Description

Technical Field

[0001] This utility model relates to the field of liquid preparation tank technology, specifically to a liquid preparation tank for medicine. Background Technology

[0002] In many industries such as pharmaceuticals and chemicals, mixing tanks are key equipment for achieving material mixing and play a crucial role in ensuring product quality. In the pharmaceutical field, precise drug solution preparation directly affects the efficacy and safety of drugs; in the chemical industry, the effectiveness of solution preparation influences product performance and quality.

[0003] Currently, most existing drug preparation tanks use electric heating. However, this method has significant drawbacks, easily leading to uneven heating of the drug solution. From a heating principle perspective, electric heating typically relies on resistance wires or heating rods to transfer heat. The distribution of these wires or rods within the preparation tank is difficult to achieve perfectly uniformly, and after prolonged use, aging or deformation of the wires or rods can further exacerbate this uneven heating. This results in varying degrees of heating in different areas of the drug solution within the tank. Some solutions may be overheated, potentially causing decomposition or deterioration of their active ingredients, thus reducing efficacy or affecting product performance; while other solutions may be underheated, failing to fully dissolve or participate in the reaction, significantly reducing the effectiveness of the preparation and ultimately affecting the stability and consistency of product quality.

[0004] Therefore, there is an urgent need to develop a new type of drug solution preparation tank to overcome the problem that the current drug solution preparation tanks use electric heating, which easily leads to uneven heating of the drug solution and affects the preparation effect.
