Description

Technical Field

[0001] This invention relates to the field of brewing technology, and in particular to a wine distillation tower and a wine distillation system. Background Technology

[0002] The core quality of high-purity distilled spirits depends on the purity of the alcohol and the types and contents of flavor compounds such as aldehydes, esters, and alcohols. Traditional high-purity distilled spirits are generally produced using a multi-tower distillation process, which separates alcohol and flavor compounds through multiple heating and distillation.

[0003] A multi-tower distillation process may include at least one distillation column. The distillation column includes a column body, a reboiler assembly, a condenser assembly, and multiple trays. The column body extends vertically. A vertically extending distillation space is formed within the column body. The reboiler assembly is located at the bottom of the column body to boil the liquid within the distillation space, allowing vapor to flow from bottom to top. The condenser assembly is located at the top of the column body to condense the vapor at the top of the column, allowing the condensate to flow downwards from the top of the distillation space. Multiple trays are spaced vertically within the distillation space, and the trays temporarily hold a portion of the liquid. Multiple spaced-apart riser channels are provided on the trays to facilitate countercurrent gas-liquid contact and mass and heat transfer between the high-pressure vapor below the trays and the liquid above the trays.

[0004] In related technologies, different wines contain varying alcohol concentrations, types and amounts of flavor compounds. Current distillation columns cannot adjust the mass and heat transfer range between vapor and liquid, making it impossible to adjust the alcohol concentration and flavor compounds in real time according to the type of wine and desired taste. Summary of the Invention

[0008] In this embodiment, a first containment weir is provided on the outer ring plate. The first containment weir extends in a ring shape along the inner circumference of the outer ring plate. The first containment weir, the outer ring plate, and the inner peripheral wall of the tower body enclose and form a first receiving groove. The first receiving groove is used to receive the liquid output from the first tower plate on the upper side.

[0009] In this embodiment, a second containment weir is provided on the central plate, and the second containment weir is arranged in a ring around the outer periphery of the central plate; the movable leaf, the second containment weir and the first containment weir can be enclosed to form a second receiving groove, which is used to receive liquid overflowing from the adjacent first receiving groove.

[0010] In this embodiment, the height of the top of the second retaining wall is lower than the height of the top of the first retaining wall in the vertical direction.

[0011] In this embodiment, a receiving groove is recessed on the outer periphery of the outer ring plate, and the receiving groove is arranged in a ring along the circumference of the outer ring plate; the first tray includes a first plate body and a first liquid descending member, the first plate body extends horizontally to receive liquid on its upper side to form a liquid layer; the upper end of the first liquid descending member communicates with the upper side of the first plate body, and the lower end of the first liquid descending member is located on the upper side of the receiving groove, so that the first liquid descending member can transport the liquid on the upper side of the first plate body into the receiving groove.

[0012] In this embodiment, the outer ring plate is provided with a plurality of float valves on the inner side of the receiving groove; the plurality of float valves include a plurality of T-shaped float valves, a plurality of first circular float valves and a plurality of strip float valves arranged at intervals; in the direction away from the center of the outer ring plate, the strip float valves, the first circular float valves and the T-shaped float valves are arranged in a ring along their own circumference in sequence on the outer ring plate; in the direction away from the center of the central plate, a plurality of second circular float valves are provided on the central plate, and a plurality of third circular float valves are provided on the movable leaf.

[0013] In this embodiment, a plurality of second trays are spaced apart along the vertical direction inside the column body; the number of T-type float valves and strip float valves in the second trays in the upper part of the distillation space is less than the number of T-type float valves and strip float valves in the second trays in the lower part of the distillation space; the number of first circular float valves in the second trays in the upper part of the distillation space is greater than the number of first circular float valves in the second trays in the lower part of the distillation space.

[0014] In this embodiment, the liquor distillation column further includes multiple rotating shafts and a driving component. The rotating shafts are located on the lower side of the central plate. The multiple rotating shafts are respectively arranged around the periphery of the central plate corresponding to multiple movable blades. The rotation axis of the rotating shaft passes through the center of the central plate and extends along the interval between the outer ring plate where the corresponding movable blade is located and the central plate. The two ends of the rotating shaft are rotatably connected to the central plate and the outer ring plate, respectively.

[0017] As can be seen from the above technical solution, this application has at least the following advantages and positive effects: In this application, when the distillation column distills dealdehyde-removed spirits, the liquid flows from top to bottom within the distillation space. During this flow, liquid layers form on both the first and second trays. The reboiling assembly heats the liquid at the bottom of the distillation space to generate steam. As the steam flows from bottom to top, it enters the liquid layers on both the first and second trays, allowing for sufficient contact between the steam and liquid for mass and heat transfer. When the distillation column distills spirits of different varieties and flavor compounds, operators can adjust the rotation angle of multiple movable blades to regulate the opening of the flow channels between them, allowing steam from the lower side of the second tray to enter the liquid layer on the upper side of the second tray through the flow channels. Mass and heat transfer between the steam and liquid regulates the condensed components in the steam and the evaporated components in the liquid layer, thereby adjusting the alcohol concentration and flavor compounds in the final distillate output from the condensation assembly and improving the production efficiency of the spirits.

It should be understood that this application can have various variations in different embodiments, all of which do not depart from the scope of this application, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this application.

[0024] In related technologies, the production process of liquor includes raw material pretreatment, fermentation, crude distillation, and rectification. Raw material pretreatment involves cleaning, cutting, and saccharifying the raw materials to form saccharified mash. After fermentation, the saccharified mash is used to extract the fermentation liquid. This fermentation liquid undergoes extraction, degassing, and rectification to produce a distillate. The distillate then undergoes blending, dilution, and other post-treatments to form the finished liquor.

[0025] Figure 1 This is a schematic diagram of the structure of the wine distillation system of the present invention.

[0026] See Figure 1 This application provides an alcohol distillation column capable of distilling dealdehyde-removed alcohol to form a distillate. The distillate is then subjected to washing with water and other environmental processes to form crude alcohol.

[0027] See Figure 1 For ease of description and understanding, the vertical direction of the alcohol distillation column will be referred to as the vertical direction in the following text, and the direction perpendicular to the vertical direction will be referred to as the horizontal direction in the following text.

[0028] Figure 2 This is a schematic diagram of the structure of the wine distillation tower of the present invention. Figure 3 This is the present invention. Figure 2 Sectional view at point AA.

