The method includes the following steps: building a standard curve of a testing proportion and a set proportion; performing floating separation of sampling shredded tobacco at two sampling points of a perfuming roller outlet and a wrapping machine; and calculating the actual proportion and the average proportion of the sampling shredded tobacco at the two sampling points respectively as per the standard curve, so as to obtain the utilization ratio of the tobacco reconstituted through the rolling process. The invention provides the practicable testing method for accurately and objectively evaluating the utilization ratio of the tobacco reconstituted through the rolling process, reliable technical parameters and testing data are provided, and the method is significant in the control of the manufacturing process stability, formula matching and cigarette quality index.
Description
Technical field
The present invention relates to a kind of assay method of reconstituted tobacco utilization factor, particularly relate to a kind of assay method of tobacco leaf reproduced by means of rolling utilization factor.
Background technology
Tobacco leaf reproduced by means of rolling is simple with its equipment, energy consumption is low, cost is low, by the most domestic cigarette enterprise, adopted, but its production reproduce pipe tobacco because tensile strength is little, poor water resistance, the low effective rate of utilization that makes of filling capacity be low, affected anastomose property and the constant product quality of cigarette composition; Simultaneously, the accordance of the stability of tobacco leaf reproduced by means of rolling mixed ratio example and formula rate is also the important indicator of evaluating cigarette production technology process capability.Current common way has three kinds: hand picking method, unit consumption ratioing technigue, filling ratioing technigue, these methods have that workload is large, the shortcoming such as poor accuracy as a result, and can't judge in pipe tobacco, whether each component also meets the formula of design in small unit, more can't judge whether pipe tobacco is evenly distributed in solid space.Therefore, set up in the Accurate Determining cigarette shreds tobacco leaf reproduced by means of rolling mixed ratio example and trans-utilization rate thereof very important meaning is arranged.
Summary of the invention
The present invention provides a kind of in order to overcome above technical barrier just can accurately, objectively measure the method for tobacco leaf reproduced by means of rolling utilization factor.
Purpose of the present invention can realize by following technical proposals:

* 100%.
In formula: R: be the tobacco leaf reproduced by means of rolling utilization factor,
: mix and join rear tobacco leaf reproduced by means of rolling average proportions,
: tobacco leaf reproduced by means of rolling average proportions in cigarette.
In the present invention, the method that other component of described reconstituted tobacco and pipe tobacco is separated is, tobacco mixture is put into to the triacetyl glycerine solvent, utilizes floating partition method, standing separation, and lower floor is reconstituted tobacco, upper strata is other component of pipe tobacco.
Simultaneously, the invention discloses artificial pipe blend amount and sampling pipe tobacco amount is at least 5g, and will guarantee the consistance of artificial pipe blend amount and sampling pipe tobacco amount during sampling.
The present invention also discloses artificial pipe blend amount simultaneously and sampling pipe tobacco amount is 5～10g.Also will guarantee the consistance of artificial pipe blend amount and sampling pipe tobacco amount, artificial pipe blend amount and sampling pipe tobacco amount will approach as far as possible simultaneously.According to general data statistics general knowledge, because sampling amount increases, its data are abundanter, and the accuracy of detection is also higher, so the present invention discloses the sampling scope of 5～10g especially, thereby can guarantee to detect accuracy and the testing cost of data simultaneously.
The invention also discloses described oven dry for drying 30 minutes in the temperature conditions of 80～95 ℃.
Described volatile organic solvent refers to the volatile organic solvent (as ethanol) in chemical field in the present invention, in practical application of the present invention, can specifically select in conjunction with low toxicity, requirement cheaply.
The invention has the beneficial effects as follows: solved current cigarette enterprise tobacco leaf reproduced by means of rolling utilization factor and detected a difficult problem, for accurate, objective detection tobacco leaf reproduced by means of rolling utilization factor provide a kind of feasible method, reliable technical parameter is provided and has detected data, all significant for production control process stability, formula anastomose property and cigarette quality index.
