Subcritical low temperature extraction of medicina

The subcritical low temperature extraction equipment of Chinese medicinal materials is simply to extract the essence of traditional Chinese medicine by using the subcritical low temperature extraction equipment. The application scope of this equipment: preconcentration of Chinese medicine extract, concentration of Chinese medicine oral liquid, improvement of clarification and solubility of Chinese medicine granules, refining of standby liquid of Chinese medicine injection, medicine wine, etc.

Subcritical low temperature extraction equipment for Chinese medicinal materials
Subcritical low temperature extraction equipment of Chinese medicinal materials ingredients plays an increasingly important role in the field of medicine, which plays a positive role in improving the technical content of pharmaceutical products, promoting the automation of production process and the process of product quality standardization. Understand how the device works:
Put the medicinal materials into the subcritical low temperature extraction tank, and add 5 ~ 10 times the solvent of the medicinal materials, such as water, ethanol, methanol, acetone, etc. (according to the process requirements). Open the direct notification jacket steam valve of the subcritical low-temperature extraction tank, and make the subcritical low-temperature extraction liquid heated to boiling for 20 ~ 30 minutes, then pump 1/3 of the subcritical low-temperature extraction liquid into the concentrator with the suction filter pipe. Close the valve and concentrate begins. The secondary steam generated during concentration is fed into the subcritical cryogenic extraction tank as heat source and solution through the rising pipe of steam generator to maintain the boiling in the subcritical cryogenic extraction tank.
The secondary steam rises again and condenses into hot liquid through the condenser, then falls back to the sub-critical low-temperature extraction tank and is added to the drug surface as a new solvent. The new solvent passes through the medicinal material layer at high speed from top to bottom of the sub-critical low-temperature extraction tank, and the soluble effective components in the medicinal material are dissolved in the solvent in the sub-critical low-temperature extraction tank. Subcritical cryogenic extract through the suction filter tube and into the concentrator, concentration of secondary steam and sent to the subcritical temperature heat source and solvent extraction tank, thus formed a new solvent reflux subcritical extraction at low temperature, so the medicine in the concentrated mass density and solvents containing high solute density gradient, medicinal herbs of high solute instant, until complete dissolution (subcritical cryogenic extract colorless), this time, the subcritical cryogenic extract stop pumped in concentrator, enrichment of secondary steam transferred to cooler, concentrated again, until reduced to demand (1.2 ~ 1.34) ointment, release is used. The colorless liquid in the subcritical low temperature extraction tank can be put into the storage tank for approval, and the residue is discharged from the slag discharge door. If the subcritical low temperature extraction with organic solvent is used, the appropriate amount of water is added first, the steam is opened through the straight and the jacket is opened, and the residue is discharged after the solvent is recovered.

Subcritical low temperature extraction equipment for Chinese medicinal materials
Characteristics of subcritical low temperature extraction equipment for Chinese medicinal materials:
1. Single equipment, small footprint, high utilization rate of equipment, so the service capital is provincial.
2. Because the solute is dissolved quickly, the sub-critical low temperature extraction time is short, and the concentration and sub-critical low temperature extraction are carried out simultaneously, so it only takes 7 ~ 8 hours for the medicinal materials to concentrate the ointment, and the equipment utilization rate is high.
3. Subcritical cryogenic extraction only adds the solvent once, and is recycled in a set of sealing equipment. The solvent in the residue can be recovered basically.
4. Because the concentrated secondary steam serves as the heat source of subcritical cryogenic extraction, the subcritical cryogenic extraction liquid pumped into the concentrator is at the same temperature as the concentration, which can save more than 50% of the steam. The actual operation is very simple, and the actual operator is reduced.
5. Paste collecting rate is 10 ~ 15% higher than that of multi-energy tank, and the active ingredient in the ointment is more than 1 times higher. Because in the process of subcritical extraction at low temperature and hot of solvent on powder in a row, top-down, high-speed through the medicinal material layer dissolved solute in medicinal herbs, medicinal herbs containing dissolved in the content of solute and solvent quality to keep the high gradient, medicinal herbs of high solute instant, until completely dissolved out, are effective components subcritical cryogenic high extraction rate, concentration and completed in a set of sealing device, loss of small, high conversion rate, so the extract rate is high, the high content of effective ingredients in the ointment.
Chinese herbal medicine ingredients subcritical low temperature extraction equipment includes various Chinese herbal medicine subcritical low temperature extraction equipment, such as Schisandra chinensis subcritical low temperature extraction equipment, safflower seed subcritical low temperature extraction equipment, Magnolia officinalis subcritical low temperature extraction equipment.
