Abstract

A kind of high-volume method for fast measuring of irregular blade area.This measuring method includes four steps, and the first step prepares and selection sample, and second step tests the area and weight of samples taken, and the 3rd step establishes the standard curve of blade area and leaf weight, and the 4th step high-volume tests the batch list grade blade area.The high-volume that the present invention is used for irregular blade area quickly measures.

Description

A kind of high-volume method for fast measuring of irregular blade area
Technical field：
The present invention relates to a kind of high-volume method for fast measuring of irregular blade area.
Background technology：
In tobacco industry production, the piece shape requirement of air exercise leaf redrying enterprise is more and more stringenter；Blade area is the objective of " piece shape " Measure, but this measure is built upon on statistical significance, it is meant that need substantial amounts of blade area data.It is multiple Tobacco material used in roasting enterprise and cigarette enterprise, different from being in place of other live plant blades, tobacco leaf almost all All it is wound around folded state, when measurement must be by every carefully expansion.
In real work, common instrument or method（Blade area instrument, copy paper method, digital pictures analytic approach, electro-optical package method Deng）Relatively accurately it can measure or calculate blade area, be adapted to accurately measure a small amount of material.But since its operation is equal It is excessively cumbersome（The tobacco leaf that every winding folds must be carefully unfolded）, it is time-consuming and laborious.Required measurement material one in real work As it is more, take manpower and the time be huge, and often malfunction（Tester is after " boring " work of prolonged repetition, more More to tend to the not abundant enough of tobacco leaf expansion）.
How quickly and accurately to large batch of irregular piece shape（Including but not limited to tobacco leaf）Area is surveyed Amount, and accurate test data is provided, it is a difficult point in basic scientific research and commercial Application.
The content of the invention：
The object of the present invention is to provide one kind be based on weighted regression method, give can accurately, quickly, the irregular leaf of measure batch A kind of high-volume method for fast measuring of irregular blade area of piece area.
Above-mentioned purpose is realized by following technical scheme：
A kind of high-volume method for fast measuring of irregular blade area, this measuring method include four steps, and the first step prepares and choosing Sample is selected, second step tests the area and weight of samples taken, and the 3rd step establishes the standard curve of blade area and leaf weight, 4th step high-volume tests the batch list grade blade area.
A kind of high-volume method for fast measuring of irregular blade area, the first step prepares and selection sample Product are under the conditions of constant temperature and humidity, by the equilibrium moisture content under single-grade blade balance to be measured to the environment, then to be measured A certain number of representative samples are randomly choosed in material, it is spare.
A kind of high-volume method for fast measuring of irregular blade area, the first step prepares and selection sample Product be under conditions of 24 DEG C of temperature, humidity 60%, by the equilibrium moisture content under single-grade blade balance to be measured to the environment, Then the representative samples of 1 ~ 3Kg are randomly choosed from material to be measured, it is spare.
A kind of high-volume method for fast measuring of irregular blade area, second step test samples taken Area and weight be with the same constant temperature and humidity of the first step under the conditions of, using blade area instrument or copy paper method, measure one by one The area of every leaf；Its corresponding weight is measured using precision balance at the same time, data volume is no less than 300 pairs, records spare.
A kind of high-volume method for fast measuring of irregular blade area, the 3rd step establish blade area Standard curve with leaf weight be according to foregoing measurement data, it is using data processing software that the area for measuring blade is heavy to its Amount does figure, and carries out regression fit, you can obtains standard curve between the two, and provides regression equation：S = F(m) .
A kind of high-volume method for fast measuring of irregular blade area, the 4th step high-volume test should Batch list grade blade area is under same environmental condition, using the precision balance used in second step, by remaining without expansion Blade to be measured measure weight one by one, substitute into the equation of above-mentioned standard curve, you can provide corresponding face one by one by regression equation Product.
Beneficial effect：
1. conventional method needs will be all（What winding folded）Tobacco leaf to be measured is carefully unfolded one by one, is measured using leaf area instrument, or The methods of copy paper method, calculates.And under normal circumstances, tester is increasingly inclined to after " boring " work of prolonged repetition It is not abundant enough in tobacco leaf is unfolded, so that data error is increasing.And the present invention only need to be in early period to a small amount of blade Measured area is unfolded one by one, and establishes standard curve；Mounted blade need not need to be only simply located on balance and survey it by follow-up test Weight simultaneously records, you can completes manual working；Work difficulty and intensity are greatly reduced, the error from personnel's subjectivity is dropped to Minimum, long-term accuracy greatly improves.
Conventional method of the present invention is compared, and eliminates the time of the time, i.e. " expansion blade " of two aspects, and " test surfaces The time of product ", and only need the weight of each blade of simple test, you can extrapolate its area；In speed, efficiency and accurate Property etc., measurement weight ratio measurement area is ripe, much effective.
After the standard curve of the present invention is established, the difficulty of follow-up test work substantially reduces, and speed greatly improves, and also causes In high volume, quickly while also ensure that the test of accuracy is possibly realized.
