[0002] In tobacco product production, the application of flavoring material is crucial for improving product taste and aroma. However, the existing technology has significant limitations in handling flavoring material atomization. Current production processes usually apply a fixed set of parameters to all product specifications, failing to fully consider the impact of flavoring material liquid density, viscosity and other physical properties on atomization effects in actual production, leading to increased quality risks of uneven atomization among different products. In addition, traditional supply systems lack mode control of the entire process of flavoring material liquid supply, and lower automation level and imperfect cleaning procedures increase the complexity of flavoring material liquid supply operations and maintenance costs.

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

[0019] A syrup supply device for a gum atomization test platform mainly consists of a gum syrup storage unit 1 and a pipeline supply system, wherein the pipeline supply system is also connected to a compressed air supply pipeline and a steam generator supply pipeline.

[0020] like Figure 1 As shown, the liquid storage unit 1 stores the liquid in the liquid tank 101 and is connected to the pipeline of the pipeline supply system.

[0021] The pipeline feeding system includes components such as density sensor 2, viscometer 3, gear pump 4, safety valve 5, pneumatic shut-off valve 6, pneumatic three-way valve 7, ball valve 8, liquid check valve 9, flow controller 10, temperature sensor 11, pressure sensor 12, nozzle 13, angle adjuster 14, infusion pipe 15, return pipe 16, and connecting pipe 17.

[0022] The infusion tube 15 and the upper end of the gum liquid storage unit 1 are provided with a return tube 16, which is connected to the infusion tube 15 through a connecting tube 17. The pipeline is made of transparent reinforced material, and stainless steel corrugated pipes are added at key bends to compensate for thermal expansion. Sealing gaskets are embedded at the flange connections to ensure airtightness. The overall structure takes into account both flow stability and ease of cleaning.

[0023] A pneumatic shut-off valve 6, a density sensor 2, a viscometer 3, and a gear pump 4 are sequentially installed on the delivery pipe 15 at the lower end of the gum syrup storage unit 1. The density sensor 2 is in contact with the gum syrup to monitor its density changes in real time. The viscometer 3 is located on the same section of the delivery pipe 15 and is fixed by a mounting bracket to detect the viscosity of the gum syrup. The gear pump 4 is installed in the delivery pipe 15 downstream of the viscometer 3. The gear pump 4 is connected to the nozzle 13 via the delivery pipe 15 and is responsible for transporting the gum syrup from the liquid tank 101 to the nozzle 13. A safety valve 5 is installed on the connecting pipe 17 at the pump outlet to protect the system from overpressure damage. Some sections of the pipeline are made of reinforced transparent material to facilitate observation of the gum syrup flow and ensure visual inspection after cleaning.

[0024] A pressure sensor 12 is installed on the connecting pipe 17 below the safety valve 5. Pneumatic shut-off valves 6 are also installed on the inlet pipe 15 and return pipe 16 near the nozzle 13. Pneumatic three-way valves 7 are located on both sides of the flow controller 10 on the inlet pipe 15. The pneumatic shut-off valves 6 are distributed at key nodes from downstream of the gear pump 4 to the front end of the nozzle 13, used to control the material flow path. The pneumatic three-way valves 7 are located on the pipeline at the front end of the nozzle 13, enabling the selection and switching between air pressure and steam sources.

[0025] From the end where the infusion pipe 15 connects to the return pipe 16 to the pneumatic three-way valve 7, a temperature sensor 11 and a ball valve 8 are sequentially installed. A pressure sensor 12 is installed on the ball valve 8 to monitor changes in the temperature and injection pressure of the flavoring liquid. These sensors are fixed by an embedded mounting method to reduce external interference and ensure data accuracy.

[0026] Two liquid check valves 9 and a pressure sensor 12 are sequentially installed on the return pipe 16 in the direction away from the gum liquid storage unit 1. The two liquid check valves 9 are set in opposite directions to prevent the gum liquid from flowing back.

