Description

  The present invention relates to a device for separating nasal cartilage contained in a fish head from the inside thereof.

  Conventionally, it has been clarified that useful substances such as chondroitin sulfate that can be used for health foods, pharmaceuticals, and the like can be extracted from the head of fish, particularly nasal cartilage.

  As a fish nasal cartilage separation device for taking out the nasal cartilage from the fish head, after heating and softening the fish head, the rotational force on the fish head and the impact force accompanying this rotational force, There is one that separates the head of fish into nasal cartilage and the other (see, for example, Patent Document 1).

  The separation device disclosed in Patent Document 1 includes a hot water pot that is heated when a fish head is immersed therein, and a rotatable drum into which the heated fish head is charged. The drum has a mesh-like portion that allows the inside and the outside to communicate with each other on the peripheral wall portion, and has a plate blade that rises from the inner side surface of the peripheral wall portion toward the axial center side.

  In this fish nasal cartilage separation device, first, the head of the fish is immersed in hot water in a hot water pot so that the head of the fish is easily collapsed. Next, the fish head is lifted from the kettle and placed in the drum. The head of fish is separated into nasal cartilage and residues such as epidermis, muscles, gills, and bones by the rotational force of the drum and the impact force accompanying the rotational force. Then, the separated residue is discharged out of the drum from the mesh portion, whereby the nasal cartilage can be collected from the outlet of the drum.

However, since the fish head is lifted from the kettle and then put into the drum, the time and labor involved in this work are required, which is inefficient. In addition, this drum is not equipped with a mechanism for transporting the fish head, nasal cartilage, etc. from the inlet to the outlet of the drum, so that the fish head, nasal cartilage, etc. adhere to the inner wall of the drum, etc. By staying in the middle of the drum, there is a disadvantage that the separation process may stay.
Japanese Patent Laid-Open No. 11-206311

  In view of such circumstances, an object of the present invention is to provide a fish nasal cartilage separation device that can efficiently separate nasal cartilage from the head of fish without stagnation.

  In order to achieve such an object, the fish nasal cartilage separation device of the present invention has a cylindrical shape having an inlet at one end and a discharge outlet at the other end, and has a circular arc when viewed from the axial direction. A spiral surface body disposed in the container in the axial direction of the container and rotatable, and a plurality of water vapor outlets disposed in the container in the axial direction of the container; The planar surface has a plurality of agitating members on a spiral surface, rotates the spiral surface, and ejects water vapor from the water vapor ejection port, whereby the head of the fish introduced from the injection port is While transporting to the discharge port, the head of the fish is heated and separated into nasal cartilage and residues other than nasal cartilage.

  In the fish nasal cartilage separation device according to the present invention, the head of the fish introduced into the container from the insertion port provided on one end side of the container has the helical surface along with the rotation of the helical surface body. By being pushed to the other end side of the container, it is conveyed from the charging port toward the discharge port. Since the lower surface of the container has an arc shape when viewed from the axial direction, the fish head is reliably pushed by the spiral surface and is prevented from staying in the container.

  Part of the water vapor ejected from the water vapor ejection port leaks out of the container through the charging port and the discharge port because the container is cylindrical and the charging port and the discharge port are open. However, since the container is partitioned by the spiral surface of the spiral surface body, the container is filled. While being transported toward the discharge port, the head of the fish thrown into the container is steamed by the water vapor filled in the container and is easily collapsed.

  The head of the fish, which is in a state of being easily collapsed, is collided with the stirring member that rotates with the rotation of the helical face while being transported toward the discharge port, or the head of the stirring member It is pushed in the rotational direction by a collision, and receives an impact by colliding with the inner wall surface of the container, the spiral surface body, or the like. By this impact, the head of the fish is separated into nasal cartilage and residues other than nasal cartilage while being transported toward the discharge port.

