Description

Technical Field

[0001] This invention belongs to the field of baijiu distillation technology, specifically relating to a distillation device for baijiu production. Background Technology

[0002] Baijiu, a traditional Chinese distilled spirit, is made from grains through processes such as saccharification, fermentation, distillation, and aging. It has twelve major aroma categories. The main functions of baijiu distillation include extracting alcohol, concentrating aroma components, cooking and gelatinizing raw materials, and generating distillation heat. The distillation process involves placing the fermented mash into a special container, heating it to generate steam, and then condensing and collecting the steam to obtain the baijiu liquor. Baijiu distillation utilizes the difference in boiling points of the components in the mash to separate alcohol from flavor substances. It is a key step in the baijiu production process, and the performance of the equipment directly determines the yield, alcohol content, and flavor quality of the baijiu.

[0003] However, in existing baijiu distillation equipment, the alcohol vapor directly enters the condenser for condensation during the distillation process, resulting in a lack of flavor enrichment. Volatile organic compounds such as esters and alcohols, which are present in low amounts in the fermentation materials but play a crucial role in the flavor of the liquor, are easily lost in large quantities with the unretained vapor, ultimately leading to a bland flavor, lack of prominent characteristic aromas, and difficulty in forming a unique product style. At the same time, the condenser adopts an overall temperature control mode, which only cools the entire condenser through a single cooling method. It cannot achieve precise temperature control based on the differences in boiling points of alcohol, flavor substances, and impurities. The differences in boiling points of alcohol, impurities, and flavor substances cannot be utilized, and impurities are easily condensed and mixed into the liquor along with the alcohol, resulting in a strong irritant taste in the liquor. An additional purification process is required, which not only prolongs the production cycle but also increases the alcohol loss rate and production costs.

[0004] Therefore, there is an urgent need for a distillation equipment for baijiu production to solve the above problems. Summary of the Invention

[0005] In view of the problems raised in the background art above, the purpose of the present invention is to provide a distillation device for the production of baijiu (Chinese liquor).

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A distillation apparatus for producing baijiu (Chinese liquor) includes a frame, a distillation tank mounted on one side of the top of the frame, a sealing cover mounted on the top of the distillation tank, a steam pipe mounted on the top of the sealing cover, a three-way pipe connected to the output end of the steam pipe, on both sides of the three-way pipe having a switch valve mounted on each side, and a stainless steel corrugated hose connected to the output end of each switch valve. One side of the stainless steel corrugated hose has a steam regeneration mechanism connected to its output end, a segmented temperature-controlled condensing mechanism connected to its output end, and a collection mechanism connected to its output end. The other side of the stainless steel corrugated hose has a vacuum cooling device connected to its output end, and a steam input pipe is connected to one side of the distillation tank. The steam regeneration mechanism includes a steam regeneration tank mounted on a frame. Several stainless steel porous support plates are arranged sequentially from bottom to top inside the steam regeneration tank, and an activated carbon adsorption layer is provided between two adjacent stainless steel porous support plates. The segmented temperature-controlled condensing mechanism includes a condensing pipe mounted on a frame. Sealing plates are bolted to the upper and lower sides of the condensing pipe. Sealing partitions are installed on the upper and lower sides inside the condensing pipe. The condensing pipe is divided into three parts by the internal sealing partitions, forming a temperature-controlled chamber, a first condensing chamber, and a second condensing chamber arranged sequentially from top to bottom. A first spiral tube is installed in the temperature-controlled chamber, a second spiral tube is installed in the first condensing chamber, and a third spiral tube is installed in the second condensing chamber. The first, second, and third spiral tubes are connected to each other.

[0007] Further specifying, an input pipe is installed at the bottom of the steam regeneration tank, and a first transfer pipe is connected to the input pipe via a flange. The input end of the first transfer pipe is connected to the output end of a stainless steel corrugated hose on one side. A main output pipe is installed at the top of the steam regeneration tank, and a second transfer pipe is connected to the main output pipe via a flange. The output end of the second transfer pipe is connected to the input end of a segmented temperature-controlled condensing mechanism. This structural design facilitates disassembly and maintenance through flange connections, while ensuring reliable sealing performance.

[0008] Further specifying, a secondary output pipe is installed on one side of the steam regeneration tank, and nitrogen inlet and outlet pipes are installed on the upper and lower sides of the side wall of the steam regeneration tank. The nitrogen inlet and outlet pipes are connected to an external nitrogen heating and circulation device. An air compressor is connected to the output end of the secondary output pipe, and a secondary pipe is connected to the output end of the air compressor. A one-way valve is installed inside the secondary pipe, and the output end of the secondary pipe is connected to a steam input pipe. This structural design allows for the desorption of flavor substances through nitrogen circulation to form regenerated wine vapor, and also allows for the recirculation of auxiliary steam, improving steam utilization.

