3. Sorting: The processed Dendrobium is sorted according to its age, length, thickness, freshness and other qualifications, so as to control the heat in batches when frying.
4. Cleaning: Rinse the Dendrobium under running water again, then spread it out on a bamboo sieve or other utensils until the moisture on the surface of the stems is dry.
5. Stir-fry: Put the cooled Dendrobium stems into a 110℃-120℃ pot, stir-fry with bare hands for 20 minutes until the leaf sheaths open and the stems become soft.
6. Remove the sheaths and rub the fried stems of Dendrobium. Be gentle when removing the leaf sheaths to avoid damage or breakage of the stems.

10. hoop:Use flexible dragon beard grass to fix the two ends of the Dendrobium stem to prevent it from loosening and breaking during the fixing and winding process. The reason for using dragon beard grass is that it is soft and not easy to break, and has the characteristic of toughness.
11. Baking : Place the wrapped and hooped stems together with the stainless steel wire in a drying hopper and bake them. Use a medium heat of 70-80°C first, then a low heat of 30-50°C. Try to keep the baking even.
