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 characterised 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.

The invention relates to a method for mechanically recovering flesh from fish, in which by introducing incisions, the dorsal bones and the ventrally directed bones are cut free from the laterally located fillets without separating the pin bones from the spine and the separating gaps formed by the incisions are then expanded, thereby moving the lateral fillets away from the spine of the fish in the lateral direction transverse to the dorsal bones, wherein the fillets are peeled away from the pin bones extending laterally out from the spine or the flank bones, and a corresponding apparatus for mechanically recovering the flesh of fish.

A knife assembly for performing, for example, a filleting cut on a slaughtered and gutted fish has at least one cutting head. The cutting head has at least one housing with a knife unit and a drive unit for rotationally driving a knife shaft rotatably borne inside the housing. A separating knife is arranged on a free end of the knife shaft for conjoint rotation. The knife shaft is axially movable relative to the housing and is configured to be decouplable from the drive unit for the purpose of axially moving the knife shaft in such a way that rotational movement of the knife shaft can be performed independently of the axial movement of the knife shaft. An apparatus and a method are disclosed.

A pin bone removal system involves automatically removing a pin bone area of a fish fillet when conveyed by a conveyor after undergoing a cutting process, and includes at least two side by side arranged conveyor belts extending from a first end for receiving a fish fillet to a second end. The internal arrangement of the side by side arranged conveyor belts is such that the spacing varies among first end the conveyor belts along their length. The transversal position of the fish fillet in relation to the first end is adjusted when the fish fillet arrives at the downstream position such that the position of the cut pin bone area is such that the cut pin bone area falls through the space while the remaining part of the fish fillet remains on the first and/or second conveyor belts.

Methods and systems for processing fish, such as salmon, are provided which enable filleting of the fish in a particular efficient manner. An example method includes exposing a backbone of a fish from a belly side of the fish, positioning the backbone of the fish on a conveyor device, and conveying the fish with the backbone in contact with the conveyor device. The conveyor may be a spiked chain, and positioning the backbone of the fish on the conveyor device may include engaging the backbone of the fish with the spiked chain such that the fish straddles the spiked chain as the fish is transported. The method may further include cutting the fish from the dorsal side on each of opposing sides of a central plane of the fish to a location adjacent a connection of the pinbones of the fish with the vertebrae of the fish while the fish is conveyed with the backbone in contact with the conveyor device, and subsequently peeling the ribs and ventral spines from fillets of the fish.

The present invention relates to a fish bone removal apparatus comprising a frame (1), a picking member (9) rotatably mounted in relation to the frame about a rotational axis (3), and an actuator arranged to rotate the picking member in a rotational direction. The picking member comprises a first and a second rotating element (10, 12) arranged to form a wedge-shaped gap (24) between them for receiving a bone. The wedge-shaped gap is tapered in a direction opposite the rotational direction of the picking member. The first rotating element is disc shaped and has two parallel radial surfaces and an outer circumferential surface (11c). The second rotating element (12) comprises a bent elongated body having a periphery with a bending radius corresponding to the bending radius of a periphery of the first rotating element, two radial surfaces and an outer circumferential surface (22). The radial surfaces of the first rotating element are arranged in parallel with a plane perpendicular to the first rotational axis, and the radial surfaces of the second rotating element are arranged angled to said plane, so that the outer circumferential surface (22) of the second rotating element is tapered in the rotational direction of the picking member. The first and second rotating element are disposed so that one of the radial surfaces of the first rotating element faces one of the radial surfaces of the second rotating element, and so that the periphery of the first rotating element and the periphery of the second rotating element are positioned on the same distance from the first rotational axis.

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.

The invention relates to an apparatus for removal of pin bones from fish meat, preferably from a fillet of white fish, comprising a frame for supporting a drive device and a rotatably driven member driven by drive device, the rotatably driven member being provided with engagement means, and a counter pressure element for providing a clamping function between the counter pressure element and the rotatably driven element. The rotatably driven member has a curved convex engagement surface directed towards the fillet and adapted to match the shape of said fillet where the pin bones are located when the fillet is lying on a flat surface.
