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.Detection method more particularly, to a kind of cigarette leaf group degree of mixing.

Background technology

Nicotiana tabacum L. is the primary raw material of Medicated cigarette.All kinds, grade, the Nicotiana tabacum L. of liquor style are carried out reasonably combined, makes up to optimal mass effect, be the main task of cigarette tobacco leaf formulation design work.

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

The inherent quality of Medicated cigarette is mainly determined by fragrance, the factors such as taste, strength, zest, color, gloss of inhaling.These factors are mainly affected by color and the chemical composition thereof of Nicotiana tabacum Lves various in formula.

Nicotiana tabacum L. is as a kind of agricultural product, affected by gene itself, cultivation step, edaphic condition, climatic factor and modulator approach etc. are many, different cultivars, the Nicotiana tabacum L. of different regions the most same plant different parts, all also exist larger difference in quality and style.Therefore, the various fine quality factors of Nicotiana tabacum L., it is impossible to exist only in same or a few Nicotiana tabacum L..The Nicotiana tabacum L. of one kind, its quality factor is often conflicting.As some tabacco fragrance is sufficient, but miscellaneous QI is heavier, zest is bigger；Some Nicotiana tabacum L. strength is moderate, but fragrance is the most sufficient.The Medicated cigarette using the Nicotiana tabacum L. of single variety or single-grade to make, has the mass defect that cannot overcome.Even high-grade Nicotiana tabacum L., it is also difficult to obtain completely satisfactory effect.This different qualities being accomplished by utilizing various Nicotiana tabacum L., chooses optimal tobacco leaf formulation combination, makes the various Nicotiana tabacum Lves of participation formula can maximize favourable factors and minimize unfavourable ones, complement each other, and in concert with play respective effect.

Cigarette composition one is sized, the just sizing of its wool fabric.If put into production for a long time, its quality and style should keep relative stability.The Medicated cigarette being used to certain trade mark is inhaled by consumer, namely get used to its liquor style.If cigarette quality style often changes, consumer will be lost.So, cigarette tobacco leaf formulation personnel must suitably adjust formula according to the situation of change of quality of tobacco, makes product quality style keep stable.As time goes on, environment and the change of living standard, the consumption habit of consumer also can change, and cigarette tobacco leaf formulation personnel also should suitably adjust formulation composition, to meet consumer demand.

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 homogenizing of chemical composition, thus ensure the concordance of processes, the stability of quality, homogeneity, for stable roll tobacco quality, show that Medicated cigarette style has far reaching significance.

At present mix and join precision mixing allotment of labor's sequence in industry, and the uniformity that adjuvant is in tobacco shred has carried out correlational study, but the research to Primary Processing cigarette leaf group component mixability is rarely reported.

Summary of the invention

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

For solving above-mentioned technical problem, the present invention uses following technical proposals:

The detection method of a kind of cigarette leaf group degree of mixing, comprises the following steps:
