Description

Method of treating burley tobacco stems

The present invention relates to a novel method of treating Burley's tobacco stems for use as tobacco parsley. It also relates to the preparation of sheaths consisting of Burley's leaf tobacco stems treated using this method.

Typically, the tobacco plant tobacco products for smoking products are formed from the flakes of tobacco leaves, which are mostly separated from the leaf veins of the leaves during the dressing process. The vein portion of the tobacco material remains after the flakes have been removed and separated and is not normally used. So most of the tobacco's vein is being disposed of.

In order to increase the amount of vein areas in commercially available tobacco materials, it has been previously limited to process the removed tobacco veins and to combine the processed tobacco veins with flakes to form a vinegar. For example, well known techniques for processing tobacco veins include moisture treating the veins and rolling them to reduce thickness and weaken the porous structure of the veins. Such roll treatment techniques have been attempted for other types of tobacco, such as Virginia tobacco, Orient tobacco or combinations thereof. Another example for treating tobacco stems includes cutting the stems to reduce their size. It is not rolled or additionally processed before incorporation of the vein into each grass.

In the case of the roll processing of the beer, the finally flattened beer can be more easily blended with the tobacco flakes and incorporated into the cigarette sheath of the cigarette. However, the roll treatment process generally does not affect the flavor characteristics of the tobacco, so the tobacco stem has an undesirable effect on the overall flavor of the mainstream smoke produced when the vinegar is burned. This is especially true if the stem is a Burley tobacco leaf.

Thus, it may be desirable to provide a method for treating Burley's tobacco stem with improved flavor and appearance, thereby making it more suitable for use as a blending component of the sheath of smoking products. It may be particularly desirable if such a method can affect the flavor of Burley tobacco stems, such as the inclusion of the vein affects the flavor favorable to mainstream smoke. It may also be desirable to provide a method for treating Burley's tobacco stem using conventional devices and to be economical in performing such a method.

Thus, it may be desirable to provide a method for treating Burley's tobacco stem with improved flavor and appearance, thereby making it more suitable for use as a blending component of the sheath of smoking products. It may be particularly desirable if such a method can affect the flavor of Burley tobacco stems, such as the inclusion of the vein affects the flavor favorable to mainstream smoke. It also provides a method of treating Burley's tobacco stem using conventional apparatus and may be economically desirable to carry out such a method.

According to the present invention, there is provided a method for treating Burley's tobacco stem for use in tobacco grass.

Providing a Burley tobacco stem with a rolled thickness of 0.1 to 0.5 mm;

Coordinating the rolled vein to increase the moisture content;

Applying the packaging solution to the rolled and conditioned liquor;

Heating the dried vein with the applied packaging solution;

Re-harmonizing the vein after heating to increase the moisture content;

Cutting the re-harmonized tobacco stem; And

Drying the cut dried vein.

It is surprising to find that treatment of Burley's tobacco stem with the treatment method of the present invention has a significant and positive effect on both flavor and appearance. After this treatment, Burley's tobacco stems develop improved flavor and aroma. When combined with tobacco flakes to form a vinegar, the treated Burley tobacco stem can add a new, attractive flavor to the mainstream smoke. The treatment method of the present invention further darkens the color of Burley's tobacco veins to bring their appearance close to the color of Burley's tobacco flakes. In the case where the vein is finely cut to have a cutting width similar to the width of the tobacco flakes, the treated vein is visually indistinguishable from the tobacco flakes even though the content is relatively high.

As a result of this positive effect on Burley's tobacco stem from the treatment method of the present invention, Burley's tobacco stem can be used as an acceptable component in the herbicide. Burley's tobacco ave can also be added to each herd at a significantly higher rate than previously possible. This may improve the use of Burley tobacco material. The use of the method according to the invention can also have an environmentally positive effect by reducing the proportion of tobacco material that is discarded.

