Description

Technical Field

[0001] The present invention relates to the technical field of flour stirring, in particular to flour stirring equipment. Background Art

[0002] In the preparation of cake batter and dough such as bread and noodles, water is often added to flour and stirred to form batter or dough. Current stirring components have dead corners, making it difficult to evenly mix all the flour in a short period of time. Part of the dough is often over-stirred, resulting in gluten fatigue and the gluten network structure changing from a dense to a loose structure. In addition, some flour is not stirred for enough time during the agglomeration process, and water absorption is insufficient, so that the gluten protein fails to stretch out to form a network structure. These factors will affect the formation of an effective network structure of gluten protein in flour, leading to the existence of this phenomenon, a large part of which comes from the stirring component. In response to these problems, the present invention designs a new stirring component to eliminate the problem of uneven stirring during the formation of batter or dough. Summary of the Invention

The second stirring rod 13 is rotatably mounted on the third connecting plate 10. The second motor 14 is mounted on the third connecting plate 10 and drives the second stirring rod 13 to rotate.

[0028] In this embodiment, the driving mechanism drives the mixing drum 2 to rotate, and the first stirring member and the second stirring member stir and mix the flour and water in the mixing drum 2. The first stirring member can rotate around the support shaft 3 as the mixing drum 2 rotates. When the first stirring member gradually approaches the second stirring member, the driving mechanism drives the mixing drum 2 to reverse. When the first stirring member gradually approaches the second stirring member again, the driving mechanism drives the mixing drum 2 to rotate forward again, and the flour and water are repeatedly mixed in this way. At the same time, the first scraper 6 can rotate as the mixing drum 2 rotates. The rotation of the first scraper 6 can scrape off the flour attached to the support shaft 3, and the second scraper 7 can scrape off the flour attached to the inner wall of the rotating mixing drum 2 to prevent some flour from not being stirred.

[0029] Specifically, if Figure 6 As shown, the inner wall of the mixing drum 2 is provided with a vertically arranged first slot, and the first mounting plate 4 is inserted into the first slot.
