Continuous automatic baicalin extraction production process

Abstract

The invention discloses a continuous automatic baicalin extraction production process. The continuous automatic baicalin extraction production process comprises the following steps: step 1, soaking scutellaria baicalensis roots to obtain a leaching solution; and 2, respectively preparing a flocculant solution and an acidifier solution for subsequent use; step 3, adding the leaching solution and the flocculant solution into a continuous flocculation unit, and fully reacting to obtain a flocculation solution; and carrying out coarse separation on the flocculation solution to obtain primary separation liquid and sediment; and 4, carrying out fine separation on the primary separation liquid to obtain clarified liquid and flocculent mud; step 5, cooling the clarified liquid, and feeding the cooled clarified liquid into a membrane concentration unit to obtain a concentrate and sewage; step 6, acidifying the concentrate to obtain acidic crystal slurry; step 7, neutralizing the acidity of theacidic crystal slurry to obtain neutral crystal slurry; and step 8, filtering and drying the neutral crystal slurry to obtain baicalin. The process is high in automation degree, good in flocculation effect, stable in quality, small in loss of effective components, low in production cost, high in production efficiency and high in raw material utilization rate.

Description

technical field [0001] The invention relates to the technical field of plant extraction and medicine extraction technology, in particular to a continuous automatic extraction production process of baicalin. Background technique [0002] Scutellaria baicalensis is a traditional Chinese herbal medicine with a long history of application in my country. It was first recorded in "Shen Nong's Materia Medica". Baicalin is the main active ingredient of Scutellaria baicalensis, which belongs to flavonoids. The effect of the fetus. Scutellaria baicalensis-containing preparations are mostly used to treat upper respiratory tract infection and upper flu inflammation, so further development of scutellaria baicalensis planting industry and industrial extraction of baicalin have broad market prospects. [0003] At present, in the industrial extraction of baicalin, most of the traditional intermittent manual extraction methods are used. The processes are discontinuous, the labor cost is high...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to propose a continuous automatic extraction production process of baicalin, which solves the problem of unstable quality, serious decomposition loss of active ingredients, high labor cost, and large energy consumption during the extraction process of baicalin. Problems of low degree of operation automation and poor on-site sanitation
