[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present disclosure claims priority to the application with the application number of 2024113079528 and the title of "Method for adjusting raw material formula of reconstituted tobacco prepared by roller method and application" filed with the China Patent Office on September 19, 2024, the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of tobacco manufacturing, in particular, to a method for adjusting raw material formula of reconstituted tobacco prepared by roller method and application. BACKGROUND

[0004] Low-temperature cigarettes are a new type of tobacco product, and its main feature is that through a special heating method, the tobacco raw material is heated to a certain temperature, so that the nicotine and flavor substances in the tobacco can be released for consumers to smoke. In this process, the processing method of the tobacco raw material has an important influence on the quality of low-temperature cigarettes. Reconstituted tobacco is one of the important raw materials of low-temperature cigarettes, so the quality of reconstituted tobacco directly affects the taste and quality of low-temperature cigarettes.

[0005] Roller method is one of the methods for preparing reconstituted tobacco. In the roller method, the raw materials are mixed into slurry material, then pressed into shape using a press roller, and then dried and cut for subsequent use. The main advantages of this method are compact equipment, small footprint, small investment scale, simple process and equipment, low energy consumption, and stable smoking quality. However, the slurry material has the risk of sticking to the roller during the process of pressing into shape by the press roller, or the reconstituted tobacco produced has high density, low filling value, low processing performance, and is prone to breakage during the cutting process. Especially for roller reconstituted tobacco used to prepare low-temperature cigarettes, a large amount of smoke-producing agent and additional flavorings need to be added to the raw materials, which puts higher requirements on the production process control of the roller method.

[0006] In view of this, the present disclosure is proposed. SUMMARY

[0007] The purpose of the present disclosure is to provide a method for adjusting the raw material formula of reconstituted tobacco prepared by roller method and application.

[0008] The present disclosure is implemented as follows:

[0009] In a first aspect, the present disclosure provides a method for adjusting the raw material formula of reconstituted tobacco prepared by roller method. The raw materials of the roller reconstituted tobacco include a powder system and a liquid system. The raw materials of the powder system include tobacco raw materials, and the raw materials of the liquid system include water, smoke-producing agent, glue and fiber.

[0010] mixing raw materials of the liquid material system to obtain a slurry, detecting viscosity of the slurry, and adjusting parameters of raw materials of the powder material system according to the viscosity of the slurry, the parameters of the raw materials of the powder material system including particle size of the tobacco raw material and / or sugar content of the tobacco raw material;

[0011] when the viscosity of the slurry is < 4000 mPa·s, decreasing the particle size of the tobacco raw material and / or increasing the sugar content of the tobacco raw material;

[0012] when the viscosity of the slurry is > 6000 mPa·s, increasing the particle size of the tobacco raw material and / or decreasing the sugar content of the tobacco raw material.

[0013] In a second aspect, the present disclosure provides application of the method according to any one of the preceding embodiments in preparation of reconstituted tobacco by a roller method.

[0014] The present disclosure has the following beneficial effects:

[0015] The present disclosure provides a raw material formula adjustment method and application in preparation of reconstituted tobacco by a roller method. By controlling viscosity of a slurry obtained after mixing raw materials of a liquid material system, particle size of a tobacco raw material and / or sugar content of the tobacco raw material are adjusted reversely to ensure that the slurry obtained after mixing of a powder material system and the liquid material system has relatively suitable properties and does not cause roller sticking. Meanwhile, the viscosity of the slurry is controlled in a range of 4000 mPa·s to 6000 mPa·s, which can ensure that the reconstituted tobacco obtained finally has suitable density, suitable filling value and good processing resistance, and can also reduce crushing of the reconstituted tobacco in a cutting process. DETAILED DESCRIPTION

[0016] The embodiments of the present disclosure will be described in detail below with reference to the examples, but those skilled in the art will understand that the following examples are only used to illustrate the present disclosure and should not be regarded as limiting the scope of the present disclosure. If specific conditions are not specified in the examples, conventional conditions or manufacturer recommended conditions are used. If the reagents or instruments used are not specified by the manufacturer, they are all conventional products that can be purchased on the market.