[0009] Furthermore, the activated carbon adsorption layer includes a mesh bag installed between two adjacent porous stainless steel support plates, the mesh bag being filled with a plurality of activated carbon particles, the diameter of which is 2-3 mm. This structural design allows for the adsorption of flavor substances in the alcohol vapor, facilitating subsequent desorption of flavor substances by hot nitrogen.

[0010] Further specifying, a first input pipe is installed on one side of the top of the temperature control cavity, a first output pipe is installed on one side of the bottom of the temperature control cavity, and electric heating tubes are installed on all four sides inside the temperature control cavity. A second input pipe is installed on one side of the bottom of the first condensing cavity, a second output pipe is installed on one side of the top of the first condensing cavity, a third input pipe is installed on one side of the top of the second condensing cavity, and a third output pipe is installed on one side of the bottom of the second condensing cavity. Temperature sensors are installed in the temperature control cavity, the first condensing cavity, and the second condensing cavity. A heat insulation layer is provided inside the temperature control cavity, and a heat preservation layer is provided inside the second condensing cavity. This structural design allows for the separate delivery of media at different temperatures for temperature-controlled condensation, while also facilitating subsequent temperature regulation.

[0011] Further specified, the input end of the first spiral tube is connected to the output end of the steam regeneration mechanism, the output end of the first spiral tube is connected to a first adapter pipe, the output end of the first adapter pipe is connected to the input end of the second spiral tube, the output end of the second spiral tube is connected to a second adapter pipe, the output end of the second adapter pipe is connected to the input end of the third spiral tube, and the output end of the third spiral tube is connected to a collecting mechanism. This structural design facilitates the connection and use of the first, second, and third spiral tubes.

[0012] Further specifying, the first spiral tube is inclined at 10° to the horizontal and wound 8-9 times, the second spiral tube is inclined at 15° to the horizontal and wound 14-18 times, and the third spiral tube is inclined at 12° to the horizontal and wound 10-12 times. This structural design, through differentiated inclination angles, avoids insufficient contact caused by excessive inclination and excessively fast flow, ensuring the stability and uniformity of the flow.

[0013] Further specifying, the input end of the first spiral tube is connected to a condensation delivery pipe, which is sealed and mounted on the upper sealing plate. The input end of the condensation delivery pipe is connected to the output end of the second transfer pipe via a flange. The output end of the third spiral tube is equipped with a liquid outlet pipe, which is sealed and mounted on the lower sealing plate. The output end of the liquid outlet pipe is connected to a collection mechanism. This structural design facilitates the connection of the first spiral tube to the input and the third spiral tube to the output.

[0014] Furthermore, the first adapter pipe is installed through the upper sealing partition, and the second adapter pipe is installed through the lower sealing partition. Sealing seats are provided on both sides of the sealing partitions at the point where the first and second adapter pipes pass through. This structural design ensures that the first and second adapter pipes are sealed during installation.

[0015] Furthermore, the stainless steel corrugated hose, input pipe, first transfer pipe, main output pipe, second transfer pipe, and condensate delivery pipe are all configured with a double-layer insulation structure. This structural design reduces steam loss during the transportation process.

[0016] The beneficial effects of this invention are as follows: 1. This invention achieves the directional enrichment of flavor substances by setting up a steam regeneration mechanism and using a combination of activated carbon adsorption and hot nitrogen desorption. The wine vapor first passes through the activated carbon adsorption layer on the stainless steel porous support plate, where volatile flavor substances are efficiently adsorbed, preventing them from being lost with the unretained steam. Then, through hot nitrogen circulation desorption, the adsorbed flavor substances are reintegrated into the steam to form regenerated steam, ensuring a significant increase in the retention rate of key flavor substances, thereby solving the problems of bland wine flavor and lack of prominent characteristic aromas.

