[0002] In pharmaceutical manufacturing, it is sometimes necessary to mix and stir ingredients to achieve mixing, dissolution, or reaction. However, most existing pharmaceutical mixing tanks use fixed-structure stirring mechanisms to mix materials, which cannot be adaptively adjusted according to the different viscosities of the materials. This makes it difficult to guarantee the mixing effect and creates dead zones, resulting in low mixing efficiency. Furthermore, existing pharmaceutical mixing tanks require disassembly and cleaning, which can damage the tank's sealing structure and cause material contamination, making them impractical. Therefore, we propose a pharmaceutical mixing tank to solve the above problems. Utility Model Content
