Description

Technical Field

[0001] The present application belongs to the technical field of tobacco processing, and in particular relates to a device for alcoholizing cut stems. Background Art

[0002] In the tobacco processing, tobacco aging is a crucial link. Aging refers to the process of removing green odors, improving aroma and other quality indicators through a specific treatment process after tobacco leaves are harvested and baked. The aging process not only affects the taste of tobacco, but is also directly related to the quality of the final tobacco product. At present, the aging of tobacco stems is usually carried out in an aging cabinet, which reduces the moisture content of the stems through the circulation of airflow, thereby achieving the purpose of aging.

[0003] However, the existing alcoholization technology has the following shortcomings: 1. Limited airflow regulation: The ventilation device of the existing alcoholization cabinet usually relies on a fixed airflow supply, and it is impossible to flexibly adjust the airflow delivery speed according to the moisture content or type of the shredded stems. Since shredded stems of different types or moisture contents have different requirements for airflow, the fixed airflow output is difficult to meet the actual needs, resulting in unsatisfactory alcoholization effect. 2. Uneven airflow coverage: The airflow delivery angle of the existing alcoholization cabinet is limited, and it is impossible to achieve full coverage of the shredded stems. Some shredded stems lose water quickly due to direct airflow, while the moisture content of shredded stems in other areas decreases slowly due to insufficient airflow coverage. This uneven alcoholization process easily leads to inconsistent quality of shredded stems, affecting the quality of the final product. 3. Poor equipment adaptability: The existing alcoholization equipment lacks the ability to dynamically adjust the size and angle of airflow output, and it is difficult to adapt to the processing requirements of shredded stems of different types and moisture contents. This limits the versatility and efficiency of the equipment and increases production costs. Summary of the invention

[0004] The present application provides a cut stem alcoholization device to solve the technical problems of poor adaptability to cut stems of different types and different moisture contents and uneven stem alcoholization caused by poor airflow and airflow coverage in traditional cut stem alcoholization devices.

[0007] The stem silk alcoholization equipment described in the present application also includes the following additional technical features:

[0008] The micro vortex generator includes a fixed rotating shaft and a vortex blade that can rotate around the fixed rotating shaft. The vortex blade has a vortex guide surface facing the air outlet. The vortex blade rotates around the fixed rotating shaft under the action of the airflow to form a spiral vortex airflow.

[0009] The guide groove spirally extends from a side close to the air outlet to a side away from the air outlet, and the number of the micro vortex generators is multiple and arranged at intervals in the guide groove.

[0010] The branch air duct is surrounded by a plate body, the guide plate is hinged to the plate body, the first driving member is installed on the warehouse body, the pulling member is a flexible pulling rope extending along the plate body, and the first driving member drives the flexible pulling rope to tighten to drive the guide plate to rotate in a direction in which the angle with the plate body is reduced.

[0011] The guide plate is provided with a connecting portion, the plate body is provided with a steering plate at the end close to the air outlet, the steering plate is provided with a through hole, the flexible pulling rope is passed through the through hole and connected to the connecting portion.

[0012] It also includes an elastic reset member disposed between the guide plate and the plate body, and the elastic reset member can drive the guide plate to rotate in a direction in which the angle between the guide plate and the plate body is enlarged.

[0013] A penetration pipe is provided on the inner wall of the plate body, and the interior of the penetration pipe is hollow to form a penetration cavity for the flexible pull rope to penetrate. Alternatively, a plurality of fixing buckles are provided at intervals on the inner wall of the plate body, and penetration grooves are formed between the fixing buckles and the plate body, and the flexible pull rope penetrates the penetration grooves in sequence.

[0014] The material dispensing mechanism includes a second driving member, a rotating shaft extending vertically inside the bin body, and a material dispensing plate arranged on the rotating shaft.

The second driving member drives the rotating shaft to rotate to drive the material dispensing plate to rotate and dispense materials in the alcoholization chamber.

[0015] The material-shifting plate includes a first plate body connected to the rotating shaft and a second plate body connected to the first plate body.