[0017] The process of preparing reconstituted tobacco by a roller method includes mixing raw materials to obtain a slurry, then conveying the slurry to a pressure roller to be pressed into a sheet, and then performing post-processing steps such as drying to obtain a sheet-shaped reconstituted tobacco. During the whole process, the proportion of each substance in the raw materials can be adjusted according to the performance requirements of the tobacco product to obtain a tobacco product with corresponding properties, so the method of preparing reconstituted tobacco by a roller method has relatively wide applicability.

[0018] However, due to the specific pressing step of the roller pressing method, the method also has limitations in the preparation of reconstituted tobacco, such as paste material sticking to the roller, or the reconstituted tobacco prepared has a larger density and poor processing resistance. At present, the problems in the preparation of reconstituted tobacco by the roller pressing method are often solved by experience, and there is no complete raw material formula adjustment method to guide, which increases the uncertainty of the operation process of the roller pressing method for preparing reconstituted tobacco, and is not conducive to the quality control of the product. Therefore, the inventors propose the following solutions.

[0019] In a first aspect, the present disclosure provides a raw material formula adjustment method for preparing reconstituted tobacco by a roller pressing method. The raw material of the roller pressing method reconstituted tobacco includes a powder system and a liquid system. The raw material of the powder system includes tobacco raw material, and the raw material of the liquid system includes water, a smoking agent, a glue and a fiber.

[0020] It should be noted that the raw material for preparing reconstituted tobacco by the roller pressing method includes but is not limited to the raw materials listed above. In actual production, the raw material for preparing reconstituted tobacco by the roller pressing method may also include fillers and flavors commonly used in cigarette products, and the above-mentioned raw materials are only listed in the present disclosure as raw materials that can affect the performance of the roller pressing method for preparing reconstituted tobacco.

[0021] After mixing the raw materials of the liquid system, a slurry is obtained. The viscosity of the slurry is detected, and the parameters of the raw materials of the powder system are adjusted according to the viscosity of the slurry. The parameters of the raw materials of the powder system include the particle size of the tobacco raw material and / or the sugar content of the tobacco raw material.

[0022] Since the slurry obtained by mixing the raw materials for preparing reconstituted tobacco by the roller pressing method is difficult to accurately detect its viscosity and flowability, this leads to the uncertainty of the roller pressing process and the uncertainty of the quality of the reconstituted tobacco finally obtained in the process of preparing reconstituted tobacco by the roller pressing method. Therefore, by detecting the viscosity of the slurry and adjusting the parameters of other raw materials according to the viscosity of the slurry, the applicant can better determine the raw material formula for preparing reconstituted tobacco by the roller pressing method, and ensure the smoothness of the roller pressing process and the better performance of the reconstituted tobacco.

[0023] The method provided by the present disclosure is based on the method for preparing reconstituted tobacco by the roller pressing method, so the method provided by the present disclosure is actually adjusting the formula of the raw material in reverse by detecting the process parameters and / or the parameters of the final product in the process of preparing reconstituted tobacco by the roller pressing method. Therefore, the steps of preparing reconstituted tobacco can refer to the existing technology for preparing reconstituted tobacco by the roller pressing method.

[0024] When the viscosity of the slurry is 4000 mPa·s-6000 mPa·s, the powder system and the liquid system are mixed at this time, and a slurry with moderate performance can be obtained.

[0025] When the viscosity of the slurry is < 4000 mPa·s, the particle size of the tobacco raw material can be reduced and / or the sugar content of the tobacco raw material can be increased based on the original raw material ratio to increase the viscosity of the slurry and obtain a slurry material with moderate performance.

[0026] When the viscosity of the slurry is > 6000 mPa·s, the particle size of the tobacco raw material can be increased and / or the sugar content of the tobacco raw material can be reduced based on the original raw material ratio to reduce the viscosity of the slurry and obtain a slurry material with moderate performance.

[0027] The "sugar content of the tobacco raw material" mentioned in the present disclosure refers to the mass percentage of sugar in the tobacco raw material.

[0028] In optional embodiments, increasing the particle size of the tobacco raw material refers to adjusting the particle size of the tobacco raw material to be > 100 mesh, and reducing the particle size of the tobacco raw material refers to adjusting the particle size of the tobacco raw material to be < 200 mesh.

