A method for preparing a fish product. In the method, a slaughtered fish is filleted in pre-rigor state, skin is removed from the fillet in pre-rigor state, the skinless fillet is arranged in a pre-salting process in pre-rigor state and allowed to remain there for the pre-salting period, the fillet is removed from the pre-salting process, the fillet is arranged in its transport package, in which it is subjected to a second salting process, and the fillet is allowed to remain in the transport package for at least one day.

A method and apparatus for filleting fish to produce high yielding fillets from relatively short bodied fish in the size range of about 600 grams to about 3.5 kilograms dependent on species. The method and apparatus are designed to be capable of handling salmon, tilapia, trout, arctic char, barramundi, snappers, walleye pike, striped bass and similar species where the rib follows the contour of the belly cavity. Further, the method and apparatus incorporate belly opening and eviscerating components prior to subjecting the fish to a backbone removal system so that the fish need only be headed, but not gutted, before introduction into the machine.

Filleting apparatus cutting fish fillets from flank bones. The fish fillets been processed by a ventral knife assembly and a dorsal knife assembly. A conveying apparatus, transporting fish tail-first in transport direction, having an endlessly circulating transport conveyor with at least one transport saddle receiving/securing a fish, a flank knife assembly with two flank knife units, opposing each other on both sides of the transport conveyor in the region of a transport saddle guide. Each flank knife unit has a rotatably drivable circular knife and counter-surface arrangement Circular knife is arranged at a distance from the counter-surface arrangement to form a cutting gap and a control device moves flank knife units relative to the transport conveyor from standby position into working position and back. The counter-surface arrangements vary the size of the cutting gap controllably during the processing operation.

This disclosure concerns methods for processing and grading food articles including x-raying the food articles a first time and taking a 3D image of the food articles.

Apparatus for removing pin bones from fish fillets includes at least one pin bone removal device and a conveying device configured to convey the fish fillets past the at least one pin bone removal device. The pin bone removal device utilizes a rotationally driven profiled roller and a counter-bearing element. A clamping gap is formed between the rotationally driven profiled roller and the counter-bearing element. A control is configured to control a relative movement between the rotationally driven profiled roller and the counter-bearing element. The pin bone removal device is configured to grasp and remove the pin bones via tensile force from the fish fillets in the clamping gap.

A cutting apparatus for cutting an essentially V-shaped strip from meat products fed in a transport direction has a knife carrier to which two knife units are assigned. Each knife unit has a circular knife and a drive for rotationally driving the circular knife about a central axis of rotation. The two circular knives are set substantially in a V-shape to each other in a position enclosing an angle. An adjustable arrangement of the knife units provides for setting of the size of the angle. The offset of the two central axes of rotation to each other is equal to zero in the transport direction and the two knife units are adjustable exclusively synchronously with each other. A corresponding apparatus and method for cutting an essentially V-shaped strip from meat products fed in transport direction is also provided.
