Description

TECHNICAL FIELD The present invention relates to a method and an apparatus for separating viscera from shellfish of mussels.

As for mussels such as scallops, scallops are mainly edible. For this reason, fishery product processors and others remove the shells of the mussels, remove the parts (internal organs) other than the adductor muscle, and take out only the adductor muscle. Normally, only the scallops are manually removed one by one, which is very complicated and takes time and effort.

Therefore, Patent Documents 1 and 2 disclose an apparatus and method for capturing an image of the shelled scallop shell, detecting the position of the midgut gland (also called the uro) by image processing, and then separating the uro. is disclosed. Patent Document 3 discloses a method of detecting the position of internal organs by image processing in the same manner as Patent Documents 1 and 2, and then cutting or separating the internal organs.

Patent Document 4 discloses a device that separates the visceral portion from the lower shell and aspirates the adductor muscle and the non-visceral portion (visceral portion) attached to the lower shell, and then separates the adductor muscle from the lower shell. ing.

Patent Document 5 discloses a method of separating the shell from the inner surface of the shell using jet water flow.

Patent Literature 6 discloses a method in which the shelled scallop is set in a separation processing device and rotated at high speed to separate the internal organs from the adductor muscle by centrifugal force.

Patent Documents 7 to 9 disclose a method for separating the mantle (also referred to as string or ear) of the visceral portion of shellfish from other portions (especially uro). Further, Patent Documents 10 to 12 disclose a method for separating the uro, which is the internal organs of shellfish, from other parts (especially string).

Japanese Patent Application Laid-Open No. 2021-35340 Patent No. 6083098 JP-A-2005-102527 Patent No. 6808270 Japanese Patent Application Laid-Open No. 2007-537735 JP-A-53-81677 Japanese Patent Application Laid-Open No. 9-28285 Japanese Patent Application Laid-Open No. 2001-252007 Japanese Patent Application Laid-Open No. 2002-369651 JP-A-3-133332 Utility Model Registration No. 3030356 JP-A-8-280321

The devices and methods disclosed in Patent Documents 1 to 3 automate at least part of the work for separating the uro and viscera. However, a very complicated and expensive device is required for image processing, and processing costs are high.

According to the method disclosed in Patent Document 4, it is not possible to remove only the adductor muscles from shelled scallops that have been shelled. In addition, in the first half of the process, it is not easy to separate and aspirate only the internal organs from the lower shell without separating the adductor muscle adhering to the lower shell from the lower shell. It seems that it is not always possible.

Patent Literature 5 discloses a method of separating the shell from the inner surface of the shell, but this method cannot separate the adductor muscle and the internal organs.

In the method disclosed in Patent Document 6, it is necessary to set the shelled scallops one by one in the separation processing device. Since only the adductor muscle must be clamped with an appropriate pressure, the work is very complicated and inefficient. In addition, if the size of the adductor muscle and the disk holding the adductor muscle are not matched, the internal organs cannot be properly separated from the adductor muscle. In addition, since the internal organs separated by centrifugal force scatter around, it is thought that a contamination-prevention cover or the like is necessary. Furthermore, since high-speed rotation of 500 rpm or more is performed, a high-strength and high-performance rotation mechanism is required. Thus, the apparatus for carrying out the method disclosed in US Pat. No. 6,300,000 is complex and highly accurate.

Patent Documents 7 to 12 mainly disclose a method for separating the viscera string from the uro, but do not disclose a method for separating the viscera from the scallop adductor muscle.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1(A) is a plan view of a shell 1 of a scallop, which is an example of a mussel shell, and FIG. 1(B) is a schematic side view of its adductor muscle 1a. Although scallop shells 1 are described herein, the following description applies equally to shell shells of any mussel species other than scallops. The shelled meat 1 may be heat-treated. The stripped meat 1 consists of a substantially cylindrical scallop 1a, a mantle (also called string or ear) 1b positioned so as to wrap around the scallop 1a, and a midgut gland connected to a part of the string 1b ( 1c (also called uro) and other parts (gonad, heart, gills, etc.). For the sake of convenience, parts other than adductor muscle 1a are collectively referred to as visceral parts. Among the visceral parts, the part (mainly the string 1b) positioned at the outer peripheral edge of the shelled meat 1 is particularly referred to as the visceral peripheral part. In general, the adductor muscle 1a is mainly edible, and the internal organs are often not edible. Accordingly, fisheries processors take out the scallop 1a from the shelled 1 and process it. The present invention makes it possible to easily separate the internal organs of the shelled 1 and take out only the adductor muscle 1a.

