Description

Technical Field

[0001] The utility model belongs to the technical field of bread making, in particular to a raw material stirring device for making highland barley bread. Background Art

[0002] During the production process of highland barley bread, it needs to be fully stirred to ensure that the raw materials are fully mixed. Through continuous kneading, the protein in the flour will gradually gather together to form gluten. Gluten is a dense, network-like, elastic structure composed of the protein in the flour.

[0003] Generally speaking, the longer the mixing time, the more gluten will be formed in the dough, and the gluten can wrap the air produced by yeast fermentation, forming countless tiny pores. After baking, the protein gradually solidifies and forms a solid organization, thus achieving the structural function of supporting the bread. If the air is not mixed in enough, the number of bubbles will decrease, and the bread will become rougher, affecting the taste and appearance of the bread. Therefore, the quality of the finished bread depends largely on the quality of mixing, and the mixing quality is affected by the amount of air mixed in during mixing.

[0004] Most existing mixing equipment rotates and stirs in the same direction, and cannot knead in multiple directions like manual kneading. It is impossible to incorporate air into the dough from multiple directions, resulting in insufficient air mixing. Prolonging the mixing time may lead to excessive mixing, causing the gluten to lose elasticity and affecting the taste. Utility Model Content

The extrusion column rotates with the barrel, and the extrusion column and the main shaft rotate in opposite directions.
