Abstract

Ash line width affects consumers' judgment of cigarette quality. In this paper, the width of ash line is determined and its calculation method is studied, which is tested by full vision testing equipment. The test results show that the width of ash line of cigarettes with the same crack rate is different, which can be used as an index to measure the appearance quality of cigarettes in the process of combustion. The average ash line width of the measured sample is larger for common cigarettes than for medium and slim cigarettes. In the process of moving backward with the combustion section, the carbonization line is affected by factors such as cut tobacco structure, filling density, cigarette paper and leaf group formula. The equipment for measuring cigarette combustion appearance quality with full vision adopts the method of three-side photography in the process of measuring indicators, and the test results of three-side photography of the same cigarette have a large difference rate, which is better than single-side photography.
