Abstract

The invention relates to a curing method for increasing the yellowing speed of tobacco leaves at the upper part of Honghua Dajinyuan. The yellowing speed of tobacco leaves at the upper part of Honghua Dajinyuan is increased through starting and stopping a circulating fan in a bulk curing barn, the circulating fan in the bulk curing barn is adjusted to be in a low gear at which the air circulation rate is 140-160 m<3>/minute to enable the dry-bulb temperature in the curing barn to be increased to be 35 DEG C and the wet bulb temperature to be increased to be 35 DEG C, the dry-bulb temperature and wet bulb temperature in the curing barn are remained for 2-3 hours and then increased to be 38 DEG C and 37 DEG C respectively, the dry-bulb temperature of 38 DEG C and the wet bulb temperature of 37 DEG C are remained till tobacco leaves yellows by 80-90%, the circulating fan in the bulk curing barn is adjusted to be in a high gear at which the air circulation rate is 240-260 m<3>/minute, and the color fixation stage gradually starts. Compared with the conventional curing method, the curing method adopted for curing tobacco leaves of the Honghua Dajinyuan has the advantages that the yellowing time of tobacco leaves at the upper part of Honghua Dajinyuan can be shortened by 9.1 hours, the green tobacco rate is reduced by 4.7%, the ratio of surface dusting tobaccos is reduced by 5.3%, and economic benefit of each furnace is increased by 1074.31 yuan.

Description

Promote the baking method of Hongda upper tobacco leaf flavescence speed
Technical field
The present invention relates to a kind of method being promoted Hongda upper tobacco leaf flavescence speed by switch intensive barn curing Inner eycle blower fan, belong to tobacco flue-curing method.
Background technology
The large gold dollar of flue-cured tobacco cultivars safflower (being called for short red large) is the kind of generally acknowledged difficulty baking, the particularly upper tobacco leaf of this kind, toast difficulty especially large, still there is green grass or young crops point, blue veins and the dust of significant proportion in the upper tobacco leaf of red large kind in intensive barn curing, main cause is exactly that red large upper leaf dehydration is fast, flavescence is slow, just because dehydration too much paleness when a lot of tobacco leaf does not also turn yellow.
Summary of the invention
For the deficiency of above-mentioned existence, the present invention proposes a kind of baking method promoting Hongda upper tobacco leaf flavescence speed, by the improvement to existing baking method, namely by gauge tap intensive barn curing Inner eycle blower fan, effectively reduce blue smoke rate and dust cigarette ratio.
Existing baking method: the wind speed of intensive barn curing Inner eycle blower fan is fixing, rate of air circulation 190-210 cubic meters per minute.The present invention is achieved like this, Hongda upper tobacco leaf flavescence speed is promoted by switch intensive barn curing Inner eycle blower fan, after tobacco leaf installs, igniting, by the low or first gear of intensive barn curing Inner eycle Fan Regulation to rate of air circulation 140-160 cubic meters per minute, dry-bulb temperature in barn is made to be elevated to 35 DEG C and wet-bulb temperature 35 DEG C, dry bulb 38 DEG C and wet bulb 37 DEG C is warmed up to after stablizing 2-3 hour, stablize this temperature again and turn yellow 80-90% to tobacco leaf, regulate intensive barn curing Inner eycle blower fan to the top gear of rate of air circulation 240-260 cubic meters per minute, start progressively to enter fixation stage.
Adopt technical solutions according to the invention, the speed that Hongda upper tobacco leaf turns yellow is promoted by switch intensive barn curing Inner eycle blower fan, the method carries out the baking of the large gold dollar tobacco leaf of safflower, red large upper leaf can be shortened turn yellow 9.1 hours time compared with existing baking method, reduce blue smoke rate 4.7%, reduce dust cigarette ratio 5.3%, every stove increases economic efficiency 1074.31 yuan.
Detailed description of the invention
Embodiment one: after tobacco leaf installs, igniting, by intensive barn curing Fan Regulation to low or first gear (rate of air circulation 140 cubic meters per minute), dry-bulb temperature in barn is elevated to 35 DEG C, wet-bulb temperature 35 DEG C, stablizes this temperature and after 2 hours, be warmed up to dry bulb 38 DEG C, wet bulb 37 DEG C, stablize this temperature and turn yellow 90% to tobacco leaf, regulate blower fan to top gear (rate of air circulation 260 cubic meters per minute), start progressively to enter fixation stage.
Embodiment two: after tobacco leaf installs, igniting, by intensive barn curing Fan Regulation to low or first gear (rate of air circulation 150 cubic meters per minute), dry-bulb temperature in barn is elevated to 35 DEG C, wet-bulb temperature 35 DEG C, stablizes this temperature and after 2.5 hours, be warmed up to dry bulb 38 DEG C, wet bulb 37 DEG C, stablize this temperature and turn yellow 85% to tobacco leaf, regulate blower fan to top gear (rate of air circulation 250 cubic meters per minute), start progressively to enter fixation stage.
Embodiment three: after tobacco leaf installs, igniting, by intensive barn curing Fan Regulation to low or first gear (rate of air circulation 160 cubic meters per minute), dry-bulb temperature in barn is elevated to 35 DEG C, wet-bulb temperature 35 DEG C, stablizes this temperature and after 3 hours, be warmed up to dry bulb 38 DEG C, wet bulb 37 DEG C, stablize this temperature and turn yellow 80% to tobacco leaf, regulate blower fan to top gear (rate of air circulation 240 cubic meters per minute), start progressively to enter fixation stage.
