[0026] Vodka liquid is a kind of high-concentration alcohol alcoholic beverage produced by taking rye, barley, wheat and other cereals as raw materials, which is widely spread all over the world.

[0027] In the related art, the traditional brewing method of vodka liquid needs to use pressure swing rectification tower for rectification, which needs to circulate heating and condense the original liquor, remove part of flavoring substances and harmful substances in the original liquor to form rectified liquid, but the processing process has high energy consumption, complicated operation steps and complex control program, so that the production cost of vodka liquid is high, and the production efficiency is low. Figure 1 It is a process schematic diagram of the vodka production line of the utility model. Figure 2 It is a process schematic diagram of the purification structure of the utility model. Figure 3 It is a device layout diagram of the purification structure of the utility model.

[0028] Referring to Figures 1 to 3 , for the convenience of understanding and description, the state of the vodka production line placed on the working ground is taken as reference, and the up-down direction of the vodka production line is taken as the up-down direction in the following.

[0029] Figure 4 It is a structural schematic diagram of the sieve plate extraction tower of the utility model.

[0030] Referring to Figures 1 to 4 , the application provides a vodka production line, which can process raw materials to form vodka liquid. The vodka production line comprises a saccharification and fermentation structure 100 and a purification structure 200. The saccharification and fermentation structure 100 can gelatinize, saccharify and ferment raw materials in sequence to produce wort. The purification structure 200 is arranged downstream of the saccharification and fermentation structure 100 to purify the wort to form vodka liquid.

[0031] Among them, the purification structure 200 comprises a sieve plate extraction tower 240. The sieve plate extraction tower 240 comprises an extraction shell 241 provided with an extraction cavity 242, a connecting shaft arranged in the extraction cavity 242 and a vibrating sieve plate. The extraction shell 241 is used for containing original liquor. The connecting shaft is connected to the extraction shell 241 in up-down reciprocating mode. The vibrating sieve plate extends horizontally, and the vibrating sieve plate is connected to the connecting shaft. The connecting shaft can drive the vibrating sieve plate to reciprocate in the extraction cavity 242, so as to sieve the original liquor to form extraction liquid.

[0032] In the process of purifying the mash to form the vodka liquid in the purification structure 200. The sieve plate extraction tower 240 can receive the raw liquor, and the vibrating sieve plate can reciprocate up and down to constantly update the phase interface, strengthen the contact between the two phases, and make the solute effectively transfer from one phase to another phase, so that the raw liquor is constantly separated and mixed to form the extraction liquid. The sieve plate extraction tower 240 does not need to heat or cool the raw liquor, and can only purify the vodka liquid from the raw liquor by reciprocating vibration of the vibrating sieve plate, effectively simplifying the operation steps and complexity of the production line, improving the production efficiency, reducing the production energy consumption, and thus reducing the production cost of the vodka production line.

[0033] Referring to Figure 1 In this embodiment, after the grains are treated by cleaning, drying, etc., the raw materials are processed to form the raw materials, which are then input into the saccharifying and fermenting structure 100 to sequentially undergo gelatinization, saccharification, and fermentation treatment to produce the mash and the mash liquid.

[0034] Referring to Figure 1 In this embodiment, the saccharifying and fermenting structure 100 can include a gelatinization device (not shown in the figure), a saccharification device (not shown in the figure), and a fermentation device (not shown in the figure).

[0036] The saccharification device is located downstream of the gelatinization device and is connected to the gelatinization device to receive the gelatinized materials produced by the gelatinization device. Moreover, the saccharification device can convert the gelatinized starch into fermentable sugar under the action of enzymes, so that the gelatinized materials form saccharified materials.

[0037] The fermentation device is located downstream of the saccharification device and is connected to the saccharification device to receive the saccharified materials of the saccharification device. Moreover, the fermentation device can ferment the fermentable sugar to form alcohol and carbon dioxide under the action of yeast, so that the saccharified materials form the mash and the mash liquid. After the fermentation device produces the mash and the mash liquid, it can also separate the mash and the mash liquid, so that the mash liquid enters the subsequent purification structure 200 for purification, thereby producing the vodka liquid.

[0038] In some embodiments, the gelatinization device can be combined with the saccharification device and / or the fermentation device, thereby reducing the floor area of the production line, reducing the production cost, simplifying the operation process, and improving the production efficiency.

