[0024] When producing whisky, the grains need to be germinated, saccharified, and fermented in sequence to form a fermentation broth, and the fermentation broth needs to go through processes such as distillation and condensation before whisky liquor can be produced.

[0025] Refer to Figure 1 , the present application provides a whisky distillation system, which is connected to an external fermentation broth source for receiving the external fermentation broth and capable of processing the fermentation broth into liquor.

[0026] Refer to Figure 1 , for the convenience of understanding and description, the state when the whisky distillation system is placed on the working ground is taken as a reference. The direction of the whisky distillation system relative to the working ground is the upper direction in the following text, and the direction away from the upper direction is the lower direction in the following text.

[0027] Refer to Figure 1, this application provides a whisky distillation system, which includes: a distiller 100, a liquid inlet assembly 200, a heating assembly 400, and an energy recovery assembly 500. A distillation space is provided inside the distiller 100. The liquid inlet assembly 200 is connected to the distiller 100 for inputting fermented liquid into the distillation space. The heating assembly 400 is arranged upstream of the distiller 100 for heating the fermented liquid to form alcohol vapor. A refrigerant flows inside the energy recovery assembly 500. The energy recovery assembly 500 includes a condenser 510, a flash tank 520, and a mechanical pressurizer 530 that are connected in sequence. The condenser 510 is connected to the distiller 100 to receive alcohol vapor, and the mechanical pressurizer 530 exchanges heat with the liquid inlet assembly 200. Among them, the refrigerant inside the condenser 510 exchanges heat with the alcohol vapor to form a high-temperature liquid. The flash tank 520 receives the high-temperature liquid and flashes the high-temperature liquid to form flash vapor. The mechanical pressurizer 530 receives the flash vapor and pressurizes and heats the flash vapor under high pressure to form high-temperature vapor. The high-temperature vapor is used to heat the fermented liquid to form alcohol vapor.

[0028] When the whisky distillation system (hereinafter referred to as the distillation system) works, the fermented liquid from an external fermented liquid source enters the distiller 100 through the liquid inlet assembly 200. The heating assembly 400 is used to heat the fermented liquid in the liquid inlet assembly 200 so that the fermented liquid evaporates to form alcohol vapor.

[0029] The alcohol vapor formed by the evaporation of the fermented liquid in the distiller 100 enters the energy recovery assembly 500. The alcohol vapor exchanges heat with the refrigerant in the condenser 510 so that the alcohol vapor condenses to form whisky liquor, and the refrigerant heats up to form a high-temperature liquid.

[0030] The high-temperature liquid output by the condenser 510 enters the flash tank 520, and the flash tank 520 flashes the high-temperature liquid to form flash vapor. The flash vapor then enters the mechanical pressurizer 530, and the mechanical pressurizer 530 can pressurize and heat up under a high-pressure environment to form high-temperature vapor. The high-temperature vapor then exchanges heat with the liquid inlet assembly 200, causing the fermented liquid to be heated and evaporated, thus realizing the reuse of the waste heat in the alcohol vapor, greatly reducing the dependence of the distillation system on external energy, improving the energy utilization efficiency of the distillation system, reducing the production cost of the distillation system, and improving the production efficiency of the liquor. Moreover, it can also effectively reduce the use of traditional fossil energy by the distillation system and reduce the emission of greenhouse gases such as carbon dioxide, contributing to the realization of the sustainable development goal of the whisky industry.

[0031] In some embodiments, the refrigerant can be water.

[0032] Refer to Figure 1, in this embodiment, the distillation system includes a distiller 100. A distillation space is provided inside the distiller 100, which is used to accommodate the fermented liquid and can output the alcohol vapor formed after the fermented liquid is heated and evaporated into the energy recovery component 500.

[0033] The distiller 100 includes a tank body 110, a swan neck 120 and a lyne arm 130. The tank body 110 is used to store the fermented liquid. The fermented liquid can be evaporated in the tank body 110 to form alcohol vapor. The swan neck 120 is arranged at the top of the tank body 110. The swan neck 120 extends in the up and down direction, and the lower end of the swan neck 120 is communicated with the tank body 110, so that the alcohol vapor in the tank body 110 can flow upward into the swan neck 120. One end of the lyne arm 130 is communicated with the upper end of the swan neck 120, and the other end of the lyne arm 130 is communicated with the energy recovery component 500. The alcohol vapor output by the swan neck 120 can be input into the energy recovery component 500 through the lyne arm 130.

