Abstract
The production method of tobacco slice by using waste and low-grade tobacco as raw material includes the following steps: selecting raw material, cutting and adding extraction agent, soaking and extracting for 2-20 hr. at 50-80 deg.C, dewatering, separating, grinding to obtain pulp, pulping, storing pulp, then diluting pulp to 0.5-2%, feeding said material into paper-making machine to making slice paper base, after separating concentrating the soaking liquor cigarette-making auxiliary materials and added according to a certain proportion, then soaking the paper base in the soaking liquor, drying and cutting to obtain the invented tobacco slice.
Description
The invention belongs to tobacco comprehensive utilization and cigarette production field, be specifically related to a kind of pair of footwork full price and utilize the tobacco of various grades (especially discarded tobacco) raw material production to be used for the method for the reconstituted tobacoo of cigarette.
In the process engineering of producing cigarette, can produce a large amount of discarded tobacco-containing materials.These tobacco-containing materials bring great hidden danger not only for environmental protection and fire-fighting, and not being used simultaneously also is a kind of huge waste.This class substandard products tobacco still can utilize again in fact, turns waste into wealth.The scientific worker had once developed the method (as patent application 93120477.1 and 95103442.1) of abandoned tobacco with the explained hereafter cigarette of similar papermaking of utilizing.These class methods are with the tobacco making beating basically, copy into the scraps of paper, simultaneously in pulping process with under the dissolving of compositions such as nicotine, tar, the nicotine that extracts is applied on the scraps of paper again, and operation is made cigarette to add assistant agent, chopping such as essence at last by the traditional handicraft of cigarette, roll etc.The cigarette that this method rolls is substantially free of tar, therefore can be referred to as nontoxic cigarette.The advantage of this method is the full price utilization of tobacco.But owing to also have many defectives in the arrangement of process conditions control and process, make technology cost height, economic benefit is relatively poor, the inventor has developed a kind of more easy, discarded method that reaches low inferior tobacco material production reconstituted tobacoo of full price utilization efficiently through concentrating on studies for this reason.
The object of the present invention is to provide a kind of reaching with the scrap feed material in the tobacco production process to hang down inferior tobacco leaf, the method for reconstituted tobacoo is produced in the full price utilization.
Fig. 1 is a process chart of the present invention.
Concrete operation is followed successively by:
Raw material is removed impurity such as metal, plastics through selection, rough lumber is to 5-20mm, again by the liquid material than 5-6: 1 ratio adds extractant and soaks extraction down after 2-20 hour at 50-80 ℃, and dehydration separates, and its moisture content is controlled 70-80%; Carry out defibrination then, grinding clearance is 0.2-0.5mm, pulls an oar after can adding the wood pulp of 2-8%, and beating consistency is controlled at 8-12%, and beating degree is 30-40 ° of SR.Slurry is sent into slurry can, storage slurry concentration is about 3%, send into again and dash the slurry case, dash slurry concentration and be controlled at 0.5-2%, enter paper machine (drying nest adopts drying cylinder and tunnel type heated-air drying technology) then and copy flakiness paper substrate made of paper, the paper substrate grammes per square metre is 80 ± 3g/m2, and thickness is 0.18 ± 0.02mm, moisture 30%.Soak is after composition separates, at 60-80 ℃, 0.04-0.06MPa negative pressure under concentrate concentration to 30-40%, in concentrate, add additives such as combustion adjuvant, humectant, the fragrant reinforcing agent of cigarette, with sheet paper base dip-coating in concentrate, microwave drying process oven dry, branch cut into tobacco product grass thin slice.
For tobacco stalk raw material, the defibrination operation can be considered defibrination twice, and a grinding clearance is 0.5mm; The secondary grinding clearance is 0.2mm.For the tobacco leaf fragment raw material, one time defibrination gets final product, and grinding clearance is controlled at 0.2mm.
Raw material carries out rough lumber to 5-20mm, cooperates extractant water or ethanolic solution to extract, and helps to greatest extent the solable matter in the tobacco to be extracted.Under the normal pressure heating condition, extract and help softening, discongesting of paper-making fibre.
The sheet paper base oven dry adopts drying cylinder to add tunnel type heated-air drying technology, and the finished product thin slice adopts the microwave drying process oven dry.
Concentrate only adopts the extract of tobacco leaf class raw material, and adopt low pressure to concentrate, temperature when concentrating with dip-coating is controlled at 60-80 ℃, and its purpose is to reduce xylon gas and the excitant of reconstituted tobacoo when suction, and guarantees that the effective flavor matter of tobacco in the concentrate is fully appeared.
The present invention's technology makes the releasing content of coke tar of tobacco be lower than natural tobacco leaf, has reduced the tar content in the cigarette.Not only technological process is simplified, and the sheet product density that makes is little, and gas permeability and machining property are good, are convenient to long preservation, and helps to improve the inherent quality and the quality of cigarette products.Improving the economic worth of low-grade tobacco leaf simultaneously, is a kind of tobacco material of both having saved, and can lower the excellent production process technology of cigarette tar content again.
The present invention is further illustrated below in conjunction with embodiment, but never in any form the present invention is limited.
