The dynamic smoke resistance of the whole leaf rolled cigar is usually measured by YC/T461-2013 definition and standard condition of cigar smoking machine for routine analysis, and the dynamic smoke resistance of the cigarette can be measured. By measuring the dynamic suction resistance of the whole leaf cigar, the fluctuation condition of the dynamic suction resistance of the whole leaf cigar in the combustion process can be known. Different from the traditional cigarettes, the internal tobacco shred filling property is uniform, the number of the suction ports is fixed, and the number of the suction ports is usually 7-10, but the number of the suction ports of the whole-leaf cigar rolled by the same specification is greatly different due to various factors such as raw material varieties, manual rolling, manufacturing process and the like. In this case, when the difference in the number of suction ports of the whole leaf rolled cigar products of the same specification is large, it is difficult to perform research and analysis of the related indexes such as dynamic suction resistance and density. Therefore, a reasonable dynamic resistance detection method needs to be established to solve the similar problems, and the method has important significance for the research and analysis of the whole leaf cigar rolling.

step 2, setting equipment parameters according to the test sample: duration of suction: 1.5s, aspiration frequency: 40 s/bite;
step 3, selecting M samples to be fixed on a holder of the smoking machine one by one, wherein the angle formed by a longitudinal axis of the test sample and a horizontal plane is as follows: the end of the cigarette butt is lower than the other end by not more than 10 degrees and higher than the other end by not more than 5 degrees; igniting the test samples by using a hand-held electric igniter without contacting or pre-burning the test samples, wherein the ignition of each test sample reaches the combustion of the whole end face of the combustion end of the test sample;
and 4, performing axial data processing on the mouth-by-mouth dynamic suction resistance data and the burning length of the mouth-by-mouth burning cone of each test sample to obtain dynamic suction resistance data when each test sample burns with the same length.
Further, in the step 2, the smoking machine is a limited suction type smoking machine, the connecting pipeline between the smoke catcher and the suction mechanism should have as small airflow resistance as possible, the pressure drop of the total circulating pipeline between the end of the cigarette butt and the suction mechanism is not more than 300PA before suction, the total volume of all the suction channels is not more than 125mL, and the catcher filter disc needs to be replaced before each test, and the flow is calibrated.
In the step 3, in the testing process, the length of the cigarette combustion cone after each port of suction is measured and recorded; after the test sample is sucked into the N ports, when the combustion cone reaches the same position mark of each test sample butt, the suction is manually stopped, and the air is prevented from being continuously sucked through cigars; and obtaining the mouth-by-mouth dynamic suction resistance data of M test samples and the mouth-by-mouth combustion cone combustion length data of each test sample.
In the step 4, the axial data processing method is as follows: according to the test requirement, setting a same burning length L of each opening, taking the average value (X1+X2)/2 of the nearest two dynamic resistance data (X1 and X2) at each L length to obtain the dynamic data at the current L length, and finally obtaining the dynamic data of each cigarette at each burning length L.
