Description

[Technical field]

[0001] The present invention relates to a nozzle, an encrusting device, and an encrusting method. [Background technology]

[0002] A nozzle is known that causes a first food ingredient to flow inside a second food ingredient that flows out from an outer nozzle in order to encase a first food ingredient with a second food ingredient (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 52-133293 Summary of the Invention [Problem to be solved by the invention]

[0004] With the filling discharge nozzle (nozzle) described in Patent Document 1, if the filling (first ingredient) being discharged is changed, the fluidity of the first ingredient changes and the flow rate becomes unsuitable for enveloping the filling, and it may become impossible to envelop the first ingredient with the outer shell (second ingredient).

[0005] An object of the present invention is to provide a nozzle, an encrusting device, and an encrusting method that can dispense a first food ingredient at a flow rate suitable for encrusting when encrusting a first food ingredient with a second food ingredient. [Means for solving the problem]

[0006] The nozzle of the present invention is a nozzle that is positioned inside an outer nozzle from which a second food ingredient flows out, and that flows a first food ingredient inside the second food ingredient, and is equipped with a main body portion into which the first food ingredient flows and through an internal flow path, a constriction portion that is detachable from the main body portion and constricts the flow path of the main body portion, and an outlet portion that is provided with an outlet path that communicates with the flow path of the main body portion, and through which the first food ingredient flows and exits via the outlet path.

[0007] According to the present invention, since the restricting section that restricts the flow path inside the main body of the nozzle is detachable from the main body, the flow rate of the first ingredient can be made suitable for the filling by attaching and detaching the restricting section in accordance with the fluidity of the first ingredient. Therefore, when the first ingredient is filled with the second ingredient, the first ingredient can be discharged at a flow rate suitable for the filling.

[0008] The nozzle of the present invention may include a second throttle portion that is detachably attached to the outflow portion and that throttles the outflow path of the outflow portion.

[0009] According to the present invention, the second throttling section which narrows the outflow path within the outflow section is detachable from the outflow section. Therefore, by attaching and detaching the second throttling section in accordance with the fluidity of the first food ingredient, the flow rate of the first food ingredient can be made suitable for the filling.

[0010] In the nozzle of the present invention, a plurality of the throttling portions are provided, each having a different amount of throttling of the flow passage of the main body portion, and the plurality of the throttling portions are selectively attached to the main body portion.

[0011] According to the present invention, multiple throttling sections with different throttling amounts can be selectively attached to the main body section, so that an appropriate throttling section can be used according to the fluidity of the first ingredient, making the flow rate of the first ingredient more suitable for enrobing.

[0012] The encrusting device of the present invention comprises an inner nozzle consisting of the nozzle of the present invention described above, and an outer nozzle with the nozzle arranged inside, and causes the first ingredient to flow out of the inner nozzle inside the second ingredient flowing out of the outer nozzle, thereby encrusting the first ingredient with the second ingredient.

[0013] According to the present invention, the first food ingredient can be discharged at a flow rate suitable for enveloping, so that the first food ingredient can be enveloped with the second food ingredient.

[0014] The encrusting method of the present invention carries out a step of discharging the first ingredient from the nozzle of the present invention described above, and a step of discharging the second ingredient from an outer nozzle arranged inside the nozzle, thereby discharging the first ingredient inside the second ingredient and enrobing the first ingredient with the second ingredient.

[0015] According to the present invention, the same effects as those of the above-mentioned encrusting device can be obtained. [Brief description of the drawings]

[0022] The inner nozzle 4 communicates with the supply pipe 22 of the first food ingredient supply unit 2 and is disposed inside the outer nozzle 5 to cause the first food ingredient to flow inside the second food ingredient. The configuration of the inner nozzle 4 will be described later.

[0023] The outer nozzle 5 communicates with the supply pipe 32 of the second food ingredient supply unit 3, and is disposed so that the inner nozzle 4 is located on the inside. The outer nozzle 5 includes a locking portion 51 that is locked to the support portion 6, and a reduced diameter portion 52 that is reduced in diameter from one axial end (upper end) to the other axial end (lower end), and the second food ingredient flows out from the reduced diameter portion 52. The locking portion 51 is configured as a recess provided on the outer circumferential surface of the outer nozzle 5 .

