Description

Technical Field

[0001] The invention relates to the field of tobacco processing, in particular to a tobacco flavoring machine. Background Art

[0002] Flavoring is one of the core processes in the cigarette manufacturing process. Its main task is to apply the flavoring liquid to the tobacco accurately and evenly according to the requirements of the product design, and to ensure that the tobacco absorbs the flavoring liquid stably. Flavoring tobacco plays the role of assisting, stabilizing, supplementing, adding fragrance, and correcting the flavor of cigarette products, giving cigarette products different style characteristics, meeting the different personalized needs of consumers, and thus being loved by consumers. This process is directly related to the sensory quality of cigarette products and is a key link in realizing product value and improving product quality.

[0003] like Figure 1 to Figure 3 As shown, the tobacco flavoring mechanism of the related art includes a copying device and a spray device 6', and the copying device includes a drum 1', a feed part 2' arranged at the feed end of the drum 1', a discharge part 3' arranged at the discharge end of the drum 1', and a bracket 4' for supporting the drum 1'. The drum 1' is installed on the frame 4', and the feed part 2' is higher than the discharge part 3'. The drum 1' can rotate continuously clockwise or counterclockwise along its central axis. A plurality of copying plates 5' are evenly fixed on the inner wall 11' of the drum 1', and each copying plate 5' axially passes through the drum from the feed end of the drum 1' to the discharge end, and each copying plate is parallel to the central axis of the drum 1'. The tobacco shreds are fed into the drum 1' from the feed section 2'. Under the joint action of the rotation of the drum 1' and the shovel board 5', the tobacco shreds are rolled up and down and scattered and travel in a spiral manner with the drum 1' and the shovel board 5'. During the travel, the tobacco shreds are flavored by the spray device 6'. After flavoring, they are discharged from the discharge section 3' and transported to the next process. The spray device 6' continuously applies fragrance liquid to the scattered tobacco shreds. The spray direction of the spray device 6' is toward the inner wall 11' of the drum 1', and the distance from the feed port of the drum 1' is about one-third of the length of the drum. Under the joint action of the rotation of the drum 1' and the shovel board 5', the tobacco shreds are rolled up and down and stirred so that the fragrance liquid is evenly absorbed, completing the flavoring process task.

[0004] The aroma device in the prior art has at least the following problems:

[0005] 1. Since the moisture content of tobacco in the flavoring process is low, a breeze can blow the tobacco. The spray device 6' is installed at the front end of the feed part 2', and the applied fragrance liquid is sprayed from the feed part 2' to the discharge part 3'. The fragrance liquid and part of the tobacco are directly blown to the discharge part 3' at the end of the drum under the spray pressure of the spray device, and adsorbed on the discharge part 3', resulting in tobacco waste and wet mass, thus affecting product quality.

[0006] 2. The atomized fragrance liquid of the existing spray device sweeps over the surface of the tobacco shreds. The spray cone angle Φ of the spray device 6' is small, the impact force on the tobacco shreds is large, and the contact area is small, which is not conducive to the absorption of the tobacco shreds, causing the fragrance liquid to remain on the surface of the tobacco shreds, or volatilize in the internal and external environment of the drum 1', resulting in poor fragrance uniformity, low utilization rate of the fragrance liquid and environmental pollution.

[0007] 3. The copy board 5' is designed to be a flat plate from the feed end to the discharge end of the drum 1' and is parallel to the central axis of the drum 1'. At the feed end, the tobacco is easily thrown back to the feed vibration trough (not shown in the figure) for repeated vibration, causing the tobacco to break; at the discharge end, after the tobacco is flavored in the nozzle spray area, it rolls up and down and is thrown for too long in the drum 1' with the copy board, and the excessive throwing causes the tobacco to break. In addition, the copy board has a poor loosening effect, and the tobacco is scattered in piles, with a small contact area with the atomized fragrance liquid, which is not conducive to the tobacco absorbing the fragrance liquid.

[0008] 4. Due to the poor overall absorption effect of tobacco on atomized fragrance liquid, a large amount of fragrance liquid overflows from the feed port, discharge port and dehumidification system of the drum, especially the low utilization efficiency of volatile substances, resulting in the product's odor intensity and aroma coordination stability deviating from the original design of the product. Summary of the invention

[0009] The present invention aims to provide a tobacco flavoring machine to improve the problem in the related art that tobacco shreds cannot flow smoothly from an inlet end to an outlet end because a copying plate is parallel to the axis of a drum.

[0019] In some embodiments, the distance between the top of one end of the third copy board close to the second copy board and the inner wall is smaller than the distance between the top of one end of the third copy board far from the second copy board and the inner wall.