[0029] See Figure 2 and Figure 3In this embodiment, the liquor distillation column 10 includes a column body 210, a reboiling assembly 220, a condensing assembly 230, a first tray 250, and a second tray 260. The column body 210 extends vertically. A vertically extending distillation space 211 is formed within the column body 210. An inlet for dealdehyde-treated liquor is provided on the column body 210. The reboiling assembly 220 is located at the bottom of the column body 210. The reboiling assembly 220 is used to boil the liquid at the bottom of the distillation space 211 and generate steam. The condensing assembly 230 is located at the top of the column body 210. The condensing assembly 230 is used to condense the steam at the top of the distillation space 211 into condensate, and is configured to allow the condensate to be transported into the distillation space 211. The condensing assembly 230 is also configured to allow the condensate to be discharged to downstream devices for further processing of the distillate to form crude alcohol. The first tray 250 is located within the distillation space 211. The first tray 250 is used to receive the liquid on its upper side and can collect the liquid on the first tray 250 and convey it downwards. The second tray 260 is disposed in the rectification space 211. The second tray 260 is located below the first tray 250. The second tray 260 includes a central plate 261, an outer ring plate 262 spaced around the outer periphery of the central plate 261, and a plurality of movable blades 263. The outer ring plate 262 extends horizontally, and its outer periphery is sealed to the inner peripheral wall of the column body 210 to receive the liquid conveyed by the first tray 250 to form a liquid layer. The plurality of movable blades 263 are located between the outer ring plate 262 and the central plate 261, and are arranged sequentially around the circumference of the central plate 261. The movable blades 263 are rotatably connected to the outer ring plate 262 and the central plate 261, and the rotation axis of the movable blades 263 extends along the spacing direction between the outer ring plate 262 and the central plate 261. Among them, the movable blades 263 can rotate to seal and fit any two adjacent movable blades 263 together, and multiple movable blades 263 are sealed and fitted with the outer ring plate 262 and the center plate 261. Multiple movable blades 263 can also rotate to form a flow channel connecting the upper and lower sides of the second tray 260 by creating a gap between any two adjacent movable blades 263.

[0030] When the alcohol distillation column 10 distills dealdehyde-removed alcohol, the liquid flows from top to bottom within the distillation space 211. During this flow, liquid layers form on both the first tray 250 and the second tray 260. After passing through the first tray 250 and the second tray 260, the liquid gathers at the bottom of the distillation space 211. The reboiling assembly 220 heats the liquid at the bottom of the distillation space 211 to generate vapor. As the vapor flows from bottom to top, it enters the liquid layers on the first tray 250 and the second tray 260, allowing for sufficient contact between the vapor and liquid for mass and heat transfer. This causes some substances in the vapor to condense and enter the liquid layer, while some substances in the liquid layer evaporate into vapor and flow upward. After rising to the top of the distillation space 211, the vapor condenses under the action of the condensation assembly 230 to form condensate. The condensate formed by the condenser assembly 230 can be returned to the rectification space 211, allowing the condensate to flow again from top to bottom within the rectification space 211. This enables multiple rectifications of the dealdehyde-treated wine, improving the rectification efficiency and quality. Furthermore, the condenser assembly 230 can also output a portion of the condensate to form a rectification liquid.

[0031] When the distillation column 10 distills different varieties and flavor compounds of liquor, the operator can adjust the rotation angle of multiple movable blades 263 as needed to regulate the opening of the flow channels between them. This allows the vapor on the lower side of the second tray 260 to enter the liquid layer on the upper side of the second tray 260 through the flow channels. Mass and heat transfer occur between the vapor and the liquid layer to regulate the condensed components in the vapor and the evaporated components in the liquid layer. This, in turn, regulates the alcohol concentration and flavor compounds in the distillate output from the final condenser 230, improving the liquor production efficiency.

[0032] Furthermore, when the second tray 260 of the liquor distillation column 10 is overloaded with a large amount of liquid, causing the column to flood, the operator can increase the opening of the flow channel by rotating the movable blade 263. This allows the liquid on the second tray 260 to be quickly fed into the lower side of the second tray 260 through the flow channel, preventing the steam from switching from foam contact mass transfer to bubbling mass transfer due to the thick liquid layer on the second tray 260. This also prevents long-chain fatty acid esters, fusel oils, and organic acids in the liquid layer from volatilizing and mixing into the steam, thus preventing the flavor of the final liquor from deteriorating and improving the purity of the distillate.

[0033] When the liquid level on the second tray 260 of the liquor distillation column 10 is low, the liquid layer on the upper side of the second tray 260 is thin, and the vapor load on the lower side of the second tray 260 is too high. This can easily cause the vapor to tear the liquid layer, resulting in localized dryness on the second tray 260 and near-ineffective vapor-liquid contact. In this situation, the operator can rotate the movable blade 263 to reduce or close the flow channel, allowing the vapor to pass through the tray and contact the liquid layer on the upper side of the second tray 260 for mass transfer. This prevents the second tray from drying out and ensures that aldehydes and fusel oils in the vapor are not condensed and absorbed by the liquid layer, thus reducing the pungent flavor of the distillate.

[0034] In related technologies, flooding refers to an overload of liquid on the trays, obstructing vapor flow below and drastically extending the liquid residence time. Flooding results in large amounts of long-chain fatty acid esters, fusel oils, and organic acids remaining in the vapor, leading to excessive levels of cold components and ultimately a bitter and cloudy final product.

[0035] In related technologies, "dry plate" refers to a situation where the steam load on the lower side of the tray is too high, the liquid load on the tray is extremely low, the opening of the flow channel is too small, and the steam flow cross-section is insufficient. The high-speed steam output from the flow channel tears and breaks down the liquid layer on the upper side of the second tray 260, preventing the liquid layer from spreading evenly. This results in localized dryness of the tray 263, almost eliminating gas-liquid contact and mass transfer, and rendering the second tray 260 ineffective for liquid-phase washing and extraction. Dry plate causes aldehydes and light fusel oils, due to their extremely low boiling points or high volatility, to be unable to condense and throttle, remaining entirely in the steam and ultimately entering the finished wine. Furthermore, a large amount of mid-boiling aromatic esters, such as ethyl acetate and ethyl lactate, are stripped away by the steam flow and enter the finished wine, while high-boiling heavy fusel oils and fatty acids are entrained and drawn upwards by the deviated steam into the finished wine. Ultimately, this results in a pungent taste and acrid odor in the finished wine.

[0036] When a portion of the second tray 260 becomes dry, the opening of the hinge 263 is finely adjusted to regulate the steam flow area. This ensures that steam is evenly and stably introduced into the liquid layer through the flow channel, guaranteeing a uniform liquid surface without dry areas on the upper side of the hinge 263 and restoring gas-liquid foam contact mass transfer within the liquid layer. Once gas-liquid foam contact mass transfer is restored, it can retain light aldehydes and low-carbon fusel alcohols, reducing the pungent and harsh taste of the finished liquor; it can also retain medium-chain alcohols and esters, restoring the grain aroma and mellow sweetness of the liquor; and it can prevent heavy components from rising, eliminating oily, bitter, and off-flavors. Simultaneously, the opening adjustment of the hinge 263 can also finely adjust the reflux ratio, assisting in the extraction of head impurities from the heads of the liquor and the discharge of tail impurities from the tail, precisely separating flavor impurities through grading.

