Determination method for cigarette ash column shrinkage ratio

Abstract

The invention discloses a determination method for a cigarette ash column shrinkage ratio. The method comprises the following steps: vertically placing a cigarette on a detector for the wrapped ash of the cigarette, with the lap of the cigarette being inward; subjecting the cigarette to static burning or standard smoking until the cigarette burns to a designated position and carrying out shooting; then measuring the area of an ash column obtained after burning; and calculating the variation extent of the area (S) of the ash column obtained after burning and the area (s) of the cigarette before burning. The cigarette ash column shrinkage ratio (beta) is calculated according to the equation that beta is equal to (S-s)/S * 100%. The greater the value of the cigarette ash column shrinkage ratio is, the higher the cigarette ash column shrinkage ratio is. The determination method for the cigarette ash column shrinkage ratio in the invention employs a repeatable standardized process in each step and is not prone to influence of the skill, experience and subjective consciousness of technical staff, so detection data is objective and standard, and the method can be used for accreditation and standardized authentication of the technical indexes of cigarette performance in the cigarette industry.

Description

technical field [0001] The invention belongs to the technical field of cigarette detection and analysis, and in particular relates to a method for characterizing the ash shrinkage rate of cigarettes by measuring the shrinkage degree of the ash column after the cigarettes are burned. Background technique [0002] The ash shrinkage rate refers to the degree of shrinkage of the ash column of the cigarette after burning, and is an important indicator for evaluating the quality of the cigarette pack ash. With the continuous development of technology in the cigarette industry and the continuous improvement of people's living standards, consumers are now paying more and more attention to the state of cigarette ash after smoking, in addition to paying attention to the taste of cigarettes as always. The ash shrinkage rate will directly affect the overall condition of the cigarette pack ash. For cigarettes with a good ash shrinkage rate, the cigarette paper and cut tobacco can be bett...
