Example implementations can, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example implementations to those skilled in the art.

[0041] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the

[0042] The disclosure will be further described with reference to the drawings and specific examples. It is to be noted that the technical features involved in each of the embodiments of the disclosure described below can be combined with each other as long as there is no conflict. The embodiments described below with reference to the drawings are exemplary and are intended to explain the disclosure, and should not be understood as limiting the disclosure.

[0043] As shown in Figures 1 to 8 The present disclosure provides a de-flavoring strong liquor distillation column device 1, which comprises a column body 2 and a plurality of upper trays 3.

[0044] As shown in Figure 1 The column body 2 comprises a feed inlet and a top outlet, and the feed inlet is located at the middle lower part of the column body 2. The axis of the column body 2 extends in the direction from the top to the bottom thereof.

[0045] It is to be noted that the middle lower part of the column body 2 refers to the area below the center line of the column body 2, and the feed inlet in the present disclosure can be arranged at any position in the middle lower part of the column body 2 according to actual conditions, and the wine liquid enters the inside of the column body 2 through the feed inlet.

[0046] The top outlet is located at the top of the column body 2, and specifically, a head 21 can be arranged at the top of the column body 2 to seal the column body 2, and the top outlet can be arranged on the head 21. The wine liquid is distilled into wine vapor in the column body 2, and the wine vapor moves upwards from bottom to top towards the top outlet in the column body 2.

[0047] The plurality of upper trays 3 are arranged in the column body 2 and located between the feed inlet and the top outlet, and the plurality of upper trays 3 are arranged at intervals along the axis of the column body 2. Specifically, the intervals between the upper trays 3 can be equal, but are not limited thereto, and the intervals between the upper trays 3 can also be unequal, and can be set according to actual conditions.

[0048] As Figure 2 shown in the drawings, in the present disclosure, a plurality of communication holes 31 are arranged on the upper tray 3, and the plurality of communication holes 31 are arranged through the corresponding upper tray 3. During the distillation of the wine liquid, the wine liquid vapor can rise to the top of the tower body 2 through the communication holes 31 on each tray.

[0049] Further, in the present disclosure, a plurality of draft tubes 32 are arranged on at least the upper tray 3 near the tower top discharge port, and the plurality of draft tubes 32 are arranged in an array on the corresponding upper tray 3 to maintain the vapor-liquid balance of the upper tray 3. The draft tube 32 is open at both ends and hollow inside to form a passage, and the draft tube 32 is arranged through the corresponding upper tray 3. Specifically, the draft tube 32 in the present disclosure can be arranged in the communication hole 31 on the tray. The height of the draft tube 32 in the present disclosure is greater than the thickness of the upper tray 3, and the draft tube 32 is made of copper-containing material.

[0050] It should be noted that the height of the draft tube 32 refers to the size along its own axial direction. With the view direction as the reference, the axial direction of the draft tube 32 is parallel to the axial direction of the tower body 2. Figure 1

[0051] The present disclosure can make the wine liquid vapor move from bottom to top towards the tower top discharge port through the draft tube 32 during the distillation of the wine liquid in the tower body 2, and the copper in the draft tube 32 reacts with the dimethyl sulfide in the wine liquid vapor, thereby purifying the odor carried by the dimethyl sulfide in the wine liquid vapor. That is, the present disclosure arranges the draft tube 32 on the upper tray 3 to increase the contact time of the wine liquid vapor with the copper material and increase the reaction time between the dimethyl sulfide in the wine liquid vapor and the copper, so as to promote the sufficient reaction between the dimethyl sulfide in the wine liquid vapor and the copper, thereby removing the dimethyl sulfide in the wine liquid vapor, and better purifying the odor carried by the dimethyl sulfide in the wine liquid vapor.

[0052] For example, the draft tube 32 can be pure copper or red copper to prolong the service life of the draft tube 32, but is not limited thereto. The draft tube 32 in the present disclosure can also be made of stainless steel with a copper-plated surface to reduce the manufacturing cost of the draft tube 32.

