, 54) DEVICE FOR FILING FISH

The invention relates to the production of H.i fish fillets, in particular non-divided fish with 6m catfish, such as cod, parc, pollock. A device for filleting fish containing a transporting organ with holders for fish, paired knives for cutting, fish along the ridge on the side of the snake and abdomen, and paired tools for separating the flj fillet are known. The known device does not provide a sufficiently high performance. the complete removal of the thin bones requires the removal of the intestines from the fish, while the meat from the abdominal part is usually crushed. The purpose of the invention is to improve the performance of the device. The goal is achieved by the fact that, in the proposed device for filleting fish, the tools for separating and fillet are made in the form of diverging vanes with slots for the passage of ribs and thin bones. In addition, each blade is formed in two parts with cutting edges installed to adjust the gap between them. At the same time, the device is equipped with means for heat treatment of fish in places of attachment of thin bones to the skin, made in the form of steam jet nozzles. FIG. 1 shows schematically a device for filleting fish, a general perspective view; in fig. 2 - fishery cavity on the holder, end view; in fig. 3 shows a variant of the arrangement of the blades, axonometrics. The device (Fig. I) contains a transsorbing body 1 with movable holders 2 for fish 3, paired knives 4 and 5 for cutting fish along the ridge, respectively, from the back and stitcher, paired tools for separating fillets, means for heat treating fish in places attaching thin bones to the skin and a paired cleansing knife 6 DON'T remove the bone from the fish between the thin bones and ribs. The tools for separating the fillet are made in the form of diverging vanes 7 with slots 8 for the passage of ribs 9 and thin bones 10. For a small fish (cod), the width of the slot can be 5 mm. Means for heat treatment of fish in places of thin bones of Crepenche 10 K. The skin is made in the form of steam jet nozzles 11. During filleting, fish 3 is placed on a movable holder 2 head forward in the direction of arrow A. A line of forward protrusions 12 on the upper surface of the holder hook is opposite the vertical paranoids provide a solid mount, and the swim bladder of the fish is positioned on a holder within such protrusions (Fig. 2), while the shape of the holder 2 ensures equal penetration of the abdomen; y, o polo st. .

The fish is firmly attached to the holder 2 and continuously fed to successive processing steps. The holder then moves at a constant speed, for example, 0.5 m / s (or 38 holders per minute). The fish is sent for subsequent operations using a pair of spring-loaded guides 13. First, paired knives 4 make the upper initial incision along the ridge P of each side of the back of the fish, with an atom, the distance between the incisions is approximately 6 mm near the spine I. Then the paired the knives 5 make cuts below the fish or from the side of the abdominal bones (Fig. 2), the knives rotate in the opposite direction relative to the flow direction to ensure the fish is drawn and accurate notching without disturbing its structure. Knives have a diameter of 200 mm and rotate at a speed of 850 rpm.

The fish is then fed to the blades 7 and the fillet cutting stage, with a pair of diverging blades penetrating the cuts of the fish formed by the knives 4 and 5. The leading edge of each blade is initially located in the plane B of the blades 4 (f. 2), then The vanes gradually disintegrate, drawing the fillets, and finding them from the carrier 2 moving line. Such fillet parts are assembled for further processing.

Next, the exit fish is fed for cleaning, while the cleaning knives 6 remove the V-shaped pieces from the fish between the thin bones and the ribs.

These small pieces of meat are then separated from the various bones and ribs by grinding. The joint between the flesh bones and the skin of the fish in the filleting process is separated by steam jet nozzles II, while this provides better consistency due to the absence of thin bones.

In another embodiment (FIG. 3), each blade is formed by two upper and lower parts 15 and 6. The upper part 5 of the blade has a surface 17 and is fixed, and the lower / part 16 is hinged on the axis 18 opposite the spring (shown) and has cutting edges 19 on each side. Between the upper to lower parts 15 and 16 of the blade there is a slot 20, the width of which varies during the process from the input end (for example, from axis 18), preferably 5-7.5 mm.

In the narrow place of the slot 20, there is a spring (not shown) and when the bones hit, the latter put pressure on the slot, opening it to the spine, and such bones are let through without damage.
