Method for accurately determining thickness of tobacco leaf sample

Abstract

The invention discloses a method for accurately determining thickness of tobacco leaf sample, which is characterized by measuring thickness of tobacco leaf by means of determining volume of a certain area of tobacco leaf. The method comprises the following specific steps of: A, punching hole on a tobacco leaf sample for sampling, and calculating the punched acreage; B, processing the sample; C, determining volume of the sample by drainage; D, calculating thickness of the tobacco leaf. The method provided by the invention overcomes error interference on determination of single sample caused by manual operation; compared with the existing determination method, the method has the following advantages: (1) sampling range is wide, and representativeness is strong; (2) the obtained sample is processed integrally, volume of the sample is determined, error caused by single determination is reduced, and accuracy is higher; (3) operation process of the method is easy to control, result stability is high, and repeatability is excellent.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf appearance quality, and mainly relates to a method for measuring the thickness of tobacco leaves, in particular to a method for measuring the thickness of tobacco leaves by measuring the volume occupied by a certain area of ​​tobacco leaves. Background technique [0002] In the national standard GB2635 of flue-cured tobacco, the thickness of tobacco leaves is expressed by the appearance quality of tobacco leaves. The thickness of tobacco leaves at different insertion sites is different. Generally speaking, the thickness of leaves increases gradually according to the insertion site of tobacco leaves from bottom to top. The thickness of the tobacco leaves is also different. Tobacco leaves with moderate thickness are of high quality, while tobacco leaves that are too thin and thick are of low quality. [0003] At present, the method of measuring the thickness of tobacco leaves generally uses a ...

AI Technical Summary

Problems solved by technology

[0003] At present, the method of measuring the thickness of tobacco leaves is generally measured by a thickness gauge. The main process is to use the thickness gauge probe to give a certain pressure to the sample measurement point, and then to read the data through the sensing of the probe contact point. In the actual operation process, it is found that the measurement process is affected by human operation. The effect of the test is relatively large, the operation is slightly deviated, the result data before and after the difference is very large, the operation stability is very poor, the representativeness of the result is not strong, and the pressure given by the probe is not easy to control, the tobacco leaf is not a hard object, under different pressures Its thickness changes, and the measurement result cannot accurately reflect the thickness of the tobacco leaf, and the accuracy of the result is not great
