Puffing preparation method for raw material of Chinese herbl medicine

Abstract

The invention provides a processing method of normal temperature and high pressure puffed Chinese herbal medicine, which is used in the pretreatment process of traditional Chinese herbal medicine preparations. The characteristics of this processing method are that the Chinese herbal medicine is chopped and processed under 1-20MP pressure at normal temperature, and the pressure is released instantly to obtain suitable Puffed products for preparations. The present invention uses compressed gas at normal temperature as the medium to accumulate gas molecules in the plant body of Chinese herbal medicine at high pressure, instantly reduces the external pressure, and utilizes the molecular kinetic energy generated by the release of high-pressure gas in the cells of Chinese herbal medicine to crush plant tissues and break plant cells in the high-pressure area. wall, or make plant tuber fibrosis in the low pressure area, the present invention can shorten extraction time, improve production yield, improve economic benefit when being used for extracting Chinese herbal medicine; The present invention adopts the air of different molecular masses, nitrogen, carbon dioxide Selective blasting of specific cell groups of traditional Chinese medicine plants rich in different medicinal ingredients under different pressures enables targeted bombardment of specific effective cells at the molecular level to achieve directional extraction of Chinese medicinal ingredients (single extraction), leaving a large space for research and development.

Description

technical field [0001] The invention relates to a processing method for expanding raw materials of Chinese herbal medicine preparations, and belongs to the technical field of pharmaceutical preparations. Background technique [0002] Traditional Chinese medicine crushing adopts methods such as cutting, pounding, grinding, grinding, and sieving. The methods are backward, the equipment is outdated, and the efficiency is poor and the level is low. The general processing fineness is 80-120 mesh, which cannot achieve the best purpose of extracting active ingredients. The extraction of traditional Chinese medicine generally adopts the method of decocting or extracting the decoction pieces. Because most of the rhizome medicinal materials have large tubers and it is difficult to extract the active ingredients in the deep layer, the decoction time is long, the active ingredients are greatly damaged, and the volatile useful substances are lost. The modernization of processing is impe...

Problems solved by technology

The extraction of traditional Chinese medicine generally adopts the method of decocting or extracting the decoction pieces. Because most of the rhizome medicinal materials have large tubers and it is difficult to extract the active ingredients in the deep layer, the decoction time is long, the active ingredients are greatly damaged, and the volatile useful substances are lost. Modernization of processing is imperative

[0003] At present, the modern methods for extracting the effective components of Chinese medicinal materials introduced in China include: supercritical apple extraction technology, membrane separation technology, distillation technology, resin adsorption technology, etc. No matter which extraction method is used, the Chinese herbal medicine needs to be crushed in the early stage, and the particle size of the crushing is relatively large. The extraction process is a very critical step. For example, the ultrafine pulverization technology currently used in the industry uses mechanical grinding and high-speed airflow collision to break the cell wall of Chinese medicine plants and extract more active ingredients of Chinese medicine. , material humidity brittleness, and impurities and other factors, the crushing effect is not ideal

In particular, the heat generated during the pulverization process has a large loss for volatile and low-melting effective substances, and insufficient pulverization of viscous substances.

Using the principle of puffed food, someone proposed a patent application with the application number of 94105630 "Chinese herbal medicine puffing processing method". A certain amount of water is added to the Chinese herbal medicine. Under high temperature and high pressure conditions, the water is instantly vaporized to make the medicinal material expand. It is more suitable for Chinese herbal tubers containing starch, but it is not effective for fibers or fruits or flowers and leaves. In addition, heating and puffing may damage the active ingredients of many medicines.
