Description

  The present invention relates to a dough-kneading vertical mixer for kneading dough in a container by a rotary blade rotated by a drive motor.

  As a conventional dough kneading apparatus, a mixer body into which raw materials for noodles are charged, a rotating shaft with a plurality of stirring rods attached to the outer peripheral surface of the mixer body and horizontally disposed on the mixer body, and a rotating shaft are rotated. 2. Description of the Related Art A noodle dough mixer device is known that includes a motor to be driven and a kneading water tray that supplies kneading water into the mixer body.

  In this noodle dough mixer device, the rotating shaft is driven by a motor to rotate the stirring rod while supplying the kneading water from the kneading water tray into the mixer body, so that the raw material of the noodles thrown into the mixer body Are kneaded. Moreover, in this noodle dough mixer device, the bottom of the mixer body is formed in a polygonal shape so that a cut surface cut by a plane perpendicular to the rotation axis follows the rotation trajectory of the stirring rod tip (for example, a patent) Reference 1).

  However, in this noodle dough mixer device, since the mixer body extends in the horizontal direction and the rotating shaft to which a plurality of stirring rods are attached extends horizontally, the kneaded noodle dough is placed on the bottom side of the mixer body. When taking out from the machine, the rotating shaft and the stirring bar tend to get in the way.

  In order to solve this problem, a container with a bottom having a rectangular horizontal cross section and an open upper end, a kneading blade disposed in the bottom of the container, and the kneading blade penetrating through the center of the container are integrated. There is known a kneading cooker provided with a rotating shaft provided and a motor that is disposed outside the container and drives the rotating shaft (see, for example, Patent Document 2).

  In this kneading cooker, a kneading object such as bread dough or noodle dough with water added to the raw material is put into a container, and the kneading object is kneaded with a kneading blade rotating integrally with the rotating shaft, thereby kneading object. Gluten is generated in the product so that the object to be kneaded can be easily taken out from above.

  Embodiments of the present invention will be described below with reference to the drawings.

[Constitution]
FIG. 1 shows a vertical mixer for dough kneading according to the present invention.

  In FIG. 1, 1 is a vertical mixer body (cylindrical kneading container), 2 is a kneading member disposed in the bottom (lower part) of the mixer body 1, and 3 is a rotating shaft for rotating the kneading member 2. Reference numeral 4 denotes a shaft rotation drive device that rotationally drives the rotation shaft 3.

The mixer body 1 is detachably attached to a support frame (support member) such as a frame (not shown) so as not to rotate in the circumferential direction. On this support frame (not shown), a rotating shaft 3 with an axis O directed in the vertical direction is rotatably attached (held) via bearings (bearings) 2a, 2a.
<Mixer body 1>
The mixer body 1 includes a cylindrical body portion 5 whose upper end is opened as a material input port (entrance / exit) 1 a and a bottom wall 6 connected to the lower end of the cylindrical body portion 5.
(Cylindrical trunk 5)
Further, as shown in FIGS. 3 and 4, the cylindrical body portion 5 is formed in a regular polygonal shape from a plurality of plate-like side wall portions 5 a that are integrally provided with an obtuse angle in the circumferential direction. The side wall surface 5a1 is flat (planar) on the inner periphery.
(Bottom wall 6)
Further, as shown in FIG. 4, the bottom wall (bottom part) 6 is formed in an inverted regular polygonal pyramid shape from the plurality of bottom wall parts 6a connected to the plurality of side wall surfaces 5a1 and inclined downward toward the center. Is formed.

