Jiaozi was frozen hard at first, and then it was soft and sticky. Then jiaozi will swell up and float on it like a ball. In the end, jiaozi's stomach will be flat (but jiaozi is not rotten). Intuitively, you will find that jiaozi's leather bag has a concave-convex feeling on the dumpling stuffing. At that time, jiaozi ripe.
Jiaozi packaging system:
Jiaozi molding machine is often used to make jiaozi in large-scale industrial production. Dumpling skin is an extremely important technical link in the production of jiaozi, which is directly related to the quality problems such as the shape, size, weight, thickness, skin filling ratio and so on.
Jiaozi made by machine should be handled carefully and molded by hand to keep the good shape of jiaozi. In plastic surgery, some unqualified jiaozi, such as flat belly, missing horn, cracking and abnormity, should be eliminated.
When shaping, if the force is too strong or the holding method is unreasonable, the arrangement is too tight, and they squeeze each other, the shaped jiaozi will be flat, the deformation is not full, and even the juice will flow out and stick together, and the dumpling skin will crack. Plastic jiaozi should be sent to the quick freezing room for freezing in time.
