[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] In the following text, the terms "comprising," "having," and their cognates, which may be used in various embodiments of this application, are intended only to indicate a particular feature, number, step, operation, element, component, or combination thereof, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations thereof, or adding the possibility of one or more combinations thereof. Furthermore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0021] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] The optimization method of the flavor atomizing device will be explained below with reference to some specific embodiments.

[0024] Figure 1A flowchart illustrating an optimization method for a fragrance atomizing device according to an embodiment of this application is shown. Exemplarily, the optimization method for the fragrance atomizing device includes the following steps: S110, measuring fragrance atomization data under multiple fragrance atomization conditions in the fragrance atomization device.

[0025] In this embodiment, the fragrance atomizing device includes a nozzle, a gas source, and a liquid delivery system. The gas inlet of the nozzle is connected to the gas source, and the liquid inlet of the nozzle is connected to the liquid delivery system. In this embodiment, the nozzle serves as the atomization execution terminal, where the compressed gas (from the gas source) and the fragrance liquid (from the liquid delivery system) are mixed, sheared, and exchanged energy at its internal / exit points, ultimately completing atomization. The gas source provides a controllable compressed gas pressure to drive the gas, and the liquid delivery system provides an adjustable fragrance liquid flow rate.

[0026] Exemplary, the fragrance atomization conditions include the compressed gas pressure supplied to the nozzle and the fragrance liquid flow rate. A series of representative calibration points can be set according to the nozzle's design conditions or the desired optimization range. Each calibration point is uniquely determined by two parameters: compressed gas pressure and fragrance liquid flow rate. The pressure and flow rate ranges should cover the ranges likely used in actual production. The calibration medium uses the fragrance actually used in production, or a simulated medium that can replace the fragrance after verification of key physical properties such as viscosity and surface tension, such as a glycerol aqueous solution of a specific concentration.

[0027] In one embodiment, such as Figure 2 As shown, the fragrance atomization data includes droplet size data, droplet velocity data, and spray angle under various fragrance atomization conditions. For each set fragrance atomization condition, the fragrance atomization data is obtained by following these steps: S111, acquire droplet size data measured by the particle size analyzer at a first preset distance from the nozzle; the droplet size data includes the size of each droplet in the plane at a first preset distance from the nozzle in each fragrance atomization condition.

[0028] In one embodiment, a particle size analyzer is used to measure the droplet size distribution. For example, the particle size analyzer can be a laser particle size analyzer, with its laser emitting and receiving units arranged on a horizontal plane at a specified distance below the nozzle. The gas source and liquid delivery system are turned on and stabilized to the set operating conditions. The particle size analyzer is started, and measurements are taken at a first preset distance (preferably 500 mm) directly below the nozzle. Data is continuously collected until a stable result is obtained, and the droplet size under this operating condition is recorded.

[0029] S112, acquire droplet velocity data measured by the velocity measuring device at multiple second preset distances from the nozzle; the droplet velocity data includes the velocity of each droplet in a plane at a second preset distance from the nozzle in each fragrance atomization condition.

[0030] In one embodiment, the velocity measuring device can use a phase Doppler analyzer (PDA) or a similar velocity measuring device to maintain stable operating conditions. The second preset distance is a set of fixed axial position coordinate values ​​set by the velocity measuring device in space, with the nozzle outlet as the origin along the central axis of the spray.

[0031] In this embodiment, a PDA probe can be used to select a series of measurement points along the spray centerline and in the direction perpendicular to the centerline in the spatial coordinate system with the nozzle outlet as the origin. For example, a point can be taken at a preset interval along the centerline, and multiple points can be taken in the plane passing through the point and perpendicular to the centerline. For example, multiple points can be taken evenly in the direction line perpendicular to the centerline. The average velocity magnitude and direction of the droplets at each point are measured and recorded, and a velocity field distribution map is drawn.

[0032] In this embodiment, the detection and testing of the three core physical indicators of particle size, velocity, and spray angle are integrated, which can comprehensively evaluate the atomization effect, improve the accuracy of flavor atomization device optimization, and obtain objective and quantitative data by using precision instruments such as laser particle size analyzer, PDA, and high-speed camera, thus avoiding the subjectivity of experience-based judgment.

[0033] S113, acquire the spray boundary image of the nozzle, determine the spray angle based on the spray boundary image, and obtain spray angle data including the spray angle in each fragrance atomization condition.

[0034] In one embodiment, an image of the spray boundary is captured using a high-speed camera or SLR camera with a background light source, and the spray angle is measured. In this embodiment, while maintaining stable operating conditions, the high-speed camera is used in a darkroom environment to capture images perpendicular to the main spray plane, obtaining a clear image of the spray boundary. The image can be imported into image processing software, and the spray angle is measured and calculated based on a calibrated scale. Figure 3 The curves showing the relationship between spray angle and pressure and flow rate are presented. Figure 3 It can be seen that the spray angle increases slightly with the flow rate when the pressure is constant, and decreases with the pressure when the flow rate is constant.