FIG. 2 is a schematic cross-sectional view showing the main structure of the visceral portion separating device 2 for removing the visceral portions (string 1b, tail 1c, etc.) of the shelled meat 1 according to one embodiment of the present invention. FIG. 3(A) is an enlarged view showing the shape of the roller 4 of this device 2 in a plane orthogonal to the longitudinal direction of the roller 4, and FIG. It is an enlarged view. FIG. 4 is a plan view showing the main structure of this visceral part separating apparatus 2. As shown in FIG. This visceral part separating apparatus 2 has a processing platform 3 comprising a plurality of plates 3a, 3b and 3c. One surface of the processing table 3 is a surface on which the shelled meat 1 to be processed is placed. A cylindrical roller 4 is arranged on the other side of the processing table 3 . Further, another cylindrical roller 5 is arranged vertically below the roller 4 in the installed state of the viscera part separating device 2 . The roller 4 extends along the width direction W (see FIG. 4) of the processing table 3 and is rotatable around a rotation shaft 4a also provided along the width direction W. As shown in FIG.

An opening 6 is provided at a position of the processing table 3 facing a portion of the outer peripheral surface of the roller 4 . The opening 6 extends along the width direction W of the processing table 3, and the dimension S in the direction L perpendicular to the width direction W (see FIGS. 2 and 4) is larger than the diameter D of the roller 4 (see FIG. 2). It is shaped like a small slot (slit) (see Figures 2 and 4-6). The slot-shaped opening 6 of the present embodiment is formed by a gap provided between adjacent plates 3a and 3b among the plurality of plates that are arranged side by side in a plane and constitute the processing table 3 . The plate 3b includes a body plate portion 3b1, and an edge plate portion 3b2 that is attached to the tip of the body plate portion 3b1 and forms one end of the elongated opening 6 (end portion on the downstream side in the rotation direction A of the roller). consists of The edge plate portion 3b2 is attached to the main body plate portion 3b1 so as to be able to move forward and backward, and the edge plate portion 3b2 protrudes from the tip of the main body plate portion 3b1 toward the plate 3a, thereby narrowing the opening 6 and separating the plate 3b from the edge plate portion 3b2. The dimension E (see FIGS. 2 and 3A) of the gap 14 formed between the roller 4 and the outer peripheral surface can be increased. Reducing the amount of protrusion of the edge plate portion 3b2 from the tip of the main body plate portion 3b1 makes it possible to widen the opening 6 and reduce the dimension E of the gap 14 between the plate 3b and the outer peripheral surface of the roller 4. In the case of this configuration, the end of the edge plate portion 3b2 on the side of the plate 3a (the side of the opening 6) is the edge portion 3e that constitutes the end of the opening 6 on the downstream side in the rotation direction A of the roller 4. Thus, if the processing table 3 is composed of a plurality of plates 3a to 3c and the opening 6 is a gap between the adjacent plates 3a and 3b, then the plate (this In the embodiment, the dimension S of the opening 6 and the dimension E of the gap 14 can be easily adjusted by moving the edge plate portion 3b2). The plate 3b is supported by a spring 10, and the spring 10 is fixed via a spring holding member 12 and a bolt 13 to a frame 11 fixed to a housing (not shown). As will be described later, the spring 10 allows the plate 3b to rise to allow the internal organs to enter the gap 14 between the plate 3b and the outer peripheral surface of the roller 4 when the relatively thick internal organs (for example, the bottom 1c) enter the gap 14. At the same time, when the internal organs are removed from the gap 14 between the plate 3b and the outer peripheral surface of the roller 4, the position and posture of the plate 3b are returned to the original position and the gap 14 between the plate 3b and the outer peripheral surface of the roller 4. acts to keep constant. In addition, when a foreign object such as a shell or a pebble is carried to the opening 6 by mistake, the plate 3b is lifted by the action of the spring 10 to allow the foreign object to pass through, thereby preventing damage to the plate 3b. However, it is also possible to omit the spring 10 and its fixing mechanism (the spring holding member 12 and the bolt 13).

The vertical dimension E of the gap 14 between the plate 3b (edge portion 3e) and the outer peripheral surface of the roller 4 in the step of rotating the roller 4 for separating the internal organs in the installed state of the internal organs separating device 2 is smaller than the diagonal line T (see FIG. 1(B)) of the quadrangle that is the side shape of the adductor muscle 1a, and is preferably larger than the thickness of the string 1b that is the viscera peripheral portion. The adductor muscle 1a of the shellfish assumed to be processed by the partial viscera separating method and the partial viscera separating apparatus 2 of the present invention has a columnar shape, and the diagonal line T (see FIG. 1(B)) of the quadrangle which is the side shape thereof. The lower limit is approximately 30 mm, and the thickness of the string 1b, which is the peripheral portion of the internal organs, is approximately 1 to 5 mm. Therefore, the vertical dimension E of the gap 14 between the plate 3b (edge portion 3e) and the outer peripheral surface of the roller 4 is preferably 1 mm to 30 mm. The dimension of the opening 6 in the width direction W (see FIG. 4) of the processing table 3 is such that the gap 14 between the plate 3b and the outer peripheral surface of the roller 4 can be maintained at a constant dimension due to the bending of the plate 3b or the like. It is preferable to set the length to the extent that it is not difficult.

