Description

Technical Field

[0001] This patent relates to the technical field of cigarette processing technology, and specifically to a processing method and a pipe tobacco cartridge. Background Art

[0002] The domestic pipe market is experiencing rapid growth, with a compound annual growth rate of approximately 7.3%. By the end of 2024, the pipe market is projected to reach 16 billion yuan. The current pipe market encompasses both traditional heat-and-burn pipes and new heat-not-burn pipes. Traditional heat-and-burn pipes offer an irreplaceable smoking experience.

[0003] However, smoking a traditional heat-and-burn pipe differs from smoking a traditional cigarette. The main challenge lies in the filling technique. If the pipe is filled too tightly, the draw resistance increases, resulting in uneven combustion and easy flameout. If the pipe is filled too loosely, the pipe burns too quickly, easily overheating and losing flavor. If the bottom of the combustion chamber is neglected, it may leave gaps, resulting in a "well" (i.e., a burn through the center). The difficulty of mastering the filling technique causes many new pipe smokers to give up on smoking.

[0004] At the same time, filling the pipe tobacco is also a rather tedious process, involving multiple processes such as waking up the tobacco, rubbing it, picking impurities, multiple fillings, and trimming. This makes the steps of smoking the pipe tobacco more complicated, and it is difficult to achieve the convenience, speed and instant enjoyment like smoking traditional cigarettes and new heat-not-burn pipes.

[0005] Controlling the moisture content of pipe tobacco is also a crucial factor influencing the smoking experience of traditional heat-and-burn pipes. If the moisture content is too low, the pipe tobacco will be too dry, burn too quickly, and easily overheat, resulting in a harsh and unpleasant smoke and potentially damaging the pipe. If the moisture content is too high, the pipe tobacco will not burn fully, producing a large amount of smoke but a lack of rich flavor. It will also easily cause carbon deposits in the pipe, shortening its lifespan. However, pipe smokers generally estimate the moisture content of pipe tobacco by feel, which requires considerable experience, making it difficult for new smokers to accurately perceive the moisture content of their pipe tobacco.

[0006] Therefore, there is a need for a pipe tobacco cartridge that is suitable for traditional heated and burned pipes, is easy to carry and saves time, reduces the difficulty of filling, and has a stable moisture content of pipe tobacco for easy storage. Summary of the Invention

[0007] In order to overcome the problems of the conventional heating and burning tobacco pipe in the prior art, such as the cumbersome process of filling the tobacco pipe, which can affect the smoking experience, the difficulty of filling, and the loss of flavor caused by the difficulty of carrying and storing the tobacco pipe, and to improve the comfort and convenience of smoking the conventional heating and burning tobacco pipe, this patent provides the following technical solutions:

[0008] In a first aspect, a method for processing a pipe tobacco cartridge is provided. The pipe tobacco cartridge includes a cartridge jacket and a cartridge core. The processing method includes: step S1: adding raw materials and then rehydrating to obtain a mixed raw material with a first moisture content; step S2: adding an additive to the mixed raw material to obtain a first tobacco shred with a second moisture content; step S3: drying and inactivating the first tobacco shreds to obtain a cartridge core with a third moisture content; step S4: rolling the cartridge core and the cartridge jacket to obtain a pipe tobacco cartridge.

[0009] Furthermore, in step S1, the return air temperature of the rehumidification is 64-68°C, 68-72°C or 72-76°C; the temperature of the mixed raw material is 54-58°C, 58-62°C or 62-66°C; and the first moisture content is 15-17%.

[0010] Furthermore, the raw material is redried and aged tobacco leaves, including upper leaves, middle leaves and lower leaves; the weight percentage of the upper leaves is 33-37% WT, 37-41% WT or 41-45% WT; the weight percentage of the middle leaves is 33-37% WT, 37-41% WT or 41-45% WT; and the weight percentage of the lower leaves is 13-17% WT, 17-21% WT or 21-25% WT.