  Since the separated nasal cartilage and the residue contain moisture due to water vapor, the nasal cartilage and the residue are easily attached to the inner wall surface of the container, the spiral surface body, and the like. However, the separated nasal cartilage and residue are frequently moved in the container by being pushed by the spiral face of the spiral face or pushed in the rotational direction by the collision of the stirring member. Without adhering to the inner wall surface or the helical surface of the container and staying in the container, it is transported toward the discharge port and finally discharged from the discharge port to the outside of the container.

  Further, in the fish nasal cartilage separation device, the head of the fish introduced from the insertion port is steamed in the container to be easily collapsed and separated into nasal cartilage and residue. Unlike the fish nasal cartilage separation apparatus, the labor and energy associated with the operation of lifting the fish head from the kettle and putting it into the drum is efficient.

  Therefore, according to the present invention, it is possible to realize a fish nasal cartilage separation device that can efficiently separate nasal cartilage from the head of fish without stagnation.

  In the fish nasal cartilage separation device according to the present invention, it is preferable that the plurality of stirring members are arranged more at both ends than in the axial center of the spiral face.

  On one end side of the container in which a large number of the stirring members are disposed, the heads of the plurality of fish are spaced apart from each other by colliding with a number of the stirring members. Becomes large and becomes easy to be steamed. Further, in the central portion of the container where the stirring member is disposed less than the both end portions, the heads of the plurality of fish are less frequently collided with the stirring member, so that they are closely packed together. Separation is facilitated by collisions. Further, on the other end side of the container in which many stirring members are arranged, the plurality of fish heads collide with many stirring members and receive impact, thereby further promoting separation. .

  In the fish nasal cartilage separation device according to the present invention, it is preferable that one end side of the container is provided wider than the other end side of the spiral surfaces adjacent to each other.

  According to this configuration, since a large amount of water vapor is distributed in the interval, the head of the fish located in the interval is easily steamed. Further, since the gap is wide at one end of the container where there are many fish heads that are large because the separation is not so advanced, the fish heads stay in the gaps. Can be prevented.

  In the fish nasal cartilage separation device of the present invention, it is preferable that one end of the container is inclined downward at an angle of 15 ° or less with respect to the horizontal direction.

  The angle of the container may be horizontal, but by tilting the container at such an angle, the head of the fish in the container is pressed against the helical surface by its own weight, and the helical surface body is rotated. It is pressed in the direction opposite to the accompanying transport direction. As a result, the head of the fish stays in the container for a long time, and the steaming time becomes longer.

  When the angle at which the one end side of the container is inclined downward with respect to the horizontal direction exceeds 15 °, the action of the fish head being pressed against the spiral surface becomes too large, and the spiral shape Excessive energy is required to rotate the face, which is inefficient.

  In the fish nasal cartilage separation device according to the present invention, it is preferable that the plurality of water vapor outlets are disposed more on one end side than on the other end side of the container.

  According to this configuration, a large amount of water vapor spouts at one end of the vessel where there are many heads of the fish that have not been separated so much, so the head of the fish comes into contact with a large amount of water vapor. , Easy to be steamed.

  Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is an explanatory perspective view showing a configuration example of a fish nasal cartilage separation device according to this embodiment. For illustration, the wall surface of the container and a part of the water vapor supply pipe are notched in the drawing.

  The fish nasal cartilage separation device 1 includes a cylindrical container 2, a spiral face 3 disposed in the axial direction in the container 2, and a water vapor supply pipe 4 extending in the container 2, This is a device for separating the head 21 into nasal cartilage 22 and residues 23 other than nasal cartilage 22. The spiral surface body 3 is obtained by providing a spiral surface 6 on the outer peripheral surface of the shaft member 5.

  The container 2 is a cylindrical container whose bottom surface has an arc shape when viewed from the axial direction, a container main body 7 having a U-shaped cross-sectional shape, and a lid 8 that covers an opening on the upper surface of the container main body 7. Consists of. The container 2 is supported by two sets of leg portions 9 and 10, and is installed so that the inlet side of the container 2 is inclined downward by 10.45 ° with respect to the horizontal direction.