[0017] 2. This invention utilizes a segmented temperature-controlled condensation mechanism to achieve layered condensation based on the differences in boiling points of substances, thereby eliminating the need for additional purification processes. Temperature is maintained by an electric heating element and insulation medium within the temperature-controlled chamber, preventing premature condensation of high-boiling-point flavor compounds and excessive volatilization of low-boiling-point impurities, thus ensuring flavor purity. Countercurrent heat exchange in the first condensation chamber allows for rapid condensation of alcohol and most flavor compounds. Finally, a 0°C ice-water mixture in the second condensation chamber further condenses residual vapors and the initially condensed liquor, preventing the retention of low-boiling-point impurities. This eliminates the need for additional purification processes, reducing the liquor's irritation, shortening the production cycle, and minimizing alcohol loss during purification.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a distillation device for producing baijiu (Chinese liquor) includes a frame 1, a distillation tank 2 mounted on one side of the top of the frame 1, a sealing cover 3 mounted on the top of the distillation tank 2, a steam pipe 4 mounted on the top of the sealing cover 3, a three-way pipe 5 connected to the output end of the steam pipe 4, a switch valve 6 mounted on both sides of the three-way pipe 5, a stainless steel corrugated hose 7 connected to the output end of the switch valve 6, a steam regeneration mechanism 8 connected to the output end of one side of the stainless steel corrugated hose 7, a segmented temperature-controlled condensing mechanism 9 connected to the output end of the steam regeneration mechanism 8, a collection mechanism 10 connected to the output end of the segmented temperature-controlled condensing mechanism 9, a vacuum cooling device 11 connected to the output end of the other side of the stainless steel corrugated hose 7, and a steam input pipe 12 connected to one side of the distillation tank 2. The steam regeneration mechanism 8 includes a steam regeneration tank 801 mounted on the frame 1. Several stainless steel porous support plates 802 are arranged sequentially from bottom to top inside the steam regeneration tank 801, and an activated carbon adsorption layer 803 is provided between two adjacent stainless steel porous support plates 802. The segmented temperature-controlled condensing mechanism 9 includes a condensing pipe 901 mounted on a frame 1. Sealing plates 902 are bolted to the upper and lower sides of the condensing pipe 901. Sealing partitions 903 are installed inside the condensing pipe 901 on both the upper and lower sides. The condensing pipe 901 is divided into three parts by the sealing partitions 903, forming a temperature-controlled chamber 904, a first condensing chamber 905, and a second condensing chamber 906 arranged sequentially from top to bottom. A first spiral tube 9010 is installed in the temperature-controlled chamber 904, a second spiral tube 9013 is installed in the first condensing chamber 905, and a third spiral tube 9016 is installed in the second condensing chamber 906. The first spiral tube 9010, the second spiral tube 9013, and the third spiral tube 9016 are connected to each other.

[0021] In this embodiment, during use, the mash is first placed into the distillation tank 2, and the sealing cap 3 is placed on top to ensure a sealed state inside the distillation tank 2. Simultaneously, the valve 6 on one side of the vacuum cooling device 11 is closed, and the valve 6 on one side of the steam regeneration mechanism 8 is opened. By connecting the input end of the steam input pipe 12 to the external steam generating unit, the steam generated by the external steam generating unit enters the distillation tank 2 through the steam input pipe 12. Upon contact with the mash, the steam generates alcohol vapor. The alcohol vapor rises and enters the three-way pipe 5 through the top steam pipe 4, and then enters the stainless steel corrugated hose 7. The stainless steel corrugated hose 7 inputs the alcohol vapor into the steam regeneration mechanism 8, where it undergoes hot nitrogen circulation desorption and volatile matter removal. Organic matter is used to enrich flavor compounds and generate regenerated steam. The regenerated steam is output from the steam regeneration mechanism 8 and enters the segmented temperature-controlled condensing mechanism 9. The segmented temperature-controlled condensing mechanism 9 condenses the liquid into liquor in stages and finally flows into the collection mechanism 10, completing the distillation process of baijiu production. Finally, the vacuum cooling device 11 is started and the switch valve 6 on one side of the vacuum cooling device 11 is opened, while the switch valve 6 on the side of the steam regeneration mechanism 8 is closed. This allows the vacuum cooling device 11 to quickly cool the inside of the distillation tank 2 through the connected stainless steel corrugated hose 7, tee pipe 5, and steam pipe 4. After cooling is completed, the vacuum cooling device 11 is closed, the sealing cover 3 is opened, and the residue inside the distillation tank 2 is cleaned. After cleaning, the mash can be put back in and the distillation process can continue.

