Description

[Detailed description of the invention] (Field of the invention) This invention relates to a fish evisceration device, in particular,
This invention relates to a visceral removal device capable of removing mefun from a fish body subjected to abdominal surgery.

(Description of Prior Art) A conventional fish processing device including a fish viscera removal mechanism will be described with reference to FIGS. 1 to 3. FIG. Fig. 1 is a side view of a conventional fish processing device with the conveyor on the front side omitted, and Fig.
FIG.

A pair of left and right belt conveyors 1a and 1b are driven by a drive pulley 2 and run in the direction of arrow A in FIG. On the path of the fish 3 held between the belt conveyors 1a and 1b, there are, for example, a rotating knife 4 for laparotomy, a guide rail 5, a gutting pulley (pulley for removing internal organs) 6, a fillet knife 7, a discharge chute 8, etc. They are arranged sequentially from the beginning to the end. A pair of left and right guide rollers 11 provided on both sides of the gutting pulley 6
a, 11b are cylindrical as shown in FIG. 2, and are supported by vertical shafts 12a, 12b, respectively. Therefore, the clamping surfaces of the pair of belt conveyors 1a, 1b are kept parallel, and the fish body 3 is held on both sides. It is designed so that it can be held between the two sides. Also at the starting end of the belt conveyors 1a, 1b (fish introduction section 10), the clamping surfaces of the belt conveyors 1a, 1b are kept parallel by the tail pulley 9, so that the fish 3 can be clamped from both sides. Similarly, the guide rollers 13 and 14 located on both sides of the laparotomy rotary knife 4 and the fillet knife 7, respectively, also have guide rollers 11a and 11a.
Similarly to b, it has a cylindrical shape and is supported by a vertical shaft, and a pair of belt conveyors 1a and 1b are kept parallel to each other. As shown in FIG. 2, two gutting pulleys 6 are supported concentrically on a horizontal rotation shaft 15, and guide rails 5 are arranged on both sides of the pulleys.

Fish bodies are processed by this device as follows. That is, when the fish body 3 whose head has been cut and removed is introduced into the fish body introducing section 10 with the abdomen facing downward, the fish body 3 is transferred to both belt conveyors 1.
The abdomen of the fish body 3 is first cut horizontally by a rotary knife 4 rotating around a vertical axis, and an abdominal operation is performed. Next, fish body 3 subjected to abdominal surgery
is transferred to the gutting pulley 6 so as to straddle the guide rail 5, as shown in FIG. 2, and the internal organs inside the abdominal cavity 16 are scraped and removed by the gutting pulley 6, which rotates in the direction of arrow B in FIG. . The fish body 3 whose internal organs have been removed in this way is
Fillet knife 7 rotating in the direction of arrow C in Fig. 1
After being subjected to processing such as opening and cutting into three pieces, the fish is discharged by the fish body discharge section 8 in the direction of arrow D in FIG. 1.

However, according to this device, in the process of removing internal organs, the gutting pulley 6 ruptures the mefun (bag containing coagulated blood) 17 located in the upper part of the abdominal cavity 16, as shown in FIG. Although the mefun 17 can be removed by scraping, the guide rails 5 are located on both sides of the gutting pulley 6, and the gutting pulley 6 cannot be brought into contact with both sides of the abdominal cavity 16. However, there was a problem in that internal organs could not be removed reliably.

On the other hand, as shown in FIG. 3, there is another conventional example in which a guide rail 5' is arranged between two gutting pulleys 6'. ' is the abdominal cavity 16
Although the internal organs can be removed reliably by contacting both sides of the mefun, the mefun 17 cannot be removed because it is located on the guide rail 5' and the gutting pulley 6' cannot be brought into contact with the mefun 17. This problem is opposite to that of the conventional example described above. If a pastry product such as kamaboko is produced from a fish body with Mefun 17 still attached, the color of the product will darken, the taste will deteriorate, and the rate of decomposition will increase, resulting in a significant loss of product value.

