Embodiment Construction

[0025] The present invention measures example as follows:

[0026] According to the specific steps above, the puncture strength of different grades of tobacco leaf samples from a domestic production area was measured, and the results are shown in Table 1. The test results of puncture strength of tobacco leaves of the same grade and different moisture content in a domestic production area are shown in Table 2.

[0027] Table 1 Puncture strength of different grades of tobacco leaves

[0028]

[0029] Note: C 2 L refers to the middle lemon yellow second grade tobacco leaf, X 3 L refers to the lower lemon yellow third grade tobacco leaves.

[0030] Table 2 Puncture strength of tobacco leaves with different moisture contents

[0031]

[0032] Note: C 3 L refers to the middle lemon yellow three grade tobacco leaves.

[0033] It can be seen from Table 1 that the puncture strength of tobacco samples from the same place of origin and different grades varies greatly. From th...

Abstract

The invention relates to a method for measuring puncture strength of tobacco. The method is characterized in that: the puncture force of puncturing the tobacco by a probe is measured by using a texture analyzer and giving a certain initial speed to the puncturing probe, wherein the puncture force is the puncture strength of the tobacco. The method particularly comprises the following steps: (1) selecting a tobacco sample; (2) balancing water of the tobacco sample; (3) preparing the sample; (4) fixing the test sample; (5) setting measurement parameters of the texture analyzer; and (6) measuring the puncture strength and representing the measuring result. The method has the biggest characteristics that: according to research on the mechanical property of the tobacco and measurement of the puncture strength of the tobacco, the research range of the physical properties of the tobacco is widened, the mechanical property of the tobacco is objectively represented, and data support is provided for research on crushing and processing resistance of the tobacco in the processing procedure of cigarettes.

Description

[0001] technical field [0002] The invention belongs to the technical field of measuring the physical properties of tobacco leaves, and mainly relates to a method for measuring the puncture strength of tobacco leaves. Specifically, the texture analyzer is used to give the puncture probe a certain initial velocity, so that the puncture probe can penetrate the fixed tobacco leaf sample with the puncture force, that is, the puncture strength of the tobacco leaf. Background technique [0003] The physical characteristics of tobacco leaves are a direct response to its own organizational structure. It is not only closely related to the internal quality of tobacco leaves, but also reflects the processing performance of tobacco leaves, and directly affects the cigarette manufacturing process, product style, cost and other economic factors. In recent years, with the continuous improvement of cigarette processing technology, the industry has carried out a lot of research work on the ...
