Description

Technical Field

[0001] This utility model relates to the field of tobacco processing, and in particular to an integrated device for flavoring and drying tobacco shreds. Background Technology

[0002] As tobacco quality continues to improve, consumers' demands are no longer limited to the aroma of the tobacco itself, placing higher requirements on tobacco production. Adding a certain proportion of flavorings during the tobacco production process, and applying them evenly to the tobacco shreds, can diversify product styles, improve sensory experience, and meet the high demands for diverse experiences and sensory perception. Since flavorings are usually sprayed in a gas-liquid mixture, and tobacco shreds themselves contain moisture, the tobacco shreds need to be dried after applying the flavorings to remove excess moisture, facilitating preservation and enhancing the aroma and taste of the tobacco.

[0003] In existing technology, the two stages of flavoring addition and drying are carried out in separate equipment. After the flavoring is added, the tobacco is transferred to the drying setting. The transfer process causes the tobacco to be exposed to the air for a long time, which increases the humidity and causes the aroma to dissipate, making it difficult to achieve the desired flavoring effect. Utility Model Content

[0004] In view of this, in order to solve at least one of the aforementioned technical problems, this utility model provides an integrated device for flavoring and drying tobacco shreds.

[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0011] The flavoring nozzle (8) is set on the feed hood (1) and faces the flavoring area (01) for spraying flavoring liquid onto the tobacco in the flavoring area (01);

[0012] The ventilation assembly is used at least to provide airflow into the interior cavity of the cylinder (3);

[0013] The heating device (5) is located outside the cylinder (3) and corresponds to the position of the drying zone (02).

[0014] Among them, the inner diameter of the flavoring zone (01) is smaller than the inner diameter of the drying zone (02);

[0015] The outer diameter of the cylinder (3) is uniform from the feed end to the discharge end.

[0018] Among them, multiple guide plates (34) are provided on the inner wall of the drying zone (02) near the discharge end. The discharge port is close to the lower part of the discharge end. The guide plates (34) extend in a direction away from the flavoring zone (01) and are inclined relative to the axial direction of the cylinder (3).

[0019] Among them, sealing rings are respectively provided between the cylinder (3) and the feed hood (1) and the discharge hood (7), and the cylinder (3) slides against the sealing rings.

[0020] Among them, two rolling rings (35) are axially spaced on the outer periphery of the cylinder (3), and the support drive assembly (4) includes a frame, a support roller, a retaining roller and a reducer. The support roller, the retaining roller and the reducer are all connected to the frame.

[0021] The cylinder (3) is mounted on the support roller via the rolling ring (35), and the retaining roller clamps the rolling ring (35) from both sides of the axial direction;

[0022] The speed reducer is connected to the cylinder (3) for driving the cylinder (3) to roll.

[0023] The frame includes outriggers, an adjustment mechanism, and a support platform. Rollers, guide rollers, and a speed reducer are all connected to the support platform.

This integrated device seamlessly connects flavoring and drying, creating a new process that allows flavored tobacco shreds to directly reach the drying zone without auxiliary equipment. This process saves time spent in prolonged contact with air after flavoring, reducing flavoring loss and minimizing the need for additional equipment connections, resulting in a highly efficient integrated system.

[0034] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation method, structure, features, and effects of an integrated device for flavoring and drying tobacco shreds proposed according to this utility model.

[0035] like Figure 1-2 As shown, this utility model embodiment provides an integrated device for flavoring and drying tobacco shreds, comprising:

[0036] 1. Feed hood; 3. Cylinder; 4. Support and drive assembly; 5. Heating device; 7. Discharge hood; 8. Fragrance nozzle; and 9. Ventilation assembly.

[0037] The cylinder 3 includes a feeding end and a discharging end, and the inner cavity of the cylinder 3 includes a flavoring zone 01 extending to the feeding end and a drying zone 02 extending to the discharging end.