[0022] When the alcohol vapor is introduced into the steam regeneration tank 801 through the stainless steel corrugated hose 7, it passes sequentially through the activated carbon adsorption layer 803 on the stainless steel porous support plate 802. The activated carbon adsorption layer 803 adsorbs the flavor substances in the alcohol vapor. Then, hot nitrogen is introduced, which desorbs the flavor substances to form regenerated steam. The regenerated steam exits from the steam regeneration tank 801 and enters the first spiral tube 9010 in the condensation pipe 901, flowing along the first spiral tube 9010. At the same time, the first input pipe 907 introduces the heat preservation liquid, and the electric heating tube 909 is activated simultaneously to ensure that the temperature in the temperature control chamber 904 is maintained at 65-75℃. This prevents high-boiling-point flavor substances from condensing prematurely and entering the liquor, which would affect the purity of the liquor flavor. At the same time, it gently extracts low-boiling-point substances, avoiding high temperatures from disrupting the flavor balance. Afterward, the alcohol vapor enters the second spiral tube 901 in the first condensation chamber 905 through the first transfer pipe 9017. In step 3, when the alcohol vapor flows in the second spiral tube 9013, cooling water is introduced through the second input pipe 9011 on one side of the bottom of the first condensing chamber 905. The water flow rate is 1.5-2.0 m / s and the temperature is 15-25℃. It flows from bottom to top and is output through the second output pipe 9012, forming a countercurrent with the flow of alcohol vapor. This creates a continuous temperature gradient, ensuring that the high-temperature steam and the low-temperature cooling water are always in direct contact. The cooling water exchanges heat with the alcohol vapor rapidly through the countercurrent. After heat exchange, the alcohol vapor cools down and forms alcohol liquid, which flows and enters the third spiral tube 9016 through the second transfer pipe 9018. At the same time, a 0℃ ice-water mixture is introduced into the second condensing chamber 906 through the third input pipe 9014. After heat exchange, it is output from the third output pipe 9015. The initially condensed alcohol liquid and residual alcohol vapor are further condensed in the 0℃ ice bath environment. Finally, the alcohol liquid flows out from the condensing pipe 901 and enters the collection mechanism 10.

[0023] The extracted low-boiling-point substances can be removed after being output from the segmented temperature-controlled condensation mechanism 9.

[0024] To ensure the distillation effect of the distillation tank 2, the following structure is added to the distillation tank 2: the distillation tank 2 includes an insulation layer 201, a distillation layer 202 is installed inside the insulation layer 201, the bottom of the distillation layer 202 is provided with several evenly arranged distillation holes 203, a steam distribution plate 204 is installed on the inner bottom of the insulation layer 201, the input end of the steam distribution plate 204 is connected to the output end of the steam input pipe 12, the steam distribution plate 204 is located directly below the distillation layer 202, the steam distribution plate 204 is a circular stainless steel plate, the bottom of the steam distribution plate 204 is provided with evenly distributed supports 205 fixed inside the insulation layer 201, and several steam holes 206 are opened on the steam distribution plate 204 to ensure that the steam holes 206 are evenly distributed from the edge to the center of the steam distribution plate 204.

[0025] In use, steam is output from steam inlet pipe 12 and enters steam distribution plate 204. Steam distribution plate 204 distributes steam evenly and outputs it from several steam holes 206. Steam enters the interior of distillation layer 202 through distillation hole 203 at the bottom of distillation layer 202 and comes into contact with the mash placed inside distillation layer 202, generating alcohol vapor. Insulation layer 201 can reduce heat loss and improve the performance.

[0026] To facilitate cleaning of the distillation tank 2, the following structure is added to the distillation tank 2: a rotating column 13 is installed on one side of the distillation tank 2, and a hollow column 14 is installed on the other side of the distillation tank 2. Bearing seats 15 are installed on the outer sides of both the rotating column 13 and the hollow column 14. The bearing seats 15 are locked onto the frame 1 by screws. The outer side of the rotating column 13 passes through the bearing seat 15 and extends to the outer side to connect to a first transmission wheel 16. The first transmission wheel 16 is connected to a transmission belt 17. The other side of the transmission belt 17 is connected to a second transmission wheel 18. The second transmission wheel 18 is connected to a drive motor 19. The drive motor 19 is installed on the frame 1, and its power output end is connected to the second transmission wheel 18. The outer side of the hollow column 14 passes through the bearing seat 15 and extends to the outer side. A sealed bearing 20 is installed on the outer side of the hollow column 14. The sealed bearing 20 is installed in the output end of the steam input pipe 12. The output end of the hollow column 14 is connected to the steam distribution plate 204.

[0027] When in use, after the distillation is completed and the vacuum cooling device 11 has cooled the distillation tank 2, the sealing cover 3 is opened. When it is necessary to clean the residue inside the distillation tank 2, the drive motor 19 is started. The drive motor 19 drives the second transmission wheel 18 to rotate. The second transmission wheel 18 drives the transmission belt 17 while rotating. The transmission belt 17 drives the first transmission wheel 16. The first transmission wheel 16 drives the rotating column 13 to rotate in the bearing seat 15. The rotating column 13 drives the distillation tank 2 in sync. The other side of the distillation tank 2 drives the hollow column 14 to rotate along the bearing seat 15, causing the distillation tank 2 to tilt. This moves the mouth of the distillation tank 2 from the top to the bottom, making it easier for the operator to clean the inside of the distillation tank 2.

