Description

Technical Field

[0001] The present invention relates to the technical field of winemaking, and in particular to a distillation and fermentation coordinated production system and a production method thereof. Background Art

[0002] The formation of the sauce-flavored style of Maotai-flavor liquor is inseparable from the stacking fermentation process. For example, in the article "A Brief Introduction to the Production Process and Key Process Principles of Maotai-flavor Liquor": The mash contains a large number of aroma-producing microorganisms. During the stacking process, the microorganisms grow and reproduce in the saccharification pile to form Maotai-flavor flavor components and flavor precursors. However, there are not many technical studies on high-temperature stacking fermentation, and the focus is mainly on the study of microbial changes in stacking fermentation. For example, the study "The Change Law of Microbial Population during the Stacking of Mash" found that there are more bacterial species than fungal species during the stacking fermentation process. There are very few types of microorganisms in the stacked mash during the sanding period. The number of microbial species begins to increase gradually in the rough sand stage, and the number of microbial species is the richest during the second round of stacking; according to the article "Research on the Change Trend of Yeast in the Stacking Process of Maotai-flavor Liquor": The stacking process is an important period for various yeasts, especially brewing yeast, to be inoculated on the mash.

[0003] CN115305165A discloses a spatial temperature-controlled solid-state liquor fermentation system, comprising a fermentation tank, which comprises a tank body and a temperature-controlled heat exchange tube rotatably installed inside the tank body; a temperature-controlled liquid inlet pipe, which is arranged on one side of the fermentation tank; a temperature-controlled liquid outlet pipe, which is arranged on the other side of the fermentation tank; and two groups of sealing adapters, one group of which is installed between the temperature-controlled liquid inlet pipe and the temperature-controlled heat exchange tube, and the other group is installed between the temperature-controlled liquid outlet pipe and the temperature-controlled heat exchange tube.

[0004] Traditional Maotai-flavor liquor brewing workshops discharge the high-temperature gas produced by distillation directly into the air without treatment and recycling. The discharge of high-temperature steam not only wastes energy, but also causes the local temperature to rise. Therefore, how to recycle the high-temperature steam in the workshop for reuse and how to achieve green brewing that is both energy-saving and environmentally friendly are issues that liquor companies should think about.

[0005] The traditional Maotai-flavor liquor has a production cycle of one year, which involves two feedings, nine steamings, eight fermentation piles, and seven wine extractions. Generally, the fermentation is done on the Double Ninth Festival. The first few rounds of fermentation piles are in winter. The winter climate inhibits the growth of microorganisms, which can easily lead to uneven or slow heating of the piles, resulting in long fermentation times (up to 8 to 10 days), thus extending the production time and even affecting the wine yield. Therefore, how to ensure the stable and uniform heating of the mash during the stacking process is an urgent problem to be solved in the current stacking fermentation.

[0006] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, when the applicant made this invention, a large number of documents and patents were studied, but due to space limitations, all details and content were not listed in detail.

On the contrary, this invention already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a distillation-fermentation collaborative production system and its production method, aiming to solve at least one or more technical problems existing in the prior art.

[0018] Preferably, the intake order of several fermentation subunits is carried out in descending order of their respective corresponding intake temperatures.

[0019] Preferably, the condensation rate of the distillation gas in the condensation device refers to the ratio of the amount of the liquid condensed from the distillation gas collected in the condensation device per unit time to the amount of the distillation gas passing through the condensation device per unit time.

[0020] Preferably, the present invention also relates to a method for collaborative production of distillation and fermentation, which may include the following steps:

[0025] Adjusting the ratio of the first gas flow rate between the distillation device and the fermentation device and the second gas flow rate between the distillation device and the condensation device based on the condensation rate of the distillation gas in the condensation device.

