In addition, although the state where the sesame dumpling D is conveyed in the state where it arranged in 2 rows is shown by the conveyor part 51, it is not restricted to this, You may make it convey in 1 row.

  The dumpling rotating unit 52 includes a housing 53, a lid body 54, a first screw 55, a second screw 56, a first driving unit 57, and a second driving unit 58. The dumpling rotating unit 52 conveys the sesame dumpling D in the Y direction while forming the sesame dumpling D into a spherical shape by rotating it in a spiral shape.

  The casing 53 is formed to be long in the Y direction. The housing 53 has a carry-in port 53a and a carry-out port 53b for the sesame dumpling D. The carry-in port 53 a is provided at the −Y side end of the housing 53. The carry-in port 53 a carries in the sesame dumpling D supplied from the conveyor unit 51. The carry-out port 53 b is provided at the end portion on the + Y side of the housing 53. The carry-out port 53b carries out the sesame dumpling D after molding. The lid 54 is disposed on the + Z side of the housing 53 and is provided so as to be opened and closed.

  The first screw 55 and the second screw 56 are accommodated in the housing 53. The first screw 55 and the second screw 56 hold the sesame dumpling D with two. The first drive unit 57 rotates the first screw 55. The second drive unit 58 rotates the second screw 56. As the first drive unit 57 and the second drive unit 58, for example, a motor device or the like can be used.

FIG. 2A and FIG. 2B are diagrams showing configurations of the first screw 55 and the second screw 56. 2A is a diagram when viewed from the + Z side in the −Z direction, and FIG. 2B is a diagram when viewed from the −Y side in the + Y direction.
As shown in FIGS. 2 (a) and 2 (b), the first screw 55 is formed longitudinally in the Y direction and is provided so as to be rotatable in the θY direction around a rotation axis AX1 parallel to the Y axis. It has been. The first screw 55 has a groove 55b formed in a spiral shape in the Y direction. The groove 55b is formed so that the cross-sectional shape passing through the rotation axis AX1 is a semicircular shape. A thread 55a is formed between the grooves 55b in the Y direction. The screw thread 55a is formed with a sharp tip.

  The second screw 56 is formed longitudinally in the Y direction, and is provided so as to be rotatable in the θY direction around a rotation axis AX2 parallel to the Y axis. The second screw 56 has a groove 56b formed in a spiral shape in the Y direction. The groove portion 56b is formed so that a cross-sectional shape passing through the rotation axis AX2 is a semicircular shape. A thread 56a is formed between the grooves 56b in the Y direction. The screw thread 56a is formed with a sharp tip.

  The first screw 55 and the second screw 56 are formed to have the same shape, the same size, and the same material. For example, the first screw 55 and the second screw 56 are formed using ultra high molecular polyethylene. Since the material has high density and fine particles, the surface can be finished smoothly. In addition, the material has an advantage that it is difficult to absorb moisture and absorb water and is resistant to thermal expansion.

  Moreover, the dimension of the Y direction of the 1st screw 55 and the 2nd screw 56 is about 500 mm. Moreover, the pitch P (corresponding to the radius of the groove 55b) of the threads 55a and 56a in the Y direction can be set as appropriate depending on the diameter of the sesame dumpling D. For example, when a 30 g sesame dumpling is molded, since the diameter is about 40 mm, the pitch P can be set to about 42 mm. In addition, when molding a 25g sesame dumpling, since the diameter is about 30 mm, the pitch P can be set to about 32 mm. The above values are merely examples, and other dimensions can be set.

  The first screw 55 and the second screw 56 are arranged side by side in the X direction. The first screw 55 and the second screw 56 are arranged so that the screw threads (the screw thread 55a and the screw thread 56a) face each other. For this reason, the second screw 56 is disposed on the + Y side with respect to the first screw 55. Further, with this configuration, the groove portion 55b and the groove portion 56b face each other. The first screw 55 and the second screw 56 are arranged so that the distance S between the bottoms of the groove 55b and the groove 56b facing each other is about 30 mm.

  As shown in FIG. 2B, the second screw 56 is disposed on the + Z side with respect to the first screw 55. A straight line connecting the rotation axis AX1 of the first screw 55 and the rotation axis AX2 of the second screw 56 is inclined by an angle θ (eg, 30 °) with respect to the X axis.

