Embodiment 1

[0024] Put 300,000ml of Jinqing extract with a density of 1.05 at room temperature into the scraper decompression concentrator 1, turn on the stirring paddle 2, turn on the steam valve 3, turn on the vacuum valve 4, close the vent valve 5, and concentrate normally.

[0025] After 20 minutes, open the vent valve 5, close the vacuum valve 4, close the steam valve 3, and close the stirring paddle 2. After returning to normal pressure in the scraper decompression concentrator 1, the liquid density is detected by the density meter 6, and the on-line Detection density.

[0026] Manually sample the medicinal liquid to obtain the offline detection density, continue to concentrate, and then repeat the detection of the medicinal liquid density every 10 minutes, and compare the online detection density with the offline detection density to prove the accuracy of the online detection density.

[0027] The online measured density in liquid medicine and the offline detection data are as foll...

Abstract

The invention discloses a Chinese medicinal scraper concentration device and an online liquid medicine density detection method. The Chinese medicinal scraper concentration device comprises a scraper pressure-reducing concentrator, a steam valve, a vacuum valve and a density meter, wherein the scraper pressure-reducing concentrator is provided with a steam conveying tube in a connection way; the steam valve is arranged on the steam conveying tube; the scraper pressure-reducing concentrator is provided with a first condensation liquid receiver in a connection way; a condensation pipeline is arranged between the scraper pressure-reducing concentrator and the first condensation liquid receiver for connecting; one side of the condensation pipeline is provided with a vacuum-pumping pipeline in a connection way; the density meter is arranged at the bottom of the scraper pressure-reducing concentrator and extends to the inner side of the scraper pressure-reducing concentrator; online detection is performed through concentration, detection and re-concentration. By adopting the Chinese medicinal scraper concentration device and the online liquid medicine density detection method, real-time online detection is realized, high detection accuracy is achieved, automatic production is realized, and the batch stability and product quality of a scraper concentration process are enhanced.

Description

Technical field [0001] The invention involves the field of medicinal liquid density detection, especially the concentrated device of Chinese medicine scraper and online detection method. Background technique [0002] During the concentration of traditional Chinese medicine scraping boards, the density of the drug is needed strictly, and the current problem of medicinal solution density measurement in the process of concentration of traditional Chinese medicine scraping board is needed. [0003] The conventional shutdown detection is consumed, and it is impossible to detect or measure online in real time, resulting in the difficulty of judging the end point of the scraper concentration process. It is not conducive to automated production.quality. Invention content [0004] The technical problem solved by the present invention is to provide a traditional Chinese medicine scraper concentration device and the density of medicinal liquid online detection methods to achieve concentrat...
