Embodiment 1

[0017] Such as figure 1 As shown, a method for regulating the chloride ion of reconstituted tobacco leaves in the present invention is to use ion exchange technology to process the extract of reconstituted tobacco leaves, remove the chloride ions in the extract, and realize the regulation and control of the chloride ion content of reconstituted tobacco leaves. The steps of the method are as follows:

[0018] 1) The extract produced in the extraction section of the reconstituted tobacco leaf production process is separated and purified to remove suspended solids and then stored in a liquid storage tank;

[0019] 2) Pass the purified extract in the liquid storage tank through an anion exchanger according to the proportion of 90% of the total mass for ion exchange to remove chloride ions in the liquid; the anion exchanger uses styrene anion resin and sodium hydroxide to regenerate;

[0020] 3) Adjust the pH value of the extract after anion exchange treatment to 6 with malic acid...

Embodiment 2

[0023] A method for regulating and controlling chlorine ions in reconstituted tobacco leaves, the method steps are as follows:

[0024] 1) Separating and purifying the extract produced in the extraction section of the reconstituted tobacco leaf production process to remove suspended solids;

[0025] 2) Pass 20% of the total mass of the purified extract through an anion exchanger for ion exchange to remove chloride ions in the liquid; the anion exchanger uses styrene anion resin and is regenerated with sodium hydroxide;

[0026] 3) Adjust the pH value of the extract solution after anion exchange treatment to 8 with malic acid;

[0027] 4) Mix 20% of the extracted solution after adjusting the pH value with 80% of the extracted solution that has not undergone ion exchange treatment;

[0028] 5) Concentrate and adjust the mixed extract before entering the coating production to prepare reconstituted tobacco leaves. The coating amount of reconstituted tobacco leaf products is contr...

Embodiment 3

[0030] A method for regulating and controlling chlorine ions in reconstituted tobacco leaves, the method steps are as follows:

[0031] 1) Separating and purifying the extract produced in the extraction section of the reconstituted tobacco leaf production process to remove suspended solids;

[0032] 2) Pass 30% of the total mass of the purified extract through an anion exchanger for ion exchange to remove chloride ions in the liquid; the anion exchanger uses styrene anion resin and is regenerated with sodium hydroxide;

[0033] 3) Adjust the pH value of the extract after anion exchange treatment to 7.5 with malic acid;

[0034] 4) Mix 30% of the extracted solution after adjusting the pH value with 70% of the extracted solution that has not undergone ion exchange treatment;

[0035] 5) Concentrate and blend the mixed extract before entering the coating production to prepare reconstituted tobacco leaves. The coating amount of reconstituted tobacco leaf products is controlled at...

Abstract

The invention provides a reconstituted tobacco chlorine ion regulation and control method. The method includes the steps that suspended solids in extracting solution generated in an extraction section in the reconstituted tobacco production process are removed through separation and purification; ion exchange is conducted on 10-100% of the total mass of the purified extracting solution through an anion exchanger, and then chlorine ions in the solution are removed; the anion exchanger is used for regeneration through vinyl benzene anion resin and sodium hydroxide; the pH value of the extracting solution after ion exchange is adjusted to be in the range from 5.5 to 8 through malic acid, the extracting solution after ion exchange is mixed with the 0-90% of the extracting solution before ion exchange according to the 10-100% mass, coating production is conducted after the mixed solution is concentrated and mixed, the reconstituted tobacco product coating weight is counted according to product oven dry amount and controlled to be 40%, and then the chlorine ion content of reconstituted tobacco is regulated and controlled within the range from 0.1% to 0.8% by mass. According to the reconstituted tobacco chlorine ion regulation and control method, the problems that the chlorine ion content of the reconstituted tobacco is high and difficult to control can be solved.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method. Background technique [0002] Domestic papermaking reconstituted tobacco leaf manufacturing technology started relatively late, and it has been industrialized for less than ten years. Because of its broad application prospects in reducing consumption, reducing coke and reducing harm, and improving cigarette quality in the cigarette industry, it has gradually received more and more attention. more attention. At present, the production method of reconstituted tobacco leaves by papermaking method is mainly to use tobacco leaf fragments, tobacco stems and other non-tobacco fibers in the process of cigarette processing as mixed raw materials, solvent extraction, and the extraction liquid is concentrated as a coating liquid and extracted solid matter The reconstituted tobacco leaves that can be used in the cigarette industry are obtained by using the...
