People take food as a day, wherein food stirring plays an important role in our daily life. Early food blending relied on manual work. With the development of the technology, a food mixer is provided, which not only reduces the labor intensity of people in the food processing process, but also improves the quality of food. Flour mixing is the most common food mixing, and is particularly obvious in the process of making bread.

When making bread, in order to improve the working efficiency, the automatic equipment is gradually adopted to carry out various operations. In the prior art, the flour mixer is used for mixing the dough to achieve the effect of automatic dough mixing. However, in the existing dough fermenting and stirring machine, the stirring teeth can only realize the rotation stirring of flour, so that the stirring efficiency is low, the dough rolling time is long, and the time for the dough to reach the completion stage is long. Especially, the flour with strong gluten is stirred for a long time, so that the gluten can not meet the use requirement. The dough also loses good extensibility and elasticity, and cannot reach the expansion stage after being rolled up, so that the dough becomes crisp and wet, and the quality of the bread is greatly influenced. To this end, we propose a dough mixer.
