<p>A process and an apparatus for mechanical opening of the bloodstream of flat-fish, the application of which has the aim of the bleeding of the fish. The apparatus proposed for this is equipped with a rotatingly driven knife sleeve, which is sharpened at its end side and which is constructed to be lowerable onto the flat-fish aligned to be lying flat under this, and at its circumference carries tearing elements extending radially in the proximity of the cutting edge. The tool, penetrating into the abdominal cavity during lowering while separating circular area portions out of the oppositely disposed abdominal walls, tears the bloodstream disposed at the underside of the spinal column open by means of the radial tearing elements. Through a radially deviatable arrangement of the latter, there results an adaptation of the tool to the geometric conditions of the abdominal cavity as well as an enlarged radius of action through the ratation in consequence of centrifugal forces, which effects the tearing loose and comminution of the intestines. The feeding of rinsing liquid through the center of the tool into the abdominal cavity makes the flushing-out of belly contents possible.</p> |
