Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to a spirits preparation system. Background Technology

[0002] Spirits, generally speaking, refer to high-purity liquors with an alcohol content of 40% or higher. The history of spirits can be traced back to centuries ago, and they are made from grains such as rye, barley, and wheat through fermentation and distillation techniques.

[0003] In existing spirits production systems, the raw materials are first crushed, cooked, saccharified, and fermented to produce mash. The mash is then fed into a nine-tower structure for distillation to produce spirits.

[0004] However, this spirits preparation system requires a lot of production equipment, including mash production components and nine-tower components. These production equipment occupies a large space, which makes the production cost of spirits high. Utility Model Content

[0005] The purpose of this application is to provide a spirits preparation system with fewer equipment, smaller production equipment footprint, and lower production costs.

[0008] In some embodiments, the other buffer vapors after condensation in the second distillation column are second vapors; the distillation assembly further includes a third distillation column located downstream of the second distillation column, the third distillation column being able to receive the second vapors and partially condense the second vapors to form a second reflux liquid; the third distillation column being able to input the second reflux liquid into the second distillation column.

[0009] In some embodiments, the remaining second vapor after condensation in the third distillation column is the third vapor; the distillation assembly further includes a product condensation device, which is capable of receiving the third vapor, condensing the third vapor into a liquid reaching a preset alcohol concentration, and outputting it outside the product condensation device to form a second spirit.

[0010] In some embodiments, the product condensation device can also be connected to the buffer tank to input the liquid that has not reached the preset alcohol concentration after the third steam is condensed into the buffer tank.

[0011] In some embodiments, the condensation structure in the first distillation column, the second distillation column, the third distillation column, and / or the product condensation equipment is a shell-and-tube heat exchanger.

[0025] Figure 1 This is a schematic diagram of the process of the spirit preparation system of this utility model. Figure 2 This is a schematic diagram of the structure of the spirit preparation system of this utility model.

[0026] See Figure 1 and Figure 2 For ease of understanding and description, the state of the spirit preparation system placed on the working ground is used as a reference, and the vertical direction of the spirit preparation system is used as the vertical direction in the following text.

[0027] See Figure 1 and Figure 2This application provides a spirits production system for processing grains to produce spirits. The spirits production system (hereinafter referred to as the production system) includes a mash production component 100 and a distillation component 200. The mash production component 100 removes the germ from the grains to form raw materials, and sequentially gelatinizes, saccharifies, and ferments the raw materials to form mash. The distillation component 200 includes a first distillation column 210, a buffer tank 220, and a second distillation column 230. The first distillation column 210 is located downstream of the mash production component 100. The first distillation column 210 receives the mash and distills it to form a bulk liquid. The buffer tank 220 is located downstream of the first distillation column 210. The buffer tank 220 includes a tank body 221 and a heating structure. The tank body 221 is connected to the first distillation column 210 to receive the bulk liquid. The heating structure heats and boils the liquid in the tank body 221 to form buffer vapor. The second distillation column 230 is located downstream of the buffer tank 220. The second distillation column 230 can receive the buffer vapor from the buffer tank 220 and partially condense the buffer vapor to form the first reflux liquid. The second distillation column 230 can also feed the first reflux liquid into the buffer tank 220, and the buffer tank 220 can mix the original liquid and the first reflux liquid to produce the first spirit.

[0028] When the spirits production system produces spirits, grains are placed into the mash production unit 100. The mash production unit 100 first removes the germ from the grains to form raw materials. The raw materials then undergo gelatinization, saccharification, and fermentation processes to form mash.

[0029] The first distillation column 210 is connected to the mash production unit 100 to receive the mash. After receiving the mash, the first distillation column 210 distills the mash to form a raw liquid, which can be fed into the feed buffer tank 220.

[0030] After the raw liquid enters tank 221, the heating structure heats and boils the liquid inside tank 221 to form buffer vapor. The buffer vapor can then enter the second distillation column 230.

[0031] After receiving the buffer vapor, the second distillation column 230 can condense a portion of the buffer vapor to form the first reflux liquid. The first reflux liquid is fed into the buffer tank 220 and mixed with the original liquid to produce the first spirit. This spirit production system can produce spirit using only the first distillation column, buffer tank, and second distillation column, thereby effectively reducing the number of spirit production units and the floor space required, as well as reducing the number of production steps and processes, thus effectively lowering the production cost of spirit.

