For example, granules are products in granules and capsules, and the purpose of granulation is not only to improve the flowability, dispersibility and adhesiveness of materials, facilitate accurate metering, protect production environment and the like, but also to ensure uniform shape and size, beautiful appearance and the like of the granules. In the production of tablets, granules are intermediates, and not only is the flowability improved to reduce the weight difference of tablets, but also the compression moldability of granules is ensured. There are various granulation methods, and even with the same formulation, not only are the shapes, sizes, and strengths of the obtained granules different, but also the disintegratability and solubility are different, resulting in different drug effects. Therefore, a suitable granulation method should be selected according to the characteristics of the desired granules.

In the existing preparation equipment, a mature production line is provided, and generally, after medicines and auxiliary materials are mixed, the medicines and the auxiliary materials are pressed into thin slices with required hardness through gaps among 2 rolling cylinders with the same rotating speed, and then the thin slices are crushed into particles with certain size through a granulator. The equipment is not beneficial to granulation of wet medicines in actual application, and because the wet medicines generally have viscosity and can adhere to the rolling cylinder when passing through the rolling cylinder to block gaps, the existing equipment usually needs to be added with medicine drying equipment to avoid the phenomenon that the medicine adheres to the rolling cylinder, so that the whole production line is too long and the required equipment is too much; and particularly for medicines with moisture, the drying can reduce the efficacy of the medicines and is not beneficial to the granulation of the medicines. Based on this, the utility model designs an equipment that is favorable to moist medicine pelletization.