[0026] The present invention provides a method and a device for insulating the piled area of fermented grains materials under the condition of too low temperature in winter, effectively solving the problem that the fermented grains of soy sauce wine do not heat up due to too low temperature in winter and improving the efficiency of piled fermentation. By reusing the residual gas generated from the distillation of fermented grains for insulating the piled area in the workshop in winter, the problems of energy waste and interference with the local ambient temperature are avoided, which is energy-saving and environment-friendly and makes a step towards green brewing. By setting up series-connected fermentation sub-units and a ventilation pipe with a heating function, on the basis of utilizing the heat of the residual distillation gas, it is ensured that each fermentation sub-unit can reach its respective required fermentation temperature, and compared with the existing unified heating of the workshop, the heating cost is significantly reduced; more importantly, the fermented materials contain various aromatic substances (such as esters) whose aromatic properties change with the fermentation temperature. Utilizing the secondary recycled residual distillation gas of fermented grains to keep the temperature of each fermentation sub-unit in the fermentation device at an appropriate fermentation temperature helps to ensure the stability of various aromatic substances in the fermented materials under different processes and batches, thus ensuring the stability of the taste and flavor of each batch of wine products. In addition, by monitoring the amount of distillation gas and the amount of condensate, the condensation rate of the distillation gas is determined, the connection state between the distillation device and the fermentation device is adjusted based on the condensation rate, and the flow path of the distillation gas is adjusted according to the distillation state and the distillation process, so as to introduce the residual distillation gas into the fermentation device at the stage when the distillation process is basically completed. At the same time, the gas condensed by the condensation device can also be introduced into the fermentation device, and the heat in this gas can also be utilized. More importantly, the gas from the condensation device can be used to adjust the gas flow rate in the ventilation pipe and purge the condensate in the ventilation pipe, further improving the operation efficiency of this co-production system.

In particular, the on-off connection of the distillation device 100 with the condensation device 200 and the fermentation device 300 is performed based on the material state in the distillation device 100 and / or the condensation device 200.

[0036] According to a preferred embodiment, in the present invention, the distillation device 100 is used to heat the fermented grains material to generate distillation gas containing alcohol. In particular, the distillation device 100 may include equipment used for distillation and impurity removal in the liquor brewing process, such as a distillation retort barrel or a wine retort bottom pot.

[0037] Further, the distillation device 100 may also include a fermented grains feeding device, a material distributor, a steam distributor, a discharge device, etc. Specifically, the fermented grains feeding device, the material distributor, the steam distributor, and the discharge device may be arranged in the distillation retort barrel from top to bottom.

[0038] According to a preferred embodiment, the fermented grains feeding device may include a feeder, which is used to convey the fermented grains material to the material distributor. Specifically, the material distributor may include a distribution device and a distribution screen plate, wherein the distribution device is used to evenly spread the fermented grains material on the distribution screen plate. Further, the distribution screen plate is used to evenly distribute the fermented grains material in the distillation retort barrel. It should be understood that the distribution device and the distribution screen plate are relatively mature technologies, and their specific structures can be referred to the prior art. The present invention has no intention of improving them, and is only described as a non-limiting example.

[0039] According to a preferred embodiment, the steam distributor performs a distillation operation on the fermented grains layer formed by the fermented grains material in the distillation retort through steam to form a distillation gas containing alcohol / wine.

[0041] According to a preferred embodiment, the condensing device 200 may be a condenser, which is used to condense the distilled gas containing alcohol to produce liquid containing water, alcohol and / or some trace aroma components in batches according to the difference in boiling points of various substances in the distilled gas. Specifically, the condensing device 200 may be an evaporative condenser, a water-cooled condenser, an air-cooled condenser, etc.

[0042] According to a preferred embodiment, Figure 2 As shown, the discharge end of the condensing device 200 can be connected to the wine storage device 500 through a pipeline. As a non-limiting example, the condensing device 200 can be a water-cooled condenser, which has a flow regulating valve for regulating the flow of cooling water flowing into the condensing device 200. Further, the condensing device 200 can also include a gas regulating valve and a pump component. The gas regulating valve and the pump component can be used to adjust the top pressure in the distillation device 100. Specifically, the gas regulating valve can be opened when the top pressure in the distillation device 100 reaches a threshold value (such as ultra-low pressure), and the set pressure is maintained by absorbing external air to prevent accidents. The pump component can be a vertical multi-stage centrifugal pump, a horizontal multi-stage centrifugal pump or a vertical single-stage centrifugal pump that can be pressurized and can also form a vacuum negative pressure. By adjusting the pump component, it can be used to achieve the operation of reduced pressure distillation.

