Description

本発明は、魚類の頭部からその内部に含まれている鼻軟骨を分離する装置に関する。   The present invention relates to a device for separating nasal cartilage contained in a fish head from the inside thereof.

従来より、魚類の頭部、特に鼻軟骨部分から健康食品や医薬品等に利用可能なコンドロイチン硫酸等の有用物質が抽出できることが明らかになっており、この頭部から鼻軟骨を取り出すために種々の工夫がなされている。例えば、下記特許文献1に開示されている装置は、外周壁面が網目状の円筒状のドラムと、その内周面に起立して取り付けられた板羽根とを有し、このドラムの中に加熱した魚類の頭部を入れてドラムを回転させ、頭部をドラムの内周面や板羽根に衝突させて頭骨の周囲に付着している皮、筋肉、エラ、或いは硬骨等を分離させ、この分離した皮等を網目からドラムの外周に排出し、ドラムの出口から鼻軟骨を回収するものである。   Conventionally, it has been clarified that useful substances such as chondroitin sulfate that can be used for health foods and pharmaceuticals can be extracted from the head of fish, particularly nasal cartilage, and various kinds of nasal cartilage can be extracted from this head. Ingenuity has been made. For example, an apparatus disclosed in the following Patent Document 1 has a cylindrical drum whose outer peripheral wall surface is mesh-like, and plate blades that are erected and attached to the inner peripheral surface. The head of the fish is inserted and the drum is rotated, and the head collides with the inner peripheral surface of the drum and the blade of the drum to separate the skin, muscles, gills, bones, etc. attached around the skull. The separated skin and the like are discharged from the mesh to the outer periphery of the drum, and the nasal cartilage is collected from the outlet of the drum.

ところが、本件発明者等が実験したところによれば、頭部から鼻軟骨部分を含む頭骨が分離できるものの、分離されるものの中には鼻軟骨の他に不要な前頭骨(硬骨)も混入することが多く、鼻軟骨のみを分離することが困難であった。この前頭骨は、鼻軟骨よりは小さいが残渣の中では最大の大きさを有している。従って、前記特許文献1に開示されている装置において、前記ドラムの網目の大きさを前頭骨が通過できる大きさにすることも考えられる。前記ドラムの網目の大きさをそのような大きさにした場合、前記前頭骨が前記網目を通過するため前記前頭骨を分離することが可能となる。   However, according to an experiment conducted by the present inventors, although the skull including the nasal cartilage portion can be separated from the head, unnecessary frontal bones (bones) are also mixed in the separated matter in addition to the nasal cartilage. In many cases, it was difficult to isolate only the nasal cartilage. This frontal bone is smaller than the nasal cartilage but has the largest size among the residues. Therefore, in the apparatus disclosed in Patent Document 1, it is also conceivable that the size of the mesh of the drum is set to allow the frontal bone to pass. When the mesh size of the drum is set to such a size, the frontal bone can be separated because the frontal bone passes through the mesh.

しかしながら、このように網目を大きくしたのでは、鼻軟骨の一部が前記網目に入り込むことが多く、その状態で他の残渣等の重量がかかる等の理由により、鼻軟骨の一部が折れて網目から外部に排出されてしまうことがあった。これでは、鼻軟骨以外の残渣はほぼ分離できるが、肝心の鼻軟骨の回収率が低下してしまうという不都合がある。
特開平11−206311号公報
However, when the mesh is increased in this way, a part of the nasal cartilage often enters the mesh, and part of the nasal cartilage is broken due to the weight of other residues in that state. In some cases, it was discharged outside through the mesh. In this case, residues other than nasal cartilage can be separated substantially, but there is a disadvantage that the recovery rate of nasal cartilage is important.
Japanese Patent Laid-Open No. 11-206311

本発明は、魚類頭部の鼻軟骨分離装置の改良を目的とし、さらに詳しくは前記不都合を解消するために、魚類の頭部の内、前頭骨を含む不要な残渣を分離できると共に鼻軟骨の回収率が高い分離装置を提供することを目的とする。   An object of the present invention is to improve a nasal cartilage separation device for a fish head. More specifically, in order to eliminate the inconvenience, an unnecessary residue including a frontal bone can be separated from a fish head and nasal cartilage can be separated. An object is to provide a separation apparatus having a high recovery rate.

