[0035] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: [Figure 1] 1 shows a process flow chart illustrating the method of the present invention. [Figure 2] 1 shows a simplified illustration of tobacco passing through an apparatus for processing the tobacco material. DETAILED DESCRIPTION OF THE INVENTION

[0036] After harvesting, tobacco material can be processed in a variety of ways to provide material for consumption. One of the processes is drying. The purpose of drying is to remove moisture from the tobacco material. Other changes in the tobacco material are generally not required or desired in conventional curing processes. is not seen.

[0037] Moisture has many effects on tobacco materials, their processing characteristics, and the final product itself. Moisture measurement is important in tobacco industry products. It is important to understand that conflicting definitions and terminology are used within the tobacco industry. "Moisture" or "moisture content" is often used to mean the water content of a material. Generally, but in relation to the tobacco industry, "moisture" as water content and oven volatiles It is necessary to differentiate between "moisture" as a solid substance and "water content" as a solid substance. The volatile content is defined as the percentage of volatile components in the total mass of a solid material. It includes water and all other volatile components. The bone dry mass is the mass of a substance that is volatilized by heating. The mass remaining after the radioactive material is ejected. It is expressed as a percentage of the total mass. Volatile matter (OV) is the mass of volatile matter that is evaporated.

[0038] The moisture content (oven volatiles) was measured by heating the sample in a forced draft oven at 110°C ± 1°C. It is measured as the mass loss after drying for 3 hours ± 0.5 minutes at the adjusted temperature. To cool the sample, let it cool at room temperature in a desiccator for approximately 30 min.

[0039] Unless otherwise specified, all references to moisture content in this specification refer to oven volatiles (OV). do.

[0040] Various drying devices are known, and typically they are designed to achieve the desired moisture content of the resulting dried tobacco. The amount is selected depending on the amount and the properties of the tobacco material being cured.

[0041] Cased-Leaf Dryer (CLD) produces very low final moisture content (approximately 4%). It is a type of device that cures tobacco leaves (not cut tobacco) for a short time. The initial moisture content of tobacco leaves dried using such equipment is usually about 28% to about 36%. The drying process involves placing tobacco in a perforated band. The tobacco passes through the holes in the band. The bands are not directly heated but are dried by passing hot air through the dryer. The tobacco is heated indirectly by the hot air passing through it. The tobacco remains in contact with the band during drying. The temperature of the heated air used to dry the tobacco leaves is usually 80 ℃~170°C, and in most cases it is 100°C~140°C. Even when operating at 50°C, hot air is rich in oxygen and cigarettes can get into "hot spots". The temperature of the cigarette cannot exceed 100°C because it will ignite.

[0042] Other types of tobacco drying equipment include the Flash Tower Dryer and the Flu The drying process is carried out by air / steam passing through the dryer. The dryer involves creating turbulence in the tobacco flow with a heated mixture. Instead, an air / steam mixture is heated. Dryer is used for chopped petioles, which tend to have initial moisture content in the range of 28% to 50% OV. HTD (High Temperature Dryer), HXD (High Expansion Dryer) Flash Dryers (including Flash Dryers) and Air Dryers Tower Dryers do not have a floor but rely on a heated air / steam mixture However, they are mainly composed of chopped petioles, sometimes with initial moisture content in the range of 20% to 36% OV. Therefore, to dry chopped petioles with an initial moisture content in the range of 28% to 50% OV, The residence time of tobacco in the Flash Tower Dryer is extremely short. On the other hand, cigarettes are smoked in the Fluidized Bed Dr. The tobacco processed by such a device may be dried for several minutes in the dryer. The final moisture content is approximately 10% OV. In both of these dryer types, the tobacco temperature is , approximately 50℃ to 100℃.

