DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is a perspective view showing an overall schematic configuration of a washing / draining line 100 equipped with a fish washing apparatus 1 according to this embodiment among fish treatment lines provided in a fish processing facility to which the present invention is applied. .
[0013]
In FIG. 1, the washing / draining line 100 is disposed on the fish body washing apparatus 1 including the first washing line 1A and the second washing line 1B arranged on the downstream side thereof, and further on the downstream side of the second washing line 1B. It consists of a draining line 2. The first cleaning line 1A mainly cleans the fish body F first, and the second cleaning line 1B further cleans the fish body F cleaned in the first cleaning line 1A secondarily and cleanly. To sterilize.
[0014]
In common with the first cleaning line 1A and the second cleaning line 1B, a cleaning tube 3 for cleaning the fish F from the inner peripheral side is provided. Although not shown in FIG. 1, cleaning water is appropriately sprayed from the outer peripheral side of the conventionally known fish body F in addition to the cleaning pipe 3 in at least one of the first cleaning line 1A and the second cleaning line 1B. Needless to say, an external cleaning means (external nozzle or the like) for flowing down may be provided. Further, the scale may be removed by the external cleaning means (descale may be performed in advance before the introduction into the first cleaning line 1A).
[0015]
FIG. 2 is a perspective view showing the entire structure of the cleaning tube 3.
In FIG. 2, for example, brackets (holders) 4 are fixed to both ends of the cleaning tube 3 by welding or the like, and a long hole 5 in a substantially vertical direction is formed in the bracket 4. On the other hand, 6 is a substantially L-shaped attachment member for supporting and fixing the cleaning tube 3 to a fixed side member (such as a gantry) (not shown), a horizontal portion 6a constituting a substantially L-shaped bottom, and a substantially L-shape. It is comprised from the vertical part 6b which comprises a standing standing part.
[0016]
A through hole 7 is formed in the horizontal portion 6a. After the bolt 8a having penetrated the above-mentioned fixed side member is further passed through the through hole 7 from below, the nut 8b is fastened to fix the mounting member 6 Is fixed to the fixed side member. And the through-hole 9 is formed also in the vertical part 6b, and after making the bolt 10a which penetrated the long hole 5 of the above-mentioned bracket 4 penetrated the through-hole 9, fastening the nut (wing screw) 10b. Thus, the bracket 4 is attached to and supported by the attachment member 6, whereby the cleaning tube 3 is supported by the fixed side member. At this time, the position in the height direction of the washing tube 3 can be adjusted by loosening the nut 10b and adjusting the position where the bolt 10a passes through the long hole 5, and as a result, according to the size of the fish F to be washed. The relative distance between upper and lower conveyors 12U and 12L, which will be described later, can be freely adjusted.
[0017]
In addition, the cleaning tube 3 is composed of, for example, a SUS tube and has a substantially inverted L shape when viewed from above, as shown in FIG. 2, and a cleaning unit 3A linearly extending in the conveying direction of the fish F, The washing unit 3A is located on the downstream side in the transport direction, and includes a water guide unit 3B that is bent at a right angle from the transport direction to the left side. Although detailed description is omitted from the end portion of the water guide portion 3B, wash water for washing the fish is introduced from a water guide pipe (not shown) (see the arrow in FIG. 2).
[0018]
FIG. 3A is a top view showing a detailed main structure of the cleaning tube 3, and FIG. 3B is a side view as seen from the direction of arrow A in FIG.
In FIG. 2, FIG. 3 (a), and FIG. 3 (b), the cleaning section 3A is introduced on the left side in the conveying direction of the fish F (on the back side in FIG. 2). A water injection hole 11 for ejecting the cleaning water introduced from the portion 3B is provided. In detail, the water injection hole 11 is composed of, for example, three substantially circular first water injection holes 11A and two second water injection holes.
[0019]
The first water injection hole 11A is for injecting cleaning water to the spinal cord portion located in the upper center part (spine side) of the fish body F, and the injection hole 11A1 provided at the horizontal position in the left direction of the cleaning pipe 3; Three injection holes 11A2 provided with a slight shift downward from this and reverse injection holes 11A3 provided with a slight shift from the injection hole 11A1 are arranged in the conveying direction of the fish F in this order. By providing the injection holes 11A2 and 11A3 that are slightly deviated in addition to the injection holes 11A1, when the fish bodies F are somewhat uneven in size, or when inserted into the cleaning tube 3 and conveyed, the posture is rotated slightly. Even if it is off, it can respond freely, and it can surely inject washing water into the spinal cord. In particular, the spinal portion is spray-washed in a spot manner because the kidney is often attached to the abdominal spinal portion of the fish F even after the internal removal, and is usually the largest in removing and washing this portion. This is because it takes time and effort.
