Description

A kind of intensive flue-cured tobacco technique
Technical field
The invention discloses a kind of intensive flue-cured tobacco technique, relate in particular to a kind of tobacco leaf product lover's who prepares intensive flue-cured tobacco technique.
Background technology
Baking of flue-cured tobacco is a link that is easy to cause mass loss, and the standard that the tobacco grower gathers to bright cigarette and requirement often have relatively large deviation, and estimating accurately the quality of bright cigarette and being worth does not have deep research and comparatively perfect standard.And in flue-cured tobacco process in enormous quantities, because the linking of each inter process and the timing node of each operation and the control of the duration and degree of heating are all the main causes of the final tobacco leaf product phase of impact.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of intensive flue-cured tobacco technique, has the advantages that to prepare tobacco leaf product lover.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of intensive flue-cured tobacco technique, its innovative point is to comprise the steps:
Step 1: tobacco leaf tie up processing, the rear fresh tobacco leaf of mainly gathering is classified and is tied up pole and process;
Step 2: the dress a heatable brick bed of tobacco leaf processed, and the fresh tobacco leaf of tying up after pole is processed evenly is positioned in the some frames in a heatable brick bed, and some frames is consistent up and down;
Step 3: the changing yellow stage of tobacco leaf is processed, and by the cold wind exhaust outlet of airtight a heatable brick bed after the dress a heatable brick bed, firing up, make temperature in a heatable brick bed rise to 36 ~ 38 ℃, opens the blower fan be connected with a heatable brick bed simultaneously; Then regulate and control the interior temperature constant of a heatable brick bed at 38 ℃, the dry bulb now arranged in a heatable brick bed and the temperature difference of wet bulb are controlled in 1 ~ 2 ℃, until 7 ~ 8 one-tenth flavescence of tobacco leaf, during, blower fan is per hour opened once, and each working time is 10min; Then regulate and control temperature in a heatable brick bed and be warming up to 42 ~ 44 ℃, and the temperature that maintains wet bulb in stove is at 38 ℃, until tobacco leaf is wilting;
Step 4: the fixation stage of tobacco leaf is processed, every 2 ~ the 3h of temperature on the basis of step 3 in the regulation and control a heatable brick bed heats up 1 ℃, until 48 ℃, the tobacco leaf master pulse now obtained is entirely yellow, then with every 1 ~ 2h, heat up 1 ℃, until be warmed up to 52~54 ℃, keep this interval temperature to be not less than 10h, now the interior wet-bulb temperature of stove is at 39 ℃;
Step 5; The drying muscle stage of tobacco leaf is processed, and controls wet and dry bulb temperature in a heatable brick bed so that per hour the speed rising of 1 ~ 1.5 ℃ is to 67-68 ℃, and wet-bulb temperature is stabilized in 40 ~ 43 ℃, until the tobacco leaf bone dry obtained, simultaneously to a heatable brick bed processing of ceasing fire;
Step 6: the moisture regain of tobacco leaf is processed, and opens blower fan, utilizes blower fan that moisture is sent in a heatable brick bed, and the moisture regain that completes tobacco leaf is processed.
Preferably, the moisture regain of step 6 tobacco leaf mainly comprises nature moisture regain or pressure moisture regain in processing, and moisture regain is mainly naturally: when air humidity is large in the morning, utilizing blower fan that extraneous air is sent in a heatable brick bed, is tobacco leaf humidification in a heatable brick bed; Force moisture regain to be mainly: when temperature drops to 40 ~ 45 ℃ in a heatable brick bed, in the heating clamber radiator on anti-, adding water, utilize blower fan that the moisture in heating clamber is delivered in a heatable brick bed, is tobacco leaf conditioning.
Preferably, in described pressure moisture regain, the ratio of amount of water and tobacco leaf is 1:5.
Preferably, described dry bulb and wet bulb are arranged at a heatable brick bed inner bottom part.
The invention has the advantages that: by adopting above-mentioned preparation process, strictly control each step link, thereby guarantee that the tobacco leaf obtained becomes chromaticity excellent mutually.
