Abstract
Description
Technical Field
[0001] This invention relates to the field of cigarette processing technology, and in particular to a multi-environment tobacco conveying simulation device for testing the moisture content of tobacco shreds. Background Technology
[0002] The moisture content of tobacco shreds is a crucial control parameter in the cigarette manufacturing process, affecting not only the overall quality and combustion performance of the tobacco but also directly impacting the consumer's smoking experience. To ensure the stability of tobacco shred quality, tobacco companies need to strictly monitor and control the moisture content of tobacco shreds at every stage of production.
[0003] The conveying process in cigarette manufacturing involves a decrease in tobacco temperature and a change in moisture content. This change in moisture content is influenced by various factors, including tobacco stacking, conveying time, and ambient temperature and humidity. Due to significant differences in the design of conveying devices at different cigarette factories, the temperature and humidity conditions and conveying length experienced by the tobacco during transport vary, making it difficult to accurately predict the moisture content changes. Multiple tests are often required to determine the final moisture content. Traditional tobacco processing involves large-scale, high-volume transport with long distances and large quantities of tobacco conveyed at a time, resulting in substantial resource waste during moisture content testing. This significantly increases the cost of cigarette manufacturing and reduces its efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a multi-environment tobacco conveying simulation device for testing the moisture content of tobacco shreds. This device can simulate the tobacco conveying process under different working conditions, thereby reducing the cost of tobacco moisture content testing and improving the efficiency of cigarette processing.
[0005] This invention proposes a multi-environment tobacco conveying simulation device for testing the moisture content of tobacco shreds, comprising a temperature and humidity control mechanism, a wind control mechanism disposed within the temperature and humidity control mechanism, a loading mechanism for loading tobacco shreds, an air inlet duct connecting the loading mechanism and the wind control mechanism, and an air outlet duct connecting the loading mechanism and the temperature and humidity control mechanism; the temperature and humidity control mechanism is used to adjust the temperature and humidity of its internal environment to a set value, the wind control mechanism delivers air from inside the temperature and humidity control mechanism to the loading mechanism through the air inlet duct and controls the airflow speed to drive the tobacco shreds to move in the loading mechanism, and the air outlet duct returns the air flowing through the loading mechanism to the temperature and humidity control mechanism.
[0006] Furthermore, the loading mechanism includes a drying chamber for loading tobacco shreds, and a transparent door for opening or closing the drying chamber. When the transparent door opens the drying chamber, tobacco shreds can be loaded into the drying chamber. When the transparent door closes the drying chamber, the interior of the drying chamber can be observed through the transparent door.
[0007] Furthermore, one end of the transparent door is hinged to the wire drying chamber, and the loading mechanism also includes a sealing latch at the other end of the transparent door and a sealing lock seat on the wire drying chamber. The sealing latch can be engaged or disengaged from the sealing lock seat.
[0008] Furthermore, the drying chamber has an air inlet and an air outlet on opposite sides, one end of the air inlet pipe is connected to the air inlet and the other end is connected to the air control mechanism, one end of the air outlet pipe is connected to the air outlet and the other end is connected to the temperature and humidity control mechanism, and the loading mechanism also includes an air outlet filter screen disposed at the air outlet and a filter screen pressing sheet for fixing the air outlet filter screen in the drying chamber.
[0009] Furthermore, the feeding mechanism also includes a first anemometer and a sealing plug. The first anemometer is installed on the drying chamber and is used to calibrate the wind speed in the drying chamber. The sealing plug is used to seal the drying chamber after the first anemometer has been removed after calibration.
[0010] Furthermore, the feeding mechanism also includes a feeding tray disposed in the tobacco drying chamber and an adjusting pad disposed at the bottom of the feeding tray. The feeding tray is used to hold tobacco, and the adjusting pad is used to adjust the height of the feeding tray.
[0011] Furthermore, the air control mechanism includes a speed-regulating fan connected to the temperature and humidity control mechanism, an air supply duct with one end connected to the speed-regulating fan and the other end connected to the air inlet duct, and a wind speed adjustment component disposed on the air supply duct. The speed-regulating fan is used to draw air from inside the temperature and humidity control mechanism to the air supply duct, the air supply duct is used to supply air to the air inlet duct, and the wind speed adjustment component is used to control the wind speed supplied by the air supply duct.
