Description

The present invention relates to a manufacturing apparatus and a manufacturing method for manufacturing encapsulated foods by supplying fruits such as strawberries and chestnuts or solids such as boiled eggs into confectionery such as buns and cooked foods such as hamburgers. More specifically, the present invention relates to a manufacturing apparatus and a manufacturing method for manufacturing an encapsulated food containing two or more solid substances.

A traditional Chinese confectionery has a moon cake containing two yokes. York is a solid product of salted duck egg yellow. As for the double egg yolk moon cake, what was embossed by the disk shape and a rectangular parallelepiped (bottom surface is a square) is common. In this moon cake, it is desirable that the two yokes are located at an equal distance from the center of the moon cake.

Patent Document 1 describes a wrapping machine as a manufacturing apparatus for manufacturing a food product including two solid substances. This wrapping machine includes a superposition nozzle in which an outer cylinder, an inner cylinder, and a central cylinder are concentrically formed. A solid material supply device is provided on the top of the polymerization nozzle. In addition, a covering and cutting device is provided below the superposition nozzle. Further, a belt conveyor as a conveying device is provided below the covering and cutting device. A stamping machine for stamping the food to be encapsulated is provided on the downstream side of the transport device.

This solid material supply apparatus is rotatably provided with a turntable in which accommodation holes for accommodating two solid materials as a set are formed at predetermined intervals. From this solid material supply device, two solid materials form a set and are intermittently supplied to the central tube of the polymerization nozzle. And the stick-shaped foodstuff of the three-layer structure which consists of a solid substance, the inner material which covers a solid substance, and the outer skin | cover material which covers an inner material is discharged from a superposition | polymerization nozzle. Furthermore, the encapsulated food containing the two solids is cut from the rod-shaped food by the enveloping / cutting device. At this time, the two solids are in close contact with each other in the up-down direction inside the encased food.

And this covering food is replaced by a hand etc. so that the said up-down direction may face a conveyance direction (horizontal direction). Thereafter, the encapsulated food is stamped by the stamping machine. At this time, manual work or the like is necessary to adjust the direction of the food to be encapsulated, and improvement in production efficiency has been desired. Moreover, since the two solids in the encapsulated food are crushed by the mold from the state where the solids are in close contact with each other, the solids may not be separated from each other. Further, even when solids are separated from each other, there is a problem that the distance between the solids is not stable because the degree of adhesion between the solids is not constant. In addition, since a void is formed between the two solids, the encapsulated food bursts during baking (the internal air expands due to heating and breaks the encapsulated food). . In particular, when the encapsulated food is a two-grain protein yellow moon cake, there is a problem that the commercial value thereof is remarkably lowered. Therefore, there is only a method for manufacturing the original two-yen yolk moon cake manually, and a manufacturing apparatus and a manufacturing method capable of improving the production efficiency have been desired.

Here, the covering cutting process based on the first embodiment of the present invention will be described. The encapsulated food here is a two-grain protein moon cake using moon cake dough for the outer skin, rice cake for the inner packaging material, and yoke for the solid material.

A description will be given from a state in which the inner packaging material 5 and the outer skin material 9 are discharged from below the polymerization nozzle 13. The rod-shaped fabric 19 is discharged from the discharge port 47A of the outer cover material nozzle 47. The rod-shaped fabric 19 has a double structure in which the inner packaging material 5 is covered with the outer skin material 7. The inner packaging material 5 passes between the inner circumferential surface of the inner packaging material nozzle 45 and the outer circumferential surfaces of the two pipe members 41A and 41B of the introduction guide 37 and is discharged from the discharge port 45A of the inner packaging material nozzle 45. The At this time, bag-like spaces 5A and 5B having two cylindrical shapes and bottom portions are formed inside the inner packaging material 5 discharged in a rod shape.

At this time, the rotating disk 65 of the solid supply device 57 rotates 15 degrees in the direction of arrow T and stops again. Then, the solids A and B are simultaneously dropped from the receiving holes 65A and 65B of the rotary disk 65, and are individually supplied to the spaces 5A and 5B of the inner packaging material 5, respectively. Further, simultaneously with the stop of the rotary disk 65, the rodless cylinder of the push-in device 71 is driven, and the pistons 78A and 78B stopped at the raised position are respectively accommodated in the receiving holes 65A and 65B and the passages (penetrations) of the introduction guide 37. The inside of the hole 39A and the pipe member 41A, the through hole 39B, and the pipe member 41B) is lowered. At this time, when the solid matter stays in the passage, the pistons 78A and 78B can push the solid matter A and B down to the lowered position, and the solid matter A and B are put into the bag-like spaces 5A and 5B. It can be supplied stably. Further, since the pistons 78A, 78B press the solids A, B against the bottoms of the bag-shaped spaces 5A, 5B, the lower portions of the solids A, B can be brought into close contact with the inner packaging material 5. In addition, since the inner packaging material 5 is interposed between the two solid materials A and B, the solid materials A and B can be arranged apart from each other in the horizontal direction without being in contact with each other inside the bar-shaped dough 19. it can.