[0016] The alcoholization equipment also includes a tray for shredded stems and a third driving member acting on the tray. The tray is located at the bottom of the warehouse body and has a through hole in the middle for the rotating shaft to pass through. The third driving member can drive the tray to rotate in the opposite direction to the direction of rotation of the rotating shaft.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The shredded stem alcoholization device of the present application comprises a chamber having an alcoholization chamber, wherein a material shifting mechanism and an air supply unit are arranged in the alcoholization chamber, wherein the material shifting mechanism is used to shift the shredded stems so that the shredded stems can be dispersed, thereby reducing the probability of the shredded stems agglomerating into a mass, increasing the contact area between the shredded stems and the outside world, and increasing the alcoholization uniformity of the shredded stems; meanwhile, the air supply unit is used to provide airflow to the shredded stems in the alcoholization chamber, so that the shredded stems dispersed by the material shifting mechanism have their own moisture content uniformly reduced under the action of the airflow until the alcoholization standard is reached. During the operation of the air supply unit, the fan conveys airflow into the main air duct, and the airflow is discharged from the air outlet after passing through the main air duct and the branch air duct in sequence. Since a guide plate is provided at the air outlet, the guide plate can guide the airflow discharged from the air outlet, and the shredded stems are dispersed in various parts of the alcoholization chamber under the action of the material-dispensing mechanism. The guide plate can rotate relative to the branch air duct, thereby continuously guiding the airflow discharged from the air outlet to various parts of the alcoholization chamber, so that the shredded stems evenly distributed in the alcoholization chamber can be evenly affected by the airflow, thereby achieving uniform dehumidification of the shredded stems; that is, the present application achieves uniform distribution of the shredded stems in the alcoholization chamber through the cooperation of the material-dispensing mechanism and the air outlet unit, and evenly supplies air to the evenly distributed shredded stems, thereby improving the alcoholization effect of the shredded stems in many aspects. In addition, for some shredded stems with a high moisture content, in order to speed up the alcoholization efficiency, it is necessary to increase the airflow input in the early stage of the alcoholization process to achieve rapid dehumidification. When the fan power is constant, the first driving member can be used to drive the pulling member to move, and the guide plate can be driven to rotate, so that the guide plate rotates in the direction of reducing the size of the air outlet, reducing the air outlet area at the air outlet, so that the gas in the branch air duct must be pumped out at a faster speed under the limitation of a smaller movement space, so as to increase the airflow movement speed, so as to increase the circulation speed of the airflow in the alcoholization chamber, so as to increase the dehumidification efficiency of the shredded stems. Similarly, when the moisture content of the shredded stems is low and a slow dehumidification control is required at a relatively slow speed, the guide plate can be controlled to reverse to increase the area of ​​the air outlet. In this way, the airflow movement space is increased, and it can be blown to the shredded stems at a relatively stable speed, thereby achieving a relatively slow and stable dehumidification of the shredded stems.

[0019] On this basis, a guide groove is provided on the side of the guide plate facing the air outlet. When the airflow from the air outlet blows along the guide plate, the airflow will enter the guide groove and drive the micro-vortex generator in the guide groove to rotate. Under the disturbance of the micro-vortex generator, the straight-line airflow is divided into multiple branch airflows. These branch airflows are disturbed by the continuously rotating micro-vortex generator and then collide with each other to form vortex airflow. The combined design of the guide plate and the vortex generator not only retains the adjustable function of the traditional guide plate, but also enhances the uniformity of the airflow distribution through the vortex airflow. The spiral winding extension design of the guide groove further optimizes the diffusion effect of the airflow, so that the airflow can cover the entire alcoholization chamber more evenly. In addition, the setting of the micro-vortex generator does not require complex control or drive devices, and can achieve efficient operation only through the energy of the airflow itself, reducing the manufacturing cost and maintenance difficulty of the equipment.

[0020] 2. As a preferred embodiment of the present application, the guide plate is hinged to the plate body, and the guide plate is rotated by pulling the flexible pull rope. The first driving member can easily drive the guide plate, realize the rapid rotation of the guide plate to adjust the direction and size of the air outlet, improve the accuracy of the air outlet control of the air outlet unit, and further improve the alcoholization effect of the alcoholization equipment.

