Description

Leaf intensive barn curing baking process looses
Technical field
The present invention relates to the tobacco flue-curing technology, specifically, relate to the baking of flue-cured tobacco technology of the leaf intensive barn curing that looses.
Technical background
Existing baking of flue-cured tobacco technology mainly is meant conventional baking process.In recent years, in all parts of the country through test and popularization to intensive barn curing, make flue-cured tobacco concentrated type baking process technology perfect gradually.From 2002, ground such as domestic Heilungkiang, Guizhou, Hubei, Hunan were successively introduced Brazilian diffusing leaf barn and have been tested.Adopt the leaf intensive barn curing baking of loosing, because baking process is imperfect as yet, existing baking technology baking can only be adopted in many places, and problems such as thin, roasting saturating rate variance of cured tobacco leaf blade and roasting bad cigarette often occur, and have influenced applying of diffusing leaf intensive barn curing.Existing baking process comprises the operation requirement of the baking process of hanging the pole intensive barn curing, and some technical indicators can not be used for diffusing leaf baking.But at present relevant with tobacco flue-curing house baking process patent application is few, by retrieval, No. 200410061456.5 " fast energy-saving environmental protection dense tobacco flue-curing house and baking process thereof " is only arranged, but this patent application is for diffusing leaf baking and inapplicable.
Summary of the invention
The object of the present invention is to provide the leaf intensive barn curing baking process that looses, to solve the problem of the roasting saturating rate variance of tobacco leaf; Problem that solution cured tobacco leaf blade approaches, do not actuate and the problem that solves roasting bad cigarette.
The inventor points out the diffusing intensive baking of leaf after deliberation owing to adorn cigarette mode difference, and the required baking process of the variation of tobacco leaf in bake process must be adorned the cigarette mode with routine extension pole notable difference, and particularly the requirement to baking humidity has obvious difference.
The baking process of the diffusing leaf intensive barn curing that the inventor provides, mainly the baking stage comprises yellowing stage, fixation stage and dried muscle stage, also claims changing yellow stage, fixation stage and drying muscle stage.This technology is a kind of technology that adopts stage intensification to carry out tobacco flue-curing, and 1 ℃ speed heats up the temperature transition between thermograde per hour to be not less than, and mainly toasts steady temperature baking of stage at each; Whole bake process adopts flue-cured tobacco humiture automatic control system to control.
The controlled condition in the main baking stage of this technology is:
(1) yellowing stage: behind barn dress cigarette, igniting baking 15-20 hour; The flavescence initial stage, 32 ℃~35 ℃ of dry-bulb temperatures, steady temperature baking 10~25 hours is baked to and dry-bulb temperature is risen to 38 ℃ after the slight lodging of tobacco leaf and toast, and avoids tobacco leaf low temperature cirrhosis Huang, causes cured tobacco leaf not actuate; Yellowing stage, control dry-bulb temperature are 38 ℃, 35 ℃~36 ℃ steady temperature bakings of wet-bulb temperature, reach the pornographic movie blue veins when tobacco leaf changes, and when slightly falling down, temperature are controlled to be 38 ℃~40 ℃; In the flavescence later stage, before tobacco leaf was spoilt frame fully, earlier a small amount of hydrofuge toasted the fixation that heats up again after 10~15 hours.
(2) the fixation stage: low 1 ℃-2 ℃ of the more conventional baking technology index of fixation stage wet-bulb temperature control, avoid tobacco leaf sheet and roasting brown phenomenon to occur steaming; Specific practice is behind a small amount of hydrofuge of flavescence later stage, and temperature is raised to 46 ℃ to 48 ℃ by 38 ℃~40 ℃, and wet-bulb temperature is 34 ℃~35 ℃, toasts 12~15 hours; After the tobacco leaf master pulse feels like jelly flavescence, temperature is risen to 52 ℃~54 ℃, wet-bulb temperature remains 35 ℃~36 ℃; Keeping dry-bulb temperature is that 52 ℃~54 ℃, wet-bulb temperature are 35 ℃~36 ℃ steady temperature bakings, until the tobacco leaf drying.
(3) the dried muscle stage: the baking technology in dried muscle stage and conventional baking method are basic identical, mainly are low 1 ℃-2 ℃ of wet bulb humidity control.Specific practice is that temperature is raised to 60 ℃ by 54 ℃, and wet-bulb temperature is controlled to be 36 ℃~37 ℃, and air inlet can close to 1/2 or take the operation of automatic hydrofuge; After about 20 hours temperature is elevated to 65 ℃~68 ℃ in baking under 60 ℃ of temperature; Keeping dry-bulb temperature is 65 ℃~68 ℃, and wet-bulb temperature is 37 ℃~38 ℃ bakings, takes to control automatically hydrofuge, until tobacco leaf master muscle drying.
Above-mentioned temperature and humidity intelligent control system comprises the automatic instrument of humiture, Temperature Humidity Sensor, automatic temperature control and hydrofuge automaton.
The inventor points out, adopts the leaf intensive barn curing baking process that looses, and dress cigarette amount and tobacco loading method must reach the requirement of barn regulation, avoids the phenomenon that the cured tobacco leaf blade is thin, do not actuate.
Diffusing leaf intensive barn curing baking process of the present invention has solved the problem of the roasting saturating rate variance of tobacco leaf; Solved that the cured tobacco leaf blade is thin, the problem that do not actuate and the problem of roasting bad cigarette; Its advantage is: a whole set of baking process of perfect flue-cured tobacco, simplified the baking link; Greatly reduce the recruitment cost of baking link; This baking process can be used to hang the baking that pole mode and cigarette folder mode are adorned cigarette fully.
Description of drawings
Accompanying drawing is the intensification schematic diagram in diffusing leaf intensive barn curing each stage of baking process of the present invention.
