Problems solved by technology

However, during the rolling process using this method, the tightness of the cigarette samples is usually controlled by hand feeling, which cannot be accurately quantified, and can only be roughly measured for the mass burning rate of the cigarette, resulting in large differences between different samples
Moreover, when using this method to measure the combustion performance of cut tobacco samples of different years and grades in the same production area, the error is also very large, and it is impossible to accurately measure the combustion performance and conduct statistical analysis.

Embodiment 1

[0058] 1. Tobacco leaf sample selection: Select representative samples of different grades (X2F, C3F, B2F grades) in different years (2016, 2017, 2018) in the same production area, and take 500g of each as a tobacco leaf sample.

[0059] 2. Preparation of shredded tobacco samples: remove the stems of each tobacco leaf sample and cut into shredded tobacco with a width of 0.9±0.1 mm, mix well, and take 50 g of each portion as shredded tobacco samples.

[0060] 3. Preparation of balanced shredded tobacco sample: Take the cut shredded tobacco sample and put it in a constant temperature and humidity box, take it out after balancing for 72 hours under standard air conditions (temperature 22±1°C, relative humidity 60±3%), and stir it by hand every 4 hours during this period , to ensure that the moisture, temperature and humidity of the shredded tobacco sample are evenly balanced, and a balanced shredded tobacco sample is obtained.

[0061] 4. Calculation method for the mass of shredd...

Abstract

The invention relates to the technical field of cigarette combustion performance measurement, in particular to a method for measuring a cigarette combustion rate. According to the method for measuringthe cigarette combustion rate, the gram weight of tobacco shreds to be arranged in a filling mode in each cigarette is calculated by measuring filling values of the tobacco shreds, then the cigarettes are quantitatively rolled, and by measuring a mass combustion rate (mg / min), the combustion performance of tobacco leaves can be more accurately and objectively reflected, and statistical analysis is carried out. Compared with a traditional method, the problem of different tightness and uniformity of the cigarettes caused by different filling properties among samples is effectively solved, and the combustion rate of the cigarettes can be accurately measured under the condition of fewer cigarette samples.

Description

technical field [0001] The invention relates to the technical field of measuring the combustion performance of cigarettes, in particular to a method for measuring the burning rate of cigarettes. Background technique [0002] The burning rate of cigarettes is a comprehensive reflection of the burning performance of shredded tobacco. It is closely related to the release of harmful components in cigarette smoke, and directly affects consumers' intuitive experience. Therefore, the research on cigarette burning rate is one of the main means to improve the quality and safety of cigarettes. one. [0003] At present, the method of measuring the burning rate of cigarettes commonly used in the industry is: after balancing the shredded tobacco samples, the cigarette samples are obtained by rolling with a small cigarette machine or by hand, and then a certain length (30mm or 35mm) of the cigarette samples is measured by manual or instrumentation for free smoldering The time taken to ca...