The pistons 78A and 78B lowered to the lowered position are again raised. Before or after the pistons 78A and 78B are raised or raised, the suction device is operated to suck air in the spaces 5A and 5B of the inner packaging material 5 from the tips of the hollow pistons 78A and 78B. The wrapping / cutting device 21 is operated in conjunction with this suction operation, and the package includes two solids A and B contained in the horizontal direction from the triple-structured rod-like food 19 containing the solids A and B. The foodstuff 23 is manufactured. At this time, the pressure in the bag-like spaces 5A and 5B containing the solids A and B is reduced, and the spaces 5A and 5B are reduced. Accordingly, since the inner packaging material 5 moves so as to be in close contact with the solids A and B, it is possible to suppress the formation of a gap around the solids A and B, and heat treatment such as firing. It is possible to prevent the encapsulated food from bursting during the process (internal air expands due to heating and breaks the encapsulated food). In this description, the positions of the lower ends of the pipe members 41A and 41B are the same as the positions of the lower ends of the outer cover material nozzle 47. However, the position of the lower ends of the pipe members 41A and 41B is not limited to this. It is also possible to position it below the lower end position of the outer skin material nozzle 47. By arranging in this way, it becomes possible to reduce the bar-shaped dough 19 in a region closer to the solids A and B to the space 5A and 5B side during suction, and the surroundings with respect to the solids A and B The effect that the inner packaging material 5 adheres can be improved.

More specifically, the bar-shaped fabric 19 is continuously discharged. The bottom of the bar-shaped food 19 is supported by the conveyor device 25 that has been lifted from below, and then the conveyor device 25 descends at substantially the same speed as the discharge speed of the discharged food dough 19. Further, the enveloping / cutting device 21 cuts the bar-shaped dough 19 while descending at a slightly higher speed than the discharge speed of the bar-shaped dough 19 from the ascending position. Therefore, the encapsulated food 23 is cut between the lower surface of the enveloping / cutting device 21 and the upper surface of the conveyor device 25 while sandwiching the bar-shaped dough 19. At this time, the solid material A and the solid material B present in the encapsulated food 23 are separated from each other because the inner packaging material 5 is pushed in between them. The present applicant uses the discharge port 45A of the inner packaging material nozzle 45 and the discharge port 47A of the outer material nozzle 47 as means for suppressing the separation between the solid material A and the solid material B present in the encapsulated food 23. It has been found that it is formed into an oval or elliptical shape.

Here, the process of covering and cutting the rod-shaped dough 19 with the six shutter bodies 21A provided in the covering and cutting apparatus 21 will be described. The regular hexagonal opening H, which is a regular polygon formed by being surrounded by the six shutter bodies 21A, is gradually reduced in diameter. Further, the bar-shaped fabric 19 discharged from the outer cover material nozzle 47 is discharged in an oval shape in its horizontal cross section, and flows down in the opening H. First, the bar-shaped dough 19 is pressed by the shutter body 21A from the oblong long axis DL side of the bar-shaped dough 19 at a position above the solids A and B present in the bar-shaped dough 19 (see FIG. 9 (1a)). Further, the opening H is reduced in diameter. At this time, the outer skin material 9 and the inner packaging material 5 flow in the central direction along the long axis DL by the pressing action from the shutter body 21A. Further, since the oval short axis DS side of the rod-shaped fabric 19 is not in contact with the shutter body 21A, the outer skin material 9 and the inner packaging material 5 also flow to the outside along the short axis DS. Then, as the inner packaging material 5 flows in the center direction, the solid A and the solid B move to the center side so as to temporarily approach each other.

