Abstract
The invention relates to a method for expanding cut tobacco stems. An existing technology for expanding the cut tobacco stems has the problems of high breakage rate and complex process. In order to overcome the problems in the prior art, the technical scheme adopted by the invention is as follows: tobacco stems after leaf threshing are taken as raw materials for producing the expanded cut tobacco stems, and the process flow comprises the following steps of: obtaining the tobacco stems after leaf threshing, removing impurities and broken stems, performing humidification, performing pressure-difference expansion, performing moisture regain, cutting, performing far-infrared vacuum drying and obtaining the expanded cut tobacco stems. The method disclosed by the invention adopts the process of firstly expanding and then cutting and is combined with a far-infrared compound heating and pressure-difference expansion combined technology, so that the defects of high breakage rate, residue of an organic expanding medium and high energy consumption of the existing technology for expanding the cut tobacco stems are overcome, and the method has the characteristics of safety, high efficiency and wide applicability.
Description
technical field:
The invention belongs to tobacco manufacture field, relate to a kind of method of expanded offal silk.
background technology:
In prior art for the production of the raw material of cigarette except a large amount of Tobacco Leaves, beat exactly remaining offal after leaf.Good expanded stem can not only increase the filling value of pipe tobacco, reduces tarry matters in smoke content, and can ensure the stable of taste, increases selling point, is one of important component part of cigarette shreds.
At present, the sequencing of and chopping expanded according to offal, can be divided into the bulking process of offal two large classes.The first kind is " first cutting rear swollen ", as Chinese patent application 200710054068.8, Chinese patent application 200710053001.2 etc." first cut " technique rear swollen because offal throwing is front, easily produce more stalk label, stalk end, reduced the utilization rate of offal.Equations of The Second Kind is " after first swollen, cutting ", as Chinese patent application 01108471.5, Chinese patent application 200310112837.7 and Chinese patent application 200510118934.6 etc." first swollen then cut " technique is mainly the deficiency that overcomes " first cutting rear swollen " technique by changing chopping and expanded order.Wherein, Chinese patent application 01108471.5 and Chinese patent application 200310112837.7 be all taking the swollen stalk technology of microwave as core, has the low and simple advantage of technique of energy consumption, but it is expanded to be generally only applicable to the offal of low water content.It is 200 DEG C～350 DEG C that offal is exposed to temperature by Chinese patent application 200510118934.6, in the superheated steam that pressure is 10bar～20bar, after 10s～20s, makes the mixture of steam and offal realize the expanded of offal by nozzle aperture rapidly.It is expanded that this technology adopts superheated steam to heat, and can significantly overcome organic expanded medium residue problem, but the efficiency of " recovering sizing " is low, energy consumption is high.Therefore, the pluses and minuses of comprehensive above two large class offal puffing techniques, offal silk bulking process residual, energy-efficient without organic expanded medium and wide adaptability is the development trend of offal processing.And " cutting after first swollen " method of far infrared composite heating pressure-difference and puffing offal silk just in time suits requirement in this respect.
summary of the invention:
The offal silk process technology that the invention provides a kind of residual without organic expanded medium, efficient and wide adaptability " cutting after first swollen ", has solved the problem of making broken height, complex process in existing offal silk puffing technique.
The technical solution used in the present invention is: far infrared composite heating and pressure-difference and puffing United Technologies processing cigarette stem, comprise the steps:
Pretreatment of raw material: tobacco prophyll is played offal removal of impurities, the dedusting after leaf, rejects the broken stalk that is less than 5mm.
Add wet process: the offal after pretreatment is sprayed water and added wet process, control its moisture stand-by between 30%～40%.
Pressure-difference and puffing: first Bulking tank temperature is risen to 90 DEG C～110 DEG C, open Bulking tank, tobacco stalk raw material after treatment humidification is positioned in Bulking tank, maintain the temperature at 90 DEG C～100 DEG C, Bulking tank internal pressure is risen to 0.26MPa～0.3MPa simultaneously, and keep 15min, and now the swelling temperature of tobacco stalk raw material is 82 DEG C～85 DEG C, bulking pressure is 0.22MPa～0.28MPa; Then moment is opened the magnetic valve that connects Bulking tank and vacuum tank, makes the vacuum state of two tanks after balance and keeps 10min～35min, cools the temperature to 70 DEG C～75 DEG C dry 20min～40min; Finally be water-cooled to 35 DEG C～45 DEG C by the circulating cooling of 20 DEG C～25 DEG C, obtain expanded offal.
Moisture regain: to the offal spraying steam moisture regain after expanded, control its moisture 16%～18%.
Cut open silk: the offal after moisture regain cuts open silk on wire dissecting machine, obtains stem.
Stem is placed in to far infrared vacuum drying tank and is dried, make stem return to faster expanded state, stem final moisture content is controlled at 12%～14%, obtains expanded offal silk.
The above-mentioned offal silk cuing open after silk is dried in far infrared vacuum drying tank, and in tank, vacuum is 0.084MPa, and temperature is 70 DEG C～78 DEG C, and be 20min～30min drying time.
The present invention is with respect to prior art, and tool has the following advantages and effect:
1. adopt the technique of " cutting after first swollen ", can reduce the broken rate of offal silk.
2. in expanded, using " water " without potential safety hazard as the expanded medium of offal, overcome the shortcoming that loss is large, expense is high that adopts carbon dioxide puffing technique, also can not bring the residual problem of organic media simultaneously.
3. the method for " external pressurized " makes bulking process adaptability wider.
4. after cuing open silk, adopt far infrared vacuum drying to recover sizing, can effectively reduce energy consumption, raise the efficiency.
