Description

  The present invention relates to a sealing method, a shutter device, and a shutter piece for sealing an outer shell material when manufacturing a food product in which an appropriate inner material is wrapped in an outer shell material such as bread dough. More specifically, the inner material may be, for example, a vegetable fibrous material or a fibrous material such as meat muscles, or a shutter piece when closing a shutter piece that is a large food and provided in the shutter device. Ingredients that are difficult to cut and separate during the closing operation of the shutter piece (hereinafter referred to as materials that are difficult to cut or difficult to cut) are included. The present invention relates to a sealing method, a shutter device, and a shutter piece that can easily seal an outer skin material even when difficult sealing is difficult.

  For example, in the case of producing an encapsulated food in which an appropriate inner material is wrapped in a skin material such as bread dough, the following is generally performed as follows. That is, when manufacturing enveloped food, an outer skin material and an inner material are separately supplied to the outer skin material hopper and the inner material hopper provided in the enveloped food manufacturing apparatus. Then, when the inner material and the outer skin material are fed from the respective hoppers to the polymerization nozzle in the encapsulated food manufacturing apparatus, the rod-shaped food material in the state surrounding the inner material with the outer skin material is discharged downward.

  As described above, when the rod-shaped food material is discharged from the polymerization nozzle, the food material is encapsulated and cut by a shutter device that can be moved up and down and opened and closed below the polymerization nozzle, The encapsulated food is produced.

  Moreover, when manufacturing a covering food, it may carry out as follows. That is, for example, as shown in Japanese Patent No. 4276800, a disk-shaped outer covering material is placed on a support plate having a vertical hole so as to cover the hole. And an inner material is supplied on the said outer skin material, and an outer skin material is recessed in the said hole so that this inner material may be wrapped. Then, the foodstuffs to be encapsulated are manufactured by converging and sealing the peripheral edge of the outer skin material on the support plate with an openable / closable shutter device.

  Further, as shown in, for example, Japanese Patent No. 2518764, a filling is supplied on a sheet fabric that is horizontally conveyed by a conveyor belt, the sheet fabric is wound up from one side, and the rod is wrapped around the filling. Manufacturing food ingredients. And this rod-shaped food material is covered and cut by a shutter device. In addition, when a rod-shaped food material is encapsulated and cut by a shutter device, as shown in Japanese Patent No. 2518764, when a food material is bent vertically or as shown in Japanese Patent No. 3512721, In some cases, the food material is horizontally cut and encapsulated.

  Furthermore, as a configuration of the shutter device, for example, a shutter device having a configuration as shown in the above-mentioned Japanese Patent No. 4276800, Japanese Patent No. 2518764, and Japanese Patent No. 3512721, for example, Japanese Patent No. 3009140, There are various types of shutter devices such as a shutter device configured as shown in Japanese Patent No. 5281276.

  That is, there are various manufacturing methods for manufacturing the encapsulated food, and there are shutter devices with various configurations in the shutter device.

  By the way, in the inner material, for example, a fibrous material such as vegetable or a fibrous material such as flesh, or a material that is difficult to cut (hardly-cut material) such as a material that is easily crushed when the shutter device is closed. When the hard-to-cut material is included and is located at a position corresponding to the sealing portion of the outer skin material, the outer skin material may not be sealed smoothly. Therefore, it has been proposed that the shutter piece in the shutter device is provided with a cutter blade to cut the hard-to-cut material (for example, see Patent Document 1).

Japanese Utility Model Publication No. 5-29394

  In the configuration described in Patent Document 1, when cutting the food material in the shutter opening surrounded by the plurality of shutter pieces in the shutter device, the cutter blade provided in one shutter piece is disposed in the shutter opening. The state is always protruding. Therefore, when the shutter opening is reduced and each shutter piece comes into contact with the outer peripheral surface of the food material, the cutting of the outer skin material by the cutter blade is started. That is, for example, it becomes a mode in which cutting of the outer skin material is started before the inner material is tightly compressed so that the outer skin material is bundled, and the inner material is likely to leak from the sealing portion of the outer skin material. There is.

  The present invention has been made in view of the problems as described above, and is a method for sealing food encapsulated by wrapping an inner material with an outer skin material, and gradually shrinks a shutter opening surrounded by a plurality of shutter pieces, When sealing the outer skin material in a state of wrapping the inner material with the outer skin material located in the shutter opening, a cutter provided in an appropriate shutter piece protrudes into the shutter opening to cut at least the inner material Then, the shutter opening is further reduced to seal the outer skin material.