The use of Burley tobacco stems in place of Burley species or other forms of tobacco flakes is cost-effective. The reason is that the stems of Burley tobacco leaves are generally available at lower cost than tobacco slices. Burley's tobacco vein may be advantageous in that it can be processed using existing equipment already used to process tobacco flakes. This allows the method according to the invention to be carried out in an efficient and economical way. In addition, it reduces or eliminates the costs associated with disposing of Burley tobacco stems.

There are many types of tobacco material that can be preferably incorporated into the treated Burley tobacco stem. These types include, for example, Orient type, Virginia type or Castri type tobacco. The vinegar also contains a proportion of Burley tobacco flakes that must be processed before mixing.

In a preferred embodiment of the invention, the rolled Burley tobacco stem is combined with Burley tobacco flakes prior to conditioning of the stem. Thus, all series of processing steps are performed with the combined Burley's tobacco veins and slices. Optionally, the Burley stem wine can be treated separately in tobacco flakes and other production lines, and the tobacco flakes and Burley tobacco stem can be combined after the treatment.

Rolling Burley's tobacco veins to a thickness between 0.1 mm and 0.5 mm allows the veins to be produced to dimensions similar to tobacco flakes. This means that the blend of Burley tobacco stem and flakes can be run together through the processing device without separation of the stem and flakes. Burley's tobacco stem and flakes can be conveniently processed together under the same process steps and conditions, if necessary. As mentioned above, the method of the present invention can be carried out using existing apparatus already used for the treatment of tobacco flakes. This provides an efficient and economical way of processing blends of Burley tobacco stems and flakes without the need for additional equipment.

The item "thickness" here refers to the dimensions of Burley's tobacco veins that decrease in size during the roll treatment process. In general, the thickness corresponds to the dimensions of the tobacco vein in a direction substantially transverse to the direction of movement of the tobacco vein passing through the roller. After treatment of Burley's tobacco stem in the method according to the invention, the thickness of the tobacco stem generally corresponds to the three-dimensional compactness of each Burley's tobacco stem. The thickness of Burley's tobacco vein particles can be accurately measured using conventional measuring equipment with a microscope. The thickness of the vein particle is measured in the thickest part.

In the following embodiments of the present invention of the method of the present invention, certain criteria regarding the treatment of Burley type tobacco stems apply equally to the combination of Burley type tobacco stems and flakes, which in some embodiments can be produced prior to the conditioning step. .

The rolled Burley's tobacco stem is combined with Burley's tobacco flakes to produce a Burley's blend of at least 2 percent by weight, preferably at least 5 percent by weight, more preferably at least 6 percent by weight. At this level, the inclusion of tobacco stems will have a virtually undetectable effect on the flavor of the herbaceous plants incorporating the Burley species blend. However, due to the improved flavor and appearance of the treated Burley tobacco stem, tobacco stems can be included in the Burley blend at a significantly higher rate, while providing an acceptable formulation for use in cut grass. The proportion of Burley tobacco stems in the Burley species formulation can be anywhere up to 100%. However, it is preferred that the Burley blend contains between 2 and 40 weight percent Burley tobacco stem. More preferably between 6% and 20% by weight, particularly preferably between 2% and 20% by weight.

Conditioning of the Burley tobacco stem after the roll treatment is necessary to increase the moisture content of the Burley tobacco material. This was found to improve the efficiency of the next step where a casing solution is applied. Prior to the blending step, tobacco stems generally have a water content of 10% to 11% oven volatiles. During the blending phase, the moisture content of Burley tobacco stem is at least 15% o.v. And more preferably about 20% o.v. The corresponding harmonization step can be carried out in a combination of Burley tobacco stem and Burley tobacco flakes.

The moisture content of plant materials is expressed here as "% o.v. (oven volatile)". This was determined by measuring the weight percent loss from the tobacco stem due to evaporation when the material was dried at 103 ° C. for 100 minutes. The moisture content of Burley tobacco stem can be easily determined at any stage of the treatment method using this process.

