Each of the extrusion ports communicates with a corresponding gear chamber defined by the partition walls. preferable.

  According to the above aspect, by providing a gear chamber corresponding to each extrusion port, the pressure of the raw material extruded from each extrusion port can be made uniform, and variation in products due to unevenness in the extrusion pressure of the raw material is reduced. can do. Moreover, it becomes possible to extrude a raw material from a plurality of extrusion ports by a common drive source. Further, the first raw material extrusion port and the second raw material extrusion port can be arranged in two rows and arranged at a predetermined interval.

  According to the present invention, the raw material extruded from the first raw material extrusion port and the second raw material extrusion port is introduced into the discharge port of the nozzle plate through the corresponding passage hole of the slide plate, and the slide plate reciprocates. Accordingly, the first material passage hole and the second material passage hole are alternately communicated with one discharge port, so that the first material and the second material are alternately extruded from the discharge port. A rod-shaped food product in which the first raw material portion and the second raw material portion are alternately arranged along the axial direction can be produced.

  In the present invention, the raw material extruding means means means for extruding the raw material by applying a certain pressure to the raw material.For example, a means for extruding after sucking the raw material by a pump, or a vertical spiral screw in the raw material hopper. Examples thereof include means for extruding by applying pressure to a provided feed screw and a sealed hopper. Among these, a pump is preferable, and a gear pump is particularly preferable from the viewpoint of the space of the apparatus and the viewpoint of supplying raw materials separately.

  And the raw material extruded by the extrusion means is supplied to the receiving port of a slide plate. When the raw material extruding means is a pump, it is preferable that one pump corresponds to one receiving port of the slide plate. This is because the raw material can be supplied to the receiving port of each slide plate with an equal pressure.

  In the present invention, the slide plate is a member that is arranged between the push-out means and the nozzle plate and slides. Although the moving direction includes a linear direction and a circumferential direction, it is preferable to reciprocate in the linear direction. According to this, it is possible to provide a large number of outlets for stick-shaped foods along the linear direction of reciprocating movement, and it is possible to provide a certain interval between the stick-shaped foods when the protruding stick-shaped foods are placed on the conveyor. is there.

  On the side of the slide plate that is in contact with the extrusion means, there are provided a first raw material receiving port and a second raw material receiving port, and the first raw material extrusion port and the second raw material receiving port correspond to the respective receiving ports. It has a structure in which an extrusion port is arranged. Furthermore, it is preferable that the extrusion port for the first material and the extrusion port for the second material are arranged so as not to overlap with the reciprocating direction of the slide plate. As a result, the first raw material receiving port and the second raw material receiving port can be arranged so that the receiving ports do not buffer each other even if the sliding plate has a length that extends in the reciprocating direction of the slide plate. .

  On the side of the slide plate in contact with the nozzle plate, a first raw material outlet that communicates with the first raw material inlet and a second raw material outlet that communicates with the second raw material inlet are provided. The passage from the first raw material receiving port to the first raw material outlet forms the first raw material passage hole in the present invention, and the passage from the second raw material receiving port to the second raw material outlet is in the present invention. A passage hole for the second raw material is formed. In addition, although one receiving port can be provided with respect to several outflow ports of each raw material and a receiving port can be made common, it is preferable to make one receiving port correspond to one outflow port. The reason is that, for example, when there is one receiving port and a plurality of slide plates are used as the outlet, when the food material is a viscous material such as chocolate, it exists at the center of the receiving port of the slide plate. This is because the pressure does not become uniform between the outlet and the outlet present at the end, making it difficult to produce a uniform bar-shaped food. Therefore, it is most preferable that one receiving port and one pump are provided corresponding to one of the outlets of the slide plate.

  In addition, the outlet of the first material and the outlet of the second material of the slide plate are alternately arranged in a line along the reciprocation direction at intervals of the reciprocation width of the slide plate. The outlets are also preferably arranged at the same intervals as described above. As a result, when the slide plate is reciprocated, each outlet can be alternately communicated with a pair of adjacent outlets, whereby the first raw material flows into one outlet of the nozzle plate. The outlet and the outlet of the second raw material can be alternately communicated.

  Furthermore, it is preferable that the receiving ports communicating with the outlet of the slide plate on a one-to-one basis are arranged in two rows in the slide direction of the slide plate and at an interval twice the reciprocating movement width. Furthermore, it is more preferable that the receiving port of one row out of the two rows is shifted from the receiving port of the other row by one reciprocating movement width in the reciprocating movement direction. The internal passages extending from the receiving ports to the corresponding outlets are formed obliquely with respect to the slide plate surface, and the outlets of the first material and the second material are alternately arranged in a row on the opposite surface side of the slide plate. It is preferable to arrange in. As a result, the first raw material and the second raw material can be supplied to each receiving port of the slide plate without mixing, and the outlets of the first raw material and the second raw material of the slide plate are alternately arranged in a row without any structural difficulty. Can be arranged.