[0047] like Figures 1 to 6 As shown, a stem aging device for aging tobacco stem shreds comprises a bin 1, wherein the bin 1 has an aging chamber 11, wherein the aging chamber 11 is provided with a material shifting mechanism, wherein the material shifting mechanism can shift the stem shreds in the aging chamber 11; the aging device further comprises an air supply unit, wherein the air supply unit comprises a fan 2 and a main air duct 3 and a branch air duct 4 which are interconnected, wherein the branch air duct 4 has an air outlet 41, and the fan 2 supplies air to the branch air duct 4 through the main air duct 3; the air supply unit further comprises a movably mounted air outlet 41; A guide plate 5 and an adjusting mechanism acting on the guide plate 5, the adjusting mechanism comprising a first driving member 6 and a pulling member 7, the first driving member 6 drives the pulling member 7 to drive the guide plate 5 to rotate relative to the branch air duct 4 to adjust the direction and size of the air outlet 41; a guide groove 52 is provided on the side of the guide plate 5 facing the air outlet 41, a micro vortex generator 130 is provided in the guide groove 52, and the micro vortex generator 130 is rotated by the airflow to convert the straight airflow into a spiral vortex airflow.

[0048] The shredded stem alcoholization equipment of the present application comprises a chamber 1 having an alcoholization chamber 11, wherein the alcoholization chamber 11 is provided with a material shifting mechanism and an air supply unit, wherein the material shifting mechanism is used to shift the shredded stems so that the shredded stems can be dispersed, thereby reducing the probability of the shredded stems agglomerating into a mass, increasing the contact area between the shredded stems and the outside world, and increasing the alcoholization uniformity of the shredded stems; meanwhile, the air supply unit is used to provide airflow to the shredded stems in the alcoholization chamber 11, so that the shredded stems dispersed by the material shifting mechanism can evenly reduce their own moisture content under the action of the airflow until the alcoholization standard is reached. During the operation of the air supply unit, the fan 2 delivers air flow into the main air duct 3, and the air flow is discharged from the air outlet 41 after passing through the main air duct 3 and the branch air duct 4 in sequence. Since the air outlet 41 is provided with a guide plate 5, the guide plate 5 can guide the air flow discharged from the air outlet 41, and the shredded stems are dispersed in various parts of the alcoholization chamber 11 under the action of the material-dispensing mechanism. The guide plate 5 can rotate relative to the branch air duct 4, so as to continuously guide the air flow discharged from the air outlet 41 to various parts of the alcoholization chamber 11, so that the shredded stems evenly distributed in the alcoholization chamber 11 can be evenly affected by the air flow, thereby achieving uniform dehumidification of the shredded stems; that is, the present application achieves uniform distribution of the shredded stems in the alcoholization chamber 11 through the cooperation of the material-dispensing mechanism and the air outlet unit, and evenly supplies air to the evenly distributed shredded stems, thereby improving the alcoholization effect of the shredded stems in many aspects. In addition, for some shredded stems with a high moisture content, in order to speed up the alcoholization efficiency, it is necessary to increase the airflow input in the early stage of the alcoholization process to achieve rapid dehumidification. When the power of the fan 2 is constant, the first driving member 6 can drive the pulling member 7 to move, and drive the guide plate 5 to rotate, so that the guide plate 5 rotates in the direction of reducing the size of the air outlet 41, reducing the air outlet area at the air outlet 41, so that the gas in the branch air duct 4 must be pumped out at a faster speed under the limitation of a smaller movement space, so as to increase the airflow movement speed, so as to increase the circulation speed of the airflow in the alcoholization chamber 11, so as to increase the dehumidification efficiency of the shredded stems. Similarly, when the moisture content of the shredded stems is low and a slow dehumidification control is required at a relatively slow speed, the guide plate 5 can be controlled to reverse to increase the area of ​​the air outlet 41. In this way, the airflow movement space is increased, and it can be blown to the shredded stems at a relatively stable speed, thereby achieving a relatively slow and stable dehumidification of the shredded stems.

