Embodiment 1

[0018] Put 100L of Reduning extract with a density of 1.30 at room temperature into the scraper concentrator 11, open the stirring paddle 9, then open the vacuum valve 6, when the value of the vacuum pressure gauge 2 reaches -0.06MPa, keep this pressure, open the condensation The cooling water valve 5 of the device 12 is opened, the steam valve 1 is opened, steam is introduced into the scraper concentrator 11, and the temperature in the scraper concentrator 11 is raised to 82°C, and the temperature is maintained for half an hour. After the timing is over, open the liquid outlet valve 3, start the screw pump 8, and form a flow cycle of the liquid medicine. The density of the traditional Chinese medicine liquid in the scraper concentrator 11 is measured online in real time by the mass flow meter 7 . Record the mass flow meter reading every minute, and open the sampling valve 10 to measure the real-time density with a standard density meter. After 10 minutes of timing, close the ...

Embodiment 2

[0023] Put 100L of Reduning extract with a density of 1.30 at room temperature into the scraper concentrator, turn on the stirring paddle 9, then open the vacuum valve 6, when the value of the vacuum pressure gauge 2 reaches -0.06MPa, keep the pressure and turn on the cooling water. Valve 5, open the steam valve 1, open the liquid outlet valve 3, start the screw pump 8, and form a liquid medicine circulation. The density of the traditional Chinese medicine liquid in the scraper concentrator 11 is measured online in real time by the mass flow meter 7 . When the temperature of the liquid medicine rises to 70°C, open the sampling valve 10, start to record data and take samples, take out evenly during the process from 70°C to 85°C, measure the real-time density with a standard density meter, record the reading of the mass flow meter 7 and the standard density meter Readings, recording process data as follows:

Abstract

The invention discloses a traditional Chinese medicine concentration process medicine liquid density on-line detection method. The traditional Chinese medicine concentration process medicine liquid density on-line detection method comprises following steps: (1) firstly, a liquid outlet valve of a scraper blade enricher in a traditional Chinese medicine concentration device is closed, a Chinese medical extract is delivered into the scraper blade enricher, a stirring paddle in the scraper blade enricher is turned on, a vacuum valve and a cooling water valve of a condenser are opened, a steam valve communicated with the scarper blade enricher is opened, and steam is delivered into the scraper blade enricher; (2) a liquid outlet valve of the scraper blade enricher is opened, and a screw pump is turned on so as to obtain medicine liquid circulation among the scraper blade enricher, the condenser, and the screw pump; and (3) a mass flowmeter is used for realizing real-time on-line determination of the density of the medicine liquid in the scraper blade enricher. The traditional Chinese medicine concentration process medicine liquid density on-line detection method is capable of realizing medicine liquid density real-time on-line detection of sphere / scraper blade concentration process, and can be used for medicine liquid density end point determination of sphere / scraper blade concentration process; automatic production is realized; and production efficiency and product stability are improved.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmaceutical technology, in particular to a traditional Chinese medicine scraper / spherical concentration process, in particular to an on-line detection method for medicinal liquid density in the traditional Chinese medicine scraper / concentration process. Background technique [0002] The traditional Chinese medicine scraper / spherical concentration process is a method used in the field of traditional Chinese medicine pharmaceuticals, and the density of the liquid medicine needs to be detected in the pharmaceutical process. At present, the density of the liquid medicine in the spherical / scraper concentration process of traditional Chinese medicine is difficult to be detected online, resulting in inaccurate process control and inability to accurately judge the density of the liquid medicine at the pharmaceutical end point. SUMMARY OF THE INVENTION [0003] The main technical problem to...
