Description

Technical Field

[0001] This utility model relates to the field of distillation pot technology, and in particular to a distillation pot. Background Technology

[0002] Malt whisky is typically obtained by distilling the fermented liquid in a copper still. Currently, the heat source for distillation is mostly steam, which heats the fermented liquid to raise its temperature, and then the alcohol and other components are separated based on their different boiling points.

[0003] Currently, the main methods of heating for distillation include gas-liquid heat transfer and open flame heating. Among these, open flame heating transfers the heat energy generated by combustion to the fermentation broth, thereby achieving the purpose of distillation.

[0004] In existing technologies, the bottom of distillation pots using open flame heating is often concave, with a lower center and higher edges. During open flame heating, substances in the fermentation broth tend to coke and adhere to the bottom of the distillation pot after prolonged burning. This coking is particularly severe in the center of the pot due to direct flame exposure. The concave design of the pot's bottom further exacerbates this problem, causing the coked material to concentrate in the center and become extremely difficult to remove after prolonged burning. Utility Model Content

[0005] The purpose of this invention is to provide a distillation pot with good distillation effect and less tendency to coke, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of this application, a distillation vessel is provided, comprising:

[0008] The pot body is hollow inside and has a accommodating space; the middle part of the bottom wall of the pot body extends upward beyond the edge;

[0009] A scraper is located within the accommodating space and is attached to the bottom wall of the pot body. The scraper is rotatably connected to the pot body to scrape off the adhering material on the bottom wall of the pot body and disperse it to the edge of the pot body.

[0010] In some embodiments, the bottom wall of the pot body gradually slopes downward from the center to the edge.

[0011] In some embodiments, the bottom wall of the pot is spherical or conical.

[0012] In some embodiments, the thickness of the bottom wall of the pot body is greater than or equal to 15 mm.

[0013] In some embodiments, the bottom wall of the pot body is provided with a discharge port.

[0014] In some embodiments, the scraping member includes at least two scraping units that are symmetrical about the center of the scraping member, and the shape of the scraping units is adapted to the shape of the bottom wall;

[0015] The bottom scraping unit is an arc shape with a concave surface facing a direction perpendicular to the radial direction of the pot body.

[0016] In some embodiments, the scraper is a chain.

[0017] In some embodiments, the distillation pot includes a drive assembly, which includes a motor and a rotating shaft. The motor is drivenly connected to the rotating shaft, and the rotating shaft is erected on the bottom wall of the pot body and rotatably connected to the pot body. The bottom of the rotating shaft is fixedly connected to the middle of the bottom scraper.

[0018] In some embodiments, the drive assembly includes a drive wheel and a rotating wheel. The drive wheel is sleeved on the output shaft of the motor and is fixedly connected to the output shaft of the motor. The rotating wheel is sleeved on the top of the rotating shaft and is fixedly connected to the rotating shaft. The drive wheel and the rotating wheel are meshed together.

[0019] In some embodiments, the distillation vessel further includes a support assembly, the support assembly including a support frame, the support frame being fixedly connected to the inner peripheral wall of the vessel body, and the support frame being sleeved on the upper part of the rotating shaft;

[0020] The scraping component includes at least two scraping units that are symmetrical about the center of the scraping component. The support assembly also includes at least two tie rods that are spaced apart circumferentially and evenly distributed around the outer periphery of the rotating shaft. The tie rods are arranged in a one-to-one correspondence with the scraping units, and the tie rods are connected between the rotating shaft and the outer ends of the scraping units.

[0021] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0022] In this invention, the distillation pot includes a pot body and a bottom scraper. The pot body is hollow and has an accommodating space. The middle part of the bottom wall of the pot body extends upward beyond the edge. The bottom scraper is located within the accommodating space and is attached to the bottom wall of the pot body. The bottom scraper is rotatably connected to the pot body to scrape off the adhering material on the bottom wall of the pot body and disperse it to the edge of the pot body.