[0011] Furthermore, the aging time is 23 to 25 months, 25 to 27 months or 27 to 29 months; and the casing is made of cigarette paper or lower leaves.

[0012] Furthermore, step S2 includes: step S21: feeding the mixed raw material into a cutter to obtain mixed shredded tobacco; step S22: adding additives to the mixed shredded tobacco and fermenting the mixed shredded tobacco to obtain first shredded tobacco.

[0013] Furthermore, in step S21, the blade door pressure of the cutter is less than 5 kN; the width of the mixed tobacco is 1.5-1.7 mm, 1.7-1.9 mm, or 1.9-2.1 mm.

[0014] Furthermore, in step S22, the additives include, by weight, leather essence: rose essence: fructose: water = 1.5:2:20:76.5; the application ratio of the additives is 3-5%, 5-7% or 7-9%; and the addition accuracy of the additives is ≤1%.

[0015] Furthermore, the second moisture content is 18-20%; the fermentation method is anaerobic fermentation, and the fermentation container is selected from one of a sealed box, a sealed cabinet or a sealed bag; the fermentation temperature is 24-26°C, 26-28°C or 28-30°C.

[0016] Furthermore, in step S3, the third moisture content is 13-15%; the drying temperature is 56-59°C, 59-62°C or 62-65°C; the inactivation time is 18-26 min, 26-34 min or 34-42 min; and the inactivation method is one of ultraviolet inactivation, ion radiation inactivation, ozone inactivation, laser inactivation or ultrasonic inactivation.

[0017] In a second aspect, a pipe tobacco cartridge is provided. The pipe tobacco cartridge is made by the above processing method. The pipe tobacco cartridge includes a cartridge jacket and a cartridge core. The cartridge core includes an upper layer of shredded tobacco and a lower layer of shredded tobacco.

[0018] This patent has the following beneficial effects:

[0019] 1. This patent relates to the field of cigarette processing technology, specifically a method for processing pipe tobacco cartridges. This method defines a series of quality indicators, especially strict control of moisture content during processing, providing a suitable moisture content range of 14±1% for pipe tobacco cartridges. Pipe tobacco cartridges within this moisture content range are conducive to sealed storage and greatly improve the smoking taste;

[0020] 2. This patent also relates to a pipe tobacco cartridge, including a cartridge and a core. The pipe tobacco cartridges have different sizes and are suitable for pipes of the same size. The pipe tobacco cartridges are easy to carry, can be directly filled and smoked, and are convenient for storage. This solves the problems of high pipe filling skills, difficulty in filling, and cumbersome pipe filling processes, and eliminates the technical barriers for novice pipe smokers.

[0021] 3. The rolling density of the upper and lower layers of tobacco in the pipe tobacco cartridge in this patent is different. The rolling density of the upper layer of tobacco is greater than that of the lower layer of tobacco, which realizes the structure of the pipe tobacco cartridge that is tight at the top and loose at the bottom, making the combustion process more complete, not easy to deform during transportation, and improving the overall quality of the pipe tobacco cartridge.

[0022] 4. The product adopts traditional flue-cured tobacco as the raw material, and its style is more in line with the smoking habits of domestic pipe smokers. In the form of pipe tobacco cartridges, it changes the smoking form of traditional pipe tobacco, greatly simplifies the preparation process for smoking a pipe, reduces the difficulty for new pipe smokers, and makes smoking a pipe as enjoyable as traditional cigarettes, providing better technical support for the promotion of pipe tobacco.

[0023] First, some terms used in various embodiments of the present disclosure will be clarified.

[0024] Tobacco classification: According to the tobacco leaf preparation method, properties or main use, tobacco can be divided into flue-cured tobacco, sun-cured tobacco, air-fried tobacco, burley tobacco, spice tobacco and yellow flower tobacco.