[0053] As Figures 3 to 4 shown in the drawings, in the present disclosure, a plurality of communication holes 31 are arranged on the upper tray 3, and the plurality of communication holes 31 are arranged through the corresponding upper tray 3. During the distillation of the wine liquid, the wine liquid vapor can rise to the top of the tower body 2 through the communication holes 31 on each tray. ​

[0054] Further, when the wine liquid vapor flows inside the riser 32, since there is a case that part of the wine liquid vapor has already passed through the through hole 321 at the bottom of the riser 32 to leave the riser 32 before reaching the top surface of the riser 32, at this time, the wall thickness of the riser 32, that is, the thickness of the side wall of the through hole 321, can be appropriately increased, so that the reaction time between the wine liquid vapor leaving the inside of the riser 32 from the through hole 321 at the bottom of the riser 32 and the side wall of the through hole 321 can be increased, so as to better purify the odor carried by the dimethyl sulfide in the wine liquid vapor. At the same time, the increase of the wall thickness of the riser 32 can also prolong the service life of the riser 32, so as to reduce the frequency of replacing the riser 32 and reduce the maintenance cost.

[0055] For example, the wall thickness of the riser 32 in the present disclosure can be 2mm-3mm, such as 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, etc., but is not limited thereto, and the wall thickness of the riser 32 can be determined according to actual conditions.

[0056] In the embodiments of the present disclosure, the specific design values of the inner diameter and the height of the riser 32 can be determined according to the amount of the wine liquid vapor rising, that is, according to the processing amount of the wine liquid vapor in the tower body 2.

[0057] For example, the inner diameter of the riser 32 in the present disclosure can be DN25-DN200, such as DN25, DN50, DN75, DN100, DN125, DN150, DN175, DN200, etc., but is not limited thereto, and the inner diameter of the riser 32 can be determined according to actual conditions.

[0058] It should be noted that the number of the riser 32 on the upper tray 3 is related to the amount of the wine liquid vapor rising, and the greater the amount of the wine liquid vapor rising, the greater the number of the riser 32 on the upper tray 3. Therefore, the present disclosure can set the riser 32 in part of the communication holes 31 on the upper tray 3 according to actual needs, so as to save cost. However, the present disclosure can also set one riser 32 in each of all the communication holes 31 on the upper tray 3.

[0059] For example, the present disclosure can be provided with the draft tube 32 on the communication hole 31 of the upper tray 3 in the existing column body 2, when the number of the communication hole 31 of the upper tray 3 in the existing column body 2 is greater than the number of the draft tube 32 on the upper tray 3, the draft tube 32 can be provided in part of the communication hole 31 on the upper tray 3 according to actual needs, so that the odor carried by the dimethyl sulfide in the liquor can be purified by the draft tube 32, and the structure of the existing column body 2 can be utilized, the upper tray 3 in the column body 2 is avoided to be replaced, and the manufacturing cost of the odor-removing liquor distillation column equipment 1 is reduced.

[0060] In addition, it should be noted that the present disclosure can be provided with the draft tube 32 in part of the upper tray 3 close to the top discharge port, the reaction time between the dimethyl sulfide in the liquor vapor and copper can be increased by the draft tube 32, so that the odor carried by the dimethyl sulfide in the liquor vapor can be better purified, and the manufacturing cost of the odor-removing liquor distillation column equipment 1 can be reduced. However, the present disclosure can also be provided with the draft tube 32 on all upper trays 3.

[0061] For example, as shown in FIG. 1, Figure 1 The present disclosure can be provided with eight upper trays 3 in the column body 2, and a plurality of draft tubes 32 can be provided on four, five or six upper trays 3 closest to the top discharge port, but the present disclosure can also be provided with a plurality of draft tubes 32 on all upper trays 3.

[0062] In some embodiments of the present disclosure, the bottom of the draft tube 32 can be flush with the bottom of the corresponding upper tray 3, and the top of the draft tube 32 can extend upward beyond the top of the corresponding upper tray 3.

[0063] However, in other embodiments of the present disclosure, the bottom of the draft tube 32 can be lower than the bottom of the upper tray 3, which can be determined according to actual conditions.

[0064] In the present disclosure, the draft tube 32 and the upper tray 3 are connected to each other.