前記目的を達成するために、本発明の魚類頭部の鼻軟骨分離装置は、魚類の頭部から鼻軟骨を分離する装置であって、中空円筒状で回転自在の回転ドラムと、前記回転ドラムを水平方向に保持する支持体と、前記回転ドラムを駆動する駆動手段とを有し、前記回転ドラムは前記頭部が投入される投入口と、前記頭部から分離された鼻軟骨が吐出される吐出口と、前記投入口と吐出口との間に設けられた円筒部とを有し、前記円筒部は、外周面が相互に間隔を存して軸方向に内外2重に配設された棒部材で形成され、内部には内方の棒部材の表面から内方に起立して軸方向に螺旋状に延びる案内板が設けられ、前記棒部材の間隔が前記鼻軟骨は通過させず、前記頭部から分離された前頭骨を含む残渣は通過させる間隔となっており、前記回転ドラムは、前記円筒部と前記吐出口との間に前記吐出口に向けて縮径する円錐台状の円錐部が設けられ、前記円筒部の外周面に、前記円錐部の端部から前記投入口側に向けて所定の長さの板状の円筒カバーが取り付けられていることを特徴とする。 In order to achieve the above object, a nasal cartilage separation device for a fish head according to the present invention is a device for separating nasal cartilage from a fish head, and is a hollow cylindrical rotatable drum and the rotary drum. And a driving means for driving the rotary drum. The rotary drum has a slot into which the head is inserted, and nasal cartilage separated from the head is discharged. And a cylindrical portion provided between the charging port and the discharge port, and the cylindrical portion is disposed in an inner and outer double manner in the axial direction with the outer peripheral surfaces spaced apart from each other. A guide plate is provided in the interior, and is provided with a guide plate that erects inward from the surface of the inner rod member and extends spirally in the axial direction, and the interval between the rod members does not allow the nasal cartilage to pass therethrough. , the residue containing the skull before separated from the head has a gap for passing the rotary de The cone is provided with a frustoconical conical portion that is reduced in diameter toward the discharge port between the cylindrical portion and the discharge port, and is inserted into the outer peripheral surface of the cylindrical portion from the end of the conical portion. A plate-like cylindrical cover having a predetermined length is attached toward the mouth side .

本発明の魚類頭部の鼻軟骨分離装置によれば、前記投入口より投入された魚類の頭部は、前記回転ドラムの円筒部内で前記棒部材に衝突しながら前記案内部材によって前記吐出口側に運ばれる。前記円筒部は、その外周面が所定の間隔を有する棒部材によって形成されているため、当該棒部材の間隔を通過しない鼻軟骨は前記吐出口まで運ばれる。一方、前頭骨を含む残渣は前記棒部材の間隔を通過するので、円筒部の外部に排出される。   According to the fish head nasal cartilage separation device of the present invention, the fish head thrown in from the slot is collided with the rod member in the cylindrical portion of the rotating drum while the guide member moves the discharge port side. Carried to. Since the cylindrical portion is formed by rod members having an outer peripheral surface having a predetermined interval, nasal cartilage that does not pass through the interval between the rod members is conveyed to the discharge port. On the other hand, since the residue including the frontal bone passes through the space between the rod members, it is discharged outside the cylindrical portion.