Similarly, after applying the re-harmonized packaging solution of Burley's tobacco stem and Burley's tobacco sheet, it is necessary to increase the moisture content of the Burley's material upon heating of the material. This re-harmonization will ensure that it is flexible enough to cut without damaging or breaking the tobacco stem. Depending on the heating step and before the re-harmonization step, the tobacco stem has 5% and 18% o.v. Between 15% and 16% o.v. It is preferable to have between. During the re-harmonization step, the moisture content of Burley tobacco stem is increased to at least 20% o.v. Corresponding re-harmonization steps can also be carried out for the combination of Burley tobacco stem and Burley tobacco flakes.

The coordination and re-harmonization steps of the method of the present invention can be performed using existing techniques and apparatus. Preferably, each of the conditioning and re-harmonization steps consists of contacting the Burley tobacco stem with steam, water or steam and water. For example, according to one existing conditioning process, the tobacco stem is in contact with the steam and water flowing back as it rolls on a rotating cylindrical drum. The tobacco stem can optionally be harmonized or re-harmonized in the wet chamber.

After completing the conditioning step, the packaging solution is applied to the rolled, harmonized Burley tobacco stem using any suitable means, such as, for example, spraying. The packaging solution is preferably an aqueous solution consisting of sugar. In general, sugar will be the main component of the solution even if a suitable humectant such as glycerin can be added. If desired, flavoring ingredients may optionally be incorporated into the packaging solution. Corresponding steps may also be performed on the combination of Burley tobacco stem and Burley tobacco flakes.

Preferably, it has been found that the roll treatment of Burley's tobacco stem prior to application of the packaging solution significantly improves the absorption of the packaging solution by the stem. By rolling the vein to a thickness between 0.1 mm and 0.5 mm, the sheath of the vein is at least partially crushed and crushed. Thus a large area can be used to absorb the packaging solution. Without the roll treatment step, the rigid structure of the skin remains intact, making it difficult for the packaging solution to penetrate the inner structure of the jug through the skin. Increasing the packaging solution absorption will improve the flavor and visual appearance of Burley's tobacco stem after treatment with the treatment method of the present invention.

During the heating step in the process according to the invention, the Burley tobacco cigar stem to which the packaging solution has been applied is heated for reaction between the packaging solution and any component of the tobacco. This stage is responsible for the main development of the flavor of tobacco stems, which occurs as a result of the reaction of sugar and tobacco compounds in the packaging solution. The packaging of the tobacco stem and subsequent heating steps found that the flavor of the Burley tobacco stem was significantly improved compared to the untreated Burley tobacco stem. In particular, it has been found that the heating step significantly improves the flavor properties and the flavor of the vein material. This means that Burley tobacco stems can be used on the vinegar, while at the same time providing a neutral or favorable effect on the flavor of the mainstream smoke. The combination of the treatment of the Burley species tobacco stem with the roll and the packaging solution allows the Burley species tobacco stem to be used as an acceptable component of the herbicide.

In the heating step, the Burley tobacco stem is preferably heated to a temperature of at least 50 ° C. Heating of Burley's tobacco stem can be carried out using any suitable means. In a preferred embodiment, the tobacco stem is heated under a stream of hot air in a dryer. The hot air stream is preferably at a temperature between 70 ° C. and 140 ° C., preferably around 200 ° C., in order to heat the temperature of the tobacco stem to at least 50 ° C. This heating step can also be performed on the blend of Burley tobacco stem and Burley tobacco flakes.

Following the re-harmonization step as described above, the rolled Burley tobacco stem is cut to the appropriate cut width. The cutting width can be adjusted according to the desired use of the Burley species formulation. For example, very small, fine cut widths are preferred for smoking cigarettes, such as roll-your-own or pipe tobacco products, particularly for cigars intended for use in slim cigars. Preferably, the rolled Burley stem vein is cut with a cutting width between 0.3 and 1.3 mm, more preferably between 0.65 and 0.9 mm. Corresponding cutting steps may also be performed on the combination of Burley tobacco stem and Burley tobacco flakes.

