Description
Technical field
The present invention relates to a kind of tobacco flue-curing house, especially a kind of flue-cured tobacco drying muscle stage uses the dense tobacco flue-curing house of low-temperature bake, belongs to
Tobacco modulation technique field.
Technical background
A seed type of the flue-cured tobacco (including fire-cured tobacco and fire tube indirect heating flue-cured tobacco) as tobacco, has there is centuries
History.Before more than 180 years, people start after finding that the purer perfume of tabacco fragrance that bakes of fire tube indirect heating is pleasant, people couple
Probing into for baking of flue-cured tobacco the relevant technologies just never stopped.Tobacco-leaf bulk curing barn is from 2008 in China's Large scale construction
Since, the hundreds of thousands of seats of bulk curing barn that the whole nation is built up and comes into operation have become the key facility of tobacco leaf modulation baking, especially
It, which is State Tobacco Monopoly Bureau in 2009 with domestic cigarettes, does comprehensive (2009) No. 418 texts " office, State Tobacco Monopoly Bureau is about printing and distributing
Since the notice of " curing equipment bid and purchase management method and bulk curing barn technical specification (tentative) revised edition " " is promulgated and enforced,
Tobacco-leaf bulk curing barn has received good effect according to normative construction, receives will be widely welcomed for each side.Bulk curing barn includes adding
Hot cell and cigarette-filling house, two rooms are separated by walls have ears, are equipped with circulation air path in the top and bottom of partition wall, logical using forcing
Wind can be divided into air-flow ascending manner and two kinds of airflow descending type compression according to the traffic direction of hot wind.
Baking process with baking facility often complement each other, it is interdependent each other mutually deposit, this has also been achieved as the prior art
Baking of flue-cured tobacco technique and can be realized the baking facility or barn of the baking process.
Now, global cured tobacco production and researcher, the overwhelming majority have got used to " using centainly since room temperature
Time, and certain ladder is set, temperature is gradually raised to 68 DEG C or so, meanwhile, with the rising of temperature and the passage of time,
The relative air humidity for being baked tobacco leaf water content and periphery is gradually decreased, whole bakings are finally completed " a kind of in this way Roaster
Skill and process curve.Make a general survey of this kind of baking process and curve, although they can because of various reasons (such as: country variant, no
With area, Different climate cigarette district, different cultivars or even different parts etc.) influence and difference, but also it is not difficult to find out that this
The similarity of baking process and curve is very high a bit, and the process curve tendency height of all of which is consistent.
With at present compared with there is the method for flue-curing tobacco leaves curve of representative as shown in table 1, the temperature in close relations with tobacco flue-curing
(dry-bulb temperature, wet-bulb temperature) and time, the two mutual cooperation complete entire baking process.We can be in baking process
Find out, the raising of passage and temperature at any time, baking process sequence press flavescence (dry-bulb temperature: firing temperature~38 DEG C, it is wet
Ball temperature: 35~36 DEG C), fixation (dry-bulb temperature: 40 DEG C~53 DEG C, wet-bulb temperature: 37~38 DEG C), dry muscle (dry-bulb temperature:
55 DEG C~68 DEG C, wet-bulb temperature: 40~41 DEG C) three periods are successively progressive, 68 DEG C are finally rested on until whole tobacco leaves (packet
Include mesophyll and vein) it is dry, that is, terminate tobacco flue-curing.The temperature range in above three period and each period is almost the whole world
Tobacco flue-curing is intended to the process of experience.
The conventional method for flue-curing tobacco leaves curve table of table 1
In table: Rh- relative humidity, the h- time, DEG C-Celsius temperature
It is numerous studies have shown that tobacco leaf enters barn after, the conversion and the two of the variation of appearance color and inherent substance
The fixation of (color, substance), two periods (changing yellow stage, fixation stage) have just been completed in front substantially.And 55 DEG C~68 DEG C phases
Between high temperature mainly promote the moisture in tobacco leaf master pulse to overflow, during this core of baking process be by raising dry bulb
Temperature (dry-bulb temperature is gradually increased to 55 DEG C~68 DEG C from 53 DEG C~54 DEG C of the fixation end of term), fine tuning wet-bulb temperature (wet-bulb temperature
40~41 DEG C are gradually increased to from 37 DEG C~38 DEG C of the fixation end of term), pass through the fortune of a large amount of heat supplies and ventilation aggravation tobacco leaf internal moisture
It moves and the relative humidity in barn between smoke stratification is promoted to be greatly lowered, prolonged high temperature and lower humidity is maintained to promote
Tobacco leaf is finally able to drying.
From it is found that fire tube heat supply can be with baking tobacco leaves after, above-mentioned baking process is just by vast cured tobacco production
Person and researcher are received, this is that the gravity-flow ventilation barn based on early stage is formed by technique.However, as forced ventilation is roasting
Room and the mechanical appearance that dehumidifies in recent years, it is this to divulge information by high temperature with a large amount of to have reached the finally dried baking process of tobacco leaf
It is no longer unique approach.
Especially, the dry muscle baking of this baking high temperature has following two aspects clearly disadvantageous:
1) dry muscle low efficiency, energy consumption are high, are kept for 68 DEG C of dry-bulb temperature or more be up to tens hours, at this moment due to barn
Interior relative humidity is relatively low, and dry-bulb temperature be higher by compared with ambient temperature (temperature, such as 25 DEG C) it is more,
It is obvious that the bring temperature difference is entered the wind when hydrofuge, in order not to reduce dry-bulb temperature, it is necessary to which a large amount of heat supplies lead to energy consumption height；
2) easily there is the reduction of tangerine color ratio example, color intensification phenomenon, reduce the ratio of first-class cigarette.