[0027] The flow controller 10 is located on the infusion pipe 15 upstream of the gear pump 4. By adjusting the speed of the gear pump 4, the consistency of each spray from the nozzle 13 is ensured.

[0028] In one embodiment, such as Figures 2-4 As shown, the gum liquid storage unit 1 includes components such as a liquid tank 101, an electric heating element 110, a stirring motor 111, an upper stirring arm 117, a lower stirring arm 118, and an ultrasonic vibration plate 119.

[0029] The liquid storage unit 1 for the gum syrup adopts a double-layer structure design. The inner and outer layers can be made of SUS316L stainless steel, and the interlayer between the inner and outer layers is filled with a high-efficiency heat-conducting medium. In this embodiment, a high-efficiency heat-conducting grease can be used to achieve uniform heating. The liquid storage unit 101 has a heat-conducting medium inlet 102 at the top and a heat-conducting medium outlet 103 at the bottom. The heat-conducting medium inlet 102 and the heat-conducting medium outlet 103 are connected and equipped with quick connectors and sealing gaskets to form a circulation path. An oil temperature sensor 104 is installed on the outer wall of the tank near the heat-conducting oil outlet to monitor the temperature change of the heat-conducting oil, thus forming a circulation loop for the heat-conducting medium. Uniform heating is achieved through the circulation pipelines at the top and bottom.

[0030] A stirring motor 111 is fixedly installed on the top of the liquid tank 101 to drive a stirring shaft that runs vertically through the tank. The upper section of the stirring shaft is connected to a straight blade of the upper stirring arm 117. The straight blade rotates close to the top of the tank to ensure uniform mixing of the surface liquid. The lower section of the stirring shaft is connected to a multi-stage U-shaped blade of the lower stirring arm 118. The multi-stage U-shaped blade has an air chamber inside and is connected to several nozzles on its surface. The stirring shaft has an internal air passage to deliver compressed air to the lower multi-stage U-shaped blade and spray it out through the nozzles. The intermittent jetting creates a vortex airflow, which effectively prevents the deposition of high-viscosity liquid. It can also be connected to compressed air or clean water and compressed air for deep cleaning when needed.

[0031] An ultrasonic vibration plate 119 is embedded in the inner wall of the bottom of the liquid tank 101. The ultrasonic vibration plate 119 contains multiple ceramic ultrasonic guide plates for heating, stirring, and ultrasonic vibration. High-frequency vibration eliminates air bubbles in the liquid and assists in removing residues in cleaning mode. This design ensures temperature stability and mixing uniformity of the gum liquid during storage and processing, while also improving cleaning convenience.

[0032] A transparent observation window 112 and a liquid level sensor are installed on the side wall of the liquid tank 101 to monitor the liquid status and capacity in real time. The external heat transfer oil circulation system and the temperature and humidity sensor 113 work together to ensure the liquid temperature is stable.

[0033] The electric heating element 110 is embedded in the jacket and distributed around it to ensure uniform heating of the heat transfer medium and improve heating efficiency. An oil temperature sensor 104 for monitoring the temperature of the heat transfer medium is installed in the jacket, or it can be installed near the heat transfer oil outlet. Its function is to monitor changes in the temperature of the heat transfer oil.

[0034] The liquid tank 101 has a level gauge connection port 105 on its side wall, and a level gauge 106 for monitoring the liquid volume is installed inside the level gauge connection port 105. The top of the liquid tank 101 has a return port 114, a liquid inlet 115, and a vent 116. The return port 114 is connected to the return pipe 16 to receive the return liquid from the pipeline supply system. The liquid inlet 115 is connected to the external supply pipe and is equipped with a filter screen to prevent impurities from entering. The vent 116 is located at the highest point of the top of the liquid tank 101 to expel excess gas and is equipped with a dust cap. The bottom of the liquid tank 101 is connected to a drain pipe 109 and a liquid outlet 108, and the liquid outlet 108 is connected to the delivery pipe 15. The bottom of the liquid tank 101 also has a drain port 107, equipped with a manual valve to control the discharge. A temperature and humidity sensor 113 for monitoring the liquid temperature and the humidity inside the tank is embedded in the lower part of the inner wall of the tank and directly contacts the gum liquid.

