Description

A biomedical grinding device

Technical Field

The utility model relates to the technical field related to biomedicine preparation, and specifically refers to a biomedicine grinding device.

Background technique

Most of the ingredients of biopharmaceuticals come from the rhizomes of herbs during preparation, and of course they can also be synthesized artificially. When extracting the active ingredients from botanicals, it is often necessary to refine the herbs first, and then steam them. After steaming, they are fractionated and extracted. When refining botanicals, a grinding device is required to grind the raw materials into powder or granules for subsequent processes. The existing grinding device has a simple structure, and generally grinds by driving the grinding disc to rotate with a motor. This can result in incomplete grinding and uneven particle size. When grinding some larger drugs, grinding will fail and the drug will get stuck. The grinding efficiency is low, resulting in average quality of the ground biopharmaceutical raw materials, which affects the extraction of biopharmaceuticals.
