[0004] However, the existing flour grinding devices also have certain shortcomings. First, the existing flour fine grinding devices simply use two grinding rollers to rotate in opposite directions to grind the flour raw materials in the gap between the grinding rollers. Due to the influence of factors such as the feeding rate and the extrusion area, the fineness of the flour grinding is relatively weak.

[0005] Secondly, when the existing flour grinding device processes the material feeding, due to the adhesion characteristics of flour, the inner wall of the feeding barrel will be adhered to flour, which will easily cause the accumulation and waste of flour in the long run. Utility Model Content