ここで、残渣の中で最大の大きさを有する前頭骨は、その大きさが魚類の大きさによって左右されるが、その厚さはその魚類の大きさにさほど左右されない。本発明の装置によれば、前記円筒部の外周面が棒部材の組合せによりできているため、当該棒部材の軸方向の長さは前記前頭骨の大きさに比べて十分長いので、前記棒部材の間隔が前記前頭骨の厚さよりも広ければよい。従って、前記棒部材の間隔は従来の網のように大きくすることなく、前記鼻軟骨は通過させず前記前頭骨を含む残渣のみを通過させることが可能となる。   Here, the size of the frontal bone having the largest size among the residues depends on the size of the fish, but its thickness is not so much affected by the size of the fish. According to the apparatus of the present invention, since the outer peripheral surface of the cylindrical portion is made of a combination of rod members, the axial length of the rod member is sufficiently longer than the size of the frontal bone. It is only necessary that the distance between the members is wider than the thickness of the frontal bone. Accordingly, it is possible to allow only the residue including the frontal bone to pass through without passing through the nasal cartilage without increasing the interval between the rod members as in the conventional net.

また、前記円筒部の外周面が軸方向に内外2重に配設された棒部材となっているので、前記頭部はまず内周側の棒部材に衝突し、次に外周側の棒部材に衝突することになる。このように、当該構成により前記頭部が前記棒部材に衝突する回数が多くなるため、単に棒部材を1重の円周状に配設した場合に比べて前記鼻軟骨から他の部分を分離しやすい。   In addition, since the outer peripheral surface of the cylindrical portion is a rod member that is disposed in an inner and outer double in the axial direction, the head first collides with the inner rod member, and then the outer rod member. Will collide with. In this way, the number of times that the head collides with the rod member increases due to this configuration, so that the other parts are separated from the nasal cartilage as compared with the case where the rod member is simply arranged in a single circumferential shape. It's easy to do.

また、前記回転ドラムは、前記円筒部から前記円錐部によって縮径されて前記吐出口につながるため、前記吐出口の径を小さくすることができる。このため、前記吐出口から吐出される鼻軟骨の回収が容易となる。 The front Symbol rotary drum, because it leads to the discharge port from the cylindrical portion being reduced in diameter by the conical portion, it is possible to reduce the diameter of the discharge port. For this reason, the collection | recovery of the nasal cartilage discharged from the said discharge outlet becomes easy.

また、本発明の魚類頭部の鼻軟骨分離装置においては、前記円筒部の外周面に、前記円錐部の端部から前記投入口側に向けて所定の長さの板状の円筒カバーが取り付けられていることにより、前記棒部材の隙間から前記鼻軟骨の一部が突出することが防止されるため、前記鼻軟骨を円滑に前記円錐部に案内することができる。
また、前記円錐部に設けられた案内部材には貫通孔が設けられていることが好ましい。これにより、前記鼻軟骨は前記貫通孔によって前記案内部材の表面を滑りにくくなるので、前記鼻軟骨が前記円錐部を上昇して前記吐出口まで円滑に案内される。
In the nasal cartilage separation device for a fish head according to the present invention, a plate-shaped cylindrical cover having a predetermined length is attached to the outer peripheral surface of the cylindrical portion from the end of the conical portion toward the inlet side. is by a Turkey have, the order in part from the gap of the rod member of the nasal cartilage is prevented from projecting, it can be guided by the conical portion smoothly the nasal cartilage.
Moreover, it is preferable that the guide member provided in the conical part is provided with a through hole. As a result, the nasal cartilage is less likely to slip on the surface of the guide member due to the through-hole, so that the nasal cartilage ascends the conical portion and is smoothly guided to the discharge port.

また、本発明の魚類頭部の鼻軟骨分離装置においては、前記回転ドラムの外周を囲むと共に前記回転ドラムの下方に開口を有するハウジングと、前記開口の下方に設置される残渣回収容器とが設けられていることが好ましい。前記回転ドラムが回転すると、前記頭部から分離された残渣が前記棒部材の間隔から遠心力で外部に排出されるが、前記ハウジング及び前記残渣回収容器によってこれらが散乱することなく回収される。従って、当該構成により残渣の回収も容易となる。   In the nasal cartilage separation device for a fish head according to the present invention, a housing that surrounds the outer periphery of the rotating drum and has an opening below the rotating drum, and a residue collection container that is installed below the opening are provided. It is preferable that When the rotating drum rotates, the residue separated from the head is discharged to the outside by a centrifugal force from the interval between the rod members, but these are recovered without being scattered by the housing and the residue recovery container. Therefore, the recovery of the residue is facilitated by this configuration.

