Embodiment 1

[0033] Example 1: A certain domestic slim cigarette brand 1 and brand 2, comparative analysis of the uniformity of cigarette density distribution of different slim cigarette brands.

[0034] Specific steps are as follows:

[0035] 1. Determination of standard density distribution data of cigarettes:

[0036] (1) Calibrate instrument parameters:

[0037] Take a number of 20 samples of cigarette brand 1 and cigarette brand 2, and mark them respectively.

[0038] Cigarette moisture correction: test 10 cigarettes with microwave moisture density analyzer MW 3220, and store the results under the INFO option in the result menu; use standard laboratory methods to determine the average value of tobacco moisture in 10 cigarettes measured by MW 3220 ;Compare the moisture measured by the MW 3220 with the moisture determined in the laboratory and determine the deviation. According to this method, the moisture content of cigarette brand 1 and cigarette brand 2 is corrected respectively, ...

Embodiment 2

[0046] Example 2: Compare and analyze the uniformity of cigarette density distribution of different conventional cigarette brands for a certain domestic conventional cigarette brand 3 and brand 4.

[0047] 1. Determination of standard density distribution data of cigarettes: Same as Example 1.

[0048] 2. Drawing of cigarette density distribution curve: same as example 1, see figure 2 .

[0049] 3. Evaluation of standard density distribution uniformity of cigarettes:

Abstract

The invention discloses a quantitative evaluation method for cigarette density distribution uniformity. The method comprises the following steps: drawing a cigarette density distribution curve according to the characteristic that the cigarette density distribution is generally in a two-end dense distribution manner; extracting cigarette density data; and performing comprehensive evaluation on the cigarette density distribution uniformity according to the established evaluation index. The method disclosed by the invention has the characteristics of simplicity and feasibility, can realize quantitative evaluation of the cigarette density distribution uniformity and has significances on cigarette designing and coiling process.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of cigarette product quality detection, and in particular relates to a characterization method for evaluating the uniformity of cigarette density distribution [0003] Background technique: [0004] During the cigarette production process, the density distribution of the tobacco bundle changes after the cut tobacco passes through the suction forming system of the crimper, and the density of the lit end of the cigarette is higher than that of other parts. The density distribution of cigarettes is one of the important indicators affecting the quality of cigarettes. It not only affects physical indicators such as weight, hardness, draw resistance, and amount of filaments at the end of cigarettes, but also affects the release of harmful substances in cigarette smoke. It will affect the sensory quality in the process of cigarette consumption, and then affect consumers' acceptance of cigarette products. Th...
