Problems solved by technology

[0006] Another object of the present invention is to provide the application of the modified tobacco stem fiber in the preparation of reconstituted tobacco leaves by the thick pulp method. The modified tobacco stem fiber not only has good hydrophilicity, but also has better strength and can completely replace the existing plant fiber. Obtain reconstituted tobacco leaves with excellent tensile strength, and can overcome the shortcomings of existing plant fiber burnt products that are highly irritating, have a bad aftertaste after smoking, and are unfavorable to cigarette smoking

Embodiment 1

[0028] Add 10 kg of hot water at 60°C to a certain container, then add 1 kg of citric acid, and stir until it is completely dissolved; add 5 kg of tobacco stems into the container and soak to make the water content reach 50.6%; then use conventional high-concentration disc grinding The tobacco stems are machine ground to obtain cut stems with an average length of about 1.2 mm. Put the shredded stems into another airtight container, pass through high-temperature steam at 140°C, and process for 20 minutes.

[0029] Prepare reconstituted tobacco leaves by thick pulp method with modified tobacco stem fibers: add 190 kg of water into a certain capacity conditioning tank, then add the above-mentioned tobacco stem fibers, and stir evenly; add an equal amount of adhesive and humectant according to the general production requirements, Stir well. The above-mentioned substances are mixed with tobacco leaf powder so that the weight percentage of the modified tobacco stem fiber in the fin...

Abstract

The invention discloses a preparation method and application of modified tobacco stem fibers. The preparation method of the modified tobacco stem fibers includes soaking tobacco stems in a water solution containing butanetetracarboxylic acid, citric acid or polymaleic acid, grinding the soaked tobacco stems into tobacco stem fibers by a disc grinder, and subjecting the obtained tobacco stem fibers to high-temperature steam treatment so as to obtain the modified tobacco stem fibers. The prepared modified tobacco stem fibers are high in strength and good in hydrophility and substitutes for original externally-added plant fibers to be used for preparing reconstituted tobacco by a slurry process, so that the prepared finished reconstituted tobacco is qualified in tensile strength and improved in smoking quality.

Description

technical field [0001] The invention relates to a preparation method and application of modified tobacco stem fibers, belonging to the field of cigarette manufacturing. Background technique [0002] Tobacco leaves consist of leaves and stems, which are the veins of the leaves. In the production of cigarettes, leaves are mainly used, and the treatment of tobacco stems is mainly in the following ways: a small amount of tobacco stems can be cut into shreds and enter the cigarette leaf group formula together with the leaves, a small amount can be used to make reconstituted tobacco leaves, and most of them are used as waste Incinerate or bury. [0003] For the resource utilization of tobacco leaves, there are many researches on the utilization of tobacco stems. Chinese patent 201210062185.X discloses a preparation method of paper base for reconstituted tobacco leaves from tobacco stems. Tobacco stems are used as raw materials to prepare by papermaking method. After the tobacco ...
