【Example】
Embodiments of the present invention will be described below with reference to the drawings. 1 to 4, the rotational output of the electric motor 2 built in the main body 1 is decelerated to the main shaft 7 supported by the bearing 6 through the small pulley 3, the belt 4, and the large pulley 5 to transmit power. The kneading blade 8 pivotally supported by the main shaft 7 is rotated to stir and knead the ingredients of the ingredients such as bread, pizza and the like in the container 9 such as flour, water, butter and salt. The kneading blade 8 includes a substantially cylindrical shaft portion 10 and three upper blades 11, middle blades 12, and lower blades 13 provided at different heights of the shaft portion 10 and extending in a substantially radial direction. . Raw materials for ingredients such as bread and pizza are subjected to a kneading operation on the raw materials combined by solid mixing and solid mixing by the rotational movement of the upper blade 11, middle blade 12 and lower blade 13, and the integrated raw materials by powder mixing. Gluten is generated in the dough and the bread dough / pizza dough 14 is completed. The upper blade 11, the middle blade 12, and the lower blade 13 are provided on the shaft portion 10 at an equal allocation angle of 120 degrees. A lid 15 covers the container 9 from above.
[0010]
When the dough is kneaded, the upper blade 11, the middle blade 12, and the lower blade 13 are provided on the shaft portion 10 at an equal allocation angle of 120 degrees, so that any of the blade portions always receives a load force from the dough. Become. Thereby, the fluctuation | variation of the load force from the dough received during one rotation of the kneading blade 8 becomes small. Therefore, the vibration and noise of the equipment during operation can be suppressed, and it is possible to prevent the user from feeling uncomfortable and the equipment moves violently on the installation surface, for example, when the equipment is placed on a table. Can be prevented from falling from the table and being damaged.
[0011]
Further, as shown in FIG. 3, the blades of the shaft portion 10 have the uppermost upper blade 11 having a smaller diameter and the lowermost lower blade having a larger diameter. This makes it possible to quickly collect the semi-mixed ingredients of the highly sticky powder and water that stay and adhere to the bottom of the container during powder matching and form them into dough dumplings quickly and with a large lower blade. Can be quickly transferred to the kneading process. Moreover, since it can prevent that a foodstuff remains on a container bottom face part, the washing | cleaning of the container after use of an apparatus is also easy without wasting foodstuff. In addition, since the upper blade 11 of the uppermost stage has a small diameter, the load received from the dough is small, and the load force received by the kneading blade 8 as a whole can be reduced, so that vibration and noise of the operating equipment can be suppressed. The output of the electric motor 2 can be reduced. Therefore, the electric motor 2 can use a small thing by design, can make the whole apparatus compact, and usability and storage property improve.
[0012]
Further, as shown in FIG. 2, the blades of the shaft portion 10 are provided at heights that are sequentially raised with respect to the rotational direction in the order of the upper upper blade 11, the middle middle blade 12, and the lower lower blade 13. Yes. As a result, the blade contacts the fabric in the order of the upper blade 11, the middle blade 12, and the lower blade 13 with respect to the fabric 14, so that the fabric 14 moves in the container while rotating forward with respect to the rotation direction of the kneading blade 8. To go. As a result, the inside of the container 9 is in contact with the dough 14 throughout and the food material is collected into the dough 14 without leaking, and the dough 14 is uniformly kneaded, generating a kneaded part and an unkneaded part in the dough. Can be prevented. Therefore, when a bread pizza is made using this dough, there is no partial unevenness in quality, and a high quality bread pizza can be obtained.
[0013]
Further, the blade of the shaft portion 10 is provided at a height that is raised in the order of the rotation direction in the order of the upper blade 11 at the uppermost stage, the middle blade 12 at the middle stage, and the lower blade 13 at the lowermost stage, and the rotation radius of the blade. The upper blade 11, the middle blade 12, and the lower blade 13 are increased in this order. As a result, the blade contacts the fabric in the order of the upper blade 11, the middle blade 12, and the lower blade 13, which have a smaller radius of rotation with respect to the fabric 14. Therefore, the dough 14 receives a radial force with respect to the rotation of the kneading blade 8 and rhythmically rotates while being pressed against the inner wall of the container 9. As a result, the dough 14 can be effectively kneaded to obtain sufficient gluten production, and a high-quality bread / pizza dough can be manufactured.
[0014]
Further, the upper blade 11 is provided with an elevation angle portion 16 by a chamfered shape, and the lower blade 13 is similarly provided with a depression angle portion 17 by a chamfered shape. As a result, the ingredients at the bottom of the container can be blown up by the rotational force of the depression 17 of the lower blade 13 during powder combination, and the ingredients at the top of the container are blown up by the rotational force of the elevation 16 of the upper blade 11. It can be pushed down (see FIG. 4).
[0015]
As a result, the highly sticky powder and water semi-mixed food that stays and adheres to the bottom of the container at the time of powder mixing is quickly and effectively collected by the lower blades to form dough dumpling, and from the powder mixing process to the quick kneading process The food material blown up by the depression angle portion 17 of the lower blade 13 is pushed down by the rotational force of the elevation angle portion 16 of the upper blade 11, so that the material can be prevented from scattering and adhering to the inner surface of the lid 15. The same effect can be obtained by tilting the entire upper blade and lower blade to give an elevation angle and a depression angle.
[0016]
Further, the shaft portion 10 extends to the vicinity of the lid 15, and a convex portion is provided at the center portion of the lid 15 toward the shaft portion 10. In addition, the uppermost upper blade 11 is provided near the uppermost portion of the shaft portion. The radial force that the fabric 14 receives from the blades is proportional to the radius of rotation of the blades according to the laws of physics. Therefore, when there is a large space between the shaft portion 10 and the inner surface of the lid 15 and the fabric 14 has entered between them, the fabric near the upper portion of the shaft portion 10 that is the center of rotation sticks to the inner surface of the lid center and jumps outside. It stays without. In addition, the dough is entangled with the kneading blade 8 entangled with the rotating shaft, causing large vibration and noise due to rotational imbalance, and causing severe damage to the bearing 6 due to the severe fluctuation of the load, leading to equipment failure. However, in this embodiment, the shaft portion 10 extends to the vicinity of the lid 15, and a convex portion is provided in the center portion of the lid 15 toward the shaft portion 10. Since the space is reduced, it is possible to reduce the chance and amount of the dough 14 entering during that time. Moreover, since the uppermost upper blade 11 is provided in the vicinity of the uppermost portion of the shaft portion, it is possible to fly the dough and prevent sticking to the inner surface of the lid center.
[0017]
【The invention's effect】
According to the present invention, at the time of dough kneading, any one of the upper blade, the middle blade and the lower blade can always receive a load force from the dough, and the load force from the dough received during one rotation of the kneading blade can be reduced. Variation can be reduced. As a result, vibration and noise of the equipment during operation can be suppressed, and it is possible to prevent the user from feeling uncomfortable, and the equipment moves violently on the installation surface, for example, when placed on a table. It is possible to prevent the device from falling from the table and being damaged.