[0034] In some embodiments, the bottom of the tank body 110 has a downwardly protruding conical structure, so as to facilitate the convergence of the fermented liquid at the bottom of the tank body 110 and avoid the residue of the fermented liquid in the tank body 110.

[0035] In some embodiments, the lyne arm 130 is inclined. The end of the lyne arm 130 connected to the swan neck 120 is higher than the end of the lyne arm 130 connected to the energy recovery component 500. The inclined setting of the lyne arm 130 can enable the alcohol vapor to flow quickly into the energy recovery component 500, reduce the backflow, and thus retain more heavy flavor substances.

[0036] In some embodiments, the lyne arm 130 is inclined. The end of the lyne arm 130 connected to the swan neck 120 is lower than the end of the lyne arm 130 connected to the energy recovery component 500. The inclined setting of the lyne arm 130 can enable part of the alcohol vapor to condense and flow back into the tank body 110 before the alcohol vapor flows into the energy recovery component 500, thereby helping to separate impurities and retaining more pure alcohol and flavor substances.

[0037] Refer to Figure 1 , in this embodiment, the distillation system includes a liquid inlet component 200, and the liquid inlet component 200 can be connected to an external fermented liquid source to input the fermented liquid into the distiller 100.

[0038] The liquid inlet component 200 includes a main liquid inlet pipe 210, a first liquid distribution pipe 220 and a second liquid distribution pipe 230. One end of the main liquid inlet pipe 210 is used to connect to an external fermented liquid source, and the other end is used to connect to the first liquid distribution pipe 220 and the second liquid distribution pipe 230 respectively. The ends of the first liquid distribution pipe 220 and the second liquid distribution pipe 230 facing away from the main liquid inlet pipe 210 are respectively connected to the distiller 100. The second liquid distribution pipe 230 is connected to the heating component 400.

[0039] The main inlet pipe 210 can input the fermentation broth in the fermentation broth source into the first distribution pipe 220 and / or the second distribution pipe 230 respectively. The fermentation broth in the first distribution pipe 220 and the second distribution pipe 230 is then respectively input into the distiller 100, so as to facilitate the rapid filling of the distillation space.

[0040] Moreover, the fermentation broth flowing through the second distribution pipe 230 can exchange heat with the heating component 400, so that the heating component 400 can heat the fermentation broth in the second distribution pipe 230, and then the heated fermentation broth can be input into the distiller 100, so that the fermentation broth can evaporate in the distiller 100 to form alcohol vapor.

[0041] Refer to Figure 1 , in this embodiment, valves (not shown in the figure) are provided at the connection points of the main inlet pipe 210, the first distribution pipe 220 and the second distribution pipe 230. The valves can connect the adjacent ends of the first distribution pipe 220 and the second distribution pipe 230, so that the fermentation broth in the distiller 100 can be circulated and heated successively through the first distribution pipe 220 and the second distribution pipe 230, so that the fermentation broth continuously evaporates to form alcohol vapor.

[0042] On the one hand, the staff can make the main inlet pipe 210 communicate with the first distribution pipe 220 and the second distribution pipe 230 successively through the valves. The first distribution pipe 220 can input relatively cold fermentation broth into the distiller 100. The second distribution pipe 230 can input relatively hot fermentation broth into the distiller 100.

[0043] On the other hand, the main inlet pipe 210 can communicate with the first distribution pipe 220 and the second distribution pipe 230 at the same time. Fermentation broths at different temperatures enter different positions of the distiller 100, which helps to better separate alcohol and flavor substances, so that the distillation system can flexibly adjust the distillation process and produce whiskies with different flavors.

[0044] In other aspects, when the fermentation broth in the tank body 110 reaches the preset capacity, the staff can control the valve to disconnect the main inlet pipe 210 and connect the first distribution pipe 220 and the second distribution pipe 230, so that the fermentation broth in the distillation space can enter the second distribution pipe 230 through the first distribution pipe 220. The fermentation broth in the second distribution pipe 230 is heated by the heating component 400 and then input into the distillation space, so as to realize the circulating heating and distillation of the fermentation broth in the tank body 110. This inlet component 200 can ensure the distillation efficiency of the fermentation broth while reducing the complexity of the pipeline, facilitating the assembly, disassembly and maintenance of the distillation system, and reducing the production cost of the distillation system.

[0045] In some embodiments, the valve can be a three-way valve. The valve can be an electric valve.

