During this time, the fish 80 is pressed down by the presser roller 42 and is in close contact with the film peeling blade 33. When the fish body 80 is large, the membrane peeling blade 33 compresses the spring 36 so that the tip side is slightly lowered and pivoted about the pivot 35 so as not to be excessively pressed against the membrane peeling blade 33. It has become. Accordingly, it is possible to eliminate the meat scraping phenomenon in the vicinity of the tail portion of the fish body 80 that occurs when the film peeling blade 33 is fixed.

  As shown in FIG. 29 (e), the fish egg 84 and the internal organs 85 taken out from the fish body 80 together with the body cavity membrane 86 are dropped and recovered by separating the body cavity membrane 86 from the fish meat 81. In addition, the fish body 80 from which the fish egg 84 and the internal organs 85 are separated moves on the film peeling blade 33 while being prevented from being lifted by the second pressing guide 34, and scrapes the blood pool 83 by the scraper 50 along the way. Taken. In response to a change in the scraping resistance of the scraper 50 due to a change in the size of the fish body 80, the spring 54 is extended and the scraper 50 sinks into the membrane peeling blade 33, so that the necessary blood pool 83 is scraped off as necessary. Moreover, damage to the fish body 80 can be avoided.

  As shown in FIG. 16, the fish 80 whose blood pool 83 has been scraped off by the scraper 50 moves on the membrane peeling blade 33 to the downstream side, and the residual material in the body cavity is removed by the rotating brush 47. Washing water is constantly sprayed from the nozzle 57 to the brush 47 to wash away foreign matter.

  The fish 80 that has passed the brush 47 is placed on the washing nozzle block 48 and the body cavity is washed with the washing water sprayed from the nozzle 58.

  Thus, the film peeling blade 33 is adjusted to an optimum position corresponding to the size of the fish body, and the fish egg 84 and the internal organs 85 can be reliably removed without damaging the fish meat 81.

Both fish eggs can be separated from the fish body.

  Further, the cross-sectional shape of the arm 109 is circular in this embodiment, but may be other shapes such as an ellipse, a triangle, and a quadrangle.

  Below the fixed frame 102, a lower opening 114 is provided, and a chute 113 for receiving a fish egg separated from the fish body is disposed. Below the lower opening 114 of the chute 113, a fish egg is stored. A container (not shown) is installed.

  Next, the operation of the present embodiment having the above-described configuration will be described.

  In the fish egg and visceral take-out device of this embodiment, the fish body (not shown) whose head is cut is the front part of the fish body (not shown) which continues to the head along the belly receiving plate 1 in the same manner as the device of Patent Document 1 described above. So as to be sandwiched from both sides by a pair of conveyor belts 5, 5. Then, the insertion portion 12 of the slide guide 10 is inserted into the abdomen of the fish body, and the frame 7 is slightly rotated counterclockwise. The rotation angle of the frame 7 changes according to the shape of the fish body, and the position of the cutting blade 9 is automatically adjusted to the minimum depth of cut to always cut the abdomen of the fish body along its lower edge. The meat of the fish belly is introduced between the insertion part 12 and the cutting blade 9, and only the meat of the stomach is cut. For this reason, the fish eggs in the body are not damaged.

  When the insertion portion 12 of the slide guide 10 is inserted to the vicinity of the anus of the fish body, the tip of the insertion portion 12 is pushed by the fish meat, and the slide guide 10 moves downstream. The cutting blade 9 is greatly exposed by the movement of the slide guide 10 and accurately cuts up to the anus of the fish body. During this time, the first presser guide 30 presses the upper surface of the fish and prevents the fish from being lifted.

  Next, the fish that has been cut open through the abdomen through the slide guide 10 is seated so that the spine is placed on the horizontal edge 104 from the inclined edge 103 of the first bone placement plate 101. Then, the fish body expands its abdomen by the bent portions 108a and 108b of the upstream guide members 106 in the transport direction of the fish attached to both side surfaces 105 and 105 of the first bone placement plate 101. It will be. Then, each fish egg hangs down so as to be partially exposed to the outside by its own weight from between the inside of the spread belly and the bent portions 108a and 108b of the guide member 106.

  In this state, when the fish body faces the arm 109 located on the downstream side of each of the upstream guide members 106, the intermediate portion 111 of the arm 109 enters the body cavity of the fish body, The base end portion of the covering body cavity membrane is caught by the intermediate portion 111 of the arm 109, and the body cavity membrane is cut at the intermediate portion 111 of the arm 109 as the fish moves, and the fish egg is separated from the fish body and falls. It will be. At this time, the liver is also separated from the fish body and dropped together with the fish eggs on the left side.

  The egg and liver that have fallen in this manner are collected from a lower opening 114 of the chute 113 into a container (not shown).

  If the fish eggs are not removed by the upstream guide member 106 and the arm 109, the fish eggs will be removed again by the downstream guide member 106 and the arm 109, so that the fish egg is reliably removed. can do.

  The fish body from which the fish egg and liver have been separated is then placed on the second bone placement plate 32 and guided to the membrane peeling blade 33. Then, the membrane peeling blade 33 is inserted into the fish body, and the blood pool is cut while peeling the body cavity membrane. During this time, the fish is pressed down by the presser roller 42 and is in close contact with the film peeling blade 33.

  And the internal organs including the intestines taken out from the fish body together with the body cavity membrane are dropped and recovered by separating the body cavity membrane from the fish meat. Further, the fish body from which the internal organs are separated is moved on the film peeling blade 33 while being prevented from being lifted by the second pressing guide 34, and the blood pool is scraped off by the scraper 50 on the way.

  Next, the fish body whose blood pool has been scraped off by the scraper 50 moves on the membrane peeling blade 33 to the downstream side, and the residual material in the body cavity is removed by the rotating brush 47. Washing water is constantly sprayed from the nozzle 57 to the brush 47 to wash away foreign matter.

  The fish passing through the brush 47 is placed on the washing nozzle block 48, and the body cavity is washed with washing water sprayed from the nozzle.

  As described above, according to the fish egg and viscera extraction device of the present embodiment, the fish egg is separated and removed from the viscera including the intestine to which many germs adhere, so that the fish egg is brought into contact with the intestine. The freshness and taste of fish eggs can be maintained well.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
