Embodiment 1

[0021] Embodiment 1 (contrast shredded stem 1#)

[0022] Tobacco stems are made into shredded stems by conventional methods in the art, and used as a contrast, specifically through the following processing steps:

[0023] 1) Pre-cutting treatment: the tobacco stems are washed, stored, and heated to a moisture content of about 35%;

[0024] 2) Stem pressing and shredding: using a stem pressing machine to press the wet tobacco stems, and shredding machine to shred, the thickness of the stem is 0.8mm, and the shred width is 1.0mm;

[0025] 3) Drying: Airflow drying process is adopted, the process gas temperature is 200°C, the outlet moisture content is controlled at 12.5%-14.5%, and the outlet temperature is 50-60°C.

[0026] Using the method described in "YC / T 152-2001 Determination of Filling Value of Cigarette Shredded Tobacco", the filling value of the control cut stem was measured as 6.1cm 3 / g.

Embodiment 2

[0027] Embodiment 2 (stem shredded 2#)

[0028] (1) Preparation of first-grade cut stems: According to the current common preparation process for cut stems, the tobacco stems are washed, stored, warmed, pressed, and shredded to prepare first-grade cut stems.

[0029] (2) Water extraction of cut stems: extract the first-grade cut stems with 5 times the mass of hot water at 60°C for 40 minutes.

[0030] (3) Separation of shredded stems: centrifuge the mixture in (2) with a horizontal screw centrifuge to remove the extract.

[0031] (4) Feeding: after centrifugation, the shredded stems are added with a feed liquid containing 10% magnesium chloride and other spice ingredients, and the weight of the feed liquid is 2% of the weight of the stem feed.

[0032] (5) Drying and expansion of shredded stems: Airflow drying process is adopted, the process gas temperature is 180°C, the outlet moisture content is controlled at 12.5%-14.5%, and the outlet temperature is 50-60°C.

Embodiment 3

[0034] Embodiment 3 (stem shredded 3#)

[0035] (1) Preparation of first-grade cut stems: According to the current common preparation process for cut stems, the tobacco stems are washed, stored, warmed, pressed, and shredded to prepare first-grade cut stems.

[0036] (2) Water extraction of cut stems: extract the first-grade cut stems with 10 times the mass of normal temperature water for 60 minutes.

[0037] (3) Separation of shredded stems: centrifuge the mixture in (2) with a horizontal screw centrifuge to remove the extract.

[0038] (4) Feeding: after centrifugation, add the feed liquid containing 5% ammonium polyphosphate and other flavor components to the shredded stems, and the weight of the feed liquid is 1% of the weight of the stem feed.

[0039] (5) Drying and expansion of shredded stems: Airflow drying process is adopted, the process gas temperature is 180°C, the outlet moisture content is controlled at 12.5%-14.5%, and the outlet temperature is 50-60°C.

Abstract

The invention discloses a preparation method of cut stems with a high filling value, which comprises the following steps: extracting water-soluble components in the cut stems, and adding a combustionregulating component to dry and expand the cut stems. The water-soluble components in the tobacco stems account for about 50% of the weight of the tobacco stems, contribute little to the sensory quality of the cut stems, and generate tar and harmful components during cigarette burning and smoking. The volume of the cut stems is determined by insoluble cell wall framework tissues, after the water-soluble components are extracted and abandoned, the weight of the cut stems is remarkably reduced, but the volume change is not large, the volume occupied by the finally obtained cut stems per unit weight is increased, and a higher filling value is achieved. The combustion rate of the extracted cut stems is too high, smoke irritation is large, and therefore a certain amount of combustion regulatingcomponents need to be added, and the combustion rate of the cut stems is controlled. Compared with the prior art, the cut stem filling value of the cut stem prepared by the method can be increased bymore than 20%.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for preparing cut stems with high filling value. Background technique [0002] Reducing cigarette tar is a main direction of international cigarette development. Reducing tar can reduce smokers' dependence on nicotine on the one hand, and reduce smokers' intake of harmful ingredients, which is in line with the basic requirements of the Framework Convention on Tobacco Control. Since tar is mainly formed by the combustion and pyrolysis of shredded tobacco components during the smoking process of cigarettes, increasing the filling capacity of shredded tobacco and reducing the filling amount of tobacco ingredients in cigarettes can reduce the combustible tobacco substances in each cigarette, thereby reducing the tar release of cigarettes quantity. The shredded tobacco filling value is the volume occupied by unit mass under the continuous action of shredded tobacc...
