Embodiment Construction

[0052] The process of preparing Coptis rhizome micropowder by ultrafine pulverization method, the method adopts low-temperature dry method ultrafine pulverization method to prepare, specifically comprises the following steps:

[0053] (1) Raw material processing: grade the qualified Coptis chinensis medicinal materials, wash and dry, put the dried Coptis chinensis raw materials into a slicer for slicing, with a thickness of 1.5mm;

[0054] (2) Grinding: In the D-level clean area, the Coptis chinensis flakes processed in step (1) are crushed in an ordinary multi-functional grinder, and passed through a No. 2 sieve to obtain coarse powder.

[0055] (3) Sieving: Sieve the coarse powder through a Pharmacopoeia sieve and pass through a No. 5 sieve to obtain a fine powder with a particle diameter of 0.15 mm.

[0056] (4) Superfine pulverization: Put the obtained Coptis chinensis fine powder in a superfine pulverizer, occupying 2 / 3 of the material box, pulverize at -5°C for 12 minute...

Abstract

The invention discloses a technology of preparing rhizoma coptidis micro powder through a superfine grinding method and solves the problems that a traditional method has complex operating steps and is high in energy consumption and cost. The technology comprises the following steps of 1, treatment of a raw material, wherein the raw material rhizoma coptidis is put in a slicer and cut into slices, the thickness is 1-2 millimeters; 2, crush, wherein the rhizoma coptidis slices is crushed in a common multi-function crusher and screened with a number two screen to obtain crude powder; 3, screening, wherein the crude powder is screened with a pharmacopoeia screen, and passes through the number five screen to obtain fine powder, the diameter of the particles is 0.13-0.18 millimeter; 4, superfine grinding, wherein the obtained fine rhizoma coptidis powder is placed in an SQW turnover type superfine grinder, the fine rhizoma coptidis powder accounts for two thirds of a gland box, after the set temperature reaches -5 DEG C, grinding is conducted for 12 minutes, and the average particle size is 20-25 micrometers.

Description

[0001] The invention belongs to the processing of traditional Chinese medicines, and relates to a known processing technology of Chinese medicinal materials, in particular to a technology for preparing coptis chinensis micropowder by ultrafine pulverization. [0002] Background technique: [0003] Traditional mechanical crushing is the most widely used basic technology of traditional Chinese medicine processing. Compared with traditional Chinese medicine decoction pieces, it can increase the dissolution rate of active components, increase the bioavailability of Chinese medicinal materials, reduce the dosage of medicinal materials, and improve the utilization rate of medicinal materials. However, many medicinal materials contain aroma Sexual and volatile components, often these components are the active ingredients of medicinal materials, the traditional crushing technology takes a long time to crush, resulting in overheating, which will cause different degrees of volatilization l...