[0037] See Figure 2 and Figure 3In this embodiment, the column body 210 may include a cylindrical body and end caps disposed at both ends of the cylindrical body. The cylindrical body extends vertically. The two end caps are respectively sealed and connected to the upper and lower ends of the cylindrical body, so that the two end caps and the cylindrical body enclose a sealed distillation space 211.

[0038] In some embodiments, the upper part of the cylinder may be provided with a feed inlet to allow the dealdehyde-removed wine to enter the distillation space.

[0039] In some embodiments, the cylinder can be cylindrical to facilitate uniform distribution of gas and liquid within the cylinder during flow, and to ensure that there are no dead zones or stagnant areas in the liquid layer on the tray; at the same time, the cylinder can also improve the manufacturing efficiency of the tower body 210 and ensure the structural strength of the tower body 210.

[0040] See Figure 2 In this embodiment, the reboiler assembly 220 is disposed on the outside of the column body 210 and is connected to the bottom of the distillation space 211 for boiling the liquid at the bottom of the distillation space 211.

[0041] The reboiling assembly 220 may include a first inlet pipe 221, a reboiler 222, and a first outlet pipe 223. The inlet end of the first inlet pipe 221 is connected to the rectification space 211, and the outlet end of the first inlet pipe 221 is connected to the inlet end of the reboiler 222. The reboiler 222 is used to heat and boil the liquid input through the first inlet pipe 221 to form a gas-liquid mixture. The inlet end of the first outlet pipe 223 is connected to the reboiler 222, and the outlet end of the first outlet pipe 223 is connected to the rectification space 211, for returning the gas-liquid mixture heated by the reboiler 222 to the rectification space 211, thereby causing the vapor in the gas-liquid mixture returning to the rectification space 211 to flow from bottom to top.

[0042] In some embodiments, the input end of the first input pipe 221 is connected to the bottom of the distillation space 211. The output end of the first output pipe 223 is located above the input end of the first input pipe 221, so that the liquid at the bottom of the distillation space 211 is circulated and heated under the action of the first input pipe 221, the reboiler 222 and the first output pipe 223, thereby improving the heating efficiency of the liquid in the distillation space 211.

[0043] In some embodiments, the reboiler 222 can be a thermosiphon reboiler 222, a kettle reboiler 222, etc., to absorb the liquid in the distillation space 211 and heat it.

[0044] In some embodiments, the reboiler assembly 220 may include a circulation pump (not shown). The circulation pump is disposed on the first inlet pipe 221 to pump liquid in the distillation space 211 into the reboiler 222 to assist in the circulation and heating of the liquid.

[0045] In other embodiments, it may be unnecessary to set up the first input pipe 221 and the first output pipe 223. The reboiler 222 may be set at the bottom of the distillation space 211 to directly heat and boil the liquid at the bottom of the distillation space 211.

[0046] See Figure 2 In this embodiment, the condenser assembly 230 is disposed on the outside of the column body 210 and communicates with the top of the distillation space 211 to condense the vapor at the top of the distillation space 211.

[0047] The condenser assembly 230 may include a second inlet pipe 231, a condenser 232, and a second outlet pipe 233. The inlet end of the second inlet pipe 231 is connected to the rectification space 211, and the outlet end of the second inlet pipe 231 is connected to the inlet end of the condenser 232. The condenser 232 is used to condense the vapor input through the second inlet pipe 231 to form condensate. The inlet end of the second outlet pipe 233 is connected to the condenser 232, and the outlet end of the second outlet pipe 233 is connected to the rectification space 211, so as to return the condensate condensed by the condenser 232 to the rectification space 211, thereby allowing the condensate flowing back into the rectification space 211 to flow from top to bottom. The condenser assembly 230 and the reboiling assembly 220 can cooperate to achieve circulating rectification of the liquid in the rectification space 211, improving rectification efficiency and ensuring the rectification quality of the final output distillate.

[0048] In some embodiments, the input end of the second input pipe 231 can be connected to the top of the distillation space 211 to receive vapor from the top of the distillation space 211. The output end of the second output pipe 233 can be located on the upper side of the first tray 250 and connected to the peripheral wall of the column body 210, so that the output condensate can flow downward along the inner peripheral wall of the column body 210 to ensure the stability of the liquid layer on the upper side of the first tray 250.

[0049] See Figure 2 In this embodiment, the wine distillation column 10 further includes a communication component. The communication component may also include a first discharge pipe 241 and a second discharge pipe 242. The input end of the first discharge pipe 241 is connected to the output end of the reboiler 222 or the output end of the circulating pump, and the output end of the first discharge pipe 241 is connected to the outside environment to discharge the liquid at the bottom of the distillation space 211 to the outside environment, thereby facilitating the cleaning of the wine distillation column 10. The input end of the second discharge pipe 242 is connected to the output end of the condenser 232 or the second output pipe 233, and the output end of the second discharge pipe 242 is connected to a downstream device, thereby outputting the distillate to the downstream device for processing, facilitating the final formation of the finished wine product from the distillate.

[0050] See Figure 2In this embodiment, the communication component may include a reflux pipe 243. The input end of the reflux pipe 243 is connected to the output end of the reboiler 222, and the output end of the reflux pipe 243 is connected to the top of the distillation space 211. This is used to transport the liquid at the bottom of the distillation space 211 to the top of the distillation space 211, so that the liquid flows from top to bottom from the top of the distillation space 211, which helps to realize multiple distillations of the distillate, avoids the alcohol distillation column 10 from drying out during the distillation process, ensures the quality of the circulating distillation of the alcohol distillation column 10, and ensures the safety and reliability of the alcohol distillation column 10 in use.

[0051] In some embodiments, the first input pipe 221, the first output pipe 223, the second input pipe 231, the second output pipe 233, the first discharge pipe 241, the second discharge pipe 242, and the return pipe 243 may be equipped with one-way shut-off valves, flow control valves, or on / off valves to facilitate the control of the wine distillation column 10.

[0052] In this embodiment, the wine distillation column 10 includes multiple trays spaced vertically. The multiple trays may include a first tray 250. The first tray 250 includes a first plate body 251 and a first downcomer 252. The first plate body 251 extends horizontally to seal against the inner peripheral wall of the column body 210. The first plate body 251 receives liquid on its upper side, thereby forming a liquid layer on the first plate body 251. The first downcomer 252 is located on the periphery of the first plate body 251. The first downcomer 252 extends vertically, with its upper end communicating with the first plate body 251 and its lower end corresponding to other trays. It guides and outputs the liquid on its own first plate body 251 to the lower tray, ensuring a smooth liquid layer on each tray and preventing liquid layer deviation and localized foam entrainment of dry plates due to liquid falling impact. This improves the gas-liquid mass transfer efficiency and operational stability of the wine distillation column 10.

