PROBLEM TO BE SOLVED: To provide such raw jiaozi that: although hydro-jiaozis wrapping is thick and rich in moisture, in the case of this raw jiaozis wrapping, the joint causes neither hardening nor getting out of shape even if boiled, and having a stable surface, thus arrangeable properly in a container box and to provide an automatic production machine therefor.SOLUTION: The raw jiaozi has an elliptic stable surface and a semicircular joint on the upper part in the major direction of the elliptic surface. In the jiaozi, while one side with the joint as boundary is plainly recessed surface, the other side is formed of a synthesized uneven surface, and there are ribs partitioning the synthesized uneven surface. The automatic production machine for the raw jiaozi is also provided, including: a wrapping-forming apparatus a wrapping puncher an ingredient feeder a wrapping squeezer and a raw jiaozi joint-forming apparatus.COPYRIGHT: (C)2011,JPO&INPIT【課題】水餃子用の皮は厚く、水分を多く含んでいるが、茹でても合わせ目はこわばらずしかもほころびないこと。そしてしっかりしたすわり面があり、容箱にきちんと整列した生餃子と、その自動製造装置を得ることにある。【解決手段】長円形のすわり面があり、その長径方向の上部には半円状の合わせ目があり、合わせ目を境とする片面はのっぺりした凸面であるのに対し、他の片面は合成された凹凸面で形成され、その面を区画するリブを有する生餃子とし、自動製造装置に皮成形装置と皮打ち抜き装置と具供給装置と皮絞り装置と生餃子の合わせ目形成装置とを備えたものとした。【選択図】図2
