Abstract

The invention discloses a flue-cured tobacco baking method for organic tobaccos and relates to flue-cured tobacco baking. The method comprises the following steps of: immediately closing the curing barn and air inlet after the tobacco recovery, scattered tobacco signing and filling and loading, maintaining the moisture of the tobaccos, and timely igniting and baking; baking at the stable temperature of 34 DEG C for 8-10 hours after ignition; raising the temperature, and baking at the stable temperature of 38 DEG C for 15-20 hours until the tobaccos turn 80 percent of yellow; raising the temperature, and baking at the stable temperature of 40 DEG C for 20-25 hours until the yellow tobaccos have blue veins; raising the temperature, and baking at the stable temperature of 46 DEG C for 10-20 hours until the tobacco veins turn white and the tobacco tips are dried; raising the temperature, and baking at the stable temperature of 52 DEG C for 25 hours until all the tobaccos are dried; and finally, continuously raising the temperature, and baking at the stable temperature of 68 DEG C for 25 hours until the tobaccos are dried. The method has the advantages that (1) the low-temperature yellowing time is reduced, and the material consumption is reduced so as to accelerate the yellowing of the organic tobaccos; (2) the humidity at the main yellowing period is improved, the yellowing of the tobaccos is accelerated, and the tobaccos can be fully yellowed; and (3) the whole yellowing time is shorter than that of the conventional tobaccos, and the production efficiency is improved.

