Description

TECHNICAL FIELD

[0001] The utility model relates to the field of traditional Chinese medicinal material processing equipment, especially to a traditional Chinese medicinal material grinding device with screening and backflow functions. BACKGROUND

[0002] Traditional Chinese medicinal material grinding is the process of grinding traditional Chinese medicinal materials into fine powder. After the traditional Chinese medicinal materials are ground into powder, their surface area increases, which is beneficial to the absorption and utilization of drug ingredients by the body. This helps to improve the bioavailability of traditional Chinese medicine and accelerate the action of drugs in the body and promote the release of drug efficacy. Existing traditional Chinese medicinal material grinding devices are various, but their principles are basically similar. For example, a traditional Chinese medicinal material fine grinding device disclosed in patent CN217549899U mainly includes a workbench and a box body, and a grinding mechanism and a cleaning mechanism are arranged in the box body. The grinding mechanism and the cooperation between the structures in the grinding mechanism can fully crush and grind the traditional Chinese medicinal material raw materials. However, the grinding device of the above-mentioned patent has the following disadvantages: the ground traditional Chinese medicinal powder is of different thickness, and the coarser traditional Chinese medicinal powder needs to be ground again. Generally, manual screening or separate screening by a machine is used to separate the coarser traditional Chinese medicinal powder, which is then manually poured into the grinding device for regrinding or manually ground. This not only increases the labor intensity, but also reduces the screening and grinding efficiency. SUMMARY
