Embodiment 1

[0025] Use 500-mesh hematite as raw material, wash repeatedly until the filtrate is clear, dry at 100°C for 10 hours, add NaCl solution with a concentration of 0.5mol / l, stir and react at 90°C for 3 hours, and the stirring speed is 200r / min, the solution was filtered and washed with distilled water until no Cl — The residue is then calcined at 100° C. for 8 hours to obtain a modified zeolite for future use. Add the prepared modified zeolite to the paper-making tobacco sheet extract, the amount of modified zeolite added is 100kg / t, stir for 2 hours, the stirring speed is 300r / min, filter, and obtain the tobacco sheet used in the papermaking method Extraction solution with low heavy metal ion content produced by dip coating.

Embodiment 2

[0027] Use 800-mesh hematite as raw material, wash repeatedly until the filtrate is clear, dry at 105°C for 10 hours, add NaCl solution with a concentration of 0.8mol / l, stir and react at 85°C for 4 hours, and the stirring speed is 400r / min, the solution was filtered and washed with distilled water until no C1 - The residue is then calcined at 105° C. for 10 hours to obtain a modified zeolite for future use. Add the prepared modified zeolite to the paper-making tobacco sheet extract, the amount of modified zeolite added is 80kg / t, stir for 3 hours at a stirring speed of 400r / min, and filter to obtain the paper-making tobacco sheet Extraction solution with low heavy metal ion content produced by dip coating.

Embodiment 3

[0029] Use 1500 mesh hematite as raw material, wash repeatedly until the filtrate is clear, dry at 105°C for 12 hours, add NaCl solution with a concentration of 1.0mol / l, stir and react at 80°C for 4 hours, and the stirring speed is 400r / min, the solution was filtered and washed with distilled water until no Cl — The residue is then calcined at 120° C. for 12 hours to obtain a modified zeolite for future use. Add the prepared modified zeolite to the paper-making tobacco sheet extract, the amount of modified zeolite added is 60kg / t, stir for 3 hours at a stirring speed of 600r / min, and filter to obtain the paper-making tobacco sheet Extraction solution with low heavy metal ion content produced by dip coating.

Abstract

The invention provides a preparation method of a modified extracting solution and a method for reducing contents of heavy metal ions in a papermaking method tobacco sheet. The extracting solution is prepared by adopting modified epidesmine, and used for a technology for the low contents of the heavy metal ions in dipping and coating production of the papermaking method tobacco sheet. The available heavy metal materials are mainly produced by factors such as soil, air and fertilizer for tobacco planting, and a mechanical contact in a tobacco manufacturing procedure, and tobacco stems and tobacco powder for manufacturing the tobacco sheet come from natural tobacco leaves. A paper base is recoated by extracts of the tobacco stems and tobacco powder in the manufacturing process of the papermaking method tobacco sheet. The modified epidesmine has a very good ion-exchange property; and after the epidesmine is added to recoated paint for reaction, the modified zeolite is removed by filtering, so that the contents of the heavy metal ions in the tobacco sheet are lowered, cigarettes have no offensive odor, and the method has the characteristic of simple technology, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to a method for manufacturing a modified extract and a method for reducing the content of heavy metal ions in paper-making tobacco sheets. Background technique [0002] With the increasingly prominent environmental problems, people pay more and more attention to the environment, and the content of heavy metal elements in tobacco has a tendency to increase. Especially compared with the brands of foreign developed countries, the content of heavy metal elements in some products may be relatively high. This is It is caused by soil, atmosphere, fertilizer, and mechanical contact during tobacco processing. Under the existing natural environment, it is difficult to reduce the heavy metal content in cigarettes from the process. [0003] Tobacco sheet by the papermaking method is to apply the extract of tobacco stem and tobacco powder, various flavor additives and coatings on the...
