Abstract
Description
Technical Field
[0001] The present disclosure relates to a method for manufacturing a cut filler tobacco material having improved filling power, a cut filler tobacco material, and the use of a binder for improving filling power.
Background Art
[0002] Improving the filling power of tobacco materials is a common target property known in the tobacco industry. Therefore, various methods for improving filling power have been developed, and the most common method is to impregnate the tobacco material with a solution and then remove the solution in a subsequent expansion process. During such an expansion process, high pressure is generated inside the cells of the tobacco material cells, and finally the tobacco material is expanded.
[0003] Although such processes may improve the filling power of the tobacco material, they do not guarantee that this filling power is maintained throughout the subsequent manufacturing processes of the tobacco material. Rather, due to the fragile nature of the tobacco material, during further manufacturing and transportation, the tobacco material further deteriorates and the filling power decreases again.
[0004] As a result, the present invention can prevent a decrease in filling power during the processing of tobacco materials.
Summary of the Invention
[0005] According to a first aspect of the present invention, there is provided a method for manufacturing a cut filler tobacco material having improved filling power, the method including the step of providing a binder to loose tobacco leaf pieces, the binder at least partially coating the individual loose tobacco leaf pieces and forming at least a partial coating on the tobacco leaf pieces.
[0006] Cut-filler tobacco material can be used for aerosol-generating articles, including filtered cigarettes, hand-rolled cigarettes, and other smoking articles where the material burns to form smoke, as well as articles that generate aerosols from aerosol-generating material without requiring the combustion of the aerosol-generating substance. Such articles are often called "heat-non-combustion" aerosol-generating articles because the aerosol-generating material is heated to a relatively low temperature to induce aerosol formation, but the combustion of the material contained within the aerosol-generating material is prevented.
[0007] Filling strength is a measure of the amount of tobacco material required to manufacture an aerosol-generating article. Tobacco material with improved filling strength indicates that the amount of this tobacco material required to manufacture an aerosol-generating article decreases compared to tobacco material with reduced filling strength.
[0008] A loose tobacco leaf can refer to an individual leaf that is not firmly attached to or stuck to other leaf pieces. A loose tobacco leaf can be considered the total amount of individual tobacco leaves.
[0009] The binder may facilitate the separation of tobacco leaf fragments.
[0010] Tobacco leaf fragments may separate within the humidity-regulating and flavoring drum, particularly due to temperature increases or rotation within the drum, or both.
[0011] Tobacco leaf fragments may be tobacco leaf shards. Tobacco leaf fragments may mainly consist of unprocessed tobacco, processed tobacco, whole-leaf tobacco, or tobacco leaf blades. Tobacco leaf fragments may also consist of tobacco strands. In particular, tobacco strands may be obtained from reconstituted tobacco. Tobacco leaf fragments may consist of at least one of tobacco stems, tobacco strips, tobacco midribs, cut fillers, or reconstituted tobacco strands.
[0012] Spraying a binder may be the only source of reinforcement.
[0013] The binder provided to the loose tobacco leaf pieces will at least partially coat the individual tobacco leaf pieces, thereby forming at least a partial coating over these leaf pieces. The binder may completely enclose at least one tobacco leaf piece, forming a complete coating around this tobacco leaf piece.
[0014] The coating formed by the binder may define separate layers on the outer surface of the tobacco leaf pieces. A single coating may extend to multiple individual tobacco leaf pieces.
[0015] The binder may be absorbed by at most only a portion of the tobacco leaf fragments. In particular, the binder may not be absorbed by the tobacco leaf fragments at all.
[0016] The binder, when combined with tobacco leaf fragments, may improve the structural stability of the binder. The structural stability of the tobacco leaf fragments may remain unchanged.
[0017] The binder can increase structural stability after application without requiring chemical interaction with the tobacco leaf fragments. This improvement in structural stability can be achieved solely within the binder and through adhesion between the binder and the tobacco leaf fragments. Interaction between the binder and the tobacco leaf fragments may not involve crosslinking, activation, or catalytic bonding of substances within the tobacco leaf fragments. The binder does not necessarily have to contain calcium citrate.
