Embodiment 1

[0021] Tobacco raw materials are extracted to separate the required soluble chemical components, and the extracted slag is made into a slurry through a refining process, and the concentration of the slurry is adjusted to 5.6%; take 1000g of the slurry, and add 50mL of solvent to the slurry There is a solution of 9.7g ammonium carbonate, stir well to make it evenly mixed; then stand and soak for 40 minutes, let the carbonate penetrate the fiber surface and penetrate into the fiber cell space; under stirring conditions, dissolve 17.6g calcium acetate monohydrate in 60mL The solution was added to the impregnating slurry, fully stirred for 10 minutes to make it evenly mixed; then left to react for 40 minutes, and the reaction temperature was 30°C; then the slurry after standing and reacted was formed into a reconstituted tobacco leaf base sheet by a papermaking machine.

[0022] The amount of calcium carbonate produced in the reconstituted tobacco leaf base sheet was about 10.0 g, ...

Embodiment 2

[0024] Tobacco raw materials are extracted to separate the required soluble chemical components, and the extracted slag is made into a slurry through a refining process, and the concentration of the slurry is adjusted to 12.4%; take 500g of the slurry, and add 60mL of the slag to the slag. There is a solution of 16.4g of potassium carbonate, stir well to make it evenly mixed; then stand and soak for 20 minutes, let the potassium carbonate penetrate the surface of the fiber and penetrate into the space between fiber cells; Add it into the impregnating slurry, stir well for 10 minutes to make it evenly mixed; then stand for reaction for 100 minutes, the reaction temperature is 17° C;

[0025] The amount of calcium carbonate produced in the reconstituted tobacco leaf base sheet is about 11.8g, accounting for 19.0% of the fibers in the reconstituted tobacco leaf base sheet. After determination, the retention rate of calcium carbonate is 59.2%.

Embodiment 3

[0027] Tobacco raw materials are extracted to separate the required soluble chemical components, and the extracted slag is made into a slurry through a refining process, and the concentration of the slurry is adjusted to 21.7%; take 400g of the slurry, and add 100mL of solvent to the slag. There is a solution of 10.0g sodium carbonate, stir well to make it evenly mixed; then stand and soak for 60 minutes, let sodium carbonate penetrate the fiber surface and penetrate into the fiber cell space; under stirring conditions, dissolve 21.8g of calcium nitrate tetrahydrate The solution is added to the impregnation slurry, fully stirred for 10 minutes to make it evenly mixed; then left to react for 120 minutes, the reaction temperature is 35°C; then the slurry after the standing reaction is formed into a reconstituted tobacco leaf base sheet by a papermaking machine.

[0028] The amount of calcium carbonate produced in the reconstituted tobacco leaf base sheet is about 9.2g, accounting...

Abstract

The invention relates to a method for increasing the retention rate of calcium carbonate in paper-process reconstituted tobacco sheets. The purpose of the invention is to solve the problems that: since the prior art directly adds calcium carbonate, the bonding force between the calcium carbonate and tobacco fibers is weak, as a result, loss is severe, the material utilization rate is low, the amount of waste water to be treated is large, and the treatment cost is high. The technical point is that: needed chemical constituents are extracted from tobacco material, residue is ground into pulp after extraction, and the concentration of the pulp is regulated between 3 percent and 25 percent; the solution of soluble carbonate accounting for 4 percent to 40 percent of the weight of dry fibers in the pulp is added into the pulp, and is fully stirred and uniformly mixed, and impregnation is then carried out for 20 to 150 minutes, so that the fibers of the pulp can be impregnated with the soluble carbonate; the solution of soluble calcium salt, the molar mass of which is approximately equal to the molar mass of the soluble carbonate, is added into the impregnated pulp, and is fully stirred and uniformly mixed, static reaction is then carried out for 30 to 180 minutes, and the reaction temperature is controlled at 5 DEG C to 50 DEG C; and after the static reaction, the pulp is made into reconstituted tobacco sheets by papermaking equipment.

Description

technical field [0001] The invention relates to a process for making cigarettes, in particular to a method for improving the retention rate of calcium carbonate in the substrate of reconstituted tobacco leaves by papermaking. Background technique [0002] The current cigarette production is different from the traditional production method. One of its characteristics is to add a certain amount of reconstituted tobacco shredded tobacco into the shredded tobacco to improve the use characteristics and processing performance of cigarettes and reduce waste and pollution. The amount generally can reach 20-30%. Reconstituted tobacco leaves are also called tobacco flakes, reconstituted tobacco leaves, or homogeneous tobacco leaves. The production method of reconstituted tobacco leaves by papermaking method is to use tobacco materials such as tobacco powder, tobacco stems, tobacco leaf fragments, and waste tobacco leaves as the main raw materials, pulverize and refine them into tobac...
