Embodiment 1

[0020] A flexible pulping process for reconstituted tobacco leaves, the method steps are as follows:

[0021] ① Use a high-concentration disc mill to beat the solid material of the extracted tobacco leaf fragments in series. Adjust the concentration to 3.0% in the line pulp storage tank; use two high-consistency disc mills in series to beat the extracted tobacco stem solid material, the flow rate is 500kg / h based on absolute dry pulp, the beating concentration is 15%, and the beating degree is 15°SR , the obtained stalk pulp slurry enters the stalk line pulp storage tank to adjust the concentration to 3.5%; after the wood pulp is crushed, the concentration is adjusted to 3.0%, and a low-consistency double-disc mill is used for beating, with a flow rate of 10m 3 / h, the degree of beating is 15°SR, and the treated wood pulp enters the wood pulp storage tank;

[0022] ② After the leaf pulp, stem pulp and wood pulp after a period of beating treatment in step ① are mixed according...

Embodiment 2

[0026] A flexible pulping process for reconstituted tobacco leaves, the method steps are as follows:

[0027] ①Three sets of high-concentration disk mills are used to beat the solid material of the extracted tobacco leaf fragments in series. Adjust the concentration to 4.5% in the line pulp storage tank; use 4 sets of high-concentration disc mills in series to beat the extracted tobacco stem solid material, the flow rate is 3000kg / h based on absolute dry pulp, the beating concentration is 8%, and the beating degree is 16°SR , the obtained stalk pulp slurry enters the stalk line pulp storage tank to adjust the concentration to 4.0%; after the wood pulp is crushed, the concentration is adjusted to 2.5%, and two low-consistency double-disc mills are used for beating in series, with a flow rate of 30m 3 / h, the degree of beating is 12°SR, and the treated wood pulp enters the wood pulp storage tank;

[0028] ②The leaf pulp, stalk pulp and wood pulp after a period of beating treatm...

Embodiment 3

[0032] A flexible pulping process for reconstituted tobacco leaves, the method steps are as follows:

[0033] ①Use two high-concentration disk mills to beat the solid material of the extracted tobacco leaf fragments in series. Adjust the concentration to 3.5% in the line pulp storage tank; use three high-consistency disc mills in series to beat the extracted tobacco stem solid material, the flow rate is 1500kg / h based on absolute dry pulp, the beating concentration is 20%, and the beating degree is 30°SR , the obtained stalk pulp slurry enters the stalk line pulp storage tank to adjust the concentration to 4.5%; after the wood pulp is crushed, the concentration is adjusted to 3.0%, and a low-consistency disc mill is used for beating, with a flow rate of 5m 3 / h, the degree of beating is 12°SR, and the treated wood pulp enters the wood pulp storage tank;

[0034] ②The leaf pulp, stalk pulp and wood pulp after a period of beating treatment in step ① are sent to the distribution...

Abstract

Disclosed is a flexibility pulping process of reconstituted tobaccos. The process includes the steps that extracted tobacco fragment solid materials are pulped through a high consistency disc refiner, the flow is 300-2000kg/h on the basis of oven dry stock, the pulping concentration is 8-20 percent, the pulping degree is 12-20 degrees SR, and the slurry density of leaf slurry is adjusted to be 3.0-4.5 percent; extracted tobacco stem solid materials are pulped through a high consistency disc refiner, the flow is 300-3000kg/h on the basis of oven dry stock, the pulping concentration is 8-20 percent, the pulping degree is 15-30 degrees SR, and the slurry density of stem slurry is adjusted to be 3.0-4.5 percent; mixed slurry after two-stage pulping treatment is conveyed to a reconstituted tobacco production technology for manufacturing paper with pulp and for producing. The flexibility pulping process is applied to the production process of the reconstituted tobaccos in the paper-making method, and the practical problems in the production process can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method. Background technique [0002] Domestic paper-making reconstituted tobacco technology started relatively late, and it has been industrialized for less than ten years. Because it has broad application prospects for reducing consumption in the cigarette industry and improving cigarette quality, it has developed rapidly. At present, the production method of domestic papermaking reconstituted tobacco leaves is to use tobacco leaf fragments, tobacco stems and other non-tobacco fibers produced during cigarette processing as raw materials, undergo solvent extraction, concentrate the extract to make a coating solution, and use the extracted solids to make paper. The process principle of the method is to obtain reconstituted tobacco leaves that can be used by the cigarette industry through the production processes of beating, copying, molding, backcoating...
