Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing food dough such as confectionery and bread, and more particularly to an apparatus for quantitatively discharging food dough in a uniform ring shape or the like.

[0002]

2. Description of the Related Art Conventionally, as a method for producing wrapped foods represented by anpan, bun, strawberry Daifuku, etc., a method of continuously discharging a bar-shaped dough having a concentric double structure and cutting the wrapped food is generally known. In order to continuously produce wrapped foods having the same weight and shape, it is a prerequisite for continuous production to stably produce a continuous rod-shaped dough having a double structure. As a conventional example of a method for producing a uniform double bar-shaped dough, there is the following method. For example, JP-A-63-209574 (conventional example 1)
Discloses an invention relating to an apparatus for manufacturing chestnut buns in which solid foods such as chestnuts are coated with confectionery dough, and in order to uniformly shape the confectionery dough covering the solid foods into a cylindrical shape,
A flow adjustment knob is provided to regulate the flow of the confectionery dough. That is, in deforming the cylindrical dough into a cylindrical shape,
The flow rate of the confectionery material is regulated by providing a narrow portion and a wide portion of the flow path width by a flow adjustment knob for the dough flow difference in the deformation process.

[0003] In addition, in the above-mentioned conventional example 1, the coated product is made 1
Although the case of manufacturing individually is shown, in the case of mass production, a plurality of outlets will be provided, and in this case, it is necessary to further uniformly feed the food material itself to be sent to each outlet . As a method for making the dough feed amount uniform for each discharge port when a plurality of discharge ports are provided, for example, there is JP-A-57-186482 (conventional example 2). The conventional example 2 is an apparatus for manufacturing a product coated with bean paste with bean paste in three rows, and it is necessary to supply a fixed amount of branch feed from one place to three places. Therefore, in the conventional example 2, the coating material, Habuchi mochi, is once fed by pressure to the main material distribution chamber by a roll gear, branched and supplied to each die from the main material distribution chamber at a constant pressure, and discharged in a cylindrical shape. However, in actuality, the discharge pressure differs due to wall resistance and the like, and discharge cannot be performed uniformly from three places. Therefore, a ladder plate is provided in the distribution chamber, and the angle of the ladder plate is controlled by adjusting the knob. The method of balancing the discharge amount of each die by adjusting the flow of the main material is shown.

[0004] However, the method shown in the prior art 1 is effective when only fluid dough is sent out, but has a problem with dough such as soybean Daifuku containing solid matter. Was. That is, in order to narrow the width of the flow path where the flow rate of the confectionery dough is large, there has been a problem that solids in the dough are clogged in the narrow flow path. In the case of performing production in a plurality of rows, it is necessary to adjust the balance of the entire row at the same time as the adjustment of each discharge device. In the method of the first conventional example and the method of the second conventional example, an adjustment knob and a knob are used. Therefore, the determination of the adjustment order and the adjustment amount requires more steps and skill than expected, and the long-term adjustment work after cleaning, which is performed regularly, has been a major problem. Therefore, especially at the present time when the number of rows increases, an alternative to the conventional method has been urgently desired.

[0005]

Therefore, according to the present invention, in producing concentric rod-like dough or hollow rod-like dough using a food material as a core material, a uniform cylindrical shape is discharged without regulating a flow path. It is an object of the present invention to provide a device capable of performing such operations. Further, in an apparatus having a multi-row discharge port device,
It is another object of the present invention to provide a device that simplifies an adjustment operation for each discharge port and can reduce a burden on an operator.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an inner nozzle and an outer nozzle having different diameters are overlapped on the same axis to form an annular gap between the outer nozzle and the inner nozzle. A food dough discharge device that discharges a skin material from an inner nozzle end,
Or / and outer nozzle end (inner nozzle end,
At least one of the outer nozzles is made movable in the axial direction to adjust the degree of overlap between the inner nozzle end and the outer nozzle end. This changes the pressure required for discharge by changing the length of the overlapping portion between the inner nozzle end and the outer nozzle end that is the discharge port of the outer material,
The pressure of the outer skin material to be discharged is adjusted.

