A kind of cleaning process of chicken feet coptis

Abstract

The invention discloses a cleaning process of Coptidis chinensis, comprising the following steps: a. Putting the sun-dried Coptidis japonica into a crusher for extrusion, so that the sediment mixed between the rhizomes and stems of Coptidis japonica is dropped, so as to obtain A. product, b, place product A on the vibrating screen to shake, and further remove the sediment on product A to obtain a finished product; the crusher is a jaw crusher; in the step b, the vibrating screen is a Linear automatic sieve or circular automatic sieve, the mesh size of the screen is 40 meshes; in the step b, the A product is shaken and then quickly passed through the water. In the invention, the sun-dried Coptis chinensis is squeezed by a crusher, so that the sediment between the roots and stems can be dropped, and then the vibrating screen is used to shake the Coptis chinensis, so that the residual sediment on the Coptis chinensis is fully vibrated. It was basically dropped, and finally passed through the water quickly, so that the sediment on the chicken feet Huanglian was completely removed. The invention has the advantages of high cleaning efficiency and high medicinal efficacy of the obtained coptis chinensis after cleaning.

Description

technical field [0001] The invention belongs to the field of pretreatment technology of Coptis chinensis, in particular to a cleaning process of Coptis chinensis. Background technique [0002] Coptis chinensis is shaped like chicken feet and can be used to make medicines or drinks. Its single rhizome is 3-6 cm long and 0.3-0.8 cm in diameter, with a rough surface, irregular nodular bulges, and fibrous roots and fibrous root residues. After the excavation of Coptis chinensis, there is a lot of sediment, and the heavy metal content in the sediment is high, which has harmful effects, so it is necessary to clean Coptis chinensis. [0003] The main active ingredient in Coptis chinensis is berberine. When the newly excavated Coptis chinensis is washed, the berberine will not be dissolved in water. When the sun-dried Coptis chinensis is cleaned, the berberine becomes easier to dissolve in water due to the changes in the tissue structure caused by the drying of Coptis chinensis, es...

Problems solved by technology

[0004] The existing cleaning method of Coptis chinensis is to break off the rhizomes of Coptis chinensis, manually remove the slag and sand between the rhizomes, and then wash with water. Therefore, the herb manor does not clean the Coptis chinensis, but directly dries, stores, and sells it. There are also a large number of dried Coptis chinensis in the market.

[0005] The processing factory of Coptis chinensis buys sun-dried Coptis chinensis. When cleaning, it is still necessary to split the rhizomes of Coptis chinensis and manually remove the slag and sand between the rhizomes. The efficiency is still very low. , moreover, berberine lost a lot of dissolved water at the fracture of fibrous root produced when the rhizome was opened, resulting in a low content of active ingredients in Coptis chinensis. After testing, the residual berberine in Coptis chinensis after cleaning was less than 27 %

[0006] Therefore, the existing cleaning method of sun-dried Coptis chinensis has the defects of low cleaning efficiency and low content of active ingredients in Coptis chinensis after cleaning.