[0046] In some other embodiments, valves can be respectively arranged on the main liquid inlet pipe 210, the first liquid distribution pipe 220 and the second liquid distribution pipe 230. Thus, the staff can adjust the on-off between the main liquid inlet pipe 210, the first liquid distribution pipe 220 and the second liquid distribution pipe 230 by adjusting the three valves.

[0047] Refer to Figure 1 , in this embodiment, the first liquid distribution pipe 220 communicates with the bottom of the distillation space, and the connection part of the second liquid distribution pipe 230 and the distillation space is higher than the connection part of the first liquid distribution pipe 220 and the distillation space.

[0048] On the one hand, it enables the fermentation broth input by the first liquid distribution pipe 220 and the second liquid distribution pipe 230 to form a stable temperature gradient, thereby improving the distillation efficiency. On the other hand, it is convenient for the distillate in the distillation space to form a heating cycle through the first liquid distribution pipe 220 and the second liquid distribution pipe 230 to continuously heat the fermentation broth.

[0049] Refer to Figure 1 , in this embodiment, the end of the second liquid distribution pipe 230 facing away from the main liquid inlet pipe 210 extends into the distillation space to form a liquid spraying part 231. A plurality of liquid outlets are formed on the liquid spraying part 231, so that the fermentation broth is evenly sprayed into the distillation space, thereby effectively improving the evaporation efficiency of the fermentation broth.

[0050] In some embodiments, the liquid spraying part 231 extends along the horizontal direction and crosses the center line of the tank body 110, so as to facilitate the fermentation broth in the liquid spraying part 231 to be evenly sprayed into the distillation space and effectively improve the evaporation efficiency of the fermentation broth.

[0051] In some embodiments, the liquid spraying part 231 can be in a net shape, and the net-shaped liquid spraying part 231 extends along the horizontal direction. The liquid spraying part 231 includes a plurality of liquid outlets, and the plurality of liquid spraying ports are evenly arranged on the liquid spraying part 231. The liquid spraying part 231 includes a liquid inlet. The liquid spraying part 231 is fixedly connected to the second liquid distribution pipe 230 so that the liquid spraying part 231 and the second liquid distribution pipe 230 form an integral body. The fermentation broth in the second liquid distribution pipe 230 can enter the liquid spraying part 231 through the liquid inlet of the liquid spraying part 231 and then be evenly sprayed into the distillation space through the plurality of liquid outlets.

[0052] Refer to Figure 1 , in this embodiment, the liquid inlet assembly 200 further includes a liquid inlet pump 240. The liquid inlet pump 240 is arranged on the second liquid distribution pipe 230 and is located outside the distiller 100, so that the liquid inlet pump 240 can provide power for the fermentation broth in the second liquid distribution pipe 230, so that the fermentation broth can be pumped into the distiller 100.

[0053] When the fermented liquid in the distillation space is circulated and heated through the first liquid separation pipe 220 and the second liquid separation pipe 230, the liquid inlet pump 240 can provide power for the fermented liquid to improve the evaporation efficiency of the fermented liquid.

[0054] Refer to Figure 1 , in this embodiment, the distillation system further includes a preheating device 300. The preheating device 300 is arranged on the main liquid inlet pipe 210 to preheat the fermented liquid, thereby effectively improving the evaporation efficiency of the fermented liquid and the production efficiency of the distillation system.

[0055] In some embodiments, the preheating device 300 can be a plate heat exchanger, a double-pipe heat exchanger, a spiral plate heat exchanger, a shell-and-tube heat exchanger, etc., so that the fermented liquid in the main liquid inlet pipe 210 can be preheated by an external heat source.

[0056] Refer to Figure 1 , in this embodiment, the distillation system further includes a heating assembly 400. The heating assembly 400 can be connected to the second liquid separation pipe 230 to heat the fermented liquid in the second liquid separation pipe 230.

[0057] The heating assembly 400 includes a first heating pipe 410, a circulation heat exchanger 420, and a second heating pipe 430 that are connected in sequence. The first heating pipe 410 is used to input a heat transfer medium into the circulation heat exchanger 420. The circulation heat exchanger 420 is connected to the liquid inlet assembly 200, and the heat transfer medium exchanges heat with the fermentation heat to boil the fermented liquid. The second heating pipe 430 is used to discharge the heat transfer medium after heat exchange.

[0058] When the main liquid inlet pipe 210 inputs the fermented liquid into the distiller 100 through the first liquid separation pipe 220 and the second liquid separation pipe 230, the circulation heat exchanger 420 can be turned on to heat the fermented liquid in the second liquid separation pipe 230 and improve the evaporation efficiency of the fermented liquid.