A hexagonal mounting hole 6b is formed at the center of the bottom wall 6, and a hexagonal annular body 6c is fitted into the mounting hole 6b. The annular body 6c is integrally attached to the bottom wall 6 by welding or the like. A shaft insertion hole 6d is formed in the annular body (annular plate) 6c. The upper end portion of the rotating shaft 3 penetrating the shaft insertion hole 6d is inserted and disposed in the bottom portion (lower portion) of the mixer body 1 as shown in FIGS. As shown in FIG. 1, a male screw cylinder 7 is fitted to the upper end portion of the rotating shaft 3, and the male screw cylinder 7 is fixed to the upper end portion of the rotating shaft 3 with a set screw (fixing screw) 8.
(Kneading member 2)
The kneading member 2 has a cap nut 9 screwed to the male screw cylinder 7 and a kneading blade (kneading member main body) 10 provided integrally with the cap nut 9. The kneading blade 10 is rotated integrally with the rotary shaft 3 in the clockwise direction indicated by the arrow A1 in FIGS. Moreover, the kneading blade 10 is provided integrally with the cap nut 9 so as to retreat to the opposite side to the rotation direction A1 from the base end (end of the rotating shaft 3 side) toward the tip. In addition, as shown in FIG. 2, the kneading blade 10 is inclined to the side opposite to the rotation direction indicated by the arrow A1 from the lower edge toward the upper edge.

  In this structure, if the rotation locus of the tip of the kneading blade 10 is 11 as shown in FIG. 4, each side wall 5 a and the side wall surface 5 a 1 of the cylindrical body 5 extend in a substantially tangential direction of the rotation locus 11. The cross-sectional shape of the cylindrical body part 5 formed from each side wall part 5a is formed in a regular polygonal shape. The cross-sectional shape of the cylindrical body 5 is formed in a regular 12 polygonal shape in this embodiment, but is not necessarily limited to a regular 12 polygonal shape, but is a regular triangular shape, a regular square shape, or a regular pentagonal shape. Other polygonal shapes are also included. Between the side wall surface 5a1 of the cylindrical body 5 and the rotation locus 11, there is a minimum necessary gap S1 in which the kneading blade 10 can rotate at a portion in the normal direction of the side wall surface 5a1 and the rotation locus 11. It is formed.

Under these conditions, when the dough is moved by the kneading blade 10 in the circumferential direction of the cylindrical body 5, that is, when the dough is moved from the side wall surface 5a1 to the adjacent side wall surface 5a1, A kneading force necessary for generating gluten (gluten structure) can be applied to the kneaded material between the wall surface 5a1. In addition, it is possible to prevent an excessive force from acting on the dough at this time and prevent the gluten structure generated by kneading from being broken.

In the present embodiment, the horizontal cross-sectional shape of the cylindrical body portion 5 is formed in a regular 12 polygonal shape. Under this condition, when the dough is moved by the kneading blade 10 in the circumferential direction of the cylindrical body 5, that is, when the dough is moved from the side wall surface 5a1 to the adjacent side wall surface 5a1, the kneading blade 10 acts on the dough. The force can be reduced as compared with regular polygons (regular triangles, regular tetragons, etc.) in which the angles of the side wall surfaces 5a1, 5a1 are 90 ° or less. Thus, when the angle of the adjacent side wall surfaces 5a1 and 5a1 is an obtuse angle, compared with the regular polygon whose angle of the side wall surfaces 5a1 and 5a1 is 90 ° or less, the tip and side of the kneading blade 10 The kneading force for generating gluten with the wall surface 5a1 can be reduced. Moreover, when the angle of the adjacent side wall surfaces 5a1 and 5a1 is formed as an obtuse angle, the force acting on the fabric is reduced compared to a regular polygon having an angle of the side wall surfaces 5a1 and 5a1 of 90 ° or less. The force acting on the gluten structure of the dough generated by kneading can be reduced. In this case, destruction of the gluten structure of the dough caused by kneading can be prevented more reliably.

  In the present embodiment, as an example in which the angle of the adjacent side wall surfaces 5a1 and 5a1 is formed as an obtuse angle, an example is shown in which the horizontal cross-sectional shape of the cylindrical body 5 is formed into a regular 12 polygonal shape. It is not limited to 12 polygons. For example, if the horizontal cross-sectional shape of the cylindrical body part 5 is a regular pentagon or more, the angles of the side wall surfaces 5a1 and 5a1 can be formed as obtuse angles.

