Embodiment 1

[0021] After the traditional Chinese medicine is crushed into coarse particles with a particle size of 200 mesh, it is injected into a superfine pulverizer together with freeze-dried air at a temperature of 0°C and a water content of 0.5%, and a high-speed airflow is used to prepare an ultrafine Chinese medicine powder with a particle size of 2500 mesh . The Miyou brand airflow mill was selected as the ultrafine pulverizer, the product model is QYF-260, the working pressure is 1MP, the internal working temperature is 8°C, and the pressure of the compressed air is 0.8MP. When the coarse particles of traditional Chinese medicine are ultrafinely pulverized, the airflow accompanied by ultrafine traditional Chinese medicine powder is filtered and collected by dust removal to make ultrafine traditional Chinese medicine powder.

[0022] Take out 1 / 5 of the ultrafine Chinese medicine powder and mix it into the original Chinese medicine powder for later use; fully dissolve the remainin...

Embodiment 2

[0032] After the traditional Chinese medicine is crushed into coarse particles with a particle size of 60 mesh, it is injected into a superfine pulverizer together with freeze-dried air at a temperature of 10°C and a water content of 1%, and a superfine Chinese medicine powder with a particle size of 1250 mesh is prepared by high-speed airflow . The Miyou brand jet mill was selected as the ultrafine pulverizer, the product model is QYF-260, the working pressure is 1.5MP, the internal working temperature is 3°C, and the pressure of the compressed air is 1MP. When the coarse particles of traditional Chinese medicine are ultrafinely pulverized, the airflow accompanied by ultrafine traditional Chinese medicine powder is filtered and collected by dust removal to make ultrafine traditional Chinese medicine powder.

[0033] Take out 1 / 3 of the superfine Chinese medicine powder and mix it into the original Chinese medicine powder for later use; fully dissolve the remaining superfine C...

Embodiment 3

[0037] After the traditional Chinese medicine is crushed into coarse particles with a particle size of 300 mesh, it is injected into a superfine pulverizer together with freeze-dried air at a temperature of 5°C and a water content of 0.1%, and a superfine Chinese medicine powder with a particle size of 12,500 mesh is prepared by high-speed airflow . The Miyou brand airflow mill was selected as the ultrafine pulverizer, the product model is QYF-260, the working pressure is 0.9MP, the internal working temperature is 10°C, and the pressure of the compressed air is 1.5MP. When the coarse particles of traditional Chinese medicine are ultrafinely pulverized, the airflow accompanied by ultrafine traditional Chinese medicine powder is filtered and collected by dust removal to make ultrafine traditional Chinese medicine powder.

[0038] Take out 1 / 4 of the ultrafine Chinese medicine powder and mix it into the original powder of traditional Chinese medicine for later use; fully dissolve...

Abstract

The present invention relates to a method for preparing Chinese medicine tablet preparation by adopting ultramicropulverization technology. Said method includes the following steps: raw material treatment, granulating, tabletting and coating, in which when the Chinese medicinal material is pulverized, the Chinese medicinal material can be pulverized into the crude granules with 60-300 meshes, then the crude granules are ultramicropulverized into the fine granules with 1250-2500 meshes, then dissolving these granules with solvent, filtering and taking out the filtrate. Said invention is small in table volume, high in medicinal effective component extraction rate and high in medicine utilization rate.

Description

technical field [0001] The invention relates to a method for preparing traditional Chinese medicine tablets by ultrafine pulverization technology. Background technique [0002] Chinese medicine tablet is a tablet preparation made of Chinese medicine fine powder or extract plus Chinese medicine fine powder or excipients. Affect the efficacy of the tablet. The traditional technology is to grind traditional Chinese medicine into fine powder for later use. The above-mentioned background technology has the disadvantages of long time-consuming process, low extraction rate of active ingredients, low drug utilization rate, and high waste of traditional Chinese medicine resources. Contents of the invention [0003] The object of the present invention is to provide a kind of method that prepares Chinese medicine tablet with superfine pulverization technology to overcome [0004] Insufficiency of existing technology. [0005] General id...
