Status: USED
The Marel MS 2612 (historically developed alongside Carnitech) is an industry-standard, high-speed pinbone remover designed specifically for whitefish, salmon, and trout processing. It relies on a mechanical roller and clamping jaw mechanism to gently grip and extract pinbones from fresh fillets, prioritizing minimal meat damage and maximum yield retention.
Key Specifications & Layouts
The MS 2612 is highly scalable, ranging from small standalone single-lane machines to high-throughput six-lane industrial variants integrated directly into automated trimming lines.
| Model / Configuration | Lanes / Heads | Max Throughput (Fillets/Min) | Water Consumption | Dimensions (W×L) |
| MS 2612.00 / .10 | 1 Lane / 1 Head | Up to 18 | 5 L / min | 710 X 1650 mm |
| MS 2612.25 / .30 | 2 Lanes / 2-3 Heads | Up to 36 | 10 L / min | 1000 x 1650 mm |
| MS 2612.40 | 4 Lanes / 4 Heads | Up to 72 | 20 L / min | 1700 x 1650 mm |
| MS 2612.60 | 6 Lanes / 6 Heads | Up to 108 | 30 L / min | 2560 x 2240 mm |
Core Engineering Features
- Residual Meat Preservation: Fillets travel skin-side down on a conveyor belt. The processing head gently holds the meat in place while a mechanical «bone raiser rake» lifts the buried bone tips into a synchronized rotating roller and clamping jaw setup, cleanly pulling them out.
- Variable Control System: Operators use an integrated touchscreen interface to adjust the belt speed (optimally calibrated around 4–5 meters/min), head speed, and mechanical extraction pressure to match changing fish sizes, seasons, or texture changes (such as post-rigor vs. fresh states).
- Sensors for Water Economy: Instead of keeping wash-down water running continuously, the MS 2612 features built-in product detection sensors. The spray nozzles only activate when a fillet is physically approaching the head, significantly dropping total processing utility costs.
- Sanitary IP65 Design: Built from heavy-duty stainless steel with an open frame structure. Conveyor belts are outfitted with tool-free, quick-release tension latches so that washdown crews can strip and clean the inner mechanics efficiently.
Technical Note on Maintenance: If you are servicing an existing unit, standard configurations utilize specialized mechanical components like the HTD timing belts (e.g., 635-5M-15) and unique counterweighted mechanical head assemblies to maintain uniform contact force over irregular fillet heights.