[0028] When the hollow column 14 rotates within the bearing housing 15, the outer side of the hollow column 14 is connected to the steam input pipe 12 through the sealed bearing 20, ensuring a smooth connection and not affecting subsequent steam delivery.

[0029] The maximum external dimension of the first transmission wheel 16 is larger than that of the second transmission wheel 18, ensuring slow transmission for ease of subsequent operation.

[0030] To facilitate the handling of distillation residues and the transfer of liquor, the following structure is added to the frame 1: a first conveyor line 101 is installed at the bottom of the distillation tank 2, and a second conveyor line 102 is installed at the bottom of the collection mechanism 10. The conveyor belts on the first conveyor line 101 and the second conveyor line 102 are both made of polytetrafluoroethylene.

[0031] During use, the distillation tank 2 is tilted by the drive motor 19, and the distillation tank 2 tilts to pour out the distilled residue onto the first conveyor line 101. The residue is then output by the first conveyor line 101 for subsequent processing. At the same time, the operator can also clean the residue adhering to the inner wall of the distillation tank 2 onto the first conveyor line 101 to facilitate transfer and output and reduce manual labor intensity. Meanwhile, the second conveyor line 102 located at the bottom of the collection mechanism 10 can transport the wine container to the bottom of the collection mechanism 10. The collection mechanism 10 fills the collected wine container into the wine container and then transports the wine container to the subsequent work station for processing via the second conveyor line 102.

[0032] To facilitate the opening and closing of the sealing cover 3, the following structure is added to the sealing cover 3: A mounting base 301 is installed on the top of the sealing cover 3; the steam pipe 4 is installed inside the mounting base 301; fixed posts 302 are installed on both sides of the mounting base 301; movable arms 303 are rotatably connected to the outer sides of the two fixed posts 302; a reinforcing post 304 is installed between the two movable arms 303; a hinge plate 305 is connected to the other side of the movable arm 303; a column 306 is installed at the bottom of the hinge plate 305; and the bottom of the column 306... Mounted on the frame 1, the column 306 has a clearance groove 307 on one side. The bottom of the clearance groove 307 is fitted with a hinge seat 308. The top of the hinge seat 308 is fitted with a hydraulic cylinder 309. The power output end of the hydraulic cylinder 309 is connected to a movable head 3010. The movable head 3010 is connected to a connecting rod 3011. The two sides of the connecting rod 3011 are fitted with rocker plates 3012. The rocker plates 3012 are fixedly mounted on the movable arm 303. The rocker plates 3012 and the movable arm 303 are integrally formed.

[0033] When closure is required, the hydraulic cylinder 309 is controlled to push the movable head 3010 upwards from its power output end. The movable head 3010 drives the connecting rod 3011, which in turn drives the rocker arm 3012. The rocker arm 3012 then drives the movable arm 303, causing it to rotate at the hinge point with the hinge plate 305. This causes the movable arm 303 to drive the fixed column 302, which in turn drives the mounting base 301. The mounting base 301 then causes the sealing cover 3 to press down onto the distillation tank 2. To open, the power output end of the hydraulic cylinder 309 drives the movable head 3010 downward, the movable head 3010 drives the connecting rod 3011, the connecting rod 3011 drives the rocker arm 3012, the rocker arm 3012 drives the movable arm 303, causing the movable arm 303 to rotate at the hinge point with the hinge plate 305 and tilt upward, thereby causing the movable arm 303 to drive the fixed column 302, the fixed column 302 to drive the mounting base 301, and the mounting base 301 to drive the sealing cover 3 away from the distillation tank 2, thus opening the distillation tank 2.

[0034] The collection mechanism 10 includes a collection tank 1001, which is made of 304 stainless steel. The top of the collection tank 1001 is provided with a feed inlet 1002, which is connected to the output end of the liquid outlet pipe 9023. The bottom output end of the collection tank 1001 is equipped with a discharge valve 1003, and a support frame 1004 is installed on the outside of the collection tank 1001.

[0035] During use, the wine output from the outlet pipe 9023 is fed into the collection tank 1001 through the inlet 1002. When the second conveyor line 102 moves the bottom of the wine container to the outlet valve 1003, the outlet valve 1003 is opened, allowing the wine inside the collection tank 1001 to be loaded into the wine container. Finally, the wine container is transported to the subsequent work station through the second conveyor line 102.

