Embodiment 1

[0027] Determination of Ash Value of Cigarette Package in Smoldering State

[0028] Place the cigarette to be tested in an upright position in a well-lit and shadowless lighting environment, and connect the filter of the cigarette to the burning seat of the smoking machine. Light the cigarette and turn on the smoking machine to make the cigarette burn completely under smoldering conditions. When the cigarette is smoldering to a distance of 3mm from the tipping paper, turn off the smoking machine, use a digital camera with more than 5 million pixels and a macro function, and focus on the middle of the ash package at a distance of 150mm from the ash package, and use the macro mode Capture digital images (see figure 1 ). Input the collected image into the computer, start the ImageJ software, open the digital image file, first click Image->Adjust->Threshold, set the threshold for analyzing the image, then select the analysis area of ​​the analyzed image, click set, Click Analyz...

Embodiment 2

[0030] Repeat the operation of embodiment 1, measure the cigarette of another brand, the results are shown in image 3 , Figure 4 . Depend on Figure 4 It can be seen that, in the ash content of the cigarette, the content of the part with poor ash coating condition accounts for 14.4618%.

Embodiment 3

[0032] Determination of Ash Value of Cigarette Packs Satisfied with ISO / FTC Smoking Conditions

[0033] Repeat Example 1, with the following differences: choose another brand of cigarettes to measure, start the smoking machine, and smoke once at intervals of 60s according to the 35ml suction capacity of the simulated human normal smoking state (ISO / FTC). The smoking duration is 2s, and the cigarette smoking process is completed. The collected digital images and final measurement data are shown in Figure 5 , 6 . It can be seen from the figure that the content of the part with poor ash inclusion in the ash accounts for 11.0316%.

Abstract

The invention discloses a method for measuring the wrapped ash state after the burning of the cigarettes. The method comprises the following steps: under the shadowless lighting environment with good light, the real smoking state is stimulated; a digital camera is used to collect the images of the wrapped ashes generated by the burning of cigarettes; and the collected images are input in a computer and analyzed by the ImageJ software to obtain the corresponding wrapped ash values. According to different wrapped ash values, the ash-wrapping performance of the brand cigarette can be known. The invention creatively combines the photographic technology with the ImageJ software and quantizes the wrapped ash state according to the area proportion under the artificial smoking and smoldering conditions of cigarettes, and the obtained values are beneficial to intuitively perform the objective evaluation of the wrapped ash index. The method is simple and practical, and has better experimental reproducibility and good application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette performance analysis, and in particular relates to a method for measuring the ash-covered state of a cigarette after burning. Background technique [0002] Cigarettes are a complex mixture of tobacco, additives, filters, etc. The combustion process involves more complex chemical reactions. Different types and brands of cigarette products have many differences in the ash produced after burning cigarettes due to the differences in cut tobacco raw materials, auxiliary additives, flavors and fragrances, filter material and length, burning conditions and other factors. At present, the ash quality of cigarettes produced after burning is limited to the subjective evaluation method of visual observation combined with verbal description, and there is no quantitative evaluation method. How to more accurately measure the quantitative index of cigarette pack ash and improve the quality of cigarettes has be...