[0038] The feed hood 1 and the discharge hood 7 are respectively installed at the feed end and discharge end of the cylinder 3. The feed hood 1 is provided with a feed port for feeding materials, and the discharge hood 7 is provided with a discharge port for discharging materials.

[0039] The cylinder 3 is connected to the support drive assembly 4. The feed end of the cylinder 3 is higher than the discharge end. The support drive assembly 4 is used to drive the cylinder 3 to roll.

[0040] The flavoring nozzle 8 is mounted on the feed hood 1 and faces the flavoring zone 01, and is used to spray flavoring liquid onto the tobacco in the flavoring zone 01;

[0041] The ventilation assembly is used at least to provide airflow into the interior cavity of the cylinder 3;

[0042] The heating device 5 is located outside the cylinder 3 and corresponds to the position of the drying zone 02.

[0043] The tobacco shreds can be of various types, such as thin sheet tobacco shreds. The cylinder 3 is an approximately cylindrical hollow structure, including an inner cavity extending through the feed end and the discharge end, which are the two ends of the cylinder 3 along its axial direction. The outer diameter of the cylinder 3 is uniform, and the inner cavity is used to pass the tobacco shreds. The flavoring zone 01 and the drying zone 02 are two areas arranged axially within the inner cavity of the cylinder 3. It can be understood that the flavoring zone 01 and the drying zone 02 are not two independent areas; they are connected inside the cylinder 3 and constitute the functional area division of the entire inner cavity of the cylinder 3. The flavoring zone 01 ensures uniform application of flavorings, while the drying zone 02 is used for low-temperature heating to promote flavoring absorption, remove moisture, and ensure stable moisture content. Based on the characteristics of the tobacco shreds and production capacity, the length and cylinder diameter of the flavoring zone 01 and the drying zone 02 are determined to ensure reasonable and efficient application of flavorings and drying of moisture. For example, the lengths of the flavoring zone 01 and the drying zone 02 can be the same, or, when the moisture content of the tobacco shreds is high, the length of the drying zone 02 can be increased.

[0044] The feed hood 1 is a transition and shielding component located on the outside of the feed end of the cylinder 3. The feed hood 1 has a feed inlet, allowing the cylinder 3 to communicate with the outside environment. The feed inlet can be a simple opening, connected to a feed vibrating trough guided from the previous process. The feed vibrating trough extends approximately 200mm into the feed inlet, allowing the tobacco to be evenly and continuously fed into the cylinder 3 through its action. Alternatively, in some embodiments, a feed hopper can be extended outward from the feed inlet for centralized batch feeding.

[0045] The discharge hood 7 is a transition and shielding component located on the outside of the discharge end of the cylinder 3. The discharge hood 7 has a discharge port, which allows the cylinder 3 to communicate with the outside world. The discharge port can be a simple opening, connected to a cloth curtain to prevent the tobacco from scattering when discharged, allowing the tobacco to be conveyed to the next process more smoothly.

[0046] The support drive assembly 4 supports the cylinder 3 and drives it to rotate, allowing the tobacco to tumble and fall inside the cylinder 3, which helps with the spraying of spices and even drying. The support drive assembly 4 also supports the feed hood 1, heating device 5, discharge hood 7, ventilation assembly, etc., and is the basic support equipment located at the bottom. After the cylinder 3 is installed with the support drive assembly 4, the axis of the inner cavity of the cylinder 3 is inclined, that is, the feed end is higher than the discharge end. As the cylinder 3 rotates, the tobacco tumbles and moves towards the discharge port.

[0047] Heating device 5 is used to dry the tobacco shreds after the flavoring is added. Heating device 5 is located on the outside of cylinder 3, with a certain gap between it and cylinder 3, such as a gap of 30-50mm or 40mm. This gap ensures that the heating is a baking process, preventing excessively high temperatures on the sidewalls of cylinder 3 and thus guaranteeing uniform heating at low temperatures. Heating device 5 can be installed on the outside of cylinder 3 in various ways, such as in a portion of the bottom of cylinder 3, or around the circumference of cylinder 3, reducing the difficulty of installation and power consumption.

