Description

Granular carbon heating cigarette

Technical Field

The utility model relates to a granular carbon heating cigarette, and belongs to the technical field of novel tobacco products.

Background

The cigarette is heated by transferring the tobacco fragrance to a consumer in a heating and non-burning mode, so that the tobacco is heated only at a lower temperature (generally lower than 500 ℃), tar and a large amount of harmful compounds caused by high-temperature burning of the tobacco are avoided, and secondary smoke is not generated due to the fact that basically no side-stream smoke exists, and the public environment is not affected, so that the cigarette is more and more concerned and favored by the consumer.

At present, heating cigarettes can be classified into carbon heating type, electric heating type and chemical reaction heating type according to the type of heat source, wherein the carbon heating cigarettes become one of the main types of heating cigarettes due to the advantages of safety, stability, rapidness, high efficiency, low price and the like. Currently, the research reports on carbon-heated cigarettes are mainly focused on the carbon heat source and the cigarette core material, wherein the research reports on the carbon heat source are more, the preparation technology is mature, and the carbon-heated cigarettes are applied to products such as "Premier", "Eclipse" of the Reno tobacco company and "Revo" newly introduced in 2015. The research on the cigarette core material mainly comprises filiform materials, blocky materials, granular materials and the like. For the preparation of carbon heating cigarette, a composite twisting or multiple twisting process is generally adopted, which has higher maturity for thread-shaped smoke releasing medium, but carbon heating cigarette taking granular material as smoke releasing medium cannot be prepared. In addition, compared with the filiform smoke release medium (mainly tobacco sheets), the granular material does not need to add exogenous fibers (such as wood pulp fibers, hemp pulp fibers and the like) in the formula, and has better sensory quality. It is therefore desirable to provide a carbon-heated cigarette having tobacco particles as a smoke-releasing medium, and to provide a method of making such a cigarette.

A portion of the heat source segment (15-30% of the length of the heat source segment) is disposed within the particle encapsulating member 22 of the particle segment 2 and directly adjacent the particulate smoke releasing material.

In specific implementation, the heat source material 11 comprises the following components in parts by mass: 75-90 parts of carbon powder, 7-15 parts of adhesive, 2-6 parts of graphite powder and 0.5-2 parts of combustion improver. Wherein the carbon powder is at least one of charcoal powder, bamboo charcoal powder and hydrothermal carbon powder, and the particle size is 500-2000 meshes; the adhesive is one of alginate, guar gum and starch; the particle size of the graphite powder is between 500-2000 meshes; the combustion improver is one of permanganate, chlorate, nitrate and peroxide. In this embodiment, the heat source material 11 is composed of: the charcoal powder (1000 meshes) is 85 parts, potassium alginate 10 parts, graphite powder (800 meshes) 4 parts and calcium peroxide 1 part.

If the quantitative amount is more than 30g/m²Bad smell of the smoke can occur; if the quantitative determination is less than 25g/m²And the adaptability of the machine rolling is poor. In this example, the wrapper 12 is measured at 26g/m²The air permeability was 80CU, and the combustion rate was 100 mm/min.

If the bulk density is less than 0.3g/cm³The particles are loose in accumulation, and although the smoke is released quickly and sufficiently in the early stage, the attenuation in the later stage is obvious; if the bulk density is higher than 0.9g/cm³The particles are more densely piled up, the absorption resistance is larger, and the early smoke release is insufficient. If the flow index is less than 65, the granule filling process is affected. In this example, the particulate smoke-releasing material 21 is composed of the following components in parts by weight: tobacco60 parts of powder, 10 parts of tea powder, 25 parts of glycerol and 5 parts of essence and spice.

In this example, the cut tobacco 31 was reconstituted tobacco cut by a thick paste method, and the glycerin content was 7%, and the cut tobacco was arranged in disorder.

In specific practice, the first molding paper 6 has a basis weight of 30 to 70g/m²The oil-proof grade is 6-8, the opacity is not less than 75%, and the whiteness reduction amplitude is less than 30% after the paper is heated at 300 ℃ for 5 min. If the quantitative determination is less than 30g/m²The oil-proof effect is poor, and the hardness of the first composite cigarette branch section is low; if the quantitative amount is more than 70g/m²The appearance lap of the first composite cigarette section is obvious, and the composite efficiency is low. If the oil resistance level is lower than 6, oil leakage appears on the surface of the cigarette; if the oil-proof grade is more than 8, the hasp is not firmly bonded during composite molding, and the first composite cigarette branch section is exposed. If the opacity is less than 75%, the covering power is not good, and the oil leakage problem is easy to occur. If the color difference change is higher than 30 percent after the cigarette is heated for 5 minutes at the temperature of 300 ℃, the defects that the cigarette appearance is carbonized seriously after the smoking is finished can be caused. In this example, the first molded paper 6 had a basis weight of 45g/m²An oil resistance rating of 7, an opacity of 80%, and a color change of 20% upon heating at 300 ℃ for 5 minutes.

In specific implementation, the solid filter rod 4 is composed of a fiber tow 41 and a fiber tow wrapping paper 42, wherein the fiber tow 41 is made of one of acetate fibers, polylactic acid fibers, polyethylene terephthalate fibers, polybutylene terephthalate fibers and polybutylene succinate fibers.
