Description

A kind ofly measure the method that expanded cut stem in the pipe tobacco is mixed ratio

Technical field

The present invention relates to a kind of method that expanded cut stem in the pipe tobacco is mixed ratio of measuring.

Background technology

Offal accounts for about 30% of tobacco leaf total amount, is the main accessory substance of tobacco industry, because tobacco stalk fibre cellulose content height, compositions such as sugar alkali are lower, usually the filling value that is used as stem or laminates and prop up with the increase cigarette helps falling Jiao, and this also is one of main path of offal utilization.

Respectively mixing in cutting filler joined the owner and will be comprised: leaf silk, expansive cut tobacco, expanded cut stem, paper process thin slice, roll-in method thin slice, sheet and shreds etc.Present domestic tobacco enterprise adopts the demi-inflation stem as the batching pipe tobacco and roll into tobacco product and prop up usually, but mix a certain proportion of expanded cut tobacco when cutting filler in after, smoke components can change, and influences bigger to the aesthetic quality of cigarette.Therefore, the ratio of mixing expanded cut stem during control cuts filler is to significant with control finished product tobacco quality.

Chinese patent application 200610018051.2,200610018050.8,200910065223.5 all be to utilize the middle difference that cuts filler to mix the difference that combo is divided the tobacco apparent density, adopting the method that disposes the different densities organic solvent that difference in cutting filler is mixed the combo branch separates, and then obtain to mix and join thing and in cutting filler, mix mixing ratio, since the density of expansive cut tobacco with cut filler in other mix that to join the thing difference bigger, therefore utilize the method for above-mentioned patent effectively to separate to expansive cut tobacco, but the density difference of expanded cut stem and Ye Si and sheet and shreds is very little in the real process, is difficult for selecting the organic solvent of proper density that it is separated.

And the method that Chinese patent application 200610018085.8 relates to is by dividing different external appearance characteristics to carry out craft to select according to respectively mixing combo in cutting filler under magnifier, therefore the numerous and diverse and inefficiency of process need find a kind of simple effective method that expanded cut stem in the pipe tobacco is mixed ratio and measure.

Summary of the invention

Expanded cut stem 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:

A kind ofly measure the method that expanded cut stem in the pipe tobacco is mixed ratio, this method comprises the steps:

A, manually mix ratio expanded cut stem and all the other components that cut filler are mixed and joined, and record is set and mixed ratio value in setting;

B, will mixing pipe tobacco after joining, to put into temperature be 20 ± 2 ℃, and humidity is balance 24 ± 2 hours in 65% ± 5% the environment;

C, utilize the total alkaloid content of pipe tobacco after the flow analysis instrument determination step b balance;

D, utilize the total alkaloid content value that step c records and the ratio value of mixing of step a record to carry out match, obtain expanded cut stem and mix scale prediction model: Y=R1-R2*X,

In the formula: Y: be the ratio of mixing of expanded cut stem

R1, R2: be concrete fitting parameter

X: be total alkaloid content;

E, get real process and need measure expanded cut stem and mix cutting filler of ratio, putting it into temperature is 20 ± 2 ℃, and humidity is balance 24 ± 2 hours in 65% ± 5% the environment;

F, utilize the total alkaloid content of pipe tobacco after the flow analysis instrument determination step e balance;

G, the expanded cut stem that utilizes steps d to obtain are mixed the scale prediction model, calculate the real process expanded cut stem that cuts filler and mix ratio.

The assay method of total alkaloid described in the present invention, according to tobacco business standard YC/T160-2002 tobacco and tobacco product total alkaloid mensuration---continuous flow method is measured.

The present invention mixes ratio for expanded cut stem in the simple and effective mensuration pipe tobacco a kind of comparatively complete, feasible method is provided, the employing of the method can be correct control cut filler in the ratio of mixing of expanded cut stem technical parameter is provided, and the physical quality and the aesthetic quality that can be the stable roll tobacco product provide support.
