Embodiment 1

[0050] A comprehensive evaluation method for cut tobacco quality based on principal component analysis, including

[0051] S1, sampling

[0052] S1.1, Cut tobacco sampling

[0053] Randomly select 5 batches of shredded tobacco, and randomly sample 6 times for each batch, and use a sampling container to pick up shredded tobacco at the outlet of the blending and flavoring machine. The sampling time interval is 15±5min;

[0054] S1.2, Sampling of finished cigarettes

[0055] In the form of a fixed sampling machine and fixed sampling personnel, the finished cigarettes are sampled at the outlet of the cigarette machine corresponding to the 5 batches of cut tobacco sampling. Each group of samples is randomly selected 150 cigarettes each time, and the time interval is 30±5min. Continuous sampling 6 times, put in a constant temperature and humidity box [(20±1)℃, RH(60±2)%] to balance for 24 hours, seal and label, and keep the sample for later use;

[0056] S2, data detection

[0...

Embodiment 2

[0085] Carry out sampling, data detection and data standardization processing based on embodiment 1;

[0086] Using SPSS software for Pearson correlation analysis;

[0087] The 11 indicators of the quality of cut tobacco in each test batch are recorded as: filament X 1 , Zhongsi X 2 , short silk X 3 , Shredded X 4 , length X 5 , quality X 6 , circumference X 7 , suction resistance X 8 , hardness X 9 , End wire drawing X 10 , Containing rate X 11 .

[0088] Pearson correlation analysis results:

[0089] Long silk, medium silk and short silk are significantly correlated at the level of 0.01 (P<0.01), and are significantly correlated with broken silk and hardness at the level of 0.05 (P<0.05); medium silk and cigarette length and hardness are significantly negatively correlated (P<0.05), which is significantly correlated with hardness at 0.01 level (P<0.01); short filament is significantly correlated with tip content (P<0.05); quality is significantly correlated with ...

Embodiment 3

[0114] Verification experiment

[0115] The quality of each batch of shredded tobacco was counted, and the standard deviation of the physical index length, mass, circumference, draw resistance and hardness of the cigarette was calculated, and the SPSS software was used to conduct a single-factor analysis of variance. The results are shown in Table 4:

[0116] Table 4 Analysis results of 5 batches of tobacco rolling physical indicators software

[0117]

[0118] It can be seen from the above table that there is no significant difference among batches of standard deviation of length, standard deviation of mass and standard deviation of suction resistance. The standard deviation of circumference and hardness is the lowest in test IV batch, followed by test III, and the highest in test V batch. .

[0119] In order to more accurately evaluate the applicability of each batch of shredded tobacco to the locomotive during rolling, and to rank and score the length, quality, circumfe...

Abstract

The invention discloses a tobacco shred quality comprehensive evaluation method based on principal component analysis method. The principal component analysis method is adopted to comprehensively evaluate a tobacco shred structure and cigarette physical indexes, a new tobacco shred quality comprehensive evaluation system model of an aroma mixing process is established, and the model is verified through rolling quality standard deviation analysis and sensory evaluation. Results show that results of the tobacco shred quality comprehensive evaluation model and a smoking verification experiment based on the method are test III, test IV, test I, test II and test V, and a rolling quality result is that the deviation of batches of the test III and the test IV is relatively low and is consistent with a model evaluation result. Thus, the tobacco shred quality comprehensive evaluation model and evaluation method constructed by the application are simple and visual, are suitable for the production status of the current stage of tobacco shred processing, and can provide a new idea for tobacco shred quality evaluation in the tobacco shred production process.

Description

technical field [0001] The invention relates to the field of shredded tobacco, in particular to a method for comprehensive evaluation of shredded tobacco quality based on principal component analysis. Background technique [0002] The core of cigarette production is to use advanced automation equipment to process re-cured tobacco leaves through a series of processes such as "steaming, adding, cutting, drying, and blending" to produce shredded tobacco that meets the requirements of the silk-making process, and then roll it into qualified tobacco in the wrapping workshop. cigarettes. The blending and flavoring process is an important process and the last process in the cut tobacco production process. The stability and uniformity of cut tobacco quality directly affect the internal quality of subsequent cigarettes and the rolling quality of cut tobacco. [0003] At present, the evaluation of the quality of cut tobacco is based on the evaluation and optimization of the cutting p...
