Description

Technical Field

[0001] The invention relates to the technical field of manufacturing automated equipment for liquor brewing, and in particular to an integrated system and method integrating a fermentation container and a distillation retort body. Background Art

[0002] In the process of liquor brewing, fermentation and distillation are indispensable process links. For the solid-state fermentation process, more and more companies use stainless steel fermentation boxes instead of brick cellars, ground tanks, etc. as fermentation containers. The fermentation box is equipped with a filter to filter the yellow water produced by fermentation. After the fermentation is completed, the yellow water in the mash is dripped out, the mash is poured out for mixing, and then the mash is distilled and the wine is extracted using a distillation system; the distillation system consists of a steamer barrel and matching bottom pots, condensers and other equipment, which can extract ethanol and aroma components from the mash. Considering that both fermentation and distillation require containers to hold the mash, and mash fermentation and distillation use different tank equipment to hold the mash, there are problems such as single form and function, large number of equipment, and large space occupied.

[0003] CN 114381352A discloses a solid-state fermented grains pressure-variable distillation system. The solid-state fermented grains pressure-variable distillation system comprises a distillation retort, a cooler, a temporary storage tank, a vacuum pump and a three-way exhaust valve. The cooler is connected to the vacuum pump through a vacuum pumping pipeline, a vacuum exhaust valve is arranged on the vacuum pumping pipeline, the cooler is provided with a wine vapor inlet and a liquid outlet, the wine vapor inlet is connected to the distillation retort through a pipeline, a regulating valve is arranged on the pipeline connecting the wine vapor inlet and the distillation retort, the inlet end of the temporary storage tank is connected to the liquid outlet, the three-way exhaust valve is arranged at the outlet end of the temporary storage tank, the first end of the three-way exhaust valve is connected to the temporary storage tank, the second end is connected to the vacuum pumping end of the vacuum pump, and the third end is connected to the atmospheric environment.

[0004] The solid-state fermented grains pressure-variable distillation system provided by the patent saves energy and improves the quality of wine during the winemaking process by virtue of its ability to independently select reduced pressure, positive pressure or normal pressure distillation modes according to the types of fermented grains in the upper, middle and lower layers of the distillation retort and the quality of the flowing wine. However, the position of the distillation retort in the patent is fixed at a specific position. This design lacks flexibility and limits the wide application of the distillation retort in various liquor brewing processes. The fixed position not only limits the layout optimization of the production line, but also makes it difficult to directly migrate the distillation retort to other production environments or use it in other brewing processes, increasing the complexity and cost of the operation. Secondly, in order to achieve the effective collection and treatment of wine vapor, the patent arranges a large number of intricate pipes. These pipes increase the footprint and installation difficulty of the system. In a limited production space, these pipes not only occupy valuable site resources, but may also hinder the overall layout of the production line, limiting the application scenarios of the system.

[0005] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides an integrated system and method integrating a fermentation container and a distillation retort body to solve at least part of the above-mentioned technical problems.

[0007] The present invention relates to an integrated system integrating a fermentation container and a distillation retort body, which comprises a fermentation unit, a distillation unit and an integrated tank body. The integrated tank body can be detachably connected to the fermentation unit, and after the integrated tank body completes the fermentation process of mash at the fermentation unit, it can be sent to a production area where the distillation unit is located with the help of a transfer device and complete the detachable connection with the distillation unit. A flip assembly is connected to the base of the distillation unit, and the flip assembly is connected to a retort cover through a delivery pipe. The flip assembly drives the delivery pipe to rotate by means of its hydraulic transmission mechanism, so as to drive the retort cover to perform opening and closing operations on the open top surface of the integrated tank body, wherein the delivery pipe can guide the wine vapor in the integrated tank body to a condenser connected to the flip assembly to obtain white wine.

[0008] The innovation of the present invention lies in that it breaks through the design limitations of traditional liquor brewing equipment, and realizes the seamless connection of the fermentation and distillation processes through a specially designed integrated tank body. This design is not common in the art, because it requires the integrated tank body to not only meet the needs of the fermentation unit, but also to adapt to the specific conditions of the distillation unit. Specifically, the integrated tank body of the present invention can be detachably connected to the fermentation unit and the distillation unit. This design makes the equipment assembly and disassembly simple, and is convenient for cleaning, maintenance and overhaul, thereby enhancing the reliability of the entire system. After the fermentation is completed, the integrated tank body can be directly transferred to the distillation unit, eliminating the complex material transfer steps in the traditional process and significantly shortening the production cycle. In addition, through the hydraulic transmission mechanism, the flip assembly can accurately control the opening and closing of the steamer cover, ensuring the safety and convenience of operation and reducing the errors of manual operation.