  Further, when the gap between the adjacent portion 5b of the adjacent side wall portions 5a and 5a and the rotation locus 11 is S2, the horizontal cross-sectional shape of the cylindrical body portion 5 is formed in a regular polygonal shape, so that the gap S2 is the gap S1. It gradually increases as it goes from the part to the connecting part 5b.

Here, in FIG. 4, when the rotation locus at a point P having the lower edge of the kneading blade 10 is P11, between the kneading blade 10 and the bottom wall 6, as shown in FIG. A gap S1 ′ similar to the gap S1 is formed between the bottom wall 6a and a gap S2 ′ similar to the gap S2 between the connecting portion of the adjacent bottom walls 6a and 6a and the rotation locus P11. Is formed. The gap S2 'gradually decreases as it goes toward the base end of the kneading blade 10, that is, toward the rotary shaft 3.
<Shaft rotation drive device 4>
As shown in FIGS. 1 and 3, the shaft rotation drive device 4 includes a shaft rotation drive motor 12 fixed to a support frame (not shown), and a rotation that transmits the rotation of the shaft rotation drive motor 12 to the rotation shaft 3. A force transmission mechanism 13 is provided. The rotational force transmission mechanism 13 includes a drive sprocket 14 fixed to the output shaft 12 a of the shaft rotation drive motor 12, a driven sprocket 15 fixed to the rotation shaft 3, and a drive chain 16 stretched over the sprockets 14, 15.

This rotation is transmitted to the rotary shaft 3 via the drive chain 16 and the driven sprocket 15, and the rotary shaft 3 is driven to rotate in the direction of the arrow A1. As a result, the kneading blade 10 in the mixer body 1 is also rotated in the direction of the arrow A1 integrally with the rotary shaft 3.
<Kneaded water tray 17>
As shown in FIG. 1, the material inlet 1 a of the mixer body 1 is closed by a kneading water tray 17 so as to be opened and closed. The kneading water tray (watering tray) 17 is a polygonal shape integrally provided on the outer peripheral surface of the transparent water tray body 18 having a polygonal annular peripheral wall 18a and a bottom wall 18b and the annular peripheral wall 18a of the water tray body 18.

Thereby, the upper surface (reference numeral omitted) of the bottom wall 18b is also inclined downward toward the center of the bottom wall 18b, and is formed in an inverted conical shape.

  Further, the flanges F2 are formed with protrusions 19a and 19b with an interval of 180 °. An engagement shaft 20 extending in the tangential direction of the annular peripheral wall 18a is integrally provided on the protrusion 19a, and a clamp hook 21 is integrally provided on the protrusion 19b.

  On the other hand, as shown in FIGS. 1 and 3, a shaft engaging hook 22 and a catch clip 23 are attached to the outer peripheral surface of the upper end of the cylindrical body 5 at an interval of 180 ° in the circumferential direction.

  As shown in FIGS. 1 and 3, the catch clip 23 has a base 24 fixed to the cylindrical body 5 and an operation in which the upper end of the catch clip 23 is rotatably attached to the base 24 via a support shaft 25a. A lever 25, a telescopic arm 26 that is rotatably attached to the operation lever 25 via a support shaft 26 a and is spring-biased in a contracting direction, and an engagement shaft 27 that is attached to the distal end of the telescopic arm 26. Have. As the structure of the catch clip 23, for example, the same well-known structure as that disclosed in Japanese Patent Application Laid-Open No. 2007-63902 is adopted, and thus detailed description thereof is omitted.

