[0002] The chemical composition of traditional Chinese medicine is very complex, containing multiple effective ingredients, ineffective ingredients, and toxic ingredients. Extracting its effective ingredients and further separating and purifying them to obtain effective monomers is an important part of traditional Chinese medicine research. Traditional Chinese medicine extraction is to use some technologies to extract the effective ingredients to the maximum extent, so as to improve the intrinsic quality and clinical treatment effect of traditional Chinese medicine preparations and maximize the effect of traditional Chinese medicine.

[0003] In the process of extracting traditional Chinese medicine, various traditional Chinese medicine materials are put into the traditional Chinese medicine extraction tank according to corresponding proportions for heating and steaming, so that the effective components of the traditional Chinese medicine materials can be extracted.