[0036] Among them, the vacuum cooling device 11 is a mature existing technology, capable of achieving efficient heat dissipation. Example 2, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure to the embodiment 1: an input pipe 804 is installed at the bottom of the steam regeneration tank 801, and a first transfer pipe 805 is installed on the input pipe 804 through a flange. The input end of the first transfer pipe 805 is connected to the output end of one of the stainless steel corrugated hoses 7. A main output pipe 806 is installed at the top of the steam regeneration tank 801, and a second transfer pipe 807 is connected to the main output pipe 806 through a flange. The output end of the second transfer pipe 807 is connected to the input end of the segmented temperature-controlled condensing mechanism 9.

[0037] In this embodiment, during use, the alcohol vapor output from the distillation tank 2 is input into the first transfer pipe 805 through the stainless steel corrugated hose 7. The alcohol vapor flows in the first transfer pipe 805 and enters the inner bottom of the steam regeneration tank 801 through the input pipe 804. The alcohol vapor passes through the activated carbon adsorption layer 803 on the stainless steel porous support plate 802 in sequence. The activated carbon adsorption layer 803 adsorbs the flavor substances in the alcohol vapor. Then, hot nitrogen is input to desorb the flavor substances and form regenerated steam. The regenerated steam is output from the main output pipe 806 and enters the second transfer pipe 807, and is input into the segmented temperature-controlled condensation mechanism 9 through the second transfer pipe 807.

[0038] Example 3, as Figure 2 , Figure 5 and Figure 8 As shown, this embodiment adds the following structure based on embodiment 1: A secondary output pipe 808 is installed on one side of the steam regeneration tank 801; a nitrogen inlet pipe 809 and a nitrogen outlet pipe 8010 are installed on the upper and lower sides of the side wall of the steam regeneration tank 801; the nitrogen inlet pipe 809 and the nitrogen outlet pipe 8010 are connected to an external nitrogen heating and circulation device; the output end of the secondary output pipe 808 is connected to an air compressor 8011; the output end of the air compressor 8011 is connected to a secondary pipe 8012; a one-way valve is installed inside the secondary pipe 8012; and the output end of the secondary pipe 8012 is connected to the steam input pipe 12.

[0039] In this embodiment, during use, the alcohol vapor enters the steam regeneration tank 801 through the input pipe 804. The alcohol vapor passes sequentially through the activated carbon adsorption layer 803 on the stainless steel porous support plate 802, where the activated carbon adsorption layer 803 adsorbs the flavor substances in the alcohol vapor. Then, the external nitrogen heating circulation device is activated, allowing hot nitrogen to enter through the nitrogen inlet pipe 809. The hot nitrogen desorbs the flavor substances to form regenerated steam, which is output from the main output pipe 806. The nitrogen is output from the nitrogen outlet pipe 8010 back to the external nitrogen heating circulation device, where it is reheated and then input back into the steam regeneration tank 801 for use. The residual steam in the steam regeneration tank 801 is output through the auxiliary output pipe 808 into the air compressor 8011, where it is heated. The one-way valve in the auxiliary pipe 8012 is opened, allowing the steam to re-enter the steam input pipe 12 through the auxiliary pipe 8012 and be input back into the distillation tank 2 for distillation.

[0040] Among them, the input pipe 804, the main output pipe 806, the auxiliary output pipe 808, the nitrogen inlet pipe 809, and the nitrogen outlet pipe 8010 are all equipped with electrically controlled valves to facilitate the control of the input and output of alcohol vapor and nitrogen.

[0041] Example 4, as Figure 5As shown, this embodiment adds the following structure to the original embodiment 1: the activated carbon adsorption layer 803 includes a mesh bag 8013 installed between two adjacent stainless steel porous support plates 802, and the mesh bag 8013 is filled with a number of activated carbon particles 8014, the diameter of which is 2-3 mm.

[0042] In this embodiment, a mesh bag 8013 is used to fill activated carbon particles 8014 so that they can be removed and replaced when maintenance is required. At the same time, the 2-3 mm activated carbon particles 8014 adsorb flavor substances in the wine vapor so that the flavor substances can be desorbed after hot nitrogen is introduced.

[0043] Example 5, as Figure 3 and Figure 6 As shown, this embodiment adds the following structure to Embodiment 1: a first input pipe 907 is installed on one side of the top of the temperature control cavity 904, a first output pipe 908 is installed on one side of the bottom of the temperature control cavity 904, and electric heating tubes 909 are installed on all four sides inside the temperature control cavity 904. A second input pipe 9011 is installed on one side of the bottom of the first condensing cavity 905, a second output pipe 9012 is installed on one side of the top of the first condensing cavity 905, a third input pipe 9014 is installed on one side of the top of the second condensing cavity 906, and a third output pipe 9015 is installed on one side of the bottom of the second condensing cavity 906. Temperature sensors 9019 are installed in the temperature control cavity 904, the first condensing cavity 905, and the second condensing cavity 906. A heat insulation layer 9020 is provided inside the temperature control cavity 904, and a heat preservation layer 9021 is provided inside the second condensing cavity 906. This structural design allows for the separate delivery of media at different temperatures for temperature-controlled condensation, while also facilitating subsequent temperature regulation.