Description

A kind of baking of flue-cured tobacco method of organic tobacco leaf
Technical field
The present invention relates to tobacco, relate in particular to the baking technology of tobacco leaf, relate in particular to the baking method of organic tobacco leaf.
Background technology
Organic tobacco leaf is the primary raw material source of the high-quality low harm cigarette product of cigarette industry enterprise production; With organic food favored pollution-free, characteristics such as quality is high, features good taste are identical; Develop organic tobacco leaf, produce organic cigarette and will help reducing the harm of cigarette product people.Organic leaf tobacco production, its ecological environment and production technology all have very big difference with conventional leaf tobacco production, and less relatively such as per mu yield, tobacco leaf is less, and the substance accumulation of tobacco leaf also has different with moisture.This has determined the baking technology and the also difference to some extent of conventional tobacco flue-curing technology of organic tobacco leaf.At present; The baking method of conventional cured tobacco leaf generally adopts syllogic baking technology and intensive baking technology, and the syllogic baking technology mainly is to be divided into 3 stages to the tobacco flue-curing process: changing yellow stage, fixation stage and drying muscle stage; 32 ℃~42 ℃ of changing yellow stage control temperature, 32 ℃~36 ℃ of wet-bulb temperature; 45 ℃~54 ℃ of fixation stage control temperature, 35 ℃~37 ℃ of wet-bulb temperature; 55 ℃~68 ℃ of drying muscle stage control temperature, 37 ℃~40 ℃ of wet-bulb temperature.Intensive baking technology mainly is stage intensification, steady temperature baking and a small amount of hydrofuge; Baking finishes when stage, is raised to the next baking stage with the programming rate that per hour is greater than or equal to 1 ℃; A baking cycle has main yellowing stage, main fixation stage and main dried muscle stage, wants foot in the time control of the steady temperature of this three phases.Organic tobacco leaf baking of flue-cured tobacco method and above two baking methods are different.
The baking technology application part that an organic tobacco leaf is only arranged in the Chinese patent; Be CN102640977A number " a kind of baking method that can effectively keep organic quality of tobacco ", this method comprises tobacco leaf picking, compiles bar dress cigarette, dehydration baking, wilting baking, cured leaf baking, cured leaf redrying, the redrying of muscle arteries and veins.Main feature is " heating up long insulation slowly ", and stoving time is long.But people still can improve the junior tobacco leaf quality in research and development, can shorten the technology of stoving time again.
Summary of the invention
The object of the present invention is to provide a kind of baking of flue-cured tobacco method of organic tobacco leaf, when improving the junior tobacco leaf quality, can also shorten stoving time, enhance productivity.
The baking of flue-cured tobacco method of organic tobacco leaf that the inventor provides, its tobacco leaf picking, dress cigarette operation are conventional technology, key problem in technology of the present invention is: after the dress a heatable brick bed finish, close barn door and air inlet immediately, keep moisture content in leaves, igniting baking in time; After the igniting, dry-bulb temperature rises to 33 ℃~35 ℃, and wet-bulb temperature is at 32 ℃~34 ℃, and steady temperature is toasted 8~10h; Speed with >=1 ℃/h is warming up to 38 ℃ then, 36 ℃ of wet-bulb temperature, and steady temperature baking 15~20h, most probably yellow to tobacco leaf; After this speed with >=1 ℃/h is warming up to 40 ℃~42 ℃, and wet-bulb temperature remains on 33 ℃~34 ℃, and steady temperature baking 20~25h is to tobacco leaf pornographic movie blue veins; Speed with >=1 ℃/h is warming up to 46 ℃~48 ℃ afterwards, 34 ℃~35 ℃ of wet-bulb temperature, and steady temperature baking 10~20h bleaches to the cigarette muscle, and blade tip is dry; Again, the speed with >=1 ℃/h under the situation that wet-bulb temperature is 35 ℃~36 ℃ is warming up to 52 ℃~54 ℃, keeps 36 ℃~37 ℃ of wet-bulb temperature, and steady temperature baking 20~25h is absolutely dry to blade; Programming rate with 1~2 ℃/h rises to 68 ℃ with dry-bulb temperature at last, and wet-bulb temperature remains on 39 ℃~40 ℃, dries until tobacco leaf.
Compare with syllogic baking technology and intensive baking technology, the present invention has following advantage:
1. reduce the low temperature flavescence time: organic tobacco leaf in process of production, dry-matter accumulation, moisture content in leaves are all less than conventional tobacco leaf, tobacco leaf is less.Reduce the low temperature flavescence time, quicken organic tobacco leaf flavescence to reduce the consumption of blade material.
2. improve main flavescence humidity in period: as 1 said,, improve 1 ℃ of tobacco leaf wet-bulb temperature period, guarantee relative humidity in the barn, quicken tobacco leaf flavescence and fully flavescence in main flavescence because the moisture of organic tobacco leaf is less relatively.
3. shorten the whole flavescence time: organic tobacco leaf is less, and substance accumulation is less relatively, and after the situation of change of organic tobacco leaf reached the requirement in each stage, programming rate got into the next stage immediately.The conventional tobacco leaf of the flavescence time ratio of organic tobacco leaf is very fast relatively, and the conventional tobacco leaf of flavescence time ratio shortens 8~10 hours, helps enhancing productivity.
The specific embodiment
Following examples can be explained the present invention better:
Embodiment: Guizhou Province in 2011 carries out the Fuquan City baked test of organic tobacco leaf
After tobacco leaf picking, dress cigarette finish, close barn door and air inlet immediately and keep moisture content in leaves, the igniting baking; After the igniting, dry-bulb temperature rises to 34 ℃, and wet-bulb temperature is at 34 ℃, and steady temperature is toasted 8h; Speed with 1 ℃/h is warming up to 38 ℃, 36 ℃ of wet-bulb temperature, and steady temperature baking 20h, after this speed with 1 ℃/h is warming up to 40 ℃; Wet-bulb temperature remains on 34 ℃, and steady temperature baking 20h is to tobacco leaf pornographic movie blue veins; Speed with 1 ℃/h is warming up to 46 ℃ afterwards, 34 ℃ of wet-bulb temperature, and steady temperature baking 15h bleaches to the cigarette muscle, and blade tip is dry; Again, be warming up to 52 ℃, keep 36 ℃ of wet-bulb temperature with the speed of 1 ℃/h, steady temperature baking 25h, absolutely dry to blade; Programming rate with 1.5 ℃/h rises to 68 ℃ with dry-bulb temperature at last, and wet-bulb temperature remains on 39 ℃, dries until tobacco leaf.
Result of the test shows that the conventional tobacco leaf of the flavescence time ratio of organic tobacco leaf shortens 8h.Presentation quality is better than organic tobacco leaf of other baking technology bakings after the tobacco flue-curing.It is thus clear that use this baking method, can solve the baking problem of organic tobacco leaf, improve the junior tobacco leaf quality.
