Abstract

The invention discloses a liquor ethanol concentration online detection method of a traditional Chinese medicine alcohol precipitation process. The liquor ethanol concentration online detection method comprises the following steps of firstly, pouring Chinese medical extract into an alcohol precipitation tank; starting an agitator blade; adding ethanol and mixing with the Chinese medical extract to obtain alcohol precipitation mixing solution; then starting an alcohol precipitation liquid output pump, transferring the alcohol precipitation mixing solution to a mixed solution settlement tank to obtain clear liquid after multi-stage filtering; transferring the clear liquid to a clear liquid determination pool; finally conveying the clear liquid to the alcohol precipitation tank by a clear liquid reflux pump to form a cycle; determining the density of the clear liquid in the clear liquid determination pool through an on-line densimeter online in real time; calibrating the concentration of ethanol in the clear liquid and the density of the clear liquid; building a corresponding function relation of the ethanol concentration and the density of the clear liquid in the clear liquid; and determining the ethanol concentration in the clear liquid through the corresponding function relation online in real time. Real-time online detection of the liquor ethanol concentration in the alcohol precipitation process is achieved; the liquor ethanol concentration online detection method can be applied to endpoint determination of the alcohol precipitation technology; and the batch stability and the product quality of the alcohol precipitation technology are improved.

Description

technical field

[0001] The invention belongs to the field of traditional Chinese medicine pharmaceutical technology, in particular to a traditional Chinese medicine alcohol precipitation process, and relates to an on-line detection method for the alcohol concentration of medicinal liquid in the traditional Chinese medicine alcohol precipitation process. Background technique

[0002] The ethanol concentration measurement in the alcohol precipitation process of the former traditional Chinese medicine generally adopts manual manual detection. During the detection process, it is easy to contaminate the liquid medicine, resulting in inaccurate measurement and affecting the quality of the liquid medicine. SUMMARY OF THE INVENTION

[0003] The object of the present invention is to solve the problems such as inaccurate control due to inaccurate control that cannot be detected on-line in the present alcohol precipitation process of traditional Chinese medicine, and provides a method...
