Embodiment 1

[0024] Prepare 500mL of calcium chloride solution with a calcium ion concentration of 0.2mol / L and transfer it to a gas washing bottle, weigh 25.0g of light calcium carbonate and add it to the washing bottle, stir evenly, and introduce carbon dioxide gas at a flow rate of 5L / Min, under the condition of 25°C, react for 1 hour, suction filter and dry the obtained light calcium carbonate dispersion, and use the dried coated calcium carbonate as filler to prepare reconstituted tobacco leaf base.

[0025] The preparation method of the reconstituted tobacco leaf base is to prepare the slurry with the dry mass ratio of wood pulp fiber, tobacco stem fiber and shredded fiber at 18:48:29, control the degree of beating to 28°SR, and add the mass at the same time as the dry pulp mass 18% of the filler, and adjust the concentration of the slurry to a mass concentration of 3% of the dry pulp, and then make a reconstituted tobacco leaf base, dry the base, and set aside.

Embodiment 2

[0028] Prepare 500mL of calcium lactate solution with a calcium ion concentration of 0.25mol / L and transfer it to the gas washing bottle, weigh 37.5g of heavy calcium carbonate and add it to the gas washing bottle, stir evenly, and introduce carbon dioxide gas, the flow rate of carbon dioxide is 10L / min , reacted for 0.5 h at 45° C., suction-filtered and dried the obtained heavy calcium carbonate dispersion, and used the dried coated calcium carbonate as a filler to prepare a reconstituted tobacco leaf base.

[0029] The preparation method of the reconstituted tobacco leaf base is to prepare a slurry with wood pulp fibers, tobacco stem fibers and shredded fibers at an absolute dry mass ratio of 22: 52: 31, control the degree of beating to 32 ° SR, and add the mass to the absolute dry pulp mass 21% of the filler, and adjust the concentration of the slurry to a mass concentration of 3% of the dry pulp, and then make a reconstituted tobacco leaf base, dry the base, and set aside. ...

Embodiment 3

[0032] Prepare 500mL of calcium formate solution with a calcium ion concentration of 0.22mol / L and transfer it to a gas washing bottle, weigh 44.0g of food-grade light calcium carbonate and add it to the washing bottle, stir evenly, and inject carbon dioxide gas, the flow rate of carbon dioxide is 6L / min, under the condition of 30°C, react for 0.7h, suction filter and dry the obtained light calcium carbonate dispersion, and use the dried coated calcium carbonate as filler to prepare reconstituted tobacco leaf base.

[0033] The preparation method of the reconstituted tobacco leaf base is to prepare the slurry with the dry mass ratio of wood pulp fiber, tobacco stem fiber and shredded fiber at 19:51:30, control the degree of beating to 31°SR, and add the mass at the same time as the dry pulp mass 19% of the filler, and adjust the concentration of the slurry to a mass concentration of 3% of the dry pulp, and then make a reconstituted tobacco leaf base, dry the base, and set asid...

Abstract

The invention relates to a preparation method of a regenerated tobacco filler with a paper-making process and application of the regenerated tobacco filler. The preparation method comprises the following steps: dissolving a dissolvable calcium salt into water; preparing a solution with a calcium ion concentration of 0.2-0.3 mol / L; adding calcium carbonate, wherein the molar ratio of the calcium ions in the dissolvable calcium salt to calcium carbonate is (1:2) to (1:5), and stirring uniformly to obtain a suspension; feeding CO2 into the suspension according to a flow of 5-10 L / min, continuously stirring, and reacting at 25-50 DEG C for 0.5-1 hour; performing suction filtration, and drying the filter residue to obtain coated calcium carbonate; preparing pulp with wood pulp fibers, tobacco stem fibers and debris fibers according to an absolute dry mass ratio of 20:50:30, wherein the beating degree is 30 degrees SR; meanwhile, adding coated calcium carbonate, wherein an addition accounts for 20% of the quality of the absolute dry pulp; blending the pulp until the concentration of the pulp is 3%, then manufacturing the regenerated tobacco base with the pulp, and drying the base for standby application. The preparation method disclosed by the invention has the advantages of being high in efficiency, simple to operate, low in cost, and high in application value.

Description

technical field [0001] The invention belongs to the technical field of paper-making reconstituted tobacco leaves, and in particular relates to a method for improving the calcium carbonate retention rate of paper-making reconstituted tobacco leaves based on calcium carbonate surface coating technology. Background technique [0002] Blending papermaking reconstituted tobacco leaves in cigarettes plays an important role in enhancing the brand value of cigarettes, reducing harm and tar, and product quality and safety. In the production process of reconstituted tobacco leaves by papermaking method, a certain amount of filler is usually added to improve the physical and chemical properties of the product. [0003] Calcium carbonate is the most conventional filler for papermaking reconstituted tobacco. At present, the calcium carbonate added by most enterprises is added in the pulp, but because the particle size of calcium carbonate is far smaller than the diameter of the forming ...