[0041] Referring to Figures 2 to 3 In the embodiment, the purification structure 200 can comprise a wort degassing assembly 210. The wort degassing assembly 210 is arranged downstream of the saccharification and fermentation structure 100 and is in communication with the saccharification and fermentation structure 100.

[0047] In other embodiments, the reboiler can be a thermosyphon reboiler, a forced circulation reboiler, a kettle reboiler and the like.

[0048] In some embodiments, the first condensing accessory 214 can include a condenser, a collection tank (not shown in the figure) and a condensing separation structure (not shown in the figure). The input end of the condenser is connected to the degassing tower 211 to be able to receive and condense the steam, thereby forming a condensed liquid. The input end of the collection tank is connected to the output end of the condenser to accommodate the condensed liquid after the condensation of the condenser. The condensing separation structure is connected to the collection tank to output the condensed liquid in the collection tank as wine head, industrial alcohol and light wine, respectively, and the condensing separation structure can also input the light wine back into the degassing tower 211.

[0049] In other embodiments, the condenser can be a shell-and-tube condenser, a bucket condenser.

[0050] In other embodiments, the condensing separation structure can be connected to the liquids at different liquid levels in the collection tank to output the liquids in the buffer tank at different stages and different liquid levels, thereby being able to output the wine head, industrial alcohol and light wine, respectively.

[0052] Referring to Figures 2 to 3 In the present embodiment, the purification structure 200 can further include a concentrated purification assembly 220. The concentrated purification assembly 220 is located downstream of the mash degassing assembly 210 and is in communication with the mash degassing assembly 210. The mash degassing assembly 210 is capable of receiving the thin wine and processing the thin wine to form concentrated liquid and first fusel liquid.

The second condensing accessory 224 is disposed at the top of the concentrated column 222, so as to condense the steam in the concentrated column 222 and separate the concentrated liquid and the first fusel liquid. The second condensing accessory 224 is capable of inputting the first fusel liquid back into the concentrated column 222. The concentrated column 222 is provided with a fusel output port on the side thereof.

[0054] When the waste liquid separation column 221 receives the thin wine from the degassing column 211, the second reboiling accessory 223 is capable of circulating and boiling the thin wine in the waste liquid separation column 221 and separating and discharging the second waste liquid from the thin wine. After the second reboiling accessory 223 inputs the boiled thin wine back into the waste liquid separation column 221, part of the thin wine evaporates to form steam. The steam can be input into the lower part of the concentrated column 222 through the third communication pipe 225.

[0055] When the steam is input to the lower part of the concentration tower 222, the steam moves from the lower part of the concentration tower 222 to the top of the concentration tower 222 and has a heat transfer reaction with the first fusel oil in the concentration tower 222 during the movement to transfer part of the heat to the first fusel oil in the concentration tower 222, thereby improving the energy utilization efficiency.

[0061] In some embodiments, the waste liquid separation tower 221 and the concentration tower 222 can be combined into a concentration separation tower, the second reboiling accessory 223 is arranged at the bottom of the concentration separation tower, and the second condensing accessory 224 is arranged at the top of the concentration separation tower to process the weak wine to form the concentrated liquid.

[0062] Referring to Figures 2 to 3In this embodiment, the purification structure 200 may further include a water washing tower 230. The water washing tower 230 is located downstream of the concentration tower 222 and upstream of the sieve plate extraction tower 240. The water washing tower 230 is connected to the concentration tower 222 to receive the concentrate output from the concentration tower 222 and to process the concentrate into raw wine and a second fusel oil. The water washing tower 230 is also connected to the sieve plate extraction tower 240 to output the raw wine for vibration extraction within the sieve plate extraction tower 240.

[0063] The washing tower 230 may include a washing tower body 231, a third reboiling attachment 232, and a third condensing attachment 233. The washing tower body 231 has a washing space (not shown) for receiving and containing the concentrate. The third reboiling attachment 232 is located at the bottom of the washing tower body 231 and communicates with the washing space. The third reboiling attachment 232 is used to circulate and boil the concentrate and can separate the raw wine. The third condensing attachment 233 is located at the top of the washing tower body 231 and communicates with the washing space. The third condensing attachment 233 is used to condense the steam at the top of the washing space to form a second fusel oil and a washing reflux liquid. The third condensing attachment 233 can return the formed washing reflux liquid to the washing space and can also output the second fusel oil.