[0043] According to a preferred embodiment, the fermentation device 300 may be a fermentation tank for fermented mash or a fermentation device for fermented mash accumulation. Specifically, the fermentation device 300 forms sauce-flavored flavor components and flavor precursors in the fermented mash material by inoculating microorganisms. Specifically, Figure 1 As shown, the fermentation device 300 may include several fermentation subunits 301 connected in series. Adjacent fermentation subunits 301 may be connected via ventilation pipes 302. In particular, the ventilation pipes 302 may be used to heat or cool the distilled gas therein so that each fermentation subunit 301 reaches its own preset intake temperature.

[0044] According to a preferred embodiment, the monitoring device 400 is used to monitor at least one process or state parameter during the operation of the distillation device 100, the condensation device 200 and the fermentation device 300, such as the material inlet and outlet speed, temperature and steam pressure of the distillation device 100, the inlet and outlet gas flow rate, temperature and condensate content of the condensation device 200, and the fermentation temperature of the fermentation device 300.

[0045] According to a preferred embodiment, the monitoring device 400 may at least include a gas flow monitoring module 401, a liquid volume monitoring module 402 and / or a temperature monitoring module 403 and a controller. The gas flow monitoring module 401, the liquid volume monitoring module 402 and / or the temperature monitoring module 403 are all electrically connected to the controller.

[0046] According to a preferred embodiment, the gas flow monitoring module 401 may include a plurality of gas flow sensors, which may be respectively arranged in any one or all of the distillation device 100, the condensation device 200 and the fermentation device 300. Specifically, the gas flow sensor associated with the distillation device 100 may be arranged at the steam outlet of the distillation device 100 to monitor the flow rate of the steam produced by the distillation device 100 in real time. Further, the gas flow sensor associated with the condensation device 200 may be arranged at the steam inlet and steam outlet of the condensation device 200 to monitor the flow rate of the steam entering and exiting the condensation device 200 in real time.

[0047] According to a preferred embodiment, the temperature monitoring module 403 may include a plurality of temperature sensors, which may be respectively arranged in any one or all of the distillation device 100, the condensation device 200 and the fermentation device 300. Specifically, at least two temperature sensors associated with the distillation device 100 (such as a distillation retort) may be arranged, at least one of which may be arranged at the fermented grains layer of the distillation retort to monitor the temperature of the fermented grains layer in real time, and at least another one of which may be arranged at the top vapor outlet of the distillation retort to monitor the upper vapor temperature of the distillation retort in real time. In particular, the temperature of the fermented grains layer and / or the upper vapor temperature may reflect the alcohol content in the vapor, and thus may serve as a data guide for the distillation process.

[0048] According to a preferred embodiment, at least two temperature sensors associated with the condensation device 200 can be arranged, at least one of which can be arranged at the vapor inlet of the condensation device 200 for real-time monitoring of the inlet temperature of the vapor entering the condensation device 200, and at least one other of which can be arranged at the vapor outlet of the condensation device 200 for real-time monitoring of the exhaust temperature of the vapor discharged from the condensation device 200. Further, the temperature sensors associated with the condensation device 200 may further include a plurality of temperature sensors for real-time monitoring of the inlet temperature of the cooling water, the outlet temperature of the cooling water, and the condensate temperature.

[0049] According to a preferred embodiment, the temperature sensors associated with the fermentation device 300 can be one or more, and these temperature sensors can be arranged at the inlets of the respective fermentation subunits 301 for real-time monitoring of the inlet temperature of each fermentation subunit 301. Further, the temperature sensors arranged in the fermentation device 300 can also be used for real-time monitoring of the temperature during the fermentation process of the fermented grains in the fermentation device 300. The controller can judge the fermentation degree, fermentation quality, and fermentation effect of the fermented grains according to the relationship between the temperature during the fermentation process of the fermented grains and time. Specifically, the controller can adjust the working state of the fermentation device 300 according to the temperature during the fermentation process of the fermented grains in combination with the water content in the fermented grains when entering the fermentation pit, the ratio of grains to fermented grains, and other parameters, so as to improve the fermentation degree, fermentation quality, and fermentation effect of the fermented grains.