[0043] Yet another conventional type of device for drying tobacco is the Drum Dryer. The dryer utilizes a heated metal drum, and the drying process is a combination of air drying and heating via a heated surface. This can be considered a combination of drying and drying. The rotation of the drum rotates the tobacco, It creates turbulence between the tobacco and the air at a level of 6 degrees. The temperature can only be between 0 and 130°C. The final moisture content is greater than 10%. Typically, the moisture content of the starting material is greater than the tobacco species being cured. The initial moisture content of the cut leaf blade is 20% to 26%, and that of the cut petiole is The amount is 28% to 50%. Dry in a drum dryer for 3 to 4 minutes (for chopped petioles) or 4 minutes. After a processing time of ~7 minutes (for chopped tobacco), the moisture content of the processed tobacco is 12-15%. become.

[0044] In contrast to these conventional processes and devices, the tobacco processing method and processing method of the present invention A key aspect of the device is that it dries tobacco to an extremely low moisture content, between 0 and 10% OV. and intermittently contacting the tobacco with one or more heated surfaces. include.

[0045] Exposing tobacco to a hot surface reduces the tobacco to a very low moisture content (based on the volatiles in the oven). In addition to drying the product (based on the desired composition), in some embodiments, the method of the present invention further comprises: It has been found to lead to one or more biological or physical changes. - Significant improvement in the sensory properties of chopped petioles, - For example, 70% to 90% sugars in processed chopped petioles and processed chopped leaf blades Significant reduction in portion size, - For example, in the case of treated chopped petioles and treated chopped leaf blades, 20% to 50% A significant decrease in the amount of cotin - For example, in the case of treated chopped petioles and treated chopped leaf blades, 50% to 90% A significant decrease in the analytical value of ammonia and - Significant increase in filling value, e.g. 15%-50% for treated shredded petioles increase.

[0046] Treatment of tobacco material according to the methods of some embodiments of the present invention may result in chemical changes within the tobacco material. In at least some embodiments, these changes result in the organoleptic properties of the treated tobacco. Improve your performance.

[0047] The organoleptic properties of tobacco materials have traditionally been enhanced by a variety of different treatments. The material can be cured to prepare leaves for consumption. Tobacco material can be, for example, tobacco It may be further treated by maturation or fermentation to improve the organoleptic properties of the product. However, these processes are time-consuming and the quality of the resulting tobacco varies. It may be possible to improve the flavor and aroma of tobacco material at later stages of tobacco processing. The process of adding these to tobacco material involves adding one or more additives to the tobacco, and Processing steps and equipment may be required, which are expensive and time consuming.

[0055] In some embodiments, the tobacco material comprises leaf tobacco material. For example, the tobacco comprises about 70% to 10% leaf tobacco. In some embodiments, the tobacco material may comprise up to about 50%, about 60%, or even less than about 100% leaf blade material. About 70% or less, about 80% or less, about 90% or less, or about 95% or less of the leaf blade tobacco material In some embodiments, the tobacco material comprises 100% or less leaf tobacco material. For example, the tobacco material may comprise substantially entirely or entirely leaf tobacco material.

[0056] Alternatively or additionally, the tobacco material may be at least about 50%, at least about 60%, or at least about 10%. At least about 70%, at least about 80%, at least about 90%, or at least about 95% of the leaf blades It may also contain tobacco material.

[0057] When the tobacco material comprises lamina tobacco material, the lamina may be in the form of an entire leaf. In some embodiments, the tobacco material comprises cured whole leaf tobacco. In some embodiments, the tobacco material comprises substantially whole cured tobacco. In some embodiments, the tobacco material is free of shredded tobacco. In some embodiments, the tobacco is cut blade and / or expanded tobacco (dry ice expanded). (e.g. smoking, diet, etc.)

[0061] In some embodiments, the tobacco material comprises a blend of lamina and stem.

[0062] In some embodiments, the tobacco material is expanded tobacco, such as dry ice expanded tobacco (DIET). Includes Ko.