The rollers 4 are arranged on the surface (the other surface) opposite to the surface (one surface) on which the shelled meat 1 is placed on the processing table 3 , and a part of the rollers 4 is positioned within the opening 6 . Therefore, part of the outer peripheral surface of the roller 4 is exposed vertically upward through the opening 6 . The rollers 4 are rotatable around a rotating shaft 4 a provided along the width direction W of the processing table 3 . The longitudinal direction of roller 4, rotation axis 4a and opening 6 extend in parallel to each other. It is preferable that the dimension F in the width direction W of the processing table 3 of the portion where the roller 4 is exposed in the opening 6 is 100 mm or more. This is because if the dimension F in the width direction W of the portion where the rollers 4 are exposed in the opening 6 is too short, it will be difficult to process a large number of shelled meat 1 at the same time, resulting in low working efficiency. However, the dimension F in the width direction W of the processing table 3 may be less than 100 mm. In the examples shown in FIGS. 4 and 5, since the dimension of the opening 6 in the width direction W of the processing table 3 is larger than the dimension of the roller 4, the dimension F of the portion where the roller 4 is exposed in the opening 6 is It corresponds to the dimension of the roller 4 itself in the same direction.

As shown enlarged in FIGS. 3(A) and 3(B), on the outer peripheral surface of the roller 4, the internal organs (string 1b, tail 1c, etc.) of the shelled meat 1 placed on the processing table 3 are placed. A plurality of claw-like portions 7 protruding radially outward of the roller 4 from the outer peripheral surface are provided so as to be hookable. The claw-shaped portion 7 of this embodiment is a ridge extending along the longitudinal direction of the roller 4 . The roller 4 is exposed vertically upward through the opening 6 in a specific direction (direction A in FIGS. 2 and 3 (A)) when removing the internal organs of the shelled meat 1. The portion where the plate 3a rotates in the direction from the plate 3a toward the plate 3b. The shape of the claw-shaped portion 7 of the present embodiment on the surface perpendicular to the longitudinal direction of the roller 4 is such that the front side (downstream side) in the rotational direction (direction A) of the roller 4 is substantially vertical and the rear side (upstream side) is substantially vertical. ) is a triangular shape with an acute angle toward The height (height of the triangle) H of the claw-shaped portion 7 projecting radially from the outer peripheral surface of the roller 4 is preferably 30 mm or less. As described above, the vertical dimension E of the gap 14 between the plate 3b (edge portion 3e) and the outer peripheral surface of the roller 4 is 1 mm to 30 mm. Therefore, the minimum distance G (see FIG. 3A) between the plate 3b (edge portion 3e) and the tip of the claw-shaped portion 7 is greater than 0 mm and 29 mm or less (when the distance G is 0 mm, the roller 4 (It is not preferable because it becomes difficult to rotate smoothly). In the rotation direction (direction A) of the roller 4, the interval (pitch) P between the tips of the adjacent claw-shaped portions 7 is preferably 10 mm or less, more preferably 6 mm or less. As an example, this pitch P is 3 mm. Since the claw-like portions 7 have such a shape and the pitch P, the viscera portion of the shelled meat 1 can be easily caught by the rotation of the roller 4 in the A direction. The diameter D of the roller 4 (see FIG. 2) is preferably larger than the dimension S of the opening 6 in the direction L orthogonal to the width direction W of the processing table 3 (see FIGS. 2 and 4). For example, the roller 4 is made of metal such as stainless steel or aluminum so that the gap 14 between the roller 4 and the edge portion 3e does not change much due to wear or the like. In the examples shown in FIGS. 4 to 6, the claw-shaped portion 7 is formed as a ridge extending along the longitudinal direction of the roller 4, but the claw-shaped portion 7 is not limited to such a structure. Any structure can be used as long as it can hook the string 1b and the tail 1c. For example, a structure in which a plurality of claw-shaped portions 7 having a short length in the longitudinal direction of the roller 4 are arranged side by side at intervals along the longitudinal direction of the roller 4 may be used.