[0032] See Figure 1 and Figure 2In this embodiment, the mash production component 100 can be a grain washing machine (not shown in the figure). The grain washing machine can wash and dry the grain, thereby ensuring the cleanliness of the grain and facilitating subsequent processing of the grain to produce mash.

[0033] The structure of the grain washing machine can refer to the structure of existing grain processing equipment to ensure that it can clean and dry the grain and guarantee its quality.

[0034] In some embodiments, grains may include corn, wheat, barley, rye, etc.

[0035] See Figure 1 and Figure 2 In this embodiment, the mash production assembly 100 may further include a degerming machine (not shown in the figure). The degerming machine is located downstream of the grain washing machine to receive washed and dried grain. The degerming machine removes the germ from the grain, leaving the remaining endosperm, aleurone layer, etc., as raw materials. Removing the germ from the grain effectively reduces the oil content of the mash produced after processing, thereby reducing the oil content of the spirit produced by the distillation assembly 200, reducing the greasiness of the spirit, enhancing its taste, and improving its transparency and purity. Furthermore, reducing the oil content at the source of spirit production avoids defatting operations after production, reducing processing steps, saving energy consumption for heating and cooling during defatting, and reducing the need for defatting towers, reboiler structures, condenser structures, reflux pumps, and other components, thus lowering the production cost and improving the production efficiency of the spirit.

[0036] The structure of the degerm remover can refer to the structure of existing degerm removers, as long as it can remove the germ from the grain.

[0037] In this embodiment, the mash production assembly 100 may further 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).

[0038] The gelatinization unit is located downstream of the degerminator to receive raw materials. The gelatinization unit expands and dissolves the starch in the raw materials under heating conditions to form a gelatinized material, thus facilitating subsequent saccharification and fermentation.

[0039] The saccharification unit is located downstream of the gelatinization unit and is connected to it to receive the gelatinized material produced by the gelatinization unit. Furthermore, the saccharification unit, under the action of enzymes, converts the gelatinized starch into fermentable sugars, thus transforming the gelatinized material into saccharified material.

[0040] The fermentation unit is located downstream of the saccharification unit and is connected to it to receive the saccharified material. The fermentation unit, under the action of yeast, ferments fermentable sugars to produce alcohol and carbon dioxide, thereby forming mash and malt liquor from the saccharified material. After producing mash and malt liquor, the fermentation unit can separate them, allowing the malt liquor to enter the subsequent distillation unit 200 for distillation, thus producing spirits.

[0041] In some embodiments, any of the grain washing machine, degerming machine, gelatinization device, saccharification device, and fermentation device can be combined to reduce the floor space of the preparation system, lower production costs, simplify the operation process, and improve production efficiency.

[0042] See Figure 1 and Figure 2 In this embodiment, the preparation system also includes a distillation unit 200. The distillation unit 200 is located downstream of the fermentation apparatus to receive the mash produced by the fermentation apparatus. The distillation unit 200 can process the mash to produce the first spirit with reduced processing equipment, thereby effectively reducing the floor space required for the preparation system, improving the production efficiency of the spirit, and lowering the production cost of the spirit.

[0043] See Figure 1 and Figure 2 In this embodiment, the distillation assembly 200 includes a first distillation column 210. The first distillation column 210 is connected to the fermentation apparatus to receive the mash. The first distillation column 210 may include a first column body 211, a reboiler 212, and a first condenser 213. The first column body 211 is used to contain the raw liquid. The reboiler 212 is disposed at the bottom of the first column body 211 to heat and boil a portion of the raw liquid to generate first steam. The first condenser 213 is disposed at the top of the first column body 211 to condense a portion of the first steam to generate condensate, which flows into the first column body 211 and is then fed into a buffer tank 220.

[0044] After the mash enters the chamber within the first tower body 211, it flows to the bottom of the first tower body 211 under the influence of gravity. The reboiling device 212 heats and boils the liquid in the first tower body 211, causing the liquid to form first steam. The first steam flows from bottom to top within the first tower body 211 and reaches the first condenser 213. The first condenser 213 condenses a portion of the first steam, forming condensate which flows back to the bottom of the first tower body 211. The remaining portion of the first steam passes through the first condenser 213 as gas and is discharged to the outside, thereby effectively removing strong flavor substances and harmful substances from the mash, thus ensuring the safety of subsequent spirits products.