[0050] According to a preferred embodiment, the liquid volume monitoring module 402 can include a plurality of liquid volume sensors or liquid level sensors, and these liquid volume sensors or liquid sensors can be respectively arranged in any one or all of the distillation device 100, the condensation device 200, and the fermentation device 300. Specifically, the liquid volume sensors or liquid level sensors associated with the condensation device 200 can be used for real-time monitoring of the content of the condensate in the condensation device 200, and this content usually reflects the alcohol content. Further, the controller can determine the condensation rate of the condensation device 200 according to the content of the condensate in the condensation device 200 and the content of the distillation gas entering the condensation device 200. Thus, based on the condensation rate of the condensation device 200, the controller can switch the conduction state between the distillation device 100, the condensation device 200, and the fermentation device 300 to adjust the flow direction of the distillation gas.

[0051] According to a preferred embodiment, in the present invention, the condensation rate of the distilled gas in the condensing device 200 may be the ratio of the amount of liquid condensed from the distilled gas collected in the condensing device 200 per unit time to the amount of distilled gas passing through the condensing device 200 per unit time. In particular, the condensation rate of the condensing device 200 may characterize the degree of wine output, and when the condensation rate of the condensing device 200 is lower than a preset condensation rate threshold, it may generally indicate that the wine extraction has entered the end, at which time, the distilled gas that continues to be produced by the distillation device 100 contains almost no or only a small amount of alcohol, but is the residual high-temperature residual gas of the distillation of the remaining mash.

[0052] According to a preferred embodiment, in the present invention, when the condensation rate of the condensation device 200 is lower than a preset condensation rate threshold, the controller connects the distillation device 100 and the fermentation device 300 to introduce the high-temperature distillation residual gas subsequently produced by the distillation device 100 into the fermentation device 300, provide the fermentation temperature required by the fermentation device 300, and realize the recycling and reuse of the high-temperature exhaust gas produced by the distillation device 100.

[0053] According to a preferred embodiment, in the present invention, the monitoring device 400 may also include a feed monitoring module and a discharge monitoring module, and the feed monitoring module and the discharge monitoring module are electrically connected to the controller. Specifically, the feed monitoring module is used to monitor the feed speed of the fermented grains material delivered to the distillation device 100. The discharge monitoring module is used to monitor the removal speed of the fermented grains material output from the distillation device 100. The controller can control or adjust the feed amount and / or discharge amount of the fermented grains material according to the feed speed obtained by the feed monitoring module and the discharge speed obtained by the discharge monitoring module, so that the thickness of the fermented grains material layer in the distillation device 100 can be adjusted.

[0054] According to a preferred embodiment, the monitoring device 400 may also include a material level monitoring module, which is electrically connected to the controller. The material level monitoring module may be arranged in the distillation device 100, such as at the fermented grains material layer of the distillation retort, and is used to monitor the thickness of the fermented grains material layer in real time, so that the controller can drive the feeding device to adjust the feeding speed of the fermented grains material and the discharging device to adjust the discharging speed of the fermented grains material according to the real-time thickness of the fermented grains material layer, thereby real-time feedback to adjust the thickness of the fermented grains material layer. For example, when the real-time thickness of the fermented grains material layer obtained by the material level monitoring module is greater than or exceeds the standard range, the feeding device is driven to reduce the feeding speed of the fermented grains and / or the discharging device is driven to increase the discharging speed, thereby reducing the thickness of the fermented grains material layer.

[0055] According to a preferred embodiment, the monitoring device 400 may further include a vapor pressure sensor, which is electrically connected to the controller. Specifically, the vapor pressure sensor can be used to monitor the pressure of the vapor produced by the distillation device 100 in real time. In particular, based on the flow rate and pressure of the vapor produced by the distillation device 100, the controller can reasonably adjust the distillation process by controlling the opening and closing of the solenoid valve and adjusting the evaporation temperature.

[0056] According to a preferred embodiment, in the present invention, when the distillation device 100 is connected to the condensation device 200 and the condensation rate of the distillation gas in the condensation device 200 is lower than a preset condensation rate threshold, the distillation device 100 is connected to the fermentation device 300 so that the distillation gas enters the fermentation device 300. Further, the intake state of the distillation gas entering the fermentation device 300 is adjusted in association with the condensation rate of the condensation device 200.

