Embodiment 1
[0075] 200g of Xihuangcao raw material enters the countercurrent extraction equipment after being crushed, the raw material solvent ratio is 1:5, the water is preheated to 40°C and enters the countercurrent extraction equipment, the amount of cellulase added is 1g, the countercurrent extraction time is 2 hours, and the ultrasonic extraction tank is pre-installed Prepare 1000g of water and preheat it to 40°C. When residues enter the ultrasonic extraction tank, turn on the ultrasonic probe. The ultrasonic frequency is 40kHz. After 10 minutes, take out the extract at the bottom of the ultrasonic extraction equipment, filter and centrifuge to remove suspended particles, and then proceed. Pressurize to 3.0MPa and enter the membrane module. The reverse osmosis membrane with high interception performance for the active ingredients of Xihuangcao is selected in the membrane module. Under the pressure drive, the water passes through the separation membrane, and the active enzymes in the ...
Embodiment 2
[0079] 200g of Bletilla striata raw material is crushed and enters the countercurrent extraction equipment. The raw material solvent ratio is 1:5. The water is preheated to 40°C and enters the countercurrent extraction equipment. The total amount of cellulase and pectinase is 1g, the countercurrent extraction time is 2 hours, and ultrasonic extraction The tank is pre-filled with 1000g of water and preheated to 40°C. When residue enters the ultrasonic extraction tank, turn on the ultrasonic probe. The ultrasonic frequency is 40kHz. After 10 minutes, take out the extract at the bottom of the ultrasonic extraction equipment, and remove the suspension by filtration and centrifugation. The particles go backward and are pressurized to 3.0MPa to enter the membrane module. In the membrane module, the reverse osmosis membrane with high interception performance for the active ingredients of Xihuangcao is selected. Under the pressure drive, the water passes through the separation membrane...
