Why Fisheries and Port Ice Systems Need Upgrading

In many coastal regions, traditional ice plants face increasing operational pressure due to rising demand and aging refrigeration infrastructure.

1. Fisheries and seafood processing

Ice supply is often unstable during peak fishing seasons

Inconsistent ice temperature affects seafood freshness

Higher spoilage rates during storage and transport

2. Port terminals

Seasonal peak demand leads to ice shortages

Existing ice plants have limited production efficiency

Equipment aging increases downtime risk

3. Old ice plant renovation

Traditional ammonia systems require high maintenance

Risk of refrigerant leakage increases with aging pipelines

Environmental regulations are becoming stricter

Upgrading safety and compliance is a key requirement

Technical Specifications

Core System Functions

Stable High-Capacity Ice Production

The system is designed for continuous operation under industrial load conditions, supporting stable ice output during peak fishing and logistics periods.

Bitzer Compressor Performance

The refrigeration system uses industrial-grade Bitzer compressors designed for long-duration operation.

Key characteristics include:

Stable performance under low-temperature conditions

Designed for continuous industrial duty cycles

Built-in protection and fault detection functions

Freon Refrigeration System

The system adopts a Freon-based refrigeration cycle designed to meet modern environmental compliance requirements.

Benefits include:

No ammonia leakage risk

Easier system management

Lower operational safety complexity

Compliance with international environmental standards (such as EU F-Gas requirements)

Modular Retrofit Design

The system is designed for ice plant renovation projects.

In many cases:

Existing plant structures can be retained

Only refrigeration core and piping system are upgraded

Installation time and construction cost are reduced

This makes it suitable for aging ice plants seeking modernization without full reconstruction.

Application Scenarios

Fisheries and Seafood Processing

Fish preservation after landing

Temporary seafood storage

Cold chain pre-cooling

Saltwater block ice provides stable low-temperature storage conditions for seafood products during handling and transportation.

Port Terminal Operations

Bulk ice supply for fishing fleets

24-hour continuous ice production

Seasonal demand balancing

The system is suitable for ports requiring stable ice supply during peak fishing seasons.

Ice Plant Retrofit Projects

The system can be integrated into existing facilities for:

Replacement of ammonia refrigeration systems

Safety upgrades

Capacity expansion

Energy efficiency improvement

Retrofit projects typically reduce reconstruction cost compared to full plant replacement.

Why Saltwater Block Ice Is Used in Fisheries

Saltwater block ice is commonly used in marine environments due to its stable cooling performance.

Key advantages include:

Lower freezing point compared to freshwater systems

Slower melting rate in outdoor conditions

Better suitability for bulk seafood storage

Stable cooling during transportation

Retrofit Advantage: Ammonia to Freon Conversion

Many traditional ice plants use ammonia-based systems.

However, aging systems present challenges:

Higher maintenance requirements

Leakage risk in old pipelines

Increasing regulatory pressure

The CBFI retrofit solution allows:

Retention of existing plant structure

Replacement of core refrigeration system only

Reduced reconstruction cost

Improved operational safety

Process Technology Overview

The saltwater refrigeration system operates through a standard vapor compression cycle:

Compressor → Condenser → Expansion Valve → Evaporator → Ice Formation → Cycle Repeat

This process ensures continuous ice block production with stable thermal performance under industrial operating conditions.

Compared with traditional systems, Freon-based designs simplify maintenance and reduce operational complexity.

System Scalability

The system supports modular expansion.

Base capacity: 60 tons/day

Expansion potential: up to 100 tons/day

Modular refrigeration units can be added based on demand growth

This allows gradual investment scaling for ports and ice plant operators.

Frequently Asked Questions

Can the system be used for old ice plant renovation without full demolition?

Yes. In most retrofit projects, the existing structure can be retained. Only the refrigeration system and key piping are replaced, reducing overall reconstruction cost.

Can 60 tons/day meet port peak demand?

For medium to large fishing ports, 60 tons/day is typically sufficient for daily operations, with modular expansion available for peak seasons.

Is Freon refrigeration easier to operate than ammonia systems?

Yes. Freon systems generally require less operational complexity and have lower leakage risk compared to traditional ammonia systems.

Does the system support automation?

Yes. The system uses PLC-based automatic control and can be integrated into centralized monitoring systems for ice production management.
