Abstract
The invention provides a flash evaporation puffing and roller drying treatment process for stalk shreds. According to the treatment process, jet type stalk shred heating and humidifying equipment and steam-heated drum-type shred baking equipment are adopted, the filling value of the stalk shreds is increased from 5.6 cm<3>/g to 6.0 cm<3>/g, namely increased by 7.1%, the processing resistance of the stalk shreds is markedly increased, the stalk shred output rate is increased by 0.6%, the integral stalk shred rate is increased by 1.4%, the outlet water content of the dried stalk shreds is uniform, the water content fluctuation is controlled within a range of +/-0.4%, the woody gas influence caused by stalk shreds in the cigarette product is effectively avoided, and at the same time, the dried stalk shreds are better in water content uniformity and lower in water content fluctuation.
Description
Technical field
The invention belongs to cigarette producing process technology, especially a kind of stem flash evaporation puffing and roller drying treatment process.
Background technology
At present, stem explosion puffing drying mainly contains following mode, and first kind of way is stem HT+ stem cylinder (or fluid bed) drying mode; The second way is stem flash evaporation puffing+stem fluidized bed drying mode.First kind of way is conventional stem processing mode, and processing technology is ripe, be widely used, and comparatively speaking, HT section is limited to stem expansion effect for this mode, is removing xylon gas, and improving stem filling capacity aspect has larger limitation.The second way is new technology pattern, compare with first kind of way, on the basis of first kind of way, the physical performance index of stem (as filling value, Structure of Cut Stem) and the performance in cigarette product (the bad breath such as xylon gas) obviously improve, successful.Stem physical performance index successful after the second way is processed, but after dry, the water uniformity of stem is poor, moisture fluctuation is larger.
Summary of the invention
The object of the invention is to propose a kind of improved stem flash evaporation puffing and roller drying treatment process, adopt stem flash distillation to dry with drum-type the stem explosion puffing drying mode that stalk machine is connected, effectively overcome the deficiency that above-mentioned prior art exists, can improve the physical performance index of stem, again effectively remove bad breath that in cigarette product, stem brings, simultaneously dry after stem water uniformity better, the less good result of moisture fluctuation.
Technical problem to be solved by this invention is achieved through the following technical solutions: a kind of stem flash evaporation puffing and roller drying treatment process, and adopted injecting type stem heating and moistening equipment and steam-heated drum-type to dry silk equipment, it is characterized in that having the following steps:
(1) injecting type stem heating and moistening: stem falls into charging gas lock by feed hopper, send into expanding chamber, saturated vapor is delivered to stem rapidly the throat of expansion tube simultaneously, and the stem after expansion is through whirlwind and gas lock blanking, steam is separated and discharged simultaneously, in said process, stem flash vaporization inlet stem moisture content 35～38%, moisture content increases by 1～2%, feeding temperature 20-30 ℃, working steam pressure 0.35-0.6Mpa, 60～80 ℃ of drop temperatures, the working time is about 5 seconds;
(2) steam-heated drum-type is dried silk: pipe tobacco is sent into front chamber inlet by vibration conveying equipment, the pipe tobacco simultaneously hot blast that stir-fries passes from drying cylinder, hot blast is blown over along the direction of pipe tobacco motion in drying cylinder, in said process, supplied materials moisture content: 36～39%, supplied materials temperature: 60～80 ℃, discharging moisture content: 13%, 100～140 ℃ of working heat air temperatures, steam pressure: 0.4～0.8Mpa, barrel diameter: 1440mm, drum length: 8000mm, drum-inclined angle: 0.5 °, the working time is about 5 minutes.
The present invention adopts stem flash distillation to add after the treatment process of roller drying, the 5.6cm after stem filling value is processed by original stem HT+ roller drying mode
3/ g brings up to stem flash distillation and adds the 6.0cm after roller drying mode is processed
3/ g, has improved 7.1%, and the resistance to processing characteristics of stem obviously increases, go out stem rate and improved 0.6%, stem whole cut rate has improved 1.4%, and the moisture content of outlet of dry rear stem is even, moisture fluctuation is controlled at ± 0.4% scope in, effectively removed the impact of the xylon gas that in cigarette product, stem brings.Can adopt suitable raising to cut width of peduncle thread and stem flash distillation and add roller drying mode and combine utilization, obtain significant stem processing effect.Cylinder dries stalk machine Length Ratio fluidized bed type and dries the short 2.6m of stalk machine, and equipment investment volume approaches, so this technological equipment investment is few, and floor space is little.Can process stem and obtain good physical performance index numerical value, effectively reduce the bad performance that in cigarette product, stem brings: as bad breaths such as xylon gas etc., the water uniformity of dry rear stem is better simultaneously, moisture fluctuation is less, to the steady quality of whole cigarette product, provides good guarantee.
The specific embodiment
Below the specific embodiment of the present invention is elaborated.
(1) stem flash evaporation puffing adopts injecting type stem heating and moistening equipment, its principle is by feed hopper, to fall into charging gas lock when stem, send into expanding chamber, saturated vapor is delivered to stem rapidly the throat of expansion tube simultaneously, and heat exchange at a high speed impels stem humidity and temperature to increase, and is subject to the effect of high temperature and low pressure in throat, moisture in stem cell is evaporated rapidly, impel wood fibre highly porous, the instantaneous expansion of volume, thus reach expansion object.Stem after expansion is through whirlwind and gas lock blanking, and steam is separated and discharged simultaneously.In process of production, stem flash vaporization inlet stem moisture content 35～38%, moisture content increases by 1～2%, feeding temperature 20-30 ℃, working steam pressure 0.35-0.6Mpa, 60～80 ℃ of drop temperatures, the working time is about 5 seconds.
(2) the steam-heated drum-type cut-tobacco drier of the dry employing of stem, impel pipe tobacco evenly to dry, heat and the raising of filling value, pipe tobacco is sent into front chamber inlet by vibration conveying equipment, and the rotatablely moving of drying cylinder adds that its inclination angle can guarantee constantly and heat exchanger plate Surface Contact pipe tobacco.Pipe tobacco stir-fries and while hot blast passes from drying cylinder, and pipe tobacco can be dried and heat more equably, and hot blast is blown over along the direction of pipe tobacco motion in drying cylinder, takes away the moisture in pipe tobacco.In process of production, supplied materials moisture content: 36～39%, supplied materials temperature: 60～80 ℃, discharging moisture content: 13%, 100～140 ℃ of working heat air temperatures, steam pressure: 0.4Mpa, maximum 0.8Mpa, barrel diameter: 1440mm, drum length: 8000mm, drum-inclined angle: 0.5 °, the working time is about 5 minutes.
