Description

Technical Field

[0001] The invention relates to the field of tobacco leaf curing, and in particular to a fast temperature-controlling air-drying tobacco baking device. Background Art

[0002] Non-burning cigarettes produce smoke by heating tobacco raw materials instead of burning them, satisfying smokers' nicotine needs. At the same time, the smoke produced by non-burning cigarettes contains significantly fewer harmful substances, making them more health-friendly to smokers than traditional cigarettes. However, in the existing technology, the tobacco raw materials for non-burning cigarettes are basically in the form of tobacco flakes, particles, or a mixture of stems and shredded tobacco, and shredded tobacco is rarely used directly as a raw material. This is because the low-temperature heating method makes it difficult for the tobacco shreds themselves to fully volatilize their own flavor and aroma. Therefore, non-burning cigarettes mainly rely on the later addition of flavoring to the raw materials to provide the aroma and flavor of the smoke, which also results in a significant difference in the aroma experience provided by them from traditional cigarettes, making the aroma unnatural and less satisfying, and thus they have never been able to replace the market position of traditional cigarettes.

[0003] Compared to flue-cured tobacco, sun-cured tobacco leaves (red and yellow) have the advantage of a naturally high aroma. If these leaves could be cured using a baking method instead of the air-cured method to compensate for the higher irritation and less flavorful taste of sun-cured tobacco, they could be creatively used as raw materials for non-combustion cigarettes, thereby addressing the shortcomings of non-combustion cigarettes in terms of aroma, strength, and unnaturalness. However, since sun-cured tobacco leaves are cured using outdoor lighting and ventilation, research on their curing processes is still lacking. Furthermore, the temperature during the color-setting and tendon-drying stages of the existing three-stage curing process is between 40-70°C, far exceeding the temperature requirements of the air-cured method. Therefore, curing equipment capable of rapid temperature control at each stage is needed to study the curing processes of various sun-cured tobacco varieties. However, existing experimental ovens have a certain operational delay in temperature control, which hinders accurate observation of the appearance changes of tobacco leaves at different temperatures. Summary of the Invention

[0012] A second cavity is provided at both ends of the connecting plate corresponding to the first cavity, and a through hole for plugging the trigger rod is provided on one side of the second cavity corresponding to the trigger rod;

[0013] Hollow blocks are slidably provided in the two second cavities and penetrate to the outside and are arranged opposite to each other. The opposite sides of the two hollow blocks are connected to the inner wall of the second cavity through the second spring.

[0014] The hollow clamping block is open on one side toward the mounting block and a trigger block is fixedly arranged inside the hollow clamping block. The side surface of the trigger block for contacting the trigger rod is in a wedge shape.

[0015] Preferably, the base is detachably embedded with a collection box with a top opening in a corresponding mounting block, and the top surface of the collection box is flush with the bottom surface of the placement groove.

[0016] Preferably, the rack structure further comprises a placement rod with a cigarette holder at the bottom, a handle at one end of the placement rod, and side walls at both ends of the placement rod are respectively provided with limiting holes for inserting limiting blocks and card slots for inserting hollow card blocks.

[0017] Preferably, the adjustment structure includes a mounting bracket provided on the top outside the drying chamber, a driving motor is provided on the top of the mounting bracket to rotate a threaded rod provided in the drying chamber, the top of the mounting bracket is exposed to the outside and connected to the output shaft of the driving motor;

[0018] An insulation board is provided between the drying bin and the regulating bin. Both sides of the insulation board slide vertically with the corresponding chute opened on the bin body. The insulation board is located on both sides of the chute and respectively engages with the threaded rod and the guide rod for sliding engagement. The top of the guide rod is fixed to the top wall of the bin body.

[0019] Preferably, the top of the regulating cavity is further provided with a trigger structure for closing the air duct on the corresponding partition.

[0020] Preferably, the trigger structure includes two equal-height mounting rods that are horizontally slidably arranged below the corresponding partitions, and several sealing blocks for blocking the air duct are arranged between the two mounting rods. When the trigger structure is in a non-working state, the sealing blocks and the air duct are staggered.

[0021] Preferably, the end of the mounting rod close to the drying chamber is located directly above the heat insulation board and is in the shape of a wedge surface that can contact the heat insulation board;

[0022] The end of the mounting rod away from the drying chamber is provided with a bulge, one end of the connecting rod sleeved with the third spring passes through the bulge and is provided with a flange, and the other end is connected to the inner wall of the regulating cavity.

