Abstract

The invention provides a batch complete filtration process of API medicinal liquid in the pre-crystallization process in pharmaceutical production, including fine filtration with a rotary ceramic membrane filter, cluster filter filtration, cluster filter filtrate treatment, batch complete filtration, solid Impurity collection and CPI cleaning steps. The rotary ceramic membrane filtration concentration process is used as the precision filtration process, and the cluster membrane filtration technology is used as the solid-liquid separation treatment of the concentrated liquid in the rotary ceramic membrane filter, and the cluster filter filtrate is returned to the rotary ceramic membrane filter for circulation and filtration. Concentrate continuously, and finally use gas backflushing in the cluster filter to recover the impurities in the thick slurry in the form of solids to achieve complete batch processing. The whole process organically combines two kinds of filters, which makes the process simple, efficient and stable, easy to backwash and regenerate, and convenient to operate and maintain.

Description

technical field [0001] The invention relates to the technical field of filtration in the pre-transformation process of pharmaceutical production, in particular to a filtration process and method for API liquid (raw material medicine) with high-efficiency solid-liquid separation, in-situ cleaning, and complete batch treatment. Background technique [0002] API liquid medicine (raw material medicine) refers to the active substance used in the production of preparations, which is the main component processed into preparations, and is generally obtained by chemical synthesis, DNA recombination, fermentation, enzyme reaction or extraction from natural substances. The production of raw materials includes: chemical synthesis, most of the raw materials are synthesized, such as sulfadiazine; extraction, such as heparin extracted from pig intestines, chondroitin extracted from cartilage; fermentation, most antibiotics are derived from fermentation Processes, such as penicillin, strept...
