Description

  The present invention relates to a dough producing apparatus for kneading dough materials such as flour and water to form a dough.

  Conventionally, in a bread dough manufacturing apparatus, bread dough is formed by kneading bread dough materials by rotating kneading blades in a container containing bread dough materials such as flour, water, yeast, and the like.

  The container can be formed, for example, in a shell-shaped mortar shape (funnel shape) in which the horizontal cross section is circular and the inner diameter decreases toward the bottom. When the container has such a shape, when the amount of the powder is small, the powder can be kneaded using the vicinity of the bottom having a small volume, and the powder is improved.

  The bread dough manufacturing apparatus provided with said container is disclosed by patent document 1, for example.

JP 2004-254581 A

  When the container has the above shape, a configuration in which a plurality of ribs are provided on the inner peripheral surface of the container can be employed. For example, three ribs protruding inside the container may be provided on the inner peripheral surface of the container.

  FIG. 3 is a view showing a kneading container unit having a container in which three ribs are formed. Fig.3 (a) is a longitudinal cross-sectional view of a kneading | mixing container unit, FIG.3 (b) is BB 'sectional drawing of Fig.3 (a).

  As shown in FIG. 3B, the three ribs are arranged at substantially equal intervals in the circumferential direction. As shown in FIG. 3 (a), each rib extends in the vertical direction along the inner peripheral surface and guides the bread dough rotating in the counterclockwise direction by the stirring action of the kneading blades. Tilt to fall down. Since the rotating dough is pressed downward by the ribs, the weight of the dough can be sufficiently applied to the kneading blade, and the kneading blade can be prevented from coming off due to the kneading blade floating up. Further, when the bread dough is rotated, the outer peripheral portion is hit by a rib. Thereby, since air is contained inside the bread dough, the bread can be baked plumply.

  However, in this configuration, in the region where there is no rib, the outer periphery of the bread dough partially extends outward, but as a whole, the bread dough has the kneading blade as shown by the one-dot chain line in FIG. The center O rotates concentrically. For this reason, bread dough is easy to rotate at the same speed as a kneading blade. In this case, since the kneading blade cannot obtain a sufficient relative speed with respect to the dough, it may happen that sufficient stirring force by the kneading blade is not applied to the dough.

  This invention is made | formed in view of this subject, and it aims at providing the dough manufacturing apparatus which can knead | mix dough favorably with a kneading blade.

  A dough manufacturing apparatus according to a main aspect of the present invention includes a container for storing a dough material, a kneading blade disposed at the bottom of the container, a rotating shaft on which the kneading blade is mounted, and a rotating shaft. A drive motor. Here, the container has a shape in which the horizontal cross section is circular and the inner diameter becomes smaller toward the bottom. A single rib protruding inside the container is formed on the inner peripheral surface of the container, and the rib extends in the vertical direction when viewed from the front.

  According to the above configuration, when the kneading blade rotates, the dough rotates eccentrically with the center thereof deviated from the center of the kneading blade. For this reason, the dough cannot be rotated at the same speed as the kneading blades, and tends to rotate slowly. As a result, the kneading blade can obtain a sufficient relative speed with respect to the dough, so that sufficient stirring force by the kneading blade is applied to the dough and the dough is kneaded well.

  Moreover, since the cloth rotates slowly, the sound when the cloth collides with the rib is reduced. Therefore, the sound generated during kneading can be suppressed.

  Furthermore, since the rib is formed so as to extend in the vertical direction without being inclined with respect to the rotation direction, the rib is unlikely to become an obstacle when taking out the dough from the container. Therefore, the user can smoothly take out the dough from the container.

  In the dough manufacturing apparatus according to this aspect, the rib has a mountain-shaped horizontal cross section by a first side face facing a direction opposite to the rotation direction of the kneading blade and a second side face facing the rotation direction of the kneading blade. Can be formed. In this case, the gradient of the first side surface may be larger than the gradient of the second side surface.

  According to the above configuration, since the gradient of the first side surface can be increased, the fabric can be easily received on the first side surface, and the fabric colliding with the rib can be easily turned over. In addition, since the gradient of the second side surface can be reduced, a deep recess portion is not formed between the second side surface and the inner peripheral surface behind the rib in the rotation direction. Therefore, it is possible to prevent the dough pieces that have been torn off due to the impact when they collide with the ribs from collecting in the indented portion and remain in the indented portion after kneading.

  ADVANTAGE OF THE INVENTION According to this invention, the dough manufacturing apparatus which can knead | mix dough favorably with a kneading blade can be provided.

Is done.

  The upper surface of the casing 100 is covered with a cover (not shown) when the bread dough manufacturing apparatus 1 is not used or is in operation.

