abstract:
The invention discloses a method for extracting external medicinal materials by using micromolecule cutting technology, which comprises the following steps: grinding, crushing, wall-breaking and extracting the Chinese medicinal materials, and fully utilizing the raw materials. Ultrafine pulverization and cell wall-breaking technology cut herbs into small molecules that are easy to absorb. Supercritical carbon dioxide extraction technology can extract the effective components of Chinese herbal medicines efficiently and singly, and remove the residual organic solvents in raw materials.
Sovereign projects:
A method for extracting drugs for external use by using micromolecule cutting technology is characterized by comprising the following specific steps: (1) pulverizing drugs, adding solvent, grinding into slurry, and filtering to recover the slurry; (2) separating and recovering the solvent and solute in the filtrate, and carrying out ultra-fine crushing treatment on the separated solute with an ultra-fine pulverizer; (3) cell wall-breaking technology is adopted to break the cell wall of the ultra-fine ground solute; (4) putting the solute and entrainer after the wall-breaking treatment into an extraction kettle of a supercritical fluid extractor, wherein the flow rate of the supercritical fluid entering the extraction kettle is 30-40l/h, the temperature of the extraction kettle is 40-55 DEG C, the pressure is 30-32 MPa, and the extraction time of the supercritical fluid is 6-7 hours; (5) The fluid taken out of the extraction kettle enters the middle of the separation column, and the first-stage separation is carried out in the separation column 1; (6) the fluid passing through the primary separation column 1 enters the first separation kettle under stirring, and secondary separation is carried out in the separation kettle; (7) The fluid separated from the first separation kettle enters the second separation kettle under stirring.
