Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production, and particularly relates to a raw material mixing device for pharmaceutical production. Background Art

[0002] The active pharmaceutical ingredient (API), as the basic raw material for producing various preparations, is the core component constituting the efficacy of the preparations. These APIs can be prepared by chemical synthesis, plant extraction or biotechnology, and have various forms, including powders, crystals, extracts, etc., but are not suitable for direct administration to patients. The APIs must be further processed into pharmaceutical preparations before they can be applied to clinical treatment. And in the production process of APIs, the mixing link is particularly crucial.

[0003] In the production process of APIs, the mixing device is an indispensable equipment for uniformly mixing various raw material components. However, most of the common APIs mixing devices on the current market only rely on the motor to drive the stirring blades to rotate in the stirring barrel to achieve the mixing of raw materials. This method often results in insufficient mixing of APIs and relatively low mixing efficiency. In view of this, in-depth research on the above problems has led to the generation of this case.
