Description
Technical field
The invention belongs to stem processing technology field, be specifically related to a kind of medium-to-high grade cigarette stem processing method.
Background technology
Tobacco is Solanaceae Nicotiana plant, and stem is the thick and stiff vein of tobacco leaf, accounts for leaf and weighs 25% ~ 30%, can make an addition to after its chopping in cigarette.At medium-to-high grade tobacco productive corporation, (tobacco business divides five classes for cigarette, is to divide according to cigarette allocation and transfer price.Here medium-to-high grade cigarette refers to one, two class cigarette), due in stem containing being unfavorable for flue gas, inhaling taste and combustible cell wall substance, therefore its addition is few, fails to be fully used.As tobacco leaf production big country, the output of annual China tobacco leaf about 2,400,000 tons, can output offal about about 600,000 tons, the offal that wherein can be utilized effectively about about 400,000 tons, for processing the offal about 320,000 tons of stem, make the offal about 80,000 tons of reconstituted tobacoo, about have few hundred thousand tonnes of stem discarded object to be thrown aside waste.The cigarette of exploitation " high fragrance, low tar, less harmful " is the developing direction of China's cigarette product.Stem joins product as conventional mixing in cigarette product, has that fillibility is high, flammability good, in flue gas, produce the relatively low advantage of tar content, harmfulness, makes it for high-grade cigarette product, effectively can control harmful components and the releasing content of coke tar of cigarette.In offal, total reducing sugar, total nitrogen, nicotine and tar content are lower, cell wall substance content higher (about 43%), and offal fragrance when burning and sucking is not enough compared with tobacco leaf, inhales taste flat, excitant and strength less, assorted gas is heavier, and especially xylon gas is heavy.Meanwhile, due to color whitens after stem drying, mix with cut tobacco that to join rear color inharmonious, cigarette outward appearance after impact volume.Therefore, the defect that offal itself exists limits its adding proportion in medium-to-high grade cigarette.Along with the development of biotechnology, many researchers start to utilize enzyme and microorganism, change the sucking quality of of inferior quality tobacco leaf or improve the value of offal.
Prior art is in the majority directly to process stem, but due to Structure of Cut Stem fine and close, conventionally at present utilize the effect of enzyme preparation direct enzymolysis stem not remarkable.If the active principle in offal can be extracted, and suitably processes, remove solable matter in stem, reach the object to stem purifying.Then by reinforced backfill, supplement extract, improve stem aesthetic quality.So not only the product mass-energy of stem is improved, and stem can be made to obtain utilizing more fully.
Subcritical abstraction utilizes subcritical fluids as extractant, in airtight, anaerobic, in the pressure vessel of low pressure, according to the similar principle mixed of organic matter, by extraction material and the molecular diffusion process of extractant in immersion process, the dissolubility composition reached in solid material is transferred in liquid extractant, then by the process of reduction vaporization by extractant and object product separation, finally obtains a kind of novel extraction and the isolation technics of object product.Subcritical fluids refers to some compound in temperature higher than its boiling point but lower than critical-temperature, and pressure is lower than under the condition of its critical pressure, the material existed in liquid form.Be gas under mainly containing the normal temperature and pressures such as propane, butane, iso-butane, HFC-134a (R134a), dimethyl ether, sulfur hexafluoride, dicholorodifluoromethane (freon R12) and F-22 (freon R22), hold liquescent material through pressurization or cooling.
Summary of the invention
The object of the invention is to provide a kind of medium-to-high grade cigarette stem processing method.
Based on above-mentioned purpose, this invention takes following technical scheme:
A kind of medium-to-high grade cigarette stem processing method, packed under comprising the steps: the prerequisite of guarantee stem whole cut rate, entirety is placed in airtight extraction container, the extractant be in a liquid state with certain pressure is injected in container, by complete for stem submergence, extraction 30-50 minute, extraction temperature is 10-60 DEG C; Extractant is the mixture of one or more in propane, butane, iso-butane, HFC-134a, dimethyl ether, sulfur hexafluoride, dicholorodifluoromethane, F-22; After extraction terminates, in the process of desolvation, the temperature in extraction container remains on 10-60 DEG C, after lower vessel portion extracted liquid solvent, extract the solvent of gasification from the top of container out, after the solvent in stem removes completely, take out overall from container for stem bag; After stem extraction, feed in raw material to stem, feed ratio is 2.0-2.5wt%, after having fed in raw material, carries out expansion drying, perfuming, screening process, add in medium-to-high grade cigarette subsequently according to 3-5wt% ratio stem.The cigarette that the finished cigarettes tar content rolled and nicotine content in smoke do not add stem decreases, and is better than the cigarette not adding stem in perfume quantity, plentiful degree, flue gas fluency and strength etc.
After using method of the present invention to carry out purification process to stem, the face shaping of stem keeps good, reduces releasing content of coke tar in stem simultaneously, eliminates solable matter in stem.Then by reinforced backfill, supplement offal extract, improve stem aesthetic quality, the interpolation in high-grade cigarette formula can well be used for.
