Problems solved by technology

Therefore, in order to obtain accurate sensory evaluation results of cigarette smoking ease, a large number of people need to be organized to smoke cigarettes for each evaluation. This method not only consumes a lot of manpower and material resources, but also has low efficiency. Therefore, its Specific applications are very limited

Embodiment 1

[0024] Select 10 kinds of cigarettes of different brands, according to the tobacco industry standard YC / T29-1996 "Determination of total particulate matter and tar by smoking machine for routine analysis of cigarettes", select the cigarette quality and draw resistance range as "average cigarette weight ± 0.02g” and “average draw resistance ±49Pa” cigarettes, and use a microwave density moisture analyzer (NW3220, Germany TEWS company) to measure the cigarette density (starting from the front end of the cigarette, a density data can be obtained every 1mm). For each brand of cigarettes, the average density within the 8mm range of the front end of the selected cigarette is "the average density of all samples within the range of 8mm ± 5mg / cm 3 "Cigarettes were used as test samples. Before cigarette smoking, the vacuum degree of the infrared spectrum gas pool was 10Pa, and the temperature was set at 70°C; the cigarette smoking time was 10s; 2min, the spectral scanning range is 4000-...

Embodiment 2

[0030]Select a cigarette with a box label tar content of 1mg and a cigarette with a circumference of 24.2mm and a high filter ventilation rate. The cigarette is evenly punched with two rows of holes at a distance of about 9mm from the end of the filter. Before the experiment, the cigarettes were screened according to the method of Example 1; then, use transparent glue to seal holes along the circumference of the cigarette filter at 4, 8, 12, 16, 20 and 24.2 mm, so that the A total of 7 cigarette samples can be obtained from cigarettes with filter plug holes; then, according to the national standard GB / T22838.15-2009 "Determination of Physical Properties of Cigarettes and Filter Rods Part 15: Determination Definition and Measuring Principle of Cigarette Ventilation" Provides a method for determining filter ventilation. The method for determining the amount of smoke inhaled under certain cigarette puffing pressure and puffing time is the same as that in Example 1.

[0031] The ...

Embodiment 3

[0034] Choose a kind of cigarette, according to the method of embodiment 1, screen the average density within the range of 8mm of the front end of the cigarette to be 215 ± 5, 225 ± 5, 235 ± 5, 245 ± 5, 255 ± 5 and 265 ± 5 mg / cm respectively 3 Wait for six groups of cigarettes. The method for determining the amount of smoke inhaled under certain cigarette puffing pressure and puffing time is the same as that in Example 1.

[0035] For the relationship between the Gramm-Schmidt signal intensity measured by FTIR of cigarette smoke and the cigarette density, see Figure 6 .

[0036] Therefore, the method for measuring the ease of smoking of a cigarette provided by the present invention can not only measure the ease of smoking of a cigarette quickly and conveniently, but also can be applied to the study of influencing factors of the ease of smoking of a cigarette, thereby providing a valuable contribution to tobacco science and technology. It provides a good characterization mea...

Abstract

The invention discloses a determination method for a suction easiness degree of a cigarette. The determination method has the technical characteristics that the suction easiness degree of the cigarette is defined by certain cigarette suction pressure and effective cigarette suction amount under suction time; the cigarette suction pressure is superficially characterized by a suction vacuum degree before cigarette suction; and the effective cigarette suction amount is superficially characterized by adopting a fourier transform infrared spectrum (FTIR) method through signal strength of a Gram-Schmidt spectrum measured by continuous scanning. The determination method disclosed by the invention can do scientific and simple definition on the suction easiness degree of the cigarette and can conveniently apply an instrument analysis manner to measure; and the fourier transform infrared spectrum method is used for determining the effective cigarette suction amount and the determination method has the advantages of simplicity in operation, fast analyzing speed, high sensitivity and good experiment repeatability.

Description

Technical field: [0001] The invention relates to a method for measuring the ease of smoking a cigarette. Background technique: [0002] With the continuous advancement of my country's cigarette harm and tar reduction projects, low-tar, especially ultra-low-tar cigarettes will occupy a higher and higher proportion in the market. From a technical point of view, there are many technical measures that can be used to reduce the harm and tar of cigarettes, such as agricultural measures, chemical measures and physical measures. Agricultural measures need to develop new low-harm tobacco leaf raw materials, and their specific application cycle is often longer; chemical measures need to evaluate the toxicology of exogenous additives, and the economic cost is relatively high; physical measures include extending tipping paper and improving filter ventilation. Due to the obvious effect and quick effect, it is a widely used cigarette harm reduction and coke reduction technology in the cu...
