The first kneading portion 41 , the second kneading portion 42 and the central shaft portion 43 are integrally connected by two supporting members 44 , 44 provided extending in parallel in the diametrical direction of the body portion 31 .

As shown in FIGS. 5 to 7, the first kneading portion 41 and the second kneading portion 42 have different shapes in plan view, and as shown in FIGS. The shape in the direction along the axis C) is also different from each other.

As shown in FIG. 7, the first kneading section 41 is longer than the second kneading section 42 in the direction of rotation of the kneading blade 40 in plan view. As shown in FIG. 5, the first kneading part 41 is a front side portion (a side closer to the tip 41c than the rear end 41d) in the clockwise rotation direction R of the kneading blade 40 (hereinafter referred to as a front portion 41a). , the rear side of the clockwise rotation R (the side closer to the rear end 41d than the leading end 41c) (hereinafter referred to as the rear side portion 41b).

Specifically, as shown in FIGS. 5 and 8, the lower surface 41f of the front portion 41a is formed in a substantially horizontal horizontal plane from the vicinity of the tip 41c to the boundary 41e with the rear portion 41b. On the other hand, the lower surface 41g of the rear portion 41b is formed as an inclined surface that is uniformly inclined with respect to the horizontal plane, gradually lowering continuously from the boundary 41e with the front portion 41a toward the vicinity of the rear end 41d. there is

Here, the inner surface 32a of the bottom plate 32 of the container 30 is inclined so that it becomes higher as the radial distance from the axis C increases. Therefore, the distance between the lower surface 41f of the front portion 41a and the inner surface 32a is the widest at positions near the axis C, and becomes narrower as the distance from the axis C increases in the radial direction.

On the other hand, the distance between the lower surface 41g of the rear portion 41b and the inner surface 32a becomes narrower with distance from the axis C in the radial direction, and also narrows from the boundary 41e toward the vicinity of the rear end 41d. .

On the other hand, the lower surface 42g of the second kneading portion 42, which is smaller than the first kneading portion 41 in plan view, is located near the tip 42c, which is the front side in the clockwise rotation direction R of the kneading blade 40, as shown in FIGS. As it approaches the vicinity of the rear end 42d, which is the rear side in the rotation direction, it is gradually lowered continuously downward, and is formed as an inclined surface that is uniformly inclined with respect to the horizontal plane.

Therefore, the distance between the lower surface 42g of the second kneading portion 42 and the inner surface 32a of the bottom plate 32 of the container 30 becomes narrower as it becomes more distant in the radial direction from the axis C, and approaches from near the tip 42c to near the rear end 42d. It also becomes narrower.

Here, the inner surface 32a of the bottom plate 32 of the container 30 is inclined so that it becomes higher as the radial distance from the axis C increases. Therefore, the distance between the lower surface 41f of the front portion 41a and the inner surface 32a is the widest at positions near the axis C, and becomes narrower as the distance from the axis C increases in the radial direction.

The radial outer peripheral surface 41h of the first kneading portion 41 and the radial outer peripheral surface 42h of the second kneading portion 42 are shown in FIG. , is formed in an arc shape in a plan view, substantially along the inner surface 31a of the body portion 31 of the container 30. As shown in FIG.

<Action>
In the kneading machine 100 for buckwheat dough 200 according to the present embodiment configured as described above, the rotating shaft 12 protrudes into the container 30 in a state where the container 30 is arranged in the container placement portion 15 of the driving portion 10 . The central shaft portion 43 of the kneading blade 40 is fitted to the rotating shaft 12 projecting inside the container 30 , and the kneading blade 40 is arranged at the bottom of the container 30 . When the central shaft portion 43 is fitted to the rotating shaft 12 , the hole 33 of the bottom plate 32 is closed by the central shaft portion 43 .

As shown in FIG. 3, a predetermined amount of buckwheat dough 200 is put into the container 30 with the lid 50 removed. The buckwheat dough 200 to be put into the container 30 is a mass of kneaded material in which water is evenly added to the buckwheat flour and the water permeates the buckwheat flour to form a sticky semi-solid form. The container 30 into which the buckwheat dough 200 is put is covered with a lid 50 to close the upper end opening of the container 30 (FIG. 1).

The rotating shaft 12 of the drive unit 10 rotates clockwise R, and the kneading blade 40 fitted to the rotating shaft 12 rotates clockwise R about the axis C inside the container 30 as shown in FIG. Since the container 30 does not rotate at this time, the kneading blade 40 rotates relative to the container 30 .

A lump of buckwheat dough 200 put into the container 30 is put on and in contact with the inner surface 32a of the bottom plate 32, and is kneaded by the kneading blades 40 rotating above the bottom plate 32, as shown in FIGS. , between the inner surface 32a of the bottom plate 32 and the lower surface 41f of the front portion 41a of the first kneading portion 41, or as shown in FIG. sandwiched between

The buckwheat dough 200 sandwiched between the inner surface 32a of the bottom plate 32 and the lower surface 41f of the first kneading section 41 is in a state where the lower portion contacts and adheres to the inner surface 32a and the upper portion contacts and adheres to the lower surface 41f. Due to the rotation of the first kneading unit 41, the inner surface 32a to which the lower portion of the buckwheat dough 200 is attached and the lower surface 41f to which the upper portion of the buckwheat dough 200 is attached are moved away from each other in the circumferential direction. is stretched so as to be sheared in the circumferential direction between

As the kneading blade 40 rotates, a slip occurs between the lower surface 41f and the upper portion of the buckwheat dough 200, and the lower surface 41f slides on the upper portion of the buckwheat dough 200 and moves forward in the rotational direction. In addition, slippage occurs little by little between the inner surface 32a and the lower portion of the buckwheat dough 200.例文帳に追加As a result, the buckwheat dough 200 moves little by little in the rotation direction of the kneading blade 40 as a whole. The moving speed of the buckwheat dough 200 in the circumferential direction is slower than the moving speed of the first kneading section 41 in the circumferential direction due to the rotation of the kneading blades 40 .

