Embodiment 1

[0030] Take brand A production sample 1, measure the tobacco density distribution by microwave method, and calculate the Δρ value to be 89.40 mg / cm 3 , and substituted into the above equation, the predicted head drop rate is 60.51%, and the measured head drop rate is 58%.

Embodiment 2

[0032] Taking the production sample 2 of brand A (changing the structure of the leveling disk, and fixing other parameters), the density distribution of cut tobacco was measured by microwave method, and the calculated Δρ value was 70.18 mg / cm 3 , and substituted into the above equation, the predicted head drop rate is 27.32%, and the measured head drop rate is 28%.

Embodiment 3

[0034] Take the production sample 3 of brand A (adjust the size distribution of shredded tobacco, and fix other parameters), measure the density distribution of shredded tobacco by microwave method, and calculate the value of Δρ to be 64.60 mg / cm 3 , and substituted into the above equation, the predicted head drop rate is 18.77%, and the measured head drop rate is 20%.

Abstract

The present invention relates to a method for predicting cigarette combustion cone falling tendency. The method comprises following steps: taking a plurality of cigarettes of a same type, testing tobacco density distribution of each cigarette, and analyzing and calculating to obtain density difference between a highest density point and a lowest density point in a falling section of each cigarette; testing a combustion cone falling rate of each cigarette under same conditions, and obtaining the combustion cone falling rate of each cigarette; drawing a correlation curve between the combustioncone falling rate and the density difference of the cigarette model; and testing the tobacco density distribution of a cigarette to be tested of the same type, obtaining density difference between a highest density point and a lowest density point in a falling section of the cigarette, and calculating the combustion cone falling rate of the cigarette to be tested according to the correlation curve. The method firstly predicts the combustion cone falling rate of the cigarette through the tobacco density distribution, is simple and accurate, has high accuracy, and can greatly improve the efficiency of analysis and detection; and in addition, can mechanically reveal influence of the tobacco structure distribution on the cigarette combustion cone falling behavior.

Description

technical field [0001] The invention relates to a method for predicting the tendency of cigarette burning cone drop, in particular to a method for rapidly predicting the tendency of burning cone drop of slim cigarettes. Background technique [0002] Compared with conventional cigarettes, slim cigarettes have obvious advantages such as small circumference, less shredded tobacco consumption, low coke and high quality, and reduced harm, which are of great significance to the sustainable development of the industry. However, some slim cigarettes have a more obvious combustion cone drop phenomenon during the process of flicking the ash, which reduces the consumption experience of slim cigarettes. [0003] Existing test methods for the tip drop rate of slim cigarettes mainly use the tapping method to simulate the action of flicking the ash by hand, and the experimental conditions are difficult to simulate the real environment (such as tapping force, tapping position, tapping time,...