  The storage tank 200 is incorporated into the housing 100 from the opening 110 a and attached to the attachment substrate 130. The shape of the storage tank 200 corresponds to the shape of the kneading vessel unit 300, the tank upper part 210 has a cannonball shape, and the tank bottom part 220 has a bottomed cylindrical shape. A bearing 230 is formed at the center of the lower surface of the tank bottom 220. The bearing portion 230 protrudes into the arrangement space S through the hole of the mounting substrate 130. A slide bearing 231 is provided inside the bearing portion 230.

  The kneading vessel unit 300 is housed in the housing tank 200 from above. The kneading vessel unit 300 includes a vessel 310, a bearing case 320, an input rotation shaft 330, and a kneading blade 340.

  The container 310 has a cannonball shape, the horizontal cross section is circular, and the inner diameter becomes smaller toward the bottom. One rib 311 is formed on the inner peripheral surface of the container 310 so as to protrude to the inside of the container 310.

  As shown in FIG. 2A, the rib 311 extends straight in the vertical direction when viewed from the front. As shown in FIG. 2B, the rib 311 is horizontally formed by a first side surface 311a facing in the opposite direction to the rotation direction (counterclockwise direction) of the kneading blade 340 and a second side surface 311b facing in the rotation direction of the kneading blade 340. The cross section is formed in a mountain shape. The rib 311 is formed such that the gradient of the first side surface 311a is greater than the gradient of the second side surface 311b.

  The bearing case 320 has a cylindrical shape whose upper surface is closed and whose lower surface is opened, and is mounted on the outer bottom surface of the container 310 to support the container 310. The bearing case 320 accommodates the shaft coupling 600 therein. A bearing portion 321 is formed on the upper surface of the bearing case 320. The bearing portion 321 protrudes into the container 310 through a hole formed in the bottom surface of the container 310. A slide bearing 322 is provided inside the bearing portion 321.

  The input rotation shaft 330 is rotatably supported by the bearing portion 321. The input rotary shaft 330 has an upper end portion protruding from the bearing portion 321 into the container 310, and a lower end portion protruding from the bearing portion 321 into the bearing case 320.

  The kneading blade 340 is disposed at the bottom of the container 310. The kneading blade 340 is made of resin and includes a boss portion 341 and first and second blades 342 and 343 extending outward from the boss portion 341 on the opposite sides. The kneading blade 340 is attached to the input rotation shaft 330 at the boss portion 341. The kneading blade 340 is placed on the upper surface of the bearing portion 321 and has a predetermined height from the bottom surface of the container 310 to the bottom surface of the kneading blade 340.

  As shown in FIG. 2, the boss portion 341 has a substantially cylindrical shape, and a through hole 341 a into which the upper end portion 331 of the input rotation shaft 330 is inserted is formed in the center portion. The upper end portion 331 of the input rotation shaft 330 is subjected to D-cut processing, and the through hole 341a is formed in a D-shaped cross section in accordance with this. Thereby, the kneading blade 340 is fixed in the rotation direction and cannot rotate with respect to the input rotation shaft 330 in a state where it is attached to the input rotation shaft 330, but is not fixed in the upward direction and is directed upward from the input rotation shaft 330. Can be separated.

  The first blade 342 is integrally formed with the boss part 341 so as to hang downward from the boss part 341, and the lower end of the first blade 342 faces the bottom surface of the container 310. Further, the first blade 342 is inclined at a predetermined angle from the vertical direction so that the front surface of the blade faces slightly upward. Furthermore, the 1st blade | wing 342 has a shape which expands as it goes long downward in the vertical direction.

  The second blade 343 is integrally formed with the boss portion 341 so as to extend substantially horizontally from the boss portion 341. Moreover, the 2nd blade | wing 343 inclines slightly from a horizontal direction so that the rotation direction side may become low.

  The drive motor 400 is attached to the attachment substrate 130 and is disposed on the side of the storage tank 200. The motor shaft 401 of the drive motor 400 protrudes into the arrangement space S through the hole of the mounting substrate 130.

  The drive transmission unit 500 includes an output rotation shaft 510, a large pulley 520, a small pulley 530, and a V belt 540. The output rotation shaft 510 is rotatably supported by the bearing portion 230. The output rotary shaft 510 has an upper end protruding from the bearing 230 into the tank bottom 220 and a lower end protruding from the bearing 230 into the arrangement space S. The large pulley 520 is fixed to the lower end portion of the output rotation shaft 510, and the small pulley 530 is fixed to the motor shaft 401. A V belt 540 is stretched between the large pulley 520 and the small pulley 530.