また、本発明の魚類頭部の鼻軟骨分離装置においては、前記魚類が鮭であるときは、前記棒部材は前記円筒部を軸方向から見たときに隣り合う外方の棒部材と近接する内方の棒部材とが正三角形の頂点となるように配設され、それぞれの棒部材の間隔が18mmから22mmとなっていることが好ましい。前記魚類が鮭の場合、その前頭骨の厚さはほぼ10mmから20mm程度である。一方、鮭の鼻軟骨の厚さは約30mm以上となっている。従って、前記円筒部の棒部材の間隔を18mmから22mmとすることにより、鮭の鼻軟骨を排出することなく前頭骨を棒部材の間から排出することができる。   Further, in the fish head nasal cartilage separation device according to the present invention, when the fish is a salmon, the rod member is adjacent to an adjacent outer rod member when the cylindrical portion is viewed from the axial direction. It is preferable that the inner rod members are disposed so as to be the vertices of an equilateral triangle, and the interval between the rod members is 18 mm to 22 mm. When the fish is a salmon, the thickness of the frontal bone is about 10 mm to 20 mm. On the other hand, the thickness of the nasal cartilage is about 30 mm or more. Therefore, by setting the interval between the rod members of the cylindrical portion to 18 mm to 22 mm, the frontal bone can be discharged from between the rod members without discharging the nasal cartilage of the heel.

次に、本発明の鼻軟骨分離装置の実施形態の一例について、図1乃至図4を参照して説明する。鼻軟骨分離装置1は、鮭の頭部からその中に含まれている鼻軟骨部(図4参照)を分離する装置であり、図1及び図2に示すように、回転ドラム2と、この回転ドラム2を回転自在に支持するフレーム3(支持体)と、回転ドラム2を囲むハウジング4と、回転ドラム2内に原料である鮭の頭部を投入するホッパ5と、回転ドラム2から吐出される鼻軟骨部の確認を行う確認台6とを備えている。また、図2に示すように、回転ドラム2を回転させるモーター7及びチェーン8(駆動手段)とを備えている。   Next, an example of an embodiment of the nasal cartilage separation device of the present invention will be described with reference to FIGS. The nasal cartilage separation device 1 is a device for separating the nasal cartilage portion (see FIG. 4) contained therein from the head of the heel, and as shown in FIGS. A frame 3 (support) that rotatably supports the rotating drum 2, a housing 4 that surrounds the rotating drum 2, a hopper 5 that feeds the head of the bag as a raw material into the rotating drum 2, and discharge from the rotating drum 2 And a confirmation table 6 for confirming the nasal cartilage portion. Moreover, as shown in FIG. 2, the motor 7 and the chain 8 (drive means) which rotate the rotating drum 2 are provided.

回転ドラム2は、図1に示すように、円筒状の円筒部21を有しており、その後方部分は開放されて投入口22となっている。また、円筒部の前方には円錐部23が設けられており、この円錐部23の先端側に吐出口24が設けられている。また、円筒部21の前方部分はその外周面が円筒カバー25で覆われている。   As shown in FIG. 1, the rotating drum 2 has a cylindrical cylindrical portion 21, and a rear portion thereof is opened to form an inlet 22. Further, a conical portion 23 is provided in front of the cylindrical portion, and a discharge port 24 is provided on the tip side of the conical portion 23. Further, the outer peripheral surface of the front portion of the cylindrical portion 21 is covered with a cylindrical cover 25.

