Background
The formula threshing and redrying processing is a process of mixing and processing the primary flue-cured tobacco leaves with different producing areas, parts and grades according to the proportion, the physical and chemical indexes and the compatibility of the smoking style set by a cigarette enterprise. The problems of difficult control of formula precision, low raw material utilization efficiency, complex production material preparation organization mode and the like exist in the process of realizing formula threshing based on the existing threshing and redrying process mode, so that the serious defect of the quality of finished tobacco leaves after threshing and redrying can be caused, the quality of finished tobacco leaves (modules) is inconsistent with the original design, and the task of formula threshing cannot be finished.
The formula threshing is actually the combination of different producing areas and different grades with the same style, and even the combination of tobacco leaves at different parts can be generated. The physical characteristics of tobacco leaves in all grades are inconsistent, so that the optimal processing parameters in the threshing and redrying process are inconsistent. The existing formula threshing is to compare a formula module with a grade of tobacco leaves, and process the tobacco leaves according to a group of parameters, taking a leaf-stem separation procedure as an example: the first-stage threshing may cause full separation of leaves and stems of tobacco leaves of a part of grades, the separation strength of leaves and stems of tobacco leaves of a part of grades is too low, so that the tobacco leaves are insufficiently separated, the next-stage threshing is carried out, and multiple threshing causes energy waste and breakage, so that the economy is influenced; the separation strength of the other part of the grade tobacco leaves and stems is too high, so that the breakage is generated, and the economical efficiency is influenced. Similar problems also exist in other procedures such as leaf moistening and redrying.
At present, the formula threshing is only to assemble the same or adjacent grades of adjacent production areas of the same year and the same province into a leaf group formula according to the actual conditions of sensory evaluation results and annual allocation amount, the formula of the group of the cross-year and cross-province cannot be realized, the compatibility and the scale of a module are further increased, the style characteristics of raw materials of all grades are revealed, the value of each piece of tobacco leaf is difficult to be fully reflected, and the requirement of industrial cigarette products on the raw materials cannot be met to the maximum extent.
The existing researches all consider that the quality difference of different positions of the same tobacco leaf is obvious, and the quality difference of the tobacco leaf in the same producing area, position and grade is also obvious. But at the same time also: the tobacco leaves with different producing areas, parts and grades have areas with similar quality, and the tobacco leaves with similar quality can form the tobacco leaves with similar size after the tobacco leaves and stems are separated. Therefore, the single-grade tobacco leaves are classified according to the size of the tobacco flakes after the leaves and the stems are separated, and the single-grade tobacco leaves are classified according to the inherent quality of the tobacco flakes essentially, and then are subjected to formula design according to the obtained tobacco flakes with different inherent qualities.

As shown in fig. 1, a formula threshing method based on different specifications of tobacco flakes comprises the following steps:
s1: classifying the raw tobacco according to grades, analyzing the physical characteristics of the tobacco leaves of each grade, setting processing parameters for vacuum moisture regain, leaf moistening and leaf and stem separation of the raw tobacco of each single grade according to the analysis result, and further performing vacuum moisture regain, leaf moistening and leaf and stem separation of the raw tobacco of each single grade;

s4: under the same smoking style, the formula proportion is designed according to the classification condition of the tobacco flakes, and the tobacco flakes are mixed according to the formula proportion and then redried.
Specifically, the existing formulation design concept is based on the quality difference of tobacco leaves in different producing areas, parts and grades, and performs formulation design through the complementarity of the difference, and a basic premise of the concept is that the quality difference of the tobacco leaves in the same producing area, part and grade is very small; however, as described above, in the conventional studies, the quality difference of the same tobacco leaf at different positions is considered to be significant, and therefore the quality difference of the tobacco leaf at the same place of origin, position and grade is also considered to be significant. But at the same time also: the tobacco leaves with similar quality exist in the single tobacco leaves with different producing areas, parts and grades, and the tobacco leaves with similar quality of the same type can form the tobacco leaves with similar size after the tobacco leaves are separated from stems. Therefore, the single-grade tobacco leaves are classified according to the size of the tobacco flakes after the leaves and the stems are separated, and the single-grade tobacco leaves are classified according to the inherent quality of the tobacco flakes essentially, and then are subjected to formula design according to the obtained tobacco flakes with different inherent qualities. The single-grade tobacco leaves are adopted for formula threshing, so that the quality characteristics of each part of each tobacco leaf can be fully utilized, and the quality of each type of tobacco leaf is determined before mixing, so that the actual formula proportion can be executed strictly according to the formula design proportion. In addition, when the mixing operation is carried out, the particle size of the tobacco flakes is relatively small, so that the tobacco flakes are not easy to wind like whole tobacco leaves, and are easy to mix uniformly. Therefore, by adopting the formula threshing method of the single-grade tobacco, the utilization efficiency of the tobacco leaves can be better improved in the threshing and redrying stage, each part of each piece of tobacco leaves can be reasonably used, the proportioning precision of the formula and the control capability of the threshing and redrying process are improved, and the production organization difficulty of the conventional threshing and redrying is further reduced.

(2) Adopting a single-grade feeding mode during threshing and redrying; preprocessing the classified single-grade tobacco leaves in the step (1), wherein the needed preprocessing is as follows: selecting unsuitable tobacco leaves and impurities such as green tobacco, moldy tobacco and the like. Compared with the traditional preparation work before feeding, the pretreatment mode only needs simple leaf selection treatment, has lower requirement on leaf selection site, does not need larger warehouse storage for the selected tobacco leaves, does not need chemical component detection, slitting and other equipment in the leaf selection process, and has the number of leaf selection between 50 and 100, thereby greatly simplifying the feeding preparation process. (3) Feeding and carrying out leaf-stalk separation. The existing production mode is still used from feeding to leaf-stem separation, namely, pretreatment is carried out through the procedures of turning over boxes for feeding, screening sand, moistening leaves, separating leaves and stems and the like, single-grade tobacco leaves are processed in the pretreatment process, the physical characteristics of the single-grade tobacco leaves are approximate, production can be carried out according to the optimal control parameters of the grade tobacco leaves, and therefore the problem of high control difficulty in the production process is solved.
