Description
Technical field
The present invention relates to the facility of baking tobacco leaves and baking process, particularly a kind of tobacco flue-curing house and method for flue-curing tobacco leaves.
Background technology
Weaknesses analysis for current tobacco flue-curing house and tobacco flue-curing：1st, common flue-cured tobacco baking room quality of tobacco out is low,
Can not meet the demand to High Quality Tobacco for the industrial Medicated cigarette, be mainly manifested in that oil is low, blade face is smooth, stiff, insufficient fragrance, chemistry becomes
Divide and not coordinate.The reason cause above except the characteristic of Nicotiana tabacum L. itself and artificial baking improper in addition to, mainly due to upper
There is the larger temperature difference, the speed that temperature raises simultaneously is faster, and the temperature difference between upper and lower two-layer Nicotiana tabacum L. is just between lower two-layer Nicotiana tabacum L.
Bigger, if bottom is more to the top layer Nicotiana tabacum L. number of plies in tobacco flue-curing house, then the temperature difference from bottom to top layer is bigger.Nicotiana tabacum L. is drying
There is a problem of in roasting process " surely temperature ", the Nicotiana tabacum L. to different layers is because have the temperature difference between levels residing temperature
Point just different, the thus harmony of the serious chemical composition that have impact on Nicotiana tabacum L., secondly, the another one of insufficient fragrance is former
Cause is that the wind speed design in tobacco flue-curing house cigarette-filling house is too high, and the aroma substance of Nicotiana tabacum L. is drained, the time longer aroma substance drained
More.2nd, the intensive flue-cured tobacco room Coal-fired capacity of the advanced energy-conservation of current domestic contrast is still high, and circulating fan power is big, runs consumption
Electricity is high, and baking time is long.The dry cigarette coal consumption often drying 1KG is 1.5KG～2KG, and the power consumption toasting every a heatable brick bed cigarette is about
250 degree, baking every a heatable brick bed cigarette time is 6 days～8 days.
Content of the invention
It is an object of the invention to provide a kind of tobacco flue-curing house and method for flue-curing tobacco leaves, solve current intensive flue-cured tobacco room and dry
Flue-cured tobacco oil is low, and blade face is smooth, stiff, insufficient fragrance and chemical composition problem of disharmony, and solves in baking process
Coal-fired capacity is high, and power consumption is big and the long problem of baking time.Because in tobacco flue-curing house between levels Nicotiana tabacum L. the temperature difference minimum even without
The temperature difference, so the Nicotiana tabacum L. in tobacco flue-curing house almost turns yellow simultaneously, dries simultaneously, and the time of baking is short, save energy, efficiency high.
The composition of the present invention：A kind of tobacco flue-curing house and method for flue-curing tobacco leaves, by exterior wall, inner wall, heater, shutter,
Maintenance door, moisture exhausting port, Yan Men, Temperature and Humidity Control instrument, return air inlet, circulating fan, air outlet, observation window, roof, cigarette frame,
Nicotiana tabacum L., dehumidifying passage, rain cover platform, extruded sheet heat-insulation layer and ground are constituted, and have and exterior wall about outer wall cavity in two
The parallel inner wall in termination, installs heater between exterior wall and inner wall, maintenance door be arranged on exterior wall and inner wall it
Between front exterior wall on, shutter is arranged on above maintenance door, and moisture exhausting port is arranged on top exterior wall and the Yan Men of cigarette door
On, or it is arranged on the lower section of rain cover platform, cigarette door is arranged on the middle front of exterior wall, and Temperature and Humidity Control instrument is arranged on cigarette
On the left side exterior wall of door, observation window is arranged on the right side exterior wall of cigarette door, or is arranged on the lower section of rain cover platform, cigarette frame
