Currently, salmonids and trouts, for example, are eaten globally, and resource conservation has been established through improved aquaculture technology and the development of the global hatching business. ing. And the fish eggs that these fish have have gained popularity among consumers. In general, a fish egg grows from an initial egg to a mature egg in the body of a female fish, but the egg grains are in a state of being connected to a muscle inside the bag-shaped skin (bag skin). And, fish eggs such as salmon, trout, etc. that are taken out in a state in which the eggs are wrapped in the bag skin are called muscles, and those obtained by separating only the eggs from the bag skin are called salmon roe. .
[0003]
In order to take out the salmon roe, it is necessary to separate only the egg grains existing in the pouch skin from the pouch skin and the muscle. However, the eggs are delicate, and the operation of separating the eggs from the bag skin is difficult to mechanize because it is necessary to prevent the eggs from being crushed. For this reason, the operation | work which isolate | separates an egg grain from such a bag skin and a muscle conventionally was performed by manual work.

[0037]
The individual components such as the mesh belt 20 and the rollers 12, 14, 16 of the fish egg separator 1 are configured so that they can be easily disassembled.
[0038]
Next, the operation of the fish egg separator 1 according to the embodiment of the present invention will be described.
[0039]
First, as shown in FIG. 3, the muscle (the egg particle 100 wrapped in the bag skin 101) is opened from one end in the longitudinal direction, and the egg particle 100 is supplied so as to be in contact with the surface of the mesh belt 20. (See FIG. 4). At that time, the mesh belt 20 moves in the direction of the arrow in FIG.
[0040]
The egg 100 with the bag skin 101 supplied to the surface of the mesh belt 20 moves to the position of the first roller 12, and its tip is sandwiched between the first roller 12 and the mesh belt 20, so that the first 1 roller 12 is pressed. Then, as shown in FIG. 5, the egg grains 100 gradually become about half of the egg grains 100 due to the conveying operation of the mesh belt 20 and the rotating operation of the first roller 12. It is extruded from 20a to the back side of the mesh belt 20.
[0041]
Next, the egg 100 with the bag skin 101 is moved to the position of the second roller 14 by the conveying operation of the mesh belt 20, and the tip portion is sandwiched between the second roller 14 and the mesh belt 20, and It is pressed by the second roller 14. At this time, as shown in FIG. 6, the convex portion 14 a provided on the surface of the second roller 14 enters the mesh hole 20 a of the mesh belt 20, so that the egg grains with the conveyed bag skin 101 are attached. Most of the eggs 100 out of 100 are pushed out to the back side of the mesh belt 20.
[0042]
Further, the egg belt 100 with the bag skin 101 is moved to the position of the third roller 16 by the movement of the mesh belt 20, and the tip portion is sandwiched between the third roller 16 and the mesh belt 20 so that the first The pressure is received by the three rollers 16. At this time, the convex portion 16a provided on the surface of the third roller 16 enters the mesh hole 20a when the third roller 16 rotates, and the convex portion 16a protrudes from the mesh hole 20a. For this reason, the eggs 100 attached to the bag skin 101 can be easily separated from the bag skin 101 (see FIG. 7). At this time, the tip of the scraping blade 19 disposed in the vicinity of the lower end portion of the convex portion 16 a protruding downward from the mesh belt 20 is brought into contact with the egg skin 100 between the bag skin 101 and the muscle that are conveyed. As a result, only the eggs 100 are separated from the pouch skin 101 while the muscles are released by the protrusions 19b of the scraping blade 19.
[0043]
Then, the salt water cooled by the salt water shower 18 is sprayed on the eggs 100 separated from the bag skin 101. Thereby, while being able to hold | maintain the freshness of the said egg particle 100, an egg particle is crushed in the vicinity of the said 1st roller, the 2nd roller 14, the 3rd roller 16, and the scraping blade 19, and protein, fat, etc. Even when the soup flows out and changes to a white and sticky soup, such soup can be washed away.