[0063] Repeated short-term exposure to high temperatures by intermittent contact between the tobacco and a heated surface In some embodiments, this intermittent contacting is accomplished by stirring the tobacco. The temperature of the heated surface, and therefore the temperature to which the tobacco is exposed, may be significantly greater than about 100°C. The temperature is very high, and in some embodiments, at least about 150°C. To ensure that the bacon does not burn from continuous exposure to such a hot surface for a long period of time. It is important to

[0064] In some embodiments, the surface of the tobacco material is heated by intermittent contact between the tobacco and the heated surface. It will be burned or charred. This is the result of sudden exposure to high temperatures. Not only is it effective in drying, but it also produces a tobacco that is different from the gentle curing process known in the prior art. It also serves as a means of processing.

[0065] In some embodiments, the amount of oxygen surrounding the tobacco during treatment may be reduced. Reduces the risk of "hot spots" forming as a result of exposure to tobacco on a heated surface This has the effect of reducing the risk of burning. Tobacco can be processed at higher temperatures with conventional processes and equipment. The amount of oxygen is reduced by adding steam.

[0066] Without wishing to be bound by any particular theory, the process of the present invention is divided into two stages. It is estimated that the first stage is when tobacco material is extracted during the steam distillation of certain tobacco materials. The drying occurs as a result of exposure to heat, which drives off volatile components, including water. This is where the major chemical changes in the tobacco occur. It is currently in the second phase.

[0067] The tobacco comes into contact with the heated surface for a short period of time, causing Maillard and This is thought to lead to an increase in caramelization and caramelization reaction products, many of which have desirable organoleptic properties. These properties are known to contribute to the thermal stability of the polymer, as will be further described in the Examples below. The Maillard reaction is a chemical reaction between amino acids and sugars, which are present in tobacco starting materials. However, this is only seen in small amounts in treated tobacco. It is a normally occurring non-enzymatic reaction that has a pleasant effect on the organoleptic properties of Maillard reaction products. In addition to the browning reaction, this reaction is also responsible for the browning of the material. The cured tobacco has been observed to be a darker brown color than the tobacco starting material.

[0068] In some embodiments, the processing steps for the tobacco material of the present invention, as described herein, may include the addition of flavor Improved properties or improved organoleptic properties (untreated or conventional curing process) This is because the flavor profile of tobacco is significantly higher than that of tobacco processed using only The tobacco flavor profile is maintained after conventional curing while reducing flavor or harshness. As used herein, the term "enhance" or "enhance" refers to the addition of flavor or Improvement or refinement of taste or taste qualities as identified by experienced smokers in relation to organoleptic properties This may include, but need not necessarily include, enhancing the taste. do not have.

[0069] As used herein, the organoleptic properties of tobacco materials refer to those that are used, for example, by a consumer in their mouths. The term refers to the organoleptic properties of the tobacco material itself when the tobacco material is used in combination with other tobacco materials. Organoleptic properties of smoke produced by burning tobacco or vapor produced by heating tobacco materials In some embodiments, the treated tobacco material has a desired consistency when used or consumed. and a tobacco product comprising the tobacco material having the organoleptic properties of:

[0070] In some embodiments, the method of the present invention provides a negative effect of the petiole on the overall performance of the blend. This has the unexpected benefit of reducing the sensory effects of mouth coatings, cellulose gums, and The contribution of the petiole to the saucy and "stemmy" taste is seen as a negative aspect of the overall character of the petiole. This is being done.

[0071] Furthermore, surface scorching has a physical effect on the tobacco material, and can also affect the individual cells of the plant material. It is thought that the moisture inside the bag expands when it is suddenly heated and evaporates.

