Description

Technical Field

[0001] This utility model relates to the field of flavor extraction technology, and in particular to a flavor extraction vessel for tobacco. Background Technology

[0002] The aromatic chemicals released from the combustion and decomposition of tobacco are the main source of the aroma and flavor of cigarettes. However, as an agricultural product, the quality of tobacco is often affected by cultivation conditions and subsequent processing, resulting in fluctuations in product quality. To meet the quality requirements of tobacco product processing and to harmonize the impurities in tobacco itself, flavorings and fragrances are usually added to compensate for any deficiencies in the tobacco's natural aroma, thus harmonizing and improving the aroma and flavor. Tobacco flavorings and fragrances play a crucial role in improving the taste of cigarettes, compensating for and enhancing their aroma, and highlighting the brand style. It can be said that "aroma is the soul of cigarettes," and the extraction technology of tobacco flavorings and fragrances is extremely important in the cigarette industry as a vital aspect of tobacco product processing.

[0003] The equipment commonly used for extracting tobacco flavorings varies depending on the extraction method, mainly including distillation equipment, extraction equipment, and filtration equipment. Solvent extraction equipment is quite common, typically consisting of an extraction vessel, a stirrer, and a separator. Tobacco raw materials and extraction solvent are added to the extraction vessel, and the mixture is stirred to ensure the flavoring components are fully dissolved in the solvent. The extract and residue are then separated by the separator. During the stirring process, workers continuously add auxiliary materials to the vessel through a feeding pipe at the top. Typically, the feeding pipe is located on one side of the stirrer inside the vessel, offset from the stirrer. Therefore, if too much auxiliary material is added at once, it will concentrate in one area, resulting in excessively high concentrations and over-reaction between the liquid and the auxiliary material. Other areas, due to insufficient auxiliary material, will not have adequate contact, leading to uneven extraction of flavoring components from the raw material, which requires optimization.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a tobacco flavor extraction vessel, including a stirring vessel 1 and a vessel cover 2. The stirring vessel 1 is provided with a discharge port 14 at its lower end, and the vessel cover 2 is provided with a mechanical box 3 and a first filling pipe 6 at its upper end. The vessel cover 2 is provided with a stirrer at its lower end, and the mechanical box 3 is provided with a forward and reverse rotation device for controlling the rotation of the stirrer.

[0024] The slurry is injected into the mixing vessel 1 through the first injection pipe 6 for extraction. The stirrer is rotated by the forward and reverse rotation device. The stirrer stirs the slurry in the mixing vessel 1 during rotation, so that the slurry and the fragrance are mixed.

[0025] Specifically, the agitator includes a stirring cylinder 9 and a hollow rotating shaft 10. The stirring cylinder 9 is sleeved on the outside of the hollow rotating shaft 10 and is rotatably connected to the hollow rotating shaft 10. The upper end of the stirring cylinder 9 passes through the lid 2 and is rotatably connected to the lid 2. The upper end of the hollow rotating shaft 10 is rotatably connected to the second filling pipe 4 located on the upper end of the machine box 3.

[0026] The lower end of the hollow rotating shaft 10 is fixedly connected to the stirring blades B12 arranged around the stirring drum 9. The stirring blades B12 are provided with multiple one-way liquid outlets 13 on the side facing the stirring drum 9. The second filling pipe 4 is connected to the stirring blades B12 and the one-way liquid outlets 13 through the hollow rotating shaft 10.

[0027] The forward and reverse rotation device controls the rotation of the stirring drum 9 and the hollow rotating shaft 10. During the rotation, the stirring drum 9 and the hollow rotating shaft 10 can simultaneously agitate the slurry in the outer and central areas of the vessel cavity. During the agitation process, the solution additives can be injected into the hollow rotating shaft 10 through the second injection pipe 4 on the mechanical box 3, and then thrown into the stirred vessel 1 through the rotating stirring blades B12. The one-way outlet 13 is directly facing the stirring drum 9. The solution additives injected into the stirred vessel 1 can be immediately dispersed by the stirring drum 9 and fully mixed with the nearby slurry, further improving the fusion extraction efficiency.

[0028] One-way outlet 13 has a one-way flow function, allowing liquid to flow out but not in. For its specific structure, please refer to [reference needed]. Figure 4 I won't go into too much detail.

[0029] It is worth explaining in detail that at least two stirring blades A11 are provided on the outer side of the mixing drum 9. The stirring blades A11 are positioned between the stirring blade B12 and the mixing drum 9 and are offset from the stirring blade B12. The stirring blades A11 are U-shaped, and both the upper and lower ends of the stirring blades A11 are fixedly connected to the outer wall of the mixing drum 9. When the mixing drum 9 rotates, it drives the stirring blades A11 to rotate. The rotation of the stirring blades A11 agitates the slurry around the mixing drum 9, accelerating the mixing between the slurry and the auxiliary materials.

