Description

[0002] Drugs refer to substances used to prevent, treat, and diagnose human diseases, purposefully regulate human physiological functions, and have prescribed indications or functional indications, usage, and dosage, including traditional Chinese medicine, chemical drugs, and biological products. The processing of atorvastatin calcium involves the extraction of raw materials for the production of atorvastatin calcium.

[0003] However, when the conventional extraction device performs mixed extraction on the raw materials and the extract for the production of atorvastatin calcium, the raw materials may adhere to the inner wall of the extraction box during the stirring process.

At the same time, when the raw materials for the production of atorvastatin calcium are extracted, the amount of the extract cannot be controlled. When the amount of the extract is small, the raw materials cannot be well extracted. When the amount of the extract is large, the extract will be wasted. Utility Model Content
