Description

Technical Field

[0001] The utility model relates to the technical field of flour production, in particular to a high-efficiency grinding device for flour production. Background Art

[0002] Flour is a common food in people's daily life. When producing flour, a grinding device is needed to grind wheat into flour. A movable mounting structure is provided to facilitate the disassembly and assembly of the grinding structure and the cleaning of the grinding device.

[0003] A Chinese utility model patent with authorization announcement number CN220277109U discloses a flour grinding device, comprising a housing, a support, and a base, wherein the support is mounted on the outer wall of the housing, and the base is fixedly connected to the bottom end of the support. A grinding assembly is mounted inside the housing, and a fixed assembly is mounted on the outer wall of the housing. The grinding assembly is composed of a rotating unit and a closing unit, wherein the rotating unit is located above the base, and the closing unit is located on the outer wall of the housing. The flour grinding device is provided with a clamping rod and a grinding roller. Since the clamping rod is slidably connected to the grinding roller and a clamping strip is present on the surface of the clamping rod, the grinding roller can be limited. When the clamping rod rotates, the clamping strip can drive the grinding roller to rotate, thereby grinding the wheat. At the same time, the presence of the clamping strip does not affect the replacement of the grinding roller, making it convenient for operators to replace grinding rollers of different specifications according to different needs.

[0004] However, the existing flour production grinding device is not convenient for pre-processing wheat, has poor grinding efficiency, cannot efficiently screen the flour after grinding, and is inconvenient to remove unqualified flour. Therefore, we propose a high-efficiency flour production grinding device to solve the above problems. Utility Model Content
