摘要:
A doughnut dough shaping machine, has a plurality of shaping bodies, which constitute a shaping part, arranged at predetermined gaps and coupled between two disc-type shaping support parts; has a cylinder rod-shaped operating part, which comprises a coupling part and a handle part, provided at through-parts perforated at the center of each shaping support part by means of bearing parts, so as to roll the shaping support parts and the shaping part on the upper surface of the doughnut dough, thereby making a uniform doughnut; and cuts only both end sections of the doughnut dough by non-cut shaping parts at the centers of the shaping bodies and cut-shaping parts at both ends thereof, such that the cut doughnut dough is overlapped in a cylinder shape, thereby producing a flower-shaped doughnut.
