Embodiment 1
[0022] 1) Select ginseng, remove its reed head, cut into 2-3cm sections, weigh 480 parts and put them into a heat reflux extraction and concentration unit, add 6 times the weight of 80% ethanol, heat to 40°C and soak for 2 hours. Turn on the heating system of the extraction tank, control the steam pressure of the jacket between 0.02 and 0.09MPa, and at the same time slightly open the condensed water outlet valve under the jacket to discharge waste gas and condensed water to maintain a constant steam pressure, and continue heating to bring the extract to boiling , open the secondary steam inlet valve that enters the condenser from the main tank, and close the secondary steam inlet valve that enters the condenser from the evaporator at the same time, open the condenser and cooler cold water inlet valves to carry out normal pressure cycle extraction for 20 minutes, then open the extractor The liquid medicine outlet valve, turn on the vacuum pump, the liquid medicine will be sucked...
Embodiment 2
[0029] 1) Select ginseng and remove the reed head, cut it into 2-3cm sections, weigh 480 parts and put it into a heat reflux extraction and concentration unit, add 7 times by weight of 90% ethanol and heat to 50°C for 3 hours. Turn on the heating system of the extraction tank, control the steam pressure of the jacket between 0.02 and 0.09MPa, and at the same time slightly open the condensed water outlet valve under the jacket to discharge waste gas and condensed water to maintain a constant steam pressure, and continue heating to bring the extract to boiling , open the secondary steam inlet valve that enters the condenser from the main tank, and close the secondary steam inlet valve that enters the condenser from the evaporator at the same time, open the condenser and cooler cold water inlet valves for atmospheric pressure circulation extraction for 30 minutes, and then open the extractor The liquid medicine outlet valve, turn on the vacuum pump, the liquid medicine will be suc...