[0057] Specifically, referring to Figure 3 , when the condensation rate of the distillation gas in the condensation device 200 is lower than the preset condensation rate threshold, the distillation device 100 is connected to the fermentation device 300 to supply the first distillation gas in the distillation device 100 to the fermentation device 300, thereby using the heat of the first distillation gas to provide the required fermentation temperature for the fermentation device 300. In particular, in the present invention, the first distillation gas may be the high-temperature residual vapor produced at the end of the distillation process, and this vapor contains almost no or only a small amount of alcohol.

[0058] According to a preferred embodiment, in the present invention, adjusting the intake state of the distillation gas entering the fermentation device 300 in association with the condensation rate of the condensation device 200 may include adjusting the intake amount of the first distillation gas entering the fermentation device 300 according to the condensation rate of the condensation device 200.

[0059] In particular, in the present invention, there is a first gas flow rate between the distillation device 100 and the fermentation device 300. There is a second gas flow rate between the distillation device 100 and the condensation device 200. Preferably, the first gas flow rate at which the distillation device 100 supplies the distillation gas to the fermentation device 300 and the second gas flow rate at which the distillation device 100 supplies the distillation gas to the condensation device 200 can be adjusted based on the condensation rate of the condensation device 200. More specifically, the ratio of the first gas flow rate and the second gas flow rate can be adjusted according to the condensation rate of the condensation device 200.

[0060] According to a preferred embodiment, the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300 can be determined according to the difference between the condensation rate of the condensation device 200 and a preset condensation rate threshold. Further, the first gas flow rate of the first distillation gas provided by the distillation device 100 to the fermentation device 300 can be increased in view of the decrease in the condensation rate of the condensation device 200. Specifically, in a state where the condensation rate of the condensation device 200 is lower than the preset condensation rate threshold, as the condensation rate decreases, the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300 is increased, so that more high-temperature residual vapor is led to the fermentation device 300, thereby improving the recovery and utilization of the high-temperature waste gas produced by the distillation device 100 and avoiding waste of energy. In particular, the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300 can be achieved by adjusting the pipe opening degree, the output power of the gas pumping component, or other common methods. On the other hand, while the condensation rate of the condensation device 200 decreases, the second gas flow rate of the distillation gas introduced from the distillation device 100 into the condensation device 200 can be reduced, so as to adjust the supply ratio of the distillation gas between the fermentation device 300 and the condensation device 200 according to the change in the condensation rate of the condensation device 200.

[0061] According to a preferred embodiment, the adjustment rate of the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300 and / or the second gas flow rate of the distillation gas introduced from the distillation device 100 into the condensation device 200 can be adjusted based on the change rate of the condensation rate of the condensation device 200. Specifically, if the decrease rate of the condensation rate of the condensation device 200 increases, the supply rate of the first distillation gas produced by the distillation device 100 is correspondingly increased. On the other hand, if the decrease rate of the condensation rate of the condensation device 200 increases, the supply rate of the distillation gas input from the distillation device 100 to the condensation device 200 is correspondingly slowed down.

[0062] According to a preferred embodiment, as Figure 1 shown, the fermentation device 300 may include a plurality of fermentation subunits 301 connected in series through a ventilation pipe 302. The ventilation pipe 302 is arranged to be able to heat or cool the distillation gas therein (such as Figure 3 the first distillation gas shown), so that each fermentation subunit 301 reaches a corresponding preset intake air temperature. Specifically, each ventilation pipe 302 may be correspondingly connected with a heater and / or a cooler (not shown in the figure), and the temperature of the distillation gas in each ventilation pipe 302 can be adjusted through the heater and / or the cooler. Or it can be understood that the temperature of the distillation gas in the ventilation pipe 302 can also be adjusted by other common methods.

