Description

technical field [0001] The invention belongs to the technical field of pharmaceutical production equipment, in particular, the invention relates to a medicine powder mixing device. Background technique [0002] In the chemical industry and biopharmaceutical fields, the mixing of solid powder or granules often requires relatively professional large-scale machinery. These large-scale machinery generally have complex structures and high procurement costs. Once a failure occurs, it is difficult to maintain and seriously affects industrial production. efficiency. [0003] In many mixing devices, the raw materials at the bottom cannot be stirred, sink to the bottom and cannot be mixed, and the mixing layers at different levels cannot be exchanged with each other, and faults appear, resulting in poor mixing effect. Contents of the invention [0004] The invention provides a medicine powder mixing device, which can mix raw material medicine powder in the device and mix them evenl...
