Embodiment 1

[0023] Put 20000ml of antiviral extract with a density of 1.22 at room temperature into the alcohol precipitation tank, open the stirring paddle 11, and slowly add 95% ethanol. Turn on the alcohol precipitation liquid output pump 9, transfer the alcohol precipitation mixed liquid to the mixed liquid settling tank 2, filter through the filter plate 6 with a pore size of 120 μm, filter the medicinal liquid passing through the filter plate 6 through a filter screen 7 with a pore size of 90 μm, and pass through The medicinal liquid of the filter screen 7 is filtered through the 50 μm filter head 8 through the aperture, and when the medicinal liquid appears in the vent hole 5, the vent valve is closed, and the clear liquid enters the clear liquid measuring pool 3. Open the sampling valve 12, take a sample every 1 minute, measure its ethanol concentration with an ethanol concentration meter, and read the density of the corresponding clear liquid sample online in real time through the...

Embodiment 2

[0028] It is 30000ml of orange extract that the density is 1.25 at room temperature to put into the alcohol precipitation tank, open the stirring paddle 11, and slowly add 95% ethanol. Turn on the alcohol precipitation liquid output pump 9, transfer the alcohol precipitation mixed liquid to the mixed liquid settling tank 2, filter through the filter plate 6 with a pore size of 140 μm, filter the medicinal liquid passing through the filter plate 6 through a filter screen 7 with a pore size of 100 μm, and pass through The medicinal liquid of the filter screen 7 is filtered through the 60 μm filter head 8 through the aperture, and when the medicinal liquid appears in the vent hole 5, the vent valve is closed, and the clear liquid enters the clear liquid measuring pool 3. Open the sampling valve 12, take a sample every 1 minute, measure its ethanol concentration with an ethanol concentration meter, and read the density of the corresponding clear liquid sample online in real time th...

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 the alcohol precipitation process of traditional Chinese medicine, and relates to an online detection method for the ethanol concentration of medicinal liquid during the alcohol precipitation process of traditional Chinese medicine. Background technique [0002] The determination of ethanol concentration in the pre-alcohol precipitation process of traditional Chinese medicine generally adopts 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. Contents of the invention [0003] The purpose of the present invention is to provide an online detection method for the ethanol concentration of the medicinal liquid in the alcohol precipitation process of traditional Chinese medicine, so as to solve the problem that the etha...