[0064] When the concentrate is fed into the water washing tower 230, it is circulated and boiled under the action of the third reboiler attachment 232. After boiling, part of the concentrate evaporates to form steam, which moves from the bottom to the top of the water washing space. Furthermore, during the boiling process, the third reboiler attachment 232 can also separate the raw wine from the concentrate and output it to the sieve plate extraction tower 240, thus facilitating extraction and purification in the sieve plate extraction tower 240.

[0065] The third condenser attachment 233 receives steam from the top of the washing space and condenses the steam to separate the second fusel oil and the washing reflux liquid, thereby separating some flavor and harmful substances from the concentrate. The third condenser attachment 233 can also return the washing reflux liquid to the washing space. Furthermore, the third condenser attachment 233 can output the second fusel oil outside the washing tower 230 for use in the production of by-products, thus improving resource utilization efficiency, diversifying the products produced by the vodka production line, and increasing the economic benefits of the vodka production line.

[0066] In some embodiments, the third reboiling attachment 232 may be described with reference to the first reboiling attachment 213 described above.

[0067] The third reboiling attachment 232 may include a reboiler and a reboiling separation structure, which can return a portion of the concentrated liquid after heating and boiling to the water washing space, separate the original wine from the concentrated liquid, and input the original wine into the sieve plate extraction tower 240 for extraction and purification.

[0068] In some embodiments, the third condensing accessory 233 may be described with reference to the first condensing accessory 214 described above.

[0069] The third condensing accessory 233 may include a condenser, a collection tank, and a condensation separation structure. The condenser is capable of receiving steam in the water washing space and condensing the steam into liquid. The collection tank is used to receive the liquid condensed by the condenser. The condensation separation structure is capable of separating the liquid in the collection tank into the second fusel oil and the water washing reflux liquid. Furthermore, the condensation separation structure can return the water washing reflux liquid to the water washing space and can also output the second fusel oil outside the water washing tower 230.

[0070] See Figures 2 to 4 In this embodiment, the sieve plate extraction tower 240 is located downstream of the water washing tower 230 and is connected to the water washing tower 230 to receive water and the raw wine output from the water washing tower 230. The sieve plate extraction tower 240 can perform liquid-liquid extraction by vibrating and sieving the raw wine, thereby forming extraction waste liquid and extract liquid from the water and the raw wine.

[0071] The sieve plate extraction tower 240 includes an extraction shell 241 with an extraction chamber 242, a connecting shaft disposed within the extraction chamber 242, and a vibrating sieve plate. The extraction shell 241 is used to contain the raw wine. The connecting shaft is reciprocally connected to the extraction shell 241. The vibrating sieve plate extends horizontally and is connected to the connecting shaft. The sieve plate has multiple spaced-apart small holes. The connecting shaft can drive the vibrating sieve plate to vibrate reciprocally within the extraction chamber 242, thereby sieving the raw wine to form an extract.

[0072] The sieve plate extraction tower 240 receives raw spirits. The vibrating sieve plate reciprocates, causing the spirits to separate and mix through small holes, resulting in a lighter extract and a heavier waste extract. Compared to pressure swing distillation towers, this sieve plate extraction tower 240 eliminates the need for heating or cooling the spirits; the reciprocating vibration of the sieve plate alone is sufficient to extract vodka, effectively reducing energy consumption and thus lowering production costs for vodka production lines. Furthermore, the sieve plate extraction tower 240 boasts high mass transfer efficiency. The up-and-down movement of the sieve plate continuously refreshes the phase interface, enhancing contact between the two phases and allowing for more efficient transfer of solute from one phase to another. Additionally, its operating parameters, such as the sieve plate's movement frequency, can be adjusted according to different systems and process requirements.

[0073] See Figures 2 to 4In this embodiment, the sieve plate extraction tower 240 includes multiple vibrating sieve plates. The connecting shaft extends in the vertical direction; the multiple vibrating sieve plates are arranged at intervals in the vertical direction on the connecting shaft. The multiple vibrating sieve plates arranged at intervals in the vertical direction can simultaneously perform multiple vibration sieving of the raw wine, so that the substances in the raw wine can be screened through multiple phase interfaces, thereby improving the purity of the extract at the vibration extraction point.

[0074] See Figure 3 and Figure 4 In this embodiment, the sieve plate extraction tower 240 also includes a drive member 243. The drive member 243 is located outside the extraction housing 241 and is connected to the connecting shaft for driving the connecting shaft to move up and down reciprocally.

