[0002] Leaf threshing and redrying are the first link in cigarette industrial production. The entire processing process adopts assembly line production, and the indicators between each process are highly dependent and restrictive. As a key quality indicator, material flow is mainly affected by the grade of incoming materials and processing. The impact of moisture changes in the process leads to poor matching between the flow rates of each process, large flow fluctuations, and unreasonable flow settings between processes will also affect the fluency of the production process, and ultimately directly affect the quality of the product. stability

Embodiment 2
[0033] Example 2: Let's take the 2018 season VCO3B module tobacco leaves as an example, as figure 2 Shown is the recipe sheet for this module.
[0034] It can be seen from the figure that the proportion of smoke in the upper part of the module is 3.00%, the proportion of smoke in the lower part is 7.56%, and the proportion of smoke in the middle part is 89.45%. In addition, the production rate of different parts of tobacco leaves in the 2018 roasting season is calculated as shown in the table below.
[0035]
[0036]
[0037] According to the proportion of tobacco leaves in different parts of the formula sheet and the production rate of tobacco leaves in different parts, the production rate of VCO3B module tobacco leaves can be calculated as 66.93% according to the calculation formula of the production rate.
[0038] Finally, the average moisture content of the VCO3B module tobacco leaves in the 2018 curing season was 15.45%, 17.29% and 18.37%, respectively.

The invention discloses a method for calculating flow matching between threshing and redrying processes, and belongs to the technical field of tobacco processing quality control, wherein the method for calculating flow matching between threshing and redrying processes comprises the steps: step 1, formula proportions of tobacco leaves at different parts and sheet yields of the tobacco leaves at thedifferent parts are calculated; step 2, a reverse pulling mode is adopted, the standard flow of a baking machine serves as a pulling point, the primary leaf moistening set flow and the secondary leafmoistening set flow are reversely calculated, and the flow stability among all processes is guaranteed; and step 3, calculating the correlation among the primary leaf moistening, the secondary leaf moistening and the leaf baking process flow according to the calculation in the steps 1 and 2. According to the method, the processability of the incoming material grade and the change rule of moisturein the processing process are comprehensively considered, a set of scientific calculation method is formed, the frequency of shutdown material breaking is reduced, and the flow matching performance and stability among all processes are improved.
Description
technical field [0001] The invention belongs to the technical field of tobacco processing quality control, and more specifically relates to a calculation method for flow matching between threshing and redrying processes. Background technique [0002] Leaf threshing and redrying are the first link in cigarette industrial production.
