Prevention and control method for reducing poison of alcohol and lactic acid in intensive tobacco leaf baking process

Abstract

The invention relates to a prevention and control method for reducing poison of alcohol and lactic acid in an intensive tobacco leaf baking process, which belongs to the technical field of blending of cured tobacco. The method comprises the following steps of: a, picking tobacco leaves in the morning of a clear day or rainless cloudy day, and not spraying water before the tobacco leaves are charged into a furnace; b, controlling tobacco loading density to be between 35 kg / m<3> and 45 kg / m<3>; c, controlling relative humidity of air in a curing barn to be between 90 percent and 75 percent and keeping the tobacco leaves at the temperature of 38 DEGC for 36 to 48 hours in a yellowing period; d, controlling the dry-bulb temperature to be between 51 DEG C and 53 DEG C and the wet-bulb temperature to be between 40 DEG C and 41 DEG C, and baking for 24 to 36 hours in a leaf drying period; and e, keeping a dehumidifying door slightly open by 2 to 3 percent in an entire tobacco leaf baking process, wherein the maximum opening of an air inlet door accounts for 70 percent of the total opening. In the method, other operating technologies are the same as those in the conventional baking method. The invention has the characteristic of low cost, easiness in learning, understanding and grasping, remarkable reduction in baking green smoke and black waste smoke, and increase in oil content of tobacco leaves, wrinkling degree and fragrance. The method is suitable for intensive tobacco leaf baking under different ecological environments in Chinese tobacco areas.

Description

Technical field: [0001] The invention relates to a prevention and treatment method for reducing alcohol and lactic acid poisoning in the intensive baking process of tobacco leaves, belonging to the technical field of tobacco preparation. Background technique: [0002] China's intensive barns have been promoted and applied to 510,000. The practice of baking has proved that the intensive baking room has the characteristics of large baking capacity, easy operation, and high rate of yellow smoke. [0003] However, the dense barn has changed the way of filling smoke in the traditional barn, and the density of smoke has increased significantly. The smoke density of ordinary barn is 20~25kg / m 3 , the smoke density of the dense barn is 40-50kg / m 3 . The smoke density is high, the gaps between the tobacco leaves are small, the air is scarce, and the oxygen content is reduced. Secondly, the dense tobacco barn has a large capacity to hold tobacco, and the living tobacco leaves con...
