Embodiment 1
[0015] 1) Harvesting: Harvest 2-year-old Astragalus membranaceus when the plants wither in mid-to-late October. Choose sunny days after rain when the soil is relatively moist. Surround the plants by 30 cm and dig 70 cm deep with a hoe to keep the root bark intact and avoid damage to the root system. Yield and quality of medicinal materials. After excavation, shake off the soil and impurities, cut off the reed heads, remove fibrous roots, and remove rotten roots;
[0016] 2) Cleaning: Clean the fresh astragalus membranaceus with ultrasonic wave and water, the cleaning frequency is 20kHz, the cleaning power is 120W, the cleaning water temperature is 30°C, and the cleaning time is 5 minutes;
[0017] 3) Softening: Put the cleaned Astragalus membranaceus into a vacuum moistening machine, use a vacuum pump to depressurize and extract the air inside the container and the medicinal material for 30 minutes, so that all the air in the medicinal material tissue is extracted, and then int...

[0022] 1) Harvesting: Harvest the 3-year-old Astragalus membranaceus when the plants wither in mid-to-late October. Choose sunny days after rain when the soil is relatively moist. Surround the plants by 40cm and dig 90cm deep with a hoe to keep the root bark intact and avoid damage to the roots. Yield and quality of medicinal materials. After excavation, shake off the soil and impurities, cut off the reed heads, remove fibrous roots, and remove rotten roots;
[0023] 2) Cleaning: Clean the fresh astragalus membranaceus with ultrasonic wave and water, the cleaning frequency is 30kHz, the cleaning power is 240W, the cleaning water temperature is 40°C, and the cleaning time is 3min;
[0024] 3) Softening: Put the cleaned Astragalus membranaceus into a vacuum moistening machine, use a vacuum pump to depressurize and extract the air inside the container and the medicinal material for 40 minutes, so that all the air in the medicinal material tissue is extracted, and then introduce sa...
Embodiment 3
[0029] 1) Harvesting: Harvest Astragalus membranaceus that has grown for 3 years when the plants wither in mid-to-late October. Choose sunny days after rain when the soil is relatively moist. Surround the plants by 40cm and dig 80cm deep with a hoe to keep the root bark intact and avoid damage to the roots. Yield and quality of medicinal materials. After excavation, shake off the soil and impurities, cut off the reed heads, remove fibrous roots, and remove rotten roots;
[0030] 2) Cleaning: Clean the fresh astragalus membranaceus with ultrasonic wave and water, the cleaning frequency is 25kHz, the cleaning power is 180W, the cleaning water temperature is 40°C, and the cleaning time is 4min;
[0031] 3) Softening: Put the cleaned Astragalus membranaceus into a vacuum moistening machine, use a vacuum pump to depressurize and extract the air inside the container and the medicinal material for 35 minutes, so that all the air in the medicinal material tissue is extracted, and then ...
