Description
Technical Field
The application relates to the technical field of preparation methods of tobacco sheets, in particular to a novel method for preparing tobacco sheets by a rolling method.
Background
In recent years, with the sales of traditional cigarettes in developed countries, and the continuous increase of smoking inhibition in public places in many countries, new tobacco products such as electronic cigarettes, smokeless tobacco products and heating non-combustible tobacco products are rapidly emerging. The heating non-burning cigarette is a low-temperature cigarette, and is heated by an external heat source, so that tobacco leaves are just heated to a degree sufficient for emitting tobacco fragrance, tobacco substances cannot burn, and the high-dose atomizing agent is loaded, so that the atomizing agent is released by high-temperature heating when the functional reconstituted tobacco with a smoke effect is formed. At present, the traditional atomizing agent mainly takes glycerol and propylene glycol, but the propylene glycol and the glycerol have obvious defects: (1) the hygroscopicity of glycerol and propylene glycol is strong, so that the problems of adhesion phenomenon and yield reduction occur in the production and processing process of the heated nonflammable cigarettes; (2) the cigarette is easy to absorb moisture due to the moisture absorption characteristic of the traditional atomization agent added to the heated non-combustible cigarette. Erythritol has weaker hygroscopicity, can improve the coordination of cigarettes, is a widely accepted novel fuming agent, has the fuming effect equivalent to that of glycerol, and has refreshing sweet taste.
At present, when a rolling method is used for preparing a heating non-combustible tobacco product, the prepared tobacco sheet has the following problems of low fiber content, easiness in breakage, low filling value when a tobacco rod is manufactured by a tobacco roll, high suction resistance when the tobacco rod is sucked, unsmooth suction taste, insufficient tensile strength and easiness in breakage, so that the sensory quality and the utilization rate of cigarettes are affected.
The heating temperature of the heated non-combustible tobacco products is generally below 400 ℃ through an external heat source, and compared with the traditional cigarettes, the harmful substances are greatly reduced; but also has the problems of incomplete carbonization of the fuming material, incomplete release of fragrance, low fragrance concentration and the like caused by lower heating temperature. In the prior art, metal fibers are used for replacing original wood fibers, so that the heat conducting performance of the heated non-combustible tobacco products is improved. Although metals have excellent thermal conductivity, the addition of metals to heated non-combustible tobacco products requires consideration of the safety of the metals and the impact on sensory quality.
In summary, the following four problems to be solved when heating non-combustible tobacco products by the roller method in the prior art mainly exist: (1) When the heating non-burning tobacco products are prepared, the viscosity of the used atomizing agent is larger, so that the atomizing agent cannot be quickly absorbed by tobacco materials, the atomizing agent is added in a larger proportion on the basis of the prior art, the atomization effect is not obvious, and the atomizing agent cannot be completely absorbed by the tobacco materials, so that the smoke release amount of the heating non-burning tobacco products is lower, and the smoking experience of consumers cannot be met; (2) The existing atomizing agent has strong moisture absorption characteristic, so that adhesion moisture absorption phenomenon occurs in the production and processing process of the heated nonflammable cigarettes; (3) The prepared heating non-combustible tobacco product has the problems of low fiber content, easy breakage, insufficient tensile strength and easy breakage; (4) The heating temperature of the heated non-combustible tobacco products is low, and the heat conduction performance is poor, so that the release of tobacco aroma substances is incomplete, and the sensory quality and the utilization rate of cigarettes are affected.
