Description

[Detailed explanation of the idea] This proposal concerns a fish descaling device.

In the conventional descaling device, a water pipe provided with a large number of injection holes for pressurized water is fixed, and the fish body is conveyed in a fixed direction by a belt facing the injection holes, and during the conveyance, the pressure water from the injection holes is It's as if it's taking off scales.

By the way, in the conventional device, the pressure water from the injection hole 1 is sprayed in a fan shape as shown in FIG. Therefore, when the fish is descaled, pressure water greater than that required for descaling acts on the part of the fish body facing the part 2, and as a result, as shown in Figure 6, the part where the skin has been removed along with the scales is coated in the vertical direction. Linear stripes 3 remain on the fish, and these stripes 3 reduce the commercial value of high-quality fish, such as sea bream, whose skin containing special pigments is important.

In order to eliminate this drawback, it is possible to lower the pressure of the pressurized water or reduce the amount of pressurized water sprayed, but when doing so, it is not possible to remove the scales.

Furthermore, the conventional device cannot uniformly spray pressurized water over the entire surface of the fish body.

To explain in more detail, as mentioned above, the position of the injection hole 1 is constant, and the side surface of the fish body conveyed in a certain direction by the belt is arc-shaped, so the pressure changes depending on the positional relationship between the injection hole 1 and the fish body. The problem is that the fish body has blind spots in relation to the water, and the fish body does not receive the pressure water evenly.

In order to reduce the number of blind spots, it is possible to increase the number of injection holes 1, but doing so increases the size of the entire device and requires extra power and water. .

This idea was devised in view of this point, and the idea is that it is possible to uniformly spray the pressure water necessary and sufficient for descaling over the entire surface of the fish body.
Although the scales are removed, the epidermis is not damaged, so stripes do not occur as in the conventional device, and the number of injection holes is reduced to make the device smaller, saving water and labor. In order to exhibit the above-mentioned characteristics, the gist of the present invention is that a water pipe provided with a large number of injection holes for pressurized water is swingably provided on a fixed support.

Next, one embodiment of the present descaling device will be described based on the drawings.

Reference numeral 4 denotes a water pipe made of a hollow body with one end closed, and a pipe 5 made of a flexible material such as a rubber pipe is connected to the other end of the water pipe 4. A large number of injection holes 1 are provided at intervals in the axial direction of the tube 4, near the top and near the bottom.

(See FIG. 1) (Hereinafter, this type of device will be abbreviated as a descaling device A.

) Also, as shown in FIG. 2, a large number of injection holes 1 may be provided on a straight line approximately in the center of the water pipe 4 in the axial direction.

(Hereinafter, this type of device will be abbreviated as descaling device B.

) Also, as shown in FIG. 3, a large number of injection holes 1 may be provided in a straight line near the upper part of the water pipe 4 in the axial direction, or only near the lower part (not shown).

(Hereinafter, this type of device will be abbreviated as a descaling device C.

) Also, although not shown, a large number of injection holes may be provided in a straight line over substantially the entire length of the water pipe 4.

(Hereinafter, this type of device will be abbreviated as a descaling device.

) Thus, the water pipe 4 constructed as described above is pivotally attached 8 to a support 7 fixed to a suitable fixing member 6, while a connecting plate 9 is connected and fixed to the lower part of the water pipe 4. , is pivotably mounted 11 to a shaft 10 fixed to the lower part of the fixed member 6 and which moves left and right with a constant stroke, and is configured to be swingable about the eight pivot points by the left and right movement of the shaft 10. It is.

The descaling device of the present invention is constructed as described above.

Since the proposed descaling device is constructed as described above, the first
As shown in the figure, when the water pipe 4 is swung around the eight pivot points via the shaft 10 as shown by the one-dot chain line and the two-dot chain line, the part 2 on the extension line of the injection hole 1 is moved by the fish body being conveyed by the belt. Since the pressure water moves vertically along the sides, and as a result, the pressure water collides with the fish body on average and descales it, so the pressure and amount of the pressure water should be set to a pressure and amount suitable for descaling. This has the remarkable effect of preventing the occurrence of stripes 3 caused by damage to the epidermis, unlike the conventional device.

Further, in the present device, the position of the injection hole 1 moves in an arc shape through the water distribution pipe 4 as described above, so the fan-shaped pattern of pressurized water from the injection hole 1 moves, and as a result, the spray range expands. Unlike conventional devices, there is no blind spot on the fish body, and since the spray range is wide, it is possible to reduce the number of injection holes 1, making the device compact and labor-saving, as well as saving water, which is a remarkable effect. be.

Next, an embodiment of a descaling machine employing the descaling apparatus of the present invention will be described based on FIG. 4.