[0045] See Figure 1 and Figure 2In this embodiment, a mash inlet is provided on the periphery of the first tower body 211. The mash inlet is located above the reboiling device 212, so that the mash can flow to the reboiling device 212 under gravity, thereby facilitating the boiling of the mash by the reboiling device 212. Furthermore, when the reboiling device 212 boils the mash, the first steam flows upward to contact the downward-moving mash and condensate, thereby causing a heat transfer reaction to transfer some heat to the mash and condensate, improving energy utilization efficiency.

[0046] The refluxed condensate and part of the mash in the first tower body 211 can mix to form the raw liquid. The raw liquid outlet is also provided on the periphery of the first tower body 211. The raw liquid outlet is located between the mash inlet and the reboiler 212. The raw liquid outlet is connected to the buffer tank 220 to output the raw liquid into the buffer tank 220.

[0047] The top of the first tower body 211 is provided with an exhaust outlet to discharge the exhaust gas after it has been condensed by the first condenser 213, thereby effectively removing strong flavor substances and harmful substances from the mash and ensuring the safety of subsequent spirit products.

[0048] See Figure 1 and Figure 2 In this embodiment, the reboiling device 212 may include a reboiler and a reboiling separation structure (not shown in the figure). The reboiler is connected to the bottom of the first tower body 211 to boil the mash and form a vapor-liquid mixture. The reboiling separation structure connects the reboiler and the first tower body 211 to input the vapor-liquid mixture into the first tower body 211. The reboiling separation structure is also capable of separating a first waste liquid, composed of some flavor substances and harmful substances, from the vapor-liquid mixture and discharging the first waste liquid to the outside.

[0049] In other embodiments, the reboiler can be a thermosiphon reboiler, a forced circulation reboiler, a kettle reboiler, or the like.

[0050] See Figure 1 and Figure 2 In this embodiment, the first condenser 213 can be a shell-and-tube condenser. The first condenser 213 is located within the chamber of the first tower body 211 and at the top of the chamber. The first condenser 213 includes a shell and condenser tubes passing through the shell. The shell extends horizontally to seal against the inner peripheral wall of the first tower body 211. The condenser tubes extend vertically to pass through the shell. A refrigerant chamber is formed between the condenser tubes and the shell to allow refrigerant flow and to cool the first vapor.

[0051] When the first condenser 213 is working, the first steam flows upward from the bottom of the first tower body 211 and into the condenser tube. The refrigerant flows through the refrigerant chamber to exchange heat with the first steam in the condenser tube, thereby causing part of the first steam to condense into condensate. The condensate flows back to the bottom of the first tower body 211 through the condenser tube; the other part of the first steam passes through the condenser tube to form waste gas, which is discharged to the outside through the waste gas outlet.

[0052] See Figure 1 and Figure 2 In this embodiment, the distillation assembly 200 further includes a buffer tank 220. The buffer tank 220 includes a tank body 221 and a heating structure. The tank body 221 is connected to the raw liquid outlet of the first column 211 to receive the raw liquid. The heating structure can heat the raw liquid in the tank body 221 to form buffer vapor, and the buffer vapor in the tank body 221 can be fed into the second distillation column 230 for distillation.

[0053] See Figure 1 and Figure 2 In this embodiment, the tank body 221 has a raw liquid inlet on its periphery, which is connected to the raw liquid outlet of the first tower body 211, so as to facilitate the raw liquid in the first tower body 211 to enter the tank body 221.

[0054] The top of the tank 221 is provided with a buffer steam outlet so that the buffer steam can be fed into the second distillation column 230 through the buffer steam outlet.

[0055] The tank body 221 is also provided with a first reflux inlet on its periphery. The first reflux inlet is used to connect with the second distillation column 230 so that the first reflux liquid in the second distillation column 230 can flow back to the buffer tank 220 through the first reflux inlet.