[0049] On this basis, a guide groove 52 is provided on one side of the guide plate 5 facing the air outlet 41. When the airflow of the air outlet 41 blows along the guide plate 5, the airflow will enter the guide groove 52 and drive the micro-vortex generator 130 in the guide groove 52 to rotate. Under the disturbance of the micro-vortex generator 130, the straight-line airflow is divided into multiple branch airflows, which are disturbed by the continuously rotating micro-vortex generator 130, and then collide with each other to form a vortex airflow. The combined design of the guide plate 5 and the micro-vortex generator 130 not only retains the adjustable function of the traditional guide plate 5, but also enhances the uniformity of the airflow distribution through the vortex airflow. The spiral winding extension design of the guide groove 52 further optimizes the diffusion effect of the airflow, so that the airflow can cover the entire alcoholization chamber 11 more evenly. And the setting of the micro-vortex generator 130 does not require complex control or driving devices, and can achieve efficient operation only through the energy of the airflow itself, reducing the equipment manufacturing cost and maintenance difficulty.

[0050] Figure 2 The arrow X in the middle indicates the flow path of the airflow. At this time, the guide plate 5 and the plate body 42 form an angle, and the airflow moves in the extension direction of the guide plate 5 under the guidance of the guide plate 5. Figure 4 The arrow Y in the middle indicates the flow path of the airflow. At this time, the guide plate 5 is parallel to the plate body 42 , and the airflow moves in the extending direction of the guide plate 5 under the guidance of the guide plate 5 . Figures 1 to 4 The guide plate 5 is only schematically drawn in the figure. The present application does not limit the number of the guide plates 5. In a preferred embodiment, the guide plates 5 are multiple and are arranged around the air outlet 41, that is, the guide plates 5 surround the air outlet 41 into a relatively closed area, which can better achieve the reduction and expansion of the air outlet 41 through the bending of the guide plates 5.

[0051] As a preferred implementation of the present application, Figure 5 , Figure 6 As shown, the micro vortex generator 130 includes a fixed rotating shaft 1301 and a vortex blade 1302 that can rotate around the fixed rotating shaft 1301, and the vortex blade 1302 has a vortex guide surface facing the air outlet direction. The vortex blade 1302 rotates around the fixed rotating shaft 1301 under the action of the airflow to form a spiral vortex airflow.

[0052] Such a configuration improves the airflow conversion efficiency. The vortex guide surface design of the vortex blade 1302 can efficiently convert the straight airflow into a spiral vortex airflow, thereby improving the diffusion effect of the airflow. It also has a high structural stability. The fixed shaft 1301 ensures the stable operation of the vortex blade 1302 under high-speed airflow, avoiding performance degradation caused by vibration or deviation. In addition, the vortex blade 1302 is driven to rotate by the energy of the airflow itself, without the need for an additional power device, thereby reducing the energy consumption of the equipment.

[0053] As a preferred embodiment of the present application, Figure 5 As shown, the guide groove 52 spirally extends from a side close to the air outlet to a side away from the air outlet, and the number of the micro vortex generators 130 is multiple and arranged at intervals in the guide groove 52.

[0054] The spiral winding extension design of the guide groove 52 allows the airflow to diffuse in multiple directions, further expanding the coverage of the airflow. The vortex airflow intensity is adjustable: multiple micro-vortex generators 130 are arranged at intervals in the guide groove 52, and the intensity and distribution of the vortex airflow can be adjusted according to demand to meet the aging requirements of different stems. Compact structure and easy maintenance: The integrated design of the guide groove 52 and the micro-vortex generator 130 simplifies the equipment structure and is easy to disassemble and maintain.

[0055] As a preferred embodiment of the present application, Figures 1 to 4 As shown, the branch air duct 4 is surrounded by a plate body 42, the guide plate 5 is hinged to the plate body 42, the first driving member 6 is installed on the warehouse body 1, and the pulling member 7 is a flexible pulling rope extending along the plate body 42. The first driving member 6 drives the flexible pulling rope to tighten to drive the guide plate 5 to rotate in the direction of reducing the angle with the plate body 42.

