Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine detection, in particular to an online detection system suitable for high-temperature traditional Chinese medicine liquid. Background Art

Furthermore, online detection devices can also discover potential process improvement points and optimization opportunities, promote process innovation and improvement, and help improve product quality stability and traceability, ensuring that products meet relevant quality standards and regulatory requirements. At present, the detection of intermediates or products mostly adopts the method of offline manual detection after sampling. The whole process is time-consuming and inefficient, and manual detection also has problems such as strong subjectivity, susceptibility to interference, and fatigue.

The device drives a square rod to rotate by rotating a handle, and the rotation of the square rod drives the rotation of a rotating shaft, and the rotation of the rotating shaft drives the rotation of a disc, and the rotation of the disc drives the rotation of a cylindrical rod, and the rotation of the cylindrical rod drives the rotation of a test tube, so that the Chinese herbal medicine liquid in the test tube is fully mixed, so that the online density detector can detect more accurately.

[0004] A Chinese patent document with publication number CN214011041U discloses an online detection and analysis system for the components of a Chinese medicine liquid, comprising: a liquid medicine sampling device, a filtering device, a defoaming device, a constant temperature device and an online detection device; the liquid medicine sampling device builds a bypass circulation path to extract a liquid medicine to be tested from a Chinese medicine extraction tank; the filtering device is arranged in the liquid medicine sampling path to filter the extracted liquid medicine to be tested; the defoaming device is connected to the filtering device to defoam the filtered liquid medicine to be tested; the constant temperature device is connected to the periphery of the defoaming device to maintain the temperature of the liquid medicine to be tested; the online detection device is connected to the downstream of the defoaming device to perform component detection and analysis on the constant temperature liquid medicine to be tested after filtration and defoaming using an online spectrum detection device, so as to obtain liquid medicine component information in real time.

In the above-mentioned process, online detection technology is used. Due to the problem of too high temperature of traditional Chinese medicine liquid, especially boiling liquid, if the detection is carried out directly, the sensor will be seriously damaged and the data obtained will not be accurate. In addition, solid particles often exist in traditional Chinese medicine liquid, which can easily interfere with the detection results. Utility Model Content
