Embodiment 1

[0023] Sample collection: The sampling origins are Dali in Yunnan, Chuxiong in Yunnan, Yuxi in Yunnan, Qujing in Yunnan and Zhaotong in Yunnan. The sampling parts are the lower part, the middle part and the upper part, each part is 5 kg, and the varieties are the main local flue-cured tobacco varieties.

[0024] Sample production: The evaluation team composed of tobacco leaf rating experts selects the samples for many times through sensory analysis technology, and finally determines the exact part of the collected samples to improve the accuracy of the results. 20 tobacco leaves were randomly selected from each part of each production area and numbered.

[0025] Three measurement points were randomly selected at the flat middle part of the front of the tobacco leaf, and the average height Sa and kurtosis Sku of the sample were measured with a laser scanning confocal microscope, converted into the roughness characteristic index Sa / Sku, and the average value was taken as the roug...

Embodiment 2

[0032] Collection of primary flue-cured tobacco samples: The origin of the collection is Yuxi, Yunnan, and the small parts sampled are the lower leaves of the lower second shed, the lower second shed leaves, the middle lower leaves, the waist leaves, the middle upper leaves, the upper second shed leaves, and the parietal leaves. Each small part is 2 kg, and the variety is the main local flue-cured tobacco variety.

[0033] Sample making: An evaluation team composed of tobacco leaf grading experts screened the samples through sensory analysis technology, and finally determined the small parts of the samples to improve the accuracy of the results. 20 tobacco leaves were randomly selected from each small part and numbered.

[0034] Three measurement points were randomly selected at the flat middle part of the front of the tobacco leaf, and the average height Sa and kurtosis Sku of the sample were measured with a laser scanning confocal microscope, converted into the roughness cha...

Abstract

The invention relates to a method for judging parts of primary flue-cured tobacco based on laser scanning confocal technology, and belongs to the technical field of tobacco leaf rating. The invention includes the following steps: 1) establishing a judgment model between roughness characteristic index and primary flue-cured tobacco parts; 2) detecting the initial stage to be judged For the average height Sa and kurtosis Sku of the micro-topography of flue-cured tobacco leaves, the ratio of the average height to kurtosis Sa / Sku is used as the roughness characteristic index, and the roughness characteristic index Sa / Sku is substituted into step 1) to determine the part of the tobacco leaf; The laser scanning confocal microscope directly measures the characteristics of tobacco leaves, reducing the complexity of detection and calculation, and can realize the judgment of the upper, middle and lower parts of tobacco leaves, and has a good prospect in the application of intelligent sorting of tobacco leaves .

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf rating, and in particular relates to a method for determining the position of primary flue-cured tobacco based on laser scanning confocal technology. Background technique [0002] my country's flue-cured tobacco standard divides the parts into upper, middle and lower parts. In industrial use, the chemical composition content of tobacco leaves in different parts is different, which leads to different internal quality of different parts and different use values ​​in cigarette formulations. Tobacco leaf part is the first grouping factor of flue-cured tobacco grading standard, and distinguishing part is the premise of distinguishing grade. [0003] In my country's current national standard for flue-cured tobacco, qualitative description is used for the judgment method of flue-cured tobacco parts, and there is a lack of quantitative description of part characteristics. During operation, technicia...
