Cut tobacco screening instrument and cut tobacco structure distribution measuring method

Abstract

The embodiment of the invention provides a cut tobacco screening instrument and a cut tobacco structure distribution measuring method. The cut tobacco screening instrument comprises seven layers of screens, wherein the diameters of screen holes of the first layer of screen to the seventh layer of screen are sequentially reduced from top to bottom; and the diameters of screen holes of the fourth layer of screen, the fifth layer of screen and the sixth layer of screen are replaced according to preset measuring conditions. The method comprises the steps that a cut tobacco sample to be measured isscreened three times, and first screening data, second screening data and third screening data are obtained; according to the first screening data, the second screening data and the third screening data, mass distribution interval data of the cut tobacco sample to be measured is obtained; according to the mass distribution interval data and a cut tobacco cumulative distribution function, cut tobacco structure distribution of the cut tobacco sample to be measured is obtained. According to the cut tobacco screening instrument and the cut tobacco structure distribution measuring method, the screening interval range grade of the cut tobacco sample is increased, obtained cut tobacco size continuous distribution and change condition data are more accurate, and the uniformity of cut tobacco structure distribution is accurately described.

Description

technical field [0001] The invention relates to the technical field of cigarette technology, in particular to a shredded tobacco sieving instrument and a method for measuring the structure distribution of shredded tobacco. Background technique [0002] Tobacco structure is an important factor affecting the quality of cigarettes, and it is one of the key quality indicators that need to be considered in the cigarette production process. The structure of shredded tobacco will directly affect the filling condition of cigarettes in cigarette sticks, and then affect important indicators such as hardness, tip curl, short end and smoke of cigarette products. Therefore, the accurate determination of the structure distribution of shredded tobacco is of great significance in the cigarette manufacturing industry. [0003] At present, the cut tobacco structure detection method commonly used in the industry mainly uses the screening method to separate tobacco cuts of different sizes, and...

Problems solved by technology

[0004] However, because the three-layer sieving method does not have high requirements on the uniformity of the samples, when a small number of samples are processed, the test results will have large deviations; The discrete size distribution of shredded tobacco cannot accurately describe the continuous distribution and variation of shredded tobacco size in different intervals, and the uniformity of the distribution of shredded tobacco structure cannot be described, thus affecting the quality of finished cigarettes