[0012] Furthermore, the wind speed regulating component includes a second anemometer installed on the air supply duct and an electric air valve installed on the air supply duct. The second anemometer is used to monitor the wind speed supplied by the air supply duct, and the electric air valve is used to regulate the wind speed supplied by the air supply duct.
[0013] Furthermore, the temperature and humidity control mechanism includes a balancing chamber and a constant temperature and humidity unit. The constant temperature and humidity unit is connected to the balancing chamber and is used to control the temperature and humidity of the balancing chamber. The balancing chamber is used to adjust and maintain the temperature and humidity of its internal environment in a balanced state. The air control mechanism is located in the balancing chamber, and the air outlet duct connects the loading mechanism to the balancing chamber.
[0014] Furthermore, the temperature and humidity control mechanism also includes a temperature and humidity sensor disposed in the balance chamber, which is used to detect the temperature and humidity of the balance chamber.
[0015] The multi-environment tobacco conveying simulation device for testing the moisture content of tobacco shreds proposed in this invention has the following beneficial effects:
[0016] (1) The device regulates the temperature and humidity of its internal environment through the temperature and humidity control mechanism. The air control mechanism delivers the air that has been regulated by the temperature and humidity control mechanism to the loading mechanism through the air inlet pipe, driving the tobacco to move in the loading mechanism. At the same time, the air is returned to the temperature and humidity control mechanism through the air outlet pipe, thereby simulating the tobacco conveying process under different working conditions.
[0017] (2) In the process of simulating the tobacco conveying process under different working conditions, this device detects the moisture content of the tobacco before and after conveying, thereby mastering the data on the change of tobacco moisture content in the tobacco conveying process, providing scientific guidance for setting the moisture parameters of the tobacco conveying process, thereby reducing the cost of tobacco moisture content testing and improving the efficiency of cigarette processing.
[0018] (3) The air supplied to the loading mechanism through the air inlet pipe is returned to the temperature and humidity control mechanism through the air outlet pipe after passing through the loading mechanism, thereby realizing the recycling of air, making the structure of the device simple and convenient, easy to implement, and reducing the cost of using the device.
[0019] (4) The temperature and humidity control mechanism of this device includes a balance chamber and a constant temperature and humidity unit. Specifically, the balance chamber and the constant temperature and humidity unit are fixedly installed on the frame. The constant temperature and humidity unit is located below the balance chamber and connected to the balance chamber. The temperature and humidity of the balance chamber are controlled by the constant temperature and humidity unit. The balance chamber adjusts and maintains the temperature and humidity of its internal environment in a balanced state, so that the temperature and humidity of the internal environment of the balance chamber reach and are maintained at the set value.
[0020] (5) The temperature and humidity control mechanism of this device also includes a temperature and humidity sensor. The temperature and humidity sensor is installed in the balance chamber. The temperature and humidity of the environment inside the balance chamber are detected by the temperature and humidity sensor, and the detected signal is transmitted to the control system. The control system controls the constant temperature and humidity unit to regulate the temperature and humidity of the environment inside the balance chamber, thereby achieving precise regulation of the temperature and humidity of the environment inside the balance chamber.
[0021] (6) The feeding mechanism of this device includes a drying chamber and a transparent door. The drying chamber is used to load tobacco. When the transparent door opens the drying chamber, it is convenient for the tobacco to be fed into the feeding mechanism. When the transparent door closes the drying chamber, the movement of the tobacco inside the drying chamber can be observed through the transparent door so as to make timely adjustments, thereby making the use of this device simpler, more convenient and easier to implement.
[0022] (7) The feeding mechanism of this device also includes an air outlet filter and a filter press plate. The air outlet filter is set at the air outlet of the drying chamber and is fixedly installed in the drying chamber by the filter press plate. When the air flowing through the drying chamber is returned to the balance chamber through the air outlet pipe, the air outlet filter blocks the tobacco in the drying chamber, thereby realizing the recycling of air, reducing the operating cost of this device, and preventing the tobacco from entering the balance chamber and affecting the working performance of the balance chamber;
[0023] (8) The feeding mechanism of this device also includes a first anemometer and a sealing plug. The first anemometer is used to calibrate the wind speed in the drying chamber to ensure that the wind speed in the drying chamber reaches the set value during the simulation. After calibration, the first anemometer is removed from the drying chamber and the mounting hole on the drying chamber for installing the first anemometer is sealed by the sealing plug to ensure the sealing of the drying chamber and prevent the external environment from affecting the simulation of the tobacco conveying process.