[0056] The guide plate 5 is hinged to the plate body 42, and the guide plate 5 is rotated by pulling the flexible pull rope. The first driving member 6 can easily drive the guide plate 5 to achieve rapid rotation of the guide plate 5 to adjust the direction and size of the air outlet 41, thereby improving the accuracy of the air outlet control of the air outlet unit and further improving the alcoholization effect of the alcoholization equipment.

[0057] As a preferred embodiment of this implementation, Figure 2 , Figure 4 As shown, the guide plate 5 is provided with a connecting portion 51 , and the plate body 42 is provided with a steering plate 8 at the end close to the air outlet 41 . The steering plate 8 is provided with a through hole, and the flexible pulling rope is passed through the through hole and connected to the connecting portion 51 .

[0058] The connection portion 51 is provided to provide a connection position for the flexible pull rope, which can increase the connection stability between the flexible pull rope and the guide plate 5; the deflector plate 8 is provided to change the extension direction of the flexible pull rope, so that it extends toward the guide plate 5, so as to provide accurate pulling force for the guide plate 5 and provide stability guarantee for the rotation of the guide plate 5. On this basis, the through hole provided in the deflector plate 8 plays a certain role in limiting the flexible linkage rope and preventing the flexible linkage rope from shifting.

[0059] As a preferred example under this embodiment, it also includes an elastic reset member arranged between the guide plate 5 and the plate body 42, and the elastic reset member can drive the guide plate 5 to rotate in the direction of increasing the angle between the guide plate 5 and the plate body 42.

[0060] The present application provides an elastic reset member between the guide plate 5 and the plate body 42, so that the guide plate 5 can flexibly adjust the direction and size of the airflow under the action of the adjustment mechanism. The elastic reset member can drive the guide plate 5 to rotate in the direction of increasing the angle with the plate body 42, thereby realizing dynamic adjustment of the airflow and meeting the different airflow requirements of stems of different types and moisture contents. Specifically, the elastic reset member can be made of a material with elastic recovery ability such as a spring. When the guide plate 5 rotates under the action of the adjustment mechanism, the elastic reset member will be compressed or stretched. When the adjustment mechanism stops working, the elastic reset member will return to its original state, thereby driving the guide plate 5 back to its initial position.

[0061] As another preferred example under this embodiment, a penetration pipe is provided on the inner wall of the plate body 42, and the inside of the penetration pipe is hollow to form a penetration cavity for the flexible pull rope to pass through. By providing the penetration pipe on the inner wall of the plate body 42, the flexible pull rope can be smoothly passed through, thereby realizing flexible adjustment of the guide plate 5. This design can flexibly adjust the conveying direction and size of the airflow according to actual needs, ensure full coverage of the shredded stems, and improve the aging effect.

[0062] Specifically, the inside of the threading pipe is hollow, forming a threading cavity for the flexible pull rope to be threaded, so that the flexible pull rope can move smoothly in the pipe, driving the guide plate 5 to adjust. As another preferred example under this embodiment, a plurality of fixing buckles are arranged on the inner wall of the plate body 42 at intervals, and threading grooves are formed between the fixing buckles and the plate body 42, and the flexible pull ropes are threaded through the threading grooves in sequence.

[0063] By setting a fixed buckle on the inner wall of the plate body 42, the flexible pull rope can be smoothly inserted, thereby realizing flexible adjustment of the guide plate 5. This design can flexibly adjust the conveying direction and size of the airflow according to actual needs, ensure the full coverage of the stems, and improve the aging effect. The flexible pull rope is inserted through the insertion grooves in sequence, thereby realizing the adjustment of the guide plate 5. This design provides multiple implementation methods, ensuring the adaptability and flexibility of the equipment.

[0064] As a preferred embodiment of the present application, Figure 1 , Figure 3 As shown, the silo body 1 is a hollow cylindrical structure, the main air duct 3 is annular and arranged at the top of the silo body 1, and the branch air ducts 4 are multiple and arranged at intervals at the bottom of the main air duct 3.

