Embodiment 1
[0027] A processing method of dendrobium officinale, comprising the following steps:
[0028] Step 1. Collect the Dendrobium officinale with strong plants and no pests, remove the fibrous roots and leaves, and wash it for later use; soak the cleaned Dendrobium officinale in a 4% potassium permanganate solution for 3 minutes, and then rinse the Dendrobium officinale with water. Drain again;
[0029] Step 2, placing the Dendrobium candidum drained in step 1 in a freeze dryer for freezing, and the Dendrobium candidum dropped from 25°C to -30°C in 1.5h;
[0030] Step 3. Dry the Dendrobium candidum after the quick freezing in step 2 under a vacuum degree of 20-40pa, and dry for the first time for 1h, and gradually increase the temperature from -30°C to -20°C; when the temperature rises to -20°C, carry out For the second drying, the drying time is 2 hours, and the temperature is gradually increased from -20°C to -10°C; when the temperature rises to -10°C, the third drying is carrie...
