Example Embodiment

[0023] Example 1:

[0024] Select 10 different brands of cigarettes, in accordance with the tobacco industry standard YC / T29-1996 "Cigarettes use conventional analysis to determine the total particulate matter and tar with a smoking machine" method, select the cigarette quality and the range of resistance to "average weight ± 0.02g" and "average draw resistance ±49Pa" cigarettes, and use a microwave density moisture analyzer (NW3220, Germany TEWS company) to determine the density of cigarettes (from the tip of the cigarette, a density data can be obtained every 1mm). For each brand of cigarettes, select the average density within 8mm of the front end of the cigarette as "the average density of all samples within 8mm ±5mg / cm 3 "" cigarettes are used as test samples. Before cigarette smoking, the vacuum degree of the infrared spectrum gas pool is 10Pa and the temperature is set to 70℃; the cigarette smoking time is 10s; the FTIR acquisition of the smoke sample signal adopts the cont...

Example Embodiment

[0029] Example 2:

[0030] A cigarette with a high filter ventilation rate with a box label of 1 mg tar and a cigarette circumference of 24.2 mm is selected, and the cigarette is evenly punched in two rows of holes about 9 mm from the end of the filter. Before the experiment, the cigarettes were screened according to the method in Example 1; then, transparent glue was used to seal the holes in sequence along the circumference of the cigarette filter by 4, 8, 12, 16, 20, and 24.2 mm, including the A total of 7 cigarette samples can be obtained from cigarettes with filter plugs; then, according to the national standard GB / T22838.15-2009 "Determination of Physical Properties of Cigarettes and Filter Rods Part 15: Measurement Definition and Measurement Principles of Cigarette Ventilation" Provide the method to determine the ventilation of the filter. The method for measuring the smoke inhalation under a certain cigarette smoking pressure and smoking time is the same as in Example 1....

Example Embodiment

[0033] Example 3:

[0034] Select a kind of cigarette, and screen the average density within 8mm of the tip of the cigarette according to the method of Example 1 to be 215±5, 225±5, 235±5, 245±5, 255±5 and 265±5 mg / cm, respectively 3 Wait for six sets of cigarettes. The method for measuring the smoke inhalation under a certain cigarette smoking pressure and smoking time is the same as in Example 1.

[0035] The relationship between the intensity of the Gram-Schmidt signal measured by FTIR of cigarette smoke and the density of cigarettes see Image 6 .

[0036] Therefore, the method for determining the ease of smoking of cigarettes provided by the present invention can not only quickly and conveniently determine the ease of smoking of cigarettes, but also can be applied to the study of influencing factors of the ease of smoking of cigarettes. Staff improve the smoking quality of cigarette products, especially low-tar cigarette products, and provide a good characterization and techni...

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...