[0035] Reference Figure 5 In this embodiment, the nozzle 13 is provided with two inlet ends. One inlet end is configured as a liquid inlet 134 to provide a liquid source, and the other inlet end is configured as an air inlet 135 to provide an air source.

[0036] The nozzle 13 has multiple atomizing chambers from the inlet to the outlet, namely a primary mechanical impact chamber 131, a secondary vortex shearing chamber 132, and a tertiary array of multi-hole nozzles 133. The primary chamber disperses the liquid through mechanical impact, the secondary chamber uses spiral guide vanes to form vortex shearing to refine the droplets, and the tertiary chamber outputs a uniform atomized flow through the multi-hole nozzle array. The liquid inlet 134 is connected to the primary mechanical impact chamber 131, and an angle adjuster 14 is connected to the outside of the nozzle 13.

[0037] The nozzle 13 is designed to support either compressed air or steam injection. Air is supplied to the nozzle 13 via an air inlet 135, located on one side of the nozzle 13. A liquid inlet 134, providing the liquid source, is positioned at the center of the bottom of the nozzle 13. The two are connected via an internal channel to ensure thorough mixing of the gum liquid and the gas. An angle adjuster 14 is installed on the outside of the nozzle 13, allowing users to adjust the spray angle according to specific needs. The nozzle 13 is connected to both the air and liquid sources via quick-connect couplings for easy disassembly and maintenance. The nozzle 13 employs a multi-stage atomization design and flexible switching between compressed air and steam injection modes to adapt to different liquid characteristics and process requirements.

[0038] In one embodiment, a control system for the liquid feeding device of the gum atomization test platform is proposed. The control system includes an operation adjustment module and a control module. The control module establishes communication with the controller of the sugar liquid storage unit 1 and the pipeline feeding system through the industrial bus, receives and processes real-time monitoring data from the density sensor 2, viscometer 3, flow controller 10 and other metering devices, and sends adjustment commands to the actuator to adjust the speed of the gear pump 4 and the spray flow of the nozzle 13. The operation adjustment module has built-in operating modes and can receive operation commands from the touch screen computer to select the corresponding operating mode. The control module and operation adjustment module are configured in the touchscreen computer. The touchscreen computer has a built-in high-speed camera data interface and is connected to a high-speed camera that captures the spraying status of nozzle 13, displaying the droplet size distribution. The human-machine interface of the touchscreen computer is equipped with a touch screen and supports process formula management, real-time trend curve analysis, and electronic batch record generation.

[0039] The control system adopts a distributed architecture design. The control module uses a PLC as the core control logic and integrates a multi-protocol communication module, a data acquisition unit, and an execution control unit to achieve fully automated management of the gum syrup supply process. The control system monitors the physical properties of the syrup in real time through various high-precision sensors and viscometers, and transmits the data to the PLC for processing in real time. The control system is integrated in a dustproof electrical control cabinet and connects various high-precision sensors and actuators through shielded cables. Each high-precision sensor collects temperature, humidity, pressure, density, and viscosity data in real time, which are then processed by filtering algorithms and fed back to the control module.

[0040] The actuators include a gear pump 4 driven by a servo motor, a pneumatic shut-off valve 6 and a pneumatic three-way valve 7 controlled by a solenoid valve, and an ultrasonic oscillating plate 119 driven by piezoelectric ceramics. Based on the control instructions of the control module, the flow rate, pressure and stirring intensity are precisely adjusted to ensure the stability of the liquid delivery and the uniformity of atomization.

