Problems solved by technology

[0005] Aiming at the shortcomings of the current intensive baking process, the present invention proposes a pre-withering intensive baking process, changing the traditional three-stage baking method into four stages, and adding a pre-withering stage before entering the curing room, which can It is a good solution to the problems of low smoke loading in dense curing rooms, high energy consumption for curing, high starch content of cured tobacco leaves and high proportion of variegated tobacco leaves, and improves the economic properties of cured tobacco leaves

Embodiment 1

[0023] Example 1: Tobacco leaves of Yunyan 87 from a certain production area in Hubei Province are baked by using the tobacco leaf pre-withering baking process in a dense curing room. The specific steps include:

[0024] (1) During the season of tobacco leaf curing, the collected fresh Yunyan 87 tobacco leaves were pre-withered on a shady hanging tobacco rack after being smoked through braiding rods or tobacco clips, resulting in 14.6% water loss of the lower tobacco leaves, The tobacco leaves are obviously soft; the middle tobacco leaves lose water by 12.1%, and the tobacco leaves are soft; the upper tobacco leaves lose water by 10.8%, and the tobacco leaves are soft;

[0025] (2) Move the Yunyan 87 tobacco leaves that meet the dehydration requirements after the pre-withering treatment in step 1 into the intensive curing barn, ignite the fire after being placed, and increase the temperature at a rate of 1 °C per hour to 38 °C and stabilize the temperature. The wet bulb temper...

Embodiment 2

[0029] Example 2 For the central tobacco leaves of Yunyan 87 in a certain production area in Hubei Province, the following two curing processes were adopted: T1 adopts three-stage curing (the existing conventional process), and T2 adopts the pre-withering intensive curing process (this paper) The process described in the invention), the energy consumption statistics of the roasting are carried out, and the economic properties, appearance quality, chemical composition and sensory quality of the roasted tobacco leaves are compared. The results are shown in Table 1-5.

Abstract

The invention provides a tobacco leaf prewilting baking process for a bulk curing barn. The tobacco leaf prewilting baking process for the bulk curing barn provided by the invention comprises the concrete steps of clamping the collected fresh tobacco leaves with a weaving pole or a tobacco clamp, prewilting on a shady tobacco hanging frame, so that the tobacco leaves meet prewilting requirement, then transferring the tobacco leaves into the bulk curing barn, and warming for twice to meet the yellowing requirement, wherein 2-3cm of apex of the tobacco leaves from a bottom shed to a middle shed is in an almost dry state; then warming for twice and baking until the tobacco leaves are dried into large winding drums and leaf blades are absolutely dry; and then warming at the speed of 0.5 DEG C per hour until the temperature is increased to 68 DEG C, controlling wet bulb temperature to be 42-43 DEG C, and maintaining rotating speed of a fan to be 720 revolutions until stems of the tobacco leaves are completely dry. By adopting the tobacco leaf prewilting baking process provided by the invention, tobacco leaf stacking capacity of the bulk curing barn is greatly increased, baking energy consumption is reduced, and the problem that starch content of the tobacco leaves after being baked and mixed colour tobacco proportion are high is solved, so that economic character of the tobacco leaves after being baked is improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a tobacco leaf pre-withering baking process in a dense barn that adopts a rod-hanging method or a tobacco clip method for loading tobacco. Background technique [0002] Tobacco curing is currently one of the weakest links in flue-cured tobacco production in my country, and the quality of curing directly affects the quality of cigarettes. The essence of tobacco leaf curing is the unity of the dehydration and drying process of tobacco leaves and the process of physiological and biochemical changes. Studies have shown that the closer the maturity is to the mature tobacco leaves, the easier it is to produce orange-yellow tobacco leaves with strong chroma, sufficient oil content, and loose tissue structure. The appearance quality of tobacco leaves reflects the quality of tobacco leaves to a certain extent. [0003] The tobacco curing rooms in the pr...