[0063] According to a preferred embodiment, in the present invention, the inlet temperature of the distillation gas entering each fermentation subunit 301 can be determined and adjusted according to the amount of the fermentation material contained in the corresponding fermentation subunit 301 and / or the fermentation stage of the fermentation material. Specifically, the inlet temperature of the distillation gas entering each fermentation subunit 301 can be adaptively increased as the amount of the fermentation material contained in the fermentation subunit 301 increases. Further, different fermentation stages of the fermentation material have different fermentation temperature requirements. By monitoring the generation and concentration of target substances (such as alcohols, aldehydes, and / or esters) in the fermentation device 300 by the monitoring device 400, the fermentation stage of the fermentation material can be determined, so that the inlet temperature of the distillation gas entering each fermentation subunit 301 can be adjusted according to the fermentation stage of the fermentation material.

[0064] According to a preferred embodiment, the inlet temperature of the distillation gas entering each fermentation subunit 301 can also be determined and adjusted according to the first gas flow rate of the distillation gas. Specifically, the gas flow rate of the distillation gas entering each fermentation subunit 301 will affect the fermentation temperature of the fermentation subunit 301 and thus affect the fermentation process of the fermentation material. In view of this, according to the fermentation temperature requirements of different fermentation stages of the fermentation material, when the first gas flow rate of the distillation gas is relatively low, the temperature of the distillation gas in the ventilation pipe 302 can be increased to make up for the temperature loss caused by insufficient vapor flow rate. On the other hand, when the first gas flow rate of the distillation gas is relatively high, the temperature of the distillation gas in the ventilation pipe 302 can be reduced to reduce the negative impact that the relatively excessive high-temperature steam may have on the fermentation process of the fermentation material.

[0065] According to a preferred embodiment, in the present invention, the inlet sequence of several fermentation subunits 301 can be executed in descending order of their respective corresponding inlet temperatures. In other words, the first distillation gas produced by the distillation device 100 can be preferentially introduced into the fermentation subunit 301 with a higher inlet temperature requirement. In view of this, the residual heat of the first distillation gas can be preferentially utilized by the fermentation subunit 301 with a higher inlet temperature requirement, and the loss of unnecessary energy caused by too large a temperature difference can be reduced. For example, introducing the relatively high-temperature first distillation gas into the fermentation subunit 301 with a lower inlet temperature requirement involves reducing the inlet temperature of the first distillation gas to the required inlet temperature, and the heat exchange occurring in this process may involve energy loss and consumption.

[0066] According to a preferred embodiment, in order to improve the heating efficiency of the distillation gas on the fermentation subunit 301 and the fermentation material therein, refer to Figure 3, in the present invention, the inner wall of the ventilation pipe 302 for connecting each fermentation subunit 301 is configured with several protrusions that form an angle β with the inner wall of the ventilation pipe 302. Specifically, the protrusions on the inner wall of the ventilation pipe 302 slow down the flow rate of the distillation gas to a certain extent, and the relatively high-speed distillation gas flowing in from the upstream mixes with the distillation gas at the protrusions, so that the protrusions allow the first distillation gas flowing in to easily form irregular turbulence in the ventilation pipe 302, and even vortices of different sizes appear. In particular, the turbulence or vortex phenomenon of the distillation gas tends to accelerate the homogeneous mixing degree of the distillation gas in the ventilation pipe 302, making the heat carried by the distillation gas more evenly distributed, and thus can improve the heating efficiency of the distillation gas for the fermentation subunit 301.

[0067] According to a preferred embodiment, in order to further adjust or improve the homogeneous mixing degree of the distillation gas in the ventilation pipe 302, in the present invention, the air outlet of the condensation device 200 can be operably connected to the ventilation pipe 302 through a pipeline, so that the second condensed distillation gas in the condensation device 200 can enter the ventilation pipe 302 in a manner that forms an angle α with the flow direction of the first distillation gas in the ventilation pipe 302, thereby adjusting the gas flow rate in the ventilation pipe 302 and purging the condensate in the ventilation pipe 302.

[0068] Specifically, referring to Figure 3 , it can be arranged in such a way that the pipeline connecting the condensation device 200 to the fermentation device 300 and the ventilation pipe 302 between the distillation device 100 and the fermentation device 300 forms an angle α, so that there is an angle α between the second distillation gas transported by the condensation device 200 to the fermentation device 300 and the first distillation gas transported by the distillation device 100 to the fermentation device 300. Or, it can be arranged in such a way that the pipeline connecting the condensation device 200 to the fermentation subunit 301 and the ventilation pipe 302 between each fermentation subunit 301 forms an angle α, so that there is an angle α between the second distillation gas transported by the condensation device 200 to each fermentation subunit 301 and the first distillation gas transported by the distillation device 100 to the fermentation subunit 301.