[0009] According to a preferred embodiment, the fermentation unit includes an openable and closable tank cover assembled at the top opening of the integrated tank body, and an elastic sealing gasket is embedded in the sealing groove on the inner edge of the tank cover. When the tank cover is closed, the sealing gasket forms a sealing layer at the edge of the opening of the integrated tank body in a pressurized manner. The tank cover and the integrated tank body are mechanically connected, and a gas management component is integrated on the tank cover to regulate the internal fermentation environment of the integrated tank body. An elastic sealing gasket is embedded in the sealing groove on the inner edge of the tank cover. This design allows the sealing gasket to be evenly pressurized when the tank cover is closed, forming a reliable sealing layer at the edge of the opening of the integrated tank body. This sealing layer effectively prevents the penetration of external air, moisture and microorganisms, and ensures the purity and stability of the fermentation environment. In addition, the provision of the gas management component also helps to optimize the fermentation process and improve the quality and yield of the fermentation product.

The mounting seat ensures the automatic docking and separation between the integrated tank body and the yellow water tank by guiding and positioning the several groups of docking interfaces provided at the bottom of the integrated tank body. The bottom or side wall of the yellow water tank is also equipped with a drain port to facilitate the discharge and treatment of the yellow water byproducts generated during the fermentation process. The design of matching the mounting seat with the interface at the bottom of the integrated tank body realizes the automatic docking and separation between the yellow water tank and the integrated tank body, which improves production efficiency, reduces the need for manual operation, and also reduces the error rate during operation. The several groups of docking interfaces provided at the bottom of the integrated tank body provide guiding and positioning functions, which ensure the accurate docking of the yellow water tank with the tank body, thereby ensuring the stability and reliability during the fermentation process.

[0011] According to a preferred embodiment, the base of the distillation unit includes a first frame and a second frame. The top of the first frame is open and directly connected to the bottom pot. A steam coil is arranged in the bottom pot to generate steam by heating the clean water in the bottom pot to distill the mash in the integrated tank body. The side wall and the bottom of the bottom pot are respectively provided with a water inlet pipe and a drain port to realize the supply and discharge of clean water. The base design of the distillation unit includes a first frame and a second frame. This structure allows the bottom pot to be directly connected to the integrated tank body, ensuring the effective transfer of heat energy. The configuration of the steam coil allows the bottom pot to be heated quickly and evenly, improving the distillation efficiency. The side wall and the bottom of the bottom pot are respectively provided with a water inlet pipe and a drain port. This design allows the winemaking operator to flexibly supply and discharge clean water according to the actual needs of the distillation process, ensuring the appropriate control of the water level of the bottom pot.

[0012] According to a preferred embodiment, the steamer cover is designed to be openable and closable, matching the top of the integrated tank body, and fixedly connected to the top of the tank body by bolts or buckles. An air outlet is provided on the top of the steamer cover to collect the wine vapor generated in the integrated tank body during the distillation process, and guide it to the condenser for condensation through the delivery pipe on the top of the second frame. The openable and closable design of the steamer cover allows the operator to open or close the steamer cover at any time according to the needs of the distillation process, so as to accurately control the distillation process. The air outlet on the top of the steamer cover is directly connected to the delivery pipe. This design helps to efficiently collect the wine vapor generated in the integrated tank body, reduce the escape of steam, and improve the distillation efficiency. The steam is guided to the condenser through the delivery pipe on the top of the second frame, which simplifies the condensation process, enables the steam after distillation to be quickly condensed, and reduces energy loss.

[0013] According to a preferred embodiment, the flip assembly includes an assembly platform, a support plate, a connecting piece, a delivery pipe, a bell mouth and a hydraulic transmission mechanism, wherein the assembly platform is arranged on the top of the second frame, and a gas through hole for the wine vapor to pass through is provided on the support plate installed on the top of the assembly platform, and the connecting piece is movably connected to the support plate and driven by the hydraulic transmission mechanism to drive the delivery pipe and the bell mouth located at the starting end of the delivery pipe to realize the opening and closing operation of the steamer cover. The integrated design of the flip assembly combines the assembly platform, the support plate, the connecting piece, the delivery pipe, the bell mouth and the hydraulic transmission mechanism to form a compact unit, which helps to reduce space occupation and improve the stability of the overall structure. The introduction of the hydraulic transmission mechanism allows the opening and closing operations of the steamer cover to be automated, reduces manual intervention, and improves operational efficiency and safety.

