Description
Technical field
The invention belongs to the method for baking of flue-cured tobacco.
Background technology
The modulation of flue-cured tobacco is the important step of cured tobacco production, is directly connected to the quality of flue-cured tobacco.Generally, flue-cured tobacco is to start annual late April to transplant, start baking mid-July, the time of toasting an a heatable brick bed is one week, add the moisture regain lower a heatable brick bed time, baking one a heatable brick bed tobacco leaf needs 10 days, one season flue-cured tobacco approximately to toast 7-8 a heatable brick bed, namely could finish baking by the end of September, 1000 meters of above high height above sea level cigarette districts could finish baking in early October.Enter after September, in " White Dew " of arriving in the agriculture twenty-four solar terms, temperature obviously declines, and day and night temperature is obvious, temperature on average is 20 ℃ of left and right, and field tobacco leaf is thicker, and leaf cell is tightr, moisture is more, and tobacco leaf can only reach physiological maturity, and still difficulty reaches technical maturity; If reach technical maturity, need 25 ℃ of above 3～5 days duration of constant temperature.Yet field tobacco leaf retention time is long easily bad again.If igniting baking immediately after tobacco leaf dress a heatable brick bed, moisture content in leaves is many, and dehydrating speed is slow, and hydrofuge is slow, easily roasting black, the measured tobacco leaf of difficult baking pledge, and after roasting, discarded tobacco leaf is more, causes tobacco grower's decline in benefits.
Baking of flue-cured tobacco has many processes, the technology of applying for a patent has: No. 200710077916.7 loose leaf intensive barn curing baking process > > of < <, belong to low humidity baking; Three section of five step formula intensive baking process > > of No. 201110406197.5 < < flue-cured tobaccos, for common extension leaf baking; No. 201210327964.8 loose leaf baking of < < flue-cured tobacco " three ladder seven footworks " > > are divided into three stages seven steps by flue-cured tobacco process to carry out.But these technical schemes can not solve the tobacco leaf baking problem that reaches physiological maturity and do not reach technical maturity.
Summary of the invention
The present invention aims to provide the stewing a heatable brick bed baking method of a kind of flue-cured tobacco, to utilize constant temperature, solves the tobacco leaf baking problem that reaches physiological maturity and do not reach technical maturity, promotes baking quality of tobacco object.
The present invention produces like this: in leaf tobacco production process in 2013, owing to being subject to 7-8 month prolonged drought climatic influences, after late August is rainy, cigarette strain upper tobacco leaf leaf water is more, difficult ripe, difficult baking, and easily bake black.Given this, inventor's investigation of going to the field, finds that tobacco leaf is thicker, and blade construction is tightr, and leaf water is many, has reached physiological maturity.By analyzing reason, find that entering September divides, mercury dropped is obvious, and day and night temperature is obvious, and because temperature is low, tobacco leaf only reaches physiological maturity, and tobacco leaf need to be adopted roasting, does not adopt for a long time and bakes with regard to rotten in vega.The time that hydrofuge needs in bake process is longer, is difficult to hydrofuge, and cured tobacco leaf poor flexibility, is prone to stiff blade and black-film.Find out after reason, sum up tobacco flue-curing experience, explore tobacco flue-curing method, sum up the condition that is suitable for tobacco leaf and be: tobacco leaf not only will reach physiological maturity, but also will reach the baking condition of tobacco leaf technical maturity, and Neither of the two can be dispensed.
The technical scheme that inventor adopts is: will reach physiological maturity and the tobacco leaf that do not reach technical maturity packs in barn, start firing up, ON cycle blower fan, allow the air in barn circulate under temperature constant state, i.e. " stewing a heatable brick bed ", allow tobacco leaf reach the state that in it, macromolecular compound easily decomposes, easily transforms, tobacco leaf reaches technical maturity from physiological maturity; Heat up and normally toast afterwards, by patent application, No. 201010144881.6 < < three-stage curing method for flue-cured > > operate.
In said method, the temperature under described temperature constant state is controlled at 30 ℃～32 ℃.
In said method, the described stewing a heatable brick bed time is controlled at 24～72 hours.
The physiological maturity of above-mentioned tobacco leaf refers to according to the definite maturity of tobacco growing time reckoning method, technical maturity refers to and reaches the needed technical conditions of baking, be that fresh tobacco leaf is difficult for fragmentation, slightly flexible, fresh tobacco leaf reaches the state that in it, macromolecular compound easily decomposes, easily transforms.
The inventive method has the following advantages: in the reduction of natural temperature condition, can not meet tobacco leaf and reach in the temperature required situation of technical maturity, adopt stewing a heatable brick bed baking, can impel tobacco leaf from physiological maturity, to reach the baking condition of technical maturity, toast out sound tobacco.Be applicable to that baking reaches physiological maturity and the tobacco leaf that do not reach technical maturity.
Accompanying drawing explanation
Fig. 1 is the tobacco leaf of the inventive method baking; Fig. 2 is the tobacco leaf of conventional baking method baking.
From upper two figure comparisons, can find out that the presentation quality of the tobacco leaf of the inventive method baking is obviously better than the tobacco leaf of conventional baking method baking: the tobacco leaf color and luster of stewing a heatable brick bed baking is even, good springiness, oil content is many; The conventional tobacco leaf toasting is more stiff, light, oil content is not enough (cromogram is obvious).