The lower surface 41f of the front portion 41a moves away from the upper portion of the buckwheat dough 200, but due to the rotation of the kneading blade 40, the rear portion 41b following the front portion 41a moves to the upper portion of the buckwheat dough 200, as shown in FIG. , the lower surface 41g of the rear portion 41b contacts and adheres to the upper portion of the buckwheat dough 200. As shown in FIG. As a result, the buckwheat dough 200 is sandwiched between the inner surface 32 a of the bottom plate 32 and the lower surface 41 g of the rear portion 41 b of the first kneading section 41 .

The buckwheat dough 200 sandwiched between the inner surface 32a of the bottom plate 32 and the lower surface 41g of the first kneading section 41 is in a state in which the lower portion is in contact with the inner surface 32a and the upper portion is in contact with the lower surface 41g. , the lower surface 41g of the rear portion 41b is slanted so that the distance from the inner surface 32a becomes shorter as it approaches the rear end 41d. The buckwheat dough 200 sandwiched between the two is pressed from the lower surface 41g as the first kneading section 41 moves forward (rotates in the rotational direction).

In this way, the buckwheat dough 200 is strongly kneaded by receiving the compressive force due to the shearing force and pressure from the bottom plate 32 and the rotating first kneading unit 41 .

As the kneading blade 40 rotates, a slip occurs between the lower surface 41g and the upper portion of the buckwheat dough 200, and the lower surface 41g slides on the upper portion of the buckwheat dough 200 and moves forward in the rotational direction. In addition, slippage occurs little by little between the inner surface 32a and the lower part of the buckwheat dough 200.例文帳に追加As a result, the buckwheat dough 200 as a whole gradually changes its posture so as to move or roll in the rotation direction of the kneading blade 40 . The moving speed of the buckwheat dough 200 in the circumferential direction is slower than the moving speed of the first kneading section 41 in the circumferential direction due to the rotation of the kneading blades 40 .

Although the first kneading unit 41 leaves the buckwheat dough 200, the rotation of the kneading blade 40 moves the second kneading unit 42 following the first kneading unit 41 to the upper part of the buckwheat dough 200 as shown in FIG. , the lower surface 42g of the second kneading unit 42 contacts and adheres to the upper portion of the buckwheat dough 200. As shown in FIG. As a result, the buckwheat dough 200 is sandwiched between the inner surface 32 a of the bottom plate 32 and the lower surface 42 g of the second kneading section 42 .

The buckwheat dough 200 sandwiched between the inner surface 32a of the bottom plate 32 and the lower surface 42g of the second kneading section 42 is in a state in which the lower portion is in contact with the inner surface 32a and the upper portion is in contact with the lower surface 42g. , the lower surface 42g of the second kneading section is slanted so that the distance from the inner surface 32a becomes shorter as it approaches the rear end 42d. The buckwheat dough 200 sandwiched between the two is pressed from the lower surface 42g as the second kneading section 42 moves forward (rotates in the rotational direction).

In this way, the buckwheat dough 200 is strongly kneaded by receiving a compressive force due to shearing force and pressure from the bottom plate 32 and the rotating second kneading unit 42 .

As long as the kneading blades 40 continue to rotate, the buckwheat dough 200 is alternately and strongly kneaded by the first kneading section 41 and the second kneading section.

Moreover, the bottom plate 32 has a shape in which the slopes of the truncated pyramid are arranged upside down. , changes periodically in the circumferential direction about the axis C. As shown in FIG.

That is, since the bottom plate 32 is an inclined plane of a truncated dodecagonal pyramid, the distance between the inner surface 32a of the bottom plate 32 and the lower surface 41f or 41g of the first kneading section 41 or the lower surface 42g of the second kneading section 42 is the axis C It changes 12 times during one rotation. Due to the change in this distance, the shearing force acting on the buckwheat dough 200 and the compressive force due to pressure change periodically.

Furthermore, the inner surface 32a of the bottom plate 32 is inclined so that the height in the vertical direction (direction along the axis C) increases as the distance in the radial direction from the axis C increases. As the directional distance increases, the gap between the inner surface 32a of the bottom plate 32 and the lower surface 41f or 41g of the first kneading section 41 or the lower surface 42g of the second kneading section 42 narrows.

As a result, the buckwheat dough 200 sandwiched between the inner surface 32a of the bottom plate 32 and the lower surface 41f or 41g of the first kneading section 41 or the lower surface 42g of the second kneading section 42 changes its position in the radial direction. Also, the compressive force and shear force received from the inner surface 32a and the lower surfaces 41f, 41g, and 42g change.

As described above, due to the rotation of the kneading blade 40, the buckwheat dough 200 is subjected to a compressive force and a shearing force that constantly change during one rotation of the kneading blade 40, so that the buckwheat dough 200 is evenly and more uniform. The buckwheat dough 200 is thoroughly kneaded and the air mixed in the buckwheat dough 200 is removed. As a result, the buckwheat dough 200 is kneaded evenly, more uniformly, and sufficiently, like kneading by a skilled craftsman.

The buckwheat dough kneading machine according to the present invention is not limited to kneading the buckwheat dough of 100% buckwheat noodles that does not use any binders at all, but is used for buckwheat dough that uses binders such as nihachi soba. It may be the object of kneading.