Further, the opening H is reduced in diameter, and the rod-like material 19 is pressed by the shutter body 21A from the short axis DS side. (See FIG. 9 (1b)). The rod-shaped fabric 19 is pressed almost uniformly from the six shutter bodies 21A. Then, the opening H is closed, and the encapsulated food 23 is encapsulated and cut from the rod-shaped dough 19 (see FIG. 9 (1c)). At this time, when the opening H is reduced in diameter, the outer skin material 9 and the inner packaging material 5 flow in the center. Further, the inner packaging material 5 also flows below the shutter body 21A. Therefore, the inner packaging material 5 enters between the solid A and the solid B, and separates the solid A and the solid B from each other. However, in the encapsulated food 23, the interval between the encapsulated solids A and B is not greatly displaced from the interval between the solids A and B disposed inside the rod-shaped dough 19 (FIG. 7). FIG. 9 (1a) to (1c)). In addition, since a set of two solids described in Patent Document 1 is in a state where they are in close contact with each other in the vertical direction in the rod-shaped dough, The interval was not constant and was a problem. However, according to the first embodiment of the present invention, the two solid objects A and B can be supplied into the bar-shaped dough 19 in a state of being separated in the horizontal direction. The encapsulated food 23 can be manufactured in a state in which the interval is stable.

The description of the enveloping / cutting device 1 based on the first embodiment of the present invention is generally as described above, but various modifications can be made within the scope of the claims. For example, description will be made using (2a), (2b), and (2c) in FIG. In this example, the stick-shaped dough 91 discharged from the outer cover material nozzle 47 is discharged in a circular shape in the horizontal cross section, and is supplied to the inside of the stick-shaped food 91 in a state where two solid materials are separated from each other. It is a thing. The rod-shaped dough 91 is encapsulated and cut by the six shutter bodies 21A provided in the enveloping / cutting device, whereby the encapsulated food 93 in which the two solids are separated from each other and arranged in the horizontal direction is manufactured. The

Although the food material constituting the rod-shaped doughs 19 and 93 has been described as a two-layer structure including the inner packaging material 5 and the outer skin material 9, it is sufficient that a plurality of solid materials can be wrapped, and the food material includes a single layer or three or more layers of food material. It may be a rod-shaped fabric.

In the above description, the solid A and the solid B are each described as a single solid. For example, a solid group consisting of a plurality of sweet natto is accommodated in the accommodation hole 65 as a single unit, and a plurality of solids is obtained. It is also possible to place the group at a plurality of locations in the encased food 23. Also in this case, a plurality of solid matter groups are arranged in the horizontal direction inside the encapsulated food 23. Further, suction by the suction device is also effectively performed.

Moreover, the solids (solid matter group) supplied to the rod-shaped doughs 19 and 93 at a time are not limited to two, and may be three, for example. In this case, as shown in FIG. 8 (b), the shapes of the discharge port 45A of the inner packaging material nozzle 45 and the discharge port 47A of the outer material nozzle 47 are substantially triangular (shapes obtained by transforming the corners of a regular triangle into a circular arc). In the same phase. In addition, the three pipe members 41A, 41B, and 41C are disposed at the same distance from the center of the discharge port 45A on the inner side of the discharge port 45A and in the direction of each corner from the center (at each corner of the triangle). (This direction is regarded as the direction of the long axis DL.) For example, by aligning the phase of the opening J formed from the three shutter bodies 95 with respect to the discharge port 47A as shown in FIG. The solid material can be moved to the center side without being pressed. Furthermore, the inner packaging material pressed by the shutter body can flow along the direction of the short axis DS toward the outer periphery of the food to be encapsulated, and the solid can be encapsulated and cut without being biased toward the outer periphery of the encapsulated food. The short axis DS is arranged in the direction of the half of the angle formed by the three long axes DL. The same applies to the case of manufacturing a food product containing four or more solid materials.

Next, the enveloping / cutting apparatus 1 based on the second embodiment of the present invention will be described with reference to FIGS. Note that components having the same functions as those of the configuration of the first embodiment are denoted by the same reference numerals, and redundant description is omitted. The rotating disk 64 of the solid material supply device 57 according to the second embodiment includes 15 receiving holes 92 on the circumference P at equal intervals. The accommodation hole 92 is formed so that a part of the first accommodation hole 92A and the second accommodation hole 92B formed from two identical circular holes in a plan view overlap each other. It is shaped like this (herein referred to as a partial polymerization circle). The centers of the circles of the first accommodation hole 92 </ b> A and the second accommodation hole 92 </ b> B are arranged at an equal distance from the center of the rotating disk 64. Further, the opening 63 </ b> B of the tray 63 is formed in a shape corresponding to the accommodation hole 92.

Further, a shutter plate 87 is provided between the opening 63B of the tray 63 and the base plate 59B so as to be able to reciprocate in the horizontal direction. The shutter plate 87 is positioned below the opening 63B when the rotating disk 64 is rotating to stop the solid A and the solid B from falling, and the rotating disk 64 is stopped at a predetermined position. In this case, it moves horizontally toward the inner packaging material hopper 7 and the outer skin material hopper 11 (upper side in FIG. 10, right side in FIG. 12). Then, the solid material A and the solid material B are accommodated in the first accommodation hole 92A and the second accommodation hole 92B, respectively, and the rotating disk 64 is intermittently rotated in one direction (leftward in FIG. 10) by 24 degrees. Thus, the solid A and the solid B are intermittently supplied into the polymerization nozzle 13 at the same time.

