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
Technical field
The invention belongs to the physical characteristics determination techniques field of tobacco leaf, relate generally to a kind of assay method of tobacco leaf puncture intensity.Be to utilize matter structure appearance through giving the certain initial velocity of ultrasound guided probe, make ultrasound guided probe pierce through the fixedly puncture force of tobacco sample specifically, i.e. the puncture intensity of tobacco leaf.
Background technology
The tobacco leaf physical characteristics is a kind of direct reaction of himself institutional framework, and it is not only closely related with inherent quality of tobacco leaf, can also embody the tobacco leaf processing characteristics simultaneously, and directly influence cigarette manufacture process, product style, cost and other economic factors.In recent years; Along with improving constantly of cigarette processing technology level; Industry has been carried out number of research projects to the research of tobacco leaf physical characteristics aspect; For the raising of cigarette processing technology level and the control of cigarette product quality provide foundation, improved the processed performance of raw tobacco material, and expanded the research range of tobacco leaf physical characteristics on this basis.
In the cigarette process, the mechanical characteristic of tobacco leaf itself directly influences the anti-processability of tobacco leaf, the anti-fragility etc. of making.As: in beating the leaf process,, need set suitable machined parameters according to the mechanical characteristic of tobacco leaf in order to obtain suitable smoked sheet structure; And the mechanical characteristic of different tobacco leaves there are differences, and puncture intensity is the important indicator of reflection tobacco leaf mechanical characteristic.Present stage, tobacco business was more and more to the concern of tobacco leaf mechanical characteristic, also studied some mechanical characteristic assay methods, but rarely had report about the method for tobacco leaf puncture strength detection.
Matter structure appearance (Textrue Analyser) be property tester again, can make the statement of datumization to the rerum natura notion of sample.In recent years along with the continuous development of food-processing industry; This objectivity of matter structure appearance is strong; The instrument of strong operability has become the research instrument and the research means of lot of domestic and international research institution, is rerum natura (matter structure) the standard detection instrument that food-processing industry is generally acknowledged.But the method for utilizing matter structure appearance to measure tobacco leaf puncture intensity is not also seen relevant report at present both at home and abroad.
Summary of the invention
The object of the invention is directed against above-mentioned prior art situation and the assay method of custom-designed a kind of tobacco leaf puncture intensity just.
The measuring principle of institute of the present invention foundation is: different grades of tobacco has physical behaviors such as different identity (being tobacco leaf thickness, porousness etc.), structure, and the difference of tobacco leaf physical behavior causes the difference of tobacco leaf mechanical property.Based on this, utilize matter structure appearance, through giving ultrasound guided probe certain initial velocity, measure the puncture force that probe pierces through tobacco leaf, i.e. the puncture intensity of tobacco leaf.The mechanical characteristic that helps objective sign tobacco leaf is made broken and anti-processability research etc. for tobacco leaf in the cigarette process data support is provided.
The objective of the invention is to realize: utilize matter structure appearance,, measure the puncture force that this probe pierces through tobacco leaf, be the puncture intensity of tobacco leaf through giving ultrasound guided probe certain initial velocity through following technical scheme; Concrete steps are following:
1. tobacco sample chooses
Choose in working sample that blade is complete, the blade face does not have obvious dust and immaculate tobacco sample as specimen.
2. the water balance of tobacco sample
The tobacco sample of choosing is put into temperature: (20 ± 1) ℃, humidity: balance 48h under the constant-temperature constant-humidity environment condition of (65 ± 5) %.
3. the preparation of sample
At first, keep the long middle part of 10cm tobacco leaf, then tobacco sample is cut into the wide strip of 2cm that is along the master pulse vertical direction, and, forms 10 built-in testing tobacco samples the master pulse excision with the blade tip and the excision of phyllopodium position of the good moisture tobacco sample of balance.
4. specimen is fixing
Guaranteeing that ultrasound guided probe is corresponding consistent with the platform puncture perforate of fixing tobacco sample, and under the prerequisite of probe and the smokeless leaf arteries and veins of engaged test tobacco sample, with testing facing up of tobacco sample, and be fixed on the sample fixed station.
5. the setting of matter structure appearance location parameter
Ultrasound guided probe puncture speed: 0.5mm/s.
Ultrasound guided probe induction force: 5g.
Degree of drawing high on the ultrasound guided probe: 10～20mm.
The mensuration of the intensity that 6. punctures and mensuration expression of results
According to the matter structure instrument parameter of setting in 5., measure the puncture intensity of test tobacco sample respectively, and get the puncture intensity of its mean value as this tobacco sample.
Maximum characteristics of the present invention are: through the mensuration to the research of tobacco leaf mechanical characteristic and tobacco leaf puncture intensity; Expanded the research range of tobacco leaf physical characteristics; The mechanical characteristic that helps objective sign tobacco leaf is made broken and anti-processability research etc. for tobacco leaf in the cigarette process data support is provided.
Embodiment
It is following that the present invention measures instance:
According to above-mentioned concrete steps, the puncture intensity of domestic certain place of production different grades of tobacco sample is measured, measure the result and see table 1.The puncture strength detection result of domestic certain place of production same levels, different water cut rate tobacco leaf sees table 2.
The puncture intensity of table 1 different grades of tobacco
Annotate: C
2L refers to the lemon yellow secondary tobacco leaf in middle part, X
3L refers to the lemon yellow three grades of tobacco leaves in bottom.
The puncture intensity of table 2 different water cut rate tobacco leaf
Annotate: C
3L refers to the lemon yellow three grades of tobacco leaves in middle part.
Can know that through table 1 the puncture strength difference of the identical place of production, different grades of tobacco sample is bigger, from puncture strength criterion deviation (the standard deviation reflection be the difference or the dispersion degree of data sample and mean value.) data, the dispersion degree of determination data is less, reliability is higher.Can be known that by table 2 the puncture strength difference of identical place of production grade, different water cut rate tobacco sample is bigger, from marking inclined to one side data, the reliability of determination data is higher.The assay method of the tobacco leaf puncture intensity of therefore being set forth among the present invention can comparatively objectively be analyzed the puncture intensity of tobacco leaf.
