Description

Background

The wheaten food is common food in northern China, the production of the wheaten food needs to be completed through a plurality of steps of dough kneading, kneading and pressing, dough blank forming and the like, and mechanical equipment is usually used for replacing manual dough kneading and forming and the like for food processing departments in large-scale production.

At present, dough kneading mechanisms of common wheaten food processing equipment on the market can be roughly divided into a horizontal stirrer and a vertical stirrer, and most products adopt a horizontal structure, namely, a stirring shaft is horizontally arranged in a square stirring box. The dough kneading mechanism with the structure has the problems of poor dough kneading effect, poor mouthfeel of cooked wheaten food, low efficiency and the like in actual use due to the following reasons:

because the stirrer is horizontally arranged, when the stirrer works, the stirring teeth or blades and other components do circular motion around the stirring axis, the plane formed by the motion track is vertical to the box bottom plate, the stirring teeth and other components dial the dough (or food materials) to turn over up and down around the axis, the stirring action is simple and different from the traditional manual dough kneading method, because the stirring mode lacks kneading action, the stirring time needs to be properly increased, and the kneading effect of the dough and the taste of finished wheaten food products are far inferior to the traditional processing method; in the dough kneading process, larger dough is easily stuck and hung on parts such as stirring teeth, shafts and the like, small blanks or scraps are thrown and hit by the stirring teeth and are adhered and accumulated at corners of a box body, and once the conditions occur, the machine is usually stopped, so that the taste of food materials is influenced, the processing efficiency is indirectly reduced, and the problem is particularly obvious for softer dough such as fried bread sticks, vermicelli and the like. Another disadvantage of the horizontal type structure is that it is limited by the structure of the horizontal agitator, and the cleaning work inside the tank needs to be performed by bypassing the agitator part, which is time-consuming and labor-consuming.

In addition, a few dough kneading devices with vertical stirrers are additionally arranged, the stirring direction of food materials is only changed, and the problems of low operation efficiency of products with a horizontal structure, lack of kneading pressure of dough blanks, poor mouthfeel of finished wheaten food products and the like are still not solved.
