Method for applying biological enzyme in threshing and redrying links

The invention relates to a biological enzyme applying method for threshing and redrying links, and belongs to the technical field of tobacco redrying, the biological enzyme applying method for threshing and redrying links comprises the following steps: applying a biological enzyme preparation at a secondary moistening inlet, so that the tobacco leaves have reaction time after application, enzyme can be inactivated and excessive reaction can be prevented at the later stage, and the temperature at the secondary moistening inlet is less than or equal to 70 DEG C; the biological enzyme preparation is applied under the condition that the reaction time is smaller than or equal to 5 min, then the tobacco leaves are stored and fermented for at least 4 h in a formula cabinet, the sensory quality of the tobacco leaves is obviously improved, the texture and sweetness of the tobacco leaves are improved, the definition is good, smoke is clean, and the sensory quality of the tobacco leaves can be effectively improved when