[0056] The original liquid and the first reflux liquid in tank 221 can be mixed to form the first spirit. The bottom of tank 221 has a first spirit outlet for discharging the first spirit mixed in tank 221.

[0057] In some embodiments, the raw liquid inlet is located above the first reflux inlet so that the first reflux inlet is close to the first spirit outlet, thereby facilitating the output of the first spirit and ensuring the alcohol concentration of the first spirit.

[0058] See Figure 1 and Figure 2 In this embodiment, other inlets may be provided on the periphery of the tank 221. These other inlets may be connected to an external water source to allow water to be introduced into the tank 221 to dilute the liquid in the buffer tank 220.

[0059] In some embodiments, other feed ports may be connected to other raw material production equipment or other raw material storage equipment. When the total amount of raw material in tank 221 does not reach the required amount to be input into the second distillation column 230, in order to ensure the continuity of production of the preparation system, it is necessary to feed raw material into tank 221 through other feed ports so that the total amount of liquid in tank 221 remains at the preset amount, thereby meeting the requirements for stable and safe operation of the preparation system and improving the reliability and safety of the preparation system.

[0060] See Figure 1 and Figure 2 In this embodiment, a second reflux inlet may be provided on the periphery of the tank body 221. The second reflux inlet is used to connect with other structures within the distillation assembly 200.

[0061] In some embodiments, the first spirit may be whiskey with an alcohol content of 40%-68%.

[0062] See Figure 1 and Figure 2 In this embodiment, the heating structure can be a jacket. The jacket is fitted around the outer periphery of the tank 221 to heat and boil the liquid inside the tank 221. A jacket space may be provided inside the jacket, and the jacket space is arranged around the outer periphery of the tank 221. The jacket space is used to contain the heat transfer medium, thereby facilitating the transfer of heat from the heat transfer medium to the tank 221 to heat the liquid inside the tank 221.

[0063] In some embodiments, the jacket has a jacket inlet at the top and a jacket outlet at the bottom. The heat transfer medium enters the jacket space through the jacket inlet at the top and exits to the outside through the bottom of the jacket space, thereby allowing the heat transfer medium to fully interact with the liquid in the tank 221 during its movement from top to bottom, improving the evaporation efficiency in the tank 221 and increasing energy utilization efficiency.

[0064] In some embodiments, the heat transfer medium input through the jacket inlet can be steam. After sufficient heat exchange between the steam and the liquid in the tank 221, the steam condenses to form condensate. The condensate is output through the jacket outlet, thereby improving the heat transfer efficiency of the buffer tank 220, improving the energy utilization efficiency of the buffer tank 220, and reducing the production cost of the buffer tank 220.

[0065] See Figure 1 and Figure 2In this embodiment, the distillation assembly 200 includes a second distillation column 230. The second distillation column 230 includes a second column body 231 and a second condenser 232. The second column body 231 extends vertically. The second column body 231 is used to contain buffer vapor input from the buffer tank 220. The second condenser 232 is disposed at the upper part of the second column body 231 to condense a portion of the buffer vapor within the second column body 231. A portion of the buffer vapor is condensed by the second condenser 232 to form a first reflux liquid, which flows from the upper part of the second column body 231 to the bottom of the second column body 231; the remaining portion of the buffer vapor becomes second vapor after passing through the second condenser 232, and the second vapor can be output from the second column body 231 for subsequent processing by the distillation assembly 200.

[0066] See Figure 1 and Figure 2 In this embodiment, the second distillation column 230 and the buffer tank 220 are connected by the first gas phase pipe 261 and the first liquid phase pipe 264, so as to facilitate the repeated distillation of the liquid in the distillation component 200, thereby making the alcohol concentration of the liquid in the buffer tank 220 reach more than 40% to form the first spirit.

[0067] One end of the first vapor phase pipe 261 is connected to the buffer vapor outlet of the tank 221, and the other end of the first vapor phase pipe 261 is connected to the peripheral wall of the second column 231. The buffer vapor in the buffer tank 220 can enter the second distillation column 230 through the first vapor phase pipe 261.

[0068] One end of the first liquid phase pipe 264 can be connected to the bottom of the second column body 231, and the other end of the first liquid phase pipe 264 can be connected to the first reflux inlet on the tank body 221, so that the first reflux liquid in the second distillation column 230 can be refluxed back to the tank body 221 through the first liquid phase pipe 264.

