Technical Field

The embodiment of the invention relates to the technical field of food processing production machinery, in particular to a dough kneading machine and a control method thereof.

Background

The wheaten food is one of the main foods of Chinese people, and the traditional wheaten food comprises noodles, steamed bread, steamed stuffed buns, steamed rolls, oil cakes and the like; the traditional wheaten food is mostly made manually, people firstly mix flour and water and stir the mixture evenly, then repeatedly knead the mixture, namely dough kneading is often called, the flour is made into dough, sometimes leavening agents are needed to be added into the dough to ferment the dough, then the dough is made into different shapes, and then the dough is baked, steamed and fried to be made into different wheaten food for people to eat.

In order to meet the requirements of demand and processing speed, people generate processed wheaten food in a mechanized mode, and repeatedly knead and press dough by using a dough kneading machine to replace manual kneading, so that the kneading process is mechanized, and the working strength brought by kneading dough by workers is greatly reduced. Because of high kneading efficiency and uniform kneading, the dough kneading machine is widely applied to food processing enterprises. However, the existing wheaten food processing machines and wheaten foods are simply and uniformly stirred and then are prepared by pressing, repeated kneading cannot be realized, and the wheaten foods prepared by the wheaten food processing machines have poor mouthfeel. The dough sheet that current malaxator generally needs the manual work to pressing into is folded, sends into and kneads the pressure operation once more in the conveyer belt, needs personnel to operate always, kneads dough efficiency comparatively lowly.