Reference numeral 12 denotes a base plate, and rotatable endless belts 13 and 14 are provided on the base plate 12 with a distance d between them so that the conveying surfaces of the belts 4 are flush with each other.

Similarly, on the base plate 12, an endless belt 1 is rotatable facing the endless belts 13 and 14 at a distance d1, and is separated by a distance d2, with the conveying surface of the belt being flush.
5.16.

Therefore, the endless belt 13, 14 and the endless belt 15
．． When the belts 16 are provided facing each other, the distances d and d2 are set so that they do not face each other, and each of the belts 13, 14, 15 and 16 is arranged so that the conveying surface thereof is perpendicular, and The width of the belt is narrow enough to grip only the vicinity of the vertical (height) center of the fish to be transported.

17, 1B is the descaling device A fixed on the base plate 12 at a position within the endless belt 13.15;
In this case, the belts 13 and 15 are fixed in the vertical direction so as to face the water pipe 4 near the axial center thereof.

In other words, the plurality of injection holes 1 are connected to the endless belt 13.
．． 15 so as to face each other above and below.

Reference numerals 19 and 20 indicate the descaling device B provided at the interval portion d and the portion 62, and the device B has a large number of injection holes 1 located at approximately the same height as the endless bell (13.15). Naruyo<
Moreover, it is fixed on the base plate 12 in the vertical direction opposite to the endless belts 15 and 14.

Further, 21 is the upper part of the above-mentioned interval d1, and the injection hole 1 is directed downward in the horizontal direction, and 22 is next to the above-mentioned 21 and is also at the interval d1.
The descaling device C is provided on the base plate 12 in the lateral force direction 1 with the injection hole 1 facing upward at the lower part of the part.

It should be noted that the same effect can be obtained even if the above-mentioned descaling device R is used in place of the descaling devices A, B, and C.

Furthermore, due to the size of the fish, the endless belt 13.1
5 and 14. When 16 does not face approximately the vertical center of the fish body, adjust the position of the base plate 12 to remove the endless bell) 13.
, 15, 14, and 16 are preferably arranged so as to face substantially the center of the fish body in the height direction, so that the fish body can be transported reliably.

Furthermore, in the conveying direction of the endless belt 13.15, the endless belt 13.15 is energized at the front and back positions of the descaling device A in the direction of narrowing the interval d1 between the endless belts 13.15. A pair of rollers 23 and 24 are provided, and the descaling device A
It is preferable to prevent the fish body from shaking due to the jet of pressurized water.

Furthermore, although not shown in the drawings, it is preferable to provide a roller for the same purpose as above in the vicinity of the descaling device C.

In the descaling machine configured as described above, a fish body is inserted into the interval d1, held between the endless belts 13 and 15 provided facing each other, and conveyed in the direction of the arrow.
8 In other words, the scales are removed using pressure water from the descaling device A.

However, since the fish body is held between the narrow endless bells N3 and 15 as described above, the part covered by the bells 13 and 15 reaches the interval d in the state of free scales and is descaled. Pressure water from device B descales the unscaled portion, and then the spacing 62
The unscaled part on the opposite side is also descaled by descaling device B.

That is, the side surfaces of the fish body are mainly descaled before reaching the descaling device 21, and in addition, as described above, there are many injection holes 1.
However, since the pressure water moves in an arc along the height direction of the fish and is uniformly ejected onto the sides of the fish, stripes 3 due to damage to the epidermis do not occur as in the conventional device, and there is no damage to the skin in blind spots as in the conventional device. This has the remarkable effect of preventing the occurrence of unscaled areas.

Next, in the descaling device 21, the back of the fish body, in other words, the area around the head and dorsal fins that are difficult to descale, is descaled, and then in the descaling device 22, the abdomen of the fish body, in other words, the pectoral fins, which are difficult to descale, are descaled. The surrounding area is stripped of its scales.

That is, the combination of descaling devices A, B, and C sequentially descales the sides, back, and abdomen of the fish body, so that the stripes 3 do not occur even though the fish can be completely descaled.

Furthermore, an endless belt 13.1 is attached to the water pipe 4 of the descaling device A.
No injection hole 1 is provided in the part facing 5, and the descaling device B
In the water distribution pipe 4, the injection hole 1 is provided only near the axial center of the water distribution pipe 4, and in the descaling device C, the number of injection holes 1 is reduced to make effective use of pressure water. As a result, the purpose of energy saving and water saving can be achieved at the same time, and the device can be made smaller, which is a remarkable effect.

Since the descaling device of the present invention is constructed as described above, as is clear from the above explanation, stripes due to damage to the epidermis do not occur during descaling, and the number of injection holes is reduced (by which the device is miniaturized and water is saved). At the same time, it has the remarkable effect of saving labor.