[0065] Specifically, the hollow cylindrical structure of the chamber 1 allows the airflow to form an annular flow path inside the chamber 1, so that the airflow can be more evenly distributed in all corners of the alcoholization chamber 11. In addition, the design of the annular main air duct 3 and the plurality of branch air ducts 4 allows the airflow to enter the alcoholization chamber 11 from multiple directions, thereby effectively covering each part of the shredded stems. This design can ensure that the shredded stems are evenly affected by the airflow during the alcoholization process, avoiding the problem of slow decrease in moisture content of some shredded stems due to insufficient airflow coverage.

[0066] As a preferred embodiment of the present application, Figure 1 , Figure 3 As shown, the air supply unit further includes a return air duct 9 , which is connected to the air suction end of the fan 2 and has a return air port 91 located at the bottom of the bin body 1 .

[0067] The return air duct 9 is connected to the air suction end of the fan 2, and a return air port 91 is set at the bottom of the warehouse body 1. Through the return air duct 9, the airflow at the bottom of the warehouse body 1 can be reintroduced into the fan 2 to achieve the recycling of the airflow. This design helps to improve the utilization efficiency of the airflow and reduce energy consumption, while ensuring that the airflow in the warehouse body 1 is evenly distributed, and further optimizes the alcoholization effect of the shredded stems. Specifically, the return air duct 9 can be made of high temperature resistant and corrosion resistant materials to adapt to the high temperature and corrosive gases that may be generated during the alcoholization process. The setting position of the return air port 91 should take into account the flow path of the airflow in the warehouse body 1 to ensure that the airflow at the bottom can be effectively recovered. In addition, the diameter and length of the return air duct 9 also need to be designed according to the air suction capacity of the fan 2 and the size of the warehouse body 1 to ensure smooth return of the airflow.

[0068] By adding the return air duct 9, the present application can effectively solve the problems of low airflow utilization efficiency and high energy consumption in the prior art. At the same time, the design of the return air duct 9 makes the airflow distribution in the bin 1 more uniform, avoiding the problem of inconsistent alcoholization effect of the cut stems due to uneven airflow coverage. Therefore, the present application improves the alcoholization efficiency and effect while also reducing the production cost, and has significant practical value.

[0069] As a preferred embodiment of the present application, Figure 1 , Figure 4 As shown, the material dispensing mechanism includes a second driving member 10, a rotating shaft 101 extending vertically inside the bin body 1, and a material dispensing plate 110 arranged on the rotating shaft 101. A plurality of material dispensing plates 110 are arranged at intervals along the extension direction of the rotating shaft 101. The second driving member 10 drives the rotating shaft 101 to rotate to drive the material dispensing plate 110 to rotate in the alcoholization chamber 11 to dispense materials.

[0070] The material-digging mechanism realizes the effective diversion of the stems in the alcoholization chamber 11 by providing the second driving member 10, the rotating shaft 101 and the diverting plate 110. The second driving member 10 drives the rotating shaft 101 to rotate, and the rotating shaft 101 drives the diverting plate 110 to rotate and divert the stems in the alcoholization chamber 11, thereby ensuring that the stems are uniformly stressed and fully alcoholized during the alcoholization process. The vertical extension design of the rotating shaft 101 enables the diverting plate 110 to cover different heights of the alcoholization chamber 11, ensuring that each layer of stems can be evenly processed.

[0071] As a preferred embodiment of this implementation, Figure 1 , Figure 3 As shown, the material shifting plate 110 includes a first plate body 1101 connected to the rotating shaft 101 and a second plate body 1102 connected to the first plate body 1101. The material shifting mechanism also includes a push-pull member acting on the second plate body 1102. The push-pull member can drive the second plate body 1102 to move in a first movement direction away from the first plate body 1101 and in a second movement direction close to the first plate body 1101, respectively, thereby lengthening or shortening the material shifting plate 110.