[0072] In some embodiments, the temperature of the heated surface is in the range of about 100°C to about 300°C. In some embodiments, the temperature is at least about 105°C, 110°C, 115°C, , 120°C, 125°C, 130°C, 135°C, 140°C, 145°C, 150 °C, 155°C, 160°C, 165°C, 170°C, 175°C, 180°C, 1 85°C, 190°C, 195°C, or at least about 200°C. In this example, the temperatures of the heated surfaces are approximately 295°C, 290°C, 285°C, 280°C, and 2 75°C, 270°C, 265°C, 260°C, 255°C, 250°C, 245°C , 240°C, 235°C, 230°C, 225°C, 220°C, 215°C, 210 205°C or less, or about 200°C or less. The temperature is at least about 120°C to about 250°C or at least about 150°C to about 300°C. is.

[0073] When referring to the temperature of a heated surface, this specification refers to the temperature prior to contact with the tobacco material. This means that the heated surface cools down due to contact with the tobacco material and the drying process. Therefore, the exact temperature of the heated surface during the drying process is a function of the "drying process". For example, in the early stages as water evaporates from the tobacco, more Too much energy is utilized, leading to excessive cooling of the heated surface. It is the temperature of the heated surface prior to contact with the tobacco that can be easily and accurately measured.

[0074] In some embodiments, the temperature of the heated surface is controlled to minimize variation during processing. For example, a feedback mechanism may be used to ensure that the temperature is maintained within an acceptable range. and heating the surface when the temperature drops as a result of processing the tobacco material.

[0075] In some embodiments, the temperature of the heated surface is adjusted depending on the type of tobacco being treated. One reason this is appropriate is that different tobacco materials require different starting water. The processing involves removing different amounts of water and volatiles. Also, different tobacco species have different physical properties. For example, the leaf has a more fragile structure. The tobacco stem is woodier and sturdier.

[0076] In some embodiments, the heated surface is made of stainless steel or any material with sufficient heat transfer properties. In other embodiments, the metal is a metal such as steel or any other suitable metal type. The surface has sufficient heat transfer properties to be capable of being heated to the temperatures used in the methods described herein. It may be made of any material that has the desired properties. For example, a ceramic surface may be used. .

[0077] The heated surface may be, for example, a heating medium selected from the group consisting of oil, water, or steam. In some embodiments, thermal oil is the preferred heating medium. Alternatively or additionally, the heated surface may be directly heated. In an embodiment, the heated surface is electrically heated.

[0078] In some embodiments, the temperature of the heated surface prior to contact with the tobacco material is adjusted to treat the tobacco leaf. In some embodiments, the temperature is in the range of about 170°C to about 190°C. The temperature before contact with the tobacco material is above 200°C, preferably about 22°C for the treatment of petiole tobacco. The temperature ranges from 0°C to approximately 250°C.

[0079] When the tobacco material is repeatedly and intermittently contacted with the heated surface, the tobacco material is heated. If the heated surface is hot, the temperature of the tobacco will increase significantly. As a result of the treatment process, the temperature of the tobacco material increases to a peak temperature in the range of about 120°C to about 230°C.

[0080] In some embodiments, the tobacco material is heated under an inert atmosphere.

[0081] In some embodiments, an inert gas such as nitrogen, saturated steam, carbon dioxide, or a mixture thereof. An oxygen gas is added to the system to regulate the amount of oxygen and induce the desired chemical reaction during processing.

[0082] The treatment of tobacco material of the present invention has a drying effect, reducing the moisture content of the tobacco material. The moisture content of the tobacco material is between 0% and about 10% oven volatiles (OV). The moisture content of the treated tobacco material does not exceed about 10% 0.5%. The moisture content of the tobacco material is 9.5% or less, 9% or less, 8.5% or less, 8% or less, and 7.5% or less. Lower, 7% or less, 6.5% or less, 6% or less, 5.5% or less, 5% or less, 4.5% or less, 4% Below 3.5%, below 3%, below 2.5%, below 2%, below 1.5%, below 1% or In some embodiments, the moisture content of the treated tobacco material is about 2.5% OV or less. It is below %OV.

