Problems solved by technology

These tobacco stem treatment processes all start with reducing the harmful and irritating substance content of the tobacco stem itself, but this will cause a large amount of treated tobacco stem to be added to the cigarette formula in order to meet the specified tobacco smell requirements, resulting in cigarettes The product has a high grammage but a general taste problem

Embodiment 1

[0037] A processing technique for improving the smell of cut stem tobacco, comprising the following steps:

[0038] (1) The waste tobacco leaf material produced in the cigarette production process and the ethanol solution with a concentration of 60% are mixed at a material-to-liquid ratio of 1:10, placed in a water bath at 60 ° C for oscillating extraction for 60 min, and then filtered to remove solids, the obtained The filtrate is the tobacco extract.

[0039] The tobacco extract was heated, evaporated and concentrated to a solid content of 35%, and then mixed with water at 25°C in a mass ratio of 1:2.33 to serve as an impregnation solution for tobacco stem impregnation.

[0040] (2) After sieving the tobacco stems to remove the thin stems and stems with diameters less than 3 mm, wash the floating ash on the surface of the tobacco stems with normal temperature water at 25 ° C, and then immerse them in the above-mentioned dipping solution. The mass ratio of the tobacco stems t...

Embodiment 2

[0046] A processing technique for improving the smell of cut stem tobacco, comprising the following steps:

[0047] (1) The waste tobacco leaf material produced in the cigarette production process and the ethanol solution with a concentration of 50% are mixed at a material-to-liquid ratio of 1:15, placed in a water bath of 70 ° C for 90min shaking extraction, and then filtered to remove solids, the obtained The filtrate is the tobacco extract.

[0048] The tobacco extract was heated, evaporated and concentrated to a solid content of 30%, and then mixed with water at 20°C in a mass ratio of 1:2 to serve as an impregnation solution for tobacco stem impregnation.

[0049] (2) Screen the tobacco stems to remove the thin stems and stems with diameters less than 3 mm, and then wash off the floating ash on the surface of the tobacco stems with normal temperature water at 20°C. Then, the tobacco stems were heated to 50°C, and in a closed environment, ammonia water with a concentratio...

Embodiment 3

[0054] A processing technique for improving the smell of cut stem tobacco, comprising the following steps:

[0055] (1) The waste tobacco leaf material produced in the cigarette production process and the ethanol solution with a concentration of 70% are mixed at a material-to-liquid ratio of 1:8, placed in a water bath of 60 ° C for extraction for 80 minutes, and then filtered to remove the solid matter, the obtained filtrate That is tobacco extract.

[0056] The tobacco extract was heated, evaporated and concentrated to a solid content of 40%, and then mixed with water at 30°C in a mass ratio of 1:3 to serve as an impregnation solution for tobacco stem impregnation.

[0057] (2) Screen the tobacco stems to remove the thin stems and stems with diameters less than 3 mm, and then wash the floating ash on the surface of the tobacco stems with normal temperature water of 30°C. Then heat the tobacco stems to 60°C, and in a closed environment, firstly spray ammonia water with a con...

Abstract

The invention relates to the technical field of tobacco processing, in particular to a processing technology for improving the smell of cut tobacco. It comprises the following steps: extracting the waste tobacco leaf material obtained in the cigarette production process with a solvent to obtain a tobacco extract; immersing tobacco stems in the tobacco extract, so that the fibers of the tobacco stems swell; and immersing until the moisture content of the tobacco stems reaches 45-50 %; pressing the steeped tobacco stems until no clear water seeps out; drying and shredding the stem slices obtained by pressing the stems to obtain shredded stems. In the present invention, the tobacco stems are soaked in the tobacco extract solution, and then the excess water is removed by low-intensity treatment, and then the cut stems are processed, so that the effective tobacco components in the tobacco extract solution are retained in the cut stems, and the effective aroma in the cut stems is increased. ingredients, to reduce miscellaneous gas, improve aroma and taste, and increase the application ratio in cigarettes.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a processing technology for improving the tobacco flavor of cut stems. Background technique [0002] Tobacco stems are a by-product of the tobacco industry. Adding expanded cut stems to cigarette formulations is one of the main ways to utilize tobacco stems. Well-processed cut stems can increase the filling value of cut tobacco, reduce costs, improve the flammability of cigarettes, and reduce The amount of flue gas tar, etc. Paying attention to the processing of tobacco stems and their products can improve the economic benefits of tobacco companies and the inherent quality of cigarettes. Because the main components of tobacco stems are some cell wall substances and macromolecular substances such as starch and protein, compared with tobacco leaves, the total sugar, total nitrogen, tobacco The amount of alkali, tar and effective aroma-causing ingredients are relatively ...