[0053] See Figure 2 In this embodiment, the first plate 251 extends horizontally to be sealed to the inner peripheral wall of the tower body 210, and a notch 2511 is provided on one side of the first plate 251. The first liquid descending member 252 is sealed to the first plate 251. The upper end of the first liquid descending member 252 extends upward beyond the first plate 251. The first liquid descending member 252 extends horizontally along the notch 2511 of the first plate 251 and is sealed to the inner wall of the tower body 210, so that the first liquid descending member 252, the first plate 251, and the inner peripheral wall of the tower body 210 enclose a sealed working groove 253. The working groove 253 is used to contain liquid and form a liquid layer, thereby facilitating gas-liquid mass transfer.

[0054] In some embodiments, the first liquid-receiving element 252 may be a plate-like structure for receiving and guiding liquid flow.

[0055] See Figure 2 In this embodiment, the first plate 251 has multiple spaced-apart rising gas channels. The rising gas channels are used to allow steam on the lower side of the first plate 251 to flow upward and enter the liquid layer, thereby realizing mass and heat transfer between steam and liquid.

[0056] In some embodiments, the gas rising channel can be a connecting hole opened on the first plate 251, so that steam can be input into the liquid layer under pressure, and the steam can support the liquid at the connecting hole, preventing the liquid from leaking to the lower side of the first plate 251 through the connecting hole.

[0057] In some embodiments, the air riser channel can be a float valve disposed on the first plate 251. The specific structure of the float valve is not claimed in this application and can be selected based on existing technology. In other embodiments, the float valve can be a circular float valve or a strip float valve. The float valve can also be a T-type float valve, a conical float valve, or a toothed float valve, etc.

[0058] In some embodiments, the gas riser channel may also be a bubble cover, a fixed valve, etc. The bubble cover and the fixed valve may adopt conventional structures in the art, and will not be described in detail here.

[0059] See Figure 2 In this embodiment, a buffer groove 254 is recessed on the side of the first plate 251 away from the first liquid descending member 252 in the horizontal direction. The buffer groove 254 is used to receive and contain liquid to reduce the fluctuations caused by the liquid impacting the first plate 251 when flowing from top to bottom, thereby improving the gas-liquid mass transfer efficiency.

[0060] See Figure 2 In this embodiment, there can be multiple first trays 250. The multiple first trays 250 are arranged at intervals in the vertical direction to realize multiple mass transfers between vapor and liquid, thereby improving the distillation efficiency of dealdehyde-removed wine.

[0061] In some embodiments, when any two first trays 250 are arranged adjacent to each other, the first liquid descending member 252 of the upper first tray 250 is arranged corresponding to the buffer groove 254 of the lower first tray 250, and the lower end of the upper first liquid descending member 252 extends downward into the buffer groove 254 of the lower side to reduce the fluctuations caused by liquid impact, ensure the smooth flow of liquid in the working tank 253, and ensure gas-liquid mass transfer efficiency and operational stability.

[0062] See Figure 2 and Figure 3 In this embodiment, the multiple trays may include a second tray 260. The second tray 260 is disposed below the first tray 250 to receive liquid output from the upper tray. A liquid layer is formed on the second tray 260 to achieve gas-liquid mass transfer and improve the distillation efficiency and quality of the wine distillation column 10.

[0063] The second tray 260 may include a center plate 261, an outer ring plate 262, multiple impellers 263, and multiple air risers. The center plate 261 extends horizontally. The outer ring plate 262 is arranged around the outside of the center plate 261 and spaced apart from it. Multiple impellers 263 are arranged sequentially around the circumference of the center plate 261 and are rotatably connected to the center plate 261 and the outer ring plate 262. The rotation axis of the impellers 263 extends along the spacing between the outer ring plate 262 and the center plate 261. The impellers 263 can rotate to seal against any two adjacent impellers 263, and the multiple impellers 263 are sealed against the outer ring plate 262 and the center plate 261. The multiple impellers 263 can also rotate to create a gap between any two adjacent impellers 263, thereby forming a flow channel connecting the upper and lower sides of the second tray 260 between any two adjacent impellers 263. Multiple rising gas channels are spaced apart on the center plate 261, outer ring plate 262 and movable blade 263 so that the steam on the lower side of the second tray 260 can pass upward through the rising gas channels through the second tray 260.

[0064] When a liquid layer forms on the second tray 260, multiple movable blades 263 can rotate to seal and fit between any two adjacent movable blades 263, and multiple movable blades 263 are sealed and fitted with the outer ring plate 262 and the center plate 261, so that the vapor on the lower side of the second tray 260 can only enter the liquid layer on the upper side of the second tray 260 through the rising gas channel on it, thereby realizing gas-liquid mass transfer.

[0065] When staff produce liquors with different alcohol concentrations and flavors, they can rotate multiple movable leaves 263 to open the flow channels between them and control the opening of the flow channels. This allows steam to enter the liquid layer on the upper side of the second tray 260 through the flow channels, achieving gas-liquid mass and heat transfer. This allows for real-time adjustment of the alcohol concentration and flavor components of the output distillate, adjusting the alcohol concentration and taste of the finished liquor, improving the production efficiency of the finished liquor, and increasing the applicability and versatility of the liquor distillation tower 10.

[0066] Meanwhile, when the alcohol distillation tower 10 is flooded or dried out during operation, the staff can adjust the opening of the movable leaf 263 to prevent the alcohol distillation tower from flooding or drying out, thus ensuring the safety and reliability of the alcohol distillation tower.

[0067] See Figure 3 In this embodiment, the outer ring plate 262 extends horizontally around the circumference of the tower body 210. The outer periphery of the outer ring plate 262 is sealed to the tower body 210 to prevent liquid from falling to the lower side through the gap between the outer ring plate 262 and the tower body 210, thereby improving the gas-liquid mass transfer efficiency.

[0068] See Figure 3 In this embodiment, a receiving groove 2621 may be recessed on the outer periphery of the outer ring plate 262. The receiving groove 2621 is arranged in a ring along the circumference of the outer ring plate 262. The receiving groove 2621 is correspondingly arranged with the output end of the first liquid descending member 252 adjacent to the upper side, so that the liquid output by the first liquid descending member 252 can enter the receiving groove 2621.

[0069] During the downward flow of the liquid, the liquid output from the first liquid descending component 252 first enters the receiving tank 2621. The liquid flows in and fills the receiving tank 2621 first, and then flows evenly towards the moving blade 263 on the central plate 261, thereby ensuring the uniformity of the liquid layer on the outer ring plate 262 and providing a continuous phase interface for gas-liquid contact.

[0070] In some embodiments, the lower end of the first liquid-reducing element 252 extends into the receiving tank 2621 to effectively buffer the fluctuations when the liquid enters the receiving tank 2621, ensuring the smooth flow of liquid on the outer ring plate 262 and ensuring the gas-liquid mass transfer effect.