[0072] The design of the material-dividing plate 110 with adjustable length solves the problem that the traditional fixed-length material-dividing plate 110 is difficult to adapt to different volumes and different types of shredded stems, and improves the uniformity of material diversion. For example, when the volume of shredded stems placed in the alcoholization chamber 11 is large, the second plate 1102 can be pushed by the push-pull member to extend the length of the material-dividing plate 110 so that it can cover more volume of shredded stems, thereby achieving all-round coverage of the shredded stems, reducing the probability of being unable to achieve uniform turning of the shredded stems due to the limited length of the material-dividing plate 110, ensuring the uniformity of dehumidification of the shredded stems, and helping to improve the dehumidification effect of the shredded stems. When the volume of shredded stems placed in the aging chamber 11 is small, the second plate 1102 can be pulled along the second direction by the push-pull member to shorten the length of the material stripping plate 110 so that the material stripping plate 110 can cover all the shredded stems. In this way, the distance between the center of gravity of the material stripping plate 110 and the rotating shaft 101 is shortened, and the rotating shaft 101 only needs a small driving force to drive the material stripping plate 110 to rotate to drive the shredded stems.

[0073] The push-pull member can be realized by a variety of methods such as a hydraulic cylinder, a pneumatic cylinder or an electric push rod. The hydraulic cylinder and the pneumatic cylinder can provide a large push and pull force, and are suitable for occasions with a large load, while the electric push rod has the advantages of a simple structure and convenient control. Specifically, the push-pull member can be dynamically adjusted according to the actual situation of the stems through the control system to ensure that the length change of the material-diverting plate 110 can be accurately controlled to achieve the best aging effect.

[0074] As a preferred example under this embodiment, Figure 1 , Figure 3As shown, the alcoholization equipment also includes a tray 120 for shredded stems and a third driving member 1201 acting on the tray 120. The tray 120 is located at the bottom of the warehouse body 1 and is provided with a through hole in the middle for the rotating shaft 101 to pass through. The third driving member 1201 can drive the tray 120 to rotate in the direction opposite to the direction of rotation of the rotating shaft 101.

[0075] In this technical solution, the tray 120 is designed to support the shredded stems so that they remain stable during the alcoholization process. Through the action of the third driving member 1201, the tray 120 can rotate in the opposite direction to the rotation axis 101, so that the shredded stems are evenly turned and exposed in the alcoholization chamber 11. This design ensures that the airflow can evenly cover the surface of the shredded stems, avoiding the problem of inconsistent alcoholization effects caused by uneven airflow coverage. Since the tray 120 and the rotation axis 101 rotate in the opposite direction, the shredded stems on the tray 120 can be moved faster under the action of the moving plate, and the uniform distribution of the shredded stems can be quickly achieved.

[0076] Furthermore, the third driving member 1201 can be in various forms, such as motor drive, hydraulic drive or pneumatic drive. Specifically, the motor drive is more common, and the motor drives the gear or belt transmission device to drive the tray 120 to rotate. The hydraulic drive realizes the rotation of the tray 120 through the cooperation of the hydraulic pump and the hydraulic motor. The pneumatic drive uses the combination of the cylinder and the pneumatic motor to complete the rotation of the tray 120.

[0077] Through the above design, the shredded stem alcoholization equipment of the present application can effectively solve the problems existing in the prior art, such as limited airflow regulation, uneven airflow coverage, and poor equipment adaptability. The self-rotating design of the tray 120 not only improves the alcoholization uniformity of the shredded stems, but also enhances the adaptability and versatility of the equipment, and can better meet the alcoholization requirements of shredded stems of different types and different moisture contents. As a result, the efficiency and effect of the alcoholization of shredded stems are further improved, ensuring the quality of the final tobacco product.

[0078] It should be noted that the adjustment mechanism of the present application can be arranged on both sides of the guide plate 5 to drive the guide plate 5 to rotate in different directions, such as Figure 2 , Figure 4 As shown, adjustment mechanisms are provided on both sides of the guide plate 5 to drive the guide plate 5 to rotate in different directions respectively.

[0079] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0080] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0081] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