[0025] Tobacco leaf classification refers to the subdivision of tobacco leaves within a category, categorizing them into different types based on factors such as production region, soil, climate, variety, and cultivation methods, resulting in differences in quality and usability. Tobacco leaves within the same type share certain characteristics, properties, and associated grades. Flue-cured tobacco can be categorized as: Strong-flavor, Light-flavor, and Medium-flavor.

[0026] Flue-cured tobacco grouping: Tobacco leaves within the same type are further divided based on leaf location, color, and other key characteristics related to overall quality. The goal is to ensure that leaves within the same group share key common characteristics and have similar intrinsic quality.

[0027] The national standard grouping system for flue-cured tobacco includes main groups and sub-groups. The main group refers to tobacco leaves with normal growth and development and proper curing, and the division factors are position and color; the sub-group refers to low-quality tobacco leaves caused by poor growth and development, improper harvesting or curing errors and other reasons, and the division basis is mainly based on the appearance characteristics of the tobacco leaves.

[0028] The main groups of leaves, divided by body part, include upper leaves, middle leaves, and lower leaves. The top 3-4 leaves are called the top leaves, the lower 4-5 leaves are called the upper second shed leaves, and the upper second shed and top leaves are collectively called the upper leaves. The middle 4-6 leaves are called the waist leaves, and the waist leaves are called the middle leaves. The lower 2-3 leaves are usually called the foot leaves, the upper 4-5 leaves are called the lower second shed leaves, and the foot leaves and lower second shed leaves are collectively called the lower leaves.

[0029] Pipe tobacco products refer to tobacco that is burned and smoked using a wooden straight or curved bowl. The tobacco is also called pipe grass. Usually, the pipe grass is made of various types of tobacco, such as flue-cured tobacco, burley tobacco, oriental tobacco, and sun-cured tobacco, which are compounded and fermented according to a certain percentage of components. Spices are added during fermentation to highlight the specific aroma.

[0030] Given that the production and preparation process of pipe tobacco is more handmade than other mass-produced tobacco products, its price per gram in the market is relatively high. In addition, each time it is smoked, 2 to 3 grams of pipe tobacco is consumed. Therefore, pipe tobacco has always been a niche high-end consumer tobacco product.

[0031] Pipe tobacco can be divided into two categories: aromatic and non-aromatic. Non-aromatic tobacco generally refers to all natural tobaccos without any added flavorings. High-quality non-aromatic tobacco only contains a small amount of distilled water to adjust the moisture content, without any other additives. Flavored tobacco is made by adding various natural or artificial flavors, such as vanilla, cherry, rum, and whiskey, to the tobacco to make it more palatable and more palatable to those around you.

[0032] In the following examples, unless otherwise specified below, 2024 Yunnan Kunming C3F Yunyan 99 flue-cured tobacco leaves were used.

[0033] In addition, this patent can also use the following flue-cured tobacco leaves: Chenzhou Guiyang B2F, C2F, X2F, Yongzhou Lanshan B3F, C2F, X2F, Sanmenxia Mianchi B2F, C3F, X3F, Guizhou Zunyi B2F, C2F, X2F, Bijie Dafang B3F, C3F, X2F, Guizhou Bijie B2F, C2F, X3F, Yunnan Yuxi B3F, C3F, X2F, Yunnan Kunming B2F, C3F, X2F, Yunnan Dali B2F, C3F, X2F, including tobacco seed varieties such as Honghua Dajinyuan, Cuibi No. 1, and Yunyan 97.

[0034] In the following embodiments, the wrapping paper may be wood pulp paper, linen paper, hemp paper, bamboo pulp paper, rice paper, paddy paper, slow-burning paper, ignition line paper, seasoning paper, non-adhesive paper, thickened paper, highly breathable paper, biodegradable paper, chlorine-free bleached paper, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Raw material configuration: The raw materials for the formula are redried tobacco leaves, which are threshed and redried and aged for 23 to 25 months, 25 to 27 months or 25 to 28 months. The formula is a light fragrance raw material.

