Problems solved by technology

The appearance quality of tobacco leaves is an external reflection of the internal quality. At present, most industrial enterprises sort the appearance quality in accordance with GB 2635, including color, maturity, leaf structure, identity, oil content, chroma, damage and many other factors. The process needs to pay attention to many indicators, and requires a high level of grading for operators; there is currently no quick and accurate method to predict industrial applicability based on the appearance quality of batches of tobacco leaves

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0032] 1) Sampling

[0033] Select a C2F grade in a certain production area as the test sample, and the number of sampling packages is determined according to 0.1% of the total load of the goods (for example, if the large sample is 20,000 loads, the number of sampling packages = 20,000*0.1%, that is, 20 packages are selected for sampling); each package Take 5-7 samples from the center to the surroundings, and take 10-15 tobacco leaves from each place. A total of 14 kg of samples were taken for this test.

[0034] 2) Industrial sorting of sample appearance

[0035] Industrial sorting was carried out on the test samples of C2F grade, and the appearance quality of the test samples was classified...

Abstract

The invention discloses a method for predicting industrial applicability of separated tobacco leaves through appearance characteristic indexes of tobacco leaves. The method comprises the following steps: sampling; preparing an industrial separation sample; measuring and calculating a classified sample ratio and quantizing appearance quality indexes; performing sensory evaluation on industrially separated samples, quantizing the indexes and determining the industrial applicability; establishing tobacco leaf industrial applicability classification and prediction model based on appearance indexes, and determining the appearance characteristic indexes and index values; establishing a fitted curve between the appearance characteristic indexes and corresponding weight ratios thereof; and calculating an industrial applicability quantized predicted value of batches of raw materials according to the appearance characteristic indexes and the fitted curve. The method disclosed by the invention has important significances for guiding industrial separation of tobacco leaf raw material quantization and improving the industrial applicability of the tobacco leaf raw materials.

Description

technical field [0001] The invention relates to a method for determining the appearance feature index of batch-sorted tobacco leaves based on industrial requirements, in particular to a method for predicting the industrial applicability of sorted tobacco leaves through the characteristic appearance index of tobacco leaves, and belongs to the technical field of tobacco leaf quality evaluation. Background technique [0002] The purpose of industrial sorting of tobacco leaves is to refine the quality characteristics of tobacco leaves, make the quality boundaries clearer, and make the quality characteristics more obvious. With the acceleration of the big brands and big markets of tobacco industry enterprises, and guided by the demand for raw materials of industrial enterprises, industrial sorting of tobacco leaves is an inevitable choice to improve the applicability and stability of raw material formulations. The appearance quality of tobacco leaves is an external reflection of ...
