A method for extracting active ingredients of traditional Chinese medicine by water jet pulverization and centrifugal membrane decompression and low temperature distillation

Abstract

The invention relates to a method for extracting active ingredients of traditional Chinese medicine through water jet crushing and centrifugal membrane decompression and low-temperature distillation. Separator; S2, transporting the separated heavy matter to the water jet mill for water jet crushing; S3, transporting the light matter solution obtained in the step S2 to multi-layer disc centrifugal and gravity film forming and differential speed reducing The upper end of the low-temperature evaporator is a feed port, and the low-temperature evaporator includes rotating conical discs and fixed conical discs arranged coaxially and alternately stacked, wherein the revolving conical discs are fixed on the central axis for rotational movement; S4. The gas-phase active substance is sucked into the condenser together with the steam, and is condensed into a liquid together with the water vapor; then the active substance is separated from the condensed water through the separator to obtain the liquid active ingredient of traditional Chinese medicine. The invention realizes the high-quality active ingredients of the traditional Chinese medicine through pulverization and distillation extraction by a purely physical method.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, and more specifically relates to a method for extracting active ingredients of traditional Chinese medicine through water jet pulverization and centrifugal membrane decompression and low-temperature distillation. Background technique [0002] With the improvement of the health level of modern society and people's recognition of the concept of "returning to nature", more and more attention has been paid to medicines, food, health care and skin care products using natural plants as raw materials. Among them, traditional Chinese medicine has a unique and complete theory System, profound humanistic connotation, positive curative effect, no side effects and deeply loved by people. On the basis of inheriting traditional Chinese medicine processing technology and preparation technology, adopting new methods and new techniques to extract and utilize the active ingredients of Chinese m...

Problems solved by technology

This is a better way for the crushing of fibrous plants, but the problem is that the crushing process is accompanied by heat generation, which may cause the inactivation or deterioration of some biologically active components of traditional Chinese medicine

[0030] Based on the above analysis, it can be seen that in this field, there is no wet grinding process at present. The force application method of its pulverization not only has the effect of grinding and crushing, but also directly breaks the cell wall with stretching effect, and through Method for improving the saturated vapor pressure value of the solution film layer to realize low-temperature distillation and extraction of active ingredients of traditional Chinese medicine