[0065] The plurality of draft tubes 32 and the corresponding upper tray 3 can be stamped on a plate at one time, that is, the plurality of draft tubes 32 and the corresponding upper tray 3 are integrally formed, so that the manufacturing process of the odor-removing liquor distillation column equipment 1 can be simplified, and the manufacturing cost of the odor-removing liquor distillation column equipment 1 can be reduced. Moreover, by integrally forming the plurality of draft tubes 32 and the corresponding upper tray 3, the connection between the draft tube 32 and the corresponding upper tray 3 can be stamped into a smooth arc, so that a dead angle can be avoided between the draft tube 32 and the upper tray 3, and the cleaning of the internal structure of the column body 2 after distillation can be facilitated.

[0066] In addition, the present disclosure can also form the upper tray 3 and the riser 32 separately, and set the riser 32 in the corresponding communication hole 31 on the upper tray 3. The connection between the upper tray 3 and the riser 32 can be achieved by welding, buckling or other methods. In order to avoid the formation of dead angles between the riser 32 and the upper tray 3, the present disclosure can set the connection between the riser 32 and the upper tray 3 as a smooth arc shape to facilitate cleaning.

[0067] In the present disclosure, the top outlet is provided with a top outlet pipe 41 and a maintenance pipe 42. The inlet end of the maintenance pipe 42 is opposite to the top outlet, and the outlet end of the maintenance pipe 42 is connected to the top outlet pipe 41. The maintenance pipe 42 is made of red copper. The wine vapor that leaves the top outlet can enter the top outlet pipe 41 through the maintenance pipe 42. By setting the maintenance pipe 42, the reaction time between dimethyl sulfide in the wine vapor and copper can be increased, so that the odor carried by dimethyl sulfide in the wine vapor can be better purified.

[0068] In the present disclosure, the maintenance pipe 42 is arranged upwardly from the top outlet in a meandering manner. Specifically, the maintenance pipe 42 can be arranged in a bending, coiled, spiral or other manner.

[0069] For example, the maintenance pipe 42 in the present disclosure can include a plurality of first pipe segments arranged in parallel and spaced apart, and a second pipe segment connecting adjacent two first pipe segments. The axis of the first pipe segment extends along a straight line, and the length of the first pipe segment is greater than the length of the second pipe segment. By arranging the maintenance pipe 42 upwardly from the top outlet in a meandering manner, the present disclosure prolongs the residence time of the wine vapor in the maintenance pipe 42, so that the dimethyl sulfide in the wine vapor fully reacts with the copper in the maintenance pipe 42 to purify the odor carried by the dimethyl sulfide in the wine vapor. At the same time, the occupied space of the maintenance pipe 42 can be reduced, so that the overall occupied space of the deodorized liquor distillation tower device 1 can be reduced, thereby improving the applicability of the deodorized liquor distillation tower device 1.

[0070] It should be noted that the inner diameter and length of the maintenance pipe 42 depend on the content of dimethyl sulfide in the wine vapor. The present disclosure can calculate the size of the device by design to enable the dimethyl sulfide in the wine vapor to fully react with the copper in the maintenance pipe 42 and purify the odor carried by the dimethyl sulfide in the wine vapor, while reducing the consumption of the maintenance pipe 42, thereby reducing the manufacturing cost. Since the inlet end of the maintenance pipe 42 is opposite to the top outlet, the diameter of the maintenance pipe 42 can be equal to the hole diameter of the top outlet for easy installation.

[0071] In addition, since the top of the tower body 2 is in a high temperature and high pressure state during operation, the present disclosure can also set a pipe support to fix and insulate the maintenance pipe 42.

[0072] The deodorized liquor distillation column device 1 can further comprise a first condenser 43 and a reflux liquid pipe 44. The first condenser 43 is connected to the overhead outlet pipe 41 to liquefy the liquor vapor flowing out of the overhead outlet.

[0073] Further, the first condenser 43 can be connected to a product outlet pipe 45. The product outlet pipe 45 can be used to collect the liquor product obtained after liquefaction.