[0044] In this embodiment, during use, the first input pipe 907 introduces the heat-insulating liquid, and the electric heating tube 909 is simultaneously activated to ensure that the temperature inside the temperature control chamber 904 is between 65 and 75°C. This prevents high-boiling-point flavor substances from condensing prematurely and entering the liquor, affecting the purity of the liquor's flavor. Simultaneously, it gently extracts low-boiling-point substances, avoiding high temperatures that could disrupt the flavor balance. Then, as the liquor vapor flows in the second spiral tube 9013, cooling water is introduced through the second input pipe 9011 on one side of the bottom of the first condensation chamber 905. The water flow rate is 1.5–2.0 m / s, and the temperature is 15–25°C. The water flows upwards and is output through the second output pipe 9012, forming a counter-current with the liquor vapor flow. This creates a continuous temperature gradient, ensuring that the high-temperature steam and low-temperature cooling water are always in direct contact. This allows the cooling water to rapidly exchange heat with the liquor vapor through the counter-current flow. After heat exchange, the liquor vapor cools down, forming the liquor that enters the third spiral tube 9016. Simultaneously, the third input pipe… A 0°C ice-water mixture is input into the second condensing chamber 906 via pipe 9014. After heat exchange, it is output from the third output pipe 9015. The initially condensed wine and residual wine vapor are further condensed in the 0°C ice bath environment. Finally, the wine flows out from the condensing pipe 901 and enters the collection mechanism 10. During the temperature-controlled condensation process, temperature sensors 9019 are installed in the temperature control chamber 904, the first condensing chamber 905, and the second condensing chamber 906, respectively. The temperature data inside each chamber can be collected in real time and independently. This allows for a comprehensive understanding of the temperature status of each functional chamber, providing accurate information for subsequent judgment on whether adjustment is needed and which chamber to adjust. At the same time, the heat insulation layer 9020 effectively blocks heat exchange between the inside and outside of the chamber, reducing the impact of external environmental temperature fluctuations on the internal temperature of the temperature control chamber. The heat insulation layer 9021 reduces the loss of cold energy inside the chamber, helping the condensing chamber to continuously maintain the low-temperature environment required for efficient condensation.

[0045] Example 6, as Figure 3 and Figure 6 As shown, this embodiment adds the following structure to Embodiment 1: the input end of the first spiral tube 9010 is connected to the output end of the steam regeneration mechanism 8; the output end of the first spiral tube 9010 is connected to a first adapter pipe 9017; the output end of the first adapter pipe 9017 is connected to the input end of the second spiral tube 9013; the output end of the second spiral tube 9013 is connected to a second adapter pipe 9018; the output end of the second adapter pipe 9018 is connected to the input end of the third spiral tube 9016; and the output end of the third spiral tube 9016 is connected to the collecting mechanism 10. This structural design facilitates the connection and use of the first spiral tube 9010, the second spiral tube 9013, and the third spiral tube 9016.

[0046] In this embodiment, during use, the regenerated steam is output from the steam regeneration tank 801 and enters the first spiral tube 9010 in the condensation pipe 901, and flows along the first spiral tube 9010. Then, the alcohol vapor enters the second spiral tube 9013 in the first condensation chamber 905 through the first transfer pipe 9017. After heat exchange, the alcohol vapor cools down to form liquid alcohol, which flows and enters the third spiral tube 9016 through the second transfer pipe 9018. The initially condensed liquid alcohol and residual alcohol vapor are further condensed in the third spiral tube 9016. Finally, the liquid alcohol flows out from the third spiral tube 9016 and enters the collection mechanism 10.

[0047] Example 7, as Figure 6 As shown, this embodiment adds the following structure to the basis of embodiment 1: the first spiral tube 9010 is set at a horizontal inclination of 10° and wound 8 to 10 times; the second spiral tube 9013 is set at a horizontal inclination of 15° and wound 14 to 18 times; and the third spiral tube 9016 is set at a horizontal inclination of 12° and wound 10 to 12 times.

