Puffing preparation method for raw material of Chinese herbl medicine

Abstract

The present invention provides a method for puffing Chiense medicinal material of normal temp. and high pressure, and it is used for pretreatment process of traditional Chinese medicinal materials, and its method includes the following steps: cutting Chinese medicinal materials, pressurizing at normal temp. and 1-20 MP and instantaneously releasing pressure so as to obtain the invented puffed material suitable for preparing preparation. Said invention uses the normal temp. compressed gas as medium which can be air, nitrogen gas or CO2 gas. Said invention can shorten the extraction time of the Chinese medicinal material, and can raise its production efficiency.

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 The methods are backward, the equipment is outdated, and the efficiency is poor and the level is low.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.