[0071] See Figure 3 In this embodiment, a first containment weir 264 is provided on the outer ring plate 262. The first containment weir 264 extends circumferentially along the inner periphery of the outer ring plate 262. The first containment weir 264, the outer ring plate 262, and the inner peripheral wall of the tower body 210 enclose a first receiving tank 266. The first receiving tank 266 is used to receive the liquid output from the upper first descending member 252 to form a liquid layer. After the steam flowing from bottom to top enters the first receiving tank 266 through the rising gas channel, it undergoes mass and heat transfer with the horizontally flowing liquid, thereby ensuring the stability of each component in the distillation liquid and effectively improving the distillation efficiency and quality.

[0072] See Figure 3 In this embodiment, in the horizontal direction, the outer ring plate 262 is provided with multiple float valves inside the receiving groove 2621. These float valves constitute the air lifting channels. The multiple float valves include multiple T-shaped float valves 2622, multiple first circular float valves 2623, and multiple strip float valves 2624 arranged at intervals. In the direction away from the center of the outer ring plate 262, the outer ring plate 262 is sequentially provided with strip float valves 2624, first circular float valves 2623, and T-shaped float valves 2622 arranged in a ring along its circumference.

[0073] In the horizontal direction, when the liquid in the first receiving tank 266 flows from the outer periphery toward the living leaf 263, it passes through the T-type float valve 2622, the first circular float valve 2623 and the strip float valve 2624 in sequence to transfer mass and heat with the steam output by each float valve, thereby adjusting the composition of the steam that finally passes through the second tray 260, adjusting the alcohol concentration and flavor components of the final distillate, and meeting the production optimization of different types of wine.

[0074] See Figure 3 In this embodiment, a connecting hole is provided on the outer ring plate 262. The T-type float valve 2622 includes a fixing frame and a T-type valve plate. The fixing frame is fixedly connected to the outer ring plate 262 and is provided corresponding to the connecting hole. The T-type valve plate is movably connected to the fixing frame. Under the action of gravity and liquid pressure, the T-type valve plate can fall and adhere to the outer ring plate 262 to seal the connecting hole and prevent liquid leakage. When the steam pressure on the lower side of the outer ring plate 262 is too high, it can squeeze the T-type valve plate and move the T-type valve plate away from the outer ring plate 262, thereby opening the connecting hole, so that the steam on the lower side can enter the liquid layer through the connecting hole for mass and heat transfer. In addition, the T-type valve plate can also swing at a small angle in the horizontal direction, so that the steam can tilt and swing out under the guidance of the T-type valve plate, so that the steam can drive the liquid to flow in a swirling manner.

[0075] Multiple T-shaped float valves 2622 on the outer ring plate 262 form a ring-shaped float valve assembly. The opening direction of the multiple T-shaped valve plates in the float valve assembly is all towards the center of the outer ring plate 262, so that the steam flowing upward through the connecting hole is also inclined towards the center of the outer ring plate 262. This allows the steam output from the T-shaped float valves 2622 to smoothly push the liquid layer towards the center of the outer ring plate 262, increasing the flow velocity of the liquid layer. This ensures that the steam output from the float valves continuously transfers mass and heat with the newly flowing liquid, guaranteeing the mass and heat transfer effect and effectively improving the circulating distillation effect and distillation efficiency of the liquid in the distillation space 211.

[0076] In some embodiments, the T-type float valve 2622 can improve the removal capacity of low-volatility higher alcohols and long-chain fatty acid esters from steam, making the liquor such as vodka and rum purer and reducing the bitter taste in the liquor.

[0077] See Figure 3 In this embodiment, multiple first circular float valves 2623 on the outer ring plate 262 form an annular float valve group. The float valve group composed of the first circular float valves 2623 is located inside the float valve group composed of T-type float valves 2622. The structure of the first circular float valve 2623 is similar to that of the T-type float valve 2622, except that the valve plate of the first circular float valve 2623 is circular, and the steam output by the first circular float valve 2623 is discharged upward along both sides of the circular valve plate. In the horizontal direction, the steam output by one first circular float valve 2623 is directed towards two adjacent first circular float valves 2623.

[0078] At this time, the liquid propelled by the T-type float valve 2622 flows towards the two adjacent first circular float valves 2623 under the action of the steam output from both sides of the first circular float valve 2623. On the one hand, the steam output from the first circular float valve 2623 can transfer mass and heat with the liquid; on the other hand, the liquid at one of the first circular float valves 2623 can flow towards the other adjacent first circular float valves 2623 under the propulsion of the steam and impact each other, thereby further improving the homogeneity of the components in the liquid and improving the distillation effect of the liquor distillation column 10.

[0079] In some embodiments, the steam output from both sides of the first circular float valve 2623 can form turbulent bubbling to effectively improve mass transfer efficiency, and the fluctuation stability of the steam output speed is strong, making it less prone to leakage. It can accurately control the ethanol concentration rate and avoid over-distillation of the distillate.

[0080] See Figure 3 In this embodiment, multiple strip-shaped float valves 2624 on the outer ring plate 262 form an annular float valve group. The float valve group composed of strip-shaped float valves 2624 is located inside the float valve group composed of the first circular float valves 2623. The structure of the strip-shaped float valve 2624 is similar to that of the T-type float valve 2622, except that the valve plate of the strip-shaped float valve 2624 is rectangular, and the steam output by the strip-shaped float valve 2624 is sprayed out in a curtain shape. In the horizontal direction, the curtain-shaped steam output by the strip-shaped float valve 2624 flows towards the movable blade 263, which can effectively enhance the contact range between steam and liquid and increase mass transfer efficiency.

[0081] In some embodiments, the vapor-liquid contact area of ​​the output steam and liquid from the strip float valve 2624 is larger than that of the first circular float valve 2623 and the T-type float valve 2622. The strip float valve 2624 has the highest mass transfer efficiency and can rapidly increase the concentration of ethanol.

[0082] See Figure 3 In this embodiment, the center plate 261 can be circular. In the horizontal direction, the center plate 261 can be located at the center of the column body 210 to facilitate the uniform arrangement of multiple movable blades 263 and to allow multiple flow channels to be uniformly arranged around the periphery of the center plate 261. This facilitates uniform mass transfer between the vapor output from the multiple flow channels and the liquid in the liquid layer, ensuring the stability of the distillate and reducing fluctuations in the components of the distillate.

[0083] See Figure 3In this embodiment, a tray outlet 2611 is provided in the middle of the central tray 261. The second tray 260 also includes a second downcomer 268. The input end of the second downcomer 268 is connected to the tray outlet 2611, and the second downcomer 268 is used to output the liquid on the central tray 261 to the lower rectification space 211. The second downcomer 268 is used to input the liquid on the upper side of the second tray 260 to other trays on the lower side or to the bottom of the rectification space 211, so as to reduce the impact kinetic energy of the output liquid.

[0084] In some embodiments, the second liquid-receiving element 268 may be a tubular structure for receiving and guiding liquid.

