Embodiment Construction

[0017] 1. Experimental materials

[0018] Papermaking method reconstituted tobacco leaf products, sheet base, and coating solution (prepared according to conventional production formula).

[0019] 2 Experimental Instruments

[0020] BUCHI cable extractor, BINDER WTC constant temperature and humidity box, Mettler Toledo AG204 electronic balance, QS-I shredding machine, electric blast drying oven, and silica gel dryer are purchased in the market.

[0021] 3 Sample preparation

[0022] Cut the reconstituted tobacco leaves and base samples by the papermaking method into shreds with a width of 0.85mm, and place them in a constant temperature and humidity box for 48 hours to balance. The temperature of the constant temperature and humidity box is set at 22°C and the humidity is 60%.

[0023] 4. Determination of spreading rate

[0024] Weigh a certain amount of reconstituted tobacco shredded tobacco sample m 1 Place in the solvent cup of the Soxhlet extractor, add distilled water...

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

Technical field: [0001] The invention relates to a method for measuring the coating rate of finished reconstituted tobacco leaves by a papermaking method, and belongs to the technical field of reconstituted tobacco leaves. Background technique: [0002] Paper-making reconstituted tobacco is an important cigarette material. Adding appropriate amount of reconstituted tobacco into the cigarette material can save tobacco material, reduce the cost of cigarettes, and improve the physical properties of cigarettes, reducing harm and tar. With the continuous deepening of the harm reduction and tar reduction projects in the tobacco industry, papermaking reconstituted tobacco leaves will be applied to cigarette formulations on a large scale. [0003] Paper-Process Reconstituted Tobacco (RT for short) is made from tobacco by-products and waste (tobacco stems, chips and shreds, etc.), using improved papermaking technology combined with modern extraction and separation technology. A toba...