The superposition nozzle 13 is provided with an introduction guide member 94 inside the inner cylinder 35. The introduction guide member 94 includes a flange member 95. The protrusion 95D formed on the lower surface of the flange portion 95C of the flange member 95 is fitted into the concave slit 35B of the inner cylinder 35, and the accommodation hole of the rotating disk 64 that stops above the through hole 97. 92 is positioned so as to be arranged concentrically.

A pipe member 96 is fitted to the flange member 95. The pipe member 96 is formed with a through hole 97 as a passage that forms a partially overlapped circle having an outer shape of a figure 8 like the accommodation hole 92 in a plan view. The through hole 97 includes a first through hole 97A and a second through hole 97B, and is formed symmetrically with respect to the center of the flange member 95. The width of the through hole 97, that is, the length in the major axis DL direction in plan view, is longer than the diameter of the circle forming each through hole 97A, 97B and shorter than twice the diameter of the circle. In this example, the diameter is 1.9 times the diameter of the circle. In addition, an inner projecting portion 97C where the arcs of the first through hole 97A and the second through hole 97B intersect with each other is formed in the through hole 97 so as to face each other. Since the distance between the opposed inner protrusions 97C is shorter than the diameter of the circle forming each through hole 97A, 97B, the solids A, B supplied from the rotating disk 64 are separated from the opposed through holes 97B, 97A. The inside of the through hole is dropped at a position close to each other without invading.

The outer shape of the tube member 96 is formed so as to be along the through hole 97 (similarly), and a concave portion 97D is formed on the short diameter DS so as to face each other in plan view (see FIG. 14). In addition, an inclined portion 97TA and an inclined portion 97TB are formed symmetrically at both ends of the lower end portion of the tube member 96 on the long diameter DL of the through hole 97 (see FIG. 11). Further, the inclined portion 97TA and the inclined portion 97TB have upper ends positioned above the discharge port 45C of the inner packaging material nozzle 45, and lower ends thereof, that is, the lower end of the tube member 96 is positioned below the discharge port 45C. (See FIG. 11). The discharge port 45C of the inner packaging material nozzle 45 and the discharge port 47C of the outer cover material nozzle 47 are formed in a circular shape.

The pushing device 71 of the solid material supply device 57 is provided with two rods 77A and 77B. A piston member 98 is screwed to the lower ends of the rod 77A and rod 77B so as to connect them. A piston 77A and a piston 98B concentric with the rod 77A and the rod 77B are formed at the lower portion of the piston member 98, respectively. In addition, an inclined surface 98TA and an inclined surface 98TB are formed on the lower surfaces of the piston 98A and the piston 98B so as to face each other and expand downward. The piston member 98 is provided so as to be able to be inserted into the accommodation hole 92 of the rotating disk 64 which has stopped rotating and the through hole 97 of the introduction guide 94 attached to the superposition nozzle 13. Further, the rods 77A and 77B and the pistons 98A and 98B are formed in a hollow shape, and upper ends of the rods 77A and 77B are communicated with a suction device (not shown).

Here, the covering cutting process based on the second embodiment of the present invention will be described. A rod-shaped dough 19 is discharged from below the superposition nozzle 13. The rod-shaped fabric 19 has a double structure in which the inner packaging material 5 is covered with the outer skin material 7. The inner packaging material 5 passes between the inner circumferential surface of the inner packaging material nozzle 45 and the outer circumferential surface of the tube member 96 of the introduction guide 94 and is discharged from the discharge port 45 </ b> A of the inner packaging material nozzle 45. At this time, since the inner packaging material 5 flows down along the outer shape of the tube member 96, a bag-like space 6 in which the space 6 </ b> A and the space 6 </ b> B are integrated is formed inside the inner packaging material 5. This bag-like space 6 has a shape of a partially polymerized circle like an outer shape of a figure 8 in its horizontal cross section.

Further, the inner packaging material 5 that flows downward from the lower end of the tube member 96 is reduced in diameter because it flows in the central direction as the inner diameter of the outer skin material nozzle 47 decreases downward, and the bag inside the inner packaging material 5 is reduced. The shape space 6 is also deformed to be small. Further, since the inclined portions 97TA and 97TB are provided at the lower end of the tube member 96, the inner packaging material 5 flows from the long diameter DL side of the tube member 96 to the bag-like space 6 side before the other lower end portions. The bag-like space 6 is reduced.

