Industrial automatic fish gutting, evisceration and washing machine for seafood processing plants. Capacity 60–80 fish/min, one-step belly opening, viscera removal and internal cleaning. Food-grade stainless steel, high hygiene, ideal for large-scale fish processing lines.
In modern seafood processing, fish belly opening, evisceration, and internal washing are among the most critical yet labor-intensive preprocessing steps. For decades, these operations have relied heavily on manual labor, resulting in inconsistent quality, low efficiency, hygiene risks, and rising production costs.
The Automatic Fish Gutting, Evisceration & Washing Integrated Machine is designed to fundamentally transform this stage of fish processing. By combining belly opening, viscera removal, and internal cleaning into one fully automated workflow, this machine delivers a standardized, high-efficiency, and hygienic solution from raw fish to semi-processed products.
It is an ideal choice for industrial fish processing factories, centralized preprocessing centers, and export-oriented seafood plants seeking to increase capacity while maintaining strict quality and hygiene standards.
In conventional processing lines, fish gutting and cleaning are usually performed manually or semi-manually, creating multiple challenges:
Inconsistent belly cutting depth damages organs and causes contamination
Incomplete viscera removal leaves black membrane and blood residue
Insufficient internal washing affects appearance and shelf life
Multiple workers required for sequential steps
High labor costs and difficulty scaling during peak seasons
Unstable product quality and hygiene risks
For factories processing thousands of fish per hour, manual methods quickly become a production bottleneck that limits throughput and increases operational risk.
Automation is no longer optional—it is essential for competitive seafood processing.
The Automatic Fish Gutting, Evisceration & Washing Machine introduces a “one-station processing” concept, integrating three critical operations into a continuous automated workflow:
Belly opening (precise cutting)
Internal organ removal
Thorough internal washing
This integrated approach eliminates manual handoffs between processes, significantly improving efficiency, hygiene, and consistency.
The feeding section uses a human-hand-simulation fixing mechanism that gently secures and positions fish of varying sizes.
Suitable for fish lengths 10–50 cm
Stable positioning ensures consistent processing
Prevents fish rotation or misalignment
Compatible with continuous conveyor operation
This ensures each fish enters the processing zone in the correct orientation.
The belly opening unit is equipped with a high-speed rotating food-grade blade:
Precise belly incision along the correct anatomical line
Consistent cutting depth
Avoids cutting fish bones or damaging flesh
Minimizes internal contamination
Compared with manual knife cutting, this system delivers uniform results regardless of operator skill.
After belly opening, the viscera removal system uses a combined mechanism of hook knife, rotating brushes, and water assistance to remove internal organs.
Rapid separation of viscera
Effective removal of black membrane and blood residue
Evisceration efficiency ≥ 99%
Minimal residue inside the abdominal cavity
This step ensures the fish interior is clean and ready for washing or further processing.
The final stage features a 360-degree rotating spray cleaning system:
High-coverage water jets reach all internal surfaces
Thorough removal of blood, mucus, and impurities
Improves hygiene and appearance
Prepares fish for cutting, filleting, or packaging
The washing system plays a critical role in extending shelf life and improving downstream processing quality.
Designed for high-volume processing environments, this machine delivers exceptional productivity.
60–80 fish per minute
2,000–2,500 fish per hour
Equivalent to 25–30 skilled workers
This allows factories to dramatically increase daily output while reducing labor dependency.
Fish species vary widely in body shape, internal structure, and size. A one-size-fits-all solution is rarely effective.
Fish weight: 200–2,000 g
Fish height: 10–20 cm
Customizable for larger fish sizes
Tilapia
Red fish
Yellow croaker
Sea bream
Carp, crucian carp, trout, and similar species
Adjustable blade position
Adjustable brush pressure
Adjustable processing speed
This modular adaptability ensures optimal performance across multiple fish types.
One of the biggest concerns in automated fish gutting is product damage.
This machine is engineered to be efficient yet gentle:
Controlled cutting depth prevents flesh damage
Brush-based evisceration avoids tearing
Water-assisted cleaning reduces friction
Maintains fish shape and integrity
As a result, processed fish maintain a clean appearance and high yield, suitable for premium markets.
The machine can process:
Fresh fish
Partially thawed frozen fish
Speed and pressure adjustments allow stable operation without compromising quality, making it suitable for different raw material conditions.
Entire machine constructed from 304 food-grade stainless steel
Corrosion-resistant and durable
Designed for wet processing environments
Smooth surfaces for easy cleaning
Efficient waste discharge
Reduced cross-contamination risk
Compatible with HACCP and GMP standards
This makes the machine suitable for export-oriented processing facilities.