Another roller 5 arranged vertically below the roller 4 in the installed state of the viscera portion separation device 2 is provided along the width direction W of the processing table 3 when removing the viscera portion of the shelled meat 1. It is rotatable about the rotary shaft 5a in the opposite direction (direction B shown in FIG. 2) to the direction of rotation of the roller 4 (direction A). The diameter of the other rollers 5 is preferably the same as the diameter of the rollers 4 . A plurality of protrusions 8 are provided on the outer peripheral surface of the other roller 5 and extend over the entire length of the other roller 5 in the longitudinal direction of the other roller 5 and in a direction oblique to the rotation axis 5a. The shape of the protrusion 8 on the plane orthogonal to the rotation axis 5a is an isosceles triangle that is line-symmetrical about a straight line orthogonal to the outer peripheral surface of the other roller 5 . It is preferable that the height of the protrusion 8 protruding in the radial direction of the other roller 5 is 30 mm or less. The minimum distance between the tip of the claw-shaped portion 7 of the roller 4 and the tip of the protrusion 8 of the other roller 5 is preferably 5 mm or less, more preferably 0.1 mm or more and 3 mm. Below, it is more preferably 0.1 mm or more and less than 1 mm. By rotating the roller 4 and the other roller 5 in such a state that the claw-shaped portion 7 and the protrusion 8 are close to each other, the internal organs of the shelled meat 1 hooked on the claw-shaped portion 7 of the roller 4 (string 1b , etc.) can be transferred to the other roller 5 at the portion where the tip of the claw-shaped portion 7 and the tip of the protrusion 8 of the other roller 5 face each other. That is, it is possible to prevent the visceral portion of the roller 4 engaged with the pawl-shaped portion 7 from being continuously held on the outer peripheral surface of the roller 4 , thereby facilitating the transfer to another roller 5 . The other roller 5 drops the viscera delivered from the roller 4 downward in the vertical direction. With the protrusion 8 of the other roller 5 hooking the viscera, it rotates almost once, and the roller 4 and the viscera again fall. It is not preferable to move to close positions. Therefore, it may have a projection 8 with a simple shape that has a smaller effect of hooking the internal organs than the claw-like portion 7 shown in FIG. Since the protrusion 8 extends diagonally with respect to the longitudinal direction of the other roller 5 and the rotation axis 5a, compared to the case of extending parallel to the longitudinal direction of the other roller 5 and the rotation axis 5a, The internal organs delivered from the roller 4 are easily dropped vertically downward by their own weight along the protrusions 8 in accordance with the rotation of the other rollers 5 without being held between the adjacent protrusions 8.例文帳に追加As an example, the other roller 5 is made of a synthetic resin such as Teflon (registered trademark) so that the internal organs can be easily dropped without sticking. In the examples shown in FIGS. 4 to 6, the protrusion 8 is formed as a protrusion extending over the entire length of the other roller 5 in a direction oblique to the longitudinal direction of the other roller 5. However, the structure of the protrusion 8 is not limited to this, and any structure may be employed as long as the string 1b and the tail 1c of the shelled meat 1 can be easily transferred to and from the roller 4. For example, a structure may be employed in which a plurality of protrusions 8 having short diagonal lengths are continuously arranged side by side at intervals along the diagonal direction.

Further, the apparatus for separating internal organs 2 is provided with a jetting mechanism 9 for jetting water onto the processing table 3 on which the shelled meat 1 is placed. By jetting water from the injection mechanism 9 to the shelled meat 1, the shelled meat 1 can be pressed to move toward the gap 14 between the plate 3b and the outer peripheral surface of the roller 4.

A method for removing the viscera portion of the shelled meat 1 using the viscera portion separating apparatus 2 of the present embodiment shown in FIGS. 2 to 4 will be described. 5A to 5E are plan views showing the steps of the method in sequence. First, the roller 4 is rotated in one direction (direction A in FIGS. 2 and 3A), and the other roller 5 is rotated in the direction opposite to the roller 4 (direction B in FIG. 2). As shown in A), the pre-shelled meat 1 is placed on the plate 3a of the processing table 3. Then, water is jetted from the jetting mechanism 9 toward the shelled meat 1. - 特許庁A part of the rotating roller 4 is exposed vertically upward through an elongated opening 6 which is a gap between the plates 3 a and 3 b of the processing table 3 . Therefore, at least a portion of the shelled meat 1 contacts a portion of the outer peripheral surface of the roller 4 at the opening 6 . A plurality of claw-shaped portions 7 are provided on the outer peripheral surface of the roller 4 , and the claw-shaped portions 7 come into contact with the shelled meat 1 . The visceral part of the shelled meat 1, particularly the string 1b, is relatively soft, so that it is strongly hooked on the claw-like portion 7 on the outer peripheral surface of the roller 4.例文帳に追加Specifically, a part of the flexible string 1b enters between the claw-shaped portions 7 on the outer peripheral surface of the roller 4, so that the string 1b is attached to the claw-shaped portion 7 of the roller 4 as a result. It becomes a state of being strongly hooked. Since the roller 4 is rotating in the A direction, the string 1b hooked on the claw-shaped portion 7 is pulled in the A direction. On the other hand, since the adductor muscle 1a is not as flexible as the string 1b, it does not enter between the claw-shaped portions 7 on the outer peripheral surface of the roller 4 so much and is not hooked on the claw-shaped portions 7 very strongly.