The "cutting width" of Burley's tobacco stem is the width of the stem in the direction in which the tobacco stem is cut. When the Burley type tobacco vein particle is observed under a microscope, it is generally possible to observe the direction in which the vein particle travels along the cutting device. The cutting width corresponds to the distance between both sides of the particles of Burley's tobacco stem along this cutting direction. The cutting width of individual Burley tobacco stem vein particles can be accurately measured using a conventional measuring device with a microscope. The cutting width of the individual Burley tobacco stem vein particles is taken at a point along the cutting direction that yields the maximum cross-sectional area. When Burley tobacco is cut in two directions, the cut width for the purposes of the present invention corresponds to the largest of the cut widths measured in both directions.

In the drying step after the cutting step, the cut and rolled Burley tobacco stems are dried to lower the moisture level. Preferably, the moisture level is reduced to between 10% and 15% o.v., preferably between 12% and 14%. The drying step can be carried out at room temperature. However, it is preferred to heat the Burley type tobacco stem under a stream of hot air having a temperature between 70 ° C and 200 ° C. Suitable devices for drying cut and rolled Burley's tobacco stems include, but are not limited to, rotary dryers or flash tower dryers. This drying step can also be performed on a combination of Burley tobacco stem and Burley tobacco flakes.

The method according to the present invention made of the above steps can be carried out in a pre-rolled vein to a thickness of 0.1mm to 0.5mm off-line in the conventional roll treatment process. For example, a roll process can be performed in a separate tobacco leaf processing plant or the process of removing the vein of tobacco so that the starting material of the above-mentioned processing process may be a rolled process previously.

However, some embodiments of the present invention are suitable for incorporating a roll treatment process as part of the production process of each herb so that the roll treatment process can be carried out in the same plant or production facility as the remaining treatment steps. At this time, the rolled beer can be introduced directly to the production line of each grass. This method comprises the steps of: conditioning the vein to increase the moisture content; And rolling the vein to a thickness of 0.1 mm and 0.5 mm. If the starting material is a Burley stem vein already separated from the debris of Burley tobacco leaf, these additional steps may be carried out before the treatment step described above. However, the method of the present invention may be suitable for introducing a dressing step such that the starting material of the treatment process is an unprocessed Burley tobacco leaf. In this case the method comprises removing the vein from the Burley tobacco leaf; The step of cutting the vein to an average length between 15 mm and 80 mm can be done as an additional step, where these steps can be carried out before roughening and roll treatment of the vein, as described above.

The vein can be removed from Burley tobacco leaves using conventional dressing processes. It can be broken or cut in the dressing apparatus or in a separate step to reduce the length of the vein site to be suitable for the roll treatment process.

Prior to roll processing, coordination of the jug is necessary to increase the moisture content, so that the jug is flexible enough to be rolled without causing crushing or damage. Prior to the blending step, Burley tobacco stems generally have a moisture content of approximately 17% to 20% o.v. Will have The blending step increased the moisture content to 35% o.v. Or less, preferably 30% o.v. To increase below. In some cases, the moisture content is low, from 25% to 28%, to sufficiently prevent damage to the vein during roll processing.

The coordination of the veins can be carried out preferably by contact with water, steam or a mixture of water and steam. Preferably, the Burley tobacco stem is soaked for a long time to allow moisture to penetrate into its internal structure.

After the conditioning step, Burley's tobacco vein is rolled using a conventional one or two stage roll treatment process such that the thickness of the vein is reduced between 0.1 mm and 0.5 mm. The thickness of the rolled stem is reduced to a level close to that of Burley's tobacco flakes. Preferably the Burley tobacco stem is rolled to a thickness of 0.2 mm to 0.3 mm.

As noted above, the roll treatment of the veins to a thickness between 0.1 mm and 0.5 mm will at least partially weaken the porous structure of the vein material. In particular, the roll treatment results in at least partly crushing the shell of the cell of tobacco vein material. The weakening of the porous structure of the tobacco veins is clearly visible when the rolled tobacco veins are observed under a microscope. In addition, it will be clearly visible that the casing solution is applied to the rolled tobacco veins and absorbed into the porous structure due to the dark color of the Burley's tobacco veins after heating. If the Burley tobacco stem is treated with the method according to the invention, this will be evident from both the rolled thickness and the evidence of applying the casing solution to the Burley tobacco stem.