[0074] The reflux liquid pipe 44 is connected to the tower body 2 at one end and to the first condenser 43 at the other end. The reflux liquid pipe 44 can be used to return part of the liquor condensed in the first condenser 43 to the tower body 2, so that the part of the liquor condensed can be repeatedly distilled in the tower body 2 to increase the reaction time between dimethyl sulfide and copper in the liquor, thereby purifying the odor carried by dimethyl sulfide in the liquor vapor and improving the overall flavor of the product liquor.

[0075] The first extraction structure 51 can be arranged between the upper tray 3 and the overhead outlet. The first extraction structure 51 is used to fix and stack spices to increase the residence time of alcohol vapor in contact with the spices. When the liquor vapor with a certain flow rate, high temperature and high purity flows from bottom to top through the first extraction structure 51, the liquor vapor can vaporize the flavoring substances in the spices to make the flavoring substances in the spices that can be sensed by the nasal cavity be mixed into the liquor vapor.

[0076] It should be noted that the spices arranged in the first extraction structure 51 can be composed of a plurality of light components with low boiling points. During the process of high-temperature fluid flowing through the spices and fully contacting the spices, the light component substances are more likely to be vaporized after high temperature and quickly mixed and carried away by the alcohol vapor.

[0077] The deodorized liquor distillation column device 1 can further comprise a tower kettle 53 and a second extraction structure 52. The tower kettle 53 is arranged at the bottom of the tower body 2 and can contain liquor. The second extraction structure 52 is arranged at the bottom of the tower body 2 to contain spices. The second extraction structure 52 can be soaked in the liquor in the tower kettle 53, and the liquor in the tower kettle 53 can extract the spices in the second extraction structure 52 to make the flavoring substances in the spices that can be sensed by the nasal cavity and the flavoring substances in the spices that can be sensed by the oral cavity be mixed into the liquor. The spices in the second extraction structure 52 can be solid spices.

[0078] Furthermore, this disclosure allows for the simultaneous installation of a first extraction structure 51, a second extraction structure 52, and a distillation vessel 53 within the deflavoring spirit distillation tower equipment 1. This disclosure allows for circulating heating of the distillation vessel 53, ensuring its pressure exceeds the operating pressure at the top of the tower. Under high temperature and high pressure operating conditions, the spirit, acting as an extraction solvent, can extract flavor compounds perceptible to both the nasal cavity and the oral cavity from the flavorings. Specifically, the flavorings, immersed in the spirit, undergo an extraction process involving circulating heating and high-temperature boiling, allowing flavor compounds to dissolve into the spirit, thereby enhancing the flavor of the spirit product. The spirit is distilled to form spirit vapor, which is then purified through multiple upper trays 3 to obtain a purer flavored spirit. The spirit vapor flows upward and contacts the flavorings in the first extraction structure 51, extracting the lighter components of the flavorings and incorporating them into the spirit vapor, thus enhancing the flavor of the spirit product.

[0079] This disclosure, by incorporating a first extraction structure 51 and a second extraction structure 52 within the tower body 2, utilizes extractive distillation and stripping distillation techniques to add various flavor and sensory characteristics to spirits without the addition of artificial chemicals. These sensory characteristics are not only nasal and oral, but also provide a unique enjoyment. Simultaneously, this disclosure reduces the consumption of artificial additives and avoids the negative impact of blending with artificial additives on spirit quality.

[0080] like Figure 1 and Figures 5 to 7 As shown in this disclosure, both the first extraction structure 51 and the second extraction structure 52 may include an extraction cylinder 501, a top cap 502, and a bottom support 503. The extraction cylinder 501 is disposed between the top cap 502 and the bottom support 503 and extends axially along the tower body 2. Multiple arrayed, spaced-apart through holes are provided on the side wall of the extraction cylinder 501 to ensure sufficient contact between the wine vapor and the flavorings inside the extraction cylinder 501. The sides of both the top cap 502 and the bottom support 503 are connected to the inner side wall of the tower body 2.

[0081] For example, the extraction cylinder 501 in this disclosure can be a hollow cylindrical structure made of copper. In this case, the top cap 502 and the bottom support 503 can be arranged in an annular shape with an outer diameter smaller than the inner diameter of the tower body 2, and a grid structure is provided inside the top cap 502 and the bottom support 503.