[0083] In some embodiments, the moisture content of the tobacco starting material is at least about 5% OV. In embodiments, the moisture content of the tobacco starting material is at least about 6%, 7%, 8%, 9%, 10%, , 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20% , 21%, 22%, 23% or at least about 24% OV. The moisture content of the Baco starting material is approximately 25% or less, 24% or less, 23% or less, 22% or less, and 21% Below, 20% or less, 19% or less, 18% or less, 17% or less, 16% or less, 15% or less, 1 4% or less, 13% or less, 12% or less, 11% or less, 10% or less, 9% or less, 8% or less, 7 % or less, or about 6% OV or less.

In embodiments, the moisture content of the tobacco starting material is at least about 12% to about 16% OV.

[0084] Thus, in some embodiments, the starting material used in the process of the present invention is a material that already contains tobacco. In some embodiments, the primary purpose of this tobacco treatment is to The objective is not to further reduce the moisture content of the tobacco starting material, but to reduce the temperature of the heated surface for a short time. The surface tanning caused by prolonged contact physically and chemically alters the tobacco. In some embodiments, this effect occurs when the tobacco is heated as a result of contact with a heated surface. is achieved without or substantially without burning.

[0085] In some embodiments, the moisture content of the tobacco material is adjusted during processing by adding moisture. Moisture may be introduced into the tobacco during processing in the form of water or steam. The tobacco material may be sprayed while the material is in contact with the intermittently heated surface.

[0086] In some embodiments, the introduction of moisture increases the moisture content of the tobacco material by 2% to 5%. In some embodiments, moisture is introduced at various locations throughout the process.

[0087] This tobacco is moistened during processing, so the moisture content will increase as the moistened tobacco is heated. The moisture content of the tobacco material is reduced again as it comes into contact with the surface it was previously exposed to. This may involve adding water multiple times by fluctuating up and down.

[0088] In some embodiments, the process of the present invention is carried out over a treatment time of at least about 1 minute to about 15 minutes. It involves repeatedly and intermittently contacting the tobacco material with one or more heated surfaces. In embodiments, the tobacco is intermittently contacted with the heated surface for at least about 1 minute, 2 minutes, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or at least about 14 minutes In some embodiments, the tobacco is intermittently contacted with the heated surface for a period of about 14 minutes or less. , 13 minutes or less, 12 minutes or less, 11 minutes or less, 10 minutes or less, 9 minutes or less, 8 minutes or less, 7 minutes or less, In some embodiments, the time is 6 minutes or less, 5 minutes or less, 4 minutes or less, 3 minutes or less, or about 2 minutes or less. The tobacco material is heated on the heated surface for a total of at least about 2 minutes to about 10 minutes, or at least about 2.5 minutes. Keep in contact for about 5 minutes.

[0089] Intermittent contact includes direct and continuous contact of the tobacco with a heated surface for approximately 5 seconds. In some embodiments, the average duration of direct and continuous contact is from about 0.1 seconds to about 3 seconds. is.

[0090] When we say intermittent contact of the tobacco material with a heated surface, we mean that every part of the tobacco material is heated. This means only temporary direct contact with the heated surface. The tobacco material moves relative to the heated surface, and the tobacco material is held in contact with the heated surface at a specific location. Do not stop for too long and / or heat the same area of tobacco for too long. This means that the tobacco material should not be left in direct contact with the surface. Prolonged contact with the coated surface can lead to combustion of the tobacco material, which can lead to the have adverse effects on the physical and chemical properties of the products, which may be further used in, for example, tobacco industry products. This results in tobacco material being treated as unsuitable material.

[0091] In some embodiments, the methods of the present invention further comprise agitating the tobacco material as it is being treated. In some embodiments, an apparatus is provided that includes a means for agitating the tobacco material.

[0092] In some embodiments, the tobacco material is preferably agitated by tumbling the tobacco material. This is done, for example, by picking, lifting, and dropping the tobacco to be processed, thereby tumbling the tobacco material. This may be done by inducing movement.

