Food fermentation process

The invention relates to the field of fermentation, and particular relates to a food fermentation process. The food fermentation process facilitates uniform fermentation, so as to improve food quality. The process comprises the following steps: Step 1, mixing active dry yeast powder with clear water (20 DEG C) to obtain yeast water; Step 2, mixing the yeast water with flour to obtain dough; Step 3, putting the dough into a dough kneading device to be kneaded; and Step 4, moving the kneaded dough into a heat preservation box, carrying out fermentation with the fermentation temperature controlled at 35 DEG C, and finishing fermentation until the size of the fermented dough is twice that of the kneaded dough. The dough kneading device comprises a bottom frame, a dough kneading block, a mounting rod and an arc-shaped plate, a pin shaft is arranged at the lower end of the arc-shaped plate, the pin shaft is connected to the bottom frame, the dough kneading block is fixed to one end of the mounting rod, and the moun