[0030] Regarding the forward and reverse rotation device:

[0031] The forward and reverse rotation device includes a forward rotation driver and a reverse rotation driver. The forward rotation driver is located inside the mechanical housing 3 and is used to control the rotation of the stirring drum 9. The reverse rotation driver is located inside the mechanical housing 3 and is used to control the rotation of the hollow rotating shaft 10. The stirring drum 9 and the hollow rotating shaft 10 rotate in opposite directions.

[0032] The mixing drum 9 and the mixing blade B12 are controlled to rotate by a forward and reverse rotation device. Since the mixing drum 9 and the mixing blade B12 rotate in opposite directions, a shear force is generated between them when they rotate, which can quickly disperse the droplets injected by the one-way liquid outlet 13 and further accelerate the mixing of the slurry.

[0033] Specifically, the forward drive includes a first bevel gear 15, a second bevel gear 16, and a motor 17. The first bevel gear 15 is fixedly mounted on the upper end of the stirring drum 9, and the second bevel gear 16 is rotatably mounted inside the machine box 3. The first bevel gear 15 meshes with the second bevel gear 16. The motor 17 is fixedly mounted on the outer side of the machine box 3, and the output end of the motor 17 is fixedly connected to the second bevel gear 16.

[0034] Motor 17 controls the second bevel gear 16 to rotate. As the second bevel gear 16 rotates, it meshes with the first bevel gear 15, causing the first bevel gear 15 to rotate. Since the first bevel gear 15 is fixed to the stirring drum 9, when the first bevel gear 15 rotates, the stirring drum 9 will also rotate. The stirring drum 9 completes the stirring of the slurry in the central area of ​​the stirring vessel 1 while rotating.

[0035] Specifically, the reverse drive includes a third bevel gear 18, which is positioned above the first bevel gear 15. The third bevel gear 18 is sleeved on the outside of the hollow shaft 10 and fixedly connected to the hollow shaft 10. The third bevel gear 18 and the first bevel gear 15 are respectively located on both sides of the second bevel gear 16, and the third bevel gear 18 meshes with the second bevel gear 16.

[0036] Motor 17 drives the second bevel gear 16 to rotate. During the rotation of the second bevel gear 16, it simultaneously meshes with the third bevel gear 18 and the first bevel gear 15. Since the second bevel gear 16 is located between the third bevel gear 18 and the first bevel gear 15, when the second bevel gear 16 drives the first bevel gear 15 to rotate in the forward direction, the third bevel gear 18, which meshes with the second bevel gear 16, will drive the hollow rotating shaft 10 to rotate in the opposite direction. The hollow rotating shaft 10 completes the stirring of the slurry in the edge area of ​​the mixing vessel 1 during rotation.

[0037] It is worth explaining in detail that the second filling tube 4 is fixedly installed at the upper end of the mechanical box 3. The upper end of the second filling tube 4 is provided with a liquid injection conduit 5, and the lower end of the second filling tube 4 is rotatably connected to the hollow rotating shaft 10. The end of the liquid injection conduit 5 away from the second filling tube 4 is connected to a pump. The pump injects the excipient into the liquid injection conduit 5, and then injects it into the hollow rotating shaft 10 through the second filling tube 4. The second filling tube 4 and the hollow rotating shaft 10 are connected by a slip ring. The slip ring can pass the excipient solution entering the second filling tube 4 into the hollow rotating shaft 10 without affecting the rotation of the hollow rotating shaft 10.

[0038] It is worth explaining in detail that a steam jacket 7 is provided inside the stirred tank 1, and the steam jacket 7 is connected to the steam injection pipe 8 located on the outside of the stirred tank 1. The steam injection pipe 8 includes an injection pipe and an outlet pipe. The injection pipe is located at the top of the stirred tank 1, and the outlet pipe is located at the bottom of the stirred tank 1. High-temperature steam is introduced into the steam jacket 7 through the injection pipe and then discharged to the outside through the outlet pipe. High-temperature steam is used to heat and keep the slurry inside the stirred tank 1 from the inside.

[0039] How this application works:

[0040] The slurry is injected into the stirred tank 1 for extraction through the first injection pipe 6. The agitator is rotated by a forward and reverse rotation device. The stirring drum 9 and the hollow rotating shaft 10 can simultaneously agitate the slurry in the outer and central areas of the tank cavity, accelerating the mixing of the slurry and fragrance. During the agitation process, the solution excipients can be injected into the hollow rotating shaft 10 through the second injection pipe 4 on the mechanical box 3, and then thrown into the stirred tank 1 by the rotating stirring blades B12. The one-way outlet 13 is directly opposite the stirring drum 9. The solution excipients injected into the stirred tank 1 can be immediately dispersed by the stirring drum 9 and fully mixed with the surrounding slurry, further improving the fusion extraction efficiency.
