Problems solved by technology

Furthermore, the main aroma components in the tobacco leaf flakes are all provided by the tobacco leaf fragments. The higher the degree of defibration of the tobacco leaf fragments, the more the components that are beneficial to the flavor of the sheet will be lost, resulting in the smoking quality of the papermaking tobacco leaf flakes. Therefore, the degree of defibration of the traditional papermaking method cannot meet the requirements for the production of tobacco sheets.

Embodiment 1

[0011] 700kg of tobacco leaf fragments were soaked in hot water at 30°C for 1.5 hours, and extracted to obtain solid tobacco leaf fragments and liquid tobacco leaf fragment extracts; the solid tobacco leaf fragments were defibrated with conventional equipment well known in this field, and the degree of disintegration of the fiber into the finished pulp tobacco leaf fragments was 14°SR.

[0012] 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 first-time defibration of solid tobacco stems is controlled at 10°SR, and the degree of second-time defibration is controlled at 25° SR, the beating degree of tobacco stem fibers entering the finished pulp is 26 ° SR, and the beating degree of flax defibrillation is controlled at 12 ° SR. After defibrating, it is 6% by weight and added to the obtained tobacco stem fibers and tobacco leaf fragment fibers. The process point of the headpip...

Embodiment 2

[0017] 700kg of tobacco leaf fragments were soaked in hot water at 60°C for 0.5 hour, and extracted to obtain solid tobacco leaf fragments and liquid tobacco leaf fragment extracts; the solid tobacco leaf fragments were defibrated with conventional equipment well known in this field, and the degree of disintegration of the fiber into the finished pulp tobacco leaf fragments was 18°SR.

[0018] 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. 4% by weight is added to the obtained tobacco stem fiber and tobacco leaf fragment fiber, and 5% by weight of dry soot with a particle size of 1mm-60 mesh is added to the finished pulp tank, and stirred evenly. The fiber sheet substrate is made by paper machine. The tobacco stem extract is discarded, and the tobacco leaf chip extract is concentrated through distillation, and then sprayed onto the shaped substrate, dried, sliced, and shaped.

Embodiment 3

[0023] 700kg of tobacco leaf fragments were soaked in 50°C hot water for 1 hour and extracted to obtain solid tobacco leaf fragments and liquid tobacco leaf fragment extracts; the solid tobacco leaf fragments were defibrated with conventional equipment well known in this field, and the degree of disintegration of the fiber into the finished pulp tobacco leaf fragments was 30°SR.

[0024] Soak 700kg of tobacco stems in hot water at 60±5°C for 1.5 hours and extract to obtain solid tobacco stems and liquid tobacco stem extracts. °SR, the beating degree of tobacco stem fibers entering the finished pulp is 30°SR, and the beating degree of wheat straw defibrating is controlled at 18°SR. After defibrating, the weight ratio is 12% and added to the obtained tobacco stem fibers and tobacco leaf fragment fibers, 10% by weight of dry soot with a particle size of 40 mesh to 80 mesh is added to the fourdrinier wire of the paper machine through the ash adding equipment, and the mixture is ev...

Abstract

The tobacco bits pulping process for producing tobacco flake in method similar to papermaking includes: soaking tobacco bits in hot water of 20-60 deg.c for 0.5-1.5 hr to extract and solid-liquid separation to obtain solid tobacco bits and tobacco bits extracting liquid; beating tobacco bits fiber in conventional process with final beating degree of 14-30 deg SR and preferably 18-25 deg SR. The present invention has improved technological process and indexes and the tobacco flake have 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 pulping method of tobacco leaf fragments, in particular to a pulping method of tobacco leaf fragments produced by adding tobacco ash 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...