[0024] The support section 6 includes a connecting pipe 61 connected to the supply pipe 22 of the first food supply section 2 and the supply pipe 32 of the second food supply section 3, an inner nozzle fixing section 62 for fixing the inner nozzle 4 to the connecting pipe 61, and an outer nozzle fixing section 63 for fixing the outer nozzle 5 to the connecting pipe 61.

[0025] The connecting pipe 61 is formed in a substantially cross shape. The connecting pipe 61 includes a first pipe section 61A connected to the supply pipes 22 and 32 via an annular connecting member 64 having a seal material such as a packing or an O-ring, a second pipe section 61B provided on the outer circumferential surface of the first pipe section 61A and communicating with the first pipe section 61A, and a third pipe section 61C provided on the outer circumferential surface of the first pipe section 61A at a position on a substantially extended line of the second pipe section 61B sandwiching the first pipe section 61A and communicating with the first pipe section 61A. The inner nozzle 4 is inserted through the connecting pipe 61 from the second pipe section 61B to the third pipe section 61C so as to cross the first pipe section 61A in a direction perpendicular to its axial direction, and the supply pipe 22 side portion of the first pipe section 61A communicates with the supply pipe 22 and the inner nozzle 4, and the supply pipe 32 side portion of the first pipe section 61A communicates with the supply pipe 32 and the outer nozzle 5.

[0026] The inner nozzle fixing part 62 screws into the second pipe part 61B of the connecting pipe 61 with the inner nozzle 4 inserted through the connecting pipe 61, fixing the inner nozzle 4 to the connecting pipe 61. The inner nozzle fixing part 62 includes a cylindrical tubular part 62A whose inner surface screws into the outer surface of the second pipe part 61B, and an end surface part 62B covering one axial end of the tubular part 62A. The end surface portion 62B is provided with a through hole 62C into which a throttle portion 42 of the inner nozzle 4, which will be described later, is inserted.

[0027] The outer-nozzle fixing part 63 screws into the third pipe part 61C with the outer nozzle 5 disposed so as to cover the inner nozzle 4 protruding from the third pipe part 61C, and fixes the outer nozzle 5 to the connecting pipe 61. The outer-nozzle fixing part 63 includes a cylindrical tubular part 63A whose inner surface screws into the outer surface of the third pipe part 61C, and an end surface part 63B covering one axial end of the tubular part 63A. The end surface portion 63B has a through hole 63C into which the reduced diameter portion 52 of the outer nozzle 5 is inserted, and when the reduced diameter portion 52 is inserted into the through hole 63C, the inner edge of the end surface portion 63B is engaged with the engaging portion 51 of the outer nozzle 5.

[0028] The cutting section 7 includes a plurality of shutters 71 arranged below the inner nozzle 4 and the outer nozzle 5, and a driving device such as a linear motor that reciprocates the plurality of shutters 71 so as to move them toward and away from each other.

[0029] [Inner nozzle configuration] As shown in Figures 2(A) and (B) and Figures 3(A) and (B), the inner nozzle 4 comprises a main body portion 41 into which the first food ingredient flows and through an internal flow path 41A, constricting portions 42 and 43 which are detachable from the main body portion 41 and constrict the flow path 41A of the main body portion 41, an outlet portion 44 which is provided with an outlet path 44A communicating with the flow path 41A of the main body portion 41 and through which the first food ingredient flows and exits through the outlet path 44A, a second constricting portion 45 which is detachable from the outlet portion 44 and constricts the outlet path 44A of the outlet portion 44, and a plug portion 46 which is attached to the main body portion 41 when the constricting portions 42 and 43 are removed.

[0030] The main body portion 41, the constriction portions 42, 43, the outflow portion 44, the second constriction portion 45, and the plug portion 46 are formed from plastic, metal, ceramic, etc., and in this embodiment, the main body portion 41 is formed from plastic, and the constriction portions 42, 43, the outflow portion 44, the second constriction portion 45, and the plug portion 46 are formed from metal.

[0031] The main body 41 has a generally cylindrical shape and includes a flow passage 41A, an insertion hole 41B into which the throttle portions 42 and 43 are inserted, and a flange portion 41C provided at one end in the axial direction and protruding in the radial direction. The flow path 41A is constituted by a through hole formed from a side surface 41D of the main body 41 to one (lower) end surface 41E in the axial direction, and is formed into a substantially L-shape in cross section. The insertion hole 41B is a through hole formed from the other (upper) end face 41F of the main body 41 to the flow passage 41A, and extends in the axial direction of the main body 41.

