Explosion proof extraction and concentration unit

Working principle of explosion-proof extraction and concentration unit:

Put the medicinal herbs to be extracted into the extraction tank, and add a certain proportion of solvents such as water, ethanol, methanol, acetone, etc. according to the production process (add according to the process). Extract the raw material, and the extraction temperature can be set according to actual needs. Extract according to the production process. After the extraction is completed, open the pipeline valves in order and draw the liquid into the concentration tank for concentration. The temperature of the concentrated solution is set at the desired value, and the vacuum degree is maintained at -0.05 to -0.09MPA. The secondary steam generated during concentration is converted into condensate through the condenser and cooler and refluxed to the extraction tank as a new solvent to be added to the medicine. The new solvent flows from top to bottom through the medicinal layer to the bottom of the extraction tank. The soluble components in the medicine dissolve in the solvent in the extraction tank and are sent to the extraction tank as a new solvent to form a new solvent reflux extraction. The concentration continues until the required specific gravity ointment is obtained. The colorless liquid in the extraction tank can be reused next time.