[0020]
The second injection hole 11B is for spotting the spinal cord portion with the first injection hole 11A and then injecting cleaning water to the periphery thereof, and mainly around the lower side from the horizontal position in the left direction of the cleaning tube 3. The injection holes 11B1 for injecting the cleaning water into the parts and the injection holes 11B2 for injecting the cleaning water mainly into the upper peripheral part are arranged in this order in the conveying direction of the fish F. As shown in FIG. 3B, these injection holes 11B1 and 11B2 have, for example, a substantially elongated shape (slit shape, elongated hole shape, etc.).
[0021]
Returning to FIG. 1, the first cleaning line 1A and the second cleaning line 1B are also provided with an upper conveyor 12U and a lower conveyor 12L above and below the cleaning tube 3, respectively. By these upper and lower conveyors 12U and 12L, the fish F inserted into the washing tube 3 is transported while being sandwiched from the upper and lower sides. The draining line 2 that does not have the washing tube 3 is also provided with upper and lower conveyors 13U and 13L having the same configuration for transporting the fish F from above and below.
[0022]
In the above configuration, the fish F is decapitated by a known method in advance and is removed from the built-in state so that the fish F is at the inlet portion on the upstream side (left side in FIG. 1) of the first cleaning line 1A. Is inserted into the washing tube 3 so as to be skewered in the direction of the spine in a lying position. FIG. 4A is a top view showing a state in which the fish F is inserted into the cleaning tube 3 at this time, and FIG. 4B is a side view seen from the B direction in FIG. 4A. .
[0023]
The fish F is inserted into the washing tube 3 and is held by the upper and lower conveyors 12U and 12L from above and below, and is conveyed in the first washing line 1A in the right direction in FIG. (See thick arrow in FIG. 1). During this conveyance, washing water is jetted from the water jet holes 11A and 11B provided in the washing tube 3, and the fish F is washed from the inner peripheral side centering on the spinal cord and its peripheral part (FIG. 4 ( a) See middle dashed arrow).
[0024]
When the fish F comes to the downstream end of the first washing line 1A while being washed as described above, the fish F is inserted into the washing tube 3 and is connected to the upper and lower conveyors 12U, 1U of the first washing line 1A. Transfer from the terminal end of 12L to the start end of the second cleaning line 1B, and again between the upper and lower conveyors 12U and 12L of the second cleaning line 1B in the same manner as the first cleaning line, The line 1B is conveyed rightward in FIG. 1 (see thick arrow in FIG. 1). Similarly, during the transportation, washing water is sprayed from the washing tube 3 and the fish F is washed from the inner periphery with the spinal cord and its peripheral part as the center.
[0025]
When the fish F reaches the downstream end of the second washing line 1B while being washed as described above, the fish F is guided by the release plate 14 provided at the end of the washing portion 3A of the washing tube 3 and moved upward. After being lifted and removed from the cleaning pipe 3 so as to get over the water guide section 3B, the upper and lower conveyors 13U, 13L of the draining line 2 from the end of the upper / lower conveyors 12U, 12L of the second cleaning line 1A Change to the beginning. In the draining line 2, the fish body F is sandwiched from the upper and lower sides by the upper and lower conveyors 13U and 13L and is conveyed in the right direction in FIG. 1 (refer to the thick arrows in FIG. 1). Although not described, draining is performed by a known method such as air injection.
[0026]
After the draining in the draining line 2 is finished, the fish F is then transferred to a known processing line, subjected to predetermined processing such as three-sheet lowering and vacuum packing, and then shipped as a processed fish food.
[0027]
As described above, according to the fish body cleaning apparatus 1 of the present embodiment, in the first cleaning line 1A and the second cleaning line 1B, cleaning water is sprayed from the cleaning pipe 3 to clean the fish body F from the inner peripheral side. Therefore, compared to the conventional structure in which cleaning water is sprayed only from the outer peripheral side to the upper and lower surfaces, blood and other dirt attached to the internal removal portion on the inner peripheral side of the fish F can be sufficiently removed. As a result, the fish F can be sufficiently cleaned. This also makes it possible to improve the quality and flavor of the processed product.
[0028]
In the above embodiment, the cleaning water is introduced into the cleaning tube 3 from the direction opposite to the direction of transport of the fish F. On the other hand, the cleaning water may be introduced in the same direction as the direction of transport of the fish F. . In this case, the same effect is obtained.
[0029]
【The invention's effect】
According to the present invention, since the fish body is washed from the inner circumference side, compared to the conventional structure in which washing water is sprayed only from the outer circumference side to the upper and lower surfaces, blood and other substances attached to the internal removal portion on the inner circumference side of the fish body Dirt can be removed sufficiently. As a result, the fish body can be sufficiently cleaned.