[0093] In some embodiments, the tumbling motion of the tobacco material is achieved by a mechanism such as one including one or more screws. In such a configuration, the screw is a helix that surrounds a rotating shaft. The helical surface is designed to pick up the tobacco material. The spiral surface scoops up at least a portion of the tobacco material being treated. The rotation of the screw causes the tobacco material to fall off the screw due to the rotating helical surface. In some embodiments, one or more screws are lifted up (by gravity). The tobacco material may be moved through the member to agitate the tobacco material. Such an arrangement allows for continuous processing of the tobacco. The surface and / or shaft of the screw are heated and used for processing tobacco. If two screws are used to move the tobacco material, these screws The blades are arranged parallel and positioned to contact and move all of the tobacco being processed. In some embodiments, the screw may include additional paddles to facilitate picking up of the tobacco material. These paddles may also be used to process the tobacco material. It may also be a heated surface that is used.

[0094] In another embodiment, the tobacco material may be agitated in a rotating drum. The tobacco may be disposed inside a drum. As the drum rotates, the tobacco material is picked up from the bottom of the drum and lifted up. a drum having an inner surface capable of maintaining contact with the tobacco material, such as a drum having a pick-up pad; The drum may have a rough surface or protrusions such as a buckle to facilitate picking up. As it rotates, the tobacco in contact with the inner surface of the drum is pulled by the rotation of the drum. The material falls off the wall of the drum (by gravity) and is lifted back down to the bottom of the drum. This causes the tobacco to tumble and mix. Irregularities on the drum's surface affect how long the tobacco will stay in the drum. The irregularities help control how much of the tobacco material remains in contact with the wall. Ensure that the material does not remain in contact with the drum as it falls (slides back to the wall). The rotation speed may also be adjusted by rotating the shaft. In some embodiments, the inner surface of the drum is The drum may be a horizontal or substantially In other embodiments, rotation about an inclined axis may be performed by This allows the tobacco to remain in contact with the inner surface of the drum for a longer period of time and also allows the tobacco material to be pulled longitudinally. The longitudinal movement of the tobacco as a result of the rotation of the drum may also Apart from this, the drum is also protected by appropriately positioned and / or angled protrusions on its inner surface. It may be executed as follows.

[0095] In other embodiments, the tobacco material may be agitated by an air stream. Therefore, it may be lifted and moved.

[0096] In some embodiments, the tobacco material is not agitated by the flow of air through the device. In one embodiment, the apparatus for treating tobacco material includes a device for agitating the tobacco material. It does not include a means of drawing up energy.

[0097] In some embodiments, the methods of the invention are continuous. For example, the tobacco starting material is connected to the apparatus. In another embodiment, the tobacco is continuously fed, processed, and exits the device as processed tobacco. The method of the invention is a batch process, in which a batch of tobacco starting material is fed into the apparatus and processed. processed to produce a batch of tobacco material and removed before a new batch is processed. It can be cut.

[0098] In some embodiments, after treatment, the treated tobacco may be conditioned. For example, in some embodiments, moisture may be added to the treated tobacco material. This is done by exposing the treated tobacco material to water and / or steam. In some embodiments, the water content is increased to about 10% OV or from about 10 to about 20% OV.

[0099] In some embodiments, after treatment, the treated tobacco may be cooled. This involves the use of a cooling belt, where ambient or cooled air is blown onto the treated tobacco layer. In other embodiments, the tobacco material is allowed to stand, passed through a cooling cylinder, or passed through an air cooler. Cooling by one or more of the following processes: early lifting and cooling through a fluidized bed You may do so.

[0100] The flow chart in Figure 1 outlines an example process for processing tobacco material. The tobacco starting material may be optionally subjected to, for example, conditioning of the raw petiole, followed by Conventional primary production (P) processes involving one or more of rolling, cutting and expanding / drying and mixing In some embodiments, the leaf blades may be subjected to pre-treatment, such as a thin-slicing (MD) process. After that, the product is conditioned, cased (if necessary), cut, dried, cooled and mixed. It may include.

