Embodiment 1

[0030] A method for evaluating the mixing uniformity of cigarette raw materials based on design values, comprising the following steps:

[0031] (1) Sampling and pretreatment of samples: select cigarettes with a design value of 20% mixed ratio of cut stems of a certain specification, and take samples during the production and processing time of a batch, during the packaging process, and take samples every 1 hour, a total of 10 times, each Take 5 cigarettes at a time; the cigarettes you take correspond to the shredded leaves and shredded stems of the cigarette formula used. The formula shredded leaves and shredded stems are dried and crushed through a 40-mesh sieve. Tobacco sticks are equilibrated for 48 hours in an environment of 22°C±1°C and relative humidity of 60%±3%. The moisture content of each sample was determined by the oven method.

[0032] On a dry basis, the formula shredded leaf powder and cut stem powder are mixed according to a certain mass ratio, and the prepa...

Embodiment 2

[0046] A method for evaluating the mixing uniformity of cigarette raw materials based on design values, comprising the following steps:

[0047] (1) Sample collection: Take the shredded leaves and shredded stems of the formula in Example 1, and prepare cigarette samples according to the mixed design value of shredded stems at 30%.

[0048] (2)-(7) are the same as embodiment 1.

[0049] (8) Mixing uniformity of shredded tobacco stems: Determine the theoretical design value of nicotine according to the mixing design standard, select cigarettes at 10 sampling points in one batch, and randomly select 5 cigarettes at each sampling point, a total of 50 samples , removed the filter rod and cigarette paper, measured the dry base nicotine content of cut tobacco in each sample, and substituted it into the model to calculate the design nicotine value, and the relative standard deviation (RSD) was 4.2%, indicating that the method had high precision; The mixing uniformity of the cigarette...

Abstract

The invention relates to the technical field of cigarette processing, in particular to a cigarette raw material mixing uniformity evaluation method based on a design value. The method comprises the following steps of establishing and verifying a mathematical model of a raw material mixing ratio and a nicotine value based on the characteristic of significant difference of characteristic component nicotine of different raw material tobaccos of a cigarette, respectively determining different cigarette nicotine amounts, substituting a designed mixing ratio into the model, and calculating a designed nicotine value, and calculating according to a formula to obtain the mixing uniformity of the cigarette raw materials. According to the method, required equipment and operation treatment are simple,and the required sample amount is small; accurate measurement of the mixing uniformity of cigarette raw materials can be realized; meanwhile, a theoretical design value and a mathematical model established by tobacco characteristic components are innovatively applied to the evaluation of the mixing uniformity of the cigarette raw materials; compared with the average value, the theoretical designvalue is more objective and accurate, the phenomenon of mixing uniformity distortion caused by insufficient sampling amount, overall deviation in the actual production process and the like can be effectively avoided, and technical support is better provided for accurate regulation and control of a cigarette formula and development of a cigarette uniformity technology.

Description

technical field [0001] The invention relates to the technical field of cigarette processing, in particular to a method for evaluating the mixing uniformity of cigarette raw materials based on design values. Background technique [0002] During the cigarette processing process, various raw materials such as shredded tobacco leaves, shredded reconstituted tobacco leaves, shredded stems and expanded shredded tobacco are usually mixed together. The mixing uniformity of different raw materials directly affects the inner quality of cigarette products. The more stable the gas characteristics and sensory quality. In recent years, with the introduction of digitization in cigarette design, the development of characterization methods and technologies for leaf group uniformity has become one of the key research directions in the tobacco industry. [0003] At present, domestic cigarette manufacturers generally use the industry standard "YC / T 426-2012 Determination of Blending Uniformity...