  Then, the annular peripheral wall 18a of the kneading water tray 17 is fitted into the upper end portion of the cylindrical body portion 5, the flange F2 of the annular peripheral wall 18a is placed on the upper end of the cylindrical body portion 5, and the protrusion 19a of the flange F2 is placed. The engagement shaft 20 provided on the shaft is engaged with the shaft engagement hook 22 of the cylindrical body portion 5. On the other hand, with the operating lever 25 of the catch clip 23 pivoted upward about the support shaft 26a, the engagement shaft 27 of the catch clip 23 is engaged with the clamp hook 21 provided on the flange F2 of the water tray 17. Thereafter, the operating lever 25 is rotated downward about the support shaft 26 a, thereby pressing the protrusions 19 a and 19 b of the flange F 2 against the upper end of the cylindrical body 5. As a result, the kneading water receiving tray 17 is detachably fitted to the material charging port 1a, which is the upper opening end of the mixer body 1, so that the material charging port 1a is closed.

  As shown in FIG. 5, a plurality of water guide grooves 28 extending in the radial direction are formed at intervals of 90 ° in the circumferential direction in the middle portion of the inclined bottom wall 18 b of the water tray main body 18.

Further, an intermediate water supply hole (second water supply hole) 30 is formed in the bottom wall 18b on a concentric circle inside the water guide groove 28 and at a position shifted by 45 ° from the water guide groove 28. Further, a central water supply hole (third water supply hole) 31 is formed at the center of the bottom wall 18b.
[Action]
Next, the operation of the dough-kneading vertical mixer configured as described above will be described.

  The material is charged as a kneaded material from the material charging port 1a of the cylindrical body 5. Examples of the kneading material include powder for noodle dough (powder for kneading) such as buckwheat flour and wheat flour, powder such as rice flour, salt and other seasonings, and other materials such as ground vegetables and seaweeds. is there.

  After such a kneaded material is charged into the cylindrical body 5, the kneading water receiving tray 17 is fitted into the material charging port 1a, and the engaging shaft 20 provided on the protrusion 19a of the flange F2 is connected to the cylindrical body. 5 is engaged with the shaft engaging hook 22. On the other hand, with the operation lever 25 of the catch clip 23 pivoted upward about the support shaft 26a, the engagement shaft 27 of the catch clip 23 is attached to the shaft engagement hook 22 provided on the flange F2 of the water tray 17. After the engagement, the operation lever 25 is rotated downward about the support shaft 26 a, thereby pressing the protrusions 19 a and 19 b of the flange F 2 against the upper end of the cylindrical body 5. As a result, the kneading water receiving tray 17 is detachably fitted to the material charging port 1a, which is the upper opening end of the mixer body 1, so that the material charging port 1a is closed.

  Next, the amount of water according to the type of kneaded material put into the cylindrical body 5 and the amount of the kneaded material is put into the water tray body 18. When water is put into the water tray main body 18, the water is caused to flow into the cylindrical body 5 from the water supply holes 29, 30, 31 and the like.

  Accordingly, the shaft rotation drive motor 12 is operated to transmit the rotation of the output shaft 12a of the shaft rotation drive motor 12 to the rotation shaft 3 via the rotational force transmission mechanism 13, whereby the rotation shaft 3 is moved to the arrow in FIG. The kneading blade 10 in the mixer body 1 is also rotated in the direction of the arrow A1 integrally with the rotary shaft 3 by being driven to rotate in the A1 direction. By the rotation of the kneading blade 10, the kneading material charged into the cylindrical body 5 is kneaded by the kneading blade 10 together with the water supplied from the water supply holes 29, 30, 31 and the like.

  During such kneading, the kneading blade 10 rotates the noodle dough kneaded material in the circumferential direction of the cylindrical body 5 while scooping the noodle dough kneaded material upward by the inclined upper surface, and the noodle dough kneaded material is tubed by centrifugal force. The cylindrical body 5 is moved in the radial direction.