[0044]
In this way, when passing through the third roller 16, the egg particles 100 and the bag skin 101 are separated, and the separated egg particles 100 are collected at a predetermined location.
[0045]
Further, the bag skin 101 separated from the egg grains 100 adheres to the surface of the mesh belt 20 and moves together with the mesh belt 20. The bag skin 101 on the mesh belt 20 passes on the drive pulley 22 and moves toward the brush roller 26. When the bag skin 101 on the mesh belt 20 moves to the position of the brush roller 26, the mesh belt 20 is attached to the bag skin 101 attached to the mesh belt 20 by the brush of the brush roller 26 that has entered the mesh hole 20a. The force which extrudes the bag skin 101 from the back side works. At the same time, air is jetted from the air jetting unit 28 toward the mesh belt 20. The bag skin 101 is peeled off from the surface of the mesh belt 20 by the pushing force of the brush roller 26 by the brush and the wind pressure of the air, and sent to the discharge chute 30 (see FIG. 9).
[0046]
Therefore, according to the present embodiment, by using the plurality of rollers 12, 14, 16 and the mesh belt 20, it is possible to easily separate the bag skin 101 and the egg grains 100 in a short time. Specifically, the egg belt 100 with the bag skin 101 is pressed by the first roller 12, the second roller 14, and the third roller 16, so that only the egg particle 100 is transferred from the mesh hole 20 a to the mesh belt. The bag skin 101 and the egg 100 can be easily and reliably separated by the scraping blade 19.
[0047]
Further, since the egg particles 100 can be gradually pushed out to the back side of the mesh belt 20 by using a plurality of rollers 12, 14, 16, the burden on the egg particles 100 can be reduced, and the egg particles 100 can be reduced. Can be prevented from being crushed.
[0048]
Further, the bag skin 101 is peeled off from the mesh belt 20 by applying pressure to the mesh belt 20 with the brush roller 26 on the bag skin 101 on the mesh belt 20 that has passed through the plurality of rollers 12, 14, 16. It can be discharged outside the egg separator 1.
[0049]
Further, air is ejected from the air ejecting unit 28 to the bag skin 101 moving on the mesh belt 20, so that the bag skin 101 is easily peeled off from the mesh belt 20 along with the pressure applied by the brush roller 26. be able to.
[0050]
Further, by spraying salt water from the salt water shower 18 onto the egg grains 100, there is adhesiveness from a small amount of the crushed egg grains 100 generated in the vicinity of the first roller 12, the second roller 14, and the third roller 16. Since the juice is washed away, the quality of the normal egg grains 100 that are not crushed can be maintained. Moreover, the freshness of the egg particle 100 can be maintained by applying salt water to the egg particle 100.
[0051]
Furthermore, the egg grains 100 exist in a continuous manner with the muscles in the bag skin 101, and when the egg grains 100 are pushed out to the back side of the mesh belt 20, the muscles are pushed out. Since the blade 19 is provided with a projection 19b, and the muscle escapes by the projection 19b on the surface of the scraping blade 19, only the egg 100 is removed from the bag skin 101 without cutting the muscle from the bag skin 101. Can be cut from the line. For this reason, when separating the egg grains 100 from the bag skin 101, it is possible to prevent inclusion of foreign matters such as muscles.
[0052]
Further, since the mesh belt 20 is formed of a thin wire 20b having a diameter of 1 mm, the mesh belt 20 can be pushed out from the mesh hole 20a to the back side of the mesh belt 20 so as not to crush more eggs 100, Yield can be further improved.
[0053]
Furthermore, the fish egg separator 1 is configured to be disassembled into individual parts with a single touch, and can be easily disassembled and washed for each individual part. 1 hygiene can be maintained. As a result, the egg particles 100 can be separated from the bag skin 101 in a sanitary manner.
[0054]
In addition, this invention is not limited to the said embodiment, A various change is possible as needed.
[0055]
【The invention's effect】
