Method for predicating combustion intensity of cigarettes based on detection of pressure drop

Abstract

The invention discloses a method for predicating the combustion intensity of cigarettes based on detection of pressure drop. The method comprises the following steps: determining mouth-by-mouth pressure drop in a smoking process of a cigarette sample by utilizing a pressure drop detection device; determining combustion surface temperature under a corresponding smoking opening sequence of the cigarette sample by utilizing an thermal infrared imager and extracting all temperature data; taking the mouth-by-mouth pressure drop in the smoking process of the cigarette sample as an independent variable x and the combustion intensity y as a dependent variable to obtain a regression equation of a prediction model of the combustion intensity of the cigarettes; after determining the mouth-by-mouth pressure drop in the smoking process of the cigarette sample, substituting into the prediction model, so as to obtain the predicated combustion intensity of the cigarettes. According to the method disclosed by the invention, an experiment process for determining cigarette combustion property parameters is simplified and a basic detection method of the combustion intensity is supplemented; unstable factors in the determination of combustion temperature are reduced, and a data processing quantity in a traditional combustion temperature detection method is simplified. Furthermore, basic data is provided for guiding cigarette material researches, cigarette combustion and smoking mechanism analysis and cigarette material designing; the method has very strong practicability and wide applicability.

Description

technical field [0001] The invention relates to a method for predicting the burning intensity of cigarettes, in particular to a method for predicting the burning intensity of cigarettes based on detected pressure drop. Background technique [0002] With the continuous development of technology in the tobacco industry, more and more attention has been paid to the characteristic parameters of the cigarette burning process, such as the temperature distribution of the cigarette when it is burned. The temperature distribution during cigarette burning not only affects the chemical composition and content of the main and side stream smoke, but also has a close relationship with the density, draw resistance, air permeability of cigarette paper, and tipping paper. Therefore, an in-depth study of the temperature field distribution during the burning process of cigarettes, and the connection of the temperature field distribution with the draw resistance of cigarettes and the air permea...

Problems solved by technology

Foreign Colard et al. built an experimental device for measuring the pressure drop change during cigarette burning, and compared and analyzed the value predicted by the model with the experimentally measured value. Some scholars also established a mathematical model for predicting cigarette ignition and future Cigarette pressure drop during the ignition process, but there are very few studies on the relationship between the pressure drop and the complex change system of combustion temperature
