Quick-frozen jiaozi is a kind of food that can be eaten at any time after the wrapped jiaozi is quickly frozen. Jiaozi is a traditional special food loved by the Han people in China, and it is a must-eat food during the Spring Festival every year. According to legend, jiaozi was first invented by Zhang Zhongjing, a doctor in Nanyang, Henan Province during the Eastern Han Dynasty in China. In many provinces and cities in China, there is also the habit of eating jiaozi on the solstice in winter.

Jiaozi, after the expansion of the modem packaging system, should be carefully handled and manually reshaped to maintain 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.
