Abstract
The invention relates to a method for measuring a blending ratio of expanded cut stems in cut tobacco. The method comprises the following steps: (a) putting the cut tobacco into an environment with the temperature of 22+/-1 DEG C and the humidity of 60+/-3 DEG C for balancing for 24 hours, taking the cigarettes out, taking out the cut tobacco in the cigarettes, weighing and recording as T; (b) putting the cut tobacco into a container filled with liquid nitrogen, stirring and taking the expanded cut tobacco floating on the liquid level; (c) manually picking out the expanded cut stems in the expanded cut tobacco, putting the expanded cut stems into the environment with the temperature of 22+/-1 DEG C and the humidity of 60+/-3 DEG C for balancing for 24 hours, weighing and recording as W; and (d) comparing the weighed expanded cut stems W with the weight T of the cut tobacco, and calculating the blending ratio of expanded cut stems in cut tobacco. The invention provides a convenient and feasible method for separating the expanded cut stems in the cut tobacco and determining the doping ratio.
Description
Technical field
The present invention relates to the assay method of expanded cut stem mixed ratio example in a kind of pipe tobacco, be specifically related in a kind of tobacco shred the assay method of expanded cut stem mixed ratio example in expanded cut stem and unexpansive stem and pipe tobacco.
Background technology
Along with people are to healthy pay attention to day by day, the security that improves smoking has become the common recognition of tobacco industry.World tobacco industry starts towards the future development of low consumption, low tar, low cost, high-grade, high benefit.Expanded cut tobacco is the pipe tobacco after expansion technique is processed, and comprises expansive cut tobacco and expanded cut stem.Expanded cut stem technology is as a kind of production technology of maturation, by tobacco business widespread use.In cigarette shreds formula, expanded cut stem, generally as simple inserts, can reduce the pipe tobacco consumption of cigarette, reaches the effect reducing costs.Expanded cut stem is mainly reflected in the impact of cigarette: use the expanded cut stem of different proportion, can obtain the cigarette of different tar contents; Can control cigarette burning rate, the stem tissue looseness after expansion, completely, burning rate is accelerated in burning, and cigarette puff number reduces.Therefore, control in pipe tobacco expanded cut stem mixed ratio example for controlling cigarette quality stability important in inhibiting.
The method > > (CN 1885003A) that mono-kind of Chinese patent < < measures tobacco shred ratio in cigarette discloses the assay method of expanded cut stem mixed ratio example in a kind of pipe tobacco.This method, in full pipe tobacco formula, utilizes magnifier to pick out expanded cut stem according to the special external appearance characteristic of expanded cut stem, has slow problem.
Summary of the invention
The object of the invention is, for above-mentioned existing problems deficiency, provides the assay method of expanded cut stem mixed ratio example in a kind of pipe tobacco, and the method is easy and simple to handle, quantitatively accurate.
For achieving the above object, the present invention takes following technical scheme: in pipe tobacco, the assay method of expanded cut stem mixed ratio example contains following steps:
A, pipe tobacco is put into 22 ± 1 ℃ of temperature, humidity is balance 24 hours in the environment of 60 ± 3 ℃, then take out cigarette, and pipe tobacco in cigarette is taken out, and the record of weighing, and be designated as T;