  In the method for sealing encapsulated food, the cutter is provided in a plurality of shutter pieces, and each cutter intersects the opening axis of the shutter opening at the center position of the shutter opening. The inner material is cut by moving in the direction.

  In the method for sealing encapsulated food, the inner material is cut when the diameter of the inner material becomes equal to or less than the width of the cutter.

  In the method for sealing encapsulated food, the cutting of the inner material by the cutter is performed in a state where tension is applied to the inner material.

  In addition, the shutter device performs sealing of the encapsulated food wrapped with the inner material by the outer skin material, and the outer skin is encased with the outer skin material positioned in the shutter opening surrounded by the plurality of shutter pieces. An appropriate shutter piece is provided with a cutter that can project into the shutter opening in order to cut the inner material when sealing the material.

  Further, in the shutter device, the cutter is provided in a plurality of shutter pieces arranged apart from each other.

  Further, the shutter piece forms a shutter opening that can be opened and closed by a plurality of shutter pieces, and includes a cutter that can be raised and lowered with respect to a shutter opening forming surface that forms the shutter opening. .

  The shutter piece further includes an actuator for projecting and retracting the cutter with respect to the shutter opening forming surface.

  Further, in the shutter piece, the cutter is provided so as to be able to protrude and retract on one end side of the shutter opening forming surface of the shutter piece.

  Further, the shutter piece is provided with a ridge portion formed with an inclined surface on the shutter opening forming surface in the shutter piece, and the cutter is provided on one end side of the ridge portion. It is.

  According to the present invention, when the shutter opening surrounded by the plurality of shutter pieces is gradually reduced, the outer skin material in the shutter opening is reduced in diameter, and the outer skin material is bound to a desired small diameter by the plurality of shutter pieces. In addition, the inner material can be cut by projecting the cutter into the shutter opening. Therefore, the outer skin material can be gathered (closed) near the cutting portion by the cutter, and the outer skin material can be reliably sealed.

  Hereinafter, a shutter device according to an embodiment of the present invention will be described with reference to the drawings. A packaged food manufacturing apparatus for manufacturing a packaged food having a configuration in which an inner material is wrapped with a skin material has various configurations. is there. Further, in various types of encapsulated food manufacturing apparatuses, there are various types of shutter devices for sealing the outer skin material in a state where the inner material is wrapped. The overall configuration of various types of encapsulated food manufacturing apparatuses is a well-known configuration, and the overall configuration of various types of shutter devices is also a well-known configuration. Therefore, description of the overall configuration of the encapsulated food manufacturing apparatus is omitted, and detailed description of the overall configuration of the shutter device is omitted.

  Referring to FIG. 1, a shutter device 1 according to an embodiment of the present invention is provided in a shutter frame 3 in an encapsulated food manufacturing apparatus (not shown). As is well known, the enveloping food manufacturing apparatus includes a superposition nozzle (not shown) for discharging a bar-shaped food material 9 surrounding the inner material 7 with the outer skin material 5 downward. And in order to produce the encapsulated food (not shown) in a state in which the food material 9 is encapsulated and cut and the inner material 7 is encapsulated by the outer skin material 5, the shutter device 1 is provided below the superposition nozzle. It is provided at the position so as to be movable up and down.

  The shutter device 1 includes a plurality of shutter pieces 13 that can freely open and close a regular polygonal shutter opening 11. The shutter device 1 includes a plurality of shutter shafts 15 that are rotatably supported by the shutter frame 3. The shutter shafts 15 are arranged at equal intervals on the same circle. Each of the shutter shafts 15 has a swinging portion 15A that is slidably engaged with a slot 17 provided in each of the shutter pieces 13 in a direction that is perpendicular to the shutter shaft 15 and is integrally formed. Is provided. Therefore, when the shutter shafts 15 are reciprocally rotated through an appropriate interlocking mechanism, the shutter pieces 13 are integrally reciprocated horizontally through the swinging portion 15A.

  Each shutter piece 13 includes a shutter opening forming surface 19 that forms the shutter opening 11, and a sliding contact surface 21 that is slidably slidably contacted with the shutter opening forming surface 19 of the adjacent shutter piece 13. I have. That is, the shutter pieces 13 are slidably joined to the shutter opening forming surfaces 19 of the adjacent shutter pieces 13 so that the shutter pieces 13 are connected to each other. There is a relationship that restricts the opening and closing operation. In other words, each shutter piece 13 is configured to perform an opening / closing operation in conjunction with each other.