[0024] (9) The feeding mechanism of this device also includes a feeding tray and an adjusting pad. The feeding tray is set in the drying chamber, and the adjusting pad is set at the bottom of the feeding tray to support the feeding tray. The height of the feeding tray is adjusted by adjusting the pad so that the tobacco in the feeding tray is closer to the position calibrated by the first anemometer. This makes the simulation of the conveying process of tobacco in different wind speed environments more realistic and reliable, and makes the data on the change of tobacco moisture content in the tobacco conveying process more realistic and reliable.
[0025] (10) The wind speed regulation component of this device includes a second anemometer and an electric air valve, both of which are installed on the air supply duct. When the air supply duct supplies air to the air inlet duct, the anemometer monitors the wind speed supplied by the air supply duct and transmits the monitored signal to the control system. The control system controls the electric air valve to regulate the wind speed supplied by the air supply duct, thereby achieving precise regulation of the wind speed supplied by the air supply duct.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1, please refer to Figures 1-5 :
[0035] An embodiment of the present invention provides a multi-environment tobacco conveying simulation device for testing the moisture content of tobacco shreds, including a temperature and humidity control mechanism, a wind control mechanism 3 disposed in the temperature and humidity control mechanism, a loading mechanism 4 for loading tobacco shreds, an air inlet pipe 5 connecting the loading mechanism 4 and the wind control mechanism 3, and an air outlet pipe 6 connecting the loading mechanism 4 and the temperature and humidity control mechanism.
[0036] The temperature and humidity control mechanism is used to adjust the temperature and humidity of its internal environment to the set value. The air control mechanism 3 delivers the air inside the temperature and humidity control mechanism to the loading mechanism 4 through the air inlet pipe 5 and controls the air speed to drive the tobacco shreds to move in the loading mechanism 4. The air outlet pipe 6 returns the air flowing through the loading mechanism 4 to the temperature and humidity control mechanism.
[0037] In this application, the multi-environment tobacco conveying simulation device includes a temperature and humidity control mechanism, a wind control mechanism 3, a loading mechanism 4, an air inlet duct 5, and an air outlet duct 6. The loading mechanism 4 is used to load tobacco, and the temperature and humidity control mechanism is used to adjust the temperature and humidity of its internal environment to set values. The wind control mechanism 3 is located within the temperature and humidity control mechanism, and the air inlet duct 5 connects the loading mechanism 4 to the wind control mechanism 3.
[0038] The air controlled by the air control mechanism 3 is supplied with air whose temperature and humidity are adjusted to the set value inside the temperature and humidity control mechanism. The air is then supplied to the air inlet pipe 5 and then to the loading mechanism 4. This drives the tobacco loaded in the loading mechanism 4 to move within the loading mechanism 4, thereby simulating the tobacco conveying process in an environment with the set temperature and humidity. Furthermore, by adjusting the set value during multiple simulations, the tobacco conveying process in different temperature and humidity environments can be simulated.
[0039] In this application, when the air whose temperature and humidity inside the temperature and humidity control mechanism is adjusted to the set value is delivered to the air inlet duct 5 by the air control mechanism 3, the air control mechanism 3 can also control the air speed of the air supply, thereby controlling the air speed of the air supply duct 5 towards the loading mechanism 4, and thus realizing the simulation of the tobacco conveying process under different wind speed environments.
[0040] The air supplied to the loading mechanism 4 through the air inlet duct 5 is then returned to the temperature and humidity control mechanism through the air outlet duct 6 after passing through the loading mechanism 4, thereby realizing the recycling of air. This makes the structure of the device simple, convenient, and easy to implement, and reduces the operating cost of the device.
[0041] Therefore, in this application, the temperature and humidity of the internal environment are regulated by the temperature and humidity control mechanism, and the air control mechanism 3 delivers the air that has been regulated by the temperature and humidity control mechanism to the loading mechanism 4 through the air inlet pipe 5, driving the tobacco to move in the loading mechanism 4. At the same time, the air is returned to the temperature and humidity control mechanism through the air outlet pipe 6, thereby simulating the tobacco conveying process under different working conditions.
[0042] In simulating the tobacco conveying process under different working conditions, the moisture content of the tobacco before and after conveying is detected, thereby grasping the data on the change of tobacco moisture content during the tobacco processing and conveying process. This provides scientific guidance for setting moisture parameters in the tobacco processing process, thereby reducing the cost of tobacco moisture content testing and improving the efficiency of cigarette processing.