[0041] The control module uses fuzzy logic and adaptive PID algorithms to dynamically adjust control parameters based on the density and viscosity of the feed liquid, optimizing temperature compensation and pressure stability in steam ejection or pneumatic ejection modes. For example, it optimizes the speed of gear pump 4 based on viscosity changes or adjusts steam pressure according to droplet distribution. The touchscreen computer interface is embedded in the electrical control cabinet door panel, supporting parameter setting, real-time monitoring, and data export functions. Process recipes can be stored and recalled with a single click. The system has a built-in redundancy fault-tolerant mechanism; in an emergency, it automatically cuts off the electric heating element 110 and the gas supply, and activates the pressure relief valve to ensure operational safety.

[0042] The operation adjustment module has built-in operating modes covering preheating preparation mode, sugar steam ejection mode, flavor air compression ejection mode, and tank pipeline deep cleaning mode.

[0043] The preheating preparation status modes include: Based on the viscosity feedback measured by the viscometer 3, the stirring mode is selected. In the high viscosity mode, the stirring arm 118 spray hole cyclone is activated. In the standard mode, the ultrasonic oscillating plate 119 is started. Ultrasonic pretreatment eliminates air bubbles in the liquid. The electric heating element 110 heats the heat-conducting medium to circulate and raise the temperature to the preset temperature. The sensor performs self-test calibration.

[0044] Sugar vapor ejection modes include: The pneumatic three-way valve 7 is activated to switch to the steam path. The gear pump 4 dynamically adjusts the flow rate. The high-speed camera provides real-time feedback on the droplet uniformity of the nozzle 13 and triggers parameter adjustments. Steam pressure: If the droplets are too large or unevenly distributed, and the CV value exceeds the standard, the steam pressure is increased to enhance the shear force and refine the droplets. Gear pump 4 speed: Adjusts the liquid flow rate (e.g., reducing the speed to decrease the liquid supply) to avoid overload and droplet adhesion. Pneumatic three-way valve 7 opening: Controls the mixing ratio of steam and liquid to optimize atomization efficiency. The multi-stage atomization chamber of the nozzle 13 refines the droplets step by step. Residual liquid is recovered to the liquid tank 101 and discharged from the liquid tank 101 through the drain pipe 109.

[0045] Fragrance pressurized ejection modes include: The pneumatic three-way valve 7 closes the steam passage, and the pneumatic shut-off valve 6 switches to the air pressure passage. The flow controller 10 (a mass flow controller, a relatively mature device in industrial automation; its core function is to regulate fluid flow through solenoid valves or proportional valves, and integrates sensors to provide real-time data feedback to the PLC for closed-loop control. In the fragrance air pressure ejection mode, the flow controller is specifically used to precisely adjust the mixing ratio of compressed air and liquid to ensure atomization stability) adjusts the gas-liquid mixing ratio and optimizes droplet morphology. By real-time monitoring and automatic adjustment of compressed air pressure, liquid flow, and mixing ratio, combined with a multi-stage atomization structure, the droplets achieve a uniform, fine, and concentrated atomization state; a pre-cleaning process is triggered after spraying.

[0046] The deep cleaning modes for tank pipelines include: When the drain valve 107 is opened, the gear pump 4 reverses direction, emptying the liquid tank 101 and the residual liquid in the pipeline. The level gauge 106 monitors the emptying status. After the residual liquid is emptied, cleaning agent is injected, and the pipeline is flushed with high-pressure water circulation. Ultrasonic vibration is used to peel off the deposits on the tank wall, and compressed air is delivered through the nozzle of the lower stirring arm 118 for purging and drying. In all the above modes, during the preheating stage, the liquid is heated by circulating heat transfer oil, ultrasonic vibration eliminates bubbles, and the stirring arm, in conjunction with the compressed air nozzle, enhances fluidity. In the steam ejection mode, the pneumatic three-way valve 7 switches to the steam source, and the liquid and steam are finely sprayed through a multi-stage atomization chamber. A high-speed camera provides real-time feedback on droplet uniformity and triggers dynamic adjustment. In the compressed air ejection mode, compressed air is premixed with the liquid, the flow controller 10 precisely adjusts the gas-liquid ratio, and atomization is completed after the nozzle 13 is locked at the angle. During deep cleaning, the system drains the residual liquid, injects neutral detergent for circulating rinsing, the ultrasonic vibration plate 119 removes deposits from the tank wall, and compressed air purging combined with heating drying ensures pipeline cleanliness. Data from each mode is automatically recorded and reports are generated, significantly improving experimental efficiency and repeatability.