[0052] Specifically, the raw materials include upper leaves, middle leaves and lower leaves, and the upper leaves ensure the aroma concentration of the fighting grass, with a ratio of 33-37% WT, 37-41% WT or 41-45% WT;

[0053] The middle leaves guarantee the aroma and taste of the grass, with a ratio of 33-37% WT, 37-41% WT or 41-45% WT;

[0054] The lower leaves are used to fill the formula and ensure the looseness of the raw materials, with a ratio of 13-17% WT, 17-21% WT or 21-25% WT.

[0055] Rehydration: Mix the prepared raw materials thoroughly and evenly, and use a roller to loosen and rehydrate them.

[0056] Specifically, the hot air temperature is 130°C, the return air temperature is 64-68°C, 68-72°C or 72-76°C, and the raw material temperature after rehumidification is controlled to be 54-58°C, 58-62°C or 62-66°C to further mix the raw materials evenly.

[0057] Specifically, after moisture regain, a mixed raw material with a first moisture content is obtained, and the first moisture content is 15%, 16% or 17%.

[0058] Step S2: adding an additive to the mixed raw material to obtain first shredded tobacco with a second moisture content;

[0059] Step S21: feeding the mixed raw materials into a shredder to obtain mixed shredded tobacco;

[0060] The mixed raw materials after rehydration are put into the shredder, and the shredding width is 1.5-1.7mm, 1.7-1.9mm or 1.9-2.1mm. The pressure of the shredder door is less than 5KN. After cutting, there is basically no shredded tobacco, the shredded tobacco is loose, and mixed shredded tobacco is obtained.

[0061] Step S22: adding additives to the mixed shredded tobacco and fermenting the mixture to obtain first shredded tobacco with a second moisture content;

[0062] Specifically, the additives include leather essence, rose essence, fructose and water, and the additives are mixed in a weight ratio of: leather essence: rose essence: fructose: water = 1.5:2:20:76.5 to form a mixed liquid.

[0063] Specifically, the mixed liquid is evenly applied to the mixed tobacco with the second moisture content according to an application ratio of 3-5%, 5-7% or 7-9% and an additive addition accuracy of ≤1%.

[0064] Specifically, the second moisture content is 18%, 19% or 20%.

[0065] Specifically, the mixed shredded tobacco is subjected to anaerobic fermentation to obtain the first shredded tobacco.

[0066] Specifically, without additional application of fermentation bacteria, the mixed tobacco is placed in a sealed container, such as a sealed box, a sealed cabinet, a sealed bag, etc., and fermented for 15 days at a constant temperature of 24-26°C, 26-28°C or 28-30°C. Finally, the mixed tobacco becomes darker in color and has a sweet aroma.

[0110] For the first layer (bottom), gently sprinkle a small amount of tobacco into the bowl and use your fingers or a tool to gently press it down to about 1 / 3 of the way up. Press firmly enough to "touch baby's skin" to ensure air circulation.

[0111] The second (middle) layer is filled with more tobacco and compressed slightly more firmly (similar to the force of "pressing a sponge"). This layer needs to be evenly distributed to avoid being too tight and causing poor ventilation.

[0112] Fill the third (top) layer with the remaining tobacco, pressing down slightly with your thumb or a pressing rod to ensure the top is flat and the fit is just right. The tobacco should be slightly springy and spring back when pressed.

[0113] The time for waking up the grass and filling the bucket is counted as the preparation time before smoking.

[0114] Comparative Example 2

[0115] The tobacco material used in Example 2 was allowed to rest in air at a relative moisture content of 60% and 25°C for 30 minutes to equilibrate the moisture content to 14%. The rested tobacco material was then filled into a pipe in a suitable manner:

[0116] For the first layer (bottom), gently sprinkle a small amount of tobacco into the bowl and use your fingers or a tool to gently press it down to about 1 / 3 of the way up. Press firmly enough to "touch baby's skin" to ensure air circulation.