[0020] In some embodiments, the lifting plate further comprises a fourth lifting plate located downstream of the second lifting plate along the flow direction of the tobacco shreds, and the fourth lifting plate is configured to stir the tobacco shreds after the flavoring liquid is added.

[0021] In some embodiments, the angle between the fourth copy plate and the busbar is smaller than the angle between the first copy plate and the busbar.

[0022] In some embodiments, the copying plate further comprises a fifth copying plate located inside the drum near the outlet end of the drum, and the angle between the fifth copying plate and the busbar is greater than the angle between the second copying plate and the busbar.

[0023] In some embodiments, the rotation direction of the drum is configured so that an end of the copy board adjacent to the inlet end of the drum is located in front of the other end of the copy board.

[0024] In some embodiments, at least one of a spray angle, a spray cone angle, and a spray distance of the nozzle is adjustable.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Figure 4 The schematic diagram of the structure of the tobacco flavoring machine of this embodiment is shown. Figure 5This embodiment shows Figure 4 A schematic structural diagram of a cross section of a drum at AA of a tobacco flavoring machine; Figure 6 Shows Figure 4 Schematic diagram of the structure of the cross section of the roller BB of the tobacco flavoring machine. Figure 7 The schematic diagram of the structure of the tobacco flavoring machine of this embodiment after the drum is flattened is shown.

[0041] Combination Figures 4 to 7 As shown, the tobacco flavoring machine of this embodiment includes a drum 1, a nozzle 6 and a shoveling plate 5. The drum 1 can rotate with its axis as the rotation center; the nozzle 6 is arranged in the drum 1 to spray the fragrant liquid to the tobacco in the drum 1; and the shoveling plate 5 is erected on the inner wall 11 of the drum 1 and extends from the inlet end of the drum 1 toward the inside of the drum 1, and the shoveling plate 5 is arranged obliquely relative to the generatrix 9 of the drum 1.

[0042] like Figure 6 As shown, when the copying plate 5 rotates to the 9 o'clock position, one end of the copying plate 5 close to the inlet end of the drum 1 is higher than the other end of the copying plate 5, so the tobacco can be thrown and dropped successively along the copying plate 5 toward the outlet end of the drum 1, thereby improving the problem of the tobacco of the same copying plate being synchronously thrown and dropped from the inlet end to the outlet end at the same time in the related art.

[0043] In this embodiment, the copy board 5 includes a first copy board 51 and a second copy board 52. The first copy board 51 extends from the inlet end of the drum 1 toward the inside of the drum 1.

[0044] The second copying plate 52 and the first copying plate 51 are arranged side by side along the axial direction of the drum 1 and are located on the inner side of the first copying plate 51. The angle between the second copying plate 52 and the generatrix 9 of the drum 1 is smaller than the angle between the first copying plate 51 and the generatrix of the drum 1.

[0045] The angle between the first copy board 51 and the generatrix 9 of the drum 1 is 30° to 60°. The generatrix 9 of the drum 1 is parallel to the axis of the drum 1, so the angle between the first copy board 51 and the axis of the drum 1 is also 30° to 60°.

[0046] The angle between the second pick plate 52 and the generatrix 9 of the drum 1 is 3° to 10°.

[0047] The nozzle 5 is directed toward the second copying plate 52 to spray the aromatic liquid onto the tobacco shreds thrown by the second copying plate 52 .

[0048] The copying plate 5 further comprises a third copying plate 53 arranged at one end of the second copying plate 52 away from the first copying plate 51, and the distance between the end of the third copying plate 53 away from the inner wall 11 of the drum and the inner wall 11 is greater than the distance between the end of the second copying plate 52 away from the inner wall 11 and the inner wall 11, so as to block the tobacco shreds and / or the aroma liquid that are impacted by the aroma liquid and move toward the outlet end of the drum 1.

[0049] The distance between the top of the end of the third copy board 53 close to the second copy board 52 (the top is also the end away from the inner wall) and the inner wall 11 is smaller than the distance between the top of the end of the third copy board 53 away from the second copy board 52 (the top is also the end away from the inner wall) and the inner wall 11. That is, the front section height H1 of the third copy board 53 is smaller than the rear end height H2.

[0050] The pick-up plate 5 further includes a fourth pick-up plate 54 located downstream of the second pick-up plate 52 along the flow direction of the tobacco shreds. The fourth pick-up plate 54 is configured to stir the tobacco shreds after the aroma liquid is added.

[0051] The included angle between the fourth copy plate 54 and the busbar 9 is smaller than the included angle between the first copy plate 51 and the busbar 9 .

[0052] The pick-up plate 5 also includes a fifth pick-up plate 55 located at the outlet end of the drum 1 near the drum 1, and the angle between the fifth pick-up plate 55 and the busbar 9 is greater than the angle between the second pick-up plate 52 and the busbar 9. The angle between the fifth pick-up plate 55 and the axis of the drum 1 is also 30° to 60°.