[0023] In the aforementioned distillation pot, the rotating scraper agitates the fermentation broth, ensuring more even heating. Simultaneously, the scraper, attached to the pot body, scrapes away any adhering substances from the bottom wall during rotation. This effectively prevents the substances from scorching due to prolonged heating, maintaining heating efficiency and reducing the risk of carbonization, thus guaranteeing the distillation quality of the fermentation broth. Furthermore, the pot's bottom wall design, higher in the center and lower at the edges, disperses the scraped substances to the edges, preventing them from concentrating in the center and increasing the difficulty of removal after prolonged burning.

[0033] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0034] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] This application provides a distillation vessel, specifically used for distilling fermented liquid after fermentation to obtain distilled spirits (such as whiskey).

[0037] The still described in this application is a direct-fire heated still, meaning it uses an open flame to directly heat the bottom of the still. The heat generated by combustion is transferred to the fermentation liquid, thereby achieving distillation and producing distilled spirits such as whiskey with a distinctive flavor. Compared to gas-liquid heat transfer to heat the fermentation liquid, this application uses direct open-flame heating of the still, resulting in a higher temperature that allows the Maillard reaction to occur. The Maillard reaction imparts unique flavor and color to food, thus yielding distilled spirits such as whiskey with a distinctive flavor. Furthermore, the direct open-flame heating method reduces steam generation and transmission losses, thereby lowering production costs.

[0038] Specifically, the open flame heating point is mainly concentrated in the middle of the bottom of the distillation pot.

[0039] The open flame used in this application can be generated by burning natural gas.

[0040] The following detailed description, in conjunction with the accompanying drawings, describes specific embodiments of the distillation vessel of this application.

[0041] Figure 1 This is a schematic diagram of the distillation vessel in this embodiment. Figure 2 This is one of the cross-sectional views of the distillation vessel in this embodiment. Figure 3 This is another cross-sectional view of the distillation vessel in this embodiment.

[0042] refer to Figures 1-3The distillation vessel includes a vessel body 1 and a bottom scraper 2. The vessel body 1 is hollow and has a accommodating space. The bottom wall 11 of the vessel body 1 extends upwards beyond the edge. The bottom scraper 2 is located within the accommodating space and is attached to the bottom wall 11 of the vessel body 1. The bottom scraper 2 is rotatably connected to the vessel body 1 to scrape off any adhering material on the bottom wall 11 of the vessel body 1 and disperse it to the edge of the vessel body 1. In the distillation vessel described above, as the bottom scraper 2 rotates, it can stir the fermentation liquid, thereby making the fermentation liquid heat more evenly. At the same time, the bottom scraper 2 is attached to the vessel body 1, so that during the rotation, it can scrape off the adhering material on the bottom wall 11 of the vessel body 1, thereby effectively preventing the adhering material on the bottom wall 11 of the vessel body 1 from scorching due to prolonged heating, thus maintaining heating efficiency and reducing the risk of carbonization of the adhering material, effectively ensuring the distillation quality of the fermentation liquid. Furthermore, since the bottom wall 11 of the pot body 1 adopts a design that is high in the middle and low at the edges, as the scraper 2 rotates, the scraped-up deposits can be dispersed to the edges of the pot body 1 instead of being concentrated in the middle, so as to prevent the deposits from becoming more difficult to remove after prolonged burning.

[0043] The interior of the pot body 1 is hollow, forming a receiving space for containing the fermentation liquid after fermentation.

[0044] In this embodiment, the bottom wall 11 of the pot body 1 extends upward beyond the edge from the middle. That is, the bottom wall 11 of the pot body 1 in this embodiment has a shape that is high in the middle and low at the edge, which is aesthetically pleasing and highly recognizable. The open flame heating point is concentrated in the middle of the bottom wall 11 of the pot body 1.

[0045] Preferably, the bottom wall 11 of the pot body 1 slopes downward from the center to the edge.

[0046] In this embodiment, the bottom wall 11 of the pot body 1 is spherical or conical. That is, the vertical cross-section of the bottom wall 11 of the pot body 1 is arc-shaped or triangular.

