Abstract:
A dough preparation machine includes a power unit, which drives, through rotational speed mechanism, a helical screw shaft that extends into a dough chamber so that the dough is compressed and pushed through rotation of the helical screw shaft to be discharged out of a jet nozzle mounted to the dough chamber. The dough chamber is provided, at a location above the helical screw shaft, with an auxiliary dough driver, which includes two movable blades that are opposite to each other and are selectively extendable outward and retractable inward. When one of the movable blades passes through a circular sidewall of dough chamber, it is pressed by the sidewall to get retracted inwardly and at the same time causing another one of the movable blades to extend outward to knead and poke dough. This process is cyclically repeated to efficiently knead the dough and prevent attachment of the dough.
