1. Device for removing bones, preferably fish bones, from meat, comprising a rotatable internal drum (2), c h a r a c t e r i z e d i n that the rotatable internal drum (2) may rotate inside a second rotatably external drum (1), said drums (1,2) being formed by a number of ribs (4,9), there existing between these ribs (4,9) openings or slots for capturing bones, where the internal drum (2) is equipped with gear devices (11,12,-13) connected to and cooperating with the external drum (1) in such a way that the internal drum (2) rotates with a larger speed than the external drum (1) .

2. Device according to claim 1,
c h a r a c t e r i z e d i n that the ribs (4) of the external drum (1) are parallel with the rotational axis (8) of the drums (1,2) .

3. Device according to claim 1 or 2 ,
c h a r a c t e r i z e d i n that the ribs (9) of the internal drum (2) lie at an angle, e.g. within the interval 0-60°, preferably within the interval 0-45°, more preferred 0-30°, to the rotational axis (8) of the drums (1,2) .

4. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the cross section of the ribs (4) of the external drum (1) and/or the ribs (9) of the internal drum (2) have a rounded, e.g. an oblong or round, cross section.

5. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the gear devices (11,12,13) are formed of an unequal number frictional wheels and/or sprockets.

6. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the rotational speed of the internal drum (2) is 0,01-2 times larger than the rotational speed of the external drum (1) .

7. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the distance between adjacent ribs (4,9) in each of the drums (1,2) independently from each other, lie in the interval 0,5-20 mm, preferably 1-5 mm, more preferred 1-3 mm.

8. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the device is designed as a hand tool with a hoop and a handle (14) for leading the device.

9. Device according to any of the preceding claims, c h a r a c t e r i z e d i n that the internal drum (2) is equipped with a spring, e.g. a spiral spring, returning the drum (2) to its original position when the load on the external drum (1) is removed.

10. Device according to any of the preceeding claims, c h a r a c t e r i z e d i n that the rotational axis of the internal drum 2 is displaced with respect to the rotational axis of the external drum 1, preferably with a closest distance between the drums in the interval 0, 01 - 5,0 mm.