  In the above configuration, when a control motor (not shown) is driven to rotate the appropriate shutter shaft 15 in the clockwise direction in FIG. 1A, each shutter shaft 15 is appropriately interlocked such as a gear mechanism. It is simultaneously rotated in the same direction via a mechanism (not shown). Accordingly, each shutter piece 13 is rotated in the clockwise direction in FIG. 1A, and the shutter pieces 13 are in a state of being bound to each other, so that the swinging portion 15A provided in each shutter shaft 15 is provided. Move along. That is, the shutter opening 11 surrounded by the shutter opening forming surface 19 of each shutter piece 13 is gradually reduced.

  Therefore, the peripheral surface of the rod-shaped food material 9 located in the shutter opening 11 is pressed toward the center by the shutter opening forming surface 19 in each shutter piece 13, and the outer skin material 5 and the inner material 7 of the food material 9 are gradually moved. It will be tied to a small diameter. And finally, by enclosing the constricted portion of the outer skin material 5, an encapsulated food (not shown in FIG. 1) in which the inner material 7 is wrapped with the outer skin material 5 is formed. It will be.

  By the way, at least one of the outer skin material 5 or the inner material 7 (in the present embodiment, the inner material 7), as shown in FIG. Foods that are difficult to cut when the shutter pieces 13 are closed (hereinafter referred to as difficult-to-cut materials) 23, such as foodstuffs and large-sized foodstuffs that are crushed when the shutter pieces 13 are closed. As described above, when the outer skin material 5 is sealed, the sealing may not be performed satisfactorily. Therefore, in the present embodiment, the appropriate shutter piece 13 is provided with cutters 25 and 27 for cutting the hard-to-cut material 23. As already understood, the cutters 25 and 27 may have only a function of cutting the difficult-to-cut material 23, and may be one. However, in this embodiment, the cutters 25 and 27 are individually provided in the plurality of shutter pieces 13.

  More specifically, each shutter piece 13 is formed in a thick plate shape having a horizontal upper surface and a lower surface. The shutter opening forming surface 19 of each shutter piece 13 has a vertical pressing surface 29 formed over the entire length, and protrudes from the pressing surface 29 at a substantially intermediate position in the vertical direction of the pressing surface 29. The protrusion 31 is formed horizontally over the entire length of the pressing surface 29. The protrusion 31 is provided in a state of protruding from the pressing surface 29 by forming upper and lower inclined surfaces 33U, 33L having opposite inclination directions over the entire length of the pressing surface 29. . In the upper and lower inclined surfaces 33U and 33L, the amount of inclination of the upper inclined surface 33U is formed larger than the amount of inclination of the lower inclined surface 33L. In other words, the pressing surface 29 is formed in a step difference between the upper side and the lower side of the protrusion 31, and as shown in FIG. 2B, the shutter opening 11 is lower on the lower side than on the upper side. It is the form which protruded inward slightly.

  An upper inclined surface 35 in the form of chamfering the intersection between the pressing surface 29 and the upper surface is formed over the entire length of the upper surface of the pressing surface 29 in each shutter piece 13. In addition, a lower inclined surface 37 having a direction opposite to that of the upper inclined surface 35 is formed at the lower portion of the pressing surface 29, and a lower pressing surface is formed on the lower portion of the lower inclined surface 37. A surface 39 is formed.

  The cutters 25 and 27 are provided on a plurality of shutter pieces 13 that are spaced apart from each other. In the configuration shown in FIG. 1, cutters 25 and 27 are provided on the shutter pieces 13 facing each other. The cutters 25 and 27 provided in each shutter piece 13 are arranged at a substantially central portion in the thickness direction of the shutter piece 13. More specifically, on the sliding contact surface 21 of each shutter piece 13 provided with the cutters 25 and 27, a cutter housing groove 41 in which the cutters 25 and 27 are reciprocally moved is provided on the sliding contact surface 21 over the entire length. It is formed.

  The position of the cutter accommodating groove 41 is substantially the center in the thickness direction of each shutter piece 13 and is a position corresponding to the protrusion 31. That is, the cutter accommodating groove 41 is opened on the shutter opening forming surface 19 side between the upper and lower inclined surfaces 33U and 33L of the protrusion 31. Therefore, each cutter 25, 27 provided in each shutter piece 13 is guided to the shutter opening forming surface 19 in the separate shutter piece 13 adjacent to the shutter piece 13, and one end of the ridge portion 31 in the shutter piece 13. From the opening of the cutter housing groove 41 on the side, it can protrude into the shutter opening 11. In other words, when the shutter opening 11 is contracted, the cutters 25 and 27 appear on one end side of the shutter opening forming surface 19 on the side where the shutter opening 11 is reduced so as to protrude into the contracted shutter opening 11. It is provided freely.