[0029] Therefore, when the viscosity of the slurry is in a relatively suitable range, for example, the viscosity of the slurry is 4000 mPa·s to 6000 mPa·s, the particle size of the tobacco raw material should be 100 mesh to 200 mesh. Then, the particle size of the tobacco raw material is increased or reduced according to the change in the viscosity of the slurry to ensure that the slurry material with moderate performance can be obtained after mixing the raw materials.

[0030] Preferably, increasing the sugar content of the tobacco raw material refers to adjusting the sugar content of the tobacco raw material to be > 18%, and reducing the sugar content of the tobacco raw material refers to adjusting the sugar content of the tobacco raw material to be < 10%.

[0031] Therefore, when the viscosity of the slurry is in a relatively suitable range, for example, the viscosity of the slurry is 4000 mPa·s to 6000 mPa·s, the sugar content of the tobacco raw material is 10% to 18%. Then, the sugar content of the tobacco raw material is increased or reduced according to the change in the viscosity of the slurry to ensure that the slurry material with moderate performance can be obtained after mixing the raw materials.

[0032] The parameters of the powder system have a greater impact on the overall performance of the slurry material, but in addition, the parameters of each raw material in the liquid system also affect the overall performance of the slurry material, and further affect the performance of the reconstituted tobacco leaf.

[0033] In optional embodiments, the method further includes adjusting the parameters of the raw materials of the liquid system according to the viscosity of the slurry, and the parameters of the raw materials of the liquid system include at least one of the addition mass of the glue, the addition mass of the smoking agent, the addition mass of water, the addition mass of the fiber, and the length of the fiber.

[0034] The "addition mass" mentioned in the present disclosure refers to the mass percentage of each raw material in the total amount of raw materials, for example, the addition mass of the glue refers to the mass percentage of the glue in the total mass of raw materials.

[0035] When the viscosity of the slurry is < 4000 mPa-s, at least one of the following is increased: the added mass of the rubber material, the added mass of the smoke agent, the added mass of water, and the length of the fiber, and / or the added mass of the fiber is decreased.

[0036] When the viscosity of the slurry is > 6000 mPa-s, at least one of the following is increased: the added mass of the fiber, and / or the added mass of the rubber material, the added mass of the smoke agent, the added mass of water, and the length of the fiber is decreased.

[0037] In an optional embodiment, the increase in the added mass of the rubber material is > 6% of the adjusted added mass of the rubber material; the decrease in the added mass of the rubber material is < 2% of the adjusted added mass of the rubber material.

[0038] Therefore, when the viscosity of the slurry is in a more suitable range, for example, the viscosity of the slurry is 4000 mPa-s ~ 6000 mPa-s, the added mass of the rubber material should be 2% ~ 6%. Then, the added mass of the rubber material is increased or decreased according to the change in the viscosity of the slurry, so as to ensure that the mixed raw materials can obtain slurry materials with suitable performance.

[0039] Preferably, the increase in the added mass of the smoke agent is > 25% of the adjusted added mass of the smoke agent; the decrease in the added mass of the smoke agent is < 18% of the adjusted added mass of the smoke agent.

[0040] Therefore, when the viscosity of the slurry is in a more suitable range, for example, the viscosity of the slurry is 4000 mPa-s ~ 6000 mPa-s, the added mass of the smoke agent should be 18% ~ 25%. Then, the added mass of the smoke agent is increased or decreased according to the change in the viscosity of the slurry, so as to ensure that the mixed raw materials can obtain slurry materials with suitable performance.

[0041] Preferably, the increase in the added mass of water is > 25% of the adjusted added mass of water; the decrease in the added mass of water is < 15% of the adjusted added mass of water.

[0042] Therefore, when the viscosity of the slurry is in a more suitable range, for example, the viscosity of the slurry is 4000 mPa-s ~ 6000 mPa-s, the added mass of water should be 15% ~ 25%. Then, the added mass of water is increased or decreased according to the change in the viscosity of the slurry, so as to ensure that the mixed raw materials can obtain slurry materials with suitable performance.

[0043] Preferably, the increase in the added mass of the fiber is > 10% of the adjusted added mass of the fiber; the decrease in the added mass of the fiber is < 5% of the adjusted added mass of the fiber.

