Abstract

The invention discloses a detection method of cigarette tobacco leaf group mixedness. The detection method comprises the following steps of randomly taking 30 samples in all processes as sampling points before shredding under the condition of paper-making reconstituted tobacco as a test marker, wherein each one of the samples has a sample amount of 1000g, carrying paper-making reconstituted tobacco manual-selection separation detection on the samples, and calculating cigarette tobacco leaf group mixedness. The detection method can characterize tobacco leaf group mixedness by detected uniformity of paper-making reconstituted tobacco in the tobacco leaf group and realize scientific, simple, accurate and precise evaluation of cigarette tobacco leaf group mixedness.

Description

A kind of detection method of cigarette leaf group degree of mixing

Technical field

The present invention relates to technical field of cigarette production.More specifically, a kind of detection method of cigarette leaf group degree of mixing is related to.

Background technology

Tobacco leaf is the primary raw material of cigarette.The tobacco leaf of all kinds, grade, liquor style is carried out reasonably combined, and making it to reach best mass effect, is the main task of cigarette tobacco leaf formulation design effort.

The style characteristic of cigarette is determined by factors such as tobacco leaf formulation, PROCESS FOR TREATMENT, flavoring and casing, auxiliary material selections.Tobacco leaf formulation is the prerequisite forming product style feature.

The inherent quality of cigarette determines primarily of fragrance, the factors such as taste, strength, pungency, color, gloss of inhaling.Color and the chemical composition thereof of these factors various tobacco leaf in mainly being filled a prescription affect.

Tobacco is as a kind of agricultural product, affect by itself gene, cultivation step, edaphic condition, climatic factor and modulator approach etc. are many-sided, the tobacco leaf of the even same plant different parts of different cultivars, different regions, quality and style all also exist larger difference.Therefore, the various fine quality factors of tobacco leaf, can not exist only in same or a few tobacco leaf.The tobacco leaf of a kind, its quality factor is conflicting often.As some tabacco fragrance is sufficient, but assorted gas is heavier, pungency is larger; Some tobacco leaf strength is moderate, but fragrance is sufficient not.The cigarette using the tobacco leaf of single variety or single-grade to make, has the mass defect that cannot overcome.Even high-grade tobacco leaf, be also difficult to the effect that acquisition is made us being satisfied with completely.This just needs the different qualities utilizing various tobacco leaf, and choose best tobacco leaf formulation combination, the various tobacco leaves that participation is filled a prescription can be maximized favourable factors and minimized unfavourable ones, be complemented each other, and in concert with play respective effect.

Cigarette composition is once determining, its wool fabric has just been shaped.If put into production for a long time, its quality and style should keep relative stability.Consumer inhales the cigarette being used to certain trade mark, namely get used to its liquor style.If cigarette quality style often changes, consumer will be lost.So cigarette tobacco leaf formulation personnel according to the situation of change of quality of tobacco, suitably must adjust formula, product quality style is made to keep stable.As time goes on, the change of environment and living standard, the consumption habit of consumer also can change, and cigarette tobacco leaf formulation personnel also suitably should adjust formulation composition, to satisfy the demands of consumers.

Cigarette leaf group mixing quality is the basis of constant product quality, improve cigarette leaf group mixing uniformity, be conducive to the equilibrium of processing materials physical behavior, the homogeneous of chemical composition, thus ensure the consistance of processes, the stability of quality, homogeneity, for stable roll tobacco quality, show that cigarette style has far reaching significance.

Join precision to mixing mixing of allotment of labor's sequence in current industry, and the homogeneity of auxiliary material in pipe tobacco carries out correlative study, but the rarely seen report of research to Primary Processing cigarette leaf group component mixability.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of detection method of cigarette leaf group degree of mixing, the method, can science, easy, accurate and exact evaluation cigarette leaf group degree of mixing at the degree of mixing of the uniformity coefficient sign leaf group of Ye Zuzhong by detecting papermaking-method reconstituted tobaccos in leaf group.

For solving the problems of the technologies described above, the present invention adopts following technical proposals:

A detection method for cigarette leaf group degree of mixing, comprises the following steps:

B. on the physics of cigarette, chemical index particularly smoke transportation significantly do not affect;

C. do not exist in raw tobacco material.

D. along with refining losses is smaller, and easily identify.

(2) according to the needs detected, every procedure all can be used as sampling spot (to comprise chopping operation) before production line chopping, and sampling amount is: 1000 grams; Each sampling amount is respectively got 30 samples and is detected;

(3) papermaking-method reconstituted tobaccos is carried out to institute's sample thief and pick separation by hand.

(4) papermaking-method reconstituted tobaccos and tobacco leaf after separation are weighed, and carry out water percentage detection according to YC/T31 " preparation of tobacco and tobacco product sample and determination of moisture Oven Method " respectively;

(5) to the data analysis detected, calculate according to following formula:

X％＝/(W ₁+W ₂)*100 (1)

In formula (1):

X%: be the content of papermaking-method reconstituted tobaccos in sample.
