[0040] Weigh fresh Cordyceps, w...
Embodiment 2
[0046] Embodiment 2 A kind of preparation method of dendrobium dry product mixture
[0047] Weighing medicinal materials according to the weight ratio of dendrobium, American ginseng and Cordyceps 5-15:5-10:3-9, and mixing to obtain a medicinal material mixture;
[0048] Use 6 times, 6 times, or 6 times the volume of ethanol to extract the medicinal material mixture by ultrasonic or warm soaking at a temperature of 45-65°C, combine the extracts, concentrate under reduced pressure to remove ethanol, and obtain the alcohol extract;
[0049] Add water to the residue at a weight ratio of 1:25-35, soak for 12-20 hours, pulverize into a slurry, centrifuge or filter, add water to the residue at a weight ratio of 1:15-25, soak for 1-2 hours, centrifuge or filter, and combine the extracts , to obtain the water extract;
[0050] Combine the concentrated alcohol extract and water extract, and concentrate at 20-40°C to obtain the extract.
Embodiment 3
[0051] The fresh product of embodiment 3 medicinal materials is made dry product
[0052] Freeze-drying of medicinal materials The fresh products or extracts of Dendrobium, American ginseng and Cordyceps are freeze-dried, and the specific steps are as follows:
[0053] 1) Cool the freeze-drying oven to -25°C, put the above medicinal materials in the freeze-drying oven at -20--25°C, and keep warm for 60-90 minutes to pre-freeze and keep warm;
[0054] 2) Before the end of pre-freezing and heat preservation, according to the cooling speed of the refrigeration compressor, the condenser (rear box) should be cooled to a temperature lower than -45°C in advance (in order to capture sublimation).
[0055] 3) Pre-evacuate, open the septum valve, and start sublimation drying (that is, the first stage of drying). When the vacuum degree reaches below 30Pa (can be determined according to the product requirements), keep it for 60-90min;
[0056] 4) In order to promote sublimation, the pro...
