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 g...

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.
