Problems solved by technology

[0003] Although adding some functional additives to cut tobacco can improve the whiteness of cut tobacco ash, it often brings some unpredictable safety hazards, so it is rarely used
[0004] In addition, due to the dense structure of cut stems, it is easy to burst when burned, which affects the ash property of cigarette packs, so it is generally not used directly in cut tobacco formulations
Although expanded shredded stems can greatly reduce the bursting situation, due to the high content of non-flammable components such as pectin, the burning ash is generally black, resulting in the blackening of cigarette ash and affecting the consumption experience of consumers.

Embodiment 1

[0034] Add 40°C warm water to the conventional expanded cut stems and filter them for immersion for 30 minutes. After repeating the dipping once, the cut stems are dried by air drying process to control the moisture content at about 8%. The eluted and dried cut stems are transferred into a rotating drum, sprayed into glycerin with 5% mass of cut stems under the condition of constant rotation, and taken out after 40min under reduced pressure and equilibrium diffusion at 400 mbar, which is the method described in the present invention. Cut stem products that enhance the whiteness of cigarette ashes.

[0035] The cutting rate of cut stems obtained by the above method is about 12%. The shredded stem was used to make cigarette (2#) with shredded tobacco according to the ratio in the original formula, and compared with the original cigarette (1#), the results are as follows:

[0036] Sample serial number Ash whiteness Tuff Index 1# 96.2 6.1 2# 121.2 4.9 ...

Embodiment 2

[0040] Add 60°C warm water to the conventional expanded cut stems and filter them for 20 minutes. After repeating the dipping once, the cut stems are dried by the air drying process to control the moisture content at about 10%. The eluted and dried cut stems are transferred into a rotating drum, and under the condition of continuous rotation, 15% of the cut stem mass is sprayed with glycerin, and then taken out after 20 minutes of decompression and equilibrium diffusion at 800 mbar. Cut stem products that enhance the whiteness of cigarette ashes.

[0041] The cutting rate of cut stems obtained by the above method is about 17%. The shredded stem was used to make cigarette (2#) with shredded tobacco according to the ratio in the original formula, and compared with the original cigarette (1#), the results are as follows:

[0042] Sample serial number Ash whiteness Tuff Index 1# 96.2 6.1 2# 126.4 5.5

[0043] As can be seen from the above table, com...

Embodiment 3

[0045] Add 50°C warm water to the conventional expanded cut stems and filter them for immersion for 20 minutes. After repeating the dipping once, the cut stems are dried by air drying process to control the moisture content at about 9%. The eluted and dried cut stems are sent into the rotating drum, and under the condition of continuous rotation, 10% of the cut stem mass is sprayed with glycerin, and then taken out after 30 minutes of decompression and equilibrium diffusion at 600 mbar. Cut stem products that enhance the whiteness of cigarette ashes.

[0046] The cutting rate of cut stems obtained by the above method is about 16%. The shredded stem was used to make cigarette (2#) with shredded tobacco according to the ratio in the original formula, and compared with the original cigarette (1#), the results are as follows:

[0047] Sample serial number Ash whiteness Tuff Index 1# 96.2 6.1 2# 124.1 5.1

[0048] As can be seen from the above table,...

Abstract

The invention discloses a method for treating cut stems that can improve the whiteness of cigarette ashes. The method comprises the following steps: (1) eluting cut stems; (2) using a repairing agent to repair the washed cut stems to restore Cut stems are resistant to processing strength, enabling them to be smoothly incorporated into cigarettes during normal cigarette production. After the shredded stems treated by the invention are added to cigarettes for use, the ash whiteness of the cigarettes can be improved by 15-30 units, the tuff index can be reduced by 1-2 units, and the sensory quality of the cigarettes changes little, and there is no potential safety hazard.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a method for processing cut stems which can improve the whiteness of cigarette ashes. Background technique [0002] In recent years, with the improvement of consumers' pursuit of cigarette quality, designers have begun to optimize some cigarette details, and the ash whiteness of cigarettes is one of them. Generally speaking, the whiteness of soot can be roughly divided into two types, one is the whiteness of the ash column, that is, the whiteness of the outer surface of the columnar ash after the cigarette is burned; , the whiteness of the tobacco burning ash after peeling off the cigarette paper. The ash column whiteness of cigarettes is mainly related to the combustion properties of the cigarette paper and its matching with the cut tobacco, while the ash whiteness of the cut tobacco mainly depends on the formula structure and additives of the cut tobacco. [0003] Although...