[0069] See Figure 1 and Figure 2 In this embodiment, the second condenser 232 can be a shell-and-tube heat exchanger.

[0070] The structure of the second condenser 232 can refer to the structure of the first condenser 213 described above, so that the second condenser 232 can condense and buffer steam, and finally form the first reflux liquid and the second steam.

[0071] See Figure 1 and Figure 2 In this embodiment, the distillation assembly 200 may further include a third distillation column 240. The third distillation column 240 is located downstream of the second distillation column 230. The third distillation column 240 is capable of receiving the second vapor and partially condensing the second vapor to form a second reflux liquid. The third distillation column 240 is capable of feeding the second reflux liquid into the second distillation column 230.

[0072] The third distillation column 240 includes a third column body 241 and a third condenser 242. The third column body 241 extends vertically. The third column body 241 is used to contain the second vapor input from the second column body 231. The third condenser 242 is disposed at the upper part of the third column body 241 to condense a portion of the second vapor within the third column body 241. A portion of the second vapor is condensed by the third condenser 242 to form a second reflux liquid, which flows from the upper part of the third column body 241 to the bottom of the third column body 241. The remaining portion of the second vapor becomes third vapor after passing through the third condenser 242, and the third vapor can be discharged from the third column body 241 for subsequent processing by the distillation assembly 200.

[0073] See Figure 1 and Figure 2 In this embodiment, the third distillation column 240 and the second distillation column 230 are connected by a second gas phase pipe 262 and a second liquid phase pipe 265, so as to facilitate repeated distillation of the liquid in the distillation component 200, thereby making the alcohol concentration of the liquid in the buffer tank 220 reach more than 40% to form the first spirit.

[0074] One end of the second vapor phase pipe 262 is connected to the top of the second column body 231, and the other end of the second vapor phase pipe 262 is connected to the peripheral wall of the third column body 241. The second vapor in the second column body 231 can enter the third distillation column 240 through the second vapor phase pipe 262.

[0075] One end of the second liquid phase pipe 265 can be connected to the bottom of the third column body 241, and the other end of the second liquid phase pipe 265 can be connected to the peripheral wall of the second column body 231, so that the second reflux liquid in the third distillation column 240 can be refluxed back into the second column body 231 through the second liquid phase pipe 265.

[0076] When the buffer tank 220 heats the raw liquid, part of the raw liquid evaporates to form buffer vapor. The buffer vapor enters the second tower body 231 through the first vapor phase pipe 261. After entering the second tower body 231, the buffer vapor moves upward and flows in the second condenser 232, so that part of the buffer vapor condenses to form the first reflux liquid, and the other part forms the second vapor.

[0077] The second steam enters the third tower body 241 through the second vapor phase pipe 262 and moves upward within the third tower body 241. When the second steam flows through the third condenser 242, part of the second steam condenses to form the second reflux liquid, and the other part forms the third steam.

[0078] The second reflux liquid flows back to the second tower body 231 through the second liquid phase pipe 265. After mixing with the first reflux liquid, the second reflux liquid flows back to the tank body 221 through the first liquid phase pipe 264. When the alcohol concentration of the liquid in the buffer tank 220 reaches the preset alcohol concentration, the second reflux liquid, the first reflux liquid, and the mash can be mixed to form the first spirit, which is then output.

[0079] When the alcohol concentration of the liquid in the buffer tank 220 does not reach the preset alcohol concentration, the liquid can be circulated and distilled between the buffer tank 220, the second tower 231, and the third tower 241, thereby effectively increasing the alcohol concentration in the buffer tank 220, so that the buffer tank 220 can stably and reliably output the first spirit.

[0080] In some embodiments, one end of the second vapor phase pipe 262 that connects to the third tower body 241 is located at the bottom of the third tower body 241, so that the second vapor and the second reflux liquid can undergo a heat transfer reaction to transfer some of the heat to the second reflux liquid, thereby improving energy utilization efficiency.