The rotating disk 64 of the solid supply device 57 rotates 24 degrees in the direction of arrow T and stops again. When the shutter plate 87 is moved from the lower side of the rotary disk 64 to the outside, the solids A and B are simultaneously dropped from the first accommodation hole 92A and the second accommodation hole 92B of the rotary disk 64, and the space 5A of the inner packaging material 5 is dropped. , 5B, respectively. Further, simultaneously with the stop of the rotating disk 64, the rodless cylinder of the pushing device 71 is driven, and the first piston 98A and the second piston 98B of the piston member 98 that have stopped at the raised position are respectively accommodated in the receiving holes 92A and 92B. Then, the inside of the first through hole 97A and the second through hole 97B of the pipe member 96 provided in the introduction guide 94 is lowered. Then, the inclined surface 98TA of the piston 98A and the inclined surface 98TB of the piston 98B press the solid A and the solid B obliquely downward toward the center, and move the solid A and the solid B so as to approach each other. While making it closely_contact | adhere to the inner packaging material 5 which forms the bottom part of the said bag-shaped space, the inner packaging material 5 interposes between the said solid substance A and the solid substance B, and arrange | positions it in a horizontal direction so that it may not mutually adhere.

The inclined surface 98TA of the piston 98A and the inclined surface 98TB of the piston 98B are pressing surfaces that press the solid material A and the solid material B toward the center, and are not limited to a planar shape, and may be curved surfaces, bent surfaces, or the like. Any configuration may be used as long as the solid can be pressed to a required position.

The piston member 98 lowered to the descent stop position is raised again. Before or after the piston member 98 is raised or when it is raised, the suction device is operated, and air in the bag-like space 6 of the inner packaging material 5 is drawn from the tips of the hollow first piston 98A and the second piston 98B. At the same time, the enveloping / cutting device 21 is operated to produce the encapsulated food 23 containing the solids A and B along the horizontal direction from the rod-shaped dough 19.

In the same manner as the covering cutting process based on the first embodiment, the rod-shaped dough 19 containing the solid material A and the solid material B is provided between the lower surface of the covering cutting device 21 and the upper surface of the conveyor device 25. The encapsulated food 23 is cut while being pinched. More specifically, the rod-shaped dough 19 discharged from the outer cover material nozzle 47 flows down in the opening H, and the opening H is reduced in diameter at a position above the solids A and B present in the rod-shaped dough 19. Accordingly, the pressing action is equally received from the six shutter bodies 21A. At this time, due to the pressing action from the shutter body 21A, the outer skin material 9 and the inner packaging material 5 flow in the center direction and the up-down direction of the shutter body 21A (up-down direction on the paper surface of FIG. 13). Therefore, the inner packaging material 5 enters between the solids A and B that approach each other while reducing the bag-like space 6, and gradually separates the solids A and B from each other. Further, the opening H is reduced in diameter, and the encapsulated food 23 is encapsulated and cut from the rod-shaped dough 19. During this time, the inner packaging material 5 continues to enter between the solid A and the solid B, and further separates the solid A and the solid B. Thereafter, the encapsulated food 23 is embossed, so that the solid A and the solid B in the final product are arranged in the horizontal direction at appropriate intervals.

Further, in conjunction with the cutting operation of the enveloping / cutting device 21, the suction device is operated before and after the piston member 98 is raised or when it is raised, so that the hollow first piston 98A and the second piston are formed. By sucking air in the bag-like space 6 of the inner packaging material 5 from the tip of 98B, the inside of the bag-like space 6 containing the solids A and B is decompressed and reduced. Accordingly, since the inner packaging material 5 around the respective solid materials A and B moves so as to be in close contact with each other, the formation of a gap with the inner packaging material 5 around the respective solid materials A and B can be suppressed. .

In the enveloping / cutting device 1 according to the second embodiment of the present invention, the shape of the discharge port 45C of the inner packaging material nozzle 45 and the shape of the discharge port 47C of the outer material nozzle 47 are described as circles. Similarly to the first embodiment of the present invention, an oval shape or an oval shape may be used, and the shutter body 21A may be arranged corresponding to the shape.

As can be understood from the above description, a plurality of solid materials are individually dropped in individual rod passages (tube members 41A and 41B, first through-holes 97A and second through-holes 97B), and thereby a plurality of solid materials are placed in the rod-shaped dough. Can be supplied without being in close contact with each other.

Moreover, a foodstuff material can be closely_contact | adhered to solid substance by connecting a suction device to the piston with which the solid substance supply apparatus was equipped, and attracting | sucking air from the bag-shaped space in stick-shaped dough.