[0018] Improved structural stability can prevent tobacco leaf fragments from denature during processing, thus preventing material loss during manufacturing. The binder applied to loose tobacco leaf fragments at least partially encases the individual fragments, providing a protective coating. The coating can at least absorb, dissipate, or disperse the forces applied to the tobacco leaf fragments during processing, thereby reducing the forces applied to brittle tobacco leaf fragments. This can prevent fragment breakage, deformation, and volume reduction, improving their viability and filling capacity.
[0019] The binder binds tobacco dust particles and other small elements to the tobacco leaf pieces, resulting in the absence of tobacco dust particles and other elements during processing.
[0020] The method may further include a preparation step, in which tobacco leaf pieces are prepared, and the preparation step is performed simultaneously with or before providing the binder. During the preparation step, loose tobacco leaf pieces may be heated. Heating of the tobacco leaf pieces may cause them to spread or open. The tobacco leaf pieces may be heated to 30-80 degrees Celsius, preferably 50-70 degrees Celsius. Alternatively, the tobacco leaf pieces may be heated to 30-100 degrees Celsius, preferably 50-90 degrees Celsius, more preferably 80-90 degrees Celsius, and most preferably 85 degrees Celsius.
[0021] The method may further include a casing step, in which at least one casing is provided to the tobacco leaf pieces, and a binder is provided during the casing step. The binder may be provided together with at least one casing. The casing step may be performed after the preparation step.
[0022] The method may further include a blending step in which tobacco leaf pieces are mixed with at least one other type of tobacco leaf pieces. The blending step may be performed simultaneously with or after the casing step.
[0023] The method may further include a cutting step in which tobacco leaf pieces are cut into smaller widths. The smaller widths may be 4, 2, or 1.5 millimeters or less. The smaller widths may be 1 millimeter or less, preferably about 0.9 millimeters. The smaller widths may be in the range of 1.0 millimeter to 0.8 millimeters. The cutting step may be performed after the blending step. Further blending steps may be performed after the cutting step.
[0024] The method may further include a drying process in which the tobacco leaf pieces are dried to a desired water content. The desired water content may be 5 to 30 weight percent, preferably 10 to 20 weight percent. The drying process may be flash drying. The drying process may utilize a rotary dryer. The drying process may be microwave. The drying process may be performed after the cutting process.
[0025] The method may further include a mixing process in which at least one additive is provided to the tobacco leaf pieces and a binder is provided during the mixing process. The mixing process may occur after the drying process.

[0057] As shown in Figure 1, loose tobacco leaves 1 are removed from their storage container 2 via a robotic arm 3, placed on a conveyor belt 4, and transported directly to a humidification and flavoring drum (DCCC) 5. A mixture of steam and casing is then applied to the loose tobacco leaves 1 in the DCCC 5, thereby spreading, humidifying, and flavoring the aforementioned loose tobacco leaves 1. Alternatively, no flavoring is performed in the DCCC 5. The loose tobacco leaves 1 are then transported to a blend silo 6, where other grades of tobacco leaves are blended with the loose tobacco leaves 1. The blended tobacco leaves 1 are then transferred to a cutter 7, where the loose tobacco leaves 1 are cut to a maximum width of 1 millimeter. The loose tobacco leaves 1 are then transported to a flash tower dryer 8 to achieve the final desired moisture content. After this point in the process, a mixing step is performed, where at least one additive 12 is added to the tobacco leaves 1. Subsequently, at least one flavoring agent is sprayed onto the loose tobacco leaf pieces 1 in the cut drum 9. The loose tobacco leaf pieces are then transported to the final blend silo 10 before being distributed and divided into individual storage units 11.
[0058] The binder may be provided directly in the humidity-controlled flavoring drum 5 together with the additive 12, or in the drum 9 after cutting.
