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. |
