Dumpling wrapper forming device and forming method thereof

Technical Field

The invention relates to the field of food processing, in particular to a dumpling wrapper forming device and a forming method thereof.

Background

Dumplings are derived from ancient horns. The original name of dumpling "Jiaoeng ear" is invented firstly by south Yang people in China in the holy Zhang Zhongjing, and has a history of more than one thousand and eight hundred years. Is a traditional special food which is deeply loved by Chinese people, is also called as dumpling, is staple food and local snack of Chinese people, and is also a festival food. A ballad called "big cold and small cold", is used for a long time. The dumpling is made by boiling the stuffing in water.

The traditional dumpling wrappers are mostly formed by manually rolling, the manually rolled dumpling wrappers are thick in the middle and thin in the edge, and the stuffing is not easy to expose after being boiled in water, so that the traditional dumpling wrappers are the first choice of traditional families. However, for the rapid development of life rhythm today, directly purchasing own dumplings made of dumpling wrappers or directly purchasing quick-frozen dumplings becomes the first choice of many young people. However, because the manual rolling has low efficiency and is easy to fatigue, and the manual rolling cannot adapt to large-scale production, the research and development of the automatic forming device of the dumpling wrappers becomes a key problem of many food enterprises.

At present, although the efficiency of the dumpling wrapper forming device which is popular in the market is improved compared with the manual work, the dumpling wrapper forming device still has the following problems: for example, in a common dumpling wrapper noodle press, the loose dough is pressed into a noodle belt firstly, and then the dumpling wrapper is obtained by adopting a circular mold to press and intercept, the processing method can generate more leftover materials, the waste materials are not easy to be reprocessed, the waste of raw materials is avoided, the reprocessing cost is high, and the later stage edible taste is relatively influenced even if the dumpling wrapper after being reprocessed and utilized, so that the product quality is seriously influenced.