[0081] In some embodiments, one end of the second liquid phase pipe 265 that connects to the second tower body 231 is located at the upper part of the second tower body 231 and at the lower side of the condenser, so that the second reflux liquid can flow from the upper part of the second tower body 231 to the bottom of the second tower body 231, thereby facilitating the heat transfer reaction between the second reflux liquid and the buffer steam, so as to transfer some heat to the second reflux liquid and improve energy utilization efficiency.

[0082] See Figure 1 and Figure 2 In this embodiment, the third condenser 242 can be a shell-and-tube heat exchanger.

[0083] The structure of the second condenser 232 can refer to the structure of the first condenser 213 described above, so that the second condenser 232 can condense and buffer steam, and finally form the first reflux liquid and the second steam.

[0084] See Figure 1 and Figure 2 In this embodiment, a separation device (not shown in the figure) is provided at the bottom of the third distillation column 240. The separation device is used to connect the third distillation column 240 and the second distillation column 230, and can separate impurities in the second reflux liquid. After the impurities in the second reflux liquid are separated, a second waste liquid is formed. The separation device can also discharge the second waste liquid to the outside to remove strong flavor substances and harmful substances from the second reflux liquid, thereby ensuring the safety of subsequent spirits products.

[0085] In some embodiments, the separation device is disposed on the second liquid phase tube 265 to separate some flavor substances and harmful substances from the second reflux liquid.

[0086] In other embodiments, the separation device may also be provided on the second liquid phase pipe 265 to separate some flavor substances and harmful substances from the first reflux liquid output from the second tower 231.

[0087] In other embodiments, the separation device may be provided only on the second liquid phase tube 265 or the first liquid phase tube 264.

[0088] See Figure 1 and Figure 2 In this embodiment, the distillation unit 200 further includes a product condenser 250. The product condenser 250 is capable of receiving a third vapor, condensing the third vapor into a liquid reaching a preset alcohol concentration, and outputting it outside the product condenser 250 to form a second spirit.

[0089] The product condensation device 250 includes a tank and a condensation structure disposed within the tank. A collection space is provided within the tank to collect the product condensate after condensation by the condensation structure. The condensation structure is located within the tank and communicates with the third tower 241 to condense the third vapor.

[0090] In some embodiments, the condensation structure in the first distillation column 210, the second distillation column 230, the third distillation column 240 and / or the product condensation device 250 is a shell-and-tube heat exchanger.

[0091] The condensation structure of the product condensing device 250 is a shell-and-tube heat exchanger. The structure of the product condensing device 250 can refer to the structure of the first condenser 213 mentioned above, as long as it can cool the vapor in the condensing tubes to form product condensate.

[0092] A third vapor phase pipe 263 is installed between the product condenser 250 and the third tower 241. One end of the third vapor phase pipe 263 is connected to the top of the third tower 241, and the other end of the third vapor phase pipe 263 passes through the tank and is connected to the condensation structure. The third vapor enters the condensation structure through the third vapor phase pipe 263, and after condensation, forms a liquid with an alcohol concentration reaching the preset alcohol concentration. This liquid is then output to the outside of the product condenser 250 to form the second spirit.

[0093] In some embodiments, the end of the third vapor phase pipe 263 that is connected to the condensing structure is located at the top of the condensing structure, so that the third vapor can flow to the bottom of the barrel after condensing from the top of the condensing structure, thereby fully realizing the heat exchange between the condensing structure and the third vapor and improving energy utilization efficiency.

[0094] See Figure 1 and Figure 2In this embodiment, the product condenser 250 is also connected to the second reflux inlet of the buffer tank 220 to input the product condensate, which has not reached the preset alcohol concentration after the third steam is condensed, into the buffer tank 220. After the product condensate flows back to the buffer tank 220 through the second reflux inlet, it can be processed again by the buffer tank 220, the second distillation column 230, and the third distillation column 240 to form the third steam, and finally condensed again in the product condenser 250 to produce the second spirit with the preset alcohol concentration.

[0095] In some embodiments, a third liquid phase pipe 266 is provided between the product condensation device 250 and the second reflux inlet of the buffer tank 220, so that the liquid in the product condensation device 250 can flow back into the buffer tank 220.

[0096] In some embodiments, the liquid fed into the buffer tank 220 by the product condenser 250 can also be used to mix with the first reflux liquid, the second reflux liquid and the mash to form the first spirit.

