Description
Technical field
The present invention relates to tobacco flue-curing technical field, in particular to the mature flue-cured tobacco cultivars under rainy few sunshine condition
The tobacco flue-curing method of RG11.
Background technique
Baking is one of important measures of leaf tobacco production, and it is excellent that the fresh tobacco leaf of field harvest must could embody its by baking
Good quality and higher commodity value.Tobacco flue-curing characteristic is restricted by many factors such as kind, soil, weathers, wherein most heavy
The factor wanted is kind, and different flue-cured tobacco cultivars have different baking properties.Currently, baking of flue-cured tobacco technique is generally three-stage baking
Baking process is divided into flavescence, fixation, dry muscle three phases, yellowing stage by curing process: dry bulb origin temp is 32-35
DEG C, 36-38 DEG C of temperature during flavescence turns yellow and completes 40-42 DEG C of temperature, and wet-bulb temperature is 1-4 DEG C lower than dry-bulb temperature；Fixation rank
Section: 54-55 DEG C of dry-bulb temperature, 38-40 DEG C of wet-bulb temperature；The dry muscle stage: 67-68 DEG C of dry-bulb temperature, 40-42 DEG C of wet-bulb temperature,
Changed according to each stage tobacco leaf and is required, it is specified that temperature humidity index, carrying out heat supply and ventilation appropriate, quality of tobacco is had
Effect embodies, and can integrate with international baking advanced level.
Flue-cured tobacco cultivars RG11 is by A Erji seeds company of U.S. Cultivars, and Chinese Academy of Agricultural Sciences tobacco is ground within 1996
Study carefully introduced, passes through national tobacco evaluation committee in December, 1997 and assert.Currently, not yet specifically for flue-cured tobacco cultivars
The baking method of RG11, the especially baking method under rainy few sunshine condition are reported that addition flue-cured tobacco cultivars RG11 is adopted
With traditional three-phase-drying for tobacco technique, the baking property of flue-cured tobacco cultivars RG11 cannot be embodied.
Summary of the invention
The object of the present invention is to provide the tobacco flue-curing method of flue-cured tobacco cultivars RG11 of the maturation under rainy few sunshine condition,
Can preferably be withdrawn deposit the baking property of flue-cured tobacco cultivars RG11.
Above-mentioned technical purpose of the invention has the technical scheme that mature in rainy few sunshine condition
Under flue-cured tobacco cultivars RG11 tobacco flue-curing method, comprising the following steps:
(1) yellowing stage early period tobacco leaf is fitted into barn, is lighted a fire, rotation speed of fan remains 960r/min；So that dry bulb
Temperature is warming up to 34-36 DEG C, and wet-bulb temperature is warming up to 33-35 DEG C, and steady temperature 4-6 hours；It will be done with 1 DEG C per hour of heating rate
Ball temperature rises to 36-38 DEG C, and wet-bulb temperature rises to 34-36 DEG C；The steady warm tobacco leaf blade tip flavescence 3- to middle layer 90% in barn
4cm；It is transferred to yellowing stage mid-term；
(2) yellowing stage mid-term, rotation speed of fan remain 960r/min；Dry-bulb temperature is risen to 38-40 DEG C, wet-bulb temperature
It is raised to 37-39 DEG C, dry-bulb temperature is 1 DEG C higher than wet-bulb temperature, and steady temperature 4-6 hours；Wet-bulb temperature is reduced to 36-38 DEG C, dry bulb
Temperature is 2 DEG C higher than wet-bulb temperature, and steady temperature 4-6 hours；Wet-bulb temperature is reduced to 35-37 DEG C, dry-bulb temperature is higher than wet-bulb temperature by 3
DEG C, steady temperature turns yellow to middle layer tobacco leaf 1/2 in barn, and tobacco leaf feels like jelly；It is transferred to the later period that turns yellow；
(3) yellowing stage later period, rotation speed of fan remain 960r/min；Dry-bulb temperature is risen to 40-43 DEG C, wet-bulb temperature
It is warming up to 35-37 DEG C；Steady temperature is transferred to early period in fixation stage to the tobacco leaf pornographic movie blue veins of 80% or more middle layer in barn；
