Abstract
Description
Technical Field
[0001] This utility model relates to the field of active pharmaceutical ingredients (APIs), specifically to a crystallization tank for the production of veterinary APIs. Background Technology
[0002] Active pharmaceutical ingredients (APIs) refer to the raw materials used in the production of various formulations. They are the active ingredients in these formulations and are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction, or biotechnology for medicinal use, but which patients cannot directly ingest. After heat processing, APIs need to be placed in crystallization tanks for cooling and crystallization to improve the purity of the finished drug.
[0003] In the process of extracting active pharmaceutical ingredients, in order to enable the active ingredients to exert their effects, it is usually necessary to extract and recrystallize the drugs. Traditional crystallization tanks often use water circulation cooling during crystallization, but water circulation cooling often has a high evaporation rate and uses a large amount of water.
