Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with specific embodiments.

[0012] 2.3.1 Three-stage six-step baking process

[0013]

[0014] Note: The airflow descending barn, the change of tobacco leaves is mainly on the top layer

[0015] 2.3.2 Three-stage six-step baking operation technology

[0016] 2.3.2.1 Yellowing period

[0017] 2.3.2.1.1 The first step is to balance the temperature and humidity

[0018] After the fire started, the dry bulb temperature of the top table was raised to 35-36°C and the wet bulb temperature was adjusted to about 34°C at an average temperature increase rate of 1°C per hour, until the top table tobacco leaf ears turned yellow and the degree of yellowing of the tobacco leaves reached 5°C. -6 into yellow.

[0019] 2.3.2.1.2 The second step is to solve the yellowing of tobacco leaves

[0020] With an average temperature rise rate of 0.5°C per hour, the dry bulb temperature of the top table was raised from...

Abstract

The invention discloses a three-section six-step tobacco baking method. According to the method, a yellowing stage comprises the first step to the third step: first step: balancing the temperature and the humidity; second step: resolving the tobacco yellowing, and third step: resolving the branch vein yellowing; a color fixing stage comprises the fourth step to the fifth step: fourth step: resolving the main vein yellowing, and fifth step: increasing aroma substances; a stem drying stage comprises the sixth step of reducing the volatilization of aroma. The three-section six-step tobacco baking method disclosed by the invention obeys a moisture change rule, an oxidase activity change rule, a pigment change rule, a starch metabolism rule and a protein metabolism research result to couple four factors including the temperature, the humidity, the stable temperature time and the air speed of the tobacco; a baking key is provided with specific operation measures so as to be convenient for technical guidance and practical operation; the tobacco in the baking process is yellowed sufficiently, decomposed sufficiently and synthesized sufficiently so that the realization of the tobacco baking purpose is guaranteed.

Description

technical field [0001] The invention relates to a three-stage six-step tobacco leaf curing method. Background technique [0002] In recent years, with the popularization and application of dense curing rooms, the operation in the curing process has become easier and the work has been reduced significantly, which has played a huge role in improving the overall quality of Chongqing tobacco leaves. But there are still some problems in baking practice. The main manifestations are that the leaves contain green and the proportion of floating green in the main veins increases; the tobacco leaves hang ash and smooth; the tobacco leaf structure is relatively rigid; the chemical components of the tobacco leaves are not very coordinated, and the problem of insufficient aroma has not been well resolved. [0003] The characteristics of the curing process determine that the modulation process of tobacco leaves is partly decomposed and partly synthesized. Although the traditional baking ...