[0101] The moisture content of the tobacco starting material is, for example, in the range of 14.5% OV. is delivered to a processing device where it is treated by intermittent contact with a heated surface. The tobacco material is agitated to create intermittent contact with the heated surface. The moisture content of the tobacco material decreases to about 0% OV due to intermittent contact with the heated surface. Once the treatment is complete, the treated tobacco material may be conditioned, if desired. In the exemplary process, this involves adding water or steam to the treated tobacco material to reduce its moisture content, e.g. For example, increasing the range to 14.5% OV.

[0102] The process parameters are set to maintain some or all of the physical characteristics of the tobacco material. For example, the tobacco material may be loose enough to accommodate tobacco in a smoking article or the like. It is filled with further processing to enable handling and / or processing for incorporation into a carbon-containing product. This allows the tobacco material to remain intact after undergoing the treatments described herein. This allows the product to be treated with the same standard processing as conventional cigarettes.

[0103] An example of an apparatus suitable for carrying out embodiments of the methods described herein is shown in FIG. In this embodiment, the device 1 includes two screws 2 in a dual screw configuration. The composition of the tobacco material is determined by the agitation or turbulence generated by the screw of this device. As a result, it is believed that the object comes into contact with the heated surface for a period of time of a few seconds.

[0104] Tobacco material 8 is processed in an apparatus 1 which includes a conventional conveying screw 2 having a helical surface 3 and a shaft 4. The screw 2 moves the tobacco material through the processing chamber 7 of the device 1. The screw 2 rotates, and the shaft 4 of the screw 2 is rotated by a drive mechanism 11 including a motor. do.

[0105] The tobacco starting material enters the processing chamber 7 through the tobacco inlet 5, where it rotates. The screw picks up the tobacco material, rotates it, and passes it through the processing chamber to the tobacco outlet 6. Move it towards.

[0106] More specifically, a mass of tobacco material 8 enters the processing chamber 7 through the tobacco inlet 5. As the clew 2 rotates, it picks up tobacco material, some of which comes into direct contact with the helix surface 3; There is also a possibility of contact with the shaft 4 of the screw 2. The screw is conveyed through the member 7 and dragged along the screw 2 so that it can rotate. It is lifted and dropped by one or more rotating screws. The tobacco then falls into a mass of tobacco material 8 being transported through chamber 7, The mass is constantly mixed and moved so that different parts of the mass are in the screw at different times. You will come into contact with -2.

[0107] In the illustrated embodiment, the surfaces of the screw 2 are heated, which is essential for the processing of tobacco according to the present invention. Thus, contact with the tobacco material occurs intermittently.

[0108] The screw 2 is heated by a heating medium supplied to the device 1 through a heating medium pipe 10. In an exemplary embodiment, the heating medium is thermal oil that is heated to a desired temperature. is.

[0109] Only a portion of the tobacco material being treated is in direct contact with the heated surface at any one time. As the baco is conveyed, the tobacco is tumbled and mixed, providing agitation, turbulence, and heating of the tobacco material. The desired intermittent contact with one or more surfaces is made. Individual contact times are 2-3 seconds at a time. It is believed that the force of the tobacco flow is induced by the shape of the screw. Ensure uniform processing throughout the tobacco mass.

[0110] In the illustrated apparatus, the processing chamber may be divided into different temperature zones 9. These zones represent different sections of the screw, which are heated separately. Thus, the device of the present invention can be configured to have surfaces that are heated to various temperatures. In some embodiments, the heated surface has different temperatures at different points during the process. It is desirable to control the scorching stage of drying and processing by exposing the bacon.

