Dough fermentation device for fermentation engineering

The invention discloses a dough fermentation device for fermentation engineering, and relates to the technical field of fermentation engineering. The dough fermentation device for the fermentation engineering comprises a dough fermentation mechanism used for kneading dough, a dough extrusion mechanism used for extruding the dough and a dough stirring mechanism used for stirring the dough, a circular shell is arranged in the dough fermentation mechanism, and the dough fermentation mechanism is fixedly connected with the dough extrusion mechanism through the top of the arranged circular shell. According to the dough fermentation device for the fermentation project, air is blown into an extrusion roller through a blower, so that air flow is blown out from a conical opening of the extrusion roller, then flour in the circular shell continuously floats up and then falls down, gathered flour is separated and stirred, in the process that the extrusion roller extrudes dough, the flour which is not soaked can be clampe
