What Is a Direct Cooling Ice Block Machine?
A direct cooling ice block machine is an industrial ice production system where refrigerant directly cools the ice mold to form solid ice blocks.
Compared with brine-type systems, direct cooling technology simplifies the ice-making process and improves operational efficiency in continuous production environments.
The system is widely used in industrial sectors requiring stable and high-strength ice blocks for storage and transportation.

Why Fisheries and Food Industries Use Direct Cooling Ice Block Machines
1. Fisheries and ocean fishing operations
Fishing vessels require stable ice for long-duration storage of caught seafood.
In offshore environments:
Ice melting speed directly affects seafood freshness
Water from melting ice can impact storage hygiene
Long-distance transport increases ice demand
Direct cooling ice blocks provide higher structural strength, helping reduce melting loss during fishing and transport operations.
2. Food processing plants
Food processing facilities require continuous ice supply for:
Slaughtering operations
Meat cooling processes
Production line temperature control
Traditional ice systems may require frequent maintenance shutdowns, which can interrupt production flow.
Direct cooling systems are designed for continuous operation, supporting stable ice supply in high-demand environments.
3. Cold chain transportation
During long-distance transport, ice stability becomes critical.
Key requirements include:
Slow melting rate
Stable stacking structure
Reduced temperature fluctuation
Direct cooling ice blocks help reduce ice loss during transport and improve temperature consistency.