[0043] Specifically, in this embodiment, the temperature and humidity control mechanism includes a balance chamber 1 and a constant temperature and humidity unit 2. The constant temperature and humidity unit 2 is connected to the balance chamber 1 and is used to control the temperature and humidity of the balance chamber 1. The balance chamber 1 is used to adjust and maintain the temperature and humidity of its internal environment in a balanced state. The air control mechanism 3 is located in the balance chamber 1, and the air outlet duct 6 connects the loading mechanism 4 to the balance chamber 1.
[0044] In this application, the temperature and humidity control mechanism includes a balance chamber 1 and a constant temperature and humidity unit 2. Specifically, the balance chamber 1 and the constant temperature and humidity unit 2 are fixedly installed on the frame. The constant temperature and humidity unit 2 is located below the balance chamber 1 and connected to the balance chamber 1, thereby controlling the temperature and humidity of the balance chamber 1 through the constant temperature and humidity unit 2. The balance chamber 1 adjusts and maintains the temperature and humidity of its internal environment in a balanced state, so that the temperature and humidity of the internal environment of the balance chamber 1 reach and maintain the set value.
[0045] The air control mechanism 3 is set in the balance chamber 1. The loading mechanism 4 is fixedly connected to the balance chamber 1 through the air inlet pipe 5 and the air outlet pipe 6. It is fixedly installed on the balance chamber 1, and the air inlet pipe 5 is connected to the air control mechanism 3 in the balance chamber 1. So when the air control mechanism 3 is activated, the air in the balance chamber 1 with the temperature and humidity reaching the set value is transported to the loading mechanism 4 through the air inlet pipe 5.
[0046] The loading mechanism 4 contains tobacco shreds, which are supplied with air through the air inlet duct 5. The air speed is adjusted by the air control mechanism 3 to drive the tobacco shreds to move within the loading mechanism 4. This simulates the conveying process of tobacco shreds under different temperature, humidity, and wind speed conditions. During the simulation, the moisture content of the tobacco shreds before and after conveying is detected, thereby obtaining data on the change in moisture content of the tobacco shreds during the tobacco processing and conveying process. This provides scientific guidance for setting moisture parameters in the tobacco processing process, thereby reducing the cost of tobacco moisture content testing and improving the efficiency of cigarette processing.
[0047] The air outlet duct 6 connects the loading mechanism 4 to the balance chamber 1. The air delivered to the loading mechanism 4 through the air inlet duct 5 flows through the loading mechanism 4 and is then returned to the balance chamber 1 through the air outlet duct 6, thereby realizing the recycling of air. This makes the structure of the device simple, convenient, and easy to implement, and reduces the operating cost of the device.
[0048] In this application, the specific structure and working principle of the balance chamber 1 and the constant temperature and humidity unit 2 are common knowledge that should be known to those skilled in the art, and therefore will not be described in detail here.
[0049] Furthermore, in this embodiment, the temperature and humidity control mechanism also includes a temperature and humidity sensor 11, which is installed in the balance chamber 1. The temperature and humidity sensor 11 detects the temperature and humidity of the internal environment of the balance chamber 1 and transmits the detected signal to the control system. The control system controls the constant temperature and humidity unit 2 to regulate the temperature and humidity of the internal environment of the balance chamber 1, thereby achieving precise regulation of the temperature and humidity of the internal environment of the balance chamber 1.
[0050] After being regulated by the constant temperature and humidity unit 2 and adjusted by the balance chamber 1 itself, the temperature and humidity of the internal environment of the balance chamber 1 reach and are maintained at the set value. Then, the air in the balance chamber 1 with the set temperature and humidity is transported to the air inlet duct 5 through the air control mechanism 3. The air inlet duct 5 blows air towards the loading mechanism 4, driving the tobacco to move in the loading mechanism 4, thereby simulating the transportation process of tobacco under different temperature, humidity and wind speed environments.
[0051] Specifically, in this embodiment, the loading mechanism 4 includes a drying chamber 41 and a transparent door 42. The drying chamber 41 is used to load tobacco shreds, and the transparent door 42 is used to open or close the drying chamber 41. When the transparent door 42 opens the drying chamber 41, tobacco shreds can be loaded into the drying chamber 41, thereby facilitating the feeding of tobacco shreds into the loading mechanism 4.
