Description

A kind of baking process of flue-cured tobacco cultivars cloud and mist 99
Technical field
The present invention relates to a kind of baking process of flue-cured tobacco, particularly a kind of baking process of flue-cured tobacco cultivars cloud and mist 99.
Background technology
Flue-cured tobacco is one of important measures of leaf tobacco production, and the fresh tobacco leaf of field results must could embody its excellent quality and higher commodity value by baking.At present, baking of flue-cured tobacco is promoted and is adopted intensive barn curing and use three-phase-drying for tobacco technique, and this technology comes from U.S.'s tobacco leaf main producing region, introduces China in eighties of last century middle nineteen nineties.After introducing, the main product cigarette district (as Yunnan, Guizhou, Hunan, Fujian, Henan etc.) in each main product cigarette district conducts extensive research and production practices at home, has now become main barn type and the baking process in each main product cigarette district.Flavescence, fixation, dry muscle three phases is divided into, yellowing stage by bake process; Dry bulb origin temp is 32-35 DEG C, temperature 36-38 DEG C between changing yellow stage, wet-bulb temperature 1-4 DEG C lower than dry-bulb temperature; The fixation stage: dry-bulb temperature 54-55 DEG C, wet-bulb temperature 38-40 DEG C; In the dry muscle stage: dry-bulb temperature 67-68 DEG C, wet-bulb temperature 40-42 DEG C, namely according to each stage tobacco leaf change requirement, set point of temperature humidity index, carry out heat supply and suitable ventilation, quality of tobacco is effectively embodied, and can integrate with international baking advanced level.
Tobacco flue-curing characteristic restricts by many factors such as kind, soil, weathers, and wherein most important factor is kind, and different flue-cured tobacco cultivars has different flue-cured tobacco characteristics.The new flue-cured tobacco varieties that cloud and mist 99 is Yunnan Academy of Tobacco Agricultural Science, Chinese tobacco breeding research (south) center adopts Yun yan85 and 9147 selection cross.At present, also there is no the report of the special baking process for this kind of cloud and mist 99, and cloud and mist 99 adopts traditional three-phase-drying for tobacco technique, after baking, upper medium grade cigarette ratio is only about 60.5%, it is high that middle and upper part tobacco leaf bakes red cigarette ratio, and reach more than 23.4%, upper tobacco leaf variegated cigarette ratio is large, reach more than 5.36%, the style characteristic of cloud and mist 99 can not be embodied.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of baking process of flue-cured tobacco cultivars cloud and mist 99, this technique is suitable for toasting cloud and mist 99 tobacco bred, thus improves outward appearance and the interior quality of cloud and mist 9.
Object of the present invention is achieved through the following technical solutions: a kind of baking process of flue-cured tobacco cultivars cloud and mist 99, and it comprises the following steps:
S1. temperature control on fire: after the shove charge of cloud and mist 99 tobacco leaf, igniting, is raised to 30 ~ 36 DEG C with the temperature changing speed of 1 ~ 2 DEG C/h by dry-bulb temperature, then with the temperature changing speed of 0.5 DEG C/h, dry-bulb temperature is raised to 37 ~ 40 DEG C, wet-bulb temperature 30 ~ 35 DEG C, steady temperature is to tobacco leaf blade tip flavescence 5 ~ 12cm;
S2. tobacco leaf turns yellow: the dry-bulb temperature of stove internal upper part tobacco leaf is risen to 35 ~ 40 DEG C, and wet-bulb temperature rises to 34 ~ 39 DEG C; The dry-bulb temperature of middle and upper part tobacco leaf in stove is risen to 38 ~ 42 DEG C, and wet-bulb temperature rises to 35 ~ 38 DEG C, steady Wen Zhilu mesonexine tobacco leaf turn yellow 8 ~ 9 one-tenths, wiltingly to fall down, high-rise tobacco leaf flavescence 6 ~ 7 one-tenth, blade are felt like jelly, and bottom lower tobacco leaf is pornographic movie blue veins;
S3. transition stage: the dry-bulb temperature of lower tobacco leaf in stove is risen to 42 ~ 46 DEG C, and wet-bulb temperature rises to 36 ~ 38 DEG C; Middle and upper part dry-bulb temperature in stove is risen to 42 ~ 44 DEG C, and wet-bulb temperature rises to 36 ~ 38 DEG C, steady Wen Zhilu mesonexine blade pornographic movie blue veins, the wilting hook point of high-rise blade;
S4. tobacco leaf fixation: the dry-bulb temperature of bottom in stove and middle and upper part is risen to 50 ~ 55 DEG C, and wet-bulb temperature rises to 36 ~ 40 DEG C, steady Wen Zhiquan a heatable brick bed tobacco leaf is dry;
S5. the dry muscle of tobacco leaf: the dry-bulb temperature of bottom in stove and middle and upper part is risen to 65 ~ 70 DEG C, and wet-bulb temperature rises to 40 ~ 43 DEG C, steady Wen Zhiquan a heatable brick bed tobacco leaf master pulse is absolutely dry.
Further, the heating rate in step S2, S3, S4 and S5 is 1 ~ 2 DEG C/h.
Further, in step S2, the baking of stove internal upper part tobacco leaf extends 25 ~ 30h, and the baking of middle part tobacco leaf extends 20 ~ 25h, and the baking of lower tobacco leaf extends 8 ~ 10h.
Further, in stove described in step S3, the baking of bottom and middle and upper part tobacco leaf extends 6 ~ 8h.
Further, in step S4, in stove, the baking of lower tobacco leaf extends 8 ~ 12h, and the baking of middle part tobacco leaf extends 13 ~ 18h, and the baking of upper tobacco leaf extends 8 ~ 12h.
The present invention has the following advantages: the present invention is on the basis of traditional tobacco leaf three-phase-drying for tobacco technique, creatively according to flue-cured tobacco cultivars cloud and mist 99 tobacco leaf characteristic and quality, the overall process of cloud and mist 99 top, middle part, lower tobacco leaf baking is divided into five step three phases according to the factors vary such as temperature, humidity, and according to each stage tobacco leaf change requirement, regulation humiture index, carry out heat supply and suitable ventilation, quality of tobacco is effectively embodied, and can integrate with international baking advanced level.The present invention has easy and simple to handle, security insurance, workable, can keep that tobacco leaf fixation is stablized, leaf-shrinkage degree is good, advantage that oil content and tobacco incense tolerance increase substantially.
The present invention is workable, can significantly improve the baking quality of tobacco of flue-cured tobacco cultivars cloud and mist 99 and first-class cigarette ratio, reduces roasting poor rate, after baking, upper medium tobacco leaf ratio improves more than 12.5%, and variegated cigarette ratio reduces more than 2.24%, and the blue or green ratio of the micro-band of middle and upper part tobacco leaf reduces more than 5.57%; The output value increases by more than 19.07%; Cured tobacco leaf gloss is bright-coloured, glossy, and chemical composition is tending towards coordinating, and sugared alkali ratio, nitrogen base ratio, total nicotine all meet former fuming composition quality evaluation criterion, can fully demonstrate cloud and mist 99 style characteristic.
