Building and Application of Calculation Model for Determination of Cut Tobacco Content of Individual Cigarettes

In order to effectively control the cigarette making process and improve the overall quality of cigarettes, the calculation model for determination of the cut tobacco content of individual cigarettes was established by performing data statistics and analysis on the main factors affecting the cut tobacco content of cigarette samples with different specifications, and the making process was controlled to test the weight and suction resistance of cigarettes before and after the control. The results show that 1. The correlation coefficient R of the calculation model built is 0.987, R2 is 0.973, and the correlation between the cut tobacco content of individual cigarettes and each affecting factor is good; 2. After the cut tobacco content of individual cigarettes is converted into the value corresponding to the target weight control, the standard errors of weight and suction resistance as well as the average value of weight and suction resistance have been greatly reduced. Main Conclusion: 1. The calculation model for determination of the cut tobacco content of individual cigarettes has a high accuracy, and it is suitable to be popularized; 2. When the cut tobacco content of individual cigarettes is converted into the value corresponding to the target weight control, the relative physical indicators such as the weight and suction resistance of the cigarettes fluctuate less, and their performance is more stable, which is conducive to the improvement of the overall quality of cigarettes.
