Traditional Chinese medicine alcohol precipitation technological process pH on-line detection method

Abstract

The invention discloses a traditional Chinese medicine alcohol precipitation technological process pH on-line detection method. The traditional Chinese medicine alcohol precipitation technological process pH on-line detection method comprises steps of equipment assembling, alcohol precipitation, cleaning, detection, and protection. More specifically, the traditional Chinese medicine alcohol precipitation technological process pH on-line detection method comprises following steps: a cylinder is operated; a pH meter detection probe is inserted into an alcohol precipitation tank; stirring is maintained, and on-line detection of drug liquid pH value is realized by using the pH meter probe; a pH adjusting agent is injected into the alcohol precipitation tank in batches by using a metering pump, and pH value of the drug liquid after each time of adding of the pH adjusting agent is detected; after pH value detection, the pH meter probe is removed out from the alcohol precipitation tank by using the cylinder, and is inserted into a pH meter protection cavity base body; a circulating pump is turned on so as to fill an inner chamber of the pH meter protection cavity base body with a KCl protection liquid. The traditional Chinese medicine alcohol precipitation technological process pH on-line detection method is capable of realizing drug liquid pH concentration real-time on-line detection of alcohol precipitation process, increasing working efficiency, and increasing stability of alcohol precipitation acid regulation processes and product quality; and it is beneficial for realization of automatic production.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine alcohol precipitation technology, in particular to an online detection method for pH of medicinal liquid during the traditional Chinese medicine alcohol precipitation technology. Background technique [0002] The alcohol precipitation production of traditional Chinese medicine has high requirements on the pH value and needs to be accurately grasped. However, the current pH value of the liquid in the alcohol precipitation process of traditional Chinese medicine mainly relies on manual liquid extraction for pH measurement. The work efficiency is low and it is difficult to realize automatic production. [0003] Manually taking liquid to measure the pH value is not only inefficient and affects the continuity of the traditional Chinese medicine alcohol precipitation process, but also leads to problems such as inaccurate control because the pH value of the liquid cannot be detected online in r...

[0002] The alcohol precipitation production of traditional Chinese medicine has high requirements on the pH value and needs to be accurately grasped. However, the current pH value of the liquid in the alcohol precipitation process of traditional Chinese medicine mainly relies on manual liquid extraction for pH measurement, which is inefficient and difficult to achieve automated production.

[0003] Manually taking liquid to measure the pH value is not only inefficient and affects the continuity of the traditional Chinese medicine alcohol precipitation process, but also leads to problems such as inaccurate control because the pH value of the liquid cannot be detected online in real time. It is difficult to judge the end point of the alcohol precipitation process, which affects the batch. Stability and Product Quality