[0023] The present invention works as follows:

[0024] In the initial state, the bracket structure is in a state where the mounting block and the connecting plate are in contact with each other. At the same time, the trigger rod of the mounting block is inserted from the through hole of the connecting plate and the wedge surface of the trigger block is used to make the hollow card block squeeze the second spring and retract into the second cavity.

[0025] Then clamp the tobacco leaves with the tobacco clips and place several tobacco-loaded placement rods in the placement slots:

[0026] The end of the placement rod without a handle is horizontally inserted between the two second cavities of the connecting plate, so that the connecting plate bears the weight of the placement rod end. The placement rod is then pushed horizontally, thereby driving the connecting plate away from the mounting block until the connecting plate drives the support rod and the scraper block to move against the limit plate. At this moment, the end of the placement rod with the handle also moves between the two mounting blocks. During this process, due to the separation of the connecting plate and the mounting block, the trigger block is no longer restricted by the trigger rod. Therefore, the trigger block and the hollow block are temporarily free and pushed into the second cavity by the second spring. The hollow block directly enters the slot on the placement rod, thereby limiting the corresponding end of the placement rod on the connecting plate. At the same time, when the limiting hole of the placement rod reaches the limiting block on the mounting block, the first spring pushes the dial plate, causing the limiting block to enter the limiting hole, thus completing the limiting of the placement rod.

[0027] After all placement rods are installed in all placement slots, the electric pulley drives the base along the track from the adjustment chamber to the drying chamber. The drive motor then drives the threaded rod to rotate, moving the insulation board, which is now located between the heating chamber and the ventilation chamber, downward, so that the insulation board separates the adjustment chamber and the drying chamber. The door is then closed and the baking process begins: the fan draws outside air into the blast chamber through the filter and then into the adjustment chamber. After passing through the partition's air duct, the air enters the heating chamber, where it is heated by the heater and then enters the ventilation chamber. After passing through the partition's air duct, the air enters the drying chamber and is finally blown through the tobacco leaves and discharged from the exhaust port. (If moisture retention is required, a pipe can be installed to connect the exhaust port to the air inlet, thus completing the downward circulation baking operation).

[0028] Staff can observe the appearance of tobacco leaves during different stages of processing (because air-cured tobacco differs from flue-cured tobacco in that the three stages are yellowing, color fixation, and dryness, while air-cured tobacco undergoes a browning phase). If the leaves appear to be small curls, collapsed frames, or large curls, or if the color changes too quickly or too slowly, this indicates that the temperature and humidity settings are inappropriate. However, environmental regulation in the drying chamber has a certain lag, meaning that immediate cooling is not possible. Therefore, when the drying chamber temperature is too high and needs to be cooled, the drive motor drives the threaded rod in the opposite direction, moving the insulation board, currently located between the regulating and drying chambers, to move it between the heating and ventilation chambers. This now connects the drying and regulating chambers, while sealing off the heating and ventilation chambers. Simultaneously, as the insulation board moves upward, it contacts the wedge surface of the mounting rod, overcoming the force of the third spring and pushing the mounting rod horizontally. This, in turn, drives the sealing block to seal the air duct of the regulating chamber partition. Therefore, while the heater regulates its own temperature, air drawn in by the blower enters the drying chamber and exits through the exhaust vent, rapidly lowering the drying chamber temperature. After the temperature in the drying chamber reaches the standard, the heat insulation plate moves down and closes the regulating chamber and the drying chamber again. At the same time, the mounting rod is reset under the action of the third spring, and the baking operation is resumed.

[0029] After the baking is completed, the sealing door is opened and the electric pulley drives the base to move along the track from the drying chamber to the adjustment chamber, and then the tobacco leaves are taken out:

[0030] First, move the paddle on the mounting block to separate the stopper and placement rod. Then, pull the placement rod horizontally outward relative to the mounting block. Simultaneously, the placement rod drives the scraper block via the connecting plate, scraping any impurities (such as crushed tobacco leaves and sand and soil from harvested tobacco leaves) into the collection box. Simultaneously, when the connecting plate contacts the mounting block, the trigger rod contacts the trigger block and hollow retaining block, separating the hollow retaining block from the placement rod. The placement rod is now free and can be removed directly. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A partition 205 is provided at the same height in the regulating chamber 2 and the drying chamber 1. The partition 205 divides the upper and lower parts of the drying chamber 1 into a ventilation chamber 103 and a drying chamber 101. The partition 205 divides the upper and lower parts of the regulating chamber 2 into a heating chamber 203 and a regulating chamber 202.