[0075] In some embodiments, the connecting shaft extends vertically through the extraction housing 241 and connects to the drive member 243, thereby reciprocating under the action of the drive member 243. In other embodiments, the drive member 243 may be a motor, a cylinder, or a hydraulic cylinder.

[0076] See Figure 4 In this embodiment, the extraction chamber 242 within the extraction housing 241 is divided from top to bottom into an extraction liquid chamber 2421, an extraction working chamber 2422, and an extraction waste liquid chamber 2423. A vibrating screen plate is located within the extraction working chamber 2422 to vibrate and screen the raw wine into a light-phase extraction liquid and a heavy-phase extraction waste liquid. The extraction liquid is discharged upwards from the extraction working chamber 2422 into the extraction liquid chamber 2421, while the extraction waste liquid is discharged downwards from the extraction working chamber 2422 into the extraction waste liquid chamber 2423.

[0077] The light phase extract is separated from the heavy phase extract waste liquid, thereby effectively extracting the original wine, improving the extraction efficiency, and outputting a high-concentration extract to facilitate purification and extraction in subsequent devices within the purification structure 200.

[0078] In some embodiments, in a cross section perpendicular to the vertical direction, the cross-sectional area of ​​the extraction liquid chamber 2421 and the cross-sectional area of ​​the extraction waste liquid chamber 2423 are both greater than the cross-sectional area of ​​the extraction working chamber 2422.

[0079] When the vibrating screen plate vibrates to separate the extract liquid and the extraction waste liquid, the vibrating screen plate provides kinetic energy to the extract liquid, so that the extract liquid flows upward from the extraction working chamber 2422 with a smaller cross-sectional area into the extraction liquid chamber 2421 with a larger cross-sectional area. The liquid in the extraction liquid chamber 2421 can buffer the upward impact kinetic energy of the extract liquid to protect the inner wall of the extraction liquid chamber 2421.

[0080] When the vibrating screen plate vibrates to separate the extract liquid and the extraction waste liquid, the vibrating screen plate provides kinetic energy to the extraction waste liquid, so that the extraction waste liquid flows upward from the extraction working chamber 2422 with a smaller cross-sectional area into the extraction waste liquid chamber 2423 with a larger cross-sectional area. The liquid in the extraction waste liquid chamber 2423 can buffer the downward impact kinetic energy of the extract liquid to protect the inner wall of the extraction waste liquid chamber 2423.

[0081] See Figure 4 In this embodiment, the extraction housing 241 is provided with an extraction water inlet 2411, a raw wine inlet 2412, an extraction waste liquid outlet 2413, and an extraction liquid outlet 2414. The extraction water inlet 2411 is located at the lower part of the extraction housing 241, below the vibrating screen plate, for inputting water into the extraction chamber 242. The raw wine inlet 2412 is located at the upper part of the extraction housing 241, above the vibrating screen plate, for inputting raw wine into the extraction chamber 242. The extraction waste liquid outlet 2413 is located at the lower part of the extraction housing 241, below the extraction water inlet 2411, and is used to output extraction waste liquid to the outside. The extraction liquid outlet 2414 is located at the upper part of the extraction housing 241, above the raw wine inlet 2412, for outputting the extraction liquid.

[0082] When the sieve plate extraction tower 240 is operating, water is introduced into the extraction water inlet 2411 as the heavy liquid, and raw wine is introduced into the raw wine inlet 2412 as the clear liquid. When the water and raw wine mix in the extraction working chamber 2422, the vibrating sieve plate vibrates, causing some flavor and harmful substances in the raw wine to enter the water, forming extraction waste liquid which is output to the extraction waste liquid chamber 2423 and finally discharged to the outside through the extraction waste liquid outlet 2413. The vibration of the vibrating sieve plate also causes some substances in the raw wine to form extract, which is input into the extract liquid chamber 2421 and finally output through the extract liquid outlet 2414 to the subsequent device in the purification structure 200 for purification.

[0083] In some embodiments, the extraction water inlet 2411 and the raw wine inlet 2412 are respectively provided in the extraction working chamber 2422 so that water and raw wine can be mixed and subjected to vibration extraction within the extraction working chamber 2422. The extraction waste liquid outlet 2413 is provided in the extraction waste liquid chamber 2423 so that waste liquid within the extraction waste liquid chamber 2423 can be discharged to the outside. The extract liquid outlet 2414 is provided in the extraction liquid working chamber so that the extract liquid can be discharged to the sieve plate extraction tower 240.