It is desirable that the inner nozzle is provided so as to discharge a food material, for example, a fluid dough or a lump-shaped material as an inner packaging material. Thereby, a food dough having an inner wrapping material wrapped with a uniform outer wrapping material can be provided.

Further, by providing a plurality of discharge devices in one food dough supply device, the pressure in each discharge device is adjusted simultaneously with the pressure in the discharge device.

The polymerization nozzle 8 is provided with four removable ejection devices 13 including an inner nozzle 11 and an outer nozzle 12. The inner nozzle 11 is a nozzle for discharging the inner material, and is attached to the inner material passage 9 of the polymerization nozzle 8. The cylindrical inner nozzle 11 has a constant diameter length A following a tapered portion tapered toward the lower end in order to increase the discharge pressure.
The inner nozzle end 14 is formed. The outer nozzle 12 is a ring-shaped member that forms a cylindrical outer material passage 15 between the outer nozzle 12 and the inner nozzle 11.
5 is continuous from the skin material passage 10 of the polymerization nozzle 8.
The outer nozzle 12 is detachable from the polymerization nozzle 8 by a fastener 16.

An outer skin passage 15 continuous with the outer skin passage 10
A ring-shaped moving ring 19 that is movable in the axial direction is provided at the end of the outer nozzle 12 that forms the ring. The moving ring 19 is provided on the annular edge 18 of the outer nozzle 12.
Into the outer nozzle 12

In order to fix the mounting position of the moving ring 19, a lock nut 23 is provided on the screw portion 21. Reference numeral 24 denotes a wrapping cutting block of a shutter mechanism that wraps and cuts the continuously discharged double bar-shaped dough. A conveyor 26 that conveys wrapped food 25 is provided below the wrapping cutting block 24.

(Second Embodiment) In a second embodiment, the inner nozzle end, which is the discharge end of the inner packaging material described in the first embodiment, is also movable in the axial direction. This is an example in which both nozzle ends are adjusted to be movable in the axial direction. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In order to enable the inner nozzle 11B to move up and down, the polymerization nozzle 8B is provided with an inner material passage 9 and an outer material passage 10 which are continuously provided in the respective transport pipes 6, and also passes through the inner nozzle 11B. Slidably provided. The cylindrical inner nozzle 11B has an inner material passage 9B from a connection port 27 continuous with the inner material passage 9 of the polymerization nozzle 8B to the inner nozzle end 14, and the connection port 27 is longer than the inner material material passage 9. The length of the inner nozzle 11B is arbitrarily determined by the amount of movement of the inner nozzle 11B in the axial direction. Inner nozzle 11B
Is supported by a key-shaped stand 28 having an adjuster 29 provided on the upper side thereof attached to the side surface of the transport pipe 6. The adjuster 29 is provided with a handle 30, a shaft 31 provided with a thread around it, and an arm 32 whose lower part is fitted to the inner nozzle in the same axis in series. The shaft 31 is provided near the tip of the stand 28. Screw holes.

(Operation and Effect of First Embodiment)
The outer shell material is uniformly supplied to the polymerization nozzle 8 by the screw 3 and the fixed-rate supply pump 7. In the polymerization nozzle 8, the inner packaging material and the outer skin material are branched to each discharge device 13, the inner packaging material is transported to the inner nozzle 11, and the outer skin material is transported to the moving ring 19 through the outer skin material passage 15 of the outer nozzle 12. Finally, the inner material is discharged from the inner nozzle end 14 in a cylindrical shape, and the outer material is discharged from the outer nozzle end 22 in a cylindrical shape centering on the inner material, thereby forming and discharging a double rod-shaped material.

If the outer skin material is not uniform in thickness, the moving ring 19 is advanced into the outer nozzle 12 so that the overlapping portion M (the overlapping degree of A and B) between the inner nozzle end 14 and the outer nozzle end 22 is reduced. It can be long. As a result, the pressure value required for discharging the outer skin material is increased, and the circumference of the skin inside the moving ring 19 is improved, so that the outer skin material can be finally discharged uniformly. Therefore, since the passage 15 of the outer skin material has a constant width,
Even when the outer material contains solids, there is no problem such as solid material being clogged, and the range of materials that can be used for the outer material is expanded,
The device became more versatile.

