[0039] (1) Harvesting: 100 kg of buds and leaves are plucked from the buds and leaves of the associated tea trees of Dendrobium to avoid dew, rain, wind damage, insect damage, and diseases;
[0040] (2) Spreading: spread the picked tea leaves in a cool and ventilated place for 5 hours;
[0041] (3) Classification: the fresh leaves spread out are separated by size by a classifier, and the separated tea leaves are subjected to the following operations respectively;
[0042] (4) Kneading: Kneading the moderately withered fresh leaves, in order to ensure the excellent color, fragrance and quality characteristics of the tea leaves, the cold kneading method is adopted, and the kneading rate reaches 98% according to the pressing method of light and heavy;
[0043] (5) Deblocking and sub-sieving: the kneading leaves are deblocked to avoid the appearance of tea balls;
[0044] ...
Embodiment 2
