Material of Chinese medicine extracting process and apparatus thereof

Abstract

An apparatus for extracting active components from raw Chinese-medicinal material features that the first circulating loop is composed of extractor, pipeline, condenser and oil-liquid separator and the second circulating loop is composed of said first one, pipeline and circulating pump. Its process includes such steps as loading the raw Chinese-medicinal material in basket, putting it in extractor, filling solvent, heating by steam, extracting cyclically, condensing the aromatic oil vapor, oil-water separating, and reusing the separated solvent.

Description

technical field [0001] The invention relates to a process for extracting active ingredients contained in raw materials of traditional Chinese medicinal materials, and equipment for producing Chinese medicinal liquid by the process. Background technique [0002] At present, most domestic Chinese medicine factories are still using the water-liquid frying pan that has been used for nearly a thousand years as the traditional Chinese medicine extraction equipment, but a jacket is added to the bottom of the frying pan, and steam is passed into the coil pipe in the jacket for heating. Some manufacturers also use stainless steel multi-functional extraction tanks to carry out water or alcohol extraction of traditional Chinese medicine, supplemented by adding a stirring system on the top cover of the extraction tank for dynamic extraction, strengthening the mass transfer during the extraction process and increasing the heat exchanger circuit. , carry out reflux extraction operation. ...

AI Technical Summary

Problems solved by technology

These extraction equipment basically retain the characteristics of the traditional decoction process, but there are a series of problems such as large extraction coefficient, high impurity content, high energy consumption, low yield, insufficient extraction, inconvenient cleaning, and difficult separation of supernatant.

Since the feeding, discharging and the entire extraction process control of this type of equipment are still dominated by manual operations, the quality of the liquid medicine is greatly affected by human factors, and it is difficult to guarantee the quality of traditional Chinese medicine products.

In addition, some manufacturers adopt the percolation extraction process, which has a long operation period, a large amount of solvent, and high production costs, and still has the fundamental weaknesses of the traditional extraction process.

Nowadays, the vast majority of traditional Chinese medicine factories are producing small batches of multiple varieties, using intermittent operation for leaching, frequent turnover of production equipment, poor cleaning equipment, lack of necessary testing standards for cleaning effects, and a high possibility of cross-contamination of medicinal liquids
