Example Embodiment
[0015] Example 1
[0016] 1) Picking fresh leaves: Picking according to conventional methods, do not damage the leaves.
[0017] 2) Dipping: spray a potassium silicate solution with a concentration of 0.1 mmol / L on the picked fresh leaves. The material-to-liquid ratio of the fresh leaves to the potassium silicate solution is 100g:1ml.
[0018] 3) Withering: Use a withering trough to wither the leaves after immersion. After withering, the water content drops to 40%.
[0019] 4) Kneading: Put the withered leaves in a kneading machine and knead and twist them for 3 minutes.
[0020] 5) Fermentation: Put the kneaded leaves at 25°C for 2h fermentation.
[0021] 6) Drying: Dry the fermented leaves at 60°C to a moisture content of 4%.
Example Embodiment
[0022] Example 2
[0023] 1) Picking fresh leaves: Picking according to conventional methods, do not damage the leaves.
[0024] 2) Dipping: spray a potassium silicate solution with a concentration of 0.6 mmol / L on the picked fresh leaves, and the material-to-liquid ratio of the fresh leaves to the potassium silicate solution is 100g:5ml.
[0025] 3) Withering: the leaves after immersion are withered with sunlight. After withering, the water content drops to 48%.
[0026] 4) Kneading: Put the withered leaves in a kneading machine and knead and twist them for 10 minutes.
[0027] 5) Fermentation: Put the kneaded leaves at 28°C for 2.5 hours of fermentation.
[0028] 6) Drying: Dry the fermented leaves at 70°C to a moisture content of 5%.
Example Embodiment
[0029] Example 3
[0030] 1) Picking fresh leaves: Picking according to conventional methods, do not damage the leaves.
[0031] 2) Dipping: spray a potassium silicate solution with a concentration of 0.5 mmol / L on the picked fresh leaves, and the material-to-liquid ratio of the fresh leaves to the potassium silicate solution is 100g:3ml.
[0032] 3) Withering: the leaves after soaking are naturally withered indoors. After withering, the water content drops to 45%.
[0033] 4) Kneading: Put the withered leaves in a kneading machine and knead and twist them for 5 minutes.
[0034] 5) Fermentation: The kneaded leaves are fermented at 26°C for 2.2 hours.
[0035] 6) Drying: Dry the fermented leaves at 65°C to a moisture content of 4.5%.
