(54) DEVICE FOR REMOVING THE INTERNALITY OF FISH ¢ 7) Use: in the processing of spindle-shaped fish of various sizes without preliminary sorting by size to improve the quality of removal of entrails by ensuring uniform pressure on the fish’s abdomen with the help of a movable screw 5 having flexible rib edges made of rubber. The screw is installed with the ability to move vertically and change the angle of inclination. A conical roller 3 is mounted in front of the circular knife 4 to displace the viscera before cutting off the head. 1 ill.

The invention relates to the processing of fish, and more particularly to cutting spindle-shaped fish and removing entrails from it.

A device is known for removing internal organs and selecting caviar T0UO-660 (company TAYO GyoGyo Japan, Tokyo, 1988), moreover, the removal of internal organs and the selection of caviar is carried out using a roller.

The disadvantage of this device is 10 frequent jamming of the roller due to the sticking of scales on it, as well as the inability to work with fish of different sizes.

A device is also known for removing entrails and selecting caviar, including a chain conveyor, circular knives, an extrusion extrusion device made in the form of a turntable with rubber fingers.

A disadvantage of the known device is the · 20 incomplete removal of the viscera, since the fingers of the turntable pass along the fish once, as well as the uneven pressure of the fingers on the fish.

The aim of the invention is to improve the quality of fish processing by ensuring uniform pressure in the process of removing entrails.

This goal is achieved by the fact that in the device containing the conveyor with 30 cassettes, circular knives, means are introduced for uniformly extruding the viscera of the fish, made in the form of a screw having flexible ribs, for example rubber, and the screw is installed 35 at an angle to the direction of movement of the conveyor with cassettes, parallel to the plane of the latter, with the possibility of moving the screw in the vertical and horizontal planes, which is ensured by 40 installing the screw in a movable frame with the ability to move vertically cial and horizontal planes.

The rotation of the auger is transmitted, for example, from a conveyor drive through a cardan shaft.

The drawing shows a device, General view.

The proposed device includes a conveyor with cassettes 1, where the fish 50 is manually fed from the conveyor belt 2, a movable cone roller 3, designed to move the tongue in front of the head to prevent damage to the latter, a disc knife 55, designed to separate the head, a movable screw 5, mounted at an angle to the longitudinal axis of the cassette conveyor with the ability to move in a vertical plane and change the angle of inclination to the longitudinal axis of the conveyor, which is provided by installing a screw Emer, a movable frame having the possibility to move in the 5 vertical and horizontal planes and intended for removing the viscera from fish.

The device operates as follows.

The fish from the conveyor belt 2 is manually placed in the cassettes of the conveyor 1 so that the back of the fish is located in the cassette below, and the head • is located in this way. so that the line of separation of the head runs directly behind the gill covers. Further, the fish, moving in the cassettes of the conveyor 1, falls under the pinch roller 3, which ensures the displacement of the tongue before separation of the head, which eliminates damage to the latter. Then the fish falls under the circular knife 4, with the help of which the head is separated.

To separate caviar roasts and internal fish, the fish is fed under a movable auger 5, mounted at an angle to the longitudinal axis of the cassette conveyor 1. having the ability to move in vertical and horizontal planes. To ensure the processing of fish of various sizes and to avoid damage, the turns of the ribs of the movable screw are made flexible, for example, from rubber. Fish falling under the movable screw 35 auger 5 is freed from the caviar and insides with its help, and the quality of removal does not depend on the size of the fish, since several flexible ribs 40 of the movable screw 5 pass along the fish during the removal process. removal depends on the rigidity of the flexible ribs of the screw.

The proposed device allows for high-quality removal of 45 entrails and fossae regardless of the size of the fish; operator qualifications, as well as increase the speed of its processing.