[0052] After the material is fed, the drying chamber 41 can be sealed through the transparent door 42, thus creating a sealed environment inside the drying chamber 41. The air control mechanism 3 delivers the air inside the balance chamber 1 to the air inlet duct 5, which blows air into the drying chamber 41, thereby driving the tobacco to move in the drying chamber 41, simulating the process of tobacco conveying.
[0053] During this process, the movement of tobacco shreds inside the drying chamber 41 can be observed through the transparent door 42, allowing for timely adjustments and making the device simpler, more convenient, and easier to implement. In this application, the transparent door 42 can be made of transparent glass.
[0054] Specifically, in this embodiment, one end of the transparent door 42 is hinged to the wire drying chamber 41, and the loading mechanism 4 also includes a sealing buckle 421 and a sealing lock seat. The sealing buckle 421 is disposed at the other end of the transparent door 42, and the sealing lock seat is disposed on the wire drying chamber 41. The sealing buckle 421 can be engaged or disengaged from the sealing lock seat.
[0055] When the sealing latch 421 disengages from the sealing seat, the other end of the transparent door 42 is released from the drying chamber 41, allowing the transparent door 42 to rotate around the end that is hinged to the drying chamber 41, thereby opening the drying chamber 41 through the transparent door 42 so that tobacco can be quickly loaded into the drying chamber 41.
[0056] After the tobacco is loaded, the transparent door 42 is rotated in the opposite direction around the end that is hinged to the drying chamber 41 until the transparent door 42 closes the drying chamber 41. Then, the other end of the transparent door 42 is fixed to the drying chamber 41 by the sealing lock 421 and the sealing lock seat, thereby achieving the sealing of the drying chamber 41.
[0057] Specifically, in this application, a sealing silicone strip can be provided on the outer periphery of the transparent door 42, thereby further improving the sealing performance of the drying chamber 41 when the transparent door 42 closes the drying chamber 41.
[0058] Specifically, in this embodiment, air inlets 411 and air outlets 412 are respectively provided on opposite sides of the drying chamber 41. One end of the air inlet pipe 5 is connected to the air inlet 411, and the other end is connected to the air control mechanism 3. Thus, when the air control mechanism 3 delivers the air inside the balance chamber 1 to the air inlet pipe 5, air can be blown into the drying chamber 41 through the air inlet pipe 5, thereby driving the tobacco to move in the drying chamber 41, simulating the process of tobacco conveying.
[0059] One end of the air outlet duct 6 is connected to the air outlet 412, and the other end is connected to the balance chamber 1. This allows the air that is delivered to the drying chamber 41 through the air inlet duct 5 to be returned to the balance chamber 1 through the air outlet duct 6 after passing through the drying chamber 41, thus realizing the recycling of air. This makes the structure of the device simple, convenient, and easy to implement, and reduces the cost of using the device.
[0060] In this application, the feeding mechanism 4 also includes an air outlet filter 43 and a filter plate 44. The air outlet filter 43 is disposed at the air outlet 412 of the drying chamber 41 and is fixedly installed in the drying chamber 41 by the filter plate 44.
[0061] When the air flowing through the drying chamber 41 is returned to the balance chamber 1 through the air outlet duct 6, the air outlet filter 43 blocks the tobacco in the drying chamber 41, thereby realizing the recycling of air and reducing the operating cost of the device, and preventing the tobacco from entering the balance chamber 1 and affecting the working performance of the balance chamber 1.
[0062] Specifically, in this embodiment, the feeding mechanism 4 further includes a first anemometer 45 and a sealing plug 46. The first anemometer 45 is installed on the drying chamber 41 and is used to calibrate the wind speed of the drying chamber 41. The sealing plug 46 is used to seal the drying chamber 41 after the calibration is completed and the first anemometer 45 is removed.
[0063] In this application, before simulating the tobacco conveying process using this device, the wind speed in the drying chamber 41 is calibrated by the first anemometer 45 to ensure that the wind speed in the drying chamber 41 reaches the set value in the subsequent simulation process. This makes the simulation of the tobacco conveying process under different wind speed environments more realistic and reliable, and thus makes the data on the change of tobacco moisture content in the tobacco conveying process more realistic and reliable.
