Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine extraction, in particular to a decolorization and filtering device for traditional Chinese medicine extract. Background Art

[0002] Traditional Chinese medicine extracts contain a large amount of impurities such as pigments, which need to be removed before purification and refining. At present, the decolorization methods of traditional Chinese medicine extracts mainly include alcohol precipitation, acid-base precipitation, adsorption, flocculation and membrane separation. Among them, the adsorption method is widely used due to its high decolorization efficiency; the adsorbents commonly used for decolorization of traditional Chinese medicine are mainly silica gel, alumina and activated carbon. These adsorbents do not react with active ingredients, so they also have the advantages of safety and reliability.

[0003] A decolorization and filtering device for Chinese herbal medicine extracts is disclosed in Chinese Patent Publication No. CN219907105U. The decolorization and filtering device for Chinese herbal medicine extracts fully contacts the Chinese herbal medicine extracts with an adsorbent through a stirring paddle, thereby accelerating the decolorization efficiency and reducing the decolorization time.

[0004] However, compared with the existing technology in the related field, since the position of the adsorbent holding cylinder is fixed, when the capacity of the Chinese medicine inside the decolorization barrel is large, the Chinese medicine needs to be stirred for a long time to ensure that the extract and the adsorbent are in full contact, which will result in a low decolorization efficiency of the device.
