Method for improving tobacco-drying process capability

Abstract

The invention relates to a method for improving the tobacco-drying process capability. The method comprises the following steps of: acquiring raw data of a plurality of process parameters of a tobacco-drying process; according to the raw data, calculating the process capability index of all process parameters respectively; according to a preset process capability evaluation function, converting the process capability indexes to obtain process capability evaluation values; performing weighted average of the obtained process capability evaluation values to obtain the batch process capability evaluation value of the current batch; and judging whether the batch process capability evaluation value reaches the preset threshold value, if the batch process capability evaluation value does not reach the preset threshold value, checking whether the process capability evaluation values of all process parameters of the current batch reach the preset threshold value and performing optimal operation of the process parameters, of which the process capability evaluation values do not reach the preset threshold value. In the method, the batch process capability evaluation value of the current batch is obtained by calculating the dispersibility of the characteristic values of all process parameters of the tobacco-drying process to determine the batch having problems, and the process parameters having defects are traced, so that a solid foundation is provided for technicians to adjust and optimize the tobacco-drying process.

Description

technical field [0001] The invention relates to the drying technology of tobacco shredded shredded leaves, in particular to a method for improving the process capability of the shredded shredded drying process. Background technique [0002] In the process of cigarette processing and silk making, the silk drying process is the core process of the silk making process, and its treatment effect directly affects the quality of cigarette products. Therefore, stabilizing the parameters of the silk drying process, meeting the design requirements of the silk drying process, and improving the ability of the silk drying process are beneficial to the improvement of the quality of cigarettes. The quality and stability of cigarette products are of great significance. [0003] The current evaluation of the silk drying effect is based on the conformity of the leaf shreds exported from the silk drying machine by sampling inspection, and the parameters of the silk drying process are optimized...

AI Technical Summary

Problems solved by technology

Since the existing optimization of process parameters is based on the results of sampling and testing the outlet shreds in the drying process, and the result is the comprehensive effect of multiple process parameters in the drying process, the pass rate of the sample test results cannot fully reflect The control effect of each process parameter in the silk drying process in the whole production process requires technical personnel with rich experience to find out the specific reasons and give corresponding solutions to optimize the process control. For technical personnel with less experience , it is obviously very difficult, and it often takes a lot of man-hours to conduct repeated trials to achieve a good optimization effect, which will inevitably increase the labor cost and time cost of the optimization process