[0064] Since the first anemometer 45 needs to partially extend into the drying chamber 41 to detect the wind speed, the calibration of the first anemometer 45 is performed so that the wind speed in the drying chamber 41 reaches the set value. In order to avoid collisions between the moving tobacco in the drying chamber 41 and the first anemometer 45 during the formal simulation process, which would affect the measurement accuracy of the first anemometer 45 or cause damage to the first anemometer 45, this is necessary.
[0065] Therefore, before the formal simulation of the tobacco conveying process is carried out, the first anemometer 45 needs to be removed from the drying chamber 41. At this time, the mounting hole on the drying chamber 41 used to install the first anemometer 45 is sealed by the sealing plug 46 to ensure the sealing of the drying chamber 41 and prevent the external environment from affecting the simulation of the tobacco conveying process.
[0066] Specifically, in this embodiment, the feeding mechanism 4 further includes a feeding tray 47 disposed in the drying chamber 41, and an adjusting pad 48 disposed at the bottom of the feeding tray 47. The feeding tray 47 is used to hold tobacco, and the adjusting pad 48 is used to adjust the height of the feeding tray 47.
[0067] In this application, the loading mechanism 4 also includes a loading tray 47 and an adjusting pad 48. The loading tray 47 is disposed in the drying chamber 41, and the adjusting pad 48 is disposed at the bottom of the loading tray 47 to support the loading tray 47. When the transparent door 42 opens the drying chamber 41, tobacco can be loaded onto the loading tray 47, thereby holding the tobacco through the loading tray 47 and realizing the loading of tobacco into the drying chamber 41.
[0068] Since the air inlet 411 and air outlet 412 are set at fixed heights on both sides of the drying chamber 41, and the internal space of the drying chamber 41 is relatively large, the air velocity inside the drying chamber 41 is not uniformly distributed during the process of air supply through the air inlet 411 and air discharge through the air outlet 412.
[0069] Therefore, after the first anemometer 45 calibrates the wind speed in the drying chamber 41, the height of the loading tray 47 is adjusted by adjusting the pad 48, so that the tobacco shreds in the loading tray 47 are closer to the position calibrated by the first anemometer 45. This makes the simulation of the conveying process of tobacco shreds in different wind speed environments more realistic and reliable, and thus makes the data on the change of tobacco moisture content in the tobacco shreds during the tobacco processing conveying process more realistic and reliable.
[0070] Specifically, in this embodiment, the wind control mechanism 3 includes a speed-regulating fan 31, an air supply duct 32, and a wind speed adjustment component. The speed-regulating fan 31 is fixedly installed on the balance chamber 1, and the air inlet of the speed-regulating fan 31 is connected to the balance chamber 1. The air supply duct 32 is located in the balance chamber 1, and one end is connected to the air outlet of the speed-regulating fan 31, and the other end is connected to the air inlet duct 5.
[0071] By starting the speed-regulating fan 31, the air inside the balance chamber 1, which has reached the set temperature and humidity, is delivered to the air supply duct 32, and then delivered to the air inlet duct 5 through the air supply duct 32, so that the air inlet duct 5 blows air toward the drying chamber 41.
[0072] The wind speed adjustment component is installed on the air supply duct 32. When the air supply duct 32 supplies air to the air inlet duct 5 and the air inlet duct 5 blows air towards the drying chamber 41, driving the tobacco to move in the drying chamber 41, the wind speed adjustment component adjusts the wind speed supplied by the air supply duct 32, thereby simulating the tobacco conveying process under different wind speed environments.
[0073] Specifically, in this embodiment, the wind speed regulation component includes a second anemometer 33 and an electric air valve 34, both of which are installed on the air supply duct 32. When the air supply duct 32 supplies air to the air inlet duct 5, the anemometer monitors the wind speed supplied by the air supply duct 32 and transmits the monitored signal to the control system. The control system then controls the electric air valve 34 to regulate the wind speed supplied by the air supply duct 32, thereby achieving precise regulation of the wind speed supplied by the air supply duct 32.
[0074] By regulating the wind speed of the air supply duct 32, the wind speed is maintained at the set value. Thus, the air supply duct 32 supplies air to the air inlet duct 5 at the set wind speed, and then the air inlet duct 5 blows air towards the drying chamber 41, driving the tobacco to move in the drying chamber 41, thereby simulating the tobacco conveying process under different wind speed conditions.
[0075] It is foreseeable that, in actual implementation, the wind speed regulating component in this embodiment is not limited to the electric air valve 34, but may also be other devices or equipment that can regulate the wind speed of the air supply duct 32.
[0076] Example 2:
