Description

Technical Field

[0001] The invention relates to the field of extraction equipment, in particular to a traditional Chinese medicine extraction equipment. Background Art

[0002] Chinese herbal medicine (English name: Chinese Traditonaldrug): Chinese medicine is mainly composed of plant medicine (roots, stems, leaves, fruits), animal medicine (viscera, skin, bones, organs, etc.) and mineral medicine. Because plant medicine accounts for the majority of Chinese medicine, Chinese medicine is also called Chinese herbal medicine. There are about 5,000 kinds of Chinese medicine used in various parts of China, and the prescriptions formed by combining various medicinal materials are countless. After thousands of years of research, an independent science has been formed - herbal medicine.

[0003] The chemical composition of traditional Chinese medicine is very complex. It contains multiple effective ingredients, ineffective ingredients, and toxic ingredients. Extracting the effective ingredients and further separating and purifying them to obtain effective monomers is an important part of traditional Chinese medicine research. At present, extraction technology has been widely used in this field. Traditional Chinese medicine is widely used in my country. It is usually necessary to extract the effective ingredients from the medicinal materials before taking them. Common methods of extracting traditional Chinese medicine include boiling, fumigation, etc.

[0004] Traditional boiling, fumigation and soaking methods usually involve soaking Chinese medicinal materials in solvents (such as ethanol and water) for a long time, relying on natural osmosis and diffusion to release the active ingredients.