[0048] The output end of the flavoring nozzle 8 is tilted toward the flavoring zone 01, so that the liquid flavoring can be sprayed into the flavoring zone 01 and onto the inner wall of the flavoring zone 01, and then onto the tobacco that is rotating with the cylinder 3.

[0049] The ventilation components can have various ventilation forms, such as extracting airflow from the discharge end of the cylinder 3 to remove moisture, or supplying hot air to the feed end to achieve auxiliary heating. More detailed examples will be given later.

[0050] This utility model proposes an integrated device for flavoring and drying tobacco shreds. It primarily utilizes flavoring nozzles at the feed end to evenly apply flavoring agents to the tobacco shreds. As the cylinder rotates, the tobacco shreds repeatedly tumble within the cylinder, ensuring even adhesion of the flavoring agents to their surface. Moving along the cylinder's tilt, the tobacco shreds enter the drying zone, where a low-temperature drying process promotes flavoring absorption and balances moisture content. Ventilation components remove excess moisture during drying. This integrated device seamlessly connects flavoring and drying, creating a new process that allows flavored tobacco shreds to directly reach the drying zone without auxiliary equipment. This process saves time spent in prolonged contact with air after flavoring, reduces flavoring loss, and minimizes the need for additional equipment connections, making it a highly efficient integrated device.

[0051] In one embodiment, the inner diameter of the flavoring zone 01 is smaller than the inner diameter of the drying zone 02.

[0052] like Figure 2 As shown, the flavoring zone 01 and the drying zone 02 are coaxially arranged. At the junction with the drying zone 02, a gradually expanding conical area is used for connection, thus achieving a smooth transition of the support surface. This prevents the tobacco from standing up or piling up at the junction due to a sudden drop in the support surface, which would affect the conveying process. The reduced inner diameter of the flavoring zone 01 is due to the need to ensure the same flow rate of tobacco for flavoring and drying. If there is too little tobacco in the flavoring zone 01, the flavoring agent will be sprayed onto the inner wall of the flavoring zone 01, resulting in low utilization and reduced flavoring effect. Conversely, if there is too much tobacco in the drying zone 02, the tobacco will accumulate on the inner wall of the drying zone 02, affecting the drying effect. Therefore, reducing the inner diameter of the flavoring zone 01 ensures that the tobacco is more concentrated within the flavoring zone 01 and covers the inner wall of the flavoring zone 01, achieving full utilization of the flavoring agent. Furthermore, the narrower flavoring zone 01 allows for a higher frequency of tobacco tumbling, resulting in more and more even contact with the flavoring agent.

[0053] The outer diameter of cylinder 3 is uniform from the inlet to the outlet. This allows cylinder 3 to be stably installed on the support drive assembly 4. The design of cylinder 3 is simple, and the equipment is easy to maintain. To reduce the inner diameter of the fragrance-adding zone 01, a double-layer cylinder can be set in the fragrance-adding zone 01. That is, an inner cylinder is set at the corresponding position of the fragrance-adding zone 01 inside the cylindrical outer cylinder, thus forming the fragrance-adding zone 01. This makes cylinder 3 lightweight, easy to drive and maintain. At the same time, the outer cylinder can be mass-produced, and only different inner cylinders need to be produced according to the inner diameter requirements of the fragrance-adding zone 01, reducing production costs. In addition, it also makes cylinder 3 have better heat preservation performance and reduces energy consumption. The degree to which the inner diameter of the fragrance-adding zone 01 is smaller than the inner diameter of the drying zone 02 can be set as needed. For example, the inner diameter of the fragrance-adding zone 01 can be 85%-60% of the inner diameter of the drying zone 02.