[0084] See Figures 2 to 3 In this embodiment, the purification structure 200 further includes a methanol removal tower 250. The methanol removal tower 250 is located downstream of the sieve plate extraction tower 240. The methanol removal tower 250 can receive the extract formed by the sieve plate extraction tower 240 and remove methanol from the extract to form vodka.

[0085] The methanol removal tower 250 may include a removal tower body 251, a fourth reboiling attachment 252, and a fourth condensing attachment 253. The removal tower body 251 is connected to a sieve plate extraction tower 240 via an extract outlet 2414, and has a removal space within it for receiving and containing the extract. The fourth reboiling attachment 252 is located at the bottom of the removal tower body 251 and is connected to the removal space. The fourth reboiling attachment 252 is used to boil the extract and can output vodka. The fourth condensing attachment 253 is located at the top of the removal tower body 251 and is connected to the removal space. The fourth condensing attachment 253 is used to condense the vapor at the top of the removal space to form vodka reflux and industrial alcohol. The fourth condensing attachment 253 can return the formed vodka reflux to the removal space and can also output the industrial alcohol.

[0086] When the extract is fed into the methanol removal tower 250, it is circulated and boiled by the fourth reboiler attachment 252. After boiling, part of the extract evaporates to form steam, which moves from the bottom to the top of the removal space. Furthermore, while boiling the extract, the fourth reboiler attachment 252 can also separate vodka from the extract and discharge it outside the methanol removal tower 250, facilitating subsequent blending of the vodka.

[0087] The fourth condenser attachment 253 receives steam from the top of the degassing space, and condenses the steam to separate industrial alcohol and vodka reflux. The separated industrial alcohol contains some flavor compounds and harmful substances from the extract. The fourth condenser attachment 253 can return the vodka reflux to the degassing space and also output the separated industrial alcohol to the methanol removal tower 250, thereby diversifying the products produced by the vodka production line, improving resource utilization efficiency, and increasing the economic benefits of the vodka production line.

[0088] In some embodiments, the vodka liquid separated by the fourth reboiling attachment 252 has an alcohol concentration of ≥96.4% to facilitate subsequent blending.

[0089] In some embodiments, the fourth reboiling attachment 252 may be described with reference to the first reboiling attachment 213 described above.

[0090] The fourth reboiling attachment 252 may include a reboiler and a reboiling separation structure, which can return a portion of the extracted liquid after heating and boiling to the removal space, and can also separate vodka with an alcohol concentration of ≥96.4%, so that the vodka can be output to the methanol removal tower 250, thereby facilitating the subsequent blending and use of the vodka.

[0091] In some embodiments, the fourth condensing accessory 253 may be described with reference to the first condensing accessory 214 described above.

[0092] The fourth condensing accessory 253 may include a condenser, a collection tank, and a condensation separation structure. The condenser is capable of receiving vapor in the removal space and condensing the vapor into liquid. The collection tank is used to receive the liquid condensed by the condenser. The condensation separation structure is capable of separating industrial alcohol and vodka reflux from the liquid in the collection tank, and can return the vodka reflux to the removal space, and can also output the industrial alcohol outside the methanol removal tower 250.

[0093] See Figures 2 to 3 In this embodiment, the purification structure 200 further includes a fusel oil tower 260. The fusel oil tower 260 is connected to both the concentration tower 222 and the water washing tower 230 to receive the first fusel oil and the second fusel oil. The fusel oil tower 260 can process the first fusel oil and the second fusel oil into industrial alcohol and heads.

[0094] The fusel oil tower 260 may include a fusel oil tower body 261, a fifth reboiling attachment 262, and a fifth condensing attachment 263. The fusel oil tower body 261 is connected to the third condensing attachment 233 of the concentration tower 222 and the water washing tower 230, respectively. The fusel oil tower body 261 is used to contain the fusel oil resulting from the mixture of the first and second fusel oils. The fusel oil tower body 261 has a fusel oil space for receiving and containing the fusel oil liquid. The fifth reboiling attachment 262 is located at the bottom of the fusel oil tower body 261 and is connected to the fusel oil space. The fifth reboiling attachment 262 is used to boil the fusel oil liquid and can output a third waste liquid. The fifth condensing attachment 263 is located at the top of the fusel oil tower body 261 and is connected to the fusel oil space. The fifth condenser attachment 263 is used to condense the vapor at the top of the fusel oil space to form fusel oil reflux liquid, heads and industrial alcohol. The fifth condenser attachment 263 can return the formed fusel oil reflux liquid to the fusel oil space, and can also output the industrial alcohol and heads.

