Portioning and sizing salmon fillets
This solution is designed for the fish industry, particularly for portioning salmon and other types of fish fillet.
The system is suitable for fish processing plants that produce retail fixed weight portion packages.
Suitable for high capacity production of fish portions, e.g. salmon portions, where high yield utilizations is the number one priority. This system affords perfectly accurate production of fish fillets into multiple portion sizes. When portioning large fish fillets, it is important to be able to select the middle of the portions for each fixed weight tray (either individual pieces or rows of pieces), and use head and tail portions for other pack sizes.
A Dual lane 520 Process Weigher is placed in front of the ScanCut225D PortionCutter. The weighing unit gives a weight input to the portion cutter in order to calculate the exact density of each individual whole fillet before the cutting process begins. The purpose of this is to maintain weight accuracy even if the density of the raw material varies. Density can vary because of differences in things such as the fat percentage in larger fillets. The relative amount of tissue (e.g. fat content) of different densities can change significantly over a short period of time e.g. due to water temperature, size of fish, availability of food, nutrition and the developmental status of the fish. By combining weighing and scanning results the portion cutter is able provide a very high yield utilization of the raw material.
After the cutting, the different cuts are sorted in fixed weight portions (e.g. 125g) that go directly to the packing machine. Trim, tail and head portions are individually sort via the Dual Speed-drop sorter.
Scope of delivery
The system is designed to cut fresh boneless fish fillets into portions using a Scanvaegt ScanCut 225D PortionCutter, Dual Speed-drop and Dual SP520 Process Weigher.
The system offers high capacity and perfect fish fillet cut accuracy. Using a Dual SP520 Process Weigher to give input to the ScanCut225D PortionCutter prior to cutting makes the final portions even more accurate. The weighing data, used in conjunction with the scanning results, makes it possible to adjust for raw material density.
The line is also available in single lane version with SP520 Process Weigher, ScanCut 225S and SpeedDrop225S.
SP520 Process Weigher
Featuring a robust and reliable design that can withstand use in even the harshest of production environments, Scanvaegt’s Dual SP520 Process Weigher is the ideal solution for the weighing of raw material in the wet food industry.
The ScanCut 225D PortionCutter is the ultimate dual lane, high-speed cutting machine for lean production of fish. With a cutting frequency of up to 2,170 strokes per minute/lane, ScanCut 22SD produces precise, fixed-weight portions while reducing give-away and maintaining a high yield-percentage. The portion cutter makes it possible to combine several cutting jobs, achieving the best possible yield utilization - e.g. by using the middle part of the large fillet for individual fixed weight portions or a fixed number of pieces into fixed weight. The head and tail can be fixed weight or trim depending on demand.
Scanvaegt SpeedDrop 225D
The dual speed-drop is controlled by portion cutters and can control up to six different types og jobs. It features a high-speed servo driven retraction function, which allows up to 130 portions to be sized out individually. The illustrated product take away located after the speed drop is not included.