  The shaft coupling 600 includes a disk-shaped first joint 610 having irregularities formed on the outer peripheral surface and an inverted dish-shaped second joint 620 having irregularities formed on the inner circumferential surface. The first joint 610 is fixed to the upper end portion of the output rotation shaft 510, and the second joint 620 is fixed to the lower end portion of the input rotation shaft 330. When the kneading vessel unit 300 is stored in the storage tank 200, the first joint 610 and the second joint 620 are engaged, and the output rotation shaft 510 and the input rotation shaft 330 are connected.

  Next, operation | movement of the bread dough manufacturing apparatus 1 is demonstrated.

  The user puts an appropriate amount of dough material, that is, an appropriate amount of flour and water, sugar, salt, yeast, etc., corresponding to the amount into the container 310, and presses the operation button 112 for starting operation of the operation unit 111.

  Operation is started and the drive motor 400 rotates. The rotation of the drive motor 400 is transmitted to the input rotary shaft 330, that is, the kneading blade 340 via the drive transmission unit 500 and the shaft coupling 600, and the kneading blade 340 rotates counterclockwise as viewed from above. The rotation speed of the kneading blade 340 is set to 450 rpm to 500 rpm.

  When the kneading blade 340 rotates, the flour containing water and the like is stirred by the first blade 342 and the second blade 343. The flour is mixed with water or the like, and eventually bread dough begins to be formed in the container 310.

  As described above, only one rib 311 is provided on the inner peripheral surface of the container 310. In this configuration, unlike the configuration in which the three ribs described in FIG. 3 are provided, when the kneading blade 340 rotates, the bread dough is kneaded at the center P as shown by the one-dot chain line in FIG. Eccentric rotation is performed in a state of being displaced from the center O of the blade 340. For this reason, the bread dough cannot be rotated at the same speed as the kneading blade 340, and becomes easy to rotate slowly. As a result, the kneading blade 340 can obtain a sufficient relative speed with respect to the bread dough, so that a sufficient stirring force by the kneading blade 340 is applied to the bread dough and the bread dough is firmly kneaded. In addition, when a sufficient stirring force is applied by the kneading blade 340, the dough is turned over well in combination with the collision with the rib 311, and the dough is kneaded uniformly by the kneading blade 340. Furthermore, even if the number of times the ribs 311 are hit is reduced, the air is sufficiently contained in the bread dough by being thoroughly stirred by the kneading blades 340.

  Furthermore, since the dough rotates slowly, the sound when the dough collides with the rib 311 is reduced. Therefore, the sound generated during kneading can be suppressed.

  Furthermore, since the bread dough rotates slowly, even if it comes into contact with the inner front surface of the container 310 having a gradient, it is difficult to lift the inner peripheral surface. Therefore, as described above, the rib 311 can be formed to extend in the vertical direction without being inclined in the direction opposite to the rotation direction. Thereby, when taking out bread dough from the container 310, the rib 311 becomes difficult to get in the way, and the user can smoothly take out bread dough from the container 310.

  Furthermore, the rib 311 is formed so that the gradient of the first side surface 311a is larger than the gradient of the second side surface 311b. Thereby, since the gradient of the first side surface 311a can be increased, it becomes easier to receive the bread dough on the first side surface 311a, and the bread dough that has collided with the rib 311 is easily turned over. In addition, since the gradient of the second side surface 311b can be reduced, a deep hollow portion (indicated by H in FIG. 2B) is formed on the second side surface 311b and the inner peripheral surface behind the rib 311 in the rotation direction. There is no. Therefore, it is possible to prevent the dough pieces that have been torn off due to the impact when they collide with the ribs 311 from collecting in the dent portion and remaining in the dent portion after kneading.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications can be made to the embodiments of the present invention in addition to the above. is there.

  For example, in the above embodiment, the kneading blade 340 is formed of resin. However, the present invention is not limited thereto, and the kneading blade 340 may be formed of a metal such as aluminum. In this case, the surface of the kneading blade 340 is coated with a fluororesin or the like.

  Furthermore, in the above embodiment, the drive transmission unit 500 is provided. However, the present invention is not limited to this, and a configuration may be adopted in which the drive motor 400 is disposed below the storage tank 200 and the shaft coupling 600 is directly connected to the motor shaft 401 of the drive motor 400.

  Furthermore, the bread dough manufacturing apparatus of the above embodiment may be configured to form any noodle dough or pizza dough in addition to bread dough.

  Furthermore, the present invention can be applied to various dough producing apparatuses for forming noodle dough, pizza dough, etc., in addition to the dough producing apparatus for forming dough.