  At this time, water is added little by little to the kneaded material, and the mixed material and water are agitated by the kneading blade 10, so that the mixed material gradually becomes a lump. As the kneading progresses, when a necessary amount of water is added to the kneading material powder for noodle dough, the kneading material becomes a large number of masses of the kneaded material for noodle dough.

  A frictional resistance due to viscosity is generated between the lump of the kneaded material for noodle dough and the inner surface of the cylindrical body 5, and between the kneaded material for noodle dough and the inclined upper surface of the kneading blade 10, and kneading for the noodle dough is performed. The lower part side and the cylindrical body part 5 side are kneaded by the kneading blade 10.

Along with this, a part of the kneaded material for noodle dough enters between the kneading blade 10 and the bottom wall 6 due to its own weight, and the kneading blade 10 and the cylindrical body portion 5 are separated by the centrifugal force accompanying the rotation of the kneading blade 10. It is kneaded by dragging in between. However, since there is a narrow gap S1 and a large gap S2 between the kneading blade 10 and the inner surface of the cylindrical body 5, strong and weak forces alternate from the kneading blade 10 to the kneaded material for noodle dough. Act on. Thereby, the gluten of a part of the kneaded material for noodle dough that has entered between the kneading blade 10 and the inner surface of the cylindrical body 5 is generated more quickly. Further, the gluten of a part of the kneaded material for noodle dough that has entered between the kneading blade 10 and the bottom wall 6 is generated more quickly due to the similar gaps S1 'and S2'.

  The flat plate body 41 of the mixer drum punching plate 40 is bent along the folding line 43 as shown in FIG. 7 and the side edges 41a and 41b of the flat plate 41 are joined together by welding or the like. Join. On the other hand, the plurality of bottom plate forming portions 42a are bent inward along the folding curve 44 as shown in FIG. 8, and the side edges of the adjacent bottom plate portions 31 and 31 are joined together by welding or the like. As a result, a cylindrical body plate portion 5 'and a bottom plate portion 6' as shown in FIGS. 9 and 10 are formed. A hexagonal mounting hole 6b is formed at the center of the bottom plate 6 'as shown in FIG. Then, an annular body 6c having a hexagonal outer peripheral surface as shown in FIG. 11 is fitted into the mounting hole 6b as shown in FIG. 12, and this annular body 6c is welded to the bottom plate portion 6 '. Install by.

Since the cylindrical body plate portion 5 'and the bottom plate portion 6' are formed by such a process, the thickness of the bottom plate portion 6 'can be formed to the same thickness as the thickness of the cylindrical body plate portion 5'. The surface of the cylindrical body plate portion 5 ′ and the bottom plate portion 6 ′ thus formed is subjected to surface processing such as wear resistance processing or Teflon processing, so that the cylindrical body portion 5 of the mixer body 1 and A bottom wall 6 is formed.
(Other 2)
In the embodiment described above, the bottom wall 6 is formed in an inverted regular polygonal pyramid shape, but the present invention is not necessarily limited thereto. For example, the bottom wall 6 may be formed in an inverted conical shape (see FIG. 3A).

According to this configuration, the frictional resistance due to viscosity is generated between the lump of the kneaded material for noodle dough and the inner surface of the cylindrical body 5 and between the kneaded material for noodle dough and the inclined upper surface of the kneading blade 10. Since the lower side of the kneaded material for noodle dough and the cylindrical body 5 side are kneaded by the kneading blade 10, a part of the kneaded material for noodle dough enters between the kneading blade 10 and the bottom wall 6 by its own weight. The kneading blade 10 is kneaded by being dragged between the kneading blade 10 and the cylindrical body portion 5 by centrifugal force accompanying the rotation of the kneading blade 10.

The gluten structure generated in the object to be kneaded between the kneading blade 10 and the bottom wall 6 is not destroyed. Therefore, when the cylindrical body 5 and the bottom wall 6 are regular polygons, the kneading object is more uniformly kneaded by the kneading blades than when only the cylindrical body 5 is a regular polygon. Can be shortened.
