Problems solved by technology

[0006] Among them, it is considered that the tar reduction rate and nicotine reduction rate are plotted against the filter ventilation rate, and the slope is 1, but after research, this is for the mixed type leaf group, and for most of the flue-cured tobacco type leaf groups, the slope is much smaller than 1, Using this formula to predict flue-cured cigarettes, the accuracy is not high enough

Abstract

The invention relates to a method for correcting a predictor formula for conventional tar and nicotine in cigarettes, and belongs to the technical field of tobacco. The method mainly comprises the following steps: by lofting research, the reduction rate of the ventilation rate of a filter tip by the tar and nicotine is worked out, the reduction rate is corrected in the predictor formula for cigarette tar and nicotine in cigarettes, so that the corrected formula can be used for cured tobacco type cigarettes and cigarettes of any tobacco blending formula. After being corrected, the predictor formula can improve the prediction precision of the tar and nicotine in cigarettes greatly; and when used to design products, the corrected formula can save design cost and test cost of the products, thereby greatly improving the scientificity of cigarette product development.

Description

Technical field: [0001] The invention relates to a method for correcting traditional cigarette tar and nicotine prediction formulas. It belongs to the technical field of tobacco. Background technique: [0002] Traditional tar prediction formula: [0003] Cigarette tar amount = cigarette tar amount × (1- filter ventilation rate) × (1- filter tar filtration efficiency); [0004] Traditional nicotine prediction formula: [0005] Cigarette nicotine content = nicotine content of cigarette sticks × (1-filter ventilation rate) × (1-filter nicotine filtration efficiency); [0006] Among them, it is considered that the tar reduction rate and nicotine reduction rate are plotted against the filter ventilation rate, and the slope is 1, but after research, this is for the mixed type leaf group, and for most of the flue-cured tobacco type leaf groups, the slope is much smaller than 1, Using this formula to predict flue-cured tobacco type cigarettes, the accuracy is not high enough. ...