[0069] According to a preferred embodiment, when the second distillation gas is introduced into the fermentation device 300 or each fermentation subunit 301 in a manner that forms an included angle α with the first distillation gas transported from the distillation device 100 to the fermentation device 300, the second distillation gas and the first distillation gas with different flow directions are mixed to easily generate turbulence. The formation of this turbulence is particularly obvious when there is a significant difference in the flow rates of the first distillation gas and the second distillation gas, thereby increasing the mixing degree of the first distillation gas and the second distillation gas, and further improving the homogeneous mixing degree of the distillation gas in the ventilation pipe 302. In addition, introducing the distillation gas produced by the condensation device 200 into the fermentation device 300 further increases the utilization rate of the waste gas heat, and based on the temperature and / or flow rate difference between the second distillation gas and the first distillation gas, it can also be used to adjust the intake temperature of the distillation gas entering each fermentation subunit 301 in the ventilation pipe 302. Thus, without additionally introducing or providing other energy outside the system, it not only meets the intake temperature requirements of each fermentation subunit 301, provides a suitable fermentation environment for the fermentation device 300, but also reduces the energy waste of the entire production system, reduces waste output and decreases the waste discharge amount, achieving the purpose of energy conservation, environmental protection and green brewing.

[0070] According to a preferred embodiment, in the present invention, the flow included angle α between the second distillation gas provided by the condensation device 200 and the first distillation gas provided by the distillation device 100 can be set in association with the included angle β corresponding to the protrusions provided on the inner wall of the ventilation pipe 302. In other words, in order to improve the turbulence degree or scale of the distillation gas in the ventilation pipe 302, the included angle α between the second distillation gas and the first distillation gas should be determined according to the included angle β corresponding to the protrusions provided on the inner wall of the ventilation pipe 302. Or, the included angle β corresponding to the protrusions provided on the inner wall of the ventilation pipe 302 can be set according to the included angle α between the second distillation gas and the first distillation gas. Specifically, the corresponding relationship between the included angle α and the included angle β can be determined by those skilled in the art based on pipe fluid mechanics by testing the heat distribution state of the distillation gas in the ventilation pipe 302. More specifically, when the included angle β is determined, different included angles α cause the distillation gas in the ventilation pipe 302 to form different degrees of turbulence, so that the distillation gas in the ventilation pipe 302 has different homogeneous mixing degrees. Or, when the included angle α is determined, the protrusions provided on the inner wall of the ventilation pipe 302 have different effects on the homogeneous mixing state of the distillation gas in the ventilation pipe 302 due to different included angles β.

[0077] According to a preferred embodiment, adjusting the intake state of the distillation gas entering the fermentation device 300 in association with the condensation rate of the distillation gas includes adjusting the intake volume of the distillation gas entering the fermentation device 300. Specifically, the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300 can increase based on the decrease in the condensation rate of the distillation gas in the condensation device 200. More specifically, in a state where the condensation rate of the distillation gas in the condensation device 200 is lower than the preset condensation rate threshold, as the condensation rate decreases, increase the first gas flow rate of the first distillation gas introduced from the distillation device 100 into the fermentation device 300.

[0078] According to a preferred embodiment, when the condensation rate of the condensation device 200 decreases, the second gas flow rate of the distillation gas introduced from the distillation device 100 into the condensation device 200 can be reduced.

[0079] According to a preferred embodiment, the distillation and fermentation co-production method of the present invention further includes adjusting the intake temperature of the distillation gas entering each fermentation subunit 301 according to the amount of the fermented material contained in the corresponding fermentation subunit 301, the fermentation stage of the fermented material, and / or the flow rate of the distillation gas.

[0080] According to a preferred embodiment, the distillation and fermentation co-production method of the present invention further includes determining the intake order of the first distillation gas produced by the distillation device 100 entering each fermentation subunit 301 according to the preset intake temperature corresponding to each fermentation subunit 301. More specifically, the intake order of several fermentation subunits 301 can be executed from high to low according to their corresponding intake temperatures.
