Problems solved by technology

In these studies, due to the severe treatment conditions, the damage to the fiber part is obvious. After the action, the slurry is relatively viscous, and the dehydration molding effect is not ideal, and the stimulation and miscellaneous gas are obvious during suction.
In addition, most of the chemical treatments in the prior art are carried out before the extraction process, which will have adverse effects on the extract and concentrated paste rich in tobacco aroma components

Embodiment 1

[0023] ① Add quicklime to water, and react to prepare a clarified lime aqueous solution with a concentration of 0.04% to 0.16% for later use;

[0024] ②Using the papermaking method to produce reconstituted tobacco leaves, the steps are as follows:

[0025] a. Tobacco raw materials such as tobacco stems, tobacco powder, shredded tobacco pieces and low-grade tobacco leaves are added to water for extraction, and then solid-liquid separation is carried out to obtain extracts and solids respectively;

[0026] b. Concentrating the separated extract to obtain a concentrated extract;

[0027] c. Grinding and beating the separated solid matter, that is, the solid-phase tobacco material, to obtain a slurry with a slurry concentration of 2% to 5%;

[0028] d. The pulp after beating is subjected to alkali treatment with clarified lime aqueous solution, the solid-to-liquid ratio is 1:4 to 1:6, the treatment temperature is 25°C to 60°C, and the treatment time is 20 minutes to 45 minutes; ...

Embodiment 2

[0033] ① adding unslaked lime to water, and reacting to prepare a clarified lime aqueous solution with a concentration of 0.04% for subsequent use;

[0034] ②Using the papermaking method to produce reconstituted tobacco leaves, the steps are as follows:

[0035] a. add the tobacco stem raw material into clear water for extraction, and then carry out solid-liquid separation to obtain extract and solid respectively;

[0036] b. Grinding and beating the separated solid matter, that is, the solid-phase tobacco stem material, to obtain a slurry with a slurry concentration of 4%;

[0037] c. Alkali treatment is carried out on the slurry after beating with a clarified lime aqueous solution, the solid-to-liquid ratio is 1:6, the treatment temperature is 60°C, and the treatment time is kept at 60°C for 20 minutes;

[0038] d. The pulp is made by papermaking equipment to prepare reconstituted tobacco leaves by papermaking method with significantly improved softness and absorbency.

Embodiment 3

[0041] ①Add quicklime with water to react to generate a clarified lime solution with a concentration of 0.08%;

[0042] ②Pulping the solid-phase tobacco material extracted in the grinding and beating section of the papermaking reconstituted tobacco leaf production process, and the pulp concentration after beating is 2%;

[0043] ③ Alkali treatment is carried out on the pulp after beating with clarified lime aqueous solution, the solid-to-liquid ratio is 1:4, the treatment temperature is 60°C, and the temperature is kept at 60°C for 30 minutes during the treatment;

[0044] ④ Copy the alkali-treated slurry into shape.

[0045] It was tested that the softness and absorbency of the tobacco sheet prepared in this example were respectively increased by 5.8% and 75.0% compared with the tobacco sheet prepared without alkaline treatment with clarified lime aqueous solution.

Abstract

Disclosed is a method capable of remarkably increasing softness an absorptivity of papermaking-method reconstituted tobaccos. Water is added in quick lime, so that clarification lime aqueous solution with the concentration of 0.04% to 0.16% is produced after reaction; solid-phase tobacco materials extracted in a pulping working section in a papermaking-method reconstituted tobacco work flow are pulped, and the concentration of the pulp ranges from 2% to 5%; the pulp is in alkali treatment by the clarification lime aqueous solution, during treatment, the ratio of solid to liquid is 1:4 to 1:6, treatment temperature ranges from 25 DEG C to 60 DEG C, and treatment time ranges from 20 minutes to 45 minutes; and finally, the pulp after being in alkali treatment is formed in a paper making manner. Extracted solid fibers are treated by softer alkali reagent, the softness and the absorptivity of the papermaking-method reconstituted tobaccos can be improved, the fibers cannot be destroyed, and offensive and irritancy of the prepared reconstituted tobaccos are low.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method. Background technique [0002] Paper-making reconstituted tobacco leaves, or tobacco sheets, use tobacco waste such as tobacco stems, tobacco dust, shredded tobacco sheets, and low-grade tobacco leaves during the cigarette production process as raw materials to process thin-sheet tobacco regenerated raw materials that meet the requirements of cigarette formula. Papermaking reconstituted tobacco can maximize the use of tobacco raw materials, reduce the consumption of tobacco raw materials, reduce costs, and has the advantages of stable quality, low tar content and high filling value, which can increase the combustion degree of cigarettes, improve the internal quality of cigarette production, reduce Harmful ingredients in cigarettes can reduce the amount of tar and nicotine in cigarettes, which is beneficial to the health of smokers. The tar conte...