The specific embodiment
Intensive flue-cured tobacco technique of the present invention, comprise the steps: that the dress a heatable brick bed of tying up processing, tobacco leaf of tobacco leaf processed, the changing yellow stage of tobacco leaf is processed, the fixation stage of tobacco leaf is processed, the drying muscle stage of tobacco leaf is processed, the moisture regain of tobacco leaf is processed.
Tobacco leaf tie up processing, the rear fresh tobacco leaf of mainly gathering is classified and is tied up pole and process.
The dress a heatable brick bed of tobacco leaf processed, and the fresh tobacco leaf of tying up after pole is processed evenly is positioned in the some frames in a heatable brick bed, and some frames is consistent up and down.Concrete dress a heatable brick bed is treated to: guarantee that the levels frame is consistent during the dress tobacco leaf, the frame of same layer is evenly arranged along a heatable brick bed, is beneficial to Uniform Ventilation, and the levels frame is advisable apart from 12 ~ 15cm with pole.Lower floor's frame hangs the tobacco leaf that maturity is slightly higher.The tobacco leaf that natural environment humidity is large, moisture is higher, guarantee that this part tobacco leaf is placed in frame lower floor, and in frame, smoke filling density suitably reduces; More arid for weather, moisture content in leaves content is lower, and this part tobacco leaf is placed in the frame of upper strata, and smoke filling density can suitably strengthen.
The changing yellow stage of tobacco leaf is processed, and by the cold wind exhaust outlet of airtight a heatable brick bed after the dress a heatable brick bed, firing up, make temperature in a heatable brick bed rise to 36 ~ 38 ℃, opens the blower fan be connected with a heatable brick bed simultaneously; Then regulate and control the interior temperature constant of a heatable brick bed at 38 ℃, the dry bulb now arranged in a heatable brick bed and the temperature difference of wet bulb are controlled in 1 ~ 2 ℃, until 7 ~ 8 one-tenth flavescence of tobacco leaf, during, blower fan is per hour opened once, and each working time is 10min; Then regulate and control temperature in a heatable brick bed and be warming up to 42 ~ 44 ℃, and the temperature that maintains wet bulb in stove is at 38 ℃, until tobacco leaf is wilting.
The fixation stage of tobacco leaf is processed, and the every 2 ~ 3h of temperature continued in the regulation and control a heatable brick bed heats up 1 ℃, until 48 ℃, the tobacco leaf master pulse now obtained is entirely yellow, then with every 1 ~ 2h, heats up 1 ℃, until be warmed up to 52~54 ℃, keep this interval temperature to be not less than 10h, now the interior wet-bulb temperature of stove is at 39 ℃.
The drying muscle stage of tobacco leaf is processed, and controls wet and dry bulb temperature in a heatable brick bed so that per hour the speed rising of 1 ~ 1.5 ℃ is to 67-68 ℃, and wet-bulb temperature is stabilized in 40 ~ 43 ℃, until the tobacco leaf bone dry obtained, simultaneously to a heatable brick bed processing of ceasing fire.
The moisture regain of tobacco leaf is processed, and opens blower fan, utilizes blower fan that moisture is sent in a heatable brick bed, and the moisture regain that completes tobacco leaf is processed.
During wherein the moisture regain of tobacco leaf is processed, comprise the nature moisture regain or force moisture regain, moisture regain is mainly naturally: when air humidity is large in the morning, utilizing blower fan that extraneous air is sent in a heatable brick bed, is tobacco leaf humidification in a heatable brick bed; Force moisture regain to be mainly: when temperature drops to 40 ~ 45 ℃ in a heatable brick bed, in the heating clamber radiator on anti-, add water, the ratio of amount of water and tobacco leaf is 1:5, with blower fan, the moisture in heating clamber is delivered in a heatable brick bed, is tobacco leaf conditioning.
For accurately controlling the humidity in a heatable brick bed, dry bulb and wet bulb are arranged to a heatable brick bed inner bottom part.
