Problems solved by technology

[0004] In the above-mentioned Patent Document 1, the agglomerated medicinal powder is crushed by the rotation of the crushing knife and the stirring rod, so that the medicinal powder is crushed into granules. In this invention, the blending blade and the anti-clogging rod are combined so that the medicinal powder will not block the feed pipe, but this When the invented stirring rod and pulverizing knife crush the medicinal powder, some medicinal powder will remain above the stirring rod and pulverizing knife, and agglomerates will appear as time accumulates, affecting the pulverization of the medicinal powder by the stirring rod and pulverizing knife, making the medicinal powder The pulverization is not thorough, and the practicability of the invention is not high. At the same time, when the invention stirs the powder with the stirring blade, the powder will move horizontally in the guide tube, thereby generating extrusion force and causing the powder to agglomerate