円筒部21は、図3に示すように、外周部が内外2重の棒部材により形成されており、内側の内棒部材26と外側の外棒部材27とからなる。この内棒部材26の外周と外棒部材27の内周との間には、リングスペーサ28が介在しており、内棒部材26及び外棒部材27は共にリングスペーサ28に溶接されて固定されている。本実施形態においては、内棒部材26及び外棒部材27共に直径6mmの鉄製の棒を用いている。また、図3に示すように、内棒部材26と隣接する2本の外棒部材27は、それぞれを結ぶと正三角形となるように配設されている。そして、それぞれの棒部材の間隔が20mmとなるように形成されている。   As shown in FIG. 3, the cylindrical portion 21 has an outer peripheral portion formed of double inner and outer rod members, and includes an inner inner rod member 26 and an outer outer rod member 27. A ring spacer 28 is interposed between the outer periphery of the inner rod member 26 and the inner periphery of the outer rod member 27, and both the inner rod member 26 and the outer rod member 27 are welded and fixed to the ring spacer 28. ing. In the present embodiment, both the inner rod member 26 and the outer rod member 27 are made of iron rods having a diameter of 6 mm. Further, as shown in FIG. 3, the two outer rod members 27 adjacent to the inner rod member 26 are arranged to form an equilateral triangle when they are connected to each other. And it forms so that the space | interval of each rod member may be 20 mm.

また、円筒部21の内部には、図3に示すように120゜毎に螺旋状の案内板29が内棒部材26の表面に溶接されて設けられている。そして、この案内板29は、円錐部23の内部に延びている箇所では表裏を貫通する貫通孔29aが数カ所に設けられている。   In addition, a spiral guide plate 29 is welded to the surface of the inner rod member 26 every 120 ° as shown in FIG. The guide plate 29 is provided with several through holes 29 a penetrating the front and back at locations extending inside the conical portion 23.

また、図2に示すように、回転ドラム2の後方には回転ドラム2の中心に取り付けられている回転軸30が後方に突出しており、この回転軸30にはチェーン8を介してモーター7が接続されている。このモーター7はインバーター式で回転数を変更可能であるが、回転ドラム2を回転させる際には約60rpmで回転させるようにしている。   As shown in FIG. 2, a rotating shaft 30 attached to the center of the rotating drum 2 protrudes rearward of the rotating drum 2, and the motor 7 is connected to the rotating shaft 30 via a chain 8. It is connected. The motor 7 is of an inverter type and the number of rotations can be changed. However, when the rotating drum 2 is rotated, the motor 7 is rotated at about 60 rpm.

また、本実施形態においては、回転ドラム2は、ハウジング4により覆われている。このハウジング4は上ハウジング4aと下ハウジング4bとからなり、下ハウジング4bの下方には開口4cが設けられている。そして、装置の運転時には、当該開口4cの下方に残渣回収容器31が設置され、回転ドラム2によって分離され外部に飛び出して開口4cから落下する残渣を回収できるようにしている。   In the present embodiment, the rotary drum 2 is covered with the housing 4. The housing 4 includes an upper housing 4a and a lower housing 4b, and an opening 4c is provided below the lower housing 4b. During operation of the apparatus, a residue collection container 31 is installed below the opening 4c so that the residue separated by the rotating drum 2 and jumping out to the outside and dropping from the opening 4c can be collected.

本実施形態において鼻軟骨部が分離される鮭の頭部11は、図4(a)に示すように、エラの後方部分から切り取られた状態で鮭の加工工場等から搬送される。この頭部11には、点線で示す鼻軟骨部12部分が含まれている。この鼻軟骨部12は、頭部11から分離された状態では図4(b)に示すような形状となっている。その長さは鮭自体の大きさに左右されるため約70mmから150mmであるが、その幅は鮭自体の大きさにはあまり左右されず40mmから60mmとなっている。   In this embodiment, the head 11 of the heel from which the nasal cartilage portion is separated is transported from a heel processing factory or the like in a state of being cut off from the rear portion of the gill as shown in FIG. The head 11 includes a nasal cartilage portion 12 indicated by a dotted line. The nasal cartilage portion 12 has a shape as shown in FIG. 4B when separated from the head portion 11. Its length depends on the size of the ridge itself, so it is about 70 mm to 150 mm, but its width is not greatly influenced by the size of the heel itself, but is 40 mm to 60 mm.