As noted above, the treated Burley species tobacco stem or Burley species combination of tobacco stem and flakes is for use as a component of the herbicide. According to the present invention, there is provided a method for preparing beetroot consisting of a rolled Burley tobacco stem. This method comprises the steps of treating Burley's tobacco stem using the method of the present invention as described above; Combining the treated Burley's tobacco stem or Burley's tobacco stem with Burley's tobacco flakes with at least one other type of tobacco flakes, swelled tobacco, or reconstituted tobacco to form a vinegar. Other types of tobacco flakes may be, for example, orient tobacco flakes, flue-cured tobacco lamina, or a combination thereof. Puffed and reconstituted tobacco, if present, can be formed into any suitable tobacco type using well known devices and methods.

Combination of other types of tobacco material with Burley tobacco can occur prior to the cutting and drying steps. The final blend can thus be cut and dried together in the same batch. Optionally, Burley's tobacco stem can cause the compounding to take place after the cutting and drying steps so that the compounding is the final step in the preparation of each herb.

Preferably, each herb is comprised of between 20 and 37 weight percent Burley tobacco blend. Wherein the blend is formed with at least 6% by weight and 100% by weight or less of the treated Burley tobacco stem and the remaining blend is formed with Burley flakes. Thus, the vinegar is comprised between about 0.3% and 37% by weight of Burley's tobacco stems produced using the method according to the invention.

Herbs consisting of Burley's tobacco stems treated using the method according to the invention can be incorporated into various smoking products. For example, sheaths can be used in tobacco rods of combustible smoking products, such as filter cigarettes, Cigarilot or cigars. Alternatively, each candle may be used. It can be used to provide a smoking product or electrically heated smoking system based on a substrate that generates a tobacco aerosol upon distillation. Alternatively, the vinegar can be used as a hand-rolled product or as a powdered tobacco for use in pipes, for example.

Smoking products consisting of sheaths comprising Burley's tobacco stems treated using the method according to the invention may be packaged in a pack, for example a pack formed of laminated white paper which is folded more than once. Such packs include but are not limited to packs with hinged lids, packs with slides and covers.

This invention will be described in more detail based on the examples.

Example

The process according to the invention was carried out with previously rolled Burley stems, separated from the debris of Burley leaves and rolled to a thickness of 0.2 mm. Burley's blend was formed by combining with the Burley's tobacco flakes before further processing of the rolled Burley's tobacco stem. Burley's formulation contains about 6.5% by weight of the rolled Burley's jug. The combination of tobacco stem and flakes can be thought of as an optional and optional embodiment, and the tobacco stem can be processed in the same manner without tobacco flakes.

In the conditioning step, the Burley blend was placed in a cylindrical drum and rotated to keep the tobacco stem and flakes moving continuously. A countercurrent of steam and water was passed through a cylinder to contact the Burley tobacco compound until the moisture content of the Burley tobacco stem was approximately 20% o.v.

The matched Burley species formulation was sprayed with a casing solution in which sugar was dissolved in water. In addition to sugar, the casing solution contains glycerin, which acts as a humectant.

After applying the casing, the Burley species blend was heated in high temperature air at a temperature of approximately 100 ° C. for 4-8 minutes in an afron dryer to raise the temperature of the tobacco to approximately 50 ° C.

After the heating step, the Burley species blend was cooled and reconditioned using methods and apparatus similar to the roughening step described above. The moisture content of Burley's tobacco stem was returned to approximately 20% o.v.

Burley's formulation was mixed with other tobacco materials including Bright tobacco and Puffed Tobacco to form a horn formulation. The Burley species blend comprises 25% by weight of the total herbicide.

The vinegar blend comprising Burley's tobacco stems was cut to a standard cut width of 0.9 mm and the moisture content continued to dry to a level of about 13% o.v. before continuing to storage or cigarette making lines.

It will be apparent that the degree of moisture, rolled vein thickness, cut width, proportion of Burley's tobacco veins, and other mediators of the treatment process may vary as described above depending on the desired properties and the intended use of the final herb.
