Embodiment 1
[0049] 1. Withering: spread the fresh leaves evenly by 5cm on the withering curtain, and naturally wither for 19 hours at a temperature of 20°C and a humidity of 80%-85%. The stems are not easy to break, the leaves are dark green and dull, the grassy smell is reduced, and it has a pleasant fragrance;
[0050] 2. Kneading: The specific operation is that do not compact when throwing leaves, make it into a natural state and fill the kneading bucket, after adding the cover, knead for 5 minutes under the condition of no pressure, that is, air pressure, add light pressure and knead for 5 minutes, Knead with air pressure for 3 minutes, light pressure for 10 minutes, air pressure for 5 minutes, heavy pressure for 6 minutes, air pressure for 3 minutes, heavy pressure for 2 minutes, and air pressure for 20 minutes. The total rolling time is about 60 minutes, and the cell fragmentation rate is 80%.
[0051] 3. Fermentation: Evenly and loosely stack the rolled leaves in a dustpan with a t...
