As shown in fig. 1, an embodiment of the present application provides a tobacco raw material secondary blending method, which includes the following steps:

s1, obtaining a tobacco raw material formula list.

The tobacco material recipe sheet generally includes grades of tobacco material, weights of tobacco material at each grade, and proportions of the weights of tobacco material at each grade to total weight of tobacco material at all grades. Wherein the grades in the tobacco material typically comprise between twenty and thirty different grades.

Wherein, the following table (table one) is a formula sheet of tobacco raw materials:

watch 1

As shown in table one, the recipe sheet contains 26 tobacco material grades, the total weight of the tobacco material in all grades is 6754.86, the tobacco material in each grade has a certain independent weight, and the ratio of each independent weight to the total weight forms each weight ratio in table one.

And S2, sequencing the tobacco raw material grades in the tobacco raw material formula sheet according to a set sequence. Therefore, the recipe can be conveniently split.

Wherein, step S2 specifically includes:

and S21, acquiring the weight ratio of the tobacco raw materials under each grade in the tobacco raw material formula list in all the tobacco raw materials.

And S22, sorting the tobacco raw material grades in the tobacco raw material formula sheet in the order from small to large according to the weight ratio.

Wherein, the following table (table two) is a formula list obtained by sequencing the formula list shown in the table one:

watch two

As shown in Table II, the weight ratios of the tobacco materials were arranged in descending order.

And S3, acquiring the maximum value and the minimum value of all weight ratios.

As shown in Table II, the maximum weight ratio was 16.67%, and the minimum weight ratio was 0.17%.

And S4, determining a splitting coefficient according to the ratio of the maximum value to the minimum value.

As shown in Table two, the recipe sheet was disassembledHas a division coefficient of

And S5, splitting the tobacco raw material formula list into a set number of sub-formula lists according to the splitting coefficient.

Specifically, step S5 specifically includes:

s51, judging whether the splitting coefficient is less than or equal to a first set value; if yes, go to step S52; if not, the process proceeds to step S53.

Wherein, the first set value may be 10.

And step S52, not detaching the distribution square list.

If the splitting coefficient is less than or equal to 10, the weight of the tobacco raw materials of each grade is relatively uniform, the formula sheet does not need to be split in a preparation workshop, and only the leaf paving design needs to be carried out according to the formula of the formula sheet. However, this is almost nonexistent during the secondary compounding process.

Step S53, judging whether the splitting coefficient is larger than a first set value and smaller than or equal to a second set value; if yes, go to step S54; if not, the process proceeds to step S55.

Wherein, the second set value may be 100. That is to say, when the splitting coefficient is between 10 and 100, it indicates that the weight ratio difference between the raw materials of each grade is large, and if the leaves are directly paved according to the recipe list, the mixture of the paved leaves is not uniform, therefore, in this embodiment, the original recipe list can be split, so that the splitting coefficient of each split recipe list is reduced to a value close to the first set value.

And S54, splitting the formula list into two sub-formula lists.

The two sub-formula lists can be used as independent formulas for leaf paving respectively, and two feeding modules can be obtained after leaf paving is carried out according to the two sub-formula lists.

As shown in the following tables (table three and table four), the sub-recipe list shown in table three is the first sub-recipe list after the recipe list shown in table two is split, and the sub-recipe list shown in table four is the second sub-recipe list after the recipe list shown in table two is split.

Step S55, judging whether the splitting coefficient is larger than a second set value; if so, the process proceeds to step S56.

In this embodiment, if the splitting coefficient is greater than 100, it indicates that the weight difference between the tobacco raw materials of each grade in the recipe list is significant, and the original recipe list needs to be split into a plurality of sub recipe lists, so as to ensure that the splitting coefficient of each sub recipe list is close to the first set value.

And S56, splitting the recipe list into more than three sub-recipe lists.

And S6, spreading and blending the tobacco raw materials according to the sub-formula list.

It should be noted that the ratio of the total weight of the tobacco raw materials in each split sub-formula sheet is not more than 10, so that the weight of the tobacco raw materials in each sub-formula sheet is close to each other, and after She Hunliao is paved according to the sub-formula sheet, each feeding module with close weight and uniformly mixed tobacco raw materials can be obtained, so that the mixing uniformity of each feeding module can be ensured in the process of mixing each feeding module.

As shown in table three and table four, the total weight of the tobacco materials involved in the first sub-formula sheet shown in table three was 1456.66, the total weight of the tobacco materials involved in the second sub-formula sheet shown in table four was 5298.2, and the ratio of the total weight of the tobacco materials involved in the second sub-formula sheet to the total weight of the tobacco materials involved in the first sub-formula sheet was about 3.6.

Therefore, compared with the prior art, the tobacco raw material secondary blending method provided by the embodiment of the application can ensure the uniformity of tobacco raw material leaf laying blending according to each sub-formula sheet by splitting the tobacco raw material formula into more than two sub-formula sheets.

Specifically, step S6 specifically includes:

and S61, determining the number of the feeding stations occupied by the raw materials under each grade in each sub-formula list according to the total number of the feeding stations.

And S62, spreading tobacco raw materials according to the number of feeding stations occupied by the raw materials under each grade in each sub-formula list.

It should be noted that the number of the feeding stations in the existing preparation workshop generally includes 30 to 80, preferably 48 in this embodiment, six feeding and leaf laying lines may be arranged in parallel in the longitudinal direction, and eight feeding stations are arranged on each feeding and leaf laying line in the feeding direction. According to the quantity of the tobacco raw materials needing to be fed on each feeding station and the quantity of the tobacco raw materials under each grade, only one grade of tobacco raw materials are arranged on each feeding station, and the feeding raw materials with more than two grades on one feeding station can not be generated, so that the uniformity of mixing after feeding can be ensured.

Wherein the tobacco raw materials with different grades in each sub-formula list are respectively laid on each independent feeding station in the direction vertical to the flowing direction of the materials. That is to say, the tobacco raw materials with different grades are respectively paved on the feeding stations at the same position on each feeding leaf paving line as far as possible, so that the uniformity of the material proportion can be ensured.

As shown in the following tables (table five and table six), table five provides data for leaf tiling according to the first sub-recipe and table six provides data for leaf tiling according to the second sub-recipe.