[0035] S120 determines the median droplet size, spray angle, and droplet velocity at the target horizontal plane under various fragrance atomization conditions based on fragrance atomization data.

[0036] In one embodiment, the droplet size data in each fragrance atomization condition are sorted to obtain the median droplet size in each fragrance atomization condition; the droplet velocity data in the plane at a target preset distance from the nozzle in each fragrance atomization condition is taken as the droplet velocity in the target horizontal plane; and the spray angle data is taken as the spray angle in each fragrance atomization condition.

[0037] In this embodiment, after sorting the droplet size data from smallest to largest, the droplet size corresponding to the 10% cumulative distribution (D10) can be determined, representing the boundary of fine particles in the particle group; 10% of the particles are finer than this. The droplet size corresponding to the 50% cumulative distribution represents the medium particle size level of the particle group, i.e., the median droplet size (D50). The droplet size corresponding to the 90% cumulative distribution (D90) can also be determined, representing the boundary of coarse particles in the particle group; 90% of the particles are finer than this. A particle size distribution map can also be obtained based on the spatial distribution of each droplet size, allowing for a more intuitive observation of the particle size distribution. The target preset distance can be set to 500mm; the droplet velocity at the target preset distance plane determines the momentum and penetration ability of the droplets when they impact the tobacco. Figure 4 As shown, this is a droplet velocity distribution diagram in a plane at a target preset distance. In the plane at the target preset distance, the droplet velocity distribution has the characteristics of being high in the center and low at the edges.

[0038] like Figure 5 The figure shows the particle size distribution curves at different fragrance liquid flow rates and a compressed gas pressure of 0.22 MPa. Figure 6 The figure shows the particle size distribution curves at different fragrance liquid flow rates under a compressed gas pressure of 0.3 MPa. Figure 7 The figure shows the particle size distribution curves at different fragrance liquid flow rates and compressed gas pressures of 0.5 MPa. Figure 5 , 6 As shown in Figure 7, D50 decreases with increasing pressure and increases with increasing flow rate. Under operating conditions (0.22 MPa, 50-78 kg / h), D50 ranges from 65.2 to 73.9 μm.

[0039] S130, based on the first comparison result between the median droplet size and the target droplet size range, the second comparison result between the spray angle and the target spray angle range, and the third comparison result between the droplet velocity and the target velocity range, the optimal fragrance atomization condition range is determined.

[0040] In one embodiment, based on the first comparison result, the second comparison result, and the third comparison result, a set of fragrance atomization conditions that simultaneously satisfy the target particle size range, the target spray angle range, and the target velocity range is selected; the compressed gas pressure and fragrance liquid flow rate corresponding to the set of fragrance atomization conditions are taken as the optimal fragrance atomization condition interval. The target particle size range, the target spray angle range, and the target velocity range can be set according to actual conditions. For example, the target particle size range is set to 60~80μm, the target spray angle range is set to 30°~180°, and the target velocity range is set to 2-4m / s.

[0041] In this embodiment, for all fragrance atomization conditions, the median droplet size, spray angle, and droplet velocity are checked one by one to see if they simultaneously meet the preset target range. The set of operating points that simultaneously meet the above three indicators is selected to obtain the optimal fragrance atomization condition range. Operating the nozzle within this range can achieve the optimal synergy between atomization sufficiency, coverage width, and penetration, significantly improving fragrance uniformity and fragrance utilization rate.

[0042] For example, in one embodiment, during the calibration of a gas-liquid two-phase flow external mixing nozzle, tests were conducted at 20 operating points (pressure: 0.22, 0.30, 0.40, 0.50 MPa; flow rate: 40, 50, 60, 70, 80 kg / h). It was found that under the parameter combination of pressure 0.22-0.30 MPa and flow rate 70-80 kg / h: the median droplet size was approximately 65.2-73.9 μm, which met the desired moderate droplet size; the spray angle was relatively large, which was beneficial for uniform coverage; and the droplet velocity was moderate. This region was determined to be the optimal fragrance atomization operating condition range.

[0043] S140, based on the optimal fragrance atomization condition range, the fragrance atomization device is operated under the optimal fragrance atomization condition.

[0044] In one embodiment, during the operation of the fragrance atomizing device, the optimal fragrance atomizing condition range is used as the target control range and connected to the production control system. This allows the compressed gas pressure supplied by the gas source to the nozzle to be controlled within the optimal fragrance atomizing condition range, and the flow rate of the fragrance liquid supplied by the liquid delivery system to the nozzle to be controlled within the optimal fragrance atomizing condition range, so that the fragrance atomizing device operates under the optimal fragrance atomizing condition.

[0045] In one embodiment, under the condition that the fragrance atomizing device is operating in the optimal fragrance atomizing conditions, the contraction angle of the nozzle is adjusted to adjust the coverage area of ​​the fragrance sprayed by the fragrance atomizing device.

