example 1

[0043] The actual measurement of example one tobacco leaf softness

[0044] 1. 11 pieces of complete first-cured tobacco leaves as test materials

[0045] 2. The test method is carried out according to the given method and steps of the present invention.

[0046] 3. The test results are shown in Table 1.

[0047] Table 1 Tobacco leaf softness measurement results (unit: mN)

[0048]

example 2

[0049] Example 2: Test of distribution characteristics of softness measurement values ​​of tobacco leaves with different softness

[0050] 1. Preparation of test materials: one batch of mixed tobacco samples containing upper, middle and lower tobacco leaves in Hefeng County of Hubei Province and Wushan County of Chongqing in 2013

[0051] 2. Test purpose and method

[0052] Learn about the correspondence between tobacco leaf softness and tobacco leaf softness measurements.

[0053] The softness of the samples to be tested is judged piece by piece by double-blind method, and the softness value is measured.

[0054] 2.1 Qualitative judgment of the softness (hand feel) of the sample:

[0055] The two batches of samples were divided into upper leaves, middle leaves, and lower leaves according to their parts, and each batch of samples was divided into three groups, a total of six groups; the softness evaluation team composed of 6 appearance rating experts for each group of tobacco ...

[0081] Example 3 Reliability Test of Tobacco Leaf Softness Measurement Value Predicting Tobacco Leaf Softness

[0082] 1. Preparation of test materials: Select 100 pieces of mixed samples from Huidong in Sichuan, Ankang in Shaanxi, Sangzhi in Hunan, Lichuan in Hubei, Zhaotong in Yunnan, and Bijie in Guizhou, remove incomplete leaves, and set aside.

[0083] 2. Test purpose and method

[0084] To verify the reliability of predicting the softness of tobacco leaves by using the softness value and its grade classification method; the test adopts a double-blind method, and two independent research groups conduct softness prediction and softness actual judgment respectively, and then compare the results, and the calculation prediction is accurate Rate.

[0085] 2.1 Determination of softness of test samples

[0086] Measured piece by piece of tobacco leaf according to the method specified in the present invention.

[0087] 2.2 Prediction of softness of test samples

[0088] Carry...

Abstract

The invention discloses a measurement and representation method for softness of tobacco leaves. Water balance is performed on the tobacco leaves to be measured for the first time, the normal water content of the tobacco leaves is restored, and cut small pieces can be prevented from being broken and are kept complete. A cutter with a square cutting edge is adopted for cutting in a leaf-pressing mode so that the uniform size specification of the cut small pieces can be guaranteed, wherein the specification of the square cutting edge is 20 mm*20 mm. Through cutting 6-10 small pieces at symmetrical inter-vein positions on the two sides of each main vein, the average value is measured and calculated, the result can be more approximate to the real value of each whole tobacco leaf, and through removing the small pieces with obvious leaf veins on the surfaces, influences on the measurement result by the leaf veins can be removed. Through flattening, the cut small pieces are unfolded, and interference on the measurement result by curling, twisting and shrinking of the leaves can be avoided. Through secondary water balance, the small pieces reach the same regulated water condition before measurement, and through specifying a slit with the width of 5 mm and measuring softness, in the front transverse direction and longitudinal direction, of all the cut small pieces of the leaves, it is guaranteed that the measurement condition and the measurement mode are uniform. The result calculation method and expression mode achieve quantified expression of qualitative indexes.

Description

technical field [0001] The invention relates to a method for measuring and characterizing the softness of tobacco leaves. Background technique [0002] The existing means to guide the classification of tobacco farmers is to distinguish and classify tobacco leaves by distinguishing the maturity, identity, oil content, chroma, and structure of tobacco leaves. However, this complicated method does not conform to the cognitive characteristics of tobacco farmers. The actual effect of training tobacco farmers is also very unsatisfactory, which eventually leads to tobacco farmers mixing various types of tobacco leaves when sorting tobacco leaves, which cannot meet the requirements of the cigarette industry for grade precision control; therefore, simplify the tobacco leaf classification method in the agricultural link, and build fewer and more intuitive And it is necessary to replace the more complex grading system with an intuitive index system that ordinary people can accurately r...
