However, with the changes in the market situation, the quality of the middle and upper tobacco leaves after roasting can no longer better meet the needs of the cigarette industry, which is mainly reflected in the following aspects: 1. The proportion of upper tobacco leaves is high, and the structure of the middle and upper tobacco leaves is slightly higher after roasting. Dense, thicker, darker in color, the characteristics of the upper leaf are more obvious, and the characteristics of the middle leaf are covered, and the grade of the middle leaf cannot be entered when purchasing, which affects the benefits of tobacco farmers. More importantly, the tobacco leaves after roasting cannot better meet industrial needs.
2. The total nicotine content of the upper tobacco leaves after roasting is too high, which cannot meet the market demand
3. The baking quality is not high, and the base is prone to blue and variegated after baking.
Affected by too many times of harvesting and 4-6 leaves in the middle and upper part of the mixed furnace, the ripening and curing period of tobacco leaves is delayed, the intensive curing process is difficult to formulate accurately, and the curing quality is not high

Embodiment 1
[0048] The method for intensively collecting and roasting the top 6-8 tobacco leaves comprises the following steps:
[0049] 1) The upper 6-8 leaves are fully mature at one time and harvested in two rounds: after the treatment of unsuitable tobacco leaves, the upper 4-5 leaves in the middle and the 2-3 leaves in the top are harvested respectively, and the upper 6 leaves are harvested separately. -8 leaves, 90-100% yellowing of the leaf surface, all the main veins are white and shiny, more than 2 / 3 of the branch veins are white, the angle between the stem and leaf is between 80-90°, the leaves are curved and arched, and the leaf surface is shrunken ;
[0050] 2) Tie pole:
[0051] Rod binding: lean the backs of the tobacco leaves, align the leaf bases, and expose 6 cm of the petiole, evenly distributed, two pieces per bundle, 70 bundles per rod, 140 pieces, 4-5 leaves in the middle, and the weight of a single rod is 8Kg. The top 2-3 leaves weigh 9Kg per pole;
[0052] 3) Fur...
Embodiment 2
[0061] Other steps are with embodiment 1, wherein step 2) is:
[0062] 2) Tie pole:
[0063] Rod binding: lean the backs of the tobacco leaves, align the leaf bases, expose the petiole by 7 cm, and distribute evenly, two pieces per bundle, 80 bundles of tobacco per rod, 160 pieces, 4-5 leaves in the middle and the weight of a single rod is 10Kg, The top 2-3 leaves weigh 11Kg per pole.
Embodiment 3
[0065] Other steps are with embodiment 1, wherein step 2) is:
[0066] 2) To smoke:
[0067] Tobacco clamping: discharge the tobacco leaves evenly, align the base of the leaf against the baffle of the operating table, insert the pins at a distance of 8 cm from the base of the leaf, weigh 11Kg per clamp for 4-5 leaves on the middle, and 13Kg per clamp for the top 2-3 leaves.

Abstract
The invention discloses a focus collecting and baking method of upper 6-8 pieces of tobacco leaves, belongs to the technical field of baking of the tobacco leaves and solves problems about poor overall quality of the baked tobacco leaves and too high total nicotine content of the tobacco leaves in the prior art. The method includes: performing two rounds of harvest at one step after full maturity of the upper 6-8 pieces of the tobacco leaves; performing rod tying and cigarette clamping; performing charging respectively; baking, namely adopting a medium upper tobacco leaf drying process on the middle and upper 4-5 pieces of the leaves, wherein the humidity is set to be 36DEG C in steady temperature of 42DEG C, the humidity is controlled to be 35DEG C in the temperature of 43DEG C to 46DEG C, the humidity is set to be 38DEG C in the temperature of 54DEG C, and the humidity is set to be 40DEG C in the temperature of 68DEG C; adopting a top tobacco leave baking process on the top 2-3 pieces of the leaves, wherein the baking time is set to be 50 hours in the steady temperature of 40DEG C, the humidity is set to be 36DEG C in the steady temperature of 42DEG C, the humidity is set to be 34DEG C in the temperature of 43DEG C to 46DEG C, the humidity is set to be 38DEG C in the temperature of 54DEG C, and the humidity is set to be 40DEG C in the temperature of 68DEG C; performing sorting. The focus collecting and baking method is suitable for collecting and baking of the tobacco leaves.
Description
technical field [0001] The invention relates to a method for intensively harvesting and roasting 6-8 upper tobacco leaves, belonging to the technical field of tobacco leaf roasting. Background technique [0002] The upper 6-8 tobacco leaves refer to the 6-8 tobacco leaves that are born on the top of the flue-cured tobacco after treatment with unsuitable tobacco leaves, including: 2-3 upper middle parts, 2-3 upper second sheds, and 2 top leaves , rather than the pure upper tobacco leaves divided by parts in the traditional sense. At present, the number of leaves that can be effectively harvested and roasted by a single flue-cured tobacco plant to meet the market demand is generally 15-18 pieces. Tobacco farmers usually harvest and roast in five times, namely: one furnace for the lower leaves, two furnaces for the middle leaves, and two furnaces for the middle and upper leaves. Two ovens. However, with the changes in the market situation, the quality of the middle and upper ...
