| titleOfInvention | Double-solvent extraction method |
| abstract | A double-solvent extraction method belongs to the technical field of extraction of effective components of animals and plants. The method is characterized in that: the method comprises the following steps: step 1) selecting two mutually insoluble extracting agents with different densities according to two effective components in the extracted material; step 2) adding materials into the leaching bin (3), and then adding an extracting agent with high density into the leaching bin (3) until the liquid level of the extracting agent is flush with the liquid inlet of the overflow pipe; step 3) closing the stop valve, opening the overflow valve (6), adding a certain amount of mixed liquid of the two extracting agents into the leaching bin (3), and starting the overflow pump (5) to extract the two effective components in the material; and 4) standing after extraction is finished, closing an overflow valve (6) after the extractant is layered, and opening a stop valve at the same time. The double-solvent extraction method simultaneously extracts two effective components in the material by using the mixed solvent, thereby greatly reducing the extraction time and improving the extraction efficiency of the effective components. |
