A kind of manufacturing method and equipment of nifuratel nystatin suppository

Abstract

The invention relates to the technical field of pharmaceutical manufacturing, in particular to a method and equipment for manufacturing a nifuratel nystatin suppository; the primary product suppository prepared by a centrifugal spray granulator is transported into a cloth bag, and sent into a drying box through an air supply assembly. Blow air to dry the primary suppository. After drying, start the first electric push rod to make the cloth bag protrude, so that the dried suppository will fall into the collecting hopper under the action of gravity, and then be transported to the screening box Inside, through the first screening mechanism and the second screening mechanism in turn, the suppositories that do not meet the specifications are screened out, so as to obtain the finished suppository. Compared with the traditional method, each process is set independently, and the degree of manual intervention is higher. The structure is highly integrated, and the degree of manual intervention is low, thereby improving the efficiency of preparing suppositories.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical manufacturing, in particular to a method and equipment for manufacturing nifuratel nystatin suppositories. Background technique [0002] Nifuratel (Nifuratel) is a broad-spectrum antibacterial drug, which belongs to the class of furazolidone (this class of drugs also includes nitrofurazone, nitrofuran, and diphenhydramine). [0003] In the process of manufacturing nifuratel nystatin suppositories, it is necessary to dry and sieve the initial suppositories obtained by the centrifugal spray granulator to obtain finished suppositories. [0004] In the existing manufacturing process of nifuratel nystatin suppositories, most of the equipment for drying and screening the initial suppositories are independently set up, which requires a high degree of manual participation, resulting in low production efficiency. SUMMARY OF THE INVENTION [0005] The object of the present invention is to provide ...
