Introduction
Tube ice machines are the backbone of industries requiring durable, slow-melting ice—from seafood processing to pharmaceutical cooling. Ice Pecold’s systems combine precision engineering and energy-efficient refrigeration to produce high-quality ice tubes. This guide dives into the working principles, technical specifications, and real-world applications of these machines, answering both technical and commercial questions for buyers worldwide.
1. The Science Behind Tube Ice Formation
Core Mechanism: The Freeze-Release Cycle:
A tube ice machine operates through a continuous freeze-release process:
- Water Distribution:
23°C water is sprayed evenly onto the inner walls of vertically aligned stainless steel tubes (φ22mm, φ29mm, or φ35mm).
- Outward-In Freezing:
Refrigerant (R404A/R22) circulates outside the tubes at -15°C evaporating temperature, extracting heat and forming ice from the tube wall inward.
Physics Insight: Heat flux follows: Q=(k⋅A⋅ΔT)/ L, ensuring rapid, uniform freezing.
- Harvesting:
Warm refrigerant gas (3°C) briefly melts the ice-tube interface, allowing ice cylinders to slide into storage bins via gravity.
Cycle Time: 15–30 minutes, enabling 24/7 production (3–100 tons/day).

FAQ Section
Q: How long does tube ice last compared to flake ice?
A: Tube ice melts 3x slower (2–6 hours vs. 30–40 minutes) due to dense, low-surface-area design.
Q: Can the machine operate in coastal environments?
A: Yes—opt for 316L stainless steel tubes and anti-corrosion coatings.
Q: What’s the ROI for a 20-ton/day machine?
A: Most clients recover costs in 18–24 months via energy savings and reduced waste.
