Abstract
Description
Technical Field
[0001] This utility model relates to the field of vaccine production technology, and in particular to a mixing device for a mixing tank used in vaccine production. Background Technology
[0002] Vaccines typically consist of multiple components, such as antigens, adjuvants, preservatives, and buffer solutions. Mixing and stirring ensures these components are fully and evenly distributed in the solution, guaranteeing accurate and consistent component ratios in each batch of vaccine. This ensures the stability and effectiveness of the vaccine, allowing each dose to produce the same immune response.
[0003] Existing mixing tanks for vaccine production use a drive motor directly connected to the mixing shaft for stirring. However, direct stirring results in greater resistance to the rotation of the mixing shaft, requiring more power for liquid stirring, which is not conducive to reducing production costs for enterprises. Furthermore, the greater resistance and frictional heat may affect the efficacy of the vaccine, causing certain adverse effects on users. To address the shortcomings of existing technologies, we propose a mixing device for mixing tanks used in vaccine production. Utility Model Content