[0032] A plurality of throttle sections 42, 43 are provided, each of which has a different throttle amount for flow passage 41A of main body 41, and the plurality of throttle sections 42, 43 are selectively attached to main body 41.

[0033] The constriction portion 42 includes a shaft portion 42A having a cross-sectional shape approximately the same as the cross-sectional shape of the insertion hole 41B, a flange portion 42B formed midway along one axial (upper) side of the shaft portion 42A, and a tapered portion 42C formed at the end of the other axial (lower) side of the shaft portion 42A and gradually narrowing toward the tip.

[0034] Like the throttle section 42, the throttle section 43 has a shaft section 43A, a flange section 43B, and a tapered section 43C, but the shape of the shaft section 43A is different from that of the shaft section 42A in order to reduce the amount of throttling compared to the throttle section 42. The shaft section 43A is a stepped shaft that is narrower on the tapered section 43C side, and the portion located within the flow path 41A when the flange section 43B abuts against the end face 41F of the main body section 41 is narrower than the upper portion.

[0035] The outflow portion 44 includes an outflow path 44A, an annular fitting portion 44B that forms one end of the outflow path 44A and fits into the flow path 41A at the end face 41E of the main body portion 41, and a reduced diameter portion 44C that forms the other end of the outflow path 44A and causes the outflow path 44A to reduce in diameter as it moves away from the fitting portion 44B.

[0036] The second throttle portion 45 is generally shaped like a truncated cone tapering from one end to the other, and is inserted into the outflow passage 44A of the outflow portion 44 and engaged with the reduced diameter portion 44C. The second throttle portion 45 has a plurality of through holes 45A penetrating from one end to the other end. The through holes 45A are formed to have a circular cross section, and extend parallel to each other in the front-rear and left-right directions.

[0037] The plug portion 46 is inserted into the insertion hole 41B in place of the throttle portions 42 and 43, and is attached to the main body portion 41. Like the throttle portion 42, the plug portion 46 has a shaft portion 46A, a flange portion 46B, and a tapered portion 46C, but the length of the shaft portion 46A is shorter than the length of the shaft portion 42A. The plug portion 46 is formed such that when the flange portion 46B abuts against the end face 41F of the main body portion 41, only the tapered portion 46C protrudes from the insertion hole 41B, and the flow path 41A of the main body portion 41 is not throttled, or the amount of throttling is very small.

[0038] [Wrapping method] A method for enrobing a first food ingredient in a second food ingredient by the enrobing device 1 will be described with reference to Fig. 1 to Fig. 3(A) and (B). A connecting pipe 61 of the support unit 6 is connected to the supply pipes 22, 32 of the first food ingredient supply unit 2 and the second food ingredient supply unit 3. The outer nozzle 5 may be fixed to the connecting pipe 61 at this point, or the outer nozzle 5 may be fixed to the connecting pipe 61 after the inner nozzle 4 is fixed to the connecting pipe 61.

[0039] First, the user of the enveloping device 1 selects the constricting portion 42, 43 suitable for the first food ingredient to be used in the filling. In this embodiment, the constricting portion 42 shown in Figs. 2(A) and (B) is selected. Next, the user inserts the second constricting portion 45 into the outlet passage 44A of the outlet portion 44 to engage with the reduced diameter portion 44C, and engages the fitting portion 44B of the outlet portion 44 with the end surface 41E of the main body portion 41. The user also inserts the constricting portion 42 into the insertion hole 41B from the outside of the main body portion 41. As a result, the constricting portion 42 is inserted into the flow path 41A of the main body portion 41, and the flow path 41A is constricted. At this time, the flange portion 42B of the constricting portion 42 abuts against the end surface 41F of the main body portion 41, so that the constricting portion 42 is positioned in the main body portion 41 and is not inserted any further. The user may insert the inner nozzle 4 into the connecting pipe 61 at this point, or may insert the inner nozzle 4 into the connecting pipe 61 without the throttle portion 42 inserted therein when the fitting portion 44B of the outlet portion 44 is fitted into the end face 41E of the main body portion 41. When the inner nozzle 4 is inserted into the connecting pipe 61, the flange portion 41C is engaged with the axial end face of the second pipe portion 61B of the connecting pipe 61. Thereafter, the user screws the inner nozzle fixing portion 62 into the second pipe portion 61B of the connecting pipe 61 so that the throttle portion 42 is inserted into the through hole 62C of the inner nozzle fixing portion 62, thereby fixing the inner nozzle 4 to the connecting pipe 61.