  In order to project the cutters 25 and 27 from the cutter housing grooves 41 in the shutter pieces 13 provided with the cutters 25 and 27 into the shutter opening 11, brackets 43 are integrally formed on the shutter pieces 13. Is provided. The bracket 43 is provided with an actuator 45 for projecting and retracting the cutters 25 and 27 with respect to the shutter opening forming surface 19 of the shutter piece 13. The actuator 45 is composed of a fluid pressure cylinder such as an air cylinder. A reciprocating operation rod 47 such as a piston rod provided in the actuator 45 so as to reciprocate is connected to the cutters 25 and 27. It is.

  Therefore, by operating the actuator 45, the cutters 25 and 27 are projected and retracted with respect to the shutter opening forming surface 19 of the shutter piece 13.

  Note that the cutters 25 and 27 only have a function of cutting the difficult-to-cut material 23 included in the food material 9 when the shutter opening 11 is reduced and the food material 9 is encapsulated. is there. Therefore, it is also possible to form the blades of the cutters 25 and 27 sharply and to cut the difficult-to-cut material 23 by intersecting the blade edges. In addition, the cutting edge of one cutter 25 is sharply formed, the cutting edge of the other cutter 27 is formed in a V-groove shape or a flat shape, and the cutting material 23 of the other cutter 27 is formed with the cutting edge of one cutter 25. It is also possible to adopt a configuration in which the blade is pressed against the cutting edge (a configuration in which push cutting is performed). That is, the cutting edges of the cutters 25 and 27 can adopt various forms.

  In the present embodiment, the cutting edge 49 of one cutter 25 is inclined with respect to the reciprocating direction of the cutter 25 as shown in FIG. It is. As shown in FIG. 1A, the inclination direction of the blade edge 49 is such that the outer edge side of the blade edge 49 on the sliding contact surface 21 side of the blade piece 49 when the cutter 25 protrudes into the shutter opening 11 is greater. Is also inclined so that the inner end is leading.

  The cutting edge 51 of the other cutter 27 is formed on a vertical plane facing the cutting edge 49 of the one cutter 25, and is inclined with respect to the reciprocating direction of the other cutter 27. The inclination direction of the blade edge 51 in the other cutter 27 is such that the outer end side of the blade edge 51 on the sliding contact surface 21 side of the shutter piece 13 provided with the cutter 27 projects into the shutter opening 11 later than the inner end side. It is so inclined.

  In the configuration as described above, as shown in FIG. 1A, when the shutter-shaped food material 9 is discharged downward from the polymerization nozzle in the enveloped food manufacturing apparatus when the shutter opening 11 is in a wide open state, The food material 9 passes through the central portion of the shutter opening 11. The food material 9 is supported by a support member 53 (see FIG. 1B) such as a transport belt provided at a position below the shutter device 1 so as to be movable up and down. Thereafter, the shutter device 1 and the support member 53 are lowered at the same speed as the lowering speed of the food material 9.

  When the shutter shaft 15 is rotated while the shutter device 1 is lowered and each shutter piece 13 is rotated (swinged) and closed, the shutter opening 11 surrounded by each shutter piece 13 is gradually reduced ( (Reduced diameter). As described above, when the shutter opening 11 is gradually reduced, the protrusion 31 provided on the shutter opening forming surface 19 of each shutter piece 13 comes into contact with the outer skin material 5 of the food material 9, and the outer skin material 5 Press inward to reduce the diameter. Therefore, the portion where the outer skin material 5 is pressed inward by the ridge portion 31 is gradually narrowed to a small diameter.

  At this time, since the upper and lower inclined surfaces 33U and 33L are formed on the ridge portion 31, a part of the portion where the outer skin material 5 is pressed inward by the ridge portion 31 is bound to the inclined portion 31. It will be induced | guided | derived to the up-down direction by the surfaces 33U and 33L, and the tension | tensile_strength of an up-down direction will be provided. Moreover, in the inner material 7 in the outer skin material 5, the part corresponding to the said protrusion part 31 will also be gradually tied the inner material 7 corresponding to the outer skin material 5 being gradually tied as mentioned above. (See FIG. 2B).

