Optimized yield

The PORTIO software for the Portion cutter always calculates the cuts so as to leave zero waste and maximize the yields. Conditional programs are possible for increased yields. Combinations of fixed thickness and various fixed weights allow portioning with a maximum yield for all fish applications.

Unparalleled accuracy

3 sets of laser camera, one on the top and 2 on the sides perfectly scan the more rounded fish fillets or whole fish. This transforms the shape of the fish product into a 3D model. As it knows the density of the fish, the intelligent software of the portioning machine instantly calculates where to cut the fish to obtain the target weights.

Modular belt

The portion cutter has automatic stretch compensation which guarantees optimum accuracy over the years, using the same belt. The unique belt surface that has been specially designed for fish products keeps the fillets in place and prevents them from moving during portioning.

Adding options

Specially designed options can be bolted on to the portioner at any later stage for specific applications. The density scale compensates for variation in injected or smoked fish fillets. The Automatic Product Holder prevents the crustfrozen fish fillets or big whole fish from moving during portioning. The retractable outfeed belt allows the head to be separated or the tail to be trimmed and can be combined with a blow-off system.

User-friendly software interface

Intuitive programming of cutting patterns and fast and easy fine-tuning of the programs to get the maximum yields. The cutting pattern is shown on the screen along with details of the thickness and the weight of each fish portion.


The MATRIX P software collects all production data from the PORTIO poultry cutting machine and allows production reports to be generated. MATRIX P enables users to remotely take programs offline and monitor the status of the fish slicer using an event log.                                                                                    

Extremely hygienic, easy to clean

The portion cutter complies with the most stringent hygiene standards. The open structure of the portioning machine for fish allows it to be fully cleaned using a pressure washer and disinfected on the inside and outside. A CIP (Cleaning In Place) system rinses the belts. All cabinets with electrics and electronics have a unique drying system to prevent the build-up of condensation. Belts can be removed with a quick release, without the need for tools.


The portion cutter can be connected to the internet. This enables the status of the fish slicer to be diagnosed from a remote service point.

Low noise

Operators appreciate the good working environment around the PORTIO, thanks to its low noise levels.