[0040] Next, the user places the first ingredient in hopper 21 and the second ingredient in hopper 31, and then inputs a signal to start automatic operation via an operation input unit such as a touch panel or keyboard. Then, the switching valves of the first ingredient supply unit 2 and the second ingredient supply unit 3 are switched, and the hopper 21 and the inner nozzle 4, and the hopper 31 and the outer nozzle 5 are connected to each other. As a result, as shown in FIG. 1, the first ingredient is supplied from the hopper 21 to the inner nozzle 4, and the second ingredient is supplied from the hopper 31 to the outer nozzle 5. As a result, inside the second ingredient that flows out from the outer nozzle 5, the first ingredient flows out from the inner nozzle 4 and extends downward together with the second ingredient on the outside, and the first ingredient is surrounded by the second ingredient and hangs down as an enrobed ingredient.

[0041] Next, the driving device in the cutting unit 7 is driven, and the multiple shutters 71 approach each other as shown by the two-dot chain line in Fig. 1. As a result, the enclosed food material is cut by the shutters 71, and an enclosed food product is formed in which the first food material is entirely wrapped in the second food material. The enclosed food product is packaged as necessary and placed on a conveyer such as a belt conveyer or roller conveyer disposed below the cutting unit 7, and is transported by the conveyer to the next process, such as a heating process or a cooling process for the enclosed food product.

[0042] According to the embodiment described above, the throttle units 42, 43 that throttle the flow path 41A in the main body 41 of the inner nozzle 4 are detachable from the main body 41, so that the flow rate of the first food ingredient can be made suitable for envelopment by attaching and detaching the throttle units 42, 43 in accordance with the fluidity of the first food ingredient. Therefore, when the first food ingredient is enveloped with the second food ingredient, the first food ingredient can be discharged at a flow rate suitable for envelopment.

[0043] For example, if the first ingredient has high fluidity, an unintended large amount of the first ingredient may naturally fall from the inner nozzle 4, making it impossible to encase the second ingredient. For this reason, it is beneficial in enrobing to attach and detach the constricting sections 42, 43 and the second constricting section 45 in accordance with the fluidity of the first ingredient. The attachment and detachment of the constricting sections 42, 43 and the second constricting section 45 is performed by removing the inner nozzle fixing section 62 from the second tube section 61B of the connecting tube 61, and then inserting and removing the constricting sections 42, 43, or by removing the outlet section 44 from the inner nozzle 4 pulled out of the connecting tube 61, and attaching and detaching the second constricting section 45.

[0044] In addition, the second throttling section 45, which narrows the outflow path 44A within the outflow section 44, is detachable from the outflow section 44. Therefore, by attaching and detaching the second throttling section 45 in accordance with the fluidity of the first food ingredient, the flow rate of the first food ingredient can be made suitable for the filling.

[0045] In addition, since a plurality of constricting sections 42, 43 with different constriction amounts can be selectively attached to the main body section 41, an appropriate constricting section 42, 43 can be used in accordance with the fluidity of the first ingredient, making the flow rate of the first ingredient more suitable for enrobing.

[0046] As described above, the best configuration, method, etc. for carrying out the present invention are disclosed in the above description, but the present invention is not limited thereto. That is, the present invention is mainly illustrated and described with respect to a specific embodiment, but a person skilled in the art can make various modifications to the above-described embodiment in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. In addition, the description of the shape, material, etc. disclosed above, which is limited, is illustratively described to facilitate understanding of the present invention, and does not limit the present invention, so that the description of the names of the members from which some or all of the limitations of the shape, material, etc. are removed is included in the present invention.

[0047] For example, the first ingredient supply unit 2 and the second ingredient supply unit 3 may each include a pressure-feed unit that pressure-feeds the ingredients that they supply. The pressure-feed unit may be, for example, a pump such as a vane pump or a plunger pump provided in the supply pipes 22 and 32, or may be a pusher member such as a piston that pushes out each ingredient by a reciprocating motion.