[0085] See Figure 3 In this embodiment, a plurality of second circular float valves 2612 are provided on the central plate 261 in a direction away from the center of the central plate 261, so that the second circular float valves 2612 form a gas rising channel, thereby enabling the liquid layer flowing into the central plate 261 to fully transfer mass and heat with the steam output from the second circular float valves 2612, ensuring the distillation effect of the wine. The structure of the second circular float valves 2612 is the same as that of the first circular float valve 2623 described above, so as to allow the steam on the lower side to flow upward.

[0086] In some embodiments, a plurality of second circular float valves 2612 are arranged in a ring-shaped interval around the circumference of the central plate 261, so that the plurality of second circular float valves 2612 form a float valve group. In the direction away from the center of the central plate 261, the plurality of float valve groups composed of second circular float valves 2612 are sequentially spaced. In other embodiments, the second circular float valves 2612 in the plurality of float valve groups on the central plate 261 are sequentially and alternately arranged to further improve the mass transfer effect of liquid to vapor on the central plate 261 and ensure the uniformity of gas-liquid mass transfer.

[0087] See Figure 3 In this embodiment, a second containment weir 265 is provided on the central plate 261. The second containment weir 265 is arranged in a ring around the outer periphery of the central plate. The movable leaf 263, the second containment weir 265, and the first containment weir 264 can be closed to form a second receiving groove 267. The second receiving groove 267 is used to receive liquid overflowing from the adjacent first receiving groove 266.

[0088] The operator can rotate the movable leaf 263 to close the flow channel, allowing steam below the movable leaf 263 to enter the second container 267 through the rising gas channel for mass and heat transfer with the liquid layer. The operator can also rotate the movable leaf 263 to open the flow channel, allowing steam below the movable leaf 263 to enter the second container 267 through both the rising gas channel and the flow channel for mass and heat transfer with the liquid layer. The operator can adjust the opening of the flow channel to adjust the mass transfer time and efficiency between the steam and the liquid layer, thereby adjusting the composition of the steam, the alcohol concentration and flavor substance content in the distillate, achieving efficient production of different varieties and flavor profiles of alcoholic beverages, and improving the versatility of the alcoholic beverage distillation column 10.

[0089] See Figure 3 In this embodiment, in the vertical direction, the height of the top of the second containment weir 265 is lower than the height of the top of the first containment weir 264, so that the liquid in the first containment tank 266 can enter the second containment tank 267, and the liquid in the second containment tank 267 can enter the upper side of the center plate 261, thus avoiding the mixing of liquid layers on the upper side of the center plate 261, the movable leaf 263 and the outer ring plate 262.

[0090] In some embodiments, the thickness of the liquid layer in the first receiving tank 266 is greater than the thickness of the liquid layer in the second receiving tank 267, so as to increase the gas-liquid interface, accelerate the gas-liquid surface renewal rate, thereby intensifying the exchange rate of light fruit flavor esters, heavy aldehydes and higher alcohols, improving the flavor homogeneity and blending of the distillate, and reducing the radial component deviation of the distillate.

[0091] In some embodiments, the second containment weir 265 and the first containment weir 264 can be inclined to avoid the movable leaf 263, thus ensuring the rotation of the movable leaf 263. In other embodiments, the cross-sections of the second containment weir 265 and the first containment weir 264 can be arc-shaped in the vertical direction to avoid the movable leaf 263 and ensure the stable rotation of the movable leaf 263. In other embodiments, the horizontal cross-sections of the second containment weir 265 and the first containment weir 264 can be wavy in the horizontal direction to avoid the movable leaf 263 and ensure the stable rotation of the movable leaf 263.

[0092] See Figure 3 In this embodiment, the center plate 261 can be connected to the outer ring plate 262 or the tower body 210 through a connecting structure to ensure the structural strength and reliability of the center plate 261. In another embodiment, the center plate 261 can be supported within the outer ring plate 262 by multiple rotating shafts, thereby ensuring the structural stability and reliability of the center plate 261.

[0093] See Figure 3In this embodiment, the movable leaf 263 extends radially along the central plate 261 in a long strip shape. Multiple movable leaves 263 are spaced apart and arranged around the periphery of the central plate 261. The side of the movable leaf 263 facing the central plate 261 is adapted to the outer periphery of the central plate 261 in an arc shape. When multiple movable leaves 263 are sealed together, the side of the movable leaf 263 facing the central plate 261 can adhere to the central plate 261, thereby achieving a sealed connection between the movable leaf 263 and the central plate 261. The side of the movable leaf 263 facing the outer ring plate 262 is adapted to the inner periphery of the outer ring plate 262 in an arc shape. When multiple movable leaves 263 are sealed together, the side of the movable leaf 263 facing the outer ring plate 262 can adhere to the outer ring plate 262, thereby achieving a sealed connection between the movable leaf 263 and the outer ring plate 262.

[0094] See Figure 3 In this embodiment, multiple third circular float valves 2631 are provided on the blade 263 in the direction away from the center of the central plate 261. The third circular float valves 2631 constitute the air-lifting channel on the blade 263, thereby facilitating the steam on the lower side of the blade 263 to enter the liquid layer on the upper side of the blade 263 for mass and heat transfer. The structure of the third circular float valves 2631 is the same as that of the first circular float valve 2623 described above, so that the third circular float valves 2631 can allow the steam on the lower side to flow upward and pass through the blade 263.

[0095] In some embodiments, a plurality of third circular float valves 2631 on the movable leaf 263 are arranged sequentially at intervals along the axial direction of the movable leaf 263 to assist in gas-liquid mass transfer.

[0096] See Figure 3 In this embodiment, the liquor distillation column 10 also includes a drive assembly. The drive structure can be a centrally radial linkage structure for synchronously driving the rotation of multiple rotating blades.

[0097] In some embodiments, the drive assembly may include multiple rotating shafts and a drive member 271. The rotating shafts are located below the center plate 261; the multiple rotating shafts are respectively disposed around the periphery of the center plate 261 corresponding to multiple movable leaves 263. The rotation axis of the rotating shaft passes through the center of the center plate 261 and extends along the interval between the outer ring plate 262 where the corresponding movable leaf 263 is located and the center plate 261. Both ends of the rotating shaft are rotatably connected to the center plate 261 and the outer ring plate 262, respectively, and the rotating shaft is connected to the movable leaf 263 to drive the movable leaf 263 to rotate. The drive member 271 is drively connected to the multiple rotating shafts to drive the rotating shafts to rotate, thereby facilitating the operator to adjust the rotation angle of the movable leaf 263, and enabling the operator to adjust the taste and alcohol content of different wines in real time.

[0098] In other embodiments, a rotating shaft is positioned on one side of each of the multiple blades 263 in the arrangement direction of the blades 263, allowing the blades 263 to rotate about the rotating shaft. The blades 263 can rotate to a horizontal position, so that the side of one blade 263 away from the rotating shaft can seal against another blade 263, thus ensuring a tight seal between the two blades 263. The blades 263 can also rotate at an angle to the horizontal plane, allowing a flow channel for steam to be formed between adjacent blades 263.