  In addition, it is preferable that the internal passage from the receiving opening of the slide plate to the corresponding outlet is formed at an angle of 65 to 80 degrees from the horizontal direction with respect to the slide plate surface. Thereby, a foodstuff raw material can be smoothly poured from an acceptance port to an outflow port.

  In the present invention, it is preferable to make the cycle of sliding the slide plate constant. This cycle is the number of rotations of the slide plate per unit time in the case of a circular slide plate, and the number of reciprocations of the slide plate per unit time in the case of a rectangular slide plate.

  The cycle of sliding the slide plate corresponds to the switching time of the first raw material outlet and the second raw material outlet provided on the slide plate. Therefore, when the rotation speed per unit time is the same, the ratio of the first raw material and the second raw material in the stick-shaped food becomes the same, and a uniform stick-shaped food can be manufactured. Similarly, when the time required for the outbound path and the return path in the number of round trips per unit time is the same time, the ratio of the first raw material and the second raw material in the bar-shaped food becomes the same, and a uniform bar-shaped food can be manufactured. . In addition, the rotation speed per unit time and the reciprocation number of the slide plate per unit time can be suitably changed with the stick-shaped foodstuff to manufacture. For example, when the switching time of the first raw material and the second raw material is made faster, the raw material in the rod-shaped food is switched more and a striped pattern can be formed in the longitudinal direction. On the other hand, if the switching time of the first ingredient and the second ingredient is made slow, the change of ingredients in the rod-shaped foods is reduced, and the ingredients change gradually, so the texture and color change in one rod-shaped food I can enjoy it.

  In addition, when the 1st raw material and the 2nd raw material are fat and oil confectionery doughs, such as chocolate, the moving speed is preferably 300 to 5000 mm / min, and in this case, the slide cycle is preferably 3 to 200 times / min. Furthermore, when the moving speed of the raw material is Vmm / min and the slide cycle is D times / min, V / D is preferably 25 to 110 mm. Here, in the present invention, the “moving speed” is not a discharge speed from the discharge port of the nozzle plate (a speed passing through the discharge port), but after the oily confectionery dough such as chocolate is placed on a conveyor or the like after being discharged. Means the moving speed of the molded product in a solidified state.

  In the present invention, the nozzle plate means a member that is in contact with the slide plate but does not move in synchronization with the slide plate and has a discharge port. The discharge port of the nozzle plate is at a position where it is joined to the outlet of the slide plate, and when the slide plate slides, the outlet of the first raw material and the outlet of the second raw material are switched to each other. The second raw material switched from the first raw material is alternately projected from the discharge port of the nozzle plate. In addition, it is preferable that the internal diameter of the discharge port of a nozzle plate is 3-10 mm.

Are provided with a plurality of driven shaft side gears 43 at predetermined intervals in the axial direction. When the corresponding main shaft 41 and driven shaft gear 43 mesh with each other and the main shaft 33 rotates, the driven shaft 35 also rotates via the gear.

  In addition, a partition wall 49 is disposed between adjacent ones of the main shaft side gear 41 and the driven shaft side gear 43 arranged in the axial direction via an annular spacer 45, and a pair of teeth that mesh with each other by the partition wall 49. A pump chamber 53 surrounding the main drive shaft side gear 41 and the driven shaft side gear 43 is formed. In FIG. 3, the gear pump that supplies the first raw material (left in the figure) is cut at the partition 49, and the gear pump that supplies the second raw material (right in the figure) is cut inside the pump chamber 53. Since it is in a state, the pump chamber 53 appears only in the gear pump that supplies the second raw material.

  As shown in FIG. 8, the deposition plate 100 is provided with a first material groove 103 a and a second material groove 103 b on the left and right sides of the center line C. The interval between the grooves is the same as twice the reciprocating width. The positions of the first raw material groove 103a and the second raw material groove 103b are the same width as the reciprocating movement width and shifted in the reciprocating movement direction. The raw material passage of the deposition plate 100 includes grooves 103a and 103b for flowing the first raw material and the second raw material, holes 105 for guiding the raw materials to the lower part of the deposition plate, and pushing of the first raw material that opens to the lower surface of the deposition plate. It is comprised by the exit 101a and the extrusion port 101b of the 2nd raw material. The extrusion ports 101a and 101b are arranged in two rows on the left and right of the center line C.

  Referring to FIGS. 2, 3, and 8 together, the first raw material extrusion port 39 a that opens to the lower surface of the case 30 is aligned with the first raw material groove 103 a of the deposition plate 100 and opens to the lower surface of the case 30. The two raw material extrusion ports 39 b are aligned with the second raw material groove 103 b of the deposition plate 100. As described above, the first raw material groove 103a communicates with the first raw material extrusion port 101a opened on the lower surface of the deposition plate 100 through the hole 105a, and the second raw material groove 103b has the hole 105b. The second raw material extrusion port 101b is opened to the lower surface of the deposition plate 100.