また、頭部11から分離される残渣の内、最大のものは図4(c)に示す前頭骨13である。この前頭骨13の長さは鮭自体の大きさに左右されるため約60mmから100mmであるが、その幅は鮭自体の大きさにはあまり左右されず10mmから20mmとなっている。   Of the residues separated from the head 11, the largest one is the frontal bone 13 shown in FIG. The length of the frontal bone 13 is about 60 mm to 100 mm because it depends on the size of the heel itself, but its width is 10 mm to 20 mm without much influence on the size of the heel itself.

次に、本実施形態の鼻軟骨分離装置1の作動について説明する。本実施形態の鼻軟骨分離装置1の運転を開始する場合は、図示しない運転スイッチをオンにすることによりモータ7が回転し、チェーン8によって回転力が回転軸30及び回転ドラム2に伝えられ、回転ドラム2が回転する。   Next, the operation of the nasal cartilage separation device 1 according to this embodiment will be described. When starting the operation of the nasal cartilage separation device 1 of this embodiment, the motor 7 rotates by turning on an operation switch (not shown), and the rotational force is transmitted to the rotating shaft 30 and the rotating drum 2 by the chain 8. The rotating drum 2 rotates.

次に、原料となる鮭の頭部11をホッパ5から投入口22を介して回転ドラム2内に投入する。この頭部11は予めスチームで所定時間加熱され、身やエラ等がほぐれやすいようになっている。回転ドラム2内に投入された頭部11は、内外棒部材26,27や案内板29に衝突して鼻軟骨部12の周囲の皮や身、或いはエラ等が分離される。分離された残渣は、内棒部材26及び外棒部材27の間隔を通過してハウジング4内に飛び出し、下ハウジング4bの開口4cから下方に設けられている残渣回収容器31に収納される。   Next, the head portion 11 of the straw that is a raw material is introduced into the rotary drum 2 from the hopper 5 through the introduction port 22. The head 11 is heated in advance with steam for a predetermined time so that the body, the gills and the like are easily loosened. The head 11 thrown into the rotary drum 2 collides with the inner and outer rod members 26, 27 and the guide plate 29, and the skin, body, and error around the nasal cartilage 12 are separated. The separated residue passes through the space between the inner rod member 26 and the outer rod member 27, jumps into the housing 4, and is stored in a residue collection container 31 provided below from the opening 4c of the lower housing 4b.

そして、頭部11は案内板29によって回転ドラム2の前方に運ばれながら、鼻軟骨部12と他の部分の分離が進んでいく。ここで、頭部11から前頭骨13が分離されると、その厚さはほぼ一定で20mm未満であるため、内外棒部材26,27の間隔から容易に外部に分離可能となっている。一方、鼻軟骨部12は内外棒部材26,27に衝突するものの、内外棒部材26,27は円柱状であるため従来の網のように縁部が鋭利でないので、円筒部21内では鼻軟骨部12がほぼ欠けることがない。   Then, the nasal cartilage portion 12 and other portions are separated while the head portion 11 is carried forward of the rotary drum 2 by the guide plate 29. Here, when the frontal bone 13 is separated from the head 11, its thickness is substantially constant and less than 20 mm, so that it can be easily separated to the outside from the interval between the inner and outer rod members 26 and 27. On the other hand, although the nasal cartilage portion 12 collides with the inner and outer rod members 26 and 27, the inner and outer rod members 26 and 27 are columnar, so the edges are not sharp as in the conventional net, and therefore the nasal cartilage within the cylindrical portion 21. The portion 12 is not substantially missing.

