Abstract

The invention relates to a method for determining the spreading rate of paper-process reconstituted tobacco finished products, which belongs to the technical field of reconstituted tobacco. The method includes steps: a, taking a certain quantity of paper-process reconstituted tobacco and a sheet base to be shredded, and the placing the tobacco shreds into a constant-temperature and constant-humidity box with the temperature of 22 DEG C and the humidity of 60% to balance for 48 hours; b, weighing a certain quantity of reconstituted tobacco shred samples m1 to be placed in a solvent cup of a Soxhlet extractor, adding distilled water according to feed to liquid ratio of 1:30, and setting the circulation times of the Soxhlet extractor to be 10 times, and the extracting temperature to be 19-level and the temperature of a condensing circulation pump to be 2 DEG C to extract; c, taking out the samples after extraction is finished, transferring the samples into an aluminum box reaching the constant weight of m0, placing the aluminum box into a drying oven, drying the samples at the temperature of 100+/-1 DEG C so that the constant weight of the aluminum box is m2, realizing the precision of the constant weight to be 0.001g, determining moisture content w of the samples, and extracting the sheet base of the reconstituted tobacco by the same method; and d, calculating the spreading rate according to a formula. The method has the advantages that the method is simple, and is applicable to determining the spreading rate of the paper-process reconstituted tobacco finished products.

Description

A kind of method of measuring papermaking-method reconstituted tobaccos finished product spreading rate

Technical field:

The present invention relates to a kind of method of measuring papermaking-method reconstituted tobaccos finished product spreading rate, belong to the reconstituted tobacco technical field.

Background technology:

Papermaking-method reconstituted tobaccos is a kind of important cigarette material, and an amount of reconstituted tobacco that adds can be saved smoke material, reduce the cigarette cost in cigarette material, can also play the physical property of improving cigarette, the effect of lowering harm and decreasing coking.Along with deepening continuously of tobacco business lowering harm and decreasing coking engineering, papermaking-method reconstituted tobaccos will be applied in the cigarette composition on a large scale.

Papermaking-method reconstituted tobaccos (Paper-Process Reconstituted Tobacco; Be called for short RT); Be to be raw material with tobacco secondary product and discarded object (offal, fragment and broken end etc.), the resource regeneration product that grows tobacco that adopts the paper technology after the improvement and combine that modern extraction and separation technology processes.The reconstituted tobacco spreading rate refers to that reconstituted tobacco sheet base dip-coating thing oven-dry weight accounts for the percent value of reconstituted tobacco oven-dry weight, uses formulae express to be spreading rate=[(finished product over dry quantitatively-sheet base over dry is quantitative)/the finished product over dry is quantitative] * 100%.Coating fluid is the main carrier of reconstituted tobacco soluble component and fragrance component; The height of spreading rate directly influences chemical constitution, physical index, fume indication and the suction quality of reconstituted tobacco, is manufacturing ability one of main indexes the most in the reconstituted tobacco technology.Therefore, research reconstituted tobacco spreading rate has certain meaning to improving the reconstituted tobacco quality.

The spreading rate of papermaking-method reconstituted tobaccos all is to calculate through online production at present, and cigarette enterprise has no idea to know the spreading rate of the product of buying.The research to the assay method of papermaking-method reconstituted tobaccos spreading rate does not both at home and abroad appear in the newspapers.Therefore those skilled in the art seeks the method for better measuring the reconstituted tobacco spreading rate in research.

Summary of the invention:

The object of the present invention is to provide the method for simple, the feasible mensuration papermaking-method reconstituted tobaccos finished product spreading rate of a kind of method.

The present invention utilizes cable-styled extraction process, extracts the water-soluble extractive of papermaking-method reconstituted tobaccos finished product, the hydrosolvent extraction ratio of counting yield, and simulation obtains the spreading rate of product, and through online production analog computation spreading rate.

The method of mensuration papermaking-method reconstituted tobaccos finished product spreading rate of the present invention adopts cable-styled extraction method to measure papermaking-method reconstituted tobaccos finished product spreading rate, and the concrete steps of this method are following:

A. get a certain amount of papermaking-method reconstituted tobaccos and sheet Ji Qiesi, placing temperature is 22 ℃, and humidity is balance 48h in 60% the climatic chamber;

B. take by weighing a certain amount of reconstituted tobacco tobacco sample m ₁Placing Soxhlet extractor solvent cup, is to add distilled water at 1: 30 by solid-liquid ratio, and the extraction apparatus cycle index is set is 10 times, extract temperature is that 19 grades, condensation cycle pump temperature are 2 ℃ and extract;

C. extracting finishes takes out sample, is transferred to constant weight, and m weighs ₀The aluminium box in, put into baking oven, under 1 ℃ of 100 scholar, dry to constant weight, m weighs ₂, be accurate to 0.0001g; The water percentage w of while working sample; With method reconstituted tobacco sheet base is extracted;

D. be calculated as follows sample extraction rate and spreading rate:

$E=\frac{m_1\×(1-w)-(m_2-m_0)}{m_1(1-w)}\×100\%$

S _Extract=E _Sample-E _{The sheet base}

In the formula: E is an extraction ratio, %; S is a spreading rate, %.

Experiment material of the present invention is prepared by conventional factory formula, and experimental apparatus is that market is bought.

The invention has the advantages that: method is simple, is applicable to the spreading rate of reconstituted tobacco finished product working sample.

Embodiment:

1. experiment material

Papermaking-method reconstituted tobaccos product and sheet base, coating fluid (by conventional factory formula preparation).
