Embodiment 1

[0020] This embodiment provides a method for curing the upper leaves of flue-cured tobacco, including:

[0021] 1) After collecting 6 leaves from the upper part of the flue-cured tobacco with 7-80% yellowing on the surface of the penultimate leaf, whitening of the main vein and branch veins, shedding of fluff, stem-leaf angle of 110-120°, and yellow-white mature spots, Cut off the stems at a position 5-8cm away from the lowest leaf position, and place them in a cool and dry place for 8 hours until the leaves become slightly soft.

[0022] 2) Tobacco is classified according to the degree of maturity, and the leaves of the lowest leaf position of the cut tobacco leaves are alternately left and right, straddling the tobacco rods, and tied with a braided tobacco rope. Each braided tobacco rod is used to weave 28 tobacco plants, with a spacing of 2-3cm .

[0023] 3) When loading cigarettes, install cigarettes in staggered layers between the upper and lower sheds, and the distance ...

Embodiment 2

[0030] This embodiment provides a method for curing the upper leaves of flue-cured tobacco, including:

[0031] 1) After collecting 6 leaves from the upper part of the flue-cured tobacco with 7-80% yellowing on the surface of the penultimate leaf, whitening of the main vein and branch veins, shedding of fluff, stem-leaf angle of 110-120°, and yellow-white mature spots, Cut off the stems at a position 8-10cm away from the lowest leaf position, and place them in a cool and dry place for 12 hours until the leaves become slightly soft.

[0032] 2) Classify and weave the tobacco according to the degree of maturity. The leaves of the lowest leaf position of the cut tobacco leaves are alternately left and right, spanning the tobacco rods, and tied with a weaving rope. Each weaving tobacco rod weaves 32 tobacco plants, with a spacing of 2-3cm .

[0033] 3) To load the cigarettes, when loading the cigarettes, install the cigarettes in staggered layers between the upper and lower sheds, ...

Embodiment 3

[0040] This embodiment provides a method for curing the upper leaves of flue-cured tobacco, including:

[0041] 1) After collecting 6 leaves from the upper part of the flue-cured tobacco with 7-80% yellowing on the surface of the penultimate leaf, whitening of the main vein and branch veins, shedding of fluff, stem-leaf angle of 110-120°, and yellow-white mature spots, Cut off the stems at a position 6-8cm away from the lowest leaf position, and place them in a cool and dry place for 8 hours until the leaves become slightly soft.

[0042] 2) Classify and weave tobacco according to the degree of maturity. The leaves of the lowest leaf position of the cut tobacco leaves are alternately left and right, straddling the tobacco poles, and tied with weaving ropes. Each weaving tobacco pole weaves 30 tobacco plants, and the distance between plants is 2-3cm. .

[0043] 3) When loading cigarettes, install cigarettes in staggered layers between the upper and lower sheds, and the distanc...

Abstract

The invention discloses a baking method for upper leaves of flue-cured tobacco. The baking method comprises the following steps: outbreak of a fire, a yellowing stage, a color fixing stage and a stem drying stage; and before baking, the material needs to be processed, including material collecting, tobacco weaving and tobacco filling. According to the invention, the baking condition of the upper leaves of the flue-cured tobacco can be controlled by controlling the heating rate and the temperature stabilizing time in baking, thus achieving an optimal effect. The baking method is capable of effectively reducing the labor strength in tobacco leaf harvest, promoting degradation and transformation of macromolecule substances in tobacco leaves, promoting the coordination of aroma substances and internal chemical components, improving aroma taste, reducing the ash hanging and stiffing proportion of upper leaves, and improving appearance quality.

Description

technical field [0001] The invention relates to a tobacco processing method, in particular to a method for curing the upper leaves of flue-cured tobacco. Background technique [0002] The upper leaves of the flue-cured tobacco include the upper second shed and the top leaf, a total of 6-7 pieces, accounting for about 40% of the tobacco plant output. High-quality top tobacco leaves with good maturity and coordinated internal chemical components are one of the important leaf group formulations in blended cigarettes and low-tar flue-cured cigarettes. Especially in recent years, with the advancement of cigarette tar reduction and harm reduction work in my country, the upper tobacco leaves with higher aroma concentration and slightly higher nicotine content have gradually become important raw materials to counteract the desalination effect of cigarette flavor brought about by the tar reduction process. . Therefore, high-quality upper tobacco leaves with good maturity are gradual...
