Ice Through History
The Fascination of Ice Storage
New technology for an old idea
From ancient roots to modern application
Since ancient times, humanity’s use of ice has been rooted in the rise of civilization. As early as 5,000 years ago, the Chinese pioneered the use of ice cellars to preserve food and craft cold delicacies. For millennia, ice was a gift of nature—harvested in winter, stored for summer—a tradition that endured from the Xia and Shang dynasties all the way to modern times.
Today, with the leap forward in modern ice-making technology, we have not only broken free from the constraints of season and geography—enabling ice to be produced anytime, anywhere—but we can also produce high-performance, high-quality ice slurry through cutting-edge techniques such as supercooling technology, offering broader applications and superior performance
The Principle of Supercooled Water Ice Slurry Technology
- Water circulates through high‑efficiency heat exchanger, precisely supercooled,then destabilized to produce ice slurry
- Water is cooled below 0°C in a special heat exchanger (deeper supercooling = more ice per cycle). A controlled disturbance (mechanical/ultrasonic) breaks the meta‑stable state, instantly generating micro‑ice crystals. The slurry is pumped to storage tanks and can be directly extracted for cooling
Why choose the supercooled water method?
Eliminate ice blockage and mechanical scraper maintenance forever.
Supercooled water
- Evaporation -3~-5°C → COP >30% improvement
- No moving parts in ice generator, near‑zero maintenance
- IPF >50% saturated slurry
- Destabilization inside single vessel, zero ice blockage
- Plate heat exchanger ΔT only 0.5°C
Traditional methods
- Scraped surface: mechanical failures, limited scale
- Step‑wise supercooling: temp must be -3±0.5°C → frequent blockage
- Evaporation temp typically -15~-30°C
- Low ice yield per cycle
- Vacuum methods: high energy, complex system
Key metrics
- Energy use: supercooled ~15 kJ/kg vs traditional >30 kJ/kg
- Crystal size: ~50 μm, pumpable vs flake/block ice needs crushing
- Reliability: 2000h+ continuous (verified prototype)