[0082] The grid structure can be composed of multiple intersecting steel bars welded together, and the grid structure is welded to the top cover 502 and the bottom support 503.

[0083] For example, the bottom support 503 can be welded to the tower body through steel strips at the bottom of the bottom support 503. The top of the top cover 502 can be provided with a few steel plates welded longitudinally, and the inside of the top cover 502 can be provided with steel strips welded transversely, and the top cover 502 is pressed on the extraction cylinder 501.

[0084] The present disclosure sets the extraction cylinder 501 for fixing the flavor. At the same time, by setting the top cover 502 and the bottom support 503 at the top and bottom of the extraction cylinder 501 respectively, the extraction cylinder 501 is limited, which avoids the phenomenon that the extraction cylinder 501 deviates from the position when the deodorized liquor distillation tower equipment 1 is running, and the liquor vapor in the tower body 2 is too large from bottom to top, which causes the extraction cylinder 501 to deviate from the position.

[0085] In the embodiment of the present disclosure, the deodorized liquor distillation tower equipment 1 can further include a plurality of lower trays 6 arranged in the tower body 2. The plurality of lower trays 6 are arranged in the axial direction of the tower body 2. The lower trays 6 are located below the upper trays 3 and are arranged in a spaced manner with the upper trays 3. Specifically, the lower trays 6 can be arranged between the upper trays 3 and the second extraction structure 52. At least one of the lower trays 6 is provided with a reaction bag 65, and the reaction bag 65 can be a flavor catalyst bag.

[0086] It should be noted that the wort fed through the feed inlet contains many components (a few hundred to thousands). These components can form a natural and unique flavor during the distillation process. For example, acid and alcohol components can undergo esterification during the distillation process to enhance the flavor of the liquor. Since esterification is a reversible reaction, the present disclosure sets the reaction bag 65 on the lower tray 6 to facilitate the reaction bag 65 to catalyze the reaction rate of acid and alcohol, and at the same time, to break the reversible reaction, so that the esterification reaction of acid and alcohol proceeds in a positive direction. After distillation, the reactants and products that do not react are completely separated, and the desired product is obtained. By setting the reaction bag 65 on the lower tray 6, the liquor on the lower tray 6 can fully contact the reaction bag 65, thereby improving the utilization rate of the reaction bag 65.

[0087] Further, in order to make the vapor-liquid flow and mass transfer performance of the liquor on the lower tray 6 not be affected by the reaction bag 65, the present disclosure can set the lower tray 6 as a combination of trapezoidal guide fixed valve tray and sieve tray, and the sieve tray is provided with a plurality of spaced sieve holes. After the liquor passes through the exhaust holes on the trapezoidal guide fixed valve tray, it is more evenly dispersed through the sieve holes on the sieve tray, which can fully contact the liquor with the reaction bag 65, while avoiding affecting the mass transfer and heat transfer efficiency and separation performance of the vapor-liquid phase liquor on the lower tray 6. The utilization rate of the reaction bag 65 is high, and the vapor phase reaction is sufficient, thereby improving the industrial application prospect of the deodorized liquor distillation tower equipment 1.

[0088] In this disclosure, a receiving tray 61 and a downcomer 62 may also be provided inside the tower body 2. The receiving tray 61 is located at one end of the lower tray 6 and is positioned slightly below the corresponding lower tray 6. The receiving tray 61 extends radially along the tower body 2, and the lower tray 6 can be connected to the inner wall of the tower body 2 through the receiving tray 61. The downcomer 62 and the receiving tray 61 are located at opposite ends of the lower tray 6, with the top of the downcomer 62 connected to the end of the corresponding lower tray 6, and the downcomer 62 extends axially downward along the tower body 2.

[0089] When there are other lower trays 6 below the lower tray 6 corresponding to the downcomer 62, the downcomer 62 extends to the top surface of the lower tray 6 below it. When there are no other lower trays 6 below the lower tray 6 corresponding to the downcomer 62, a liquid seal plate 63 can be installed at the bottom of the downcomer 62. The liquid seal plate 63 extends radially along the column body 2 and is connected to the inner wall of the column body 2 to receive the liquid flowing down from the lowest lower tray 6, preventing the liquid from flowing directly down into the column bottom 53 and causing turbulence.

