Tea fermentation method

The invention discloses a tea fermentation method, and relates to the technical field of fermentation engineering. The tea fermentation method comprises the following steps of: S1, picking fresh tea leaf shoots and leaves; S2, dehydrating the picked tea leaves, and performing enzyme deactivation; S3, conveying the tea leaves subjected to enzyme deactivation into a processing barrel, and performing rolling; S4, naturally drying the rolled tea leaves in the sun; and S5, picking and removing incomplete tea leaves to finish fermentation. According to the tea leaf fermentation method, the tea leaves are in contact with a barrier plate I and a barrier plate II through the gravity of the tea leaves when falling, so that the tea leaves are stressed and dispersed, the large clustered tea leaves are in contact with a connecting belt when falling, and the connecting belt is impacted to extrude a spring I, so that the large clustered tea leaves fall from two ends after being vibrated and dispersed; and therefore, large c