[0044] Therefore, when the viscosity of the slurry is in a more suitable range, for example, the viscosity of the slurry is 4000 mPa s-6000 mPa s, the added mass of the fiber should be 5%-10%. Then, according to the change of the viscosity of the slurry, the added mass of the fiber is increased or decreased to ensure that the mixed raw materials can obtain a slurry material with moderate performance.

[0045] Preferably, increasing the length of the fiber is adjusting the length of the fiber >2000 μm; decreasing the length of the fiber is adjusting the length of the fiber <1000 μm.

[0046] Therefore, when the viscosity of the slurry is in a more suitable range, for example, the viscosity of the slurry is 4000 mPa s-6000 mPa s, the length of the fiber should be 1000 μm-2000 μm. Then, according to the change of the viscosity of the slurry, the length of the fiber is increased or decreased to ensure that the mixed raw materials can obtain a slurry material with moderate performance.

[0047] Therefore, in some embodiments, the formula of the raw materials is changed according to the viscosity of the slurry, which can be seen from the adjustment mode in Table 1 as follows.

[0048] Table 1 Relationship between the viscosity of the slurry and the formula of the raw materials

[0049] In optional embodiments, in addition to adjusting the ratio of the raw materials by the viscosity of the slurry, the ratio of the raw materials can also be adjusted by the performance of the prepared reconstituted tobacco.

[0050] In optional embodiments, the reconstituted tobacco prepared by the rolling method is in the form of a paper sheet, and the added mass of the fiber and / or the thickness of the paper sheet-shaped reconstituted tobacco is adjusted according to the basis weight fluctuation of the paper sheet-shaped reconstituted tobacco.

[0051] The basis weight fluctuation refers to the difference in the mass per unit area of the paper over time in the paper production process. The greater the basis weight fluctuation, the worse the uniformity of the paper, and therefore the direction of adjusting the raw materials is determined by detecting the basis weight fluctuation of the reconstituted tobacco.

[0052] When the absolute value of the basis weight fluctuation is >10 g / m 2 , the thickness of the reconstituted tobacco and / or the added mass of the fiber is increased to ensure that the pressing process of the slurry material is more uniform in the rolling process.

[0053] Further, according to whether the slurry material sticks to the roller in the pressing process, the added mass of the glue can be adjusted. When the slurry material sticks to the roller, the added mass of the glue is reduced; when the slurry material does not stick to the roller, the added mass of the glue is increased.

[0054] In optional embodiments, the particle size of the tobacco raw material and / or the added mass of the fiber is also adjusted according to the bulkiness of the paper sheet-shaped reconstituted tobacco.

[0055] When the porosity is <0.9cm 3 When the fiber content is >1.1 g / m, increase the added fiber mass and / or reduce the particle size of the tobacco raw material; when the bulk thickness is >1.1 g / m 2 At the same time, reduce the amount of fiber added and / or increase the particle size of the tobacco raw materials.

[0056] Therefore, the suitable range for porosity is 0.9 cm. 3 / g~1.1g / m 2 After adjusting the raw material formula using the aforementioned method, the reconstituted tobacco leaves obtained had a bulk thickness of 0.9 cm. 3 / g~1.1g / m 2 When the density of the reconstituted tobacco leaves is within the specified range, there is no need to adjust the raw material ratio. However, when the density of the reconstituted tobacco leaves is higher or lower than the specified range, it is necessary to adjust the particle size of the tobacco raw materials and / or the quality of fiber addition accordingly.

[0057] In an optional embodiment, the addition of the rubber compound and / or the addition of fibers is further adjusted according to the tensile strength of the reconstituted tobacco prepared by the roll pressing method.

[0058] When the tensile strength is <200 N / m, increase the amount of rubber compound and / or fiber added; when the tensile strength is >400 N / m, decrease the amount of rubber compound and / or fiber added.

[0059] Therefore, the suitable range for tensile strength is 200 N / m to 400 N / m. When the tensile strength of the reconstituted tobacco leaves is within the range of 200 N / m to 400 N / m after adjusting the raw material formula using the aforementioned method, it is not necessary to adjust the raw material ratio. However, when the tensile strength of the reconstituted tobacco leaves is higher or lower than the above range, it is necessary to adjust the amount of rubber added and / or the amount of fiber added accordingly.

[0060] In an optional embodiment, the addition of a smoke-generating agent is further adjusted according to the amount of smoke produced by the reconstituted tobacco prepared by the rolling process.