[0047] In other embodiments, the height of the bottom wall 11 of the pot body 1 decreases in a stepped manner from the center to the edge.

[0048] In other embodiments, the bottom wall 11 of the pot body 1 may include a horizontal surface located in the middle and an inclined surface surrounding the outer periphery of the horizontal surface. That is, the vertical cross-section of the bottom wall 11 of the pot body 1 may also be trapezoidal.

[0049] In this embodiment, the thickness of the bottom wall 11 of the pot body 1 is greater than or equal to 15 mm. Because the pot body 1 in this embodiment is heated directly with an open flame during use, the fermentation liquid will undergo a Maillard reaction due to the high heating temperature. The Maillard reaction causes the portion of the fermentation liquid near the bottom of the pot body 1 to char and adhere to the bottom wall 11 of the pot body 1, requiring cleaning of the charred residue. However, during the cleaning process, some material on the bottom wall 11 of the pot body 1 is easily removed along with the residue, thus reducing the thickness of the bottom wall 11. Therefore, this embodiment increases the thickness of the bottom wall 11 of the pot body 1 to increase its service life.

[0050] In this embodiment, a discharge port 12 is provided at the edge of the bottom wall 11 of the pot body 1. That is, the discharge port 12 is located at the lowest point of the pot body 1 so that the lees remaining in the pot body 1 after distillation can be discharged outward.

[0051] In this embodiment, the pot body 1 is made of copper.

[0052] Preferably, a steam pipe 3 is connected to the top of the pot body 1 to vent the alcohol vapor generated inside the pot body 1 due to the heating of the fermentation liquid.

[0053] The steam pipe 3 includes a swan neck 31 and a Lynn arm 32.

[0054] The swan neck 31 extends vertically and connects to the top of the narrowed section of the pot body 1. The inner diameter of the swan neck 31 gradually decreases from bottom to top. When the alcohol vapor generated in the containment space evaporates and rises from the fermentation liquid, the lighter and more volatile part will more easily reach the top of the swan neck 31, while the heavier part will condense and flow back into the containment space along the inner wall of the swan neck 31. In other words, the swan neck 31 plays a role in vapor separation.

[0055] The top of the swan neck 31 curves upwards toward the edge of the pot body 1 to change the direction of the flow of wine vapor.

[0056] The end of the Lynn arm 32 furthest from the swan neck 31 is the outlet for alcohol vapor. Furthermore, the Lynn arm 32 is inclined downward relative to the horizontal plane to facilitate the flow of liquefied alcohol vapor within the Lynn arm 32 and to prevent backflow, allowing the alcohol vapor to pass through the Lynn arm 32 quickly.

[0057] refer to Figure 2 and Figure 3The scraper 2 is located within the accommodating space and is attached to the bottom wall 11 of the pot body 1. The scraper 2 is rotatably connected to the pot body 1. At this time, the scraper 2 can stir the fermentation liquid, thereby making the fermentation liquid more evenly heated. At the same time, the scraper 2 can scrape off the adhering substances on the bottom wall 11 of the pot body 1, thereby effectively preventing the adhering substances on the bottom wall 11 of the pot body 1 from scorching due to prolonged heating, thus maintaining heating efficiency and reducing the risk of carbonization of the adhering substances, effectively ensuring the distillation quality of the fermentation liquid. Furthermore, since the bottom wall 11 of the pot body 1 adopts a design that is higher in the middle and lower at the edges, as the scraper 2 rotates, the scraped adhering substances can be dispersed to the edge of the pot body 1.

[0058] Preferably, the center of the scraper 2 coincides with the center of the bottom wall 11 of the pot body 1. The center of the scraper 2 and the center of the bottom wall 11 of the pot body 1 are rotatably connected.

[0059] refer to Figure 3 In this embodiment, the scraping component 2 includes at least two scraping units 21, which are arranged symmetrically about the center of the scraping component 2.

