Tobacco leaf baking method

Abstract

The invention discloses a tobacco leaf baking method, which comprises the following steps of: raising the dry ball temperature to 35+ / -1 DEG C, and maintaining the wet ball temperature at 33 to 34 DEG C until the tobacco leaf tops become yellow; raising the dry ball temperature to 38 to 40 DEG C at a speed being 1 DEG C in 2+ / -0.5 hours, prolonging the time after the temperature is stable, and controlling the wet ball temperature at 34 to 36 DEG C until the bottom layer tobacco leaves approach to or reach the state that yellow leaves account for 80 percent, green ribs become slightly yellow, and simultaneously, the leaves become soft; raising the dry ball temperature to 40 to 43 DEG C at a speed being 1 DEG C in 1+ / -0.5 hour, and maintaining the wet ball temperature being 36 to 37 DEG C so that all tobacco leaves at the bottom and partial tobacco leaves at the second layer become yellow and soft and are collapsed; raising the dry ball temperature to 54+ / -1 DEG C at a speed being 1 DEG C per hour, and simultaneously, gradually raising the wet ball temperature and stabilizing the wet ball temperature at 36 to 40 DEG C; raising the dry ball temperature to 68+ / -1 DEG C at a speed being 1+ / -0.5 DEG C per hour, stabilizing the temperature at the highest temperature not exceeding 70 DEG C until the tobacco leaves are completely dried; and simultaneously, stabilizing the wet bal temperature at 40 to 43 DEG C until the baking is completed. Through optimizing the tobacco leaf baking temperature control scheme, the tobacco baking quality can be improved, and the tobacco leaf baking cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco, in particular to a tobacco leaf curing method using a curing room. Background technique [0002] Tobacco leaf curing mainly includes soil room curing, three-stage curing and horizontal dense curing room, among which three-stage curing is widely used because it adapts to the small-scale scattered planting method of one family in my country. Three-stage curing refers to dividing the whole process of tobacco leaf curing into stages corresponding to the appearance state of tobacco leaves and the temperature requirements according to the organic relationship between changes in the appearance characteristics of tobacco leaves and the interior, that is, the yellowing stage, the color fixing stage and the tendon drying stage. [0003] The three-stage curing method is simple to operate, but in practice, the temperature and humidity of the curing room are relatively random, which directly affect...

[0003] The three-stage curing method is simple to operate, but in practice, the temperature and humidity of the curing room are relatively random, which directly affects the curing quality of flue-cured tobacco

The invention patent with the patent number "ZL02110188.4" discloses a "three-stage and five-step tobacco leaf curing process", which improves the traditional three-stage curing process, but there are still defects: on the one hand, the law of temperature rise is still If it is not enough, it affects the quality of tobacco leaf curing; on the other hand, the curing time is longer and the energy consumption is relatively large, which is not conducive to reducing the cost
