The invention discloses a method for designing the formulation combination of
tobacco leaf, which comprises the following steps: the
design objective of cigarette products is determined; the requirement for the main
chemical composition of the objective is determined; according to the experience, formulation personnel preliminarily select one representative tobacco leaves respectively from base cigarette, auxiliary material cigarette and filler; according to the similarity of the base cigarette and the compatibility of the auxiliary material cigarette and the filler, the rest
tobacco leaf materials are selected; the final
tobacco leaf materials used for the formulation are determined by the formulation personnel according to the storage rate of tobacco leaf, absolute
degree of association and
smoke panel test; the formulation cost is taken as
evaluation function of fitness, and the proportion of the
chemical composition, the main materials, the auxiliary materials and the filler are taken as constraint condition, the
genetic algorithm is searched. The invention overcomes the deficiency that the prior art can not ensure the aesthetic quality, product style and
flue gas index of the formulation of tobacco leaf to be in accordance with design requirements, and provides a method which supplies multiple formulation combinations that are in accordance with requirements, reduces the cost and lightens the
workload of the formulation personnel, thus being widely applied to the field of cigarette production.