[0097] In some embodiments, the second spirit may be vodka with an alcohol concentration of ≥96%.

[0098] In some embodiments, a detector (not shown) may be provided on the product condenser 250. The detector can detect whether the alcohol concentration of the liquid condensed by the product condenser 250 reaches a preset alcohol concentration. If the alcohol concentration of the liquid reaches the preset alcohol concentration, the product condensate is output outside the product condenser 250 to form a second spirit. If the alcohol concentration of the liquid does not reach the preset alcohol concentration, the product condensate is returned to the buffer tank 220 through the third liquid phase pipe 266 for further distillation.

[0099] In some embodiments, control valves may be installed at the outlets and inlets of the first distillation column 210, buffer tank 220, second distillation column 230, third distillation column 240, and product condensation equipment 250 to control the start and stop of each stage of the spirit preparation system. In other embodiments, control valves may be installed on each connecting pipe within the preparation system to control the start and stop of each stage of the spirit preparation system.

[0100] See Figure 1 and Figure 2 In this embodiment, when the spirits preparation system is producing spirits, grains are fed into the mash production component 100. After being cleaned and dried in the grain mash production component 100, the germ inside the grains is removed to form raw materials, and finally the raw materials are subjected to gelatinization, saccharification and fermentation treatments in sequence to form mash.

[0101] After entering the first tower body 211, the mash flows to the bottom of the first tower body 211. The reboiling device 212 can heat and boil the mash. During the heating process, the reboiling device 212 can separate some impurities from the mash to form the first waste liquid. The reboiling device 212 can discharge the first waste liquid to the outside to ensure the safety and reliability of the liquid in the buffer tank 220. The reboiling device 212 heats and boils the mash to evaporate it and form the first steam.

[0102] The first steam flows upward and enters the first condenser 213. Part of the first steam condenses under the action of the first condenser 213 to form condensate, which flows downward to the bottom of the first tower body 211. The other part of the first steam forms waste gas after passing through the first condenser 213 and is discharged to the outside through the waste gas outlet. The condensate flowing to the bottom of the first tower body 211 is the raw liquid. The condensate in the first tower body 211 can enter the tank 221 through the raw liquid inlet.

[0103] After the raw liquid enters the tank body 221 of the buffer tank 220, the heating device 222 heats the raw liquid, and the raw liquid evaporates under heat to form buffer steam.

[0104] The buffer vapor enters the second tower body 231 through the first vapor phase pipe 261 and flows upward within the second tower body 231 to enter the second condenser 232. The second condenser 232 can condense part of the buffer vapor to form a first reflux liquid; the other part of the buffer vapor passes through the second condenser 232 to form second vapor, which can enter the third tower body 241 through the second vapor phase pipe 262.

[0105] After the second steam enters the third tower body 241, it flows upward within the third tower body 241. After the second steam flows into the third condenser 242, part of the second steam is condensed in the third condenser 242 to form the second reflux liquid; the other part of the second steam passes through the third condenser 242 to form the third steam.

[0106] The third vapor can enter the product condenser 250 through the third vapor phase pipe 263. After receiving the third vapor, the product condenser 250 condenses the third vapor into a liquid. When the alcohol concentration of the liquid after condensation of the third vapor reaches the preset alcohol concentration, the product condenser 250 outputs the liquid to form the second spirit.

[0107] When the alcohol concentration of the liquid after the third steam condensation does not reach the preset alcohol concentration, the liquid condensed by the product condenser 250 is input into the buffer tank 220 through the third liquid phase pipe 266, so as to facilitate the production of a second spirit with an alcohol concentration greater than 94% by liquid circulation distillation.

[0108] Furthermore, the second reflux liquid in the third tower body 241 can be refluxed back to the second tower body 231 through the second liquid phase pipe 265, and the liquid in the second tower body 231 can be refluxed back to the buffer tank 220 through the first liquid phase pipe 264. The liquid refluxed back to the buffer tank 220 can be mixed to form the first spirit with an alcohol concentration greater than 40%.

[0109] The spirits preparation system of this application can produce a variety of spirits with different alcohol concentrations while effectively reducing the number of production equipment and the area of ​​production equipment, thereby effectively improving the production efficiency of spirits and reducing the production cost of spirits.

[0110] 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.