[0044] The top of the regulating chamber 202 is also provided with a trigger structure for closing the air duct on the corresponding partition 205: it includes two equal-height mounting rods 501 that are horizontally slidably arranged below the corresponding partition 205, and several sealing blocks 502 for blocking the air duct 209 are arranged between the two mounting rods 501. When the trigger structure is in a non-working state, the sealing blocks 502 and the air duct 209 are staggered.

[0045] The end of the mounting rod 501 close to the drying chamber 1 is located directly above the insulation board 405 and is in the shape of a wedge that can contact the insulation board 405; the end of the mounting rod 501 away from the drying chamber 1 is provided with a protrusion, and one end of the connecting rod 504 which is sleeved with the third spring 503 passes through the protrusion and is provided with a flange, and the other end is connected to the inner wall of the adjustment chamber 202.

[0046] The bottom of the regulating chamber 2 is also provided with a blast chamber 208 connected to the regulating chamber 202. The blast chamber 208 is provided with a fan 206 for exhausting air toward the regulating chamber 202. The blast chamber 208 is provided with an air inlet covered with a filter 207. The bottom of the drying chamber 1 is provided with an exhaust port.

[0047] The rack structure 3 includes a base 301 and rails 302 extending into the drying chamber 101 and the adjustment chamber 202 at both ends. The bottom of the base 301 is slidably arranged on the rails 302 via an electric pulley.

[0048] A limiting plate 303 is vertically fixed to one end of the top of the base 301, and several clamping plates 304 are arranged at equal intervals and vertically connected to the limiting plate 303. The gaps between the clamping plates 304 form a placement groove for accommodating cigarette clips. The middle plate surfaces of the limiting plate 303 and the clamping plates 304 are in a filter structure. A collection box 315 with a top opening is detachably embedded at the end of the base 301 away from the limiting plate 303, and the top surface of the collection box 315 is flush with the bottom surface of the placement groove.

[0049] The two side walls of the placement groove away from one end of the limit plate 303 are provided with mounting blocks 305, and the two mounting blocks 305 are provided with a first cavity at the same height, one end of the dial plate 307 passes through the first cavity to the outside, and the other end is vertically provided with a limiting block 306 that passes through the first cavity, and the limiting blocks 306 of the two mounting blocks 305 are arranged opposite to each other and have a wedge-shaped structure; the side of the dial plate 307 facing away from the limiting block 306 is provided with a first spring 308 connected to the inner wall of the first cavity, and the two ends of the mounting block 305 facing the limit plate 303 are vertically provided with trigger rods 312.

[0050] The bottom of the placement groove is slidingly provided with a scraper block 314 that contacts the base 301, and the top of the scraper block 314 is connected to the connecting plate 309 arranged at the same level as the mounting block 305 through a support rod 313. A second cavity is provided at both ends of the connecting plate 309 corresponding to the first cavity, and a through hole 320 for plugging the trigger rod 312 is opened on the side of the second cavity corresponding to the trigger rod 312; hollow card blocks 311 that penetrate to the outside and are arranged oppositely are slidingly provided in the two second cavities, and the back sides of the two hollow card blocks 311 are connected to the inner wall of the second cavity by a second spring 321. The hollow card block 311 is open to one side of the mounting block 305 and a trigger block 322 is fixed inside. The trigger block 322 is wedge-shaped for contacting the side of the trigger rod 312.

[0051] A handle is provided at one end of the placement rod 316 with a cigarette holder 317 at the bottom. The side walls at both ends of the placement rod 316 are respectively provided with a limiting hole 318 for inserting the limiting block 306 and a clamping slot 319 for inserting the hollow clamping block 311.

[0052] The present invention works as follows:

[0053] In the initial state, the bracket structure 3 is in a state where the mounting block 305 and the connecting plate 309 are in contact with each other. At the same time, the trigger rod 312 of the mounting block 305 is inserted from the through hole 320 of the connecting plate 309 and uses the wedge surface of the trigger block 322 to make the hollow clamping block 311 squeeze the second spring 321 and retract into the second cavity.