The string 1b strongly hooked and pulled by the claw-shaped portion 7 is attached to the edge portion 3e of the plate 3b of the processing table 3 at the end portion of the slot-shaped opening portion 6 on the downstream side in the rotation direction A of the roller 4. It tries to pass through the gap 14 (see FIG. 2) between the roller 4 and the outer peripheral surface. On the other hand, adductor muscle 1 a having a dimension (diagonal line T shown in FIG. 1(B)) larger than dimension E of gap 14 cannot pass through gap 14 . As a result, the string 1b is separated from the adductor muscle 1a, passes through the gap 14, and is drawn vertically downward on the processing table 3 as the roller 4 rotates. On the other hand, the scallop 1a does not pass through the gap 14 and is held on the rotating roller 4. As shown in FIG.

Since the string 1b is positioned so as to wrap around the adductor muscle 1a, as shown in order in FIGS. The rotation direction (C direction, FIGS. 5(A) to 5(E ) by rotating counterclockwise), the string 1b is pulled away from the scallop 1a, and along with the rotation of the roller 4, the string 1b is pulled downward from the processing table 3 through the gap 14 between the plate 3b and the outer peripheral surface of the roller 4. Easy to pull in. By jetting water from the injection mechanism 9 toward the shelled meat 1, the shelled meat 1 is pressed so as to move toward the roller 4 exposed through the opening 6, and is easily hooked by the claw-shaped part 7.例文帳に追加be able to. In addition, the water jetted from the jetting mechanism 9 promotes the rotation of the shelled meat 1 in the C direction, making it easier to remove the string 1b. In particular, the shelled meat 1 can be further easily rotated in the C direction by applying the water jetted from the jetting mechanism 9 to a position deviated from the center of rotation of the shelled meat 1 (the position of the straight line R1).

In this embodiment, while rotating the roller 4 in the A direction (see FIGS. 2 and 3), the string 1b is strongly hooked on the claw-shaped portion 7, and the stripped meat 1 is shown in FIGS. is rotated in the direction C to separate the string 1b from the adductor muscle 1a and pull it downward in the vertical direction of the processing table 3 through the opening 6. Then, the internal organs such as the pelvis 1c connected to the string 1b are successively pulled away from the string 1b and then from the adductor muscle 1a, and are drawn downward in the vertical direction of the processing table 3 through the opening 6. - 特許庁Since the internal organs such as string 1b and tail 1c of the shelled meat 1 and the adductor muscle 1a are not so firmly connected, the internal organs are relatively easily separated from the adductor muscle 1a. The internal organs such as the string 1b and the tail 1c drawn vertically downward of the processing table 3 are sandwiched between the claw-shaped portion 7 of the rotating roller 4 and the protrusion 8 of the other roller 5 and crushed. , or moved further vertically downward by the rotation of another roller 5 . As a result, the internal organs are removed and only the adductor muscle 1a remains on the roller 4 and is taken out as shown in FIG. 5(E). Internal organs adhering to the outer peripheral surfaces of the roller 4 and other rollers 5 are washed away by the water jetted from the jetting mechanism 9 . However, it is also possible to omit the injection mechanism 9 and make a configuration that does not inject water. As described above, in the step of separating and removing internal organs such as string 1b and tail 1c from scallop 1a, the directions in which shelled meat 1 is rotated on roller 4 are shown in FIGS. It is not limited to the C direction, and may be the direction opposite to the C direction (clockwise direction in FIGS. 5(A) to 5(E)). The rotation of the shelled meat 1 in the direction C on the roller 4 may be one turn or more or one turn or less.

Further, as shown in FIG. 6(A), in the shelled meat 1, the internal organs such as the string 1b may be positioned on both sides of the adductor muscle 1a in the thickness direction (height direction). In that case, not only the shelled meat 1 is rotated on the roller 4 in the C direction (or the opposite direction), but also as shown in FIGS. Rotate the roller 4 around the parallel straight line R2 (see FIGS. 5(B) and 6(B)) in the direction of rotation (direction A) and in the direction of rotation (direction B) opposite to the direction of rotation (direction A) of the roller 4, and turn the shelled meat 1 inside out. is preferred. As a result, the internal organs such as the string 1b located on both sides in the thickness direction (height direction) of the adductor muscle 1a can be continuously and sequentially removed. The rotation of the shelled meat 1 on the rollers 4 in the B direction may be about a half rotation (rotation of 180°).

