Problems solved by technology
However, the composition of traditional Chinese medicine is very complicated. Taking the extraction process as an example, the extraction liquid often contains solid particles such as traditional Chinese medicine particles. For the spectral detection of liquids, the solid particles in the liquid will cause light scattering, which will significantly affect the measurement. result
In addition, there are air bubbles in the extract, which will also affect the measurement results.
[0004] To sum up, if the offline method is used for analysis and detection, a certain amount of samples can be taken from the extraction tank (or reactor) and sent to the laboratory for fine sample pretreatment (such as pretreatment for high performance liquid chromatography analysis) , but this process takes a long time, and when the analysis results are obtained, the opportunity to adjust the process has been missed
However, due to the influence of various interference factors on-line direct detection, there is a certain deviation in the detection results.

The invention discloses a sampling system which is arranged on a reactor of a traditional Chinese medicine production line. The sampling system comprises a sampling pipe, a first pipeline, a second pipeline and a filtering device, wherein one end of the sampling pipe extends into the reactor and is used for taking out a sample in the reactor; the other end of the sampling pipe is connected with the first end of the first pipeline; the second end of the first pipeline is connected with a material inlet of the filtering device; a material outlet of the filtering device is connected with the first end of the second pipeline; the second end of the second pipeline is connected to the reactor; a sampling pump is arranged on the first pipeline; a check valve, a heater and a flowing basin for enabling a spectrometer to acquire spectrum data are sequentially arranged on the second pipeline from the first end to the second end. The sampling system disclosed by the invention can pretreat the taken-out samples during sampling at the same time, such as filtering and heating, so that interference on the samples can be eliminated, and the sample can be in proper states during detection.
Description
technical field [0001] The invention relates to a sampling system, in particular to a sampling and pretreatment system for on-line detection in the production process of traditional Chinese medicine. Background technique [0002] At present, the quality control of traditional Chinese medicine mainly adopts the method of release control, that is, the quality inspection of the final product is carried out, and it is put on the market if it is qualified, and it needs to be reworked or scrapped if it is not qualified. With the improvement of the international community's requirements for the quality of medicines, it is necessary to test the quality of intermediate products of traditional Chinese medicine production, and the testing technology is gradually strengthened. However, at present, the quality inspection of the production process of traditional Chinese medicine is still offline inspection of static materials or intermediate products, that is, after the production of a ce...
