[0003] One of the raw materials used in the production of lactic acid powder is glucose. A powder metering machine is required for the batching of glucose powder. When the existing powder metering machine is used, the material is fed through a screw conveyor. After the material is fed to the lower hopper, the material falls into the lower hopper. The motor drives the rotating rod to rotate, and the rotating rod drives the spiral rod to rotate, thereby realizing the metering and preparation of glucose powder. In the whole process, there are the following problems:

[0004] 1. When the lower hopper receives materials, the input of materials is relatively concentrated, which is not conducive to the uniform distribution of materials;

[0005] 2. Impurities that may be contained in the powder are easily discharged from the bottom of the hopper along with the powder, resulting in impure substances.

[0006] Therefore, it is necessary to provide a new metering system for lactic acid powder production to solve the above-mentioned technical problems. Utility Model Content