As described above, in the present embodiment, a portion of the rotating roller 4 having the claw-shaped portions 7 on the outer peripheral surface is brought into contact with the shelled meat 1 at the opening 6, so that the viscera portion is removed by the claw-shaped portions 7. (for example, string 1b). Then, by the rotation of the roller 4, only the viscera portion is passed through the gap 14 (see FIG. 2) between the edge portion 3e of the plate 3b of the processing table 3 and the outer peripheral surface of the roller 4, and is moved in the vertical direction of the processing table 3. pull downwards. The adductor muscle 1a does not pass through the gap 14, is separated from the internal organs, remains on the roller 4, and is not drawn vertically downward on the processing table 3. - 特許庁The easy removal of the internal organs from the shelled meat 1 in this way is mainly realized by the following two factors. One factor is that the gap 14 between the edge portion 3e and the outer peripheral surface of the roller 4 is large enough to allow passage of the cord 1b, which is the peripheral portion of the internal organs, but to prevent passage of the scallop 1a. That is, as described above, the dimension E of the gap 14 is smaller than the lower limit of the diagonal line T (see FIG. 1(B)) of the quadrangle that is the side shape of the columnar scallop 1a, greater than the thickness of 1b. The lower limit of the diagonal line T of the quadrangle, which is the side shape of the columnar scallop 1a of the shelled shellfish 1 assumed to be processed by the method for separating viscera from parts and the apparatus for separating viscera from parts 2 of the present invention, is approximately 30 mm. The thickness of the string 1b, which is the portion, is approximately 1 to 5 mm. Therefore, the vertical dimension E of the gap 14 is preferably 1 mm to 30 mm. As a result, only the visceral portion can be selectively passed through the gap 14 and easily separated from the adductor muscle 1a and removed.

Another factor is that in the internal organs part separating method and the internal organs part separating apparatus 2 of this embodiment, the internal organs part (especially the string 1b) to be removed and the adductor muscle 1a to be left are separated into claw-like portions due to the difference in flexibility between them. It is possible to distinguish between the part that is strongly hooked on the part 7 and the part that is not so strongly hooked. To explain this point, at the opening 6, both the internal organs such as the string 1b of the shelled meat 1 and the adductor muscle 1a come into contact with the outer peripheral surface of the roller 4. As shown in FIG. If neither the visceral portion nor the adductor muscle 1a moves with the rotation of the roller 4 and does not reach the gap 14 between the edge portion 3e of the plate 3b and the outer peripheral surface of the roller 4, the visceral portion is removed. It cannot be easily removed from 1a. Conversely, if both the internal organs and the adductor muscle 1a are evenly pulled by the rotation of the roller 4, the internal organs and the adductor muscle 1a try to move integrally and cannot pass through the gap 14 and either stop or partially ( In particular, adductor muscles 1a) can be damaged. Therefore, in this embodiment, the internal organs (especially the string 1b) are easily moved by the rotation of the roller 4, whereas the scallop 1a is not so easily moved by the rotation of the roller 4. A claw-like portion 7 is provided for hooking the internal organs. The adductor muscle 1a is formed of muscle tissue and has high shape retention, so it is less flexible than the string 1b. Utilizing the difference in flexibility between this built-in portion and the adductor muscle 1a, the flexible built-in portion (especially the string 1b) enters between the claw-shaped portions 7 and substantially becomes a claw of the roller 4. The scallop 1a, which is not flexible, hardly enters between the claw-shaped portions 7, and is not so strongly caught by the claw-shaped portion 7. can. As a result, the internal organs (especially the string 1b) strongly hooked on the claw-like portion 7 pass through the gap 14 and are drawn vertically below the roller 4 as the roller 4 rotates. On the other hand, the scallop 1a that is not so strongly hooked by the claw-like portion 7 does not pass through the gap 14 and remains on the roller 4 without being pulled by the claw-like portion 7 any more. Since the adductor muscle 1a remaining on the roller 4 is not so strongly hooked by the claw-shaped part 7, the roller 4 having the claw-shaped part 7 idles under the adductor muscle 1a and hardly damages the lower surface of the adductor muscle 1a. . In this way, by utilizing the difference in flexibility between the visceral part and the adductor muscle 1a, the visceral part can be removed and only the adductor muscle 1a can be easily taken out.

