The determination method disclosed by the invention has the advantages of simplicity and suitability for determining the ration of the reconstituted tobacco finished product.
Description
Technical field
The present invention is specifically related to the quantitative assay method of a kind of reconstituted tobacco finished product, belongs to the reconstituted tobacco technical field.
Background technology
Reconstituted tobacco is a kind of important cigarette material, adds an amount of reconstituted tobacco in pipe tobacco, can play the effect that improves cigarette physical property, lowering harm and decreasing coking, also can save smoke material simultaneously, reduce the cigarette cost.
Reconstituted tobacco is take tobacco secondary product and discarded object (offal, fragment and broken end etc.) as raw material, and the resource regeneration product that grows tobacco that processes in conjunction with certain manufacturing process.
Reconstituted tobacco quantitatively is one of important indicator of weighing the reconstituted tobacco end product quality, the reconstituted tobacco finished product quantitatively refers to the quality of unit area reconstituted tobacco finished product, with formulae express be: the reconstituted tobacco finished product quantitatively=sample quality/sample area, unit is every square metre of gram.
At present, the quantitative measurement of reconstituted tobacco finished product is carried out with reference to national standard GT/B 451.2-2002, and it is 0.01 m that reconstituted tobacco finished product sheet is accurately cut area
210 in sample, the rear calculation sample of weighing is quantitative.But the reconstituted tobacco finished product form that cigarette enterprise is bought is the small pieces after smashing, and cigarette enterprise can't detect buying product according to standard.Therefore, need research to seek the quantitative method of mensuration reconstituted tobacco finished product that is suitable for the convenient, fast operation of cigarette enterprise.
Have no at present the research of report reconstituted tobacco finished product method for quantitatively determining, in the prior art, also do not have the report of reconstituted tobacco finished product method for quantitatively determining aspect so far.
Summary of the invention
The object of the present invention is to provide a kind of quantitative assay method of reconstituted tobacco finished product that is suitable for Cigarette Industrial Enterprise.
The quantitative assay method of a kind of reconstituted tobacco finished product of the present invention is finished through the following steps: select whole more smooth, without some of the reconstituted tobacco finished product small pieces of damaged, corrugationless as sample, and prune sample broken edge and burr straight, analytical balance accurate weighing sample quality W, the g of unit, obtain the sample digital picture by image capturing system, obtain sample area S, the cm of unit by the image processing and analyzing system
2, calculate the quantitative D of reconstituted tobacco sample, the g/m of unit with reconstituted tobacco sample quality and area again