[0090] In this disclosure, the top surface of the downcomer 62 can be set slightly higher than the top surface of the corresponding lower tray 6. The portion of the downcomer 62 that is higher than the top surface of the corresponding lower tray 6 forms an overflow weir 64 with the lower tray 6, which keeps the liquid collected by the receiving tray 61 on the overflow weir 64, ensuring the gas-liquid phase mass and heat transfer effect on the lower tray 6.

[0091] It should be noted that the liquid receiving tray 61 and downcomer 62 on two adjacent lower trays 6 in this disclosure can be arranged in opposite directions.

[0092] In addition, such as Figure 8 As shown, the receiving tray 61 and the downcomer 62 can also be located at opposite ends of the upper tray 3.

The upper tray 3 can be connected to the inner wall of the column body 2 via the receiving tray 61. The top of the downcomer 62 is connected to the end of the corresponding upper tray 3, and the downcomer 62 extends downward along the axial direction of the column body 2. When there are other upper trays 3 located below the upper tray 3 corresponding to the downcomer 62, the downcomer 62 extends to the top surface of the lower upper tray 3.

[0093] In this disclosure, the top surface of the downcomer 62 can be set slightly higher than the top surface of the corresponding upper tray 3. The part of the downcomer 62 that is higher than the top surface of the corresponding upper tray 3 forms an overflow weir 64 with the upper tray 3, which keeps the liquid collected by the receiving tray 61 on the overflow weir 64, ensuring the gas-liquid phase mass and heat transfer effect on the upper tray 3.

[0094] The de-flavored strong liquor distillation column device 1 can further comprise a second condenser 7, which is located between the upper tray 3 and the lower tray 6, and the liquor vapor on the lower tray 6 can move to the upper tray 3 through the second condenser 7.

For example, the condensation of fusel oil when the liquor contacts the first extraction structure 51 and the blockage of the first extraction structure 51 can be avoided, so as to ensure the smooth progress of the stripping process of the liquor vapor in the first extraction structure 51.

[0096] In the embodiment of the present disclosure, the de-flavored strong liquor distillation column device 1 can comprise a column bottom discharge pipe 81, a gas phase return pipe 82 and a heater 83, the column bottom discharge pipe 81 and the gas phase return pipe 82 are both arranged at the bottom of the column body 2 and both communicate with the inside of the column body 2, the gas phase return pipe 82 is higher than the column bottom discharge pipe 81, and the gas phase return pipe 82 and the column bottom discharge pipe 81 are both connected with the heater 83, part of the liquor in the column bottom discharge pipe 81 is heated by the heater 83 and then returned to the column body 2 through the gas phase return pipe 82, and the liquor vapor passes through the multiple lower trays 6 and upper trays 3 from bottom to top for layer-by-layer purification, so as to obtain liquor products with desired purity and rich in flavor components in spices.

[0097] Specifically, the column still 53 in the present disclosure contains spices, the heater 83 heats the liquor mash mixed with spices in the column still 53 to boiling, so as to mix the flavor components in the spices into the liquor body, and then the liquor body is purified layer by layer through the lower trays 6 and the upper trays 3, so as to finally obtain strong liquor with strong flavor organoleptic sensation in the oral cavity and nasal cavity.

[0098] In order to obtain liquor products with different alcohol degrees, the present disclosure can further comprise a plurality of liquor taking pipes 9 arranged on the column body 2 and spaced along the axial direction of the column body 2. The liquor taking pipes 9 are located between adjacent upper trays 3 and communicate with the inside of the column body 2. Among them, the plurality of liquor taking pipes 9 are arranged from top to bottom, and the alcohol degree becomes lower and lower, and the component flavor becomes more and more intense. The present disclosure can obtain flavor strong liquor with different component compositions and different alcohol degrees according to customer needs by arranging a plurality of liquor taking pipes 9 on the column body 2.

[0099] It is to be noted that the liquor in the present disclosure can be whiskey or the like.