[0048] The inner nozzle 4 may have a configuration in which the main body 41 and the outflow passage 44A are indirectly connected, or may have a connection part disposed between the main body 41 and the outflow passage 44A to connect them. In this case, the connection part has a communication passage that communicates between the flow passage 41A of the main body 41 and the outflow passage 44A of the outflow part 44. Flow path 41A may be curved from side surface 41D of main body 41 to end surface 41E in the axial direction, and may be formed into a substantially arc shape in cross section.

[0049] The constriction sections 42, 43 may be attached and detached to the main body section 41 by being inserted and removed into the insertion hole 41B of the main body section 41 with the inner nozzle 4 arranged inside the outer nozzle 5 and the inner nozzle 4 connected to the supply pipe 22 of the first food supply section 2. The throttle portion 42 may be formed so that the throttle amount can be changed by changing its length, for example, as shown in FIG. 4(A). The tapered portions 42C, 43C may be formed in a frustum shape, such as a truncated cone or a truncated pyramid, or may be formed in a cone or pyramid shape.

[0050] The outflow portion 44 may be fixed to the main body portion 41 with a fixing member such as a bolt instead of or in addition to the fitting portion 44B, or may be formed integrally with the main body portion 41. The fitting portion 44B may be formed to be screwed into the end surface 41E of the main body portion 41.

[0051] A plurality of second throttling sections 45 having different throttling amounts of the outflow passage 44A may be provided, and the plurality of second throttling sections 45 may be selectively attached to the outflow section 44. In this case, the second throttling section 45 may be formed so as to change the throttling amount depending on the number of through holes 45A, or may be formed so as to change the throttling amount depending on the diameter of the through holes 45A. The through holes 45A do not have to be formed parallel to one another. For example, the plurality of through holes 45A may be formed so as to approach or separate from one another toward the tip of the second throttle portion 45. The number and cross-sectional shape of the through holes 45A are not particularly limited; there may be one or more through holes 45A, and the cross-section may be any shape, such as an ellipse, an oval, an arc, a square, a rectangle, a polygon, a ring, or a polygonal ring. When it is determined that the second narrowing section 45 is not necessary after considering the fluidity of the first food material, it is possible to select not to use the second narrowing section 45. In this case, the narrowing section 42 may be formed into a shape and length as shown in FIG. 4(B), for example, so that the narrowing section 42 also serves as the second narrowing section. In this case, the tapered section 42C may be tapered so that the gap between the tapered section 42C and the outflow passage 44A is constant, as shown in FIG. 4(B), or may be tapered so that the gap between the tapered section 42C and the outflow passage 44A becomes wider or narrower toward the tip. The tip of the tapered section 42C may be located at the same position as the tip of the outflow section 44, or may be located inside or outside the tip of the outflow section 44.

[0052] Plug portion 46 may be formed such that, when flange portion 46B abuts against end surface 41F of main body portion 41, tapered portion 46C is positioned within insertion hole 41B. The tapered portion 46C may be formed in a frustum shape such as a truncated cone or a truncated pyramid, or may be formed in a cone or pyramid shape, or the tapered portion 46C may not be provided.

[0053] The outer nozzle 5 does not have to include the locking portion 51. In this case, the inner edge of the end face portion 63B of the outer-nozzle fixing portion 63 may be locked to the outer circumferential surface of the reduced diameter portion 52. The locking portion 51 may be configured as a protrusion provided on the outer circumferential surface of the outer nozzle 5 .

[0054] The support portion 6 does not have to be formed separately from the supply pipe 22 of the first food supply portion 2 and the supply pipe 32 of the second food supply portion 3, and a portion of the supply pipe 22 or the supply pipe 32 may be formed in the same manner as the support portion 6, and the supply pipe 22 and the supply pipe 32 may be connected to each other.

[0055] The driving equipment in the above-described embodiments may be electric equipment such as a rotary motor, a linear motor, a single-axis robot, or a multi-joint robot having joints on two or more axes, or an actuator such as an air cylinder, a hydraulic cylinder, a rodless cylinder, or a rotary cylinder, or a direct or indirect combination of these may also be used.

[0056] As the first food material, a liquid or paste-like food material other than those exemplified in the above embodiment may be used. As the second food ingredient, food ingredients other than those exemplified in the above embodiment may be used. For example, dough such as pie dough or bread dough, or paste food ingredients such as fish paste products or meat paste products may be used. [Explanation of symbols]
