Abstract
The present invention discloses a cut tobacco -drying technics during processing cigarette, which comprises two steps: the first step is to balance the water content of cut tobacco to 20 percent, and the cut tobacco is guided into a pneumatic drier, wherein the technics air temperature in the first section of pneumatic drier is controlled between 80 and 100 DEG C, and that in the second section is controlled between 70 and 90 DEG C, then the cut tobacco with 20 percent water content is dried and the water content is lowered to about 14 to 16 percent; and the second step is that the dried cut tobacco is guided into a roller dry machine for the secondary drying procedure, wherein the temperature of the wall of the roller is controlled between 70 and 80 DEG C, to control the water content of the dried cut tobacco between 12.0 percent and 13.0 percent. The present invention can not only improve both the uniformity of the water content and temperature stability of the processed tobacco with increased filling capability of the dried tobacco, but also reduce the loss of the fragrance of tobacco, to significantly decrease the content of injurious ingredients contained in cigarette such as tar, smoke and nicotine.
Description
Technical field
The present invention relates to the drying process of material, especially the leaves and tobacco drying method in the cigarette process.
Background technology
Drying is a most important production link in the cigarette process, and its basic task is the part moisture that will remove exactly in the tobacco, improves its filling capacity and anti-processability, improves the suction flavor of tobacco simultaneously, reduces excitant and assorted gas.
The drying means of tobacco mainly contains two kinds, and a kind of is the convection type drying means, by convection heat transfer' heat-transfer by convection between high temperature gas flow and leaf (stalk) silk, realizes the purpose of drying.Another kind is the conduction-type drying means, and the conduction at a slow speed by cylinder barrel and leaf silk reaches the crudy requirement.No matter be air-flow drying method, or drum drying method, its process gas treatment temperature must be greater than 130 ℃, and just can make the supplied materials moisture content is that 20%～28% leaf silk is dried to about 12.5%, to satisfy the postorder processing request.
In traditional process, be confined to improve the leaf silk and partly inhale flavor by adjustment equipment working process parameter.And a large amount of experiments shows, for medium-to-high grade high-quality leaf silk, when the process gas treatment temperature is higher than 100 ℃, the obvious variation of dry posterior lobe silk fragrance matter meeting, perfume quantity also significantly reduces, obviously only can't satisfy lower processing requirement of strength, can't satisfy leaf silk moisture simultaneously and inhale the quality requirement of distinguishing the flavor of by the technological parameter of adjusting in the existing drying means.On the other hand, no matter be the convection type drying mode, or the roller drying mode, all can't solve the fluctuation that reduces moisture content, temperature simultaneously and improve conspicuous contradiction between leaf silk filling capacity.Specifically, air-flow drying method adopts the process gas flow more than 130 ℃ to handle, though can significantly improve the filling capacity of leaf silk, the fluctuation of handling back moisture content of cut tobacco and temperature is bigger, and uniformity is relatively poor; Drum drying method mainly comes drying leaf-silk by the barrel temperature more than 140 ℃, though can reduce to export the fluctuation of moisture content of cut tobacco and temperature, can't reach filling capacity preferably.
Summary of the invention
Deficiency at the prior art existence, the object of the present invention is to provide and a kind ofly can improve the uniformity of handling posterior lobe silk moisture and the stability of temperature, significantly increase dry posterior lobe silk filling capacity, can reduce the loss of perfume quantity and fragrance matter again, make the leaves and tobacco drying method in the cigarette process that the harmful components such as tar content, nicotine content in smoke of cigarette obviously reduce.
The present invention solves the technical scheme that its technical problem takes: the leaf silk drying process in a kind of cigarette process, it is made up of two steps, the first step will be cut posterior lobe silk balancing water content to 20%, import in the pneumatic drier, pneumatic drier Zhong Yi district process gas temperature is controlled at 80～100 ℃, two district's process gas temperature are controlled at 70～90 ℃, are that 20% leaf silk is dried to about 14～16% with moisture content; Second step was sent into dried leaf silk and carries out the drying processing in the roller drier once more, and the barrel temperature is controlled at 70～80 ℃, made dry back moisture content of cut tobacco at 12.0-13.0%.
Leaf silk drying process in the described cigarette process, in the pneumatic drier of the first step, one district's gas flow temperature control range is 80～90 ℃, two district's gas flow temperature control ranges are 70～80 ℃, dry back moisture content of cut tobacco is 16%, in the roller drier in second step, the barrel temperature is 80 ℃.
Leaf silk drying process in the described cigarette process, in the pneumatic drier of the first step, district's gas flow temperature control range is 85～95 ℃; Two district's gas flow temperature control ranges are 75～85 ℃, and dry back moisture content of cut tobacco is 15%, and in the roller drier in second step, the barrel temperature is set to 75 ℃.
Leaf silk drying process in the described cigarette process, in the pneumatic drier of the first step, district's gas flow temperature control range is 90～100 ℃; Two district's gas flow temperature control ranges are 80～90 ℃, and dry back moisture content of cut tobacco is 14%, and in the roller drier in second step, the barrel temperature is set to 70 ℃.
Cigarette processing method of the present invention, carry out pneumatic conveying drying by the pipe tobacco after will cutting earlier, purpose is to improve the filling capacity of leaf silk, dispel assorted gas, reduce excitant, and then dried leaf silk importing roller drier is carried out once more drying handle, improve the uniformity of outlet moisture content of cut tobacco and the stability of temperature, the process gas treatment temperature of whole dry run is not higher than 100 ℃, keep leaf silk fragrance to greatest extent, reduce the fluctuation of processing posterior lobe silk moisture and temperature, significantly increase dried filling capacity, reduce the loss of leaf silk perfume quantity, make the tar content of cigarette, harmful components such as nicotine content in smoke obviously reduce.