[0061] When the smoke content is <40%, increase the amount of smoke generator added; when the tensile strength is >400 N / m, decrease the amount of smoke generator added.

[0062] In an optional embodiment, the tobacco raw material is tobacco powder; in other embodiments, the tobacco raw material may also be other forms of tobacco.

[0063] Smoke-generating agents include, but are not limited to, at least one of glycerin, propylene glycol, and glycerol.

[0064] The adhesive includes, but is not limited to, at least one of sodium carboxymethyl cellulose, xanthan gum, or cellulose gum.

[0065] The fibers include, but are not limited to, flax pulp fibers and / or broadleaf wood pulp fibers.

[0066] In a second aspect, the present disclosure provides a method according to any of the preceding embodiments for use in the preparation of reconstituted tobacco leaves by a roll press method.

[0067] For example, the method can be applied to an industrial production line for the preparation of reconstituted tobacco leaves by a roll press method, to regulate the raw material formula through equipment control, so as to obtain reconstituted tobacco leaves with better performance and more stable production quality.

[0068] Example 1

[0069] The present embodiment provides a raw material formula adjustment method for the preparation of reconstituted tobacco leaves by a roll press method, which is applied in the process of the preparation of reconstituted tobacco leaves by a roll press method.

[0070] S01, raw material selection

[0071] The tobacco raw material is tobacco powder, the sugar content of the tobacco powder is 12%, and the particle size is 120 mesh.

[0072] The smoking agent is glycerol, and the addition amount of glycerol is 20%.

[0073] The sizing agent is sodium carboxymethyl cellulose, and the addition amount of the sizing agent is 3%.

[0074] The fiber is flax pulp fiber, the addition amount of the fiber is 8%, and the average length is 800 um.

[0075] The addition amount of water is 20%, and the use of other key auxiliaries is adjusted according to actual needs.

[0076] S02, the tobacco powder and other solid powders (such as additional fillers and powdered flavors, etc.) are sequentially added under the condition that the stirrer is opened and the stirrer is stirring, and after the addition is completed, the stirring is continued for 15 min to ensure that the powder system is uniformly mixed.

[0077] S03, first, the water, glycerol, sizing liquid and other liquid auxiliaries are uniformly mixed, and then an emulsifier is used for emulsification and stirring at a speed of 10000 rpm. During the emulsification process, the fiber is gradually added, and after stirring, the sizing agent is gradually added for emulsification, emulsified for 3 min, and the liquid material is prepared.

[0078] The viscosity of the sample detection liquid is 3890 mPa·s, so the amount of sizing agent sodium carboxymethyl cellulose is adjusted from 2% to 3% in this embodiment, and then further emulsification and shearing operation is performed, and the viscosity of the liquid material is detected again. 4500 mPa·s, that is, the preparation of the liquid material is completed.

[0079] S04. The powder system of S02 and S03 and the liquid are mixed evenly to obtain a slurry. The slurry is then pressed by rollers to form reconstituted tobacco leaves. The reconstituted tobacco leaves are sent for testing, and the results are shown in Table 2.

[0080] The tensile strength was measured at 360 N / m, and the bulk density was measured at 1.030 cm. 3 / g; the smoke concentration was 42.1%; the quantitative fluctuation was ≤8g / m³. 2 .

[0081] Table 2 Performance of Reconstituted Tobacco

[0082] According to the performance test results in Table 2, the method of reverse regulation of the raw material formula of reconstituted tobacco in this embodiment can obtain reconstituted tobacco with better performance. Moreover, the method is simple and easy to implement, has good adaptability, produces reconstituted tobacco with high consistency, improves production efficiency, and makes the production process more stable.

[0083] Comparative Example 1

[0084] This comparative example provides a method for adjusting the raw material formulation for preparing reconstituted tobacco using the roll pressing method, which is applied in the process of preparing reconstituted tobacco using the roll pressing method.

[0085] The difference between this comparative example and Example 1 is that the sugar content of the tobacco powder is 19% and the particle size is 200 mesh. To prevent the viscosity of the slurry from being too high, powdered fiber is used. The average fiber length is 500 μm, and the fiber addition mass is 8%. Because powdered fiber is used, the fiber is mixed with the tobacco powder to obtain a powder system, while no fiber is added to the liquid system.