(4) early period in fixation stage, rotation speed of fan remain 1440r/min；Dry-bulb temperature is warming up to 45-47 DEG C, wet bulb
Temperature heats up 36-37 DEG C；Tobacco leaf turns yellow in steady Wen Zhiquan barn, and tobacco leaf offshoot turns yellow, and 80% or more tobacco leaf of middle layer is in
Now hook sharp phenomenon；Dry-bulb temperature is warming up to 48-50 DEG C, wet-bulb temperature is warming up to 36-38 DEG C；Middle layer tobacco leaf 80% in barn
The above small reel, is transferred to the later period in fixation stage；
(5) later period in fixation stage, rotation speed of fan remain 1440r/min；Dry-bulb temperature is warming up to 54-56 DEG C, wet bulb
Temperature is warming up to 38-40 DEG C；Steady Wen Zhiquan a heatable brick bed tobacco leaf is absolutely dry, is transferred to dry early period in muscle stage；
(6) dry early period in muscle stage, rotation speed of fan remain 960r/min；Dry-bulb temperature is warming up to 60-65 DEG C, wet bulb temperature
Degree is warming up to 40-42 DEG C；Steady temperature dries out to heat zone tobacco leaf master pulse 8 above, and cryosphere tobacco leaf master pulse 1/2 dries out, and is transferred to dry
Later period in muscle stage；
(7) dry later period in muscle stage, rotation speed of fan remain 960r/min；Dry-bulb temperature is warming up to 65-68 DEG C, wet bulb temperature
Degree is warming up to 41-43 DEG C；Steady Wen Zhiquan a heatable brick bed tobacco leaf master pulse is absolutely dry.
The further setting of the present invention are as follows: the temperature of dry bulb is small per steady temperature 4-6 at 38-40 DEG C in the step (2)
When, wet-bulb temperature is reduced by 1 DEG C, dry bulb steady temperature when 3 DEG C higher than wet-bulb temperature, until middle layer tobacco leaf 1/2 turns yellow in barn.
The further setting of the present invention are as follows: the step (2), (3), (4), (5), baking process in (6) heating speed
Degree is 0.5 DEG C/h.
The further setting of the present invention are as follows: in the step (5), when dry-bulb temperature is 54-56 DEG C, steady Wen Zhiquan a heatable brick bed tobacco leaf
After blade is absolutely dry, then extend baking time 8-12 hours.
The further setting of the present invention are as follows: entire baking process carries out auxiliary control using flue-cured tobacco temperature and humidity regimes
System adjusts the temperature and humidity in barn.
The invention has the following advantages:
1. mature tobacco leaf is unobvious in maturity period mature characteristic under the conditions of rainy few photograph, moisture content in leaves content is high, includes
Substance does not enrich, and blade is tender and crisp, and resistance to roasting property is poor, toasts misoperation, easily generation dust cigarette, black poor cigarette and steaming piece cigarette.Therefore,
On the basis of traditional tobacco leaf three-phase-drying for tobacco technique, according to flue-cured tobacco cultivars RG11 breediness and it is rainy it is few shine under the conditions of at
The competencies of ripe tobacco leaf, according to each stage tobacco leaf turn yellow and degree of drying requirement, it is specified that temperature and humidity index adjustment, into
Row heat supply and ventilation appropriate, so that rainy few according to the embodiment of tobacco leaves under condition stay in grade；
2. easy to operate, security insurance, strong operability can preferably be maintained at Mature Tobacco Leaves under the conditions of rainy few photograph
Style characteristic；
3. the technical solution strong operability of baking method, can significantly improve flue-cured tobacco cultivars RG11 baking quality of tobacco and
First-class cigarette ratio reduces variegated cigarette and green cigarette ratio, and after baking, upper medium tobacco leaf ratio is improved, and variegated cigarette ratio is reduced, tobacco leaf
Micro-strip blueness ratio is reduced, and per mu yield value increases, and cured tobacco leaf can fully demonstrate flue-cured tobacco cultivars RG11 style characteristic.