[0048] In this embodiment, during use, the first spiral tube 9010, which is inclined at 10° horizontally, serves as the initial section to slow down the steam speed. The second spiral tube 9013, which is inclined at 15° horizontally, has more winding turns to balance the steam flow rate, allowing the steam to dissipate heat sufficiently within the second spiral tube 9013. Finally, the third spiral tube 9016, which is inclined at 12° horizontally, serves as the finishing section to stabilize the gas and fluid state and perform final condensation. The number of winding turns of the first and third spiral tubes provides suitable contact conditions for initial buffering and final condensation, avoiding insufficient heat exchange due to insufficient number of turns.

[0049] The first spiral tube 9010 is inclined at 10° to the horizontal, which can effectively slow down the speed of the steam after it enters, and prevent the steam from rushing directly into the subsequent pipeline due to the initial flow rate being too fast. The second spiral tube 9013 is inclined at 15° to the horizontal, which can balance the steam flow rate, so that the flow rate is not too slow and will not cause accumulation in the pipeline, nor will the flow rate be too fast and shorten the heat exchange time. The third spiral tube 9016 is inclined at 12° to the horizontal, which can stabilize the mixing state of the steam and the condensed fluid, and prevent incomplete condensation due to flow rate fluctuations in the final stage, thus ensuring the final condensation effect.

[0050] The first spiral tube 9010, wound 8-10 times, provides a basic contact area, which can both buffer the initial flow rate and prevent premature condensation of steam due to excessive number of turns. The second spiral tube 9013, wound 14-18 times, increases the contact area and residence time between the steam and the pipeline, allowing the steam sufficient time to release heat and achieve full heat exchange. The third spiral tube 9016, wound 10-12 times, ensures that the incompletely condensed steam is completely converted into fluid, avoiding residual heat exchange due to insufficient number of turns.

[0051] The inclination angles of the first spiral tube 9010, the second spiral tube 9013, and the third spiral tube 9016, combined with the number of winding turns, form a closed loop from flow rate to heat exchange. The inclination angle controls the flow rate, creating a prerequisite for the number of winding turns to play its role, while the number of winding turns ensures the heat exchange effect, thus inheriting the results of the flow rate control achieved by the inclination angle.

[0052] Example 8, as Figure 2 , Figure 3 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the input end of the first spiral tube 9010 is connected to a condensation conveying pipe 9022, the condensation conveying pipe 9022 is sealed and installed on the upper sealing plate 902, the input end of the condensation conveying pipe 9022 is connected to the output end of the second transfer pipe 807 through a flange, the output end of the third spiral tube 9016 is equipped with a liquid outlet pipe 9023, the liquid outlet pipe 9023 is sealed and installed on the lower sealing plate 902, and the output end of the liquid outlet pipe 9023 is connected to the collection mechanism 10.

[0053] In this embodiment, during use, the regenerated steam is output from the second transfer pipe 807 and enters the first spiral pipe 9010 through the condenser conveying pipe 9022. It then passes through the first spiral pipe 9010, the first transfer pipe 9017, the second spiral pipe 9013, the second transfer pipe 9018, and the third spiral pipe 9016 in sequence. Finally, the liquid is output from the liquid outlet pipe 9023 and enters the collection mechanism 10, ensuring that the steam enters the spiral pipe efficiently and the processed liquid enters the collection mechanism smoothly, thereby improving the overall working efficiency of the equipment.

[0054] Example 9, as Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the first adapter pipe 9017 is installed through the upper sealing partition 903, the second adapter pipe 9018 is installed through the lower sealing partition 903, and the upper and lower sealing partitions 903 are provided with sealing seats 9024 on the upper and lower sides of the passage of the first adapter pipe 9017 and the second adapter pipe 9018.

[0055] In this embodiment, by setting the sealing seat 9024, a bidirectional sealing structure is formed between the first adapter pipe 9017 and the second adapter pipe 9018 and the sealing partition 903, which can more comprehensively block the leakage of the medium between the two adjacent cavities from the through gap, and achieve a good sealing effect.

[0056] Example 10, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the stainless steel corrugated hose 7, the input pipe 804, the first transfer pipe 805, the main output pipe 806, the second transfer pipe 807, and the condensate delivery pipe 9022 are all set with a double-layer heat preservation structure.

[0057] In this embodiment, a double-layer insulation structure forms a heat insulation barrier on the inner and outer sides of the stainless steel corrugated hose 7, input pipe 804, first transfer pipe 805, main output pipe 806, second transfer pipe 807, and condensate delivery pipe 9022. This effectively prevents the heat of steam from dissipating during the transportation process, reduces condensation caused by steam cooling, and lowers losses. At the same time, the double-layer insulation layer can effectively reduce the temperature of the outer surface of the pipeline, preventing the outer wall of the pipeline from overheating due to high steam temperature, thereby reducing the risk of burns to operators when accidentally contacting it.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