  Accordingly, the inner material 7 is guided in the vertical direction and gradually bundled at the portion corresponding to the protruding portion 31 in the same manner as the outer skin material 5. Therefore, the inner material 7 is given a tension that divides the inner material 7 up and down. That is, tension is applied to the inner material 7 corresponding to the protruding portion 31 and the difficult-to-cut material 23 in the inner material 7.

  Thereafter, when the shutter opening 11 is further reduced, the diameter of the inscribed circle inscribed in the shutter opening 11 becomes substantially equal to the width dimension of the cutters 25 and 27. Therefore, the outer skin material 5 in the food material 9 is narrowly bound to a thickness substantially equal to the width of the cutters 25 and 27 in the portion of the protrusion 31 in each shutter piece 13. As described above, when the outer diameter of the outer skin material 5 becomes substantially equal to the width dimension of the cutters 25 and 27, the actuator 45 is operated to project the cutters 25 and 27 into the shutter opening 11. The cutting edges 49 and 51 of 25 and 27 come into contact with each other at the center position of the shutter opening 11, that is, the opening axial position of the shutter opening 11 (see FIG. 3). Therefore, the difficult-to-cut material 23 contained in the inner material 7 at the constricted portion of the food material 9 is sandwiched between the cutters 25 and 27. Or it will be cut off.

  By the way, the timing for projecting the cutters 25 and 27 into the shutter opening 11 is not based on the timing described above, but when the diameter of the inner material 7 in the food material 9 is substantially equal to the width of the cutters 25 and 27. Is also possible. That is, when the difficult-to-cut material 23 is included only in the inner material 7, the difficult-to-cut material 23 can be cut even when the timing at which the cutters 25 and 27 protrude into the shutter opening 11 is set as described above. is there. At this time, a part of the outer skin material 5 is not cut by the cutters 25 and 27 and is in a state of being continuous up and down.

  As described above, after the blade edges 49 and 51 of the cutters 25 and 27 come into contact with each other, the pressing force of the cutters 25 and 27 by the actuators 45 is held at a predetermined pressing force, so that the shutter opening 11 is further reduced. When each shutter piece 13 is further rotated in the same direction, the cutters 25 and 27 maintain the state in which the blade edges 49 and 51 are in contact with each other and cross each other in the opposite direction, that is, the opening axis of the shutter opening 11. The cutting edges 49 and 51 of the cutters 25 and 27 move so as to be shifted in the width direction of the cutters 25 and 27 (see FIG. 4A). Therefore, the hard-to-cut material 23 that is sandwiched between the blade edges 49 and 51 of the cutters 25 and 27 and is in an uncut state is cut into pieces by rubbing.

  At this time, since the inner material 7 and the hard-to-cut material 23 in the inner material 7 are in a state where a vertical tension is applied, the hard-to-cut material 23 can be effectively cut.

  Further, as described above, after the cutting edges 49 and 51 of the cutters 25 and 27 come into contact with each other and the difficult-to-cut material 23 is cut, the outer skin material 5 and the inner material 7 in the food material 9 are moved up and down by the cutters 25 and 27. It is in a state of being cut and divided (see FIG. 3B). Therefore, when the shutter pieces 13 are rotated to further reduce the shutter opening 11 after the blade edges 49 and 51 of the cutters 25 and 27 are brought into contact with each other, the upper and lower inclined surfaces of the protrusions 31 in the shutter pieces 13. The outer skin material 5 and the inner material 7 cut and divided in the vertical direction are guided in the vertical direction by 33U and 33L (see FIG. 4B).

  And the lower end part of the outer skin material 5 in the food material 9 cut and divided on the upper side is sealed so as to be twisted by the upper pressing surface 29 in each shutter piece 13. That is, a downward projecting portion 55 (see FIG. 4B) that is sealed (bound) so that the outer skin material 5 is twisted is temporarily formed at the lower end portion of the food material 9 cut and divided on the upper side. Is done. A part of the inner material 7 located at a portion corresponding to the downward projecting portion 55 is gradually returned (squeezed out) when the downward projecting portion 55 is gradually formed.