[0054] In one embodiment, the inner wall of the flavoring zone 01 is connected with a plurality of flavoring zone lifting plates 31 and rake nails 32, with the flavoring zone lifting plates 31 being closer to the feed end than the rake nails 32.

[0055] More specifically, such as Figure 2 As shown, the flavoring zone 01 further includes a turning zone 011 and a dispersing zone 012, which are arranged from the feed end to the discharge end. Multiple lifting plates 31 are arranged in the turning zone 011, spaced apart circumferentially and staggered axially. Rake nails 32 are staggered axially and circumferentially arranged in the dispersing zone 012.

[0056] During production, tobacco shreds enter the inner cavity of the cylinder 3 through the feed inlet. The tobacco shreds are lifted to a certain height by the flavoring plate 31 in the flavoring zone and then fall. The flavoring nozzle 8 applies flavoring to the tobacco shreds, resulting in more and more even contact between the tobacco shreds and the flavoring. The cylinder 3 rolls, carrying the tobacco shreds to the dispersing zone 012. After being loosened by the rake nails 32 in the dispersing zone 012, the flavored tobacco shreds enter the drying zone 02 for drying. This reduces the adhesion between the tobacco shreds, ensuring that the tobacco shreds entering the drying zone 02 are relatively loose and can be dried more effectively.

[0057] Multiple drying zone lifting plates 33 are connected to the inner wall of the drying zone 02. The tangential plane between the drying zone lifting plates 33 and the inner wall of the drying zone 02 has an angle of less than 90 degrees.

[0058] The drying zone lifting plates 33 are inclined in the circumferential direction of the inner wall of the drying zone 02. In other words, the drying zone lifting plates 33 do not extend towards the axis but are offset, and they extend obliquely towards the moving direction of the inner wall of the drying zone 02. This increases the carrying capacity of the drying zone 02, allowing the tobacco to be carried obliquely upwards from the cylinder 3, such as at the 1 o'clock position. This allows the tobacco to have more contact with the cylinder 3, increasing heat utilization and drying efficiency when the coverage area of ​​the heating device 5 is limited. Simultaneously, the longer falling distance of the tobacco from the 1 o'clock position increases the contact time between the tobacco and the hot air in the embodiment where hot air is provided at the feed end, thus improving the drying effect. Multiple drying zone lifting plates 33 are arranged at intervals in the circumferential direction and staggered in the axial direction.

[0059] In some embodiments, a plurality of guide plates 34 are provided on the inner wall of the drying zone 02 near the discharge end, the discharge port is close to the lower part of the discharge end, the guide plates 34 extend in a direction away from the flavoring zone 01 and are inclined relative to the axial direction of the cylinder 3.

[0060] Multiple guide plates 34 are installed after the lifting plates 33 in the drying zone, spaced apart in the circumferential direction. The guide plates 34 guide the tobacco shreds, reducing the accumulation of tobacco shreds at the discharge port.

[0061] In some embodiments, sealing rings are respectively provided between the cylinder 3 and the feed hood 1 and the discharge hood 7, and the cylinder 3 slides against the sealing rings.

[0062] The sealing ring is made of a soft material, such as a rubber ring, to reduce noise and ensure sealing performance. The sealing ring can be fixedly mounted on the feed hood 1 / discharge hood 7 and slide against the cylinder body 3. Alternatively, the sealing ring can be fixed to the cylinder body 3 and slide against the feed hood 1 / discharge hood 7. The sealing ring is to prevent leakage of tobacco and spices, protect the processing environment and raw materials, and avoid additional losses.

[0063] In one embodiment, two rolling rings 35 are axially spaced along the outer periphery of the cylinder 3, such as... Figure 2 As shown, rolling rings 35 can be installed near the feed end and the discharge end, respectively. The support drive assembly 4 includes a frame, support rollers, guide rollers, and a reducer, all of which are connected to the frame. The cylinder 3 is mounted on the support rollers via the rolling rings 35, and the guide rollers clamp the rolling rings 35 from both axial sides. The reducer is driven by the cylinder 3 to drive its rotation.

