Embodiment 1

[0025] (1) Tobacco stems are selected as raw materials, soaked in clear water to remove the epidermis and the cyst in the center of the tobacco stems, then cleaned and dried, and the moisture content is controlled at 16% to 18% for initial cutting, and the length is controlled at no more than 2cm; Then use a crusher to crush and screen the primary cut raw materials, and select granular materials with a particle size between 15 and 50 meshes as carbonization raw materials;

[0026] (2) Put qualified carbonized raw materials into a closed container for carbonization. Preheat the carbonized raw materials at 150°C, 200°C, and 300°C for 40 minutes to 45 minutes in sequence. Then heat the carbonized raw material to the low temperature section of 450°C to 500°C, keep it warm for 95min to 100min, and then cool it to room temperature by natural cooling to obtain the carbonized material;

[0027] (3) Sieve the carbonized material obtained, and sieve out the granular carbonized material...

Embodiment 2

[0032] (1) Tobacco stems are selected as raw materials, expanded by microwave expansion or solvent expansion method, and then naturally alcoholized, and then the moisture is adjusted to about 15% for crushing and screening, and the particles with a particle size between 20 and 40 mesh are selected The material is carbonization raw material;

[0033] (2) Put the carbonized raw material into an airtight container for carbonization, and preheat the carbonized raw material at 150°C, 200°C, and 300°C for 30min to 35min in sequence. Then heat the carbonized raw material to 400°C in the low temperature section, keep it warm for 60-65 minutes, and then cool it to room temperature by natural cooling to obtain the carbonized material;

[0034] (3) Pulverizing the carbonized material into 20-60 mesh powdered carbonized materials;

[0035] (4) Coat the obtained powdery carbonized material evenly on the paper filter rod core paper that can be coated on the paper tip rod or on the corrugat...

Embodiment 3

[0038] (1) Select tea cake as raw material, control the water content at 6% after cleaning, then use a crusher to crush and sieve the first-cut raw material, and select the granular material with a particle size between 15 and 50 meshes as the carbonization raw material;

[0039](2) Put the carbonized raw material into an airtight container for carbonization, and preheat the carbonized raw material at 120°C, 200°C, and 280°C for 30 minutes to 35 minutes in sequence. Then heat the carbonized raw material to the low temperature section of 400°C-450°C, keep it warm for 60min-65min, and then cool it to room temperature by forced cooling to obtain the carbonized material;

[0040] (3) Sieve the carbonized material obtained, and sieve out the granular carbonized material with a particle size of 30 to 60 mesh;

[0041] (4) Conduct moisture detection and adjustment on the carbonized material, spray deionized water to control the moisture to no more than 8%, and then evenly add it to t...

Abstract

The invention discloses a preparation method of a natural plant carbonated material and application thereof to a cigarette filter rod. The carbonated material is obtained by pretreating a natural plant raw material and then carrying out carbonization treatment. The application of the natural plant carbonated material is realized by the following steps: adjusting the water content of granulate carbonated material the grain diameter of which is 20-60 meshes to the water content of 6-8 percent; then evenly spreading the carbonated material on a filter rod tow; processing the carbonated material into a cigarette filter rod by using cigarette filter rod forming equipment; or crushing the carbonated material to a powdery carbonated material with less than 100 meshes; evenly coating the powdery carbonated material on paper filter rod core paper on which a paper filter rod can be coated or evenly spreading the powdery carbonated material on the paper filter rod core paper or corrugated filter rod paper for cigarettes; and processing the powdery carbonated material into the cigarette filter rod by using the cigarette filter rod forming equipment. The invention can be used for applying the carbonated material taking a natural plant as the resource to the cigarette filter rod, can effectively reduce harmful components in smoke gas of the cigarettes and cannot influence the smoking quality and the style character of Chinese cigarette products.

Description

technical field [0001] The invention belongs to the technical field of cigarette auxiliary material preparation, and in particular relates to a preparation method of a natural plant carbonized material used in a cigarette filter rod and its application in a cigarette filter tip. technical background [0002] In recent years, with the continuous emergence of smoking and health problems, "high aroma, low tar, low harm" has become the development direction of Chinese cigarette products. The requirement that the average tar content of cigarettes be controlled within 12mg / stick further promotes the development of cigarette products in the direction of low tar. [0003] As an important means of low-tar cigarette product development, activated carbon composite tip has become one of the most widely used filter materials at home and abroad. In foreign countries, activated carbon is usually used in the filter of low-tar cigarettes for filtration and adsorption, such as the global cig...
