Abstract
The invention relates to a process and an apparatus for heading and eviscerating fish in which the head and the entrails are integrally removed from the body of the fish. According to the invention, only the neck of the fish is cut, after which the head is turned down through approximately 90.degree. in relation to the axis of the body and, finally, the head undergoes a relative displacement along the body of the fish towards the rear thereof. As a result, the fish is completely eviscerated. The apparatus for carrying out the process essentially comprises a cutter for cutting the neck, a guide for turning down the body of the fish and two holders, one for the head and the other for the body of the fish, which receive different movements responsible for the above-mentioned displacement.
Claims9
An apparatus for heading and eviscerating fish in which the entrails of the fish remain attached to its head and are withdrawn from the body of the fish during removal of the head, which comprises:
- entraining means (1,2) for holding the head of the fish,
- means (5, 6) for holding the body of the fish during the heading operation and being provided with a curved and angled guide (6) of which one end forms a passage (7) with the said entraining means (1, 2) whilst its other end is substantially perpendicular thereto,
- means (8) for cutting the neck of the fish, the fish being treated neck first lying on one of its sides, said cutting means (8) being disposed in front of the passage (7) formed by the guide (6) and the entraining means (1, 2), said guide (6) cooperating with the entraining means (1, 2) for effecting turning of the body of the fish down through an angle of substantially 90.degree. once the neck has been cut, so that, on turning, the abdomen of the fish is facing the head entraining means (1, 2), and
- means (11, 12) for gripping the body of the fish arranged parallel to the entraining means (1, 2) and imparting a faster advance movement to the body of the fish than to its head to thereby produce a relative displacement of the head along the body of the fish toward the rear thereof.