  The lid 8 is partially cut away at the portion corresponding to the inlet side of the container 2 when the upper surface of the container body 7 is covered, and a hopper 11 is provided at the notched portion. The hopper 11 serves as a loading port 11 for loading the bag head 21 into the container 2.

  In addition to the upper surface, the container body 7 is further open at both ends. One end of the shaft member 5 of the spiral face 3 extends out of the container body 7 from the opening on the inlet side of the container body 7. In the vicinity of the opening on the outlet side of the container body 7, a part of the lower surface is notched, and a hollow cylinder 12 is provided in the notch. The cylindrical body 12 serves as a discharge port 12 for discharging the contents of the container body 7 to the outside of the container 2. A receiving container 13 for receiving the discharged contents is provided immediately below the discharge port 12.

  The spiral face 3 is supported by bearing members 14 and 15 provided on one end side of the shaft member 5 outside the container 2, and the bearing member provided on the outlet side of the container 2 on the other end side of the shaft member 5. By being supported by 16, it is arranged in the container 2 without contacting the lower surface of the container 2. The helical surface 3 is configured such that the content in the container 2 is transferred to the container 2 by using a drive roller (not shown) connected by a chain / sprocket mechanism 17 provided at one end of the shaft member 5 with the shaft member 5 as a rotation shaft. It is designed to rotate in the direction of transport from the inlet side to the outlet side.

  The spiral surface body 3 is formed by winding one surface around the outer peripheral surface of the shaft member 5 spirally for 23 rounds. The surface for one round is referred to as a spiral surface 6. The space | interval of the mutually adjacent spiral surface 6 is provided more widely in the inlet side of the container 2 than the outlet side. Further, the spiral surface 6 is provided with a stirring member 18 that connects the spiral surfaces 6 adjacent to each other. One stirring member 18 is provided for one spiral surface 6 on the inlet side and the outlet side of the container 2, and one stirring member 18 is provided for two spiral surfaces 6 on the central portion.

  The water vapor supply pipe 4 extends in the axial direction of the container 2 at the upper part in the container 2 and includes a plurality of water vapor outlets 19. The plurality of water vapor outlets 19 are provided so as to face the lower surface in the container 2, and are provided more on the inlet side than on the outlet side of the container 2.

  The stirring member 18 connects the spiral surfaces 6 adjacent to each other. However, the stirring member 18 is a protruding member that is shorter than the interval between the adjacent spiral surfaces 6 and protrudes parallel to the axial direction from the spiral surface 6. There may be.

  Next, the operation of the fish nasal cartilage separation device 1 of this embodiment will be described. First, in a state where the opening on the upper surface of the container body 7 is covered with the lid 8, water vapor of 0.1 MPa and 100 ° C. is ejected into the container 2 from the water vapor outlet 19. Although some of the water vapor leaks out of the container 2 from the inlet 9 and the outlet 12 because the container 2 is cylindrical and the inlet 9 and outlet 12 are open, the container 2 is spiral. Since it is partitioned by the spiral surface 6 of the face body 3, the container 2 is filled. Next, the chain / sprocket mechanism is activated to rotate the spiral face 3 at a speed of 2 revolutions per minute. Next, the head portion 21 of the bag is introduced into the container 2 from the insertion port 9.

  The head 21 of the jar introduced into the container 2 is pushed toward the outlet side of the container 2 by the spiral surface 6 with the rotation of the spiral surface body 3, thereby moving from the inlet 9 toward the outlet 12. Transported. Since the lower surface of the container 2 has an arc shape when viewed from the axial direction, the head portion 21 of the bag is reliably pushed by the spiral surface 6 and is prevented from staying in the container 2.

  While being transported toward the discharge port 12, the head portion 21 of the candy introduced into the container 2 is steamed by the water vapor filled in the container 2, and is easily collapsed.