  Moreover, the 1st screw 55 and the 2nd screw 56 have the connection parts 55c and 56c. The connecting portions 55c and 56c are held by a bearing (not shown). Further, the + Y side connection portions 55c and 56c are connected to the first drive portion 57 and the second drive portion 58, respectively.

Next, a method for manufacturing sesame dumplings using the dumpling manufacturing system 100 configured as described above will be described.
First, use a mixer to create a dumpling dough. The composition of the dough is not particularly limited. In this embodiment, a soft dough or starchy dough is used. Next, the wrapping unit 10 wraps it using the dough. A dumpling having a partly sharp shape is discharged from the wrapping portion 10.

  Next, sesame (granular material) is applied to the surface of the dumpling in the granular material adhering portion 20. In addition, in this process, in order to prevent the sesame dumpling D from sticking to a part of the molding part 50 (the first screw 55, the second screw 56, etc.) in the later molding process, in addition to sesame, flour (such as wheat flour) ) And so on.

Next, the sesame dumpling D is supplied from the dumpling supply unit 30 to the conveyor unit 51.
Two dumpling supply units 30 may be provided. In this case, two rows of sesame dumplings D supplied to the conveyor unit 51 are formed by two supply systems, and the sesame dumplings D are efficiently supplied.

  The sesame dumplings D transported in the + Y direction by the conveyor unit 51 to the dumpling rotating unit 52 are carried from the carry-in port 53a of the housing 53. The sesame dumpling D carried into the casing 53 is disposed between the first screw 55 and the second screw 56.

FIGS. 3A and 3B are views showing a state of the molding operation of the sesame dumpling D in the dumpling rotating section 52. FIG. 3A is a diagram when viewed from the + Z side in the −Z direction, and FIG. 3B is a diagram when viewed from the −Y side in the + Y direction.
As shown in FIG. 3A, the sesame dumpling D carried into the housing 53 from the carry-in port 53a is sent to the initial position ST. The initial position ST is the position closest to the −Y side between the groove 55b and the groove 56b facing each other.

  Since the threads of the first screw 55 and the second screw 56 (threads 55a, 56a) face each other and the groove parts (groove parts 55b, 56b) face each other, the sesame dumpling D arranged at the initial position ST is 3 (a) and 3 (b), it is held between the groove 55b and the groove 56b (holding step).

  In addition, the 1st screw 55 and the 2nd screw 56 are made into the state rotated beforehand. Specifically, as shown in FIG. 3B, when viewed in the + Y direction, the first screw 55 and the second screw 56 are rotated clockwise. The sesame dumpling D arranged at the initial position ST rotates while being on the first screw 55 and supported by the second screw 56. As the first screw 55 and the second screw 56 rotate, the sesame dumpling D rotates in a spiral shape and is rounded by the rotation (molding step).

  As the first screw 55 and the second screw 56 rotate, the sesame dumpling D rotates while being held between the groove 55b and the groove 56b, and is conveyed in the Y direction. In addition, since the sesame dumplings D are coated on the surface of the sesame dumpling D, it is suppressed that the sesame dumpling D adheres to the 1st screw 55 or the 2nd screw 56. The sesame dumpling D is rounded by the centrifugal force of its own rotation, and the surface becomes hard to the extent that it cannot be tightened. In addition, a part of the sesame seeds that are applied to the surface of the sesame dumpling D is appropriately kneaded into the dumplings, and is difficult to come off in the subsequent steps.

  The sesame dumpling D that has reached the + Y side ends of the first screw 55 and the second screw 56 is discharged from the carry-out port 53 b of the housing 53. The discharged sesame dumpling D is separately cooked in a cooking device such as oil frying and steaming, and then frozen, for example.

  As described above, according to the present embodiment, the dumpling (sesame dumpling D) to which the granular material is attached is held by the first screw 55 and the second screw 56, and the sesame is added by the first screw 55 and the second screw 56. Since the sesame dumpling D is rolled by rotating the dumpling D in a spiral shape, it is possible to mold the sesame dumpling D while fixing the sesame to the sesame dumpling D without requiring manual work of a skilled craftsman. As a result, productivity can be improved.

The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention.