[0086] The liquid mixture contained 8% water, 25% glycerol, and 4% adhesive. The final liquid mixture had a viscosity of 10,000 mPa·s.

[0087] The slurry obtained by mixing the above-mentioned powder system and liquid has a high viscosity during the pressing process, which causes the rollers to stick and the sample preparation process to be unstable. In addition, the wet strength of the slurry is low, and the equipment cannot be operated continuously. Therefore, only a small amount of reconstituted tobacco leaves were prepared for evaluation and testing.

[0088] The test results of this comparative example are shown in Table 3. The test method is described in Example 1.

[0089] Table 3 Performance of Reconstituted Tobacco

[0090] According to the performance test results in Table 3, the smoke powder sugar content selected in Comparative Example 1 is relatively high, although the powder fiber is used to increase the mass of the powder system, the added mass of water in the liquid material is relatively low, and the added mass of glycerol is relatively high, the tensile strength and basis weight of the reconstituted tobacco leaf prepared do not meet the requirements, and the quality of the reconstituted tobacco leaf is poor.

[0091] Example 2

[0092] The present embodiment provides a raw material formula adjustment method for preparing reconstituted tobacco leaf by rolling method, which is applied to the process of preparing reconstituted tobacco leaf by rolling method.

[0093] The present comparative example is based on the scheme of Comparative Example 1, and the raw material formula is adjusted according to the method provided in the present disclosure, which includes selecting a smoke powder with a particle size of 120 mesh and a sugar content of 19% on the basis of Comparative Example 1; the average length of the fiber is 1100 um, and a powder system is obtained.

[0094] The added mass of water in the liquid material system is 12%, and the added mass of glycerol is 21%, and the viscosity of the obtained material liquid is 7540 mPa·s.

[0095] The slurry material obtained by mixing the above powder system and the material liquid is pressed and formed, and it is found that the viscosity of the slurry material is significantly reduced compared with Comparative Example 1, the processing performance is improved, and the equipment can be continuously and stably operated. The reconstituted tobacco leaf prepared is detected by the same method as in Example 1, and the results are shown in Table 4.

[0096] Table 4 Performance of reconstituted tobacco leaf

[0097] According to the performance test results in Table 4, the raw material ratio of Comparative Example 1 is adjusted according to the method of the present disclosure in Example 2, and the quality of the reconstituted tobacco leaf prepared is obviously better than that of Comparative Example 1, and the improvement effect is obvious. However, since the viscosity of the material liquid and the sugar content of the smoke powder are still insufficient, the bulkiness of the obtained reconstituted tobacco leaf still has room for further adjustment.

[0098] From the adjustment process of Comparative Example 1 and Example 2, it can be seen that the method provided in the present disclosure can significantly improve the quality of the reconstituted tobacco leaf prepared by rolling method, and the method provides a basis for adjusting the raw material formula for preparing reconstituted tobacco leaf by rolling method, which is beneficial to improve the production efficiency and the stability of the product produced.

[0099] The raw material formula adjustment method and application for preparing reconstituted tobacco leaf by rolling method provided in the present disclosure at least have the following advantages:

[0100] 1、The present disclosure not only evaluates the sugar content and particle size of tobacco raw materials, the added quality of smoke agents and water, etc., but also comprehensively evaluates the length and added quality of fibers, so as to more comprehensively and accurately reflect the real situation of the pulp material, thereby effectively improving the production efficiency, optimizing the production process, and also being beneficial to improving the quality stability and consistency of the product.

[0101] 2、The present disclosure quantitatively evaluates the viscosity of the slurry, combines the comprehensive evaluation of the powder system, forms a comprehensive quality evaluation system, and adjusts the formula of the raw material through the feedback of the quality evaluation result, so as to more accurately control the pulping process and improve the product quality.

[0102] 3、The adjustment method of the present disclosure is not only suitable for the raw material system of the low-temperature smoke special roller pressing method reconstituted tobacco leaf, but also suitable for other types of tobacco products or similar pulping processes in other fields, has strong adaptability and wide application prospect, mainly screens the core parameters that have greater influence on the product quality, and performs quantitative evaluation and optimization adjustment.

[0103] The above is only the preferred embodiment of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
