Embodiment 1

[0024] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . Gained tobacco stems and tobacco leaf fragment fibers are added with added fiber (8%, weight ratio) after defibration, and dry soot (particle diameter 20 mesh) is added through a designed ash adding device at the headflow pipeline process point from the stabilizer box to the headbox. -60 mesh) is made into a fiber sheet base sheet by paper machine, and the ratio is 20% (weight ratio). The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.

Embodiment 2

[0029] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . The resulting tobacco stems and tobacco leaf fragments are added with defibrated additional fibers (8%, weight ratio), and 30% (weight ratio) of dry soot (particle size 20 mesh-60 mesh) is added to the finished pulp tank and made by paper machine Fiber sheet substrate. The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.

[0030] According to the appearance inspection, the sheet structure is loose and the front surface is uneven.

Embodiment 3

[0034] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in hot water at 60±5°C and 30±5°C for 1.5 hours respectively, extracted, and solid-liquid separation was performed to obtain solid tobacco stems and tobacco leaf fragments, liquid tobacco stem concentrate and tobacco leaf fragment concentrate . Gained tobacco stems and tobacco leaf fragment fibers are added to the added fiber (8%, weight ratio) after the defibration, and are added to the filter net of a paper machine through a special soot adding device at the head box (headbox) to the first section of the paper machine vacuum floating roller. % (weight ratio) dry soot (particle diameter 50-80 mesh) is evenly sprayed on the wet slurry on the net, and is made into a fiber sheet substrate through paper machine. The tobacco stem extract is discarded, and the tobacco chip extract is concentrated by distillation, and then dip-coated on the formed substrate, dried, sliced, and formed.

Abstract

A method for using the fume dust as the filler in the process for preparing tobacco sheet by paper making method features that the fume dust (5-30 Wt%) can be added at 5 technological sites: pulp pool, pipeline between pulp stabilizing tank and pulp flowing tank, long screen, the position between vacuum floating roller and primary pressing, and the coating unit. It can improve the quality of tobacco sheet and low cost.

Description

technical field [0001] The invention relates to a method for adding soot in the process of producing tobacco sheet by papermaking method. 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 material of tobacco leaves can be utilized to the greatest extent, and the cost of cigarettes can be saved. On the other hand, tobacco sheet has played 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 slurry, which is evenly coated on the steel belt a...
