Description
Technical field
The present invention relates to tobacco threshing and redrying processing technique field, particularly the continuous beating and double roasting processing technology of a kind of modified tobacco leaf.
Background technology
Beating and double roasting is a kind of technology of carrying out processing process to former cigarette, is the processing processing procedure these agricultural product of tobacco leaf being changed into the raw material of industry.Reduce tobacco leaf broken rate by the processing of beating and double roasting, thus provide normalized raw material to cigarette factory, to ensure tobacco quality.Before beating and double roasting, first will carry out pretreatment to tobacco leaf, the tobacco leaf being about to be bundled into handle makes it to scatter after untiing, and is humidified to it, adds wet process, to meet leaf beating process requirement.
In recent years, although there is very people's progress in beating and double roasting enterprise and improves in the physical qualities such as solution piece rate, moisture, smoked sheet offal structure, but new, the higher requirement that current brand development proposes raw material preparatory processing can't be adapted to, often there is beating and double roasting and throwing link discrepancy, beating and double roasting rear panel cigarette unreasonable structure, cause tobacco structure unreasonable, cause density of tobacco rod uniformity and end tobacco-falling index to be difficult to the problems such as control.Can say, beating and double roasting has become the weak link of current characteristic technology research, is Cigarette Industrial Enterprise urgent problem to the strict control of tobacco strip structure quality.
The development one of raw material of cigarette is that will to solve tobacco leaf gross qualified and stable, two is the aroma qualities that will improve tobacco leaf, can three be to form rich and varied provincialism and characteristic, therefore in process, carry out maximum possible reservation to this perfume (or spice) of tobacco, and sheet cigarette redrying link is particularly crucial.Now domestic redrying industry cooked mode utilizes high temperature the flex point moisture content 8-10% of drying tobacco to tobacco leaf, then after the cooling of cooling zone, the upper tide of moisture is carried out in moisture regain district, thus reach vanning requirement, in this process tobacco leaf due to baking temperature too high, cause a large amount of losses of the tobacco leaf banksia rose, reduce the comprehensive use value of tobacco leaf, thus we will explore a kind of newly strong redrying technology.
Wind dispensing is the important step in tobacco threshing and redrying process, and wind dispensing quality directly affects the important production targets such as the unit pipe tobacco consumption of final production of cigarettes, and the quality such as cigarette smoking taste.In wind dispensing process, its quality control index comprises: containing leaf rate etc. in piece rate, Percentage of large and middle size strips, small pieces rate, fragment rate, Ye Zhonghan stalk rate, long stalk rate, short stalk rate and stalk.Wherein: piece rate is the important indicator embodying tobacco leaf utilization rate, also be the important indicator guaranteeing tobacco threshing and redrying productivity effect: Percentage of large and middle size strips is directly connected to the effect of tobacco leaf chopping, improve Percentage of large and middle size strips and have very important impact to improving pipe tobacco formation, and the further improvement that pipe tobacco is formed, the utilization rate of pipe tobacco can be significantly improved, thus reduce the consumption of tobacco leaf pipe tobacco.In traditional wind dispensing technique, improve Percentage of large and middle size strips and must reduce small pieces rate and fragment rate, also can increase containing stalk rate in leaf, this is a pair very scabrous contradiction simultaneously.Ye Zhonghan stalk rate is directly connected to stalk in scrap prodn. line and signs and obstruct the quantity of block, stalk is signed and is obstructed the filling power that number of blocks increase can reduce pipe tobacco, both be unfavorable for that cigarette was burnt, harmful effect can be produced again to suction taste, in the process simultaneously rolled in cigarette, stalk is signed and stalk block can puncture cigarette paper, or causes cigarette machine to run bar, have impact on the service efficiency of cigarette machine, cause pipe tobacco to waste.And desirable leaf quality index of beating is: higher piece rate, Percentage of large and middle size strips and long stalk rate, and keep in very low Ye Zhonghan stalk rate and stalk containing leaf rate.
Soft to play segmentation be a kind of new technology occurred in recent years, beating roller rotating speed, reducing the load on dozen roller unit width by reducing, and by multistage combining form of making leaf, multistage wind score, reduce and beat roller load, improve wind component efficiency, thus reduction is made broken, improve Percentage of large and middle size strips.But soft segmentation technique of beating does not change traditional wind dispensing pattern, but also prisoner increases threshing machine group, and blade and stalk are torn repeatedly; Divide device because increasing wind again, and cause the increase of broken rate and energy consumption.Therefore, must improve existing wind dispensing technique.
Based on above analysis, design a kind of scientific and reasonable tobacco threshing and redrying processing technology, promote beating and double roasting quality, keep the original fragrance of tobacco leaf, reduce production cost, improve quality of tobacco and seem particularly important.
Summary of the invention