Be separately positioned between two inner walls, or be arranged between exterior wall and inner wall it is characterised in that：Inner wall sets
Put multiple return air inlets and multiple air outlet, between return air inlet and air outlet between alternating floor Nicotiana tabacum L. apart from cross arrangement, circulating fan
It is arranged in the air channel between heater and inner wall, a heater is respectively installed at the two between exterior wall and inner wall；
Described using this tobacco flue-curing house method for flue-curing tobacco leaves it is：
First, after heating, it is raised to 36 DEG C with 1 DEG C～2 DEG C of speed of dry bulb intensification in average 1 hour, error is less than 1 DEG C, does
Wet differ from 2 DEG C～4 DEG C, surely temperature 10～16 hours, Nicotiana tabacum L. reach 2～3 one-tenths Huang when, with l DEG C of speed of dry bulb intensification in average 1 hour,
Dry-bulb temperature is raised to 38 DEG C, dry and wet differs from 3 DEG C～6 DEG C, surely temperature 24～30 hours, when Nicotiana tabacum L. reaches 7～8 one-tenth Huangs, is put down with dry bulb
The speed of l DEG C of intensification in equal 1 hour, dry-bulb temperature is raised to 43 DEG C, and dry and wet differs from 5 DEG C～7 DEG C, surely temperature 12～24 hours, and Nicotiana tabacum L. reaches
Yellow, dehydration 50%～60%, master pulse deliquescing to 9.5～10 one-tenth；1., flexible governing factor, flexibly controls programming rate, usual rainy day
Cigarette, Haze, overdone cigarette, remaining green when it is due to become yellow and ripe cigarette or be in the relatively low cigarette district of height above sea level, heat up preferably fast, the cold stage before suitably shortening 38 DEG C,
And tobacco, thick cigarette, proper mature (ripe) cigarette, be in the higher cigarette district of height above sea level, heat up preferably slow, corresponding extend 38 DEG C before cold stage；2., flexibly
Control dry and wet poor, not high to quality, be easy to roasting black fresh cigarette, it is poor to widen dry and wet, so can prevent " cirrhosis Huang " phenomenon, right
Quality is higher, have the fresh cigarette of roasting blue or green tendency, and it is poor to reduce dry and wet, so can prevent roasting blue or green phenomenon；
2nd, in 43 DEG C of dry bulb, surely temperature reaches after flavescence requires Nicotiana tabacum L., and heated up 1 DEG C of speed with dry bulb for average 1 hour, uses
Dry-bulb temperature was raised to 53 DEG C by 43 DEG C in 10 hours, surely, it is ensured that full a heatable brick bed Nicotiana tabacum L. dry tablet, wet bulb temperature is stably for temperature 16～24 hours
It is maintained at 37 DEG C～40 DEG C；
3rd, Nicotiana tabacum L. is after surely temperature reaches dry tablet requirement for 53 DEG C of dry bulb, then 1 DEG C of the speed of being heated up for average 1 hour with dry bulb,
With 12～17 hours, dry-bulb temperature is raised to 65 DEG C～70 DEG C by 53 DEG C, with 65 DEG C～66 DEG C, middle part Nicotiana tabacum L. uses 67 to lower tobacco leaf
DEG C～68 DEG C, with 69 DEG C～70 DEG C, wet bulb temperature is maintained at 40 DEG C～43 DEG C to upper tobacco leaf, surely temperature 2～8 hours, until full a heatable brick bed
Nicotiana tabacum L. stops heating till all drying thoroughly or whole Nicotiana tabacum L. stops heating when being dried soon, is terminated using residual heat drying.
Extruded sheet heat-insulation layer is arranged on the inside on exterior wall, roof and ground.
Compared with the prior art, the present invention has advantages below：1st, baking Nicotiana tabacum L. first-class cigarette ratio out is high, variegated cigarette
Few, average price is high.2nd, baking time is short, and the time that the every a heatable brick bed cigarette of baking needs is 4 days～6 days.3rd, fuel, the exterior wall of tobacco flue-curing house are saved
The inside on body, roof and ground is all provided with extruded sheet heat-insulation layer, and the dry cigarette coal consumption often drying 1KG is 0.8KG～1KG.4th,
Save electricity, the wind speed design in tobacco flue-curing house cigarette-filling house is 0.12m/s, the power of each circulating fan be 0.3KW～
0.6KW, total head is 60Pa～80Pa, and the power consumption toasting every a heatable brick bed cigarette is 130 degree about.