  Further, the upper end portion of the outer skin material 5 in the food material 9 cut and divided on the lower side is sealed so as to be twisted by the lower pressing surface 29 and the lower pressing surface 39 of each shutter piece 13. In other words, an upward protruding portion 57 (see FIG. 4B) that is sealed so that the outer skin material 5 is twisted is temporarily formed on the upper end portion of the food material 9 cut and divided on the lower side. A part of the inner material 7 positioned at a portion corresponding to the upward protrusion 57 is squeezed downward when the upward protrusion 57 is gradually formed to be thin.

  By the way, in each shutter piece 13, a lower pressing surface 29 and a lower pressing surface 39 are formed in steps on the lower side of the protrusion 31 on the shutter opening forming surface 19. Therefore, when the upward protrusion 57 is formed as described above, the diameter of the upper portion where the upward protrusion 57 is formed by the lower pressing surface 29 is the lower portion formed by the lower pressing surface 39. It is formed with a smaller diameter than the diameter. Therefore, the upper part is pressed and sealed (bound) more strongly than the lower part. In other words, the upward projecting portion 57 performs sealing at two locations, the upper portion and the lower portion, and the upper portion is more firmly sealed.

  As described above, the food material 9 is cut and separated in the vertical direction, the downward projecting portion 55 is formed at the lower end of the food material 9 cut and separated on the upper side, and the upper end of the food material 9 cut and separated on the lower side. After the upward protrusions 57 are formed on the shutter pieces 13, if the rotation of the shutter pieces 13 in the same direction is continued, the upper and lower surfaces of the shutter pieces 13 become horizontal surfaces even at the center position of the shutter opening 11, and the lower The direction protrusion 55 is immersed in the upper food material 9. And the upward protrusion 57 is immersed in the lower food material 9 (refer FIG. 5). This lower food material 9 is in a state of wrapping the inner material 7 with the outer skin material 5 and constitutes the food to be encapsulated.

  By the way, as shown in FIG. 3A, when the blade edges 49 and 51 of the cutters 25 and 27 protrude into the shutter opening 11 and are held in contact with each other, the shutter opening 11 is reduced. 4A, the blade edges 49 and 51 of the cutters 25 and 27 move to the sliding contact surface 21 side of the adjacent shutter piece 13, so that the cutting edges 49 and 51 of the respective cutter pieces 13 move to the sliding contact surface 21 side. Is formed with a clearance groove 21G for avoiding interference with the blade edges 49, 51.

  Therefore, there is no problem even if the blades 49 and 51 of the cutters 25 and 27 are held in a state of protruding to the shutter opening 11 and the shutter opening 11 is reduced.

  In the above description, even when the hard-to-cut material 23 is cut by the cutters 25 and 27, the case where the encapsulated food is manufactured by holding the cutters 25 and 27 in a state of protruding into the shutter opening 11 has been described. However, after cutting the hard-to-cut material 23, the actuator 45 can be operated to return the cutters 25 and 27 to their original positions at a desired timing.

  Moreover, in the said description, the case where the shutter piece 13 was made into six and the shutter opening 11 was formed in the regular hexagon was illustrated. However, it is also possible to form the shutter opening 11 in a desired regular polygon by changing the number of shutter pieces 13. For example, when five shutter pieces 13 are used, the shutter opening 11 has a regular pentagon as schematically shown in FIGS. The cutters 25 and 27 are provided in the shutter piece 13 that is arranged adjacent to each other without being adjacent to each other. The cutting edges 49 and 51 of the cutters 25 and 27 are formed so that the cutting edges 49 and 51 come into contact with each other at the center position of the shutter opening 11.

  Also in the above configuration, since the cutters 25 and 27 are provided in the shutter opening 11 so as to be able to appear and retract, the food material 9 to be encapsulated and cut includes the difficult-to-cut material 23. It can be cut by the cutters 25 and 27, and can achieve the same effects as the above-described configuration.

  As already understood, according to the present embodiment, even if the inner material of the food material 9 includes the hard-to-cut material 23 that is difficult to cut, the cutters 25 and 27 provided in the shutter piece 13 are used. The hard-to-cut material 23 is cut. Therefore, even when the hard-to-cut material 23 is included in the outer skin material of the food material 9, the food material 9 can be cut and encapsulated to easily produce the encapsulated food. Even when only the food material similar to the inner material or the outer skin material including the hard-to-cut material 23, that is, the single dough including the hard-to-cut material 23 is supplied to the shutter opening 11 and cut, the food is divided. Can be easily performed.

  In the above description, the case where the food material 9 has a rod shape has been described. However, it is also possible to apply the present invention to a shutter device in the case of manufacturing a food product by wrapping an inner material with a disc-shaped outer skin material.
