Embodiment 1

[0033] (1) Dilute the ground tobacco powder slurry with water to make a suspension with a mass percentage of 3%, and stir;

[0034] (2) Slowly add cationic guar gum with a molecular weight of 300,000 (purchased from Danisco, or other commercially available cationic guar gum) into water under stirring conditions, and prepare cationic guar gum to account for the mass of the solution. The percentage of the solution is 1%, fully stirred for 20 minutes, then heated the solution to 40 ° C, kept stirring for 80 minutes and then set aside;

[0035] (3) adding water to the cationic guar gum solution dissolved in step (2) and diluting it again until the mass percent concentration of the cationic guar gum is 0.1%, to obtain a cationic guar gum solution for modification;

[0036] (4) Add the cationic guar gum solution for modification obtained in step (3) to the tobacco powder suspension prepared in step (1), and the amount added is as follows: the mass percentage concentration of cationi...

Embodiment 2

[0039] (1) Dilute the ground tobacco powder slurry with water to make a suspension with a mass percentage of 6%, and stir;

[0040] (2) Slowly add cationic guar gum with a molecular weight of 200,000 to water under stirring conditions, and prepare a solution in which the cationic guar gum accounts for 3% of the solution mass, stir well for 15 minutes, and then heat the solution to 35°C, heat preservation and stirring for 70 minutes and then set aside;

[0041] (3) adding water to the cationic guar gum solution dissolved in step (2) and diluting it again until the mass percent concentration of the cationic guar gum is 0.3%, to obtain a cationic guar gum solution for modification;

[0042] (4) Add the cationic guar gum solution for modification obtained in step (3) to the suspension of tobacco powder prepared in step (1), and the amount added is as follows: the mass percentage concentration of cationic guar gum relative to the powder pulp is 0.5 %, stirred for 30 minutes, and t...

Embodiment 3

[0045] (1) Dilute the ground tobacco powder slurry with water to make a suspension with a mass percentage of 10%, and stir;

[0046] (2) Slowly add cationic guar gum with a molecular weight of 200,000 to water under stirring conditions, and prepare a solution in which the cationic guar gum accounts for 3% of the solution mass, stir well for 15 minutes, and then heat the solution to 35°C, heat preservation and stirring for 70 minutes and then set aside;

[0047] (3) adding water to the cationic guar gum solution dissolved in step (2) and diluting it again until the mass percent concentration of the cationic guar gum is 0.2%, to obtain a cationic guar gum solution for modification;

[0048](4) Add the cationic guar gum solution for modification obtained in step (3) to the tobacco powder suspension prepared in step (1), and the amount added is as follows: the mass percentage concentration of cationic guar gum relative to the tobacco powder pulp is 0.7 %, stirred for 30 minutes, ...

Abstract

The invention discloses a modified tobacco powder pulp, a preparation method and application thereof. The modified tobacco powder pulp is obtained by mixing a cationic guar gum aqueous solution with a mass percentage concentration of 0.1-0.5% and a tobacco powder pulp suspension liquid with a mass percentage concentration of 3-15% according to a mass ratio of 0.003-0.01:1. The preparation process of the modified tobacco powder pulp described in the present invention is simple and requires relatively low equipment; the modified tobacco powder pulp can be applied to the preparation of tobacco sheets according to the existing technology, and it can be realized without major modification of the production line and equipment. Compared with the unmodified tobacco sheet, the tensile strength of the tobacco sheet prepared from the obtained modified tobacco powder pulp is increased by 20-40%, and the crushing rate is reduced by 15-35%. Therefore, the loss in the production process is very small, and it is more suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a modified tobacco powder pulp and its preparation method and application. Background technique [0002] Tobacco sheet, also known as reconstituted tobacco or homogeneous tobacco, is a comprehensive utilization product in tobacco industrial and agricultural production. Its production and application were developed in the 1950s and 1960s. This technology is to process the discarded tobacco stems, tobacco powder and some low-grade tobacco leaves in the entire cigarette production process (including leaf threshing and other processes) through different processing methods to prepare Products whose properties are close to or better than natural tobacco leaves are then applied to cigarette production. [0003] The main raw materials for the production of paper-making tobacco sheets are wastes from the entire cigarette production process (such as tobacco stems,...
