Industrial fish belly opening machine with precise positioning system, 60–80 fish/min capacity. Arc-shaped stainless steel blade, low fish damage, supports fresh or thawed fish. Ideal for seafood preprocessing factories and automated fish processing lines.
In modern seafood processing plants, fish belly opening is a critical preprocessing step that directly affects gutting efficiency, product appearance, food safety, and overall production yield. Traditional manual belly opening is labor-intensive, inconsistent, and prone to meat damage—especially when handling medium and large fish in high volumes.
The Automatic Fish Belly Opening Machine is designed to solve these challenges by delivering high-speed, standardized, and precise belly opening for a wide range of fish species. With advanced positioning technology, arc-shaped stainless steel blades, and adjustable processing parameters, this machine has become a core unit in industrial fish preprocessing lines worldwide.
Manual belly opening often leads to:
Inconsistent cutting depth
Damage to fish meat and abdominal cavity
High labor dependency and rising labor costs
Difficulty in meeting hygiene and food safety standards
By contrast, an automatic fish belly opening machine ensures:
Uniform cutting results
Higher processing speed
Reduced raw material loss
Improved downstream gutting and washing efficiency
This fish belly opening machine is specifically engineered for medium to large-scale seafood processing factories, handling both fresh and thawed fish with minimal damage.
60–80 fish per minute
Equivalent to 5–8 skilled workers
Stable performance during continuous operation
Weight range: 200 g – 2000 g
Fish height: ≤ 10–20 cm
Larger sizes available through customization
Tilapia
Red fish
Yellow croaker
Sea bream
Cod
Perch
Crucian carp
Custom settings can be optimized for different fish body structures.
The machine uses a food-grade rubber conveyor belt with anti-slip textured surface. This ensures stable transport of fish with different body shapes and sizes, preventing deviation or misalignment during processing.
The cutting blade is the heart of the machine:
Made from high-hardness stainless steel
Arc-shaped design conforms to fish abdominal anatomy
Ensures complete belly opening without penetrating deep into muscle tissue
For different fish species and sizes, operators can adjust blade parameters to achieve optimal results.
Some advanced configurations include pressure sensing technology:
Automatically slows down when detecting hard structures such as fish bones
Reduces blade wear
Minimizes meat damage
Extends equipment lifespan
Once fish are placed head-first into the feeding inlet:
Conveyor transports fish to positioning area
Sensors detect belly location
Cutting system performs precise belly opening
Internal washing system removes blood and impurities
Fish exits ready for gutting or further processing
Depending on processing requirements, the machine supports:
Hook blade cutting
High-pressure water-assisted opening
These methods ensure flexibility across different fish types and production goals.
60–80 fish/min throughput
Supports large-scale continuous processing
