Embodiment 1

[0019] A method for bundling and baking loose flue-cured tobacco leaves of the present invention comprises bundling the tobacco leaves and putting them into a flue-curing room for baking. The baking process includes the following steps:

[0020] Early stage of yellowing: when putting the bundled tobacco leaves into the flue-curing room, place them upright on the stacking rack with the leaf tip facing upwards and the leaf base facing downwards. There are no gaps between bundles. Turn on the low-speed gear of the indoor fan in the barn, raise the dry bulb temperature to 33°C in 4 hours, keep the wet bulb temperature at 33°C, and bake at a steady temperature for 10 hours; The pollution-free cloth strips are bundled into small bundles with a diameter of 35 cm. The natural tightness is appropriate. The cloth strips are bundled at the third part from the leaf tip to the leaf base, and each bundle has 45 leaves. Different, 4kg~5kg per bundle.

Embodiment 3

[0039] A method for bundling and baking loose flue-cured tobacco leaves of the present invention comprises bundling the tobacco leaves and putting them into a flue-curing room for baking. The baking process includes the following steps:

[0040] Initial stage of yellowing: when putting the bundled tobacco leaves into the flue-curing room, place them upright on the stacking rack with the tip of the leaf facing up and the base of the leaf facing down. There is no gap between the bundle and the bundle. Turn on the low-speed gear of the fan in the flue-cured room, raise the dry bulb temperature to 34°C in 5 hours, keep the wet bulb temperature at 34°C, and bake at a steady temperature for 9 hours; The pollution-free cloth strips are bundled into small bundles with a diameter of 40 cm. The natural tightness is appropriate. The cloth strips are bundled at the third part from the leaf tip to the leaf base, and each bundle has 50 leaves. Different, 4kg~5kg per bundle.

Abstract

The invention provides a flue-cured tobacco loose-leaf bundling and curing method. The method comprises steps as follows: tobacco leaves are bundled and then placed in a flue-cured tobacco chamber for curing, and curing comprises steps as follows: the tobacco leaves are bundled and then placed in the flue-cured tobacco chamber; then, main veins of the tobacco leaves turn yellow and leaf apexes are dried at the early stage of color fixation; the tobacco leaves are dried at the later stage of color fixation; finally, the main veins of the tobacco leaves turn brown and are dried completely at the stem drying stage. The tobacco leaves are bundled and cured, so that the tobacco leaves are convenient to transport, loading and unloading speeds are high, the tobacco leaves are uniformly stacked, and about 20% of tobacco loading amount is increased; the tobacco leaves are uniformly heated with the reasonable curing method, lodging of the tobacco leaves is relieved during curing, and the cured tobacco leaves are better in expansion and contraction and can regain moisture easily. Proper heat supply and ventilation are performed at the reasonable dry-bulb temperature and the reasonable wet-bulb temperature, so that the appearance quality and the interior quality of the tobacco leaves are well guaranteed.

Description

technical field [0001] The invention relates to a method for baking loose flue-cured tobacco leaves, in particular to a method for bundling and baking loose flue-cured tobacco leaves, which belongs to the technical field of tobacco leaf preparation. Background technique [0002] With the continuous improvement of baking hardware facilities and the continuous improvement of baking technology, stacking and baking of flue-cured tobacco loose leaves has achieved complete success, which has played a positive role in reducing labor and cost for tobacco farmers and improving quality and efficiency. However, in the actual application process, due to the characteristics of the stacking and baking of flue-cured tobacco leaves, the cured tobacco leaves are prone to the phenomenon of "stiffness, smoothness, non-shrinkage, difficulty in regaining moisture, and slow down on the kang", which affects the quality of the cured tobacco leaves. Product quality. Contents of the invention [0...