鼻軟骨部12が他の残渣から分離された状態で前記案内板29により円筒部21の前方に搬送されると、円筒部21の外周が円筒カバー25に覆われた箇所に搬送される。この円筒カバー25により覆われた箇所では、鼻軟骨部12の一部が外棒部材27から突出しようとしてもこの円筒カバー25によりその突出が防止される。これにより、鼻軟骨部12の搬送がより容易となる。   When the nasal cartilage portion 12 is separated from other residues and conveyed to the front of the cylindrical portion 21 by the guide plate 29, the outer periphery of the cylindrical portion 21 is conveyed to a location covered with the cylindrical cover 25. In the portion covered with the cylindrical cover 25, even if a part of the nasal cartilage portion 12 tries to protrude from the outer rod member 27, the cylindrical cover 25 prevents the protrusion. Thereby, conveyance of the nasal cartilage part 12 becomes easier.

そして、鼻軟骨部12がさらに前方に搬送されると、円筒部21から円錐部23に搬送される。この円錐部23では、案内板29に貫通孔29aが設けられているため、鼻軟骨部12はこの貫通孔29aによって案内板29の表面を滑ることなく吐出口24まで搬送される。鼻軟骨部12が吐出口24から吐出されると、確認台6の上に落下するので、作業者は落下した鼻軟骨部12を目視で確認しながら次の工程に移送する。   When the nasal cartilage portion 12 is further conveyed forward, it is conveyed from the cylindrical portion 21 to the conical portion 23. In the conical portion 23, the guide plate 29 is provided with the through hole 29 a, so that the nasal cartilage portion 12 is conveyed to the discharge port 24 without sliding on the surface of the guide plate 29 by the through hole 29 a. When the nasal cartilage portion 12 is discharged from the discharge port 24, the nasal cartilage portion 12 falls onto the confirmation table 6. Therefore, the operator moves to the next step while visually confirming the dropped nasal cartilage portion 12.

本実施形態の鼻軟骨分離装置1では、上述のように鼻軟骨部12以外の部分が回転ドラム2の回転によって分離される。特に、分離される部分の内で最大の大きさとなる前頭骨13はその厚さよりもやや大きい間隔を有する内外棒部材26,27の間から遠心力で外部に排出されるので従来の装置のように鼻軟骨部12と共に吐出口24から吐出されることがない。さらに、鼻軟骨部12は内外棒部材26,27の間からは排出されず、衝突する内外棒部材26,27は円柱状であるため鼻軟骨部12の損傷が抑えられる。   In the nasal cartilage separation device 1 according to the present embodiment, parts other than the nasal cartilage portion 12 are separated by the rotation of the rotary drum 2 as described above. In particular, the frontal bone 13 that has the largest size among the separated parts is discharged to the outside by centrifugal force between the inner and outer rod members 26 and 27 having a space slightly larger than the thickness thereof. The nasal cartilage portion 12 is not discharged from the discharge port 24. Further, the nasal cartilage portion 12 is not discharged from between the inner and outer rod members 26 and 27, and the colliding inner and outer rod members 26 and 27 are cylindrical, so that damage to the nasal cartilage portion 12 is suppressed.

尚、上記実施形態においては、棒部材26,27として円柱状の鉄製の棒部材を使用しているが、これに限らず断面形状が楕円形のものや多角形のものを用いても良く、素材も他の素材を用いてもよい。また、上記実施形態においては、駆動手段としてモーター7とチェーン8とを用いているが、これに限らず、小型エンジンや動力伝達ベルト等を用いてもよい。また、前記回転ドラム2はフレーム3により支えられているが、ハウジング4等で指示しても良い。   In the above embodiment, columnar iron rod members are used as the rod members 26 and 27. However, the present invention is not limited to this, and an elliptical or polygonal cross-sectional shape may be used. Other materials may be used as the material.
