The total number of such factories in China in 1982 was 1833, of which chemical raw material medicine factory 83, preparation factory 407, raw material and preparation

There are six main types of pharmaceutical factories:

Antibiotic factory

This pharmaceutical factory attaches great importance to the selection and breeding of bacteria. It uses fermentation technology to produce the antibiotics needed, and then uses an efficient and economical separation and purification process to obtain the finished product. In addition to providing commercial raw materials, it also has its own packaging for antibiotic powder injection and water Injections, tablets, capsules, etc. Starch and glucose workshops are also generally provided to provide cheap, high-quality raw materials for culture media. Some large factories have workshops for the required solvents and ion exchange resins. The fermentation tank capacity (m3) of the antibiotic factory is generally 100-130, and the largest is 300, which is controlled and controlled by the electronic computer. China is generally 50 to 60, the largest 100. Compressed air sterilization uses a new process, and fermentation medium tends to use continuous, efficient, and energy-saving equipment for sterilization.

Chemical synthesis pharmaceutical factory

Glass-lined reaction tanks are generally used in production, with large capacity (m3) 3 ~ 5, medium size 1 ~ 2, small size 0.1 ~ 0.5, and commonly used supporting equipment are: atmospheric or high vacuum distillation equipment, centrifuges, filter presses machine. In addition, there are high-pressure reactors, fixed-bed or fluidized-bed, gas-phase reaction devices, liquid-phase catalytic reaction devices, and ion-exchange columns.

Preparation factory

According to the principles of biopharmaceuticals and physical pharmacology, appropriate formulation auxiliary materials are added to chemical raw materials to process into various dosage forms. Some also produce phytochemicals or chemical synthetic drugs, which are produced and used by themselves.

Biochemical pharmaceutical factory

The vast majority of China's biochemical pharmaceutical factories are attached to meat joint processing plants. As a workshop that comprehensively uses livestock organs to produce medicines, it uses its fresh organ resources economically and reasonably to extract specific active ingredients and make them suitable. Pharmaceutical preparation. In addition to general injections, sugar-coated tablets, capsules, syrups and other dosage forms, freeze-drying equipment is often used to make freeze-dried powder injections for substances with poor stability in aqueous solutions.

Factories producing by-products

For example, sugar factories use their waste molasses to produce dry yeast, or further process them to produce nucleotide medicines.

Chinese medicine factory

Some well-known Chinese medicine factories in China (Table 2) have been developed on the basis of manual workshops in the form of front stores and back factories. Most of the remaining Chinese medicine factories have been established since the 1950s. The production of traditional Chinese medicine factories starts with traditional Chinese medicine materials, according to traditional Chinese medicine theory and traditional technology, processing and production of traditional Chinese medicines that can be taken directly, or modern dosage forms of injections, tablets, granules, granules, suppositories, aerosols, etc. Because the raw materials of Chinese medicine factories are agricultural and sideline products, most of them are harvested once a year. They are large and prone to mildew and deterioration. Their products, especially honey pills and plasters, are also prone to spoilage, deterioration, or worms and mites. Therefore, the Chinese medicine factory attaches great importance to mold and pest control in the storage of raw materials and products. In recent years, due to the use of modern production equipment, such as closed grinders, high-efficiency extraction equipment, membrane evaporators, spray dryers, and program-controlled coating machines, the production conditions and work efficiency have been greatly improved, product quality and production have been improved ability.
