[0037] Please refer to Figure 1-Figure 6 The embodiment of the present application provides a dough kneading assembly, including a dough kneading barrel 1 and a dough kneading knife 2 arranged in the dough kneading barrel 1, the dough kneading knife 2 includes a curved kneading plate 21 and a stirring shaft 22 arranged on a side of the length direction of the kneading plate 21, the two ends of the stirring shaft 22 are rotatably abutted against the inner wall of the dough kneading barrel 1 in the horizontal direction, and a dough kneading gap 3 is formed between the dough kneading knife 2 and the dough kneading barrel 1.
[0038] The implementation principle of the embodiment of the present application is as follows: on the one hand, by setting the kneading knife with a curved surface in the length direction of the stirring shaft, the force area of the dough and water is greatly increased, and the dough and water are made to flow in the direction where they are most likely to form a dough; on the other hand, by setting the stirring shaft on one side of the kneading knife and arranging it horizontally in the dough kneading barrel, the spatial change rate of the dough is greatly increased. The huge spatial change allows the dough to be fully kneaded and pressed, thereby quickly kneading the dough into a dough. The embodiment of the present application can shorten the dough kneading time of 15 minutes required by the prior art to about 5 minutes, and can achieve the effect of forming a dough with a dough-water ratio of less than 10:4 (Chinese dough).
[0039] In some possible embodiments, the inner wall of the dough kneading barrel 1 is provided with ribs 11, and the height of the ribs 11 is less than the width of the dough kneading gap 3. The ribs 11 can exert further impact force on the dough and water during the rotation of the dough kneading knife 2, which is conducive to quickly kneading the dough into a ball; and because the curved dough kneading knife 2 intersects with the lowest point of the ribs 11 during the rotation process, the load of the motor is minimized without affecting the dough kneading effect, and the power required for dough kneading is reduced.
[0040] In some possible implementations, the dough kneading gap 3 gradually becomes smaller from top to bottom. The space indentation from high to low allows the dough to be kneaded more fully at the bottom, which is more conducive to quickly kneading the dough into a ball.
[0041] In some possible implementations, the dough kneading gap 3 includes a horizontal gap 31 formed between the kneading panel 21 and the inner side wall in the length direction and a height gap 32 formed between the kneading panel 21 and the dough kneading barrel in the width direction. In view of the limited horizontal space, the spatial change of the embodiment of the present application is mainly realized in the height direction. Therefore, in some possible implementations, the height gap 32 gradually decreases from top to bottom; the width of the horizontal gap 31 is consistent from top to bottom; and the horizontal gap 31 is smaller than the height gap 32.
[0042] In some possible implementations, the stirring shaft 22 is arranged lower than the center of gravity of the dough kneading barrel 1. The lowering of the center of gravity of the stirring shaft 21 further reduces the bottom space, and this space change allows the dough to be kneaded more fully at the bottom, which is more conducive to rapid dough kneading.
[0043] Exemplarily, the minimum value of the height gap 31 can be set to 10-25 mm; the height of the tendons 11 can be set to 2-10 mm.
[0044] In some possible embodiments, the bottom surface of the dough kneading barrel 1 is an arc-shaped surface, and the ribs 11 are arranged on the arc-shaped surface to maximize the impact force and spatial compression effect on the dough; the front and rear side walls of the dough kneading barrel are an inverted trapezoidal structure with a larger top and a smaller bottom; the left and right side walls of the dough kneading barrel are a planar structure inclined inward and downward.
[0045] In some possible implementations, the bucket cover of the dough kneading bucket is provided with two symmetrical arc-shaped depressions, and water can be poured into the bucket from the arc-shaped depressions during use. Due to the symmetrical arrangement, the operation is easier and the user experience is improved.
[0046] In some possible implementations, the tendons 11 are disposed away from the vertical center line of the arc-shaped surface, so that when the dough hits the tendons 11, a gravity component is added, thereby achieving a better collision effect.
[0047] In some possible embodiments, the projection of the dough kneading knife 2 in the length direction is one or more arcs, and the projection in the width direction is a straight line, that is, the kneading panel 21 is configured as a plate-like structure with one or more arc surfaces, which can increase the contact area and guide.
[0048] In some possible implementations, a transmission shaft 103 is provided in the dough kneading barrel 1, and the stirring shaft 22 is configured as a hollow cylindrical structure that is synchronously rotatably sleeved on the outside of the transmission shaft 103. This structure is easy to install and disassemble, and can achieve the best synchronization effect.
[0049] In some possible implementations, the inner side surface of the stirring shaft 22 is set as an inner hexagonal surface 24, and the outer side surface of the transmission shaft 102 is set as an outer hexagonal surface matching the inner hexagonal surface. The hexagonal surface plays a synchronization role and is simple and convenient to process.
[0050] An embodiment of the present application also provides a dough mixer, which includes a drive motor 101 arranged in a main base 100 and a dough mixer assembly detachably connected to the drive motor 101, wherein the dough mixer assembly is configured as a dough mixer as described in the aforementioned embodiment and at least one of any embodiments thereof. Accordingly, its technical effects are also fully extended to this embodiment and will not be repeated.