(Purpose of the invention) The purpose of the invention is to provide a fish evisceration device that can reliably remove both viscera and mefun.

(Description of Embodiments) In summary, the device for removing internal organs from a fish body according to this invention includes a guide rail divided in the middle, a gutting pulley that rotates in the divided area, and a cross-sectional width of the gutting pulley. The outer periphery of the pulley is adapted to correspond to the abdominal cavity width of the fish to be processed, so that the outer periphery of the pulley comes into contact with the mefune in the abdominal cavity.

An embodiment of this invention will be described with reference to FIGS. 4 to 7. That is, in this embodiment, a guide rail 18 and a gutting pulley 19 shown in FIG. 4 are used in place of the guide rail 5 and gutting pulley 6 shown in FIG. 1.

The guide rail 18 is divided into two in the longitudinal direction in the middle, and a gutting pulley 19 is installed in the divided area.
Interpose. FIG. 5 shows a perspective view of the gutting pulley 19, and FIG. 6 shows a sectional view thereof. This gutting pulley 19 is set so that its cross-sectional width is slightly smaller than the abdominal cavity width of the fish to be processed (7th
(see figure), and taper-cut the corners on both sides of the pulley outer peripheral surface to form a tapered surface 20,
A large number of grooves 21 extending in a direction perpendicular to the circumferential direction of the pulley are provided on the tapered surface 20 over the entire circumference.
In addition, on both sides of the gutting pulley 19, there are many cleaning water inlets 22 (the diameter of which is, for example, 4 mm).
, and on the other hand, a large number of cleaning water outlets 24 (with a diameter of, for example, 4 mm) are provided on the outer peripheral surface 23 of the pulley.
Inside the gutting pulley 19, there is a water passage 25 that communicates the cleaning water inlet 22 and the cleaning water outlet 24.
will be established. A shaft insertion hole 26 is provided in the center of the gutting pulley 19, and by passing a horizontal drive shaft 27 through the shaft insertion hole 26 and holding it from both sides with clamping tools 28, the gutting pulley 19 is rotationally driven by the horizontal drive shaft 27. (The rotation speed is, for example, 1000r.pm). Other configurations are
Since this is the same as the conventional example described above, the same parts are given the same reference numerals and the explanation thereof will be omitted.

The process of removing internal organs using this device is carried out by rotating the gutting pulley 19 in the direction of arrow E in FIG.
This is done by spraying 0. In this way, the outer periphery of the gutting pulley 19 can rotate and enter into the abdominal cavity 16 of the fish 3 that is being conveyed along the guide rail 18 (FIG. 4) while being held between the conveyor belts 1a and 1b. become. In this case, since the guide rail 18 is divided and the gutting pulley 19 is interposed in the divided region, the outer circumferential portion of the gutting pulley 19 can be reliably brought into contact with the mefun 17, and the gutting pulley 19 Since the tapered surface 20 is formed on the outer circumferential portion of the pulley 19, an edge 31 is formed at the boundary between the tapered surface 20 and the pulley outer circumferential surface 23 (FIG. 6), and this edge 31 and the groove formed on the tapered surface 20 21, the mefun 17 can be reliably broken and scraped off. Further, since the cross-sectional width of the gutting pulley 19 corresponds to the width of the abdominal cavity of the fish body 3, the gutting pulley 19 can come into contact with both sides of the abdominal cavity 16 to reliably scrape out internal organs. Moreover, the cleaning water 30 sprayed from the hose 29 toward the lower side of the gutting pulley 19 enters the water passage 25 from the cleaning water inlet 22.
Since the cleaning water is blown out from the cleaning water outlet 24 into the abdominal cavity 16 of the fish body 3 by the centrifugal force caused by the rotation of the gutting pulley 19, the internal organs and mefun scraped by the gutting pulley 19 are cleanly washed downward with the cleaning water. I can do it. In this way, it becomes possible to reliably remove both the internal organs and the mefun.

(Effects of the invention) As explained above, according to the fish viscera removal device according to the invention, it is possible to reliably remove both the viscera and mefun of the fish body.