Even if the discharge pressure balance of each of the four discharge devices 13 is poor and the weight of the wrapped product 27 is irregular, the weight of the moving ring 19 can be adjusted by moving the four moving rings 19 forward and backward. Invasion was prevented. That is, by moving at least one moving ring forward and backward, the skin material pressure in each ejection device 13 is balanced in pressure through each polymerization nozzle 8 and the common passage 6, and the pressure of each ejection device 13 is easily adjusted. The discharge amount could be adjusted to be constant.

(Operation and Effect of Second Embodiment) Handle 3
By rotating 0, the shaft 31 screwed with the stand 28 moves up and down with respect to the stand 28,
At the same time, the inner nozzle 11B that freely engages with the arm 32 provided below the shaft 31 moves up and down. Therefore, the inner nozzle end 14 and the outer nozzle end 2
2 can be adjusted by the vertical movement of the inner nozzle end 14 in addition to the movement of the outer nozzle end 22. Therefore, the present embodiment has the outer nozzle end 2 in addition to the functions and effects of the first embodiment.
When the adjustment cannot be made due to the mounting condition of 2, the adjusting means becomes an alternative means, and since both can be moved together, the adjustment range becomes large.

As another embodiment, in the case of manufacturing hollow confectionery, bread and the like, for example, the hopper 2B of the inner packaging material is used.
A means for preventing the dough from being fed from the hopper, the hopper 2B, the transport pipe 6 connected to the hopper 2B, and the metering supply pump are removed, and a cover or the like is provided at the inner material passage entrance of the polymerization nozzle 8 to discharge only the outer material in a cylindrical shape. It becomes possible to manufacture. Also,
Chestnuts, strawberries, chocolate, not liquid food ingredients
By discharging bulk food materials such as meat dumplings from the inner nozzle, it is possible to manufacture, for example, a strawberry daifuku mochi or a chestnut bun containing the bulk food materials in an outer skin material. The number of ejection devices is not limited, and the effects of the present invention can be obtained with one or more ejection devices. Although the screw is provided in the horizontal direction, it can be provided in the vertical direction.If the dough does not move in the horizontal direction or the dough itself is easy to flow due to the fluidity of the dough, for example, the quantitative May not require a feed pump. The movement of the inner nozzle and the moving ring in the axial direction of the present embodiment is performed manually,
For example, although the size of the machine is increased, it is within the scope of the design change that the servo motor can be used to quantitatively fine-tune the computer remotely from a remote location or that the storage function can improve the reproducibility.

[0019]

As described above, the present invention provides an apparatus for discharging food dough in which an inner nozzle and an outer nozzle having different diameters are overlapped on the same axis, and a skin material is discharged from an annular gap between the outer nozzle and the inner nozzle. In the above, the end portion of the outer nozzle or / and the end portion of the inner nozzle can be moved in the axial direction to adjust the degree of overlap between the inner nozzle end and the outer nozzle end, so that the cloth is formed between the outer nozzle and the inner nozzle. It has become possible to discharge uniform cylindrical food dough around the annular gap uniformly. Further, there is no need to regulate the flow path as in the conventional means, and even when the dough contains solids such as chestnuts and beans, the solids do not clog the flow path, and the device has high versatility.

Further, by providing the inner nozzle such that fluid food dough such as jam or bean jam or a lumpy food material such as fruit, meat, cheese or the like is ejected from the inner nozzle as an encapsulating material, the commercial value of the product is reduced. It has become possible to discharge food dough quantitatively to produce high foreskin foods.

Further, by providing a plurality of discharge devices in one food dough supply device, the product weight disturbance caused by the difference in pressure balance between the discharge devices can be reduced by the end of one of the outer nozzles. The pressure balance can be adjusted by adjusting the length of the nozzles, and the discharge amount from each discharge device can be made constant. Since the device according to the present invention has fewer adjustment points compared to the conventional device, the balance adjustment is greatly reduced, the adjustment after cleaning performed on a regular basis is much easier than in the past, and the utilization rate of the device is greatly increased. At the same time, it is possible to reduce the work load on the workers and the like. This is very effective when the size of the apparatus is increased.