[0064] Four rollers are installed on the frame, with two rollers in each group corresponding to one rolling ring 35. The two rollers in the same group are spaced apart in the width direction of the frame so that the rolling ring 35 is supported by rolling on both sides of the bottom. The guide roller rolls against the rolling ring 35 in the axial direction, thereby ensuring the axial stability of the cylinder 3.

[0065] In one embodiment, the frame includes support legs, an adjustment mechanism, and a support platform. Rollers, guide wheels, and a speed reducer are all connected to the support platform. The support legs are located below the support platform and are connected to the support platform through the adjustment mechanism, which is used to drive the support platform to rise and fall.

[0066] The adjustment mechanism can specifically be a telescopic hydraulic cylinder, with four outriggers corresponding to the four corners of the support platform. Specifically, the two outriggers at the discharge end of the cylinder 3 are rotatably connected to the support platform, while the two outriggers at the feed end of the cylinder 3 are connected to the support platform via telescopic hydraulic cylinders. By controlling the extension and retraction of the hydraulic cylinders, the tilt angle of the support platform can be adjusted. Alternatively, in some embodiments, the four outriggers are connected to the four corners of the support platform via telescopic hydraulic cylinders, thereby adjusting the tilt angle of the support platform and the overall height of the support platform, which in turn adjusts the height of the cylinder 3 and the feed and discharge ports, facilitating connection with upstream and downstream processes.

[0067] Adjust the tilt angle of the support platform, and then adjust the axial angle of the cylinder 3 to adjust the speed of the tobacco shreds, so as to selectively increase the aroma-adding time and drying time, which can be adjusted according to the feeding speed and needs.

[0068] The ventilation assembly is used to provide airflow into the inner cavity of the cylinder 3. The airflow can be used solely for ventilation to remove moisture, or it can be used for auxiliary heating. Specifically, in one embodiment, the ventilation assembly includes a hot air assembly 2, which is connected to the inner cavity of the cylinder 3 via the feed end and is used to provide hot air into the cylinder 3.

[0069] The hot air assembly 2 further includes a heating duct and a blower. A heating wire is installed in the heating duct, and the blower supplies air towards the heating duct. The heating duct connects to the cylinder 3 via the feed hood 1, thereby supplying high-temperature hot air into the cylinder 3. On one hand, the high temperature enables rapid heating of the inner cavity of the cylinder 3, promoting the absorption efficiency of the fragrance during the spraying stage, i.e., in the fragrance zone 01. On the other hand, the hot air, in conjunction with the heating device 5, achieves dual heating from both inside and outside, resulting in uniform drying and preventing localized water loss due to excessively high temperatures in the heating device 5. This further promotes the absorption of the fragrance and balances the moisture content of the tobacco.

[0070] In some embodiments, an infrared temperature sensor is also provided to detect the wall temperature of the cylinder 3. A temperature transmitter is used, and the air supply of the hot air assembly 2 can be adjusted according to the cylinder wall temperature to achieve closed-loop control.

[0071] In some embodiments, the ventilation assembly further includes a dehumidification assembly 6, which is connected to the inner cavity of the cylinder 3 via the discharge end and is used to discharge moisture from the cylinder 3.

[0072] The dehumidification component 6 specifically includes a fan and an air outlet pipe. The air outlet pipe is connected to the cylinder 3 via the discharge hood 7, and the fan is connected to the air outlet pipe. Airflow is then drawn out from inside the cylinder 3 to expel the moisture generated during drying, improving the drying effect. In some embodiments, a humidity sensor can be installed inside the cylinder 3 to achieve closed-loop control of the start / stop of the dehumidification component 6 or the airflow rate through humidity detection, preventing continuous air extraction from causing a drop in temperature inside the cylinder 3 and affecting drying.

