Problems solved by technology

[0003] At present, domestic tobacco scientific and technological workers have begun to conduct relevant research on the measurement of dynamic draw resistance during cigarette burning. However, the research on the stability evaluation of dynamic draw resistance during cigarette burning is still in its infancy. There are few methods for evaluating the stability of draw resistance
The Chinese invention patent (CN201611189773.4) adopts the method of one-way analysis of variance to determine whether the dynamic draw resistance of the brand cigarette is stable by calculating the P value of a set of dynamic draw resistance data. To be precise, this method can only be determined by the P value. To determine whether the dynamic draw resistance data of a certain brand of cigarettes is significant, but it is not possible to compare the dynamic draw resistance stability of two different brands of cigarettes

Abstract

The invention discloses a method for evaluating dynamic draw resistance stability during a cigarette combustion process. The method comprises the following steps: several cigarettes are placed under same experiment environment for balance processing, and taking test samples with quantity being m by aiming at the cigarettes having a same specification; taking the test samples and fixing the test samples in a single-pore channel smoking machine one by one, igniting the test samples, and recording the pressure data and time data to obtain the puff-by-puff dynamic draw resistance data of the test samples; processing the dynamic draw resistance data of the cigarette, and evaluating the dynamic draw resistance stability of the cigarette according to the constructed evaluate index. The method is simple and feasible, and can be used for evaluating the dynamic draw resistance stability during the cigarette combustion process in a quantification mode.

Description

technical field [0001] The invention belongs to the technical field of cigarette quality evaluation, and in particular relates to a method for evaluating the stability of dynamic draw resistance during the burning process of cigarettes. Background technique [0002] The sensory quality of cigarettes is not only affected by important indicators such as cigarette weight, draw resistance, ventilation rate, hardness, and pressure drop under static conditions, but also by indicators such as draw resistance, ventilation rate, and pressure drop during cigarette smoking. During the smoking process of cigarettes, the dynamic draw resistance directly affects consumers' perception of the sensory quality of cigarettes, and is also one of the important factors affecting the chemical composition of smoke. [0003] At present, domestic tobacco scientific and technological workers have begun to conduct relevant research on the measurement of dynamic draw resistance during cigarette burning....