[0117] The second (middle) layer is filled with more tobacco and compressed slightly more firmly (similar to the force of "pressing a sponge"). This layer needs to be evenly distributed to avoid being too tight and causing poor ventilation.

[0118] Fill the third (top) layer with the remaining tobacco, pressing down slightly with your thumb or a pressing rod to ensure the top is flat and the fit is just right. The tobacco should be slightly springy and spring back when pressed.

[0119] The time for waking up the grass and filling the bucket is counted as the preparation time before smoking.

[0120] Comparative Example 3

[0121] The tobacco material used in Example 3 was allowed to rest in air at a relative moisture content of 70% and 25°C for 30 minutes to balance the moisture content to 16%. The rested tobacco material was then filled into a pipe in a suitable manner:

[0122] For the first layer (bottom), gently sprinkle a small amount of tobacco into the bowl and use your fingers or a tool to gently press it down to about 1 / 3 of the way up. Press firmly enough to "touch baby's skin" to ensure air circulation.

[0123] The second (middle) layer is filled with more tobacco and compressed slightly more firmly (similar to the force of "pressing a sponge"). This layer needs to be evenly distributed to avoid being too tight and causing poor ventilation.

[0124] Fill the third (top) layer with the remaining tobacco, pressing down slightly with your thumb or a pressing rod to ensure the top is flat and the fit is just right. The tobacco should be slightly springy and spring back when pressed.

[0125] The time for waking up the grass and filling the bucket is counted as the preparation time before smoking.

[0126] Five novice pipe smokers smoked the pipe tobacco cartridges of Example 1 and the pipe tobacco of Comparative Example 1 with the same moisture content, and the smoking experience was summarized in Table 1.

[0127] Table 1 Suction evaluation of Example 1 and Comparative Example 1

[0128]

[0129] Five novice tobacco smokers smoked tobacco cartridges of Example 2 and tobacco from Comparative Example 2 with consistent moisture content, and their smoking experiences were summarized in Table 2.

[0130] Table 2 Puffing evaluation of pipe tobacco cartridges of Example 2 and Comparative Example 2

[0131]

[0132] Five novice pipe smokers smoked the pipe tobacco cartridges of Example 3 and the pipe tobacco of Comparative Example 3 with the same moisture content, and the smoking experience was summarized in Table 3.

[0133] Table 3 Suction evaluation of Example 3 and Comparative Example 3

[0134]

[0135] By controlling the moisture content, we compared the puffing experience and preparation time of pipe tobacco cartridges and pipe-filling with herb. It is obvious that the pipe-filling method involves complex processes such as waking up the herb and filling the pipe. Novice pipe smokers spend an average of 32-35 minutes preparing on this method. In addition, the filling effect directly affects the puffing experience. Therefore, the traditional pipe filling method is not friendly to novice pipe smokers.

[0136] On the contrary, the pipe tobacco cartridge only needs to be placed in the matching pipe combustion chamber, and the structure of the pipe tobacco cartridge makes the pipe burn smoothly, and there is basically no flameout phenomenon, which greatly reduces the difficulty of preparation work before smoking and improves the smoking experience of novice pipe smokers.

[0137] Five novice pipe smokers smoked the pipe tobacco cartridges of Examples 1 to 3, and their smoking experiences were summarized in Table 4.

[0138] Table 4 Suction evaluation of Example 4 and Comparative Example 4

[0139]

[0140]

[0141] By comparing the sensory experience of smoking pipe tobacco cartridges with different moisture contents, it can be found that when the moisture content of pipe tobacco cartridges is around 14%, the sensory quality is the best, the smoke is full, the aroma concentration is good, and the aftertaste is clean.

[0142] The cigarette cartridge eliminates the technical threshold for new pipe smokers to smoke pipes, and realizes the same timely inhalation as traditional cigarettes. The inhalation resistance is uniform and moderate during the inhalation process, and the combustion performance is good, which has obvious advantages over traditional pipe smoking.