[0095] When the fusel oil solution is fed into the fusel oil tower 260, it is circulated and boiled under the action of the fifth reboiling attachment 262. After boiling, part of the fusel oil solution evaporates to form steam, which moves from the bottom to the top of the fusel oil space. Furthermore, during the boiling process, the fifth reboiling attachment 262 can also separate a third waste liquid from the fusel oil solution and discharge it outside the fusel oil tower 260.

[0096] The fifth condenser attachment 263 receives steam from the top of the fusel oil space and condenses the steam to separate industrial alcohol, heads, and fusel oil reflux. The fifth condenser attachment 263 can return the fusel oil reflux to the fusel oil space and also output the separated heads and industrial alcohol to the outside of the fusel oil tower 260, thereby diversifying the products produced by the vodka production line, improving resource utilization efficiency, and increasing the economic benefits of the vodka production line.

[0097] In some embodiments, the fifth reboiling attachment 262 may be described with reference to the first reboiling attachment 213 described above.

[0098] The fifth reboiling attachment 262 may include a reboiler and a reboiling separation structure, which can return a portion of the heated and boiled fusel oil to the fusel oil space, and can also separate a third waste liquid, which can be discharged to the outside of the fusel oil tower 260.

[0099] In some embodiments, the fifth condensing accessory 263 may be described with reference to the first condensing accessory 214 described above.

[0100] The fifth condensing accessory 263 may include a condenser, a collection tank, and a condensation separation structure. The condenser is capable of receiving vapor from the fusel oil space and condensing the vapor into liquid. The collection tank is used to receive the liquid condensed by the condenser. The condensation separation structure is capable of separating the liquid in the collection tank into heads, industrial alcohol, and fusel oil reflux, and can return the fusel oil reflux to the fusel oil space, and can also output the heads and industrial alcohol outside the fusel oil tower 260.

[0101] See Figures 2 to 3 In this embodiment, the purification structure 200 also includes a head column 270. The head column 270 is connected to the fusel oil column 260 and the mash degassing component 210. The head column 270 receives the heads and processes them into industrial alcohol and circulating water, thus realizing multi-level utilization and reuse of resources.

[0102] The head column 270 may include a head column body 271, a sixth reboiler attachment 272, and a sixth condenser attachment 273. The head column body 271 is connected to the first condenser attachment 214 and the fifth condenser attachment 263, and has a head space for receiving and containing the heads. The sixth reboiler attachment 272 is located at the bottom of the head column body 271 and is connected to the head space. The sixth reboiler attachment 272 is used to boil the heads and can output circulating water. The sixth condenser attachment 273 is located at the top of the head column body 271 and is connected to the head space. The sixth condenser attachment 273 is used to condense the vapor at the top of the head space to form head reflux liquid and industrial alcohol. The sixth condenser attachment 273 can cause the formed head reflux liquid to flow back into the head space and can also output industrial alcohol.

[0103] After the distillate heads are fed into the headstock column 270, they are circulated and boiled under the action of the sixth reboiler attachment 272. After boiling, some of the headstock heads evaporate to form steam, which moves from the bottom to the top of the headstock space. Furthermore, during the boiling process, the sixth reboiler attachment 272 can also separate circulating water from the headstock heads and output it outside the headstock column 270, thus achieving multi-stage utilization of resources and heat.

[0104] The sixth condenser attachment 273 receives steam from the top of the head space and condenses the steam to separate industrial alcohol and head reflux liquid. The sixth condenser attachment 273 can return the head reflux liquid to the head space and also output the separated industrial alcohol outside the head tower 270, thereby diversifying the products produced in the vodka production line, improving resource utilization efficiency, and increasing the economic benefits of the vodka production line.

[0105] In some embodiments, the sixth reboiling attachment 272 may be described with reference to the first reboiling attachment 213 described above.

[0106] The sixth reboiler attachment 272 may include a reboiler and a reboiler separation structure, which can return a portion of the heated and boiled head to the head space, and can also separate circulating water so that the circulating water can be output outside the head tower 270, thereby facilitating the recycling of water resources and heat.

