Abstract

A method for testing tobacco flakes mixing ratio of cut tobacco blend is characterized in that the method comprises the following steps: a. preparing solvent; b. placing cigarettes in the environment which has certain temperature and humidity to balance, taking out the cigarettes, then taking out the cut tobacco in the cigarettes, weighting, recording the weight as W; c. putting the cut tobaccos in a container, adding the prepared solvent, stirring, standing for 1-3min, taking out the cut tobaccos floating on the liquid, drying, weighting and recording the weight as P; d. the tobacco flakes mixing ratio Y of the cigarettes is calculated by the following formula: Y is equal to (W-P)/W*100%. The invention provides a relatively intact and feasible method for testing tobacco flakes mixing ratio of cut tobacco blend fast and accurately, can provide reliable technical parameters for controlling tobacco flakes mixing ratio of cut tobacco blend, thus being significant for controlling the quality index of cigarettes and promoting the physical quality of Chinese tobacco products and the inner quality of the products as a whole.

Description

Sheet and shreds was mixed the method for ratio during a kind of mensuration cut filler

Technical field

The present invention relates to a kind of mensuration cut filler in sheet and shreds mix the method for ratio, relate in particular to a kind of method that sheet and shreds during sheet and shreds and mensuration cut filler in the cigarette composition pipe tobacco is mixed ratio of separating.

Background technology

Improving constantly along with human civilization advance and living standard in recent years, smoking is day by day appeared suddenly with healthy contradiction, people pay close attention to further to the security of cigarette product, and thin section for tobacco is used by domestic and international many cigarette enterprises as a kind of production technology of maturation.It improves tobacco structure and filling capacity for reducing tar content in cigarette and tobacco leaf consumption, improves the tobacco leaf effective rate of utilization and has vital role.

At present, domestic cigarette enterprise adopts tobacco sheets by paper making method and rolling process reconstituted tobacco as the batching pipe tobacco and roll into cigarette and prop up usually, it can reduce tobacco leaf consumption, make full use of the tobacco leaf resource, simultaneously along with the progressively raising of sheet and shreds ratio in cutting filler, the individual cigarette weight of Cigarette, burn and suck a mouthful number, T/N amount etc. and all can progressively descend.But mix a certain proportion of sheet and shreds in cutting filler after, smoke components can change, and is bigger to aesthetic quality's influence of cigarette.Therefore, the ratio of mixing sheet and shreds during control cuts filler has great importance for the quality of controlling cigarette.Applicant of the present invention had once applied for a Chinese patent, its application number is 200610018085.8, denomination of invention is selected leafing silk, expanded cut stem, papermaking sheet and shreds, roll-in sheet and shreds, unexpansive stem, the ratio of mixing of the various leaf silks of corresponding again calculating, stem, sheet and shreds etc. for " a kind of method of measuring tobacco shred ratio in cigarette " is by hand by the different external appearance characteristics according to various pipe tobaccos and sheet and shreds below magnifier.This method hand picking, process is numerous and diverse, efficient is low, workload is big, but so the insider wish to find a kind of very simple and convenient also fast measuring cut filler in sheet and shreds mix the method for ratio.

Summary of the invention

Sheet and shreds was mixed the method for ratio during a kind of mensuration that purpose of the present invention provides specially at existing problem in the above-mentioned prior art just cut filler.

Purpose of the present invention can realize by following technique measures: method of the present invention may further comprise the steps:

A, allotment solvent;

B, cigarette propped up to put into temperature be 20 ± 2 ℃, humidity is balance 24 ± 2 hours in 65% ± 5% the environment, take out cigarette then and prop up, and pipe tobacco took out during cigarette propped up, and the record of weighing, and be designated as W;

C, pipe tobacco is put into container, add deployed solvent, left standstill after the stirring 1～3 minute, take out the leaf silk that swims on the liquid level, oven dry, the record of weighing, and be designated as P;

The ratio of the mixing Y of sheet and shreds calculated as follows during d, cigarette propped up:

Y＝(W-P)/W*100％，

In the formula: Y: be the mixing ratio of mixing of sheet and shreds

P: be floating posterior lobe silk net weight

W: be pipe tobacco net weight before floating.

In the present invention, described solvent is to be mixed to join by second alcohol and water 1: 1 by volume～5 to form, and is preferably 1: 3.Why selecting ethanol for use, is because it is nontoxic, volatile during oven dry, noresidue etc., and ethanol also can be substituted by water-soluble, volatile organic solvents such as methyl alcohol, propyl alcohol.

Drying course of the present invention is the leaf silk to be put into baking oven carry out under 90～110 ℃ condition.

The present invention adopts the floating mode of solvent to carry out the principle that sheet and shreds separates in the cigarette composition pipe tobacco: various leaf silks (comprising expansive cut tobacco), stem (comprising expanded cut stem) are because water absorptivity is relatively poor in cutting filler, reasons such as density is less, all can be floating, sheet and shreds is because water absorptivity is stronger, cause sheet and shreds to absorb behind the water density and become reason such as big, can sink.

The present invention mixes ratio a kind of comparatively complete, feasible method is provided for fast, accurately measuring in the pipe tobacco sheet and shreds, and the employing of the method can be correct control and mixes the ratio of sheet and shreds in cutting filler the reliable technique parameter is provided.

Embodiment
