Abstract

With the offal in the production of cigarettes, add composite adhesive etc. and make reconstituted tobacoo with roll-in method, realize that discarded offal utilizes again.The invention reside in the use sodium carboxymethylcellulose, take off the acetylglucosamine polymer and form composite adhesive, the reconstituted tobacoo of production meets reconstituted tobacoo standard (draft).Intensity and water resistance all are improved largely and improve, and cost is low, and offal utilization rate height is good in economic efficiency.

Description

Reconstituted tobacoo composite adhesive and production technology

The invention belongs to the reconstituted tobacoo production technology.

Will produce the offal less than 3mm of 3-8% in the production of cigarettes process, what abandon is useless, contaminated environment.These offals are processed into reconstituted tobacoo (tobacco leaf of promptly regenerating), return production technology, make cigarette at last, can improve the tobacco leaf utilization rate, obtain economic benefit; Can turn harm into good again, the protection environment, during reconstituted tobacoo was produced, adhesive and technical process all were crucial.

The production of reconstituted tobacoo at present mainly contains roll-in method, thick slurry method and paper process.Roll-in method is earlier that levigate offal and dry adhesive powder is mixed, and water furnishing pasty state is rolled into thin slice and oven dry then, and demoulding is cut into the shape of requirement then.What also have by a certain percentage behind the mixing, is rolled into film, oven dry with the reconstituted tobacoo machine with offal and carboxymethyl cellulose, glycerine, phosphoric acid, water, scrapes the shape that is cut into requirement with perching knife.The humectant of thin slice is except that with the glycerine, also available maltose, sorbierite etc.Thick slurry method is that the silt on crumbled tobacco and the offal is washed off, clayed into power after the drying, powder is added in the solution that contains adhesive, combustion adjuvant, mineral matter ash content, humectant and fortifying fibre, the thick slurry of furnishing, thick slurry be coated in film forming on the stainless steel band, drying, moisture regain, demoulding, spool or be cut into square.Adhesive therefor has: carboxymethyl cellulose, methylcellulose, guanidine beans or locust bean gum etc.; Fortifying fibre is used wood pulp cellulose always; Humectant glycerine, ethylene glycol etc.Paper process is to handle tobacco chippings with heat alkali liquid in closed container, extract wherein water-soluble substances, prevent the volatile substance effusion simultaneously, leach residue, use the caustic soda boiling adding to depress, obtain slurry and pull an oar, make filamentization and reduce fibre length through beater, on the paper machine screen cloth, form the slurry layer then, use the hot-air drying; Meanwhile, the tobacco extraction liquid that leaches adds humectant and combustion adjuvant through concentrating, and on its impregnation of fibers paper web, drying, gets damp again, spools or be cut into square.What present domestic application was more is roll-in method.

The reconstituted tobacoo that said method is produced, the water imbibition and the tensile strength of product are lower, so have considerable part to become offal again when returning production technology processing cigarette, economic benefit is low.

The objective of the invention is to provide a kind of component prescription of new reconstituted tobacoo and improve production technology, improve the water resistance and the tensile strength of reconstituted tobacoo, save original humectant and combustion adjuvant, improve offal utilization rate, increase economic benefit.The object of the present invention is achieved like this: after levigate offal and wood pulp cellulose, carboxymethylcellulose sodium solution are prepared burden according to a certain percentage, stir, on the reconstituted tobacoo roll squeezer, be rolled into film, after spraying then and take off acetyl-glucosamine polymer solution curing, drying, scrape the shape that is cut into requirement with perching knife, its concrete ins and outs and production technology are:

Raw material proportioning: offal and offal 82-89%

Wood pulp cellulose 5-10%

Sodium carboxymethylcellulose 3-5%

Take off acetylglucosamine polymer 3-5%

Foreign material sortings such as the dust in offal, the offal, silt, metal are removed offal, offal, sodium carboxymethylcellulose is mixed by proportioning, pulverizing, levigate to 80 orders (or 80 order to 100 orders).The wood pulp cellulose of adding through discongesting, the drying cake that wets adds water, and mixed stirring send roll squeezer to be rolled into thin slice, be sprayed at equably on the thin slice with taking off the polymeric solution of acetylglucosamine, oven dry, cooling, chopping product.

Wherein wood pulp cellulose can replace with the cellulose that the cigarette paper that filters out in the waste product of cigarette workshop is made through the beater making beating, and is better by the reconstituted tobacoo performance that above-mentioned prescription is produced.

The used composite adhesive raw material of the present invention: the poly system of taking off acetylglucosamine is extracted from marine animal, have nontoxic, tasteless, moistureproof, prevent the characteristics of going mouldy.Another raw material, sodium carboxymethylcellulose are the common food additive, and the composite adhesive that both form can form one deck reticulate body.And domestic other like product does not all have this structure on the electron microscope photo scanning.Just because of adopted novel adhesive and novel production technology, make every performance of its product all reach reconstituted tobacoo standard (draft); Particularly the tensile strength of thin slice is 2～4 times of draft standard.It also has good water imbibition, thereby makes the utilization rate of offal bring up to (at present domestic each tobacco plant slice production, the utilization rate of offal is 60-70%) more than 85%.Compared with prior art, new technology has been save additives such as humectant.

Realize that best way of the present invention is to add a sprayer unit in the flow process of roll-in method production reconstituted tobacoo, before wet reconstituted tobacoo enters dryer, the polymer solution that takes off acetylglucosamine on spraying equably is cured, and can obtain good reconstituted tobacoo.

Claims

1, a kind of composite adhesive of producing reconstituted tobacoo, it is characterized in that forming by sodium carboxymethylcellulose and the polymer that takes off acetylglucosamine, its proportioning is: (accounting for the percentage of raw material) sodium carboxymethylcellulose 3-5%, take off the polymer 3-5% of acetylglucosamine.

2, the reconstituted tobacoo of proportioning production according to claim 1 is characterized in that spraying on wet thin slice and takes off acetyl-glucosamine polymer solution, makes the thin slice film-forming.