[0107] In other embodiments, the sixth reboil attachment 272 can be connected to the water washing tower 231 to assist in the separation of the concentrate in the water washing tower 230 to form the second fusel oil and raw wine, thereby improving the recycling efficiency of resources and reducing the production cost of the production line.

[0108] In some embodiments, the sixth condensing accessory 273 may be described with reference to the first condensing accessory 214 described above.

[0109] The sixth condensing accessory 273 may include a condenser, a collection tank, and a condensation separation structure. The condenser is capable of receiving vapor in the head space and condensing the vapor into liquid. The collection tank is used to receive the liquid condensed by the condenser. The condensation separation structure is capable of separating industrial alcohol and head reflux liquid from the liquid in the collection tank, and can return the head reflux liquid to the head space, and can also output the industrial alcohol outside the head column 270.

[0110] In this embodiment, the materials of the mash tower 212, degassing tower 211, waste liquid separation tower 221, concentration tower 222, water washing tower 230, sieve plate extraction tower 240, methanol removal tower 250, fusel oil tower 260, and / or head tower 270 are all made of copper. The copper material can displace methyl sulfides in the liquid during the purification of the mash in the purification structure 200 to produce vodka, thereby improving the taste of the vodka.

[0111] See Figures 1 to 4 The process of using the vodka production line in this application is as follows: Workers first process the grains by washing and drying to form raw materials, which are then transported to the saccharification and fermentation structure 100. After gelatinization, saccharification, and fermentation, mash and malt liquid are formed. The saccharification and fermentation structure 100 then separates the mash and malt liquid, and the malt liquid is input into the purification structure 200.

[0112] After the mash is purified by the mash degassing component 210, the first waste liquid, industrial alcohol, distillate heads and light liquor can be separated. The first waste liquid and industrial alcohol can be discharged outside the mash degassing component 210, the distillate heads can be fed into the distillate head tower 270, and the light liquor can be fed into the concentration and purification component 220.

[0113] After receiving the diluted wine, the concentration and purification unit 220 purifies the diluted wine to separate the second waste liquid, the first fusel oil and the concentrate. The second waste liquid is discharged outside the concentration and purification unit 220, the first fusel oil is fed into the fusel oil tower 260 and the concentrate is fed into the water washing tower 230.

[0114] After receiving the concentrate in the water washing tower 230, the concentrate is mixed with circulating water in the water washing tower body 231, and the second fusel oil and raw wine are purified and separated. The second fusel oil can be fed into the fusel oil tower 260, and the raw wine can be fed into the sieve plate extraction tower 240.

[0115] The sieve plate extraction tower 240 feeds raw liquor into the extraction chamber 2421 through the raw liquor inlet 2412. After entering the extraction chamber 2421, the raw liquor mixes with water fed into the extraction water inlet 2411, and is separated by multiple sieve plates to form a light-phase extract and a heavy-phase extraction waste liquid. The extract is discharged into the methanol removal tower 250 through the extract outlet 2414, and the extraction waste liquid is discharged to the outside through the extraction waste liquid outlet 2413.

[0116] After receiving the extract, the methanol removal tower 250 removes methanol from the extract to form industrial alcohol and vodka. The vodka is then exported for blending and use. The industrial alcohol is exported to improve the by-products of the vodka production line and enhance the multi-level utilization efficiency of resources.

[0117] After receiving the first fusel oil and the second fusel oil, the fusel oil tower 260 purifies the fusel oil to separate the heads, industrial alcohol and the third waste liquid. The heads can be fed into the heads tower 270, and the industrial alcohol and the third waste liquid can be discharged out of the fusel oil tower 260.

[0118] After receiving the heads from the mash degassing unit 210 and the fusel oil tower 260, the head of the distillate tower 270 is processed and separated into industrial alcohol and circulating water by boiling and condensation. The industrial alcohol is then output to the outside of the head of the distillate tower 270, and the circulating water is output to the outside of the head of the distillate tower 270 or to the water washing tower 230.

[0119] This vodka production line can extract the original spirit from the base spirit using a 240-inch sieve plate extraction tower. It eliminates the need for heating or cooling the base spirit; the extract is extracted solely through the reciprocating vibration of the vibrating sieve plates. This effectively simplifies the operation and reduces the complexity of the production line, improving efficiency and reducing energy consumption, thereby lowering the production cost. Furthermore, the production process also produces and separates various byproduct industrial alcohols, enabling multi-level resource utilization and further reducing production costs.

[0120] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