[0099] In other embodiments, when all the multiple blades 263 are rotated to a horizontal position, the upper surfaces of the multiple blades 263 are at the same height as the center plate 261 and the outer ring plate 262.

[0100] In some embodiments, the rotating shaft may be disposed on the movable leaf 263. The movable leaves 263 are all arranged at an angle in the arrangement direction of the plurality of movable leaves 263.

[0101] In some embodiments, the plurality of movable leaves 263 may include a first movable leaf 263, a second movable leaf 263, and a third movable leaf 263 arranged sequentially. The first movable leaf 263, the second movable leaf 263, and the third movable leaf 263 are all inclined. The side of the first movable leaf 263 facing the second movable leaf 263 can be attached to the upper side of the second movable leaf 263, and the side of the second movable leaf 263 facing the third movable leaf 263 can be attached to the upper side of the third movable leaf 263, so that the first movable leaf 263, the second movable leaf 263, and the third movable leaf 263 can be sealed and attached.

[0102] Furthermore, when the multiple movable leaves 263 rotate, the first movable leaf 263 can rotate around the rotation axis, so that the side of the first movable leaf 263 facing the second movable leaf 263 moves upward away from the second movable leaf 263, thereby opening the flow channel between the first movable leaf 263 and the second movable leaf 263. The second movable leaf 263 can rotate around the rotation axis, so that the side of the second movable leaf 263 facing the third movable leaf 263 moves upward away from the third movable leaf 263, thereby opening the flow channel between the second movable leaf 263 and the third movable leaf 263.

[0103] See Figure 3 In this embodiment, the drive assembly may further include multiple transmission rods 273. The multiple transmission rods 273 are arranged corresponding to multiple movable blades 263. The transmission rods 273 extend radially along the outer ring plate 262, one end of the transmission rod 273 is connected to the rotating shaft, and the other end of the transmission rod 273 extends out of the tower body 210. A drive member 271 is disposed on the outside of the tower body 210 to be connected to the transmission rods 273, thereby enabling the operator to control the rotation angle of the movable blades 263 through the drive member 271, the transmission rods 273, and the rotating shaft.

[0104] In some embodiments, the transmission rod 273 avoids the rising gas channel on the outer ring plate 262 to prevent the transmission rod 273 from affecting the entry of steam into the first receiving tank 266 through the rising gas channel, thereby ensuring the stability of mass and heat transfer between steam and liquid on the outer ring plate 262 and reducing the fluctuation of each component in the distillate.

[0105] In other embodiments, the transmission rod 273 and the outer ring plate 262 are spaced apart in the vertical direction to avoid the float valve.

[0106] See Figure 3 In this embodiment, multiple second trays 260 are spaced apart in the vertical direction inside the tower body 210 to achieve multiple distillations of the distillate and ensure the distillation effect of the wine distillation tower 10.

[0107] The number of T-type float valves 2622 and strip float valves 2624 in the second tray 260 at the top of the distillation space 211 is less than the number of T-type float valves 2622 and strip float valves 2624 in the second tray 260 at the bottom of the distillation space. The number of first circular float valves 2623 in the second tray 260 at the top of the distillation space 211 is greater than the number of first circular float valves 2623 in the second tray 260 at the bottom of the distillation space. This allows the vapor to further increase the ethanol concentration rate during its upward flow, reduce fluctuations in the alcohol concentration in the distillate, and ensure the alcohol concentration and taste of the final product.

[0108] See Figure 3 In this embodiment, at least three first trays 250 are disposed on the upper side of any second tray 260. At least three first trays 250 are disposed on the lower side of any second tray 260, thereby enabling the second tray 260 with adjustable flow channels to cooperate with multiple non-adjustable first trays 250 to achieve multiple cyclic distillations of dealdehyde-treated wine, ensuring the stability of the alcohol concentration and flavor components of the distillate. Furthermore, the wine distillation column 10 can be used to produce wines of different varieties and flavors, improving the applicability and versatility of the wine distillation column 10.

[0109] In some embodiments, when the lower side of the first tray 250 is another first tray 250, the first liquid descending member 252 of the upper first tray 250 is disposed opposite to the buffer groove 254 of the lower first tray 250 so that the liquid on the upper first tray 250 flows smoothly into the lower first tray 250.

[0110] In some embodiments, when the second tray 260 is below the first tray 250, the first liquid descending member 252 of the upper first tray 250 is disposed opposite to the receiving groove 2621 of the lower second tray 260 so that the liquid on the upper first tray 250 flows smoothly into the lower second tray 260.

[0111] In some embodiments, the second downcomer 268 of the second tray 260 can be bent. When the first tray 250 is below the second tray 260, the output end of the second downcomer 268 can be positioned relative to the buffer tank 254, so that the liquid output by the second downcomer 268 first enters the buffer tank 254 and then overflows into the working tank 253, thereby ensuring the stability of the liquid layer on the lower first downcomer 252.

[0112] In this embodiment, the liquor distillation column 10 may further include a collection component. The collection component includes a first collection tray 281, a baffle condenser ring 282, a second collection tray 283, and a collection pipe 284, all disposed within the distillation space 211. The first collection tray 281 is horizontally disposed below the baffle condenser ring 282 and connected to the inner peripheral wall of the column body 210. A collection groove is provided on the first collection tray 281. A collection connection port is provided at the bottom of the collection groove on the first collection tray 281. The baffle condenser ring 282 is disposed above the first collection tray 281. The baffle condenser ring 282 is arranged in a ring shape along the horizontal direction. The baffle condenser ring 282 is connected to an external cold source, allowing for the exchange of refrigeration media between the baffle condenser ring 282 and the external cold source, thereby ensuring the temperature stability of the baffle condenser ring 282. The baffle condenser ring 282 is used to condense the vapor passing through the first collection tray 281 into a collection liquid, and to collect the collection liquid into the collection tank. The second collection tray 283 is located below the first collection tray 281, and a receiving tank is provided inside the second collection tray 283. The receiving tank is located below the collection tank to receive the collection liquid output from the collection port. A collection pipe 284 is located below the second collection tray 283. One end of the collection pipe 284 is connected to the bottom of the receiving tank, and the other end of the collection pipe 284 passes through the side wall of the tower body 210 and extends to the outside, so as to facilitate the output of the collection liquid to the outside.

[0113] When the operator connects the baffle condenser ring 282 to an external cold source, the baffle condenser ring 282 can condense the flowing vapor to form a collected liquid. Under gravity, the collected liquid falls into the collection tank of the first collection tray 281 and is then output through the collection connection port to the receiving tank of the second collection tray 283. During the slow flow of the collected liquid into the receiving tank, gas in the collected liquid at the bottom of the receiving tank flows out as liquid, thus purifying the collected liquid. Afterwards, the collected liquid at the bottom of the receiving tank is output to the outside through the collection pipe 284, so that the collected liquid can be mixed with other wine components to form wines with different flavors and tastes, increasing the product variety and function of the wine distillation column 10 and improving its versatility.

