Description
Technical field
The present invention relates to the production method of tobacco industry reconstituted tobacoo, especially relate to a kind of method of tobacco sheet producing process using improved paper making.
Background technology
Reconstituted tobacoo (being also referred to as reconstituted tobacco) is to be primary raw material with the offal, the cigarette that produce in tobacco threshing and redrying and the production of cigarettes process broken (1～3mm tobacco leaf fragment), offal (the above broken ends of tobacco leaf of following 60 orders of 1mm), cigarette ash offals such as (the tobacco leaf powder that 60 orders are following), the regeneration tobacco leaf that processes from strand.It can become cigarette with natural tobacco leaf hybrid process.Produce, use the main purpose of thin slice to have two, one, can fully utilize raw tobacco material, reduce the wasting of resources; The 2nd, can effectively reduce tar content in cigarette and other harmful substance, stable roll smoke product quality.
Roll-in method, thick slurry method, paper process three phases have been experienced in the development of reconstituted tobacoo.Same roll-in method, thick slurry method thin slice are compared, and the paper process thin slice has clear superiority: the one, and density is little, filling value height; The 2nd, anti-machining property is good, becomes silk rate height; The 3rd, burning velocity is fast, and releasing content of coke tar is low, is one of effective means of cigarette lowering harm and decreasing coking; The 4th, product has plasticity, can carry out artificial regulatory to the physical property and the chemical index of thin slice according to the cigarette composition needs.
Domestic paper process preparation of sections is mainly adopted the two-step method production technology with producing, and promptly offal, cigarette broken (end) mix or immersion extraction respectively, and Separation of Solid and Liquid obtains extract and solid content then.Extract adds the various materials that production of cigarettes allows again through concentrating, and is deployed into the thin slice coating fluid.The solid content of offal, cigarette broken (end) obtains being fit to the slurry of paper machine making after the Separation of Solid and Liquid through technologies such as slurrying (mixing or mixed pulp after the slurrying respectively), and the adding certain proportion has been separated the plus fiber slurry of fine slurrying, obtain the thin slice substrate through paper machine making, press dewatering, drying, substrate is again through thin slice coating fluid dip coated, and the oven dry back breaks into sheet with flaker and promptly obtains paper process thin slice finished product.
Chinese patent ZL00117207.7, ZL93120477.1 and the disclosed method of Chinese patent application CN1324586A, CN1739411A and technology all are as the core of its patent working or basis with above-mentioned two-step process.The paper process slice production line that paper process slice production line that Guangdong gold leaf reconstituted tobacoo technological development Co., Ltd calendar year 2001 goes into operation and Hunan gold leaf reconstituted tobacoo Co., Ltd went into operation in 2004, also all with above-mentioned two-step process as core and basis.
Tobacco aroma when the paper process thin slice burns and sucks in the flue gas and smoke mainly come from the cigarette broken (end) in the slice raw material.Press two-step process production paper process thin slice, cigarette broken (end) at first will be through soaking extraction process.In the big production of reality, guarantee continuously uninterrupted production and the short as far as possible production cycle, this has just proposed many restrictions and requirement to extraction time, extraction water consumption, extraction equipment, solid-liquid separating equipment etc., thereby cause the extraction of cigarette broken (end) insufficient, quite a few still remains in the solid content after the Separation of Solid and Liquid fragrance and the contributive material of smoke, and the pulping process subsequently runs off because of being immersed in water for a long time.Simultaneously, cigarette broken (end) extract will be under higher temperature through the concentrating of long period, in this process, the many flavor matters in the extract can volatilize, decomposition, chemical combination, thereby cause the flavor matter further loss.Therefore, the paper process thin slice of producing by above-mentioned two-step process all exists tobacco aroma shortcoming, smoke deficiency, xylon gas and pungent sense qualitatively the sensory evaluating smoking and shortcoming such as gives prominence to.
Chinese patent application CN1739411A and CN1757334A disclose a kind of method that adds cigarette ash in producing tobacco flake in method similar to papermaking technology, and the certain operation that is chiefly directed to the two-step method production technology adds cigarette ash.This method can overcome the shortcoming that the thin slice cigarette is fragrant and smoke is short of that above-mentioned two-step process is produced to a certain extent, but also have weak point: the adding proportion of (1) cigarette ash is less, in web preparation with in producing, most cigarettes broken (end) still will be through soaking the enrichment process of extraction, slurrying and extract; (2) employed cigarette ash particle diameter (fineness) is bigger, and the adhesion strength when combining with thin slice slurry or substrate is less, and prepared thin slice finished product is easy to generate the dry linting phenomenon.
It is the method that raw material is made tobacco leaf paper with offal, offal that Chinese patent application CN1329855A discloses a kind of, its main technique is that offal is without soaking extraction process, offal slurry direct and behind immersion extraction, the defibrination mixes, and then mix with wood pulp or jute pulp, mix disposed slurry again behind the dilute with water, last paper machine making becomes tobacco leaf paper, and offal is extracted concentrate spray is added on the tobacco leaf paper.The weak point of this method mainly contains: (1) is at tobacco business, offal is often referred to the above broken end of tobacco leaf of following 60 orders of 1mm, but in beating and double roasting and production of cigarettes process, also produces the tobacco leaf fragment of 1 a large amount of～3mm, according to this method, these tobacco leaf fragments can't obtain utilizing; (2) even offal is broken at the conceptive cigarette that comprises 1～3mm in this method, but the experience of paper process and general knowledge show that the material of 1～3mm specification can not be gone up paper machine making; (3) the offal soak time is 12～14 hours in this method, will cause the whole production excessive cycle, can not adapt to continuously uninterrupted big requirement of producing; (4) in the method, offal at first mixes with offal slurry, and then mixes with wood pulp or jute pulp, adds reinforcing agent again and other paper making additive mixes, and just goes up paper machine making behind the dilute with water again.This process of being mixed will make offal long soaking time in water, and cause a large amount of strippings of tobacco DDGS, run off with mthod of white water from paper making.
