Abstract

The invention relates to the fishing industry and can be used in devices for cutting fish (beheading, cutting into pieces). The aim of the invention is to improve the quality of cutting by uniformly washing the knife during processing, removing adhered parts of the product and reducing the cutting force. The device contains mounted on a horizontal shaft 2 disk knife 1. The shaft 2 is made hollow. The knife 1 on both sides covers a separating washer 4, in which an annular cavity 5 and radial through channels 6 are provided, communicated with the cavity of the shaft. Water enters through the hollow shaft into the cavity 5 and channels 6 and completely wets the cutting surface of the knife, preventing protein formations from sticking to it. 5 il.

Description

FIELD OF THE INVENTION The invention relates to the fishing industry, in particular to devices for cutting fish (beheading, filleting, cutting fish into pieces).

The purpose of the invention is to improve the quality of the cutting by uniformly washing the knife during processing, removing adhered parts of the product and reducing the cutting force.

FIG. 1 schematically shows a device for cutting fish, a general view; in fig. 2 shows a section A-A in FIG. 1 in FIG. 3 - circular knife, general view; in fig. - node I in FIG. 3; in fig. 5 shows an embodiment of a knife (twin knives).

The device for cutting fish contains a disk knife 1 mounted on a shaft 2 placed in a roller support 3, and a water supply system (not shown). The device is also equipped with a detachable washer 4, which encloses the knife 1 on both sides and is fixed on the shaft 2. The washer A has an interconnected annular cavity 5 and through radial channels 6. The shaft 2 is made hollow to communicate the annular cavity 5 with these I . . .

Subject of the filing of the zods. The inner surfaces of the detachable washer k are made obliquely around the periphery in the direction of the disk knife 1. Under the knife 1 there is a transporting organ 7 with cassettes 8 for fish. A tray 9 for collecting and draining water is installed under the toe-porting body 7 and the knife 1, the casing 10 is above the knife 1. The separating washer 4 is fixed on the shaft 2 by means of a threaded nut 11.

The device works as follows.

The transporting body 7 moves the cassettes 8 from the fish picked up in them to the disk knife 1. The latter rotates on the shaft 2 and makes the cutting of the fish (decapitation or cutting into pieces).

At the same time, water is supplied from the system, which through shaft 2 enters washer k, fills cavity 5 and channels 6. This forms a hydraulic pressure ring, which is pressed by the action of centrifugal forces to the inlets of channels 6. As a result, the output slot channels 4 there is an additional uniformly directed to 0

the surface of the water knife, which excludes the possibility of the disruption of water droplets radially from the axis and parallel to the surface of the knife and the disruption of the film distribution of water over the knife surface. Therefore, when rotating the Disk no 1 under the action of centrifugal forces and the pressure ring, the water is evenly distributed over the entire cutting edge of the knife and forms a uniform water film.

By making the inner surfaces of the washer k skewed along the periphery towards the knife 1, the water velocity at the outlet of the cavity 5 and the channels 6 of the washer is increased due to ejection. As a result, water is directed along the entire perimeter of the washer k on the surface, ..: of the disk knife 1 on both sides of the axis of rotation.

As a result of such uniform washing of the knife during processing of the fish, the adhered parts of the product are constantly removed, which helps to reduce the effort to cut the carcass of the fish, to achieve an even cut and to prevent deformation of the carcass or fish pieces, i. improve the quality of cutting fish.

In addition, water at the entrance of the knife 1 in the fish carcass completely wets the cut area. All this also contributes to reducing the effort of the cut, obtaining an even cut of the carcass of the fish without warping it. The casing 10 prevents splashing of water when cutting fish. The water from the knife 1 is collected in tray 9 and discharged into the system. For filleting fish (cutting into longitudinal pieces) a device with a double disc knife (Fig. 5) is used, which operates in the same way,