[0054] Then, the tobacco leaves are clamped by the cigarette clamps and several placing rods 316 loaded with tobacco leaves are placed in the placing grooves:

[0055] The end of the placement rod 316 without a handle is horizontally inserted between the two second cavities of the connecting plate 309, so that the connecting plate 309 bears the weight of the end of the placement rod 316. The placement rod 316 is then pushed horizontally, thereby driving the connecting plate 309 away from the mounting block 305, until the connecting plate 309 drives the support rod 313 and the scraper block 314 to move against the limit plate 303. At the same time, the end of the placement rod 316 with a handle also moves between the two mounting blocks 305. During this process, due to the separation of the connecting plate 309 and the mounting block 305, the trigger block 322 is no longer restricted by the trigger rod 312. Therefore, the trigger block 322 and the hollow block 311 are temporarily free and pushed into the second cavity by the second spring 321. The hollow block 311 directly enters the slot 319 on the placement rod 316, thereby causing the connecting plate 309 to limit the corresponding end of the placement rod 316. At the same time, when the limiting hole 318 of the placement rod 316 reaches the limiting block 306 on the mounting block 305, the first spring 308 pushes the dial plate 307 so that the limiting block 306 enters the limiting hole 318, thus completing the limiting of the placement rod 316.

[0056] After the placement rods 316 are set in all the placement slots, the base 301 is driven by the electric pulley along the track 302 from the adjustment chamber 202 to the drying chamber 101. Then the driving motor 402 drives the threaded rod 403 to rotate, and the heat insulation board 405 located between the heating chamber 203 and the ventilation chamber 103 is moved downward, so that the heat insulation board 405 isolates the adjustment chamber 202 and the drying chamber 101. Then the sealing door is closed to start baking: the fan 206 draws the outside air into the blast chamber 208 through the filter 207 and then blows it into the adjustment chamber 202. After passing through the air duct 209 of the partition 205, it enters the heating chamber 203 and is heated by the heater 204 before entering the ventilation chamber 103. After passing through the air duct 209 of the partition 205, it enters the drying chamber 1 and finally blows through the tobacco leaves and is discharged from the exhaust port (if moisture retention is required, a pipe can be set to connect the exhaust port to the air inlet, thus completing the lower circulation baking operation).

[0057] The staff can observe the changes in the appearance of tobacco leaves in different stages (because air-dried tobacco is different from flue-cured tobacco, the three stages of flue-cured tobacco are yellowing-fixing color-drying, while air-dried tobacco will have a browning stage). If the tobacco leaves have morphological changes such as small rolls, collapsed frames or large rolls, and the color changes are too fast or too slow, it means that the current temperature and humidity are not set properly, but the environmental adjustment of the drying chamber has a certain time lag, such as the inability to achieve immediate cooling. Therefore, when the temperature of the drying chamber is too high and needs to be cooled, the drive motor 402 drives the threaded rod 403 to rotate in the opposite direction, and moves the insulation board 405, which is now located between the regulating chamber 202 and the drying chamber 101, up to between the heating chamber 203 and the ventilation chamber 103. At this time, the drying chamber 101 and the regulating chamber 202 are connected, and the heating chamber 203 and the ventilation chamber 103 are closed. As the heat shield 405 moves upward, it contacts the wedge surface of the mounting rod 501, overcoming the elastic force of the third spring 503 and forcing the mounting rod 501 to move horizontally. This in turn drives the sealing block 502 to seal the air duct 209 of the partition 205 within the regulating chamber 2. Therefore, while the heater 204 regulates its own temperature, air drawn in by the blower 206 blows into the drying chamber 101 and out through the exhaust port, rapidly lowering the temperature of the drying chamber 101. Once the temperature in the drying chamber 101 reaches the desired level, the heat shield 405 moves downward, sealing the regulating chamber 202 and drying chamber 101 again. Simultaneously, the mounting rod 501 returns to its original position under the action of the third spring 503, and the baking process resumes.

[0058] After the baking is completed, the sealing door is opened, and the electric pulley drives the base 301 to move along the track 302 from the drying chamber 101 to the adjustment chamber 202, and then the tobacco leaves are taken out:

[0059] First, the shift plate 307 on the mounting block 305 is moved to separate the stop block 306 from the placement rod 316. The placement rod 316 is then pulled horizontally outward relative to the mounting block 305. Simultaneously, the placement rod 316 drives the scraper block 314 via the connecting plate 309, scraping any impurities (such as crushed tobacco leaves and sand and dirt from harvested tobacco leaves) into the collection box 315. Simultaneously, when the connecting plate 309 contacts the mounting block 305, the trigger rod 312 contacts the trigger block 322 and the hollow block 311, separating the hollow block 311 from the placement rod 316. The placement rod 316 is now free and can be removed directly.

[0060] It should be noted that the present invention can be equipped with a control device to adjust the corresponding working parameters of the heater and the drive motor. The temperature in the drying chamber 101 is monitored by the temperature sensor 102. At the same time, a sealed observation window is provided on the drying chamber 1 or is made of transparent material.