  While being transported toward the discharge port 12, the head portion 21 of the heel that is in a state of being easily collapsed is collided with the stirring member 18 that rotates as the spiral face 3 rotates, or the stirring member 18. It is pushed in the rotation direction by the collision of the container, and receives an impact by colliding with the inner wall surface of the container 2, the spiral surface body 3 or the like. Due to this impact, the head 21 of the heel is separated into nasal cartilage 22 and residues 23 such as epidermis, muscle, gills, and bones other than nasal cartilage 22 while being transported toward discharge port 12.

Since the separated nasal cartilage 22 and the residue 23 contain moisture due to water vapor, the nasal cartilage 22 and the residue 23 are easily attached to the inner wall surface of the container 2, the spiral surface body 3, and the like. However, since the separated nasal cartilage 22 and the residue 23 are pushed by the spiral surface 6 of the spiral face 3 or pushed in the rotational direction by the collision of the stirring member 18, their positions are frequently moved. , Without adhering to the inner wall surface of the container 2 or the spiral surface body 3 and staying in the container 2, it is transported toward the discharge port 12 and finally discharged from the discharge port 12 to the outside of the container 2 and dropped. In the receiving container 13.

  Further, in the fish nasal cartilage separation device 1, the head 21 of the salmon introduced from the insertion port 9 is steamed in the container 2 to be easily collapsed and separated into the nasal cartilage 22 and the residue 23. Therefore, unlike the fish nasal cartilage separation device of the prior art, it does not require the labor and energy associated with the operation of lifting the fish head from the kettle and putting it in the drum, which is efficient.

  Therefore, according to the present invention, it is possible to realize a fish nasal cartilage separation device that can efficiently separate nasal cartilage from the head of fish without stagnation.

  Further, in the fish nasal cartilage separation device 1, the plurality of stirring members 18 are arranged more at both ends (inlet side and outlet side) than the central part in the axial direction of the spiral face 3. As a result, on the inlet side of the container 2 where a large number of stirring members 18 are arranged, the heads 21 of the plurality of baskets are spaced apart from each other by colliding with the many stirring members 18, so The contact area becomes large and it becomes easy to be steamed. In addition, in the central part of the container 2 where the stirring members 18 are disposed less than both ends, the plurality of heel heads 21 are less frequently collided with the stirring members 18, so Separation promotes separation. Further, on the outlet side of the container 2 where a large number of stirring members 18 are arranged, the plurality of heads 21 of the baskets collide with the many stirring members 18 and receive an impact, thereby further promoting the separation.

  Further, in the fish nasal cartilage separation device 1, the space between the spiral surfaces 6 adjacent to each other of the spiral surface body 3 is wider than the side corresponding to the inlet side of the container 2 than the side corresponding to the outlet side. Since a large amount of water vapor easily flows in the interval, the head 21 of the cocoon located in the interval is easily steamed. In addition, since the gap is wide on the inlet side of the container 2 where there are a large number of scissor heads 21 that are large because separation has not progressed much, the scissor heads 21 stay in the spacing. Can be prevented.

  In the fish nasal cartilage separation device 1, the container 2 is inclined 10.45 ° downward on the entrance side with respect to the horizontal direction, so that the head 21 of the salmon in the container 2 is placed on the spiral surface 6 by its own weight. It is pressed and pressed in the direction opposite to the conveying direction accompanying the rotation of the helical face 3. As a result, the salmon head 21 stays in the container 2 for a long time, and the steaming time becomes longer. In addition, it is good for the container 2 to incline below by the angle within 15 degrees with respect to a horizontal direction at the entrance side. If the angle exceeds 15 °, the action of pressing the head portion 21 of the heel against the spiral surface 6 becomes too large, and excessive energy is required to rotate the spiral surface body 3, which is inefficient. .

  Further, in the fish nasal cartilage separation device 1, the plurality of water vapor jets 19 are arranged more on the inlet side than on the outlet side of the container 2. As a result, a large amount of water vapor spouts out at the inlet side of the container 2 where there are many head portions 21 of the soot that are not so separated, so that the head portion 21 of the soot comes into contact with a large amount of water vapor and is steamed. It becomes easy.
