Modern salmon processing is facing increasing challenges related to maximizing raw material utilization, maintaining consistent fillet quality, and managing rising production costs. In a highly competitive market, even small differences in meat yield or process consistency can directly impact the profitability of the entire processing plant.
As a result, more and more processing facilities are investing in automatic filleting technologies that improve process control, reduce raw material losses, and maintain uniform product quality. One such solution is the Marel MS 2730, a system specifically developed for industrial salmon filleting.
Filleting technology focused on higher yield
One of the key elements of the system is the way the fish is handled during the filleting process. The salmon is fed into the machine belly down, which improves product infeed and increases overall process stability.
An additional set of circular knives performs a cut from the belly area to the tail, allowing more meat located close to the backbone to remain in the fillets. This feature has a direct impact on improving fillet yield.
In practice, this means:
✔ better raw material utilization
✔ reduced meat losses
✔ more precise cutting performance
✔ higher filleting consistency
Automatic adjustment to fish size
One of the most innovative features of the Marel MS 2730 is its ability to automatically adjust filleting parameters according to the size and profile of each fish.
The built in measuring system analyzes the salmon’s profile and size, while electronically controlled cutting tools automatically adapt the filleting program to the fish’s shape and dimensions. As a result, the machine maintains high cutting precision without the need for manual adjustments.
This solution allows:
✔ maintaining stable fillet quality
✔ increasing process efficiency
✔ improving yield across different fish sizes
✔ reducing downtime related to machine adjustments
This technology also enables high precision filleting both immediately after slaughter and at later stages of raw material processing.
Industrial production performance
MS 2730 może przetwarzać do 25 ryb na minutę, w zależności od ich długości. Przy dużych wolumenach produkcji stabilność procesu oraz możliwość utrzymania jednolitych parametrów filetowania stają się kluczowe dla efektywnego zarządzania produkcją.
Automatyzacja procesu pomaga:
✔ zwiększyć przepustowość linii
✔ ograniczyć wpływ pracy manualnej
✔ poprawić przewidywalność produkcji
✔ utrzymać jednolity standard jakości filetów
Automatic back and belly trimming as an additional option
The Marel MS 2730 can also be additionally equipped with an automatic back and belly trimming system.
At the infeed, the machine measures the height of each fish, while sets of circular knives perform trimming cuts according to pre selected parameters. This helps maintain a consistent fillet finish while reducing the amount of manual labor required on the production line.
This solution allows:
✔ improving fillet appearance
✔ increasing consistency of the final product
✔ reducing manual trimming costs
✔ improving production workflow organization
✔ maintaining uniform quality standards
For many processing plants, technologies such as the Marel MS 2730 are becoming not only a method of automating filleting, but also a tool for improving yield, product consistency, and overall production efficiency.
With increasing production costs and growing pressure to maximize raw material utilization, automatic filleting technologies are becoming one of the key elements of modern salmon processing.