[0060] The shape of the scraping unit 21 is adapted to the shape of the bottom wall 11 so as to scrape off the deposits attached to the bottom wall 11 of the pot body 1, effectively improving the cleaning speed of the bottom wall 11 of the pot body 1, and thus greatly improving the cleaning efficiency of the pot body 1.

[0061] The scraping unit 21 is arc-shaped, with the concave surface of the arc facing a direction perpendicular to the radial direction of the pot body 1.

[0062] In this embodiment, the bottom scraping component 2 includes two bottom scraping units 21, which are connected in an S-shape.

[0063] In this embodiment, the scraper 2 is a chain. Due to the inherent structural characteristics of the chain, which is formed by multiple interlocking rings and each ring can move relative to the other, the chain has a certain strength and a certain flexibility. When the chain length is appropriate, using the chain as the scraper 2 can utilize the flexibility of the chain to allow the scraper 2 to better adapt to the shape of the bottom wall 111 of the pot body 1, so that the scraper 2 fits snugly against the bottom wall 111 of the pot body 11.

[0064] In other embodiments, the scraper 2 can also be a plate structure.

[0065] refer to Figure 2 The distillation vessel includes a drive assembly for driving the bottom scraper 2 to rotate.

[0066] The drive assembly includes a motor 41 and a rotating shaft 42. The motor 41 is driven by the rotating shaft 42, which rotates the shaft. The rotating shaft 42 is erected on the bottom wall 11 of the pot body 1 and rotatably connected to the pot body 1. The bottom of the rotating shaft 42 is fixedly connected to the middle of the scraper 2. Rotation of the rotating shaft 42 drives the scraper 2 to rotate. The axis of the rotating shaft 42 coincides with the axis of the pot body 1.

[0067] The drive assembly includes a drive wheel 43 and a rotating wheel 44. The drive wheel 43 is sleeved on and fixedly connected to the output shaft of the motor 41, and rotates as the output shaft of the motor 41 rotates. The rotating wheel 44 is sleeved on the top of the rotating shaft 42 and fixedly connected to it. The drive wheel 43 and the rotating wheel 44 are meshed together, and the rotating wheel 44 rotates with the drive wheel 43, thereby driving the rotating shaft 42 to rotate.

[0068] In this embodiment, both the drive wheel 43 and the transmission wheel are gears. That is, the rotating shaft 42 and the motor 41 in this embodiment adopt gear transmission. This method can increase transmission efficiency, transmission accuracy and transmission stability, so as to ensure the smooth rotation of the rotating shaft 42, thereby ensuring the rotation efficiency and stability of the scraper 2.

[0069] In this embodiment, the distillation vessel also includes a support assembly.

[0070] The connecting assembly includes a support frame 51. The support frame 51 is fixedly connected to the inner peripheral wall of the pot body 1. The support frame 51 is sleeved on the upper part of the rotating shaft 42 and is rotatably connected to the rotating shaft 42 to strengthen the support of the rotating shaft 42 and improve the connection strength between the rotating shaft 42 and the pot body 1 as well as the stability of the rotating shaft 42.

[0071] Preferably, the support assembly further includes at least two tie rods 52 spaced circumferentially and evenly distributed around the outer periphery of the rotating shaft 42. The tie rods 52 are arranged one-to-one with the scraping unit 21, and the tie rods 52 are connected between the rotating shaft 42 and the outer end of the scraping member 2 to strengthen the connection between the scraping member 2 and the rotating shaft 42.

[0072] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0073] In the distillation vessel of this application, the bottom scraper stirs the fermentation broth as it rotates, resulting in more uniform heating. Simultaneously, the scraper, attached to the vessel body, scrapes off any adhering substances from the bottom wall during rotation. This effectively prevents the substances from scorching due to prolonged heating, maintaining heating efficiency and reducing the risk of carbonization, thus ensuring the distillation quality of the fermentation broth. Furthermore, the vessel's bottom wall design, higher in the center and lower at the edges, disperses the scraped substances to the edges as the scraper rotates, preventing them from concentrating in the center and increasing the difficulty of removal after prolonged burning.