As described above, the flexible internal organs (particularly the string 1b) are likely to enter between the claw-shaped portions 7, and the non-flexible adductor muscle 1a is mostly between the claw-shaped portions 7. In order to prevent it from entering, as shown in FIG. 3A, a spacing (pitch) P between the tips of the claw-shaped portions 7 adjacent in the rotation direction (direction A) of the roller 4 is set. . The cross-sectional area of the space 15 (see FIG. 7) into which the internal organs (particularly the string 1b) enter is determined by the height H of the claw-shaped portion 7 and the interval P between the tips of the claw-shaped portions 7. As shown in FIG. If the cross-sectional area of this space 15 is too large, not only the string 1b but also the adductor muscle 1a will easily enter the space 15. When both the internal organs and the adductor muscle 1a enter the space 15 and are substantially hooked on the claw-shaped portion 7, as described above, both the internal organs and the adductor muscle 1a are evenly pulled by the rotation of the rollers 4, and the adductor muscle 1a is pulled. It is difficult to separate the internal organs from 1a, and adductor muscle 1a may be damaged. The general size of a scallop, which is a representative example of the mussel shells to be processed by the method for separating viscera and the apparatus for separating viscera 2 of the present invention, is the diagonal line T is 30 mm or more, and the thickness of the string 1b, which is the peripheral portion of the internal organs, is 1 mm to 5 mm), the distance P between the tips of the claw-shaped portions 7 is preferably 10 mm or less, more preferably 6 mm or less. On the other hand, if the interval P between the tips of the claw-shaped portions 7 is too small, it becomes difficult for the string 1b to enter the space 15, making it difficult to move the shelled meat 1 by the rollers 4 and separate the string 1b from the adductor muscle 1a. . Therefore, it is preferable that the interval P is 1 mm or more.

In order to strongly hook the internal organs (especially the string 1b) and not so strongly hook the adductor muscle 1a, as shown in FIGS. The claw-shaped portion 7 preferably has a triangular shape in which the downstream side (front side) in the rotation direction (A direction) of the roller 4 is substantially vertical and the upstream side (rear side) is at an acute angle. Moreover, it is preferable that the height H (the height of the triangle) of the claw-shaped portion 7 projecting radially from the outer peripheral surface of the roller 4 is 30 mm or less. As a result, as described above, the string 1b, which is a thin internal organ peripheral portion with a thickness of approximately 1 to 5 mm, is strongly hooked, and the length of the diagonal line T (see FIG. 1 (B)) of the side-shaped square is approximately 30 mm. It is possible to make a configuration in which the thick scallop 1a as described above is not caught too strongly. At this time, the minimum gap G (see FIG. 3A) between the edge portion 3e and the tip of the claw-shaped portion 7 of the roller 4 in the gap 14 is 6 mm or less.

In order to efficiently process a large number of shredded meats 1 using the entire roller 4 , the claw-like portions 7 extend substantially over the entire length of the roller 4 in parallel with the rotation axis 4 a of the roller 4 . preferable. The rotation speed of the roller 4 is preferably 200 revolutions per minute or less. If the rotational speed is too fast, the internal organs may not be caught by the pawl-shaped portion 7 and may not move smoothly as the roller 4 rotates.

The other roller 5 is made of synthetic resin, for example, and has a plurality of projections 8 on the outer peripheral surface of the other roller 5 . In order to smoothly transfer the internal organs from the roller 4 to the other roller 5, the diameter of the other roller 5 is approximately the same as the diameter of the roller 4, and the rotational speed of the other roller 5 is the same as the rotational speed of the roller 4. It is preferable to be about (200 revolutions per minute or less). However, when the diameter of the other roller 5 is smaller than the diameter of the roller 4, the rotational speed of the other roller 5 is made faster than the rotational speed of the roller 4, and the diameter of the other roller 5 is larger than the diameter of the roller 4. is also larger, the rotation speed of the other roller 5 is made slower than the rotation speed of the roller 4 . Further, in order to smoothly transfer the internal organs from the roller 4 to the other roller 5 , the height of the protrusion 8 radially protruding from the outer peripheral surface of the other roller 5 is 30 mm or less. The minimum distance between the tip of the portion 7 and the tip of the projection 8 of the other roller 5 is preferably 5 mm or less, more preferably 0.1 mm or more and 3 mm or less, and even more preferably 0.1 mm or more and less than 1 mm. Furthermore, it is preferable that the protrusion 8 is obliquely inclined with respect to the rotation shafts 4a and 5a and extends substantially over the entire length of the other roller 5. As shown in FIG. As a result, even if the internal organs transferred from the roller 4 to the other roller 5 enter between the adjacent protrusions 8, the water jetted from the jetting mechanism 9 and flowing vertically along the protrusions 8. It is easy to flow downward in the direction, and it can be suppressed that it is held on the outer peripheral surface of another roller 5 and sticks. However, it is also possible to adopt a configuration in which the other rollers 5 are omitted.

3A and 3B, the shape of the claw-shaped portion 7 of the embodiment shown in FIGS. is almost vertical and has a triangular shape with an acute angle toward the rear side (upstream side). According to the claw-like portion 7 having such a shape, the string 1b can be easily hooked while the roller 4 rotates in the A direction. However, the shape of the claw-shaped portion 7 is not limited to such a triangular shape, and may be an isosceles triangle, a trapezoid, a tapered square, a partially curved tapered approximate polygon, or the like.

