Description
Mixing equipment for producing medicine powder Technical Field The utility model relates to the technical field of powder mixing, in particular to powder production mixing equipment. Background The powder production mixing equipment is core equipment in the pharmaceutical industry and is mainly used for uniformly mixing various drug powders (including active drug ingredients and auxiliary materials such as filling agents, disintegrating agents, lubricants and the like) so as to ensure the consistency and stability of the drug ingredients. In the mixing process, a double-screw stirring structure is adopted, and the rotation stirring and up-down turning of the powder can be realized through the compound motion of revolution and autorotation, however, as the spiral blade has a contact blind area in the middle shaft area of the stirring barrel, the stirring force applied to the raw materials in the area is insufficient, thereby affecting the mixing uniformity of the powder and prolonging the time required for mixing. Therefore, aiming at the situation that the prior powder mixing equipment has insufficient stirring force of raw materials in the area because of the contact dead area of the spiral blade in the middle shaft area of the stirring barrel, the mixing uniformity is affected and the mixing time is prolonged, the improved powder production mixing equipment can be designed, and the mixing efficiency is improved. Disclosure of utility model In order to overcome the problem that in the process of mixing the powder, the stirring device adopting the double-screw stirring structure can realize the rotation stirring and the up-down turning of the powder, but because the intermediate shaft area of the double-screw stirring structure has a contact dead zone, the stirring force of the raw materials in the area is insufficient, thereby affecting the mixing uniformity and prolonging the mixing time.