[0053] The rotation direction of the drum 1 is configured so that one end of the copy board 5 adjacent to the inlet end of the drum 1 is located in front of the other end of the copy board 5. Figure 7 As shown, the arrow in the figure indicates the rotation direction of the drum 1. In this way, the copy board 5 at the bottom of the drum 1 rotates 90 degrees to reach Figure 6 The 9 o'clock position shown is conducive to transporting the tobacco introduced from the inlet end of the drum 1 toward the discharge end, and is also conducive to completing the scattering and falling of the tobacco before rotating to 12 o'clock.

[0054] The tobacco flavoring machine includes a drum 1 and a copying plate 5 arranged on the inner wall 11 of the drum. The copying plate 5 is composed of at least a first copying plate 51, a second copying plate 52, a third copying plate 53, a fourth copying plate 54, and a fifth copying plate 55. The first copying plate 51, the second copying plate 52, the third copying plate 53, the fourth copying plate 54, and the fifth copying plate 55 are arranged in sequence from the front end to the rear end in the drum 1, and the copying plate 5 is fixed on the inner wall 11.

[0055] Furthermore, the first copying plate 51 is a fast feeding zone, the second copying plate 52 is a flavoring zone, the third copying plate 53 is a material blocking zone, the fourth copying plate 54 is a tobacco stirring and mixing zone, and the fifth copying plate 55 is a fast discharging zone.

[0056] Furthermore, the number of copy boards in the drum 1 is greater than 6 and is evenly distributed on the circumference.

[0057] Furthermore, the front width H1 of the third copy plate 53 is smaller than the rear width H2.

[0058] Preferably, the angle between the lifting plate 5 and the inner wall 11 is 70-110°.

[0059] Preferably, the rotation speed of the drum 1 is 6-15 r / min and can be adjusted by variable frequency.

[0060] Based on this, the first shoveling plate 51 allows the delivered tobacco to enter the drum 1 and then be quickly delivered to the flavoring area, thereby reducing excessive scattering and crushing of tobacco and avoiding tobacco overflow at the feed end of the drum; the second shoveling plate 52 allows the tobacco delivered from the first shoveling plate 51 to be continuously and evenly scattered, thereby improving the uniformity and scattering area of ​​tobacco scattering and allowing gaps to exist between tobacco particles; the third shoveling plate 53 blocks the tobacco and flavoring liquid axially blown toward the discharge end by the spray pressure, and the tobacco scattered by the blocking area absorbs the atomized flavoring liquid axially blown toward the discharge end, thereby avoiding tobacco and The aroma liquid is adsorbed on the discharge cover 3 and / or volatilizes into the internal and external environment of the drum 1, reducing environmental pollution during the aroma addition process; the fourth shoveling plate 54 is used to further tumble, stir and mix the aroma-added tobacco, thereby improving the uniformity and absorption rate of the aroma-added tobacco; the fifth shoveling plate 55 is used to make the fully tumbled and mixed tobacco quickly leave the drum 1 and enter the next process, thereby avoiding excessive tumbling and scattering of the tobacco and reducing tobacco breakage; at the same time, the tobacco scattered by the fourth shoveling plate 54 is blocked, thereby reducing the flying tobacco spillage when the tobacco collides with the inner wall when it is scattered and falls.

[0061] Furthermore, the included angles between the first copy board 51, the fifth copy board 55 and the center axis of the drum 1 are 30° to 60°, and when the copy board 5 is at the 9 o'clock position, the front of the copy board 5 is higher and the back of the copy board is lower.

[0062] Based on this, when the first and fifth scooping plates 51 and 55 rotate to the 9 o'clock position, all the tobacco thereon can slide from the feeding end to the discharging end through the upper surfaces of the scooping plates, thereby preventing the tobacco from being brought to too high a position by the tobacco scooping device and then falling, causing the tobacco to be broken and fly.

[0063] Furthermore, the included angle between the second copy board 52 and the center axis of the drum 1 is 3° to 10°, and when the copy board 5 is at the 9 o'clock position, the copy board 5 is higher at the front and lower at the back.

[0064] Based on this, as the drum 1 rotates, the tobacco shreds on the upper surface of the second scooping plate 52 are scattered and dropped in a certain order. That is, the tobacco shreds on the second scooping plate 52 are scattered from the front end first, and then to the rear end, and finally to the rear end, so that the tobacco shreds are scattered and mixed more continuously and evenly, and the tobacco shreds in contact with the atomized flavoring liquid are prevented from being too concentrated, thereby improving the uniformity of flavoring.