[0047] In one embodiment, reference Figure 6 A control method for the liquid feeding device of the gum atomization test platform is proposed, which includes the following steps: Step a, Start the preheating preparation mode: Control system initialization and stirring mode selection, temperature control and liquid preheating, sensor calibration and system self-test, ultrasonic pretreatment and stability optimization, including the following: Step a1: Initialize and select the stirring mode: After starting the system, the touchscreen computer displays the preheating preparation interface. Users can set parameters such as stirring time and preset temperature range, and select the stirring mode based on the viscosity value of the gum syrup monitored by viscometer 3. In the high-viscosity stirring mode, the multi-stage U-shaped blades of the lower stirring arm 118 are activated, and compressed air is sprayed out through the nozzle to form an air vortex to prevent the liquid from settling. In standard mixing mode, the straight blades of the upper mixing arm 117 are activated to uniformly mix the surface of the liquid, and the ultrasonic oscillating plate 119 is activated to eliminate air bubbles in the liquid.

[0048] Step a2, temperature control and liquid preheating; When the electric heating element 110 is activated, it combines with the heat transfer oil circulation system of the double-layer tank to heat the heat transfer medium and gradually raise the temperature of the liquid to the preset temperature range. The oil temperature sensor 104 provides real-time data feedback to ensure uniform temperature distribution inside the tank, while the temperature and humidity sensor 113 detects changes in the temperature of the liquid inside the tank. The level gauge 106 monitors the liquid volume and triggers an alarm to prompt for liquid replenishment when the liquid level is low.

[0049] Step a3, sensor calibration and system self-test; The system automatically verifies the data stability of density sensor 2, viscometer 3 and pressure sensor 12. If the deviation exceeds the limit, it prompts manual intervention or starts the automatic calibration program.

[0050] Step a4, Ultrasonic pretreatment and stability optimization: The ultrasonic oscillating plate 119 vibrates at high frequency to eliminate tiny air bubbles in the liquid, while the lower stirring arm 118 sprays low-pressure air intermittently to enhance the fluidity of the liquid. After reaching the preset time, temperature and other parameters, the liquid enters the preheating preparation state.

[0051] Step b, Activate the sugar steam injection mode: mode selection and parameter setting, steam path initialization, dynamic flow adjustment and atomization preparation, high-speed camera feedback optimization, multi-stage atomization and directional injection, residual liquid recovery and system reset, including the following steps: Step b1, Mode Selection and Parameter Setting: Select "Sugar Steam Injection Mode" on the touchscreen of the computer, set the target steam pressure, flow rate and injection angle; calculate the initial steam and liquid mixing ratio based on the real-time liquid density and viscosity data measured by density sensor 2 and viscometer 3.

[0052] Step b2, Steam passage initialization: Start the pneumatic three-way valve 7 to switch to the steam passage, start the steam generator and preheat the pipeline to the process temperature, and pressure sensor 12 monitors the steam pressure in real time.

[0053] Step b3, Dynamic Flow Adjustment and Atomization Preparation: Based on the viscosity feedback measured by viscometer 3, the control module adjusts the speed of gear pump 4 and the power of steam generator to match the set pressure; Step b4, High-speed camera feedback optimization: A high-speed camera captures the atomized droplet size distribution in real time. If the uniformity CV value of the atomized droplet size exceeds the threshold, the control module is triggered to adjust the steam pressure or flow rate and optimize the set parameters.

