety. This includes temperature regulation, water flow, ice thickness, and harvest cycles.