[0111] The tobacco treated according to the present invention may be used in tobacco industry products. Any item manufactured or sold in the tobacco industry, usually a) cigarettes Tobacco (including tobacco and tobacco derivatives) for bacos, cigarillos, cigars, pipes or rolling tobacco , whether based on expanded tobacco, reconstituted tobacco or tobacco substitutes) b) Incorporating tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes Non-smoking products such as snuff, snus, hard tobacco and heat-not-burn (HnB) products and c) aerosol generating devices such as inhalers, e-cigarettes, lozenges and gum. This example includes any tobacco nicotine delivery system. This example is not exclusive. It does not represent a complete list of products manufactured and sold by the tobacco industry, but merely exemplifies the range of products manufactured and sold by the tobacco industry.

[0112] The treated tobacco material may be incorporated into a smoking article. As used herein, the term "smoking article" are based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes Smokeable products, such as cigarettes, cigars and cigarillos, whether or not they are smoked This also includes non-combustion heating products.

[0113] The treated tobacco material may be used for rolling tobacco and / or pipe tobacco. .

[0114] The processed tobacco material may be incorporated into a "smokeless tobacco product." "As used herein, "means any tobacco product that is not intended to be burned. This includes, but is not limited to, includes any smokeless tobacco product designed to be placed in the user's mouth for a specified period of time, It is intended to come into contact with the user's saliva while in the mouth.

[0115] The treated tobacco material may be incorporated into smoking articles or smokeless smoking articles or hand-rolled cigarettes. and / or may be blended with one or more tobacco materials before being used in pipe tobacco. .

[0116] Example The method according to the invention was carried out on chopped expanded petioles (CES) with an (initial) moisture content of 14.5% OV. A single tobacco particle was used as the feed material, and the method used the apparatus shown in Figure 2 is processed.

[0117] This process involves placing the individual particles on a hot metal plate for several seconds before they fall back into the entire mass of tobacco being treated. This can be explained as exposing particles of tobacco (petiole) to the genus surface.

[0118] The residence time of the tobacco particle mass in the device (and therefore the processing time) is 1 to 5 minutes. The heated metal surface is like a screw that passes synthetic oil through the heated surface to bring it to the desired temperature. Heat is provided by a heated jacket.

[0119] Three different temperature sections were tested: 230°C, 240°C and 250°C. This means that the temperature of the heating medium (oil) used to heat the heated surface is set to these temperatures. This leads to different temperatures in different parts of the device.

[0120] The numbers and parameters in Table 1 below are for when the heating medium (oil) temperature is set to 250°C. These temperatures reflect the individual temperatures at intermediate stages of the process.

[0121] [Table 1]

[0122] In these experiments, the tobacco was treated with a residence time (or processing time) of approximately 2-3 minutes and a The tobacco processing rate was approximately 50 kg / h of chopped stems with a moisture content of 4.5% OV. The test was carried out using the following process.

[0123] This process can be divided into two distinct stages. In the first stage, the petiole particles When the heating medium (oil) temperature is 250℃, the moisture content of the petiole becomes 0% after about 1 minute. The second stage occurs during the remainder of the process, and the effect is called "scorching." The main changes occur through two stages.

[0124] Table 2 shows the chemical composition of untreated tobacco processed in an apparatus heated to different heating medium temperatures. It is compared with the chemical composition of tobacco.

[0125] [Table 2]

[0126] As can be seen from Table 2, the nicotine content of the processed tobacco increased with increasing heating temperature of 250°C. The chloride content is reduced by more than 50% and the sugars and ammonia content is reduced by more than 80% in total. The significant increase in filling values, reflecting the overall loss of organic matter, was due to the cellular structure of the treated tobacco. This shows the change in

[0127] These data indicate that the tobacco material was significantly altered throughout the treatment.

[0128] These changes can be translated into changes in the organoleptic properties of the treated material. This shows the smoke produced when the treated tobacco is burned, for example, in a cigarette. The organoleptic properties of this smoke are described in very favorable terms by experienced smokers. It is expressed that the processing of tobacco leads to the production of processed materials having beneficial and desirable properties. This indicates a reduction in some undesirable tobacco components and a sensory This is both in terms of improving the stimulation properties.
