A device for separating and purifying traditional Chinese medicine components by alcohol precipitation tank, its method and application

Abstract

The invention relates to the field of medicine production devices, in particular to a device for separating and purifying traditional Chinese medicine components in an alcohol precipitation tank, as well as its method and application. In order to solve the problems of uneven supernatant and incomplete removal of impurities in the prior art, the present invention proposes a device for separating and purifying Chinese medicine components in an alcohol precipitation tank and its method and application. By designing a serpentine tube in front of the density meter, When the precipitation supernatant flows through the serpentine pipe, the direction of the bend in the pipe changes abruptly, so that the solution is mixed evenly, which helps to improve the accuracy of the density meter detection. At the same time, due to a certain centrifugal effect at the elbow, the impurities have greater inertia than the solution and move downward against the outer wall of the elbow. At this time, a baffle is designed at the end of the elbow to help intercept impurities. At the same time, due to the blocking effect of the baffle, it cooperates with the elbow to realize further mixing of the liquid and improve the detection accuracy.

Description

technical field [0001] The invention relates to the field of pharmaceutical production devices, in particular to a device for separating and purifying traditional Chinese medicine components in an alcohol precipitation tank, a method and application thereof. Background technique [0002] The disclosure of information in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] In the alcohol precipitation process in the production process of traditional Chinese medicine, ethanol is mainly introduced into the extract at room temperature or low temperature for precipitation, and a large amount of high-concentration ethanol is added at the beginning of alcohol precipitation. If the alcohol content is too high, starch and proteins will rapidl...

AI Technical Summary

Problems solved by technology

[0004] However, the inventors have found that although the existing methods can remove impurities in traditional Chinese medicine components, the alcohol precipitation time is too long, which affects production efficiency

If the alcohol precipitation time is simply shortened, the solution discharged through the drain pipe cannot remove residual impurities or particles, which will not only affect the quality of the alcohol precipitation solution, but also cause certain damage to the density meter

Although some technologies regulate the purity of the outlet liquid through auxiliary devices (filters or filter screens), the filter or filter screen holes are prone to clogging, and the supernatant liquid after alcohol precipitation has a high viscosity, and it is difficult to pass through a fine-meshed filter screen. Larger, requires a larger vacuum pump to provide power, consumes a lot of energy, and has low production efficiency
