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.