[0073] In one embodiment, the heating device 5 includes a support member and an electromagnetic heating coil. The electromagnetic heating coil is adapted to the bottom contour of the cylinder 3 and is spaced apart from the bottom portion of the cylinder 3. The support member supports the electromagnetic heating coil. The heating device 5 also includes a temperature detection element for detecting the temperature of the cylinder wall of the cylinder 3.

[0074] The support component includes a tray, which has an arc-shaped plate structure. An electromagnetic heating coil is coiled on the tray and positioned close to the bottom of the cylinder 3. The electromagnetic heating coil uses low-temperature drying, which can better preserve the original aroma of the tobacco and the flavorings after flavoring. Low-temperature drying promotes the absorption of flavorings by the tobacco and balances the moisture content of the tobacco, ensuring the output moisture meets process requirements. In some embodiments, the support component can be adjustable as needed. For example, the support component may also include a fixing component and an adjusting component. The fixing component is fixed to the frame, and an adjusting component is provided between the tray and the fixing component. The adjusting component can be a ball joint, multiple longitudinally and transversely connected adjusting rods, a gooseneck tube, or a universal tube. The position of the tray is adjusted through the adjusting component.

[0075] The temperature detection component can be an infrared temperature sensor. By detecting the temperature through the infrared temperature sensor, the electromagnetic heating power can be adjusted. Combined with the moisture detection of the feed and discharge, an effective automatic temperature control system is formed to achieve automatic control of the moisture content of the discharged material.

[0076] In some embodiments, a protective heat-insulating device is provided on the outside of the cylinder 3. The protective heat-insulating device is spaced apart from the cylinder 3 and at least partially covers the outer periphery of the part of the cylinder 3 and the part of the heating device 5 where the electromagnetic heating coil is located. This can better ensure the temperature of the cylinder 3, reduce heat loss, reduce energy consumption, and also reduce burns and positional displacement caused by accidental contact between the cylinder 3 and the heating device 5.

[0077] In one embodiment, the fragrance nozzle 8 is a mixing nozzle, and the input end of the mixing nozzle is used to connect to a compressed air supply device and a fragrance liquid supply device, so that the fragrance liquid is sprayed from the output end.

[0078] This allows compressed air to eject the flavoring liquid onto the tobacco. For example... Figure 3 As shown, the tobacco shreds move circumferentially following the rolling motion of the cylinder 3, achieving spraying in the width direction. Figure 4 As shown, the tobacco shreds move axially along the inclined direction of the cylinder 3 to achieve spraying in the length direction, and then the fragrance liquid spraying trajectory is a spiral motion on the tobacco shreds, so that the tobacco shreds fully contact the fragrance.

[0079] The following describes the tobacco processing process in more detail, in conjunction with the above embodiments:

[0080] The flavoring and drying of tobacco shreds is completed in one piece of equipment. A reducer drives the cylinder 3 to rotate. Tobacco shreds enter the cylinder 3 from the feed end. Flavoring nozzles 8 apply flavorings evenly to the tobacco shreds from the feed end. Flavoring zone baffles 31 carry the tobacco shreds and rotate them evenly within the cylinder 3, ensuring the flavorings are evenly sprayed onto the surface of the tobacco shreds. After flavoring in the flavoring zone 01, the tobacco shreds reach the drying zone 02. Drying zone baffles 33 carry the tobacco shreds and rotate them evenly within the cylinder 3. The drying zone 02 uses electromagnetic heating, which provides stable low-temperature regulation and can quickly heat the cylinder 3. The low temperature promotes flavoring absorption and balances the moisture content of the tobacco shreds. The dried tobacco shreds are then discharged through the discharge end.

[0081] In addition, in some embodiments, the integrated device also includes a controller that can be fixed on the frame of the support drive assembly 4. The controller is connected to the support drive assembly 4, the heating device 5, the fragrance nozzle 8 and the ventilation assembly to control the start and stop, the flow rate and the lifting and lowering of the support platform, such as by adjusting the mechanism.

[0082] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
