Embodiment 1

[0034] 1 Materials and methods

[0035] 1.1 Material data

[0036] The data in this study were provided by China Tobacco Guizhou, including the processing quality data of 10 leaf threshing and redrying enterprises in the past three years (2015-2017), and each enterprise was named BF, BS, BJ, CZ, DC, MZ, MT , QXN, SM, YN.

[0037] Select the output rate of the upper-class tobacco module in the middle, the rate of large and medium-sized finished products (>12.7×12.7mm 2 ), finished product large rate (> 25.4×25.4mm 2 ), finished film rate (12.7×12.7-25.4×25.4mm 2 ), finished small piece rate (6.35×6.35-12.7×12.7mm 2 ), finished product fragment rate (2.36×2.36-6.35×6.35mm 2 ), finished product crushing rate (2 ), raw tobacco stem content rate, finished product leaf stem content rate, finished product stem leaf content rate, raw tobacco moisture content, and finished product moisture content, a total of 12 processing indicators were analyzed.

Abstract

The invention relates to a threshing and redrying processing quality comprehensive evaluation method based on multivariate statistics. The threshing and redrying processing quality comprehensive evaluation method comprises the following steps: (1) determining evaluation indexes; (2) factor analysis: carrying out KMO and Bartlett inspection on evaluation index data of threshing and redrying of different batches, and carrying out factor analysis if the inspection is passed; dimensionality reduction is carried out on the evaluation index data, and main factors with lambda larger than 1 are extracted; analyzing the load matrix of each main factor, determining a score model of each main factor, and calculating main factor scores of threshing and redrying of different batches; and (3) clusteringanalysis: carrying out clustering analysis according to the scores of the main factors of threshing and redrying of different batches, and analyzing the change condition of the threshing and redryingprocessing quality of each type according to the clustering condition of the system. The evaluation method provided by the invention is scientific and visual, the threshing and redrying processing quality is effectively judged, and a theoretical support basis is provided for improving the threshing and redrying processing quality and averaging processing; the method is suitable for evaluating andcomparing the threshing and redrying quality between batches.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing quality evaluation, in particular to a comprehensive evaluation method for threshing and redrying processing quality based on multivariate statistics. Background technique [0002] The quality of threshing and rebaking has attracted much attention from rebaking enterprises and industrial enterprises, and its quality directly affects the cost, safety and quality of cigarette raw materials. At present, nicotine CV value is often used to evaluate the quality of threshing and redrying processing, which stipulates that nicotine CV≤3.5% is qualified. Regarding the evaluation method of the quality of threshing and redrying, the predecessors also studied the chemical composition uniformity of threshing and redrying tobacco, the structural stability of tobacco leaves, the uniformity of the appearance and color of finished tobacco, the quality evaluation method, and the quality of redrying.