[0046] In this embodiment, if the test finds that the spray angle is too small (e.g., <30°), which is the main reason for the incomplete coverage of the tobacco shreds, it is recommended to increase the nozzle outlet contraction angle. For example, by designing the nozzle contraction angle from 20° to 45°, the spray angle of the new nozzle is increased from 26.98° to 31.8° under the same operating conditions.

[0047] In another embodiment, the compressed gas pressure and the fragrance liquid flow rate are adjusted within the optimal fragrance atomization condition range to adjust the droplet size, spray angle, or droplet velocity.

[0048] In this embodiment, if the median droplet size is too large (e.g., >80μm), it may affect the absorption uniformity. Therefore, it is recommended to optimize the gas-liquid two-phase mixing structure to enhance the shearing and fragmentation effect. For example, based on the performance at each operating point, if it is necessary to reduce the droplet size, the gas path pressure can be increased by 0.05-0.10MPa or the flow rate can be reduced by 5-10kg / h within the optimal fragrance atomization operating range. If, according to the droplet velocity measured by the PDA, the velocity distribution is uneven or the overall velocity does not meet the penetration requirements, it is recommended to adjust the design of the nozzle or airflow channel, increasing the gas path pressure by 0.05-0.10MPa or the flow rate by 5-10kg / h within the optimal fragrance atomization operating range. If it is necessary to increase the spray angle, the flow rate can be moderately increased or the pressure slightly decreased, provided that the droplet size is not significantly increased.

[0049] Optionally, the flavoring operating parameters can be expanded by combining the actual airflow environment parameters of the production line. The airflow environment parameters include, but are not limited to, ejector pressure, dehumidifying fan frequency, and drum speed. By combining the above airflow environment parameters with the original flavoring atomization conditions of the nozzle, the flavoring atomization data can be further measured to determine the optimal flavoring atomization condition range. This can effectively optimize the flavoring atomization device and improve the uniformity and effective utilization rate of the tobacco.

[0050] In one embodiment, this application is not only applicable to the performance evaluation and process optimization of a single nozzle, but can also be extended to the comparative analysis of different nozzle models, providing a quantitative basis for equipment selection, quality monitoring, and continuous improvement. By systematically verifying multiple nozzle models under the same operating conditions, fragrance atomization data is obtained and compared with the target set range to determine the relationship between nozzle model and fragrance atomization data. For example, the larger the nozzle angle, the larger the spray angle; the nozzle angle corresponding to uniform droplet velocity distribution; the nozzle angle corresponding to larger droplet velocity; and the appropriate nozzle model is selected based on the relationship between nozzle model and fragrance atomization data.

[0051] When used in wide-width flavoring scenarios, where the tobacco conveyor belt is wide or large-area coverage is required, nozzles with a spray angle >35° should be selected to reduce flavoring blind spots and improve lateral uniformity. For scenarios requiring high uniformity, especially for high-end cigarette brands with high requirements for aroma consistency, nozzles with a median droplet size controlled within the range of 60–70 μm and uniform droplet velocity distribution are recommended to ensure fine atomization and stable deposition. For scenarios requiring high-efficiency penetration, such as dense tobacco bundles or high-speed production lines, it is necessary to enhance droplet kinetic energy to improve penetration. It is recommended to select nozzles with an average droplet velocity of 3–4 m / s at the target plane and a moderate droplet size (65~75 μm) to balance penetration and adhesion efficiency. The above selection criteria are based on actual measurement data, avoiding the blindness of traditional trial-and-error replacements and significantly improving the scientific and targeted nature of equipment configuration. Moreover, the above methods can not only be used for performance evaluation of existing nozzles but also provide key testing and verification methods for the research and development of new nozzles.

[0052] For example, in one embodiment, based on fragrance atomization data (such as...) Figure 3 , 4 As shown in Figures 5, 6, and 7, this nozzle exhibits a moderate droplet size (D50 approximately 70 μm) under the current primary operating conditions, but its spray angle is relatively small (<32°), potentially leading to incomplete coverage of the tobacco spray surface. Recommendation: To improve uniformity, prioritize selecting an operating point that moderately increases the spray angle (e.g., slightly increasing the flow rate) while ensuring no significant increase in droplet size, or consider improving the nozzle structure to widen the spray angle. Optimal operating range recommendation: For scenarios prioritizing uniformity, a recommended operating range is [insert range here]. The spray angle is relatively large within this range. Calibration report output: A complete report containing all data, pattern analysis, and optimization recommendations.

[0053] In this embodiment, this application can not only scientifically determine the optimal flavor atomization condition range, but also provide quantitative data support for nozzle structure improvement and production optimization. Moreover, based on actual measurement data, it has clear guidance and operability, which helps to achieve precise control and continuous optimization of the tobacco flavoring process.

[0055] The data processing module 220 is used to determine the median droplet size, spray angle, and droplet velocity at the target horizontal plane in various fragrance atomization conditions based on fragrance atomization data.
