Embodiment 1

[0010] Soak 700kg of tobacco stems in hot water at 40°C for 1.5 hours and extract to obtain solid tobacco stems and liquid tobacco stem extracts; the degree of defibration of solid tobacco stems is controlled at 10°SR for the first defibration, and the degree of defibration for the second defibration is controlled at 25°SR , The knocking degree of the tobacco stem fiber entering the finished pulp is 26°SR.

[0011] Add finished pulp tobacco stem fibers to 700kg of tobacco leaf fragments soaked at 30°C for 1.5 hours and extract the defibrated tobacco leaf fragments. The degree of flax defibrillation is controlled at 12°. Tobacco stem fiber and tobacco leaf fragment fiber, in the process point of the headflow pipeline from the stabilizer box to the headbox, add dry soot with a particle size of 1mm-60 mesh through the ash adding device, the proportion is 30% by weight, and the paper machine Copying is made into a fiber sheet substrate, the tobacco stem extract is discarded, the t...

Embodiment 2

[0016] Soak 700kg of tobacco stems in hot water at 70°C for 1 hour and extract to obtain solid tobacco stems and liquid tobacco stem extracts; the degree of first defibration of solid tobacco stems is controlled at 12°SR, and the degree of second defibration is controlled at 13°SR , the degree of percussion of tobacco stem fibers entering the finished pulp is 18°SR.

[0017] 700kg of tobacco leaf fragments were soaked at 60° C. for 0.5 hour and extracted to obtain tobacco leaf fragments and tobacco leaf fragment extract. The degree of knocking of the tobacco leaf fragments into the finished pulp tobacco leaf fragment fibers is 18 ° SR, and the degree of knocking of the fiber is controlled at 16 ° SR. After defibrating, the weight ratio is 4% and added to the obtained tobacco stem fibers and tobacco leaf fragment fibers. Add 5% dry soot with a particle diameter of 1mm-60 mesh in the finished pulp tank, and stir evenly. The fiber sheet substrate is made by paper machine. The t...

Embodiment 3

[0022] 700kg of tobacco stems were soaked in hot water at 60°C for 2.5 hours, and extracted to obtain solid tobacco stems and liquid tobacco stem extracts; the first-time defibrillation and knocking degree of solid tobacco stems was controlled at 15°SR, and the second-time defibration was controlled at 26°SR , the degree of percussion of tobacco stem fibers entering the finished pulp is 30°SR.

[0023] Soak 700kg of tobacco leaf fragments at 40±5°C for 1.5 hours and extract to obtain tobacco leaf fragments and tobacco leaf fragment extracts. The degree of knocking of tobacco leaf fragments into finished pulp is 25°SR, and the degree of defibrillation of wheat straw fiber is controlled at 18°SR. Add 12% by weight of the fiber to the obtained tobacco stem fiber and tobacco leaf fragment fiber, add 10% by weight and dry soot with a particle size of 40 mesh to 80 mesh on the paper machine fourdrinier through the ash adding equipment, Stir well. The fiber sheet substrate is made b...

Abstract

The tobacco stem pulping process for producing tobacco flake in method similar to papermaking includes: soaking tobacco stem in hot water of 40-70 deg.c for 1-2.5 hr to extract and solid-liquid separation to obtain solid tobacco stem and tobacco stem extracting liquid; beating tobacco stem fiber in conventional process with primary beating degree of 10-25 deg SR, secondary beating degree of 13-26 deg SR and final beating degree of 14-30 deg SR. The present invention has improved technological process and indexes and the tobacco flake has raised filling performance and capacity of lowering tar releasing amount of cigarette. The present invention can meet the requirement of industrial production and raise the utilization rate of tobacco flake.

Description

technical field [0001] The invention relates to a method for pulping tobacco stems, in particular to a method for pulping tobacco stems in tobacco sheets produced by adding soot into paper. Background technique [0002] Tobacco flakes are reconstituted tobacco leaves that are recombined and processed from tobacco waste materials such as tobacco dust, tobacco stems, tobacco leaf fragments and some low-grade tobacco leaves during the cigarette processing process. On the one hand, the raw materials of tobacco leaves can be utilized to the greatest extent, and the cost of cigarettes can be saved; on the other hand, tobacco sheets play an important role in reducing the release of cigarette tar and reducing the harm of cigarettes. The production method of existing tobacco sheet mainly contains thick slurry method and papermaking method. Tobacco flakes by the thick slurry method are mixed with tobacco powder and a certain glue phase to make a uniform thick slu...