[0059] When the fermented liquid in the distiller 100 circulates through the first liquid separation pipe 220 and the second liquid separation pipe 230, the circulation heater is used to heat the fermented liquid in the second liquid separation pipe 230.

[0060] In some embodiments, the heat transfer medium can be high-temperature water vapor. The high-temperature steam enters the circulation heat exchanger 420 through the first heating pipe 410 and exchanges heat with the fermented liquid, causing the fermented liquid to heat up and boil, and the high-temperature water vapor condenses to form condensed water. The condensed water after heat exchange in the circulation heat exchanger 420 is then discharged to the outside through the second heating pipe 430.

[0061] In some embodiments, the circulation heat exchanger 420 can be a plate heat exchanger, a double-pipe heat exchanger, a shell-and-tube heat exchanger, etc., so that the high-temperature steam can exchange heat with the fermented liquid.

[0062] Refer toFigure 1 , in this embodiment, the distillation system further includes an energy recovery component 500. A refrigerant flows through the energy recovery component 500. The refrigerant can exchange heat with the alcohol vapor to condense the alcohol vapor to form liquor. And after absorbing heat, the refrigerant can be heated up to boil the fermentation broth.

[0063] The energy recovery component 500 includes a condenser 510, a flash tank 520, and a mechanical pressurizer 530 that are connected in sequence. The condenser 510 is connected to the Lyne arm 130 so that the alcohol vapor in the Lyne arm 130 enters the condenser 510. The condenser 510 can cool down the alcohol vapor to condense the alcohol vapor to form liquor and output it. The condensed water in the condenser 510 can absorb heat to form a high-temperature liquid.

[0064] The flash tank 520 is located downstream of the condenser 510 and is connected to the condenser 510. The flash tank 520 can receive the high-temperature liquid output by the condenser 510 and flash the high-temperature liquid to form flash steam.

[0065] The mechanical pressurizer 530 is located downstream of the flash tank 520 and is connected to the upper end of the flash tank 520 so that the flash steam in the flash tank 520 can be input into the mechanical pressurizer 530. The mechanical pressurizer 530 can pressurize the flash steam so that the flash steam is pressurized and heated up to form high-temperature steam under a high-pressure environment. The high-temperature steam output by the mechanical pressurizer 530 exchanges heat with the fermentation broth in the second liquid separation tube 230 to realize the reuse of the waste heat in the alcohol vapor and improve the energy utilization efficiency of the distillation system.

[0066] In some embodiments, the condenser 510 can be a shell-and-tube condenser 510, a double-pipe condenser 510, a plate condenser 510, etc., as long as it can cool the alcohol vapor into liquor.

[0067] In some other embodiments, the refrigerant water inlet of the condenser 510 is connected to the second heating tube 430 of the heating component 400 so that the condensed water output by the second heating tube 430 can flow into the refrigerator. In some other embodiments, the refrigerant water inlet of the condenser 510 can also be connected to an external refrigeration source so that the refrigerant in the external refrigeration source can flow into the condenser 510 to exchange heat with the alcohol vapor.

[0068] In some embodiments, the structure of the flash tank 520 is set with reference to the structure of the flash tank 520 in the related art so that the flash tank 520 can flash the volatile components in the liquid to form steam by quickly reducing the pressure. Flashing is instantaneous evaporation.

[0069] Refer to Figure 1, in this embodiment, the energy recovery component 500 further includes a reflux pipe 521. The reflux pipe 521 communicates with the bottom of the flash tank 520 and the condenser 510, and is used to transport the high-temperature liquid in the flash tank 520 back to the condenser 510 for continuous heating. When the flash tank 520 flashes the high-temperature liquid, part of the liquid flashes to form flash steam, and the other part of the liquid flows back to the condenser 510 through the reflux pipe 521. The part of the high-temperature liquid flowing back to the condenser 510 can continue to exchange heat with the alcohol steam, so that the high-temperature liquid continues to heat up to reach the flashing standard of the flash evaporator.

[0070] In this embodiment, a hot water circulation pump 522 is provided on the reflux pipe 521 to pump the high-temperature liquid in the flash tank 520 into the condenser 510, thereby improving the condensation efficiency of the high-temperature liquid.

[0071] In this embodiment, the mechanical pressurizer 530 can recompress the low-temperature and low-pressure steam to increase its temperature and pressure, and then use the steam with increased temperature as a heat source to exchange heat with the fermentation broth, thereby realizing the recycling of energy.

