Abstract
The invention relates to a method for testing the doping ratio of expanding thread of thread tobacco, which comprises: a, selecting organic solvent with effumability, and adjusting its density range as 0.83+-0.02; b, arranging the cigarette into the condition with the temperature as 20+-2 Deg. C and the humidity as 65+-5% to be balanced for 24+-2 hours; then taking out the thread tobacco from cigarette to be weighted as W; c, selecting out the leaf thread from the thread tobacco; d, arranging leaf thread into container, adding adjusted solvent to be mixed and laid for 1-3 minutes, then taking out the expanding leaf thread floating on the liquid, to be baked in bake stove at 90-110Deg. C, to be weighted and recorded as P; e, comparing the weight P and the total weight W, to calculate out the doping ratio of expanding leaf thread. The invention can support the test of doping ratio of expanding thread.
Description
Technical field
The present invention relates to a kind of method that expansive cut tobacco in the pipe tobacco is mixed ratio of measuring, relate in particular to and a kind ofly separate expansive cut tobacco and unexpansive leaf silk in the pipe tobacco and measure the method that expansive cut tobacco in the pipe tobacco is mixed ratio.
Technical background
Improving constantly along with human civilization advance and living standard in recent years, smoking is violent further with healthy contradiction, people pay attention to further to the security of cigarette product, and silk leaf expansion is used by domestic and international many cigarette enterprises as a kind of production technology of maturation.It improves tobacco structure and fillibility for reducing coke tar in cigarette and single leaf consumption, improves cigarette sensory evaluation index, rationally utilizes the tobacco leaf resource to have material impact.
At present, domestic cigarette enterprise generally adopt part leaf silk after expanding as the batching pipe tobacco and roll into cigarette and prop up, this method can obtain higher filling value.After mixing a certain proportion of expansive cut tobacco in the pipe tobacco, variation has taken place in smoke components.The weight of Cigarette, cigarette prop up burns and sucks tar content that a mouthful number, cigarette prop up and nicotine etc., all along with mix in the pipe tobacco expansive cut tobacco ratio progressively raising and progressively descend.Therefore, the ratio of mixing expansive cut tobacco during the control cigarette props up has great importance for the quality index that the control cigarette props up.But up to now, but also do not have a kind of suitable fast measuring cigarette prop up in expansive cut tobacco mix the method for ratio.
Summary of the invention
Purpose of the present invention provides a kind of fast measuring expansive cut tobacco to mix the method for ratio at existing problem in the above-mentioned prior art just.
Purpose of the present invention can realize by following technique measures:
The method that expansive cut tobacco is mixed ratio in the mensuration pipe tobacco of the present invention comprises the steps:
A, select volatile organic solvent for use, allotment solvent density scope is 0.83 ± 0.02;
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, choose the leaf silk in the pipe tobacco;
D, the leaf silk is put into container, add deployed solvent, leave standstill after the stirring and take out the expansive cut tobacco that swims on the liquid level after 1～3 minute, put into baking oven after oven dry under 90～110 ℃ the condition, the record of weighing, and be designated as P;
E, the expansive cut tobacco weight P that obtains after will weighing compare with pipe tobacco general assembly (TW) W, can calculate smoke prop up in expansive cut tobacco mix mixing ratio.
Calculate cigarette prop up in the mixing mixing ratio and can be calculated as follows of expansive cut tobacco:
Y％＝P/W*100％。
In the formula: Y: be the mixing ratio of mixing of expansive cut tobacco
P: be floating after expansion leaf silk net weight
W: be pipe tobacco net weight before floating
Organic solvent described in the present invention be by ethyl acetate and cyclohexane by volume 1:2 mix to join and form; Also can be by ethyl acetate and ethanol by volume 2:1 mix to join and form, can also be by acetone and methylene chloride by volume 7:1 mix to join and form.
The present invention mixes ratio a kind of comparatively complete, feasible method is provided for fast, accurately measuring in the pipe tobacco expanded cut tobacco, the employing of the method can be correct control cigarette and mixes the ratio of expansive cut tobacco in propping up the reliable technique parameter is provided, the quality index of propping up for the control cigarette has great importance, and can promote the inherent quality of the physical quality and the product of China's cigarette products on the whole.