[0114] In some embodiments, the collection component avoids the first liquid descending element 252 so that the collection component is only used to collect the trapping liquid formed by steam condensation, thereby avoiding the liquid transported by the first liquid descending element 252 from affecting the collection of the trapping liquid, and adjusting the alcohol concentration and flavor substances of the finished wine in real time.

[0115] In some embodiments, in the horizontal direction, the connection between the collection tube 284 and the second collection tray 283 is spaced apart from the collection port, and the liquid output from the collection port is discharged to the outside through the collection tube 284 after flowing and purification.

[0116] In some embodiments, a one-way shut-off valve is provided on the collection pipe 284. The operator can close the collection pipe 284 using the one-way shut-off valve. At this time, the operator can connect the baffle condenser ring 282 to an external cold source, so that the collected liquid condensed by the baffle condenser ring 282, after entering the receiving tank, can overflow from the second collecting tray 283 and fall into the lower rectification space 211, thereby achieving repeated distillation of the vapor.

[0117] In this embodiment, an extractant inlet may also be provided at the bottom of the column body 210. The extractant inlet is used to introduce supercritical carbon dioxide into the rectification space 211. The supercritical carbon dioxide flows from bottom to top in the rectification space 211 to extract the dealdehyde wine and form a rectification liquid.

[0118] When the staff inputs supercritical carbon dioxide, the supercritical carbon dioxide flows from bottom to top, passing through the first tray 250 and the second tray 260 in sequence. The supercritical carbon dioxide can enter the liquid layer on the upper side of the tray through the flow channel and the float valve, thereby realizing the extraction of dealdehyde wine.

[0119] Once the supercritical carbon dioxide flows to the top of the distillation space, it enters the condenser assembly 230 to condense the supercritical carbon dioxide and assist in the separation of carbon dioxide from the distillate.

[0120] See Figures 1 to 3In this embodiment, after the dealdehyde-removed wine enters the wine distillation column 10, it flows from top to bottom within the distillation space 211. Upon entering the distillation space 211, the liquid first flows onto the first tray 250 and is then transported via the first downcomer 252 to the receiving tank 2621 of the lower second tray 260. The liquid extends circumferentially along the second tray 260 within the receiving tank 2621. The liquid in the receiving tank 2621 can overflow, forming a liquid layer on the outer ring plate 262. Subsequently, the thickness of the liquid layer on the outer ring plate 262 gradually increases and crosses the first containment weir 264 into the second receiving tank 267. The liquid in the second receiving tank 267 forms a liquid layer, and as the thickness gradually increases, the liquid in the second receiving tank 267 can cross the second containment weir 265 into the central plate 261. Finally, the liquid on the central plate 261 is output to the bottom of the distillation space 211 via the second downcomer 268.

[0121] The liquid at the bottom of the distillation space 211 evaporates into steam under the action of the reboiling component 220. The steam flows from bottom to top in the distillation space 211. When the steam passes through the second tray 260, it can transfer mass and heat to the liquid layers on the outer ring plate 262, the movable blade 263, and the central plate 261, respectively. This allows the steam in different regions to transfer mass and heat with liquids of different material compositions and temperatures, thereby controlling the content of each component of the steam in different regions.

[0122] The vapor extending beyond the second tray 260 enters the liquid layer on the first tray 250 through the rising channel, where it undergoes mass and heat transfer, further regulating the composition of the vapor. The vapor then passes through the first tray 250 and gathers at the top of the rectification space 211. This vapor then enters the condenser 232 through the second inlet pipe 231, where it condenses into condensate. The condenser 232 returns the condensate to the rectification space 211, achieving a circulating rectification of the liquid within the space. Furthermore, the condenser 232 discharges the distillate to downstream units through the second outlet pipe 242, allowing the wine to be washed and processed to form the finished wine.

[0123] Furthermore, when staff use the liquor distillation column 10 to distill different varieties and flavors of dealdehyded alcohol, they can adjust the opening of the flow channel and the speed of the steam output by rotating the movable blade 263, as well as the mass transfer efficiency between the steam and the liquid layer in the second container 267. This allows them to adjust the composition of each substance in the steam passing through the second tray 260, facilitating real-time adjustment of the alcohol concentration and the composition of various flavor substances in the distillate. This increases the diversity of the final product liquor and improves the applicability and versatility of the liquor distillation column 10.

[0124] See Figures 1 to 3 This application also provides a liquor distillation system, which includes a mash tower 30, a degassing tower 40, and a liquor distillation tower 10 as described above. The mash tower 30 receives external mash and heats it to evaporate it. Crude liquor gas containing aldehydes and fusel oils is collected from the top of the mash tower 30. The degassing tower 40 is connected to the mash tower 30 to receive the crude liquor gas output from the mash tower 30. The degassing tower 40 condenses the crude liquor gas and separates acetaldehyde, light sulfides, and other first-stage waste gases, discharging the waste gases externally. After removing impurities from the crude liquor gas, the degassing tower produces dealdehyde-removed liquor. The liquor distillation tower 10 is connected to the degassing tower 40 and receives the dealdehyde-removed liquor output from the degassing tower 40. The liquor distillation tower 10 is used to distill the dealdehyde-removed alcohol into a distillate.

[0125] Workers can adjust the rotation angle of the rotating leaf 263 and the opening of the flow channel in real time through the drive component to change the gas-liquid mass transfer efficiency on the second tray 260, thereby precisely controlling the separation and retention ratio of flavor components such as aldehydes, fusel oils, and aroma esters, according to the required variety and flavor indicators of the produced liquor. The liquor distillation column 10 can adjust the alcohol concentration and flavor component content of the final distillate, enabling the distillate produced by the liquor distillation system to be used in the production of various liquors with different flavors and tastes, improving the versatility of the liquor distillation system and reducing the production cost of different liquors.

The separation tower 50 receives the distillate output from the wine distillation tower 10 and heats the distillate to form alcohol vapor. High-boiling-point fusel oils in the distillate are enriched and separated within the separation tower 50 to form waste liquid, which is then discharged outside the separation tower 50.

[0128] In the relevant technology, the separation tower 50 is a conventional separation tower 50, which is used to receive the distillate and separate some of the fusel oil in the distillate, and will not be discussed here.

The water washing tower 60 is used to receive the alcohol vapor output from the separation tower 50. Process wash water can be introduced at the top of the water washing tower 60, and this process wash water can contact the alcohol vapor to remove residual low-carbon fusel oils and water-soluble impurities from the alcohol vapor through water washing extraction, thereby further improving the purity of the alcohol vapor.

[0130] In the relevant technology, the water washing tower 60 is a conventional water washing tower 60, which is used to receive alcohol vapor and further remove impurities from the alcohol vapor to increase the alcohol concentration in the alcohol vapor, and will not be discussed here.

The refining tower 70 is used to receive the purified alcohol vapor output from the washing tower 60, and further refine and condense it to form the finished wine.