  2, 3, and 9, the first raw material receiving port 203 a and the second raw material receiving port 203 b are arranged on the upper surface of the slide plate 200 in two rows one by one in the reciprocating direction. The interval between the respective receiving ports 203a or 203b is twice the reciprocating width of the slide plate 200. The positions of the first raw material receiving port 203a and the second raw material receiving port 203b are the same length as the reciprocating width and are shifted in the reciprocating direction. Further, the width of each receiving port 203a, 203b in the direction perpendicular to the reciprocating direction is about 20% larger than the diameter of the depot plate extrusion port 101a, 101b, and the width in the reciprocating direction is equal to the reciprocating width and the depot plate. The oval mold is slightly longer than the length of the extrusion port 101 plus the diameter.

  As described above, the first raw material receiving port 203a and the second raw material receiving port 203b have an oval shape that is long in the reciprocating direction, so that even if the slide plate 200 reciprocates, the corresponding deposit It always communicates with the plate extrusion ports 101a and 101b.

  Each receiving port 203a, 203b of the slide plate 200 extends obliquely downward in the direction of the center line of the slide plate 200, and its lower end opens to the lower surface of the slide plate 200. A material outlet 201b is formed. And the passage which connects the said receiving ports 203a and 203b and the outflow ports 201a and 201b has comprised the passage holes 205a and 205b in this invention.

  In addition, it is preferable that the internal passages from the receiving ports 203a and 203b of the slide plate 200 to the corresponding outlets 201a and 201b are formed at an angle of 65 to 80 degrees with respect to the surface of the slide plate 200 from the horizontal direction. The angle of the slide plate of FIG. 9 is 72 degrees. Thereby, a food raw material can be smoothly poured from the receiving ports 203a and 203b to the outflow ports 201a and 201b.

  In addition, the first material outlet 201a and the second material outlet 201b opened on the lower surface of the slide plate 200 are alternately arranged in a line along the reciprocating direction at intervals of the reciprocating width of the slide plate 200. Similarly, the discharge openings 301 of the nozzle plate are also arranged at the same intervals as described above. As a result, when the slide plate 200 reciprocates, the outlets 201a and 201b can alternately communicate with a pair of adjacent outlets 301, whereby one outlet port 301 of the nozzle plate can be connected. The first raw material outlet 201a and the second raw material outlet 201b can alternately communicate with each other.

  Next, an embodiment of a method for producing a stick food according to the present invention using the stick food production apparatus will be described.

  The first raw material is charged into the hopper 21a, and the second raw material is charged into the hopper 21b. The charged raw material moves under the hopper 21 by its own weight, reaches the raw material outlet 25, and is guided to the receiving port 51 of each pump formed in the case 30. The raw material is pushed into the pump chamber 53 formed by a gap formed between the case 30, the gear 41 and the gear 43, scraped off by the teeth of the gears 41 and 43, and sent to the pump chamber lower portion 55. Since the gear 41 and the gear 43 are fitted, the fed raw material is pushed out from the extrusion ports 39a and 39b.

  Here, since the pump chamber 53 is partitioned by the partition wall 49 and exists corresponding to the extrusion ports 39a and 39b, the pressure of the raw material extruded from the extrusion ports 39a and 39b can be made uniform. The supply pressure of the first raw material and the supply pressure of the second raw material are changed by adjusting the rotational speed of the motor 5 or by adjusting the thickness of the partition wall 49 and the thickness of the gears 41 and 43. You may do it. However, since the bar-shaped food to be manufactured is conveyed by the conveyor 2 at a constant speed, the supply pressure of the first raw material and the second raw material is preferably the same pressure.

  Subsequently, the raw material flows into the grooves 103a and 103b of the deposition plate 100, moves along the grooves 103a and 103b, and is extruded from the extrusion ports 101a and 101b through the holes 105a and 105b.

  Since the first raw material receiving port 203a and the second raw material receiving port 203b formed on the upper surface of the slide plate 200 are arranged below the extrusion ports 101a and 101b so as to be aligned with each other, The raw material extruded from 101b is introduced into the corresponding receiving ports 203a and 203b. In this case, the width of each receiving port 203a, 203b in the reciprocating direction is slightly longer than the sum of the reciprocating width of the slide plate 200 and the diameter of the extrusion ports 101a, 101b. Even if reciprocally moves, the extrusion ports 101a and 101b do not come off the corresponding receiving ports 203a and 203b.

  The raw material introduced into the respective receiving ports 203a and 203b of the slide plate 200 passes through the passage holes 205a and 205b from the first raw material outlet 201a and the second raw material outlet 201b that open on the lower surface of the slide plate 200. leak.

  The first raw material outlet 201a and the second raw material outlet 201b opened on the lower surface of the slide plate 200 are alternately arranged in a line along the reciprocating movement direction at intervals of the reciprocating movement width of the slide plate 200.