[0072] The high-temperature steam output by the mechanical pressurizer 530 can reach the temperature for boiling the fermentation broth, thereby being able to adjust the evaporation efficiency of the fermentation broth, adjust the components in the alcohol steam, and ensure the taste and flavor of the liquor.

[0073] Refer to Figure 1 , in this embodiment, the output port of the mechanical pressurizer 530 is communicated with the first heating pipe 410, so that the high-temperature steam is input into the first heating pipe 410 and mixed with the heat transfer medium, and then the mixture exchanges heat with the fermentation broth in the second liquid separation pipe 230 through the circulation heat exchanger 420.

[0074] In some embodiments, the mechanical pressurizer 530 has a suction function. The mechanical pressurizer 530 is connected to the flash tank 520 to be able to absorb the gas in the flash tank 520 and reduce the pressure in the flash tank 520. The reduction of the pressure in the flash tank 520 can effectively reduce the boiling point when the liquid flashes, so that more high-temperature liquid can flash to form flash steam, and thus the mechanical pressurizer 530 can pressurize more flash steam to form more high-temperature steam to heat the fermentation broth.

[0075] In this embodiment, the distiller 100, the liquid inlet component 200, the heating component 400, and the energy recovery component 500 form a distillation subsystem. The distillation system includes multiple distillation subsystems, and the liquid inlet of the downstream liquid inlet component 200 is communicated with the liquid outlet of the upstream distiller 100.

[0076] Refer to Figure 1, in this embodiment, the distillation system further includes a control module (not shown in the figure), and the control module can be electrically connected to the valve, the liquid inlet pump 240, the preheating device 300, the circulation heater 420, the condenser 510, the flash tank 520, the hot water circulation pump 522, the mechanical pressurizer 530 and their related structures, so as to control the start and stop, the adjustment of operating parameters and the status monitoring of the valve, the liquid inlet pump 240, the preheating device 300, the circulation heater 420, the condenser 510, the flash tank 520, the hot water circulation pump 522 and the mechanical pressurizer 530 and their related structures, thereby facilitating the operation of the staff and improving the working efficiency and convenience of the distillation system.

[0077] In some embodiments, the distillation system further includes structures such as a pressure gauge and a thermometer, which are respectively arranged at each pipeline and each device in the distillation system, so as to facilitate the staff to detect the working status of the distillation system in real time.

[0078] Refer to Figure 1 , this application provides a whisky distillation system. When the whisky distillation system is in use, the fermented liquid is preheated first, and then the preheated fermented liquid is input into the first liquid separation pipe 220 and the second liquid separation pipe 230 through the main liquid inlet pipe 210.

[0079] The fermented liquid in the first liquid separation pipe 220 and the second liquid separation pipe 230 is directly input into the distillation space of the tank body 110.

[0080] When the fermented liquid in the distillation space reaches the preset capacity, the main liquid inlet pipe 210 is disconnected, and the liquid inlet pump 240 is started, so that the fermented liquid in the distillation space is sequentially input back into the distillation space through the first liquid separation pipe 220 and the second liquid separation pipe 230. And when passing through the second liquid separation pipe 230, the circulation heater can heat the fermented liquid in the second liquid separation pipe 230, so that the fermented liquid evaporated after being input back into the distillation space forms alcohol vapor.

[0081] The alcohol vapor flows upward in the tank body 110, and after passing through the swan neck 120 and the lyne arm 130, it is input into the condenser 510. The condenser 510 can make the refrigerant exchange heat with the alcohol vapor, so that the alcohol vapor condenses to form whisky liquid, and the refrigerant is heated to form a high-temperature liquid.

[0082] In order to facilitate the use of the heat in the high-temperature liquid, the high-temperature liquid is input into the flash tank 520 to flash and form flash vapor, and the flash vapor is processed by the mechanical pressurizer 530 to form high-temperature steam, and the high-temperature steam can exchange heat with the fermented liquid.

[0083] After high-temperature steam is formed, it is input into the first heating pipe 410 and mixed with the heat transfer medium to heat the fermentation broth in the second liquid separation tank through the circulation heat exchanger 420, so that the fermentation broth is heated and evaporated, realizing the reuse of the heat in the alcohol steam, improving the energy utilization efficiency of the distillation system, reducing the production cost of the distillation system, and improving the production efficiency of the liquor.

[0084] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary terms, rather than restrictive terms. Since the present application can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
