Description

Technical Field

[0001] The utility model relates to the technical field of granular medicine grinding and granulating, in particular to impact-type grinding and granulating equipment for granular medicine production. Background Art

[0002] Granular medicine refers to a dry granular preparation with a certain particle size made by mixing raw materials and suitable excipients. Chinese medicine granules are a type of medicine developed on the basis of decoctions. Chinese medicine granules can be swallowed directly or taken with water. They not only maintain the advantages of decoctions such as fast absorption and rapid effect, but also overcome the shortcomings of temporary decoction before taking decoctions, time-consuming and energy-consuming, and easy to mold and spoil after long-term storage. In the prior art, a swing granulator is generally required to make granular medicines. Its working principle is to use a swinging hollow drum to continuously hit the wet mass medicine to disperse the medicine and fall through the filter to form a granular medicine with a suitable particle size. However, in the actual production process, the granular medicine below the outlet of the traditional swing granulator is constantly stacked. Because the medicine has a certain humidity at this time, under the gravity pressure of the continuously stacked medicine, the medicine particles at the bottom are easy to re-bond and agglomerate, affecting the actual production effect of the granular medicine. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case. Utility Model Content

After the swing-type granulator granulates, the granular medicine first falls into the collecting hopper 1, and moves from top to bottom in the collecting hopper 1 under the centrifugal driving action of the first dispersion disk 6 and the second dispersion disk 7. During the movement, the hot air drying component is used to inject hot air into the collecting hopper 1, so that the drug particles are further dried, and the mutual adhesion between the particles is effectively avoided.
