Technical Field

The invention belongs to the technical field of tobacco process quality evaluation, and particularly relates to a method for judging and evaluating the overall comprehensive quality of cigarette cut tobacco production.

Background

In the three processes of cigarette making, cigarette rolling and packaging, the quality of the cut tobacco after cigarette making affects the subsequent rolling and packaging process and also affects the internal quality of cigarette products. In order to produce the cut tobacco with excellent internal quality, the overall comprehensive quality of the cut tobacco after the cut tobacco processing needs to be inspected and evaluated in a normative, scientific and comprehensive manner. Further improving the overall comprehensive quality of the cut tobacco, and providing technical support and judgment basis for comprehensive evaluation, scientific diagnosis and optimized production of process quality.

A method for constructing a cigarette shred making quality evaluation model based on an analytic hierarchy process (publication number: CN107563672A) comprises the steps of forming an evaluation index system consisting of a target layer, a criterion layer and an index layer, calculating the weight of each evaluation index by adopting a judgment matrix of the analytic hierarchy process, and finally performing comprehensive evaluation on the shred making quality by utilizing a statistical weighting method. The invention establishes an evaluation model based on hierarchical analysis, performs a summary evaluation on each process index in the production process, but does not perform overall evaluation and inspection judgment on tobacco physical indexes and comprehensive indexes, and does not bring tobacco quality inspection of batch population into a judgment and evaluation method.

The invention discloses a cigarette process quality comprehensive evaluation system and method based on grey correlation analysis (publication number: CN101414183A), which is a combination of single process quality evaluation and grey correlation analysis. Firstly, the process capability index of each process parameter is calculated, then, the comprehensive evaluation is carried out by using a grey correlation method, and the rank of the process quality of each evaluation object is obtained. The invention comprehensively judges the process indexes, further evaluates the overall process quality, does not contain physical indexes and overall batch inspection indexes, and only performs the process evaluation by the summary evaluation and ranking of a single process, so that the physical indexes of the tobacco shreds and the comprehensive indexes of each batch cannot be fused.

Compared with other inventions, the invention standardizes the comprehensive quality inspection of various indexes of the cut tobacco after the cut tobacco is processed by making the cut tobacco and the judgment standard of the overall quality of batches. The method is not limited to process indexes, and physical index level of the processed tobacco shreds and comprehensive indexes of batch population are considered. The evaluation integrates all the inspection indexes, determines the subdivision degree of the standard value grade of the evaluation according to the importance of all the indexes, and comprehensively evaluates the overall process quality by combining the comprehensive quality inspection, the flavoring and feeding precision, the blending precision and the like of the cut tobacco, the cut stems and the expanded cut tobacco from thin to total. The comprehensive quality of the cut tobacco is controlled more comprehensively and comprehensively, and the standard management of cut tobacco production and the improvement of the quality of cut tobacco are facilitated.

Specific scoring criteria are shown in the following table:

and (4) comprehensive quality inspection and judgment, wherein the comprehensive quality inspection judges superior products, qualified products and unqualified products according to the comprehensive scores of the flavored cut tobaccos, cut stems and expanded cut tobaccos. The comprehensive quality level is a superior product if the fraction distribution range is more than or equal to 90, the comprehensive quality level is a qualified product if the fraction distribution range is 70-90, and the comprehensive quality level is an unqualified product if the fraction distribution range is less than or equal to 70. And the comprehensive quality level judgment result is used as the basis of batch quality release.

The batch process quality overall judgment and evaluation, wherein when the batch process of the feeding and perfuming precision and the blending precision is judged to reach the standard, the batch process quality overall evaluation is judged to be qualified when the comprehensive quality batch is judged to be qualified; and judging the product to be unqualified when any one of the three is unqualified or unqualified. And taking the overall evaluation result of the batch process quality as the basis of the release of the batch quality.

The system generates a comprehensive silk quality inspection report, and the detailed condition can be checked for technical personnel to analyze and manage.

The technical scheme has the advantages that:

the invention fuses all the process indexes and physical indexes, determines the subdivision degree of the standard value grade of judgment according to the importance of all the indexes, and combines the comprehensive quality inspection and precision with the batch overall process quality from detail to total. The invention has comprehensiveness and comprehensiveness, and is beneficial to quality tracing and standard management of the overall comprehensive quality of the silk production.