For example, as shown in FIGS. 8A and 8B, the shape of the claw-shaped portion 7 on the surface orthogonal to the longitudinal direction of the roller 4 is symmetrical about a straight line orthogonal to the outer peripheral surface of the roller 4. It may be an isosceles triangle. According to this configuration, the string 1b can be caught by the claw-like portion 7 and rolled in, the structure is simple, and the roller 4 can be arranged regardless of the direction of rotation. As shown in FIGS. 9A and 9B, even if the shape of the claw-shaped portion 7 on the surface orthogonal to the longitudinal direction of the roller 4 is a triangle with a high height from the outer peripheral surface of the roller 4, good. According to this configuration, since the tip of the claw-shaped portion 7 is sharp, it is easily caught on the string 1b. However, it is preferable not to make the angle of the tip of the claw-shaped portion 7 too small so as not to excessively hook and damage the adductor muscle 1a. As shown in FIGS. 10A and 10B, the shape of the claw-shaped portion 7 on the surface perpendicular to the longitudinal direction of the roller 4 may be a trapezoid with a flat tip. According to this configuration, since the contact area between the claw-shaped portion 7 and the string 1b hooked by the claw-shaped portion 7 is large, the force to pinch the string 1b is strong, and the force to entwine the string 1b in accordance with the rotation of the roller 4 is also strong. In this case, the interval P between the adjacent flat ends of the adjacent claw-shaped portions 7 is preferably 1 mm or more and 10 mm or less, more preferably 1 mm or more and 6 mm or less, as described above. preferable. As shown in FIGS. 11(A) and 11(B), the shape of the claw-shaped portion 7 on the surface perpendicular to the longitudinal direction of the roller 4 is such that the tip thereof is curved and forward in the rotation direction (direction A) of the roller 4. It may be a modified triangular shape with a claw shape that points towards the side (downstream). According to this configuration, the string 1b can be hooked more easily. Thus, the shape of the claw-shaped portion 7 is not limited, and is determined in consideration of the viewpoint of strongly hooking the internal organs and the viewpoint of not damaging the adductor muscle 1a as much as possible.

Another embodiment of the gut part separating device 2 of the present invention is shown in FIG. In this embodiment, the processing table 3 is composed of two plates 3a and 3b. That is, the plate 3c of the embodiment shown in FIG. 2 is omitted. In addition, the plate 3b has a structure consisting of only one member instead of a two-plate structure consisting of the body plate portion 3b1 and the edge plate portion 3b2. In this configuration, the end of the plate 3b on the side of the plate 3a (the side of the opening 6) is the edge 3e that constitutes the end of the opening 6 on the downstream side in the rotation direction A of the roller 4. As shown in FIG. Further, in this embodiment, the springs 10 are not attached to the plate 3b, and accordingly the spring holding members 12 and the bolts 13 are also unnecessary. Since it is not necessary to provide the frame 11 with a flange-like portion for holding the spring, the frame 11 is not shown in FIG. Furthermore, in this embodiment, the injection mechanism 9 for injecting water is omitted. The internal organs may be separated without spraying water onto the shelled meat 1, or water may be sprayed onto the shelled meat 1 from a water facility or the like provided separately from the internal organs separating device 2. good. In this way, in the internal organs part separating device 2 of the present embodiment, the plate 3b is made of only one member, and the spring 10 and the members attached to the spring 10 (the spring holding member 12, the bolt 13, the flange-shaped frame 11) It has a simpler structure than the internal organs part separating device 2 shown in FIG.

In the internal organs partial separating apparatus 2 of the present invention, the processing table 3 may be configured by one plate (not shown). In that case, a through-hole is provided in a part of one plate, and this through-hole constitutes the elongated opening 6 . The roller 4 is arranged so that a part of the outer peripheral surface faces the elongated hole-shaped opening 6 formed by the through hole. The edge portion 3e is a portion of one plate constituting the processing table 3, which constitutes the end portion of the slot-shaped opening 6 formed by a through hole on the downstream side in the rotation direction A of the roller 4. As shown in FIG. According to this configuration, the work of assembling the partial viscera separating apparatus 2, especially the work of setting the processing table 3, is facilitated.

As described above, in the present invention, the configuration of the processing table 3, the necessity of installing the spring 10 and the members associated with the spring 10, the necessity of installing the injection mechanism 9, etc., are determined individually and appropriately. A visceral part separating device 2 can be configured.

According to the present invention, without using a complicated and expensive device such as an image processing device, the internal organs are separated and only the adductor muscle 1a is obtained by a very simple operation of rotating the roller 4 and successively inserting the shelled scallops 1. Easy to take out. And there is little risk of damaging the adductor muscle 1a. A large number of shelled meat 1 can be processed continuously, and the processing cost can be kept extremely low.
