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.

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.

The present invention provides a new method and apparatus for performing water jet cutting of food items on conveyor belts. The invention provides a cutting unit with a novel design and a method for the use of plurality of cutting devices for cutting, trimming and removing undesired tissue from food items in a more accurate but faster way than prior art methods.

The invention relates to an apparatus, designed and configured for the removal of pin bones from a fish fillet that has been completely separated from the skeleton, comprising a tool having a clamping mechanism for clamping and releasing individual pin bones, a drive for the rotary driving of at least parts of the clamping mechanism and means for transmitting the rotational movement from the drive to the clamping mechanism, which is characterized in that the clamping mechanism comprises a base body that can be driven such that it rotates about a rotational axis, with which at least two clamping jaws are associated, which clamping jaws define a resulting central axis M and are for clamping and releasing the pin bones, wherein the clamping jaws are designed and configured such that they can move towards and away from one another, and the drive is designed and configured for exerting an oscillating rotational movement of the base body about the rotational axis and thereby of the clamping jaws about the central axis M. The invention further relates to a corresponding method.

This invention relates to a cutting system for cutting food products while the food products are conveyed by a conveyor. An arc-shaped system and a cutting means are provided, where the cutting means is adapted to be connected to the arc-shaped system. The arc-shaped system is adapted to be positioned above a surface area of the conveyor on which said food products are resting during the cutting such that the center of the arc-shaped system is around the surface area. A control unit operates the position of the cutting means within the arc-shaped system based on image data.

An apparatus and method for removing pin bones from fish fillets includes at least one pin bone removal device and a conveying device designed to convey the fish fillets past the at least one pin bone removal device. The pin bone removal device includes a rotationally driven profiled roller having a counter-bearing element forming a clamping gap, the roller and the counter-bearing element being designed to grasp the pin bones in the clamping gap by clamping and to remove the bones from the fish fillets by applying tensile force. The counter-bearing element and the roller are designed to be controllably moved with respect to each other by a controller.

A system for fish processing can include: a fish fixturing subsystem, a tooling subsystem, an analysis subsystem, and/or any other suitable components, which can optionally be part of a fish processing subsystem. Additionally or alternatively, the system can optionally include: an intake subsystem, an expulsion subsystem, and/or any other suitable components.

The present invention relates to an improved method and a device for mechanically filleting and removing pin-bones from gutted fish using conventional filleting devices, where the fish rests on a saddle on a conveyor using pairs of circular knives to separate the fillet from the backbone. The apparatus and method are designed to facilitate mechanical filleting and pin-bone removal of gutted fish with the head intact. The present invention provides a more accurate method of positioning the pin-bones in the gutted fish.
