1. Marine-Grade Structural & Material Design
1) Corrosion-Resistant Construction System
The machine structure is built using a hybrid corrosion-resistant architecture:
Stainless steel structural framework
Anti-corrosion aluminum alloy components
Surface anti-salt-spray treatment process
This configuration significantly improves resistance to:
Seawater corrosion
Salt mist erosion
Long-term high humidity degradation
Ensuring stable service life in offshore operating environments.
2) Heavy-Duty Refrigeration Power System
The system integrates industrial-grade refrigeration components optimized for marine operation:
Piston compressor with reinforced oil management system
Marine-grade seawater condenser (high-salinity compatible heat exchange design)
Impact-resistant valve plate assembly for liquid slug protection
Key operational advantages:
Stable performance under vessel tilt conditions (up to ~30° operational tolerance)
Reduced vibration-induced mechanical fatigue
Improved reliability under continuous load cycles
3) Modular Marine-Adapted Structure
The system adopts a fully welded modular design, optimized for offshore installation constraints:
No complex on-site assembly required
High structural rigidity for shipboard vibration environments
Simplified maintenance access for offshore service conditions
Reduced footprint for limited vessel engine room space
2. Flake Ice Engineering Characteristics
1) Physical Ice Properties
Ice form: irregular flake structure
Thickness: 1.5–2.5 mm
Stable temperature: approximately -8°C
This structure provides rapid and uniform cooling performance for perishable goods.
2) Functional Advantages
1. High Heat Exchange Efficiency
Large surface-area-to-volume ratio enables rapid thermal absorption, significantly improving cooling speed compared with conventional block or cube ice.
2. Dry and Non-Clumping Behavior
Flake ice maintains low free-water content, preventing agglomeration during storage and transport, ensuring stable flowability for automated distribution systems.
3. Product Protection Design
Rounded, non-sharp morphology prevents mechanical damage to seafood surfaces during direct contact, preserving product integrity and market appearance.
4. Flexible Water Source Adaptability
Supports both:
Freshwater ice production
Seawater direct ice production (for offshore operation)
This allows continuous operation across offshore and coastal environments without infrastructure dependency.
3. Application Scenarios
1) Fisheries & Offshore Operations
Immediate post-catch cooling on fishing vessels
Port-side temporary storage of aquatic products
Cold chain temperature maintenance during unloading and transport
2) Seafood Processing & Distribution
Pre-cooling of raw seafood materials
Processing plant temperature control
Fresh product distribution logistics
3) Retail & Commercial Cold Chain
Seafood display preservation in supermarkets
Fresh food counters and wet markets
Short-cycle retail refrigeration support
4) Industrial Cooling Applications
Concrete cooling in construction projects
Hydration heat control in large-scale pouring
General industrial low-temperature process support
4. Engineering Positioning
The CBFI 20T flake ice machine is designed as a marine-adapted industrial cooling unit, focusing on:
Corrosion resistance under high-salinity environments
Operational stability under mechanical motion conditions
Continuous high-load ice production capability
Efficient thermal exchange for rapid cooling demand
It is positioned as a core infrastructure component for modern fisheries cold chain systems rather than a standalone ice-making device.
