Abstract

The invention relates to a method for testing the structure of thread tobacco of cigarette, which is characterized in that: a, arranging cigarette into the condition as temperature at 20+-2 Deg. C and humidity is 65+-5%, then taking out the cigarette, to be uniformly divided into two parts, and taking out the thread tobacco from the cigarette; b, inputting two sample thread tobaccos into seven-layer screener to be screened for two times, while the vibration amplitude is 55-70 and the time is 10-20 minutes; c, using laminated weighting, recording the weight of thread tobacco of each layer after each screening, to calculate out the total weight; d, comparing the weight of each layer with the total weight, to obtain the ratio of each layer; e, adding the ratios of same layer of two times of screening, to obtain the average value, to test the ratio of different thread tobacco in the cigarette.

Description

technical field [0001] The invention relates to cigarette technology, in particular to a method for measuring the structure of shredded tobacco in a cigarette for measuring the distribution ratio of shredded tobacco of different sizes. technical background [0002] In cigarette production, it is generally considered that the structure of shredded tobacco is an important indicator affecting the quality of crimping. The structure of shredded tobacco directly affects the weight of a single cigarette. The fluctuation of the weight of a single cigarette has a great influence on the hardness, tar content, draw resistance, sensory quality and cut tobacco consumption of the cigarette. Therefore, enterprises often adopt the method of improving the structure of shredded tobacco to improve the crimping quality of cigarettes and reduce the weight of a single cigarette. [0003] In recent years, with the continuous deepening of cigarette technology research, especially the significant ...