[0054] Step b5, multi-stage atomization and directional spraying: Steam and liquid are gradually refined through multi-stage atomization chambers within the nozzle 13, and the angle adjuster 14 adjusts the spray coverage of the nozzle 13 according to experimental requirements.

[0055] Step b6, Residual liquid recovery and system reset: After the spraying is completed, the steam valve of the steam generator is closed, the gear pump 4 runs in reverse, and the residual liquid is recovered to the liquid tank 101 through the return port 114. The experimental parameters are recorded in the electronic batch record management system.

[0056] Step c, Activate the fragrance compressed air ejection mode: mode selection and compressed air path activation, adaptive control of mixing parameters, real-time monitoring and adjustment by high-speed camera, gas-liquid coordinated atomization and injection execution, pipeline pre-cleaning and data archiving, including the following processes: Step c1, Mode selection and air compressor circuit startup: Select "Fragrance Air Compressed Ejection Mode" on the touchscreen computer, set the target air pressure, flow rate and injection angle, etc., and the pneumatic shut-off valve 6 switches to the air pressure passage. Compressed air enters the pipeline supply system after calibration.

[0057] Step c2, Hybrid parameter adaptive control: The lower stirring arm 118 stirs the fragrance at an appropriate speed. Compressed air and liquid are premixed in the pipeline before the nozzle 13 (first-stage mechanical impact chamber 131). The gas-liquid ratio is adjusted in real time by the flow controller 10.

[0058] Step c3, real-time monitoring and adjustment of high-speed camera: A high-speed camera monitors the shape of the atomized droplets. If adhesion or uneven distribution occurs, the control module fine-tunes the air pressure flow or the speed of the gear pump 4 to optimize the set parameters and achieve atomization uniformity.

[0059] Step c4, gas-liquid synergistic atomization and jetting execution: The mixed fluid is initially dispersed by the nozzle 13 through the first-stage mechanical impact chamber 131, the second-stage vortex shear chamber 132 enhances the shearing force through vortex, and the third-stage array of multi-hole nozzles 133 outputs uniform droplets.

[0060] Step c5, Pipeline pre-cleaning and data archiving: After spraying is completed, the compressed air delivery valve closes, triggering the pre-cleaning process. Gear pump 4 runs in reverse to empty the pipeline of residual fragrance, and the experimental parameters are automatically stored to generate a report.

[0061] Step d: Initiate the deep cleaning mode for the tank and pipelines: residual liquid drainage and pretreatment, high-pressure water circulation and ultrasonic synergy, air-liquid purging and drying, system reset and cleaning report generation, including the following steps: Step d1, residual liquid drainage and pretreatment: Set the cleaning time and parameters, open the valve of drain port 107, and the gear pump 4 runs in reverse to empty the liquid tank 101 and the pipeline of residual liquid. The level gauge 106 monitors the emptying status. After completion, inject neutral cleaning agent into the liquid tank 101 and the pipeline feeding system.

[0062] Step d2, High-pressure water circulation combined with ultrasound: The cleaning agent mixture is flushed through the pipeline using a high-pressure water pump connected to the pipeline supply system, especially at key nodes of the pipeline supply system (such as nozzle 13, pneumatic shut-off valve 6, pneumatic three-way valve 7, ball valve 8, and liquid check valve 9). The ultrasonic vibration plate 119 vibrates at high frequency to remove deposits from the inner wall of the liquid tank 101.

[0063] Step d3, gas-liquid purging and drying: Compressed air is used to purge residual moisture from the pipeline, and an electric heating element 110 heats up to assist in drying the liquid tank 101. A temperature and humidity sensor 113 measures the humidity value inside the liquid tank 101 until the humidity reaches the standard.

[0064] Step d4, System Reset and Cleaning Report Generation: Once the preset cleaning time and parameters are reached, all unit mechanisms are shut down, all valves are reset to standby mode, and the touch screen computer generates a cleaning report, recording the time and key parameters, and archives it to the database.