[0065] Another aspect of the present invention further comprises a spray device, comprising a nozzle 6 and a nozzle bracket 8 , wherein the nozzle 6 is disposed in the drum 1 .

[0066] Furthermore, the nozzle bracket 8 is fixed to the front end of the feed cover 2 and extends into the drum 1 from the front end.

[0067] Preferably, the spray cone angle of the nozzle 6 is 30° to 60°.

[0068] Furthermore, the spraying distance of the nozzle 6 is such that the tobacco shreds thrown and falling on the second shovel plate 52 are the fragrance liquid atomization area.

[0069] Furthermore, the spray angle, spray cone angle and spray distance of the nozzle 6 are adjustable.

[0070] Based on this, the angle between the nozzle and the central axis of the drum is increased as much as possible, the nozzle's spray partial pressure toward the rear end of the drum is reduced and the nozzle's spray partial pressure toward the tobacco is increased, the overflow of tobacco and atomized fragrance liquid is reduced, and the rate at which tobacco absorbs atomized fragrance liquid is increased; by increasing the nozzle's spray cone angle, the contact area between tobacco and atomized fragrance liquid is increased, thereby improving the uniformity of tobacco absorbing fragrance liquid.

[0071] Furthermore, a protective cover 7 is installed above the nozzle 6 .

[0072] Based on this, it is possible to prevent tobacco from hanging on the nozzle 6 and the nozzle bracket 8 during the scattering process, and to prevent a large amount of tobacco from hanging on the nozzle to affect the atomization effect of the fragrance liquid, and to prevent some tobacco from staying at the nozzle for too long to produce wet clumps of tobacco.

[0073] Preferably, the pressure of the fragrance liquid applied by the nozzle 6 is less than 1.0 bar, and the pressure of the ejected medium is between 0.5 bar and 2 bar.

[0074] Based on this, the atomized particle size of the scented liquid is made larger than 40 microns and smaller than 200 microns, which is conducive to the absorption of the scented liquid by the tobacco. At the same time, a smaller pressure is used to atomize and spray the scented liquid, so as to avoid the impact force of the scented liquid spraying process on the tobacco being too great, thereby causing turbulence in the drum environment and reducing the flying of tobacco and atomized scented liquid.

[0075] Furthermore, the angle formed by A3 and the center line of the discharging direction of the roller 1 is less than 90°.

[0076] Based on this, the spray pressure of the fragrance liquid pushes the tobacco in the discharge direction, preventing the tobacco and atomized fragrance liquid from flowing back and being adsorbed on the feed hood.

[0077] Preferably, the tobacco flavoring machine 2 is not provided with a dehumidification system.

[0078] The following will describe in detail the method of using the tobacco cutting device and the drum flavoring machine based on the above embodiment.

[0079] (1) Adjust the rotation speed of the drum 1 so that the material falls between 9 and 12 o'clock in the drum, that is, the tobacco starts to fall when the second pick 52 rotates to the 9 o'clock position, and the tobacco is completely scattered before it rotates to 12 o'clock;

[0080] (2) adjusting the center direction of the nozzle 6 so that it faces the middle area of ​​the axial direction of the second copying plate 52;

[0081] (3) The connecting line between the first copying plate 51 and the second copying plate 52 is A1, the connecting line between the second copying plate 52 and the third copying plate 53 is A2, the connecting line between the nozzle opening of the nozzle 6 and A1 is A3, and the connecting line between the nozzle opening of the nozzle 6 and A2 is A4. The pressure of the fragrance liquid and / or the pressure of the ejection medium is adjusted so that the spraying range of the nozzle 6 is within A3 and A4;

[0082] (4) According to the normal production flow rate, pressure and injection pressure of the aroma liquid, adjust the spray cone angle and spray direction of the nozzle so that the aroma liquid atomization area is within the loose area D of the tobacco shreds to prevent the aroma liquid from being sprayed onto the inner wall 11 of the drum 1.

[0083] Based on the above method, firstly, the tobacco shreds are scattered more loosely and the scattering area is increased; secondly, the fragrance liquid atomization area is overlapped with the material scattering loose area of ​​the second shoveling plate 52, so as to increase the mass transfer area between the tobacco shreds and the fragrance liquid, improve the absorption rate and uniformity of the fragrance liquid by the tobacco shreds, and reduce the environmental pollution and waste of raw materials caused by the overflow of the fragrance liquid; finally, the forward impact force of the fragrance liquid spraying is blocked by the tobacco shreds in the material blocking area of ​​the third shoveling plate 53, so as to avoid the waste of raw materials and the generation of wet smoke caused by the tobacco shreds and the atomized fragrance liquid being rushed to the discharge end and adsorbed on the inner wall of the equipment.

[0084] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
