[0033] In related technologies, vacuum dough mixers simulate manual dough kneading under vacuum and negative pressure created by a vacuum pump. This can increase the moisture content of dough by 10% to 20% compared to normal kneading, rapidly forming a gluten network and balancing the protein structure. The resulting dough is glossy, uniformly firm, and elastic, with enhanced gluten strength. This significantly improves dough quality, resulting in smooth, translucent, and elastic noodles. Traditional vacuum dough mixers use a single shaft to stir the dough, resulting in low mixing efficiency and impacting production efficiency.

[0034] Reference Figures 1 to 4According to an embodiment of the present invention, a vacuum dough mixer includes a machine base 100, a dough box 200, a box cover 300 and a stirring assembly 400. The machine base 100 is provided with a driving assembly, the dough box 200 is provided on the machine base 100, the dough box 200 is provided with a dough mixing chamber 210, the box cover 300 can be movably provided on the dough box 200 to open or close the dough mixing chamber 210, the box cover 300 is provided with a vacuum joint 310, the vacuum joint 310 is used to connect with the vacuum assembly, the stirring assembly 400 includes a pivot seat 410 and a plurality of stirring shafts, the pivot seat 410 is rotatably provided in the dough mixing chamber 210, the driving assembly The plurality of stirring shafts are rotatably arranged on the pivot seat 410 through the first transmission structure, and the plurality of stirring shafts are arranged at intervals along the circumference of the pivot seat 410. Each stirring shaft is provided with a stirring member 430 for stirring flour and water. The stirring shaft is connected to the pivot seat 410 through the second transmission structure. In this way, the stirring shaft can rotate around the axis of the pivot seat 410 and the stirring member 430 can rotate around the axis of the stirring shaft. The stirring member 430 can perform a compound motion, can efficiently stir flour and water, improve the stirring efficiency of the vacuum noodle mixer, and thus improve the production efficiency of the vacuum noodle mixer.

[0035] For example, when the vacuum dough mixer is kneading dough, the vacuum assembly extracts air from the dough mixing chamber 210 through the vacuum joint 310 to put the dough mixing chamber 210 in a negative pressure state, and the driving assembly drives the pivot seat 410 to rotate through the first transmission structure. Under the rotation of the pivot seat 410, the pivot seat 410 drives the stirring shaft to rotate through the second transmission structure, so that the stirring shaft can rotate around the axis of the pivot seat 410 and the stirring member 430 can rotate around the axis of the stirring shaft. The stirring member 430 can perform a compound motion, can efficiently stir flour and water, improve the stirring efficiency of the vacuum dough mixer, and thus improve the production efficiency of the vacuum dough mixer.

[0036] Moreover, by providing a single driving component that can drive the stirring element 430 to perform a compound motion, the material cost of the driving component can be saved, thereby reducing the production cost of the vacuum dough mixer.