[0014] According to a preferred embodiment, the vertex position of the connecting member is kept stable and connected to the support plate, the delivery pipe and the steamer cover by three connecting members, wherein the first connecting member is arranged at the bell mouth of the connecting member closest to the starting end of the delivery pipe, the second connecting member is arranged at the end of the delivery pipe, and forms a rotatable interface with the air through hole on the support plate; the third connecting member is arranged at the highest vertex of the connecting member within the second frame range, and is rotatably connected to the hydraulic rod serving as a power source. The arrangement of the first connecting member and the second connecting member makes the connection between the delivery pipe and the connecting member both firm and flexible. This design allows the delivery pipe to be adjusted when necessary to adapt to different operating conditions. The third connecting member is directly connected to the hydraulic rod. This direct power transmission method can ensure the effective use of hydraulic power and achieve precise control of the opening and closing operations of the steamer cover.

[0015] According to a preferred embodiment, a water measuring pipe is arranged at the top of the steamer cover near the gas outlet, and the water measuring pipe is arranged along the extension direction of the conveying pipe, and penetrates into the steamer cover in a bent structure at its end. By arranging the outlet of the water measuring pipe at the top of the steamer cover near the gas outlet, after the mash is distilled, the water can be sprayed into the mash in a relatively uniform and comprehensive manner, thereby promoting the gelatinization of the starch material and further promoting the action of the enzyme.

[0016] According to a preferred embodiment, a level gauge that displays the height of the clean water level is provided on the side wall of the bottom pot, and the valve of the water inlet pipe can be linked with the level gauge through an automated control program, so that the valve can be automatically opened and closed according to the monitoring structure of the level gauge, and the water level in the bottom pot is maintained within a suitable range during the distillation process. By precisely controlling the water level, it is possible to ensure that there is enough water to generate steam, while avoiding overflow caused by too high a water level or the distillation efficiency being affected by too low a water level. The automated linkage between the valve of the water inlet pipe and the level gauge enables the system to automatically respond to changes in the water level without manual intervention. This automated operation reduces the need for manual monitoring, reduces labor intensity, and improves the convenience and accuracy of operation.

[0017] The present invention also relates to an integrated method of a fermentation container and a distillation retort, the method comprising the following steps:

[0018] The mash after drying and adding koji is loaded into the integrated tank, and the tank cover is closed for closed fermentation. A yellow water tank is provided under the integrated tank to collect the yellow water produced during the fermentation process;

[0019] The integrated tank body is transferred to the distillation area, and the opening and closing of the retort cover on the top of the integrated tank body is controlled by the flip assembly. After the distillation starts, the wine vapor enters the distillation condenser through the flip assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following is a detailed description with reference to the accompanying drawings.

[0027] Example 1

[0028] This embodiment provides an integrated system of a fermentation container and a distillation retort, including a fermentation unit 100, a distillation unit 200 and an integrated tank body 300. Figure 1 and Figure 2 As shown, the design of the integrated tank body 300 is intended to achieve rapid transfer between the fermentation unit 100 and the distillation unit 200, thereby forming a continuous process flow. In the fermentation unit 100, the integrated tank body 300 is used as a fermentation container, mainly for containing and fermenting the mash. During the fermentation process, the mash undergoes biological transformation in the tank body to generate the desired fermentation products. After the fermentation is completed, the integrated tank body 300 can be directly used as a distillation retort body to continue the distillation process without replacing other containers for mash filling. During the distillation stage, the steam distillation process is carried out by continuously heating the fermentation product, thereby effectively separating the desired components. At this time, the wine vapor generated by the heating of the mash in the tank body is cooled by the condenser and collected as distillate. The design of the integrated tank body 300 not only meets the operating requirements of two different process units, but also ensures that the mash remains stable throughout the process, avoiding contamination and product loss that may be caused by frequent transfers.

[0029] Preferably, if Figure 1 As shown, the fermentation unit 100 includes a tank cover 110 and a yellow water tank 120. The tank cover 110 is designed to be assembled at the top opening position of the integrated tank body 300, and is used to close the integrated tank body 300 to provide a suitable environment for the fermentation of mash; the yellow water tank 120 is designed to be directly connected to the bottom of the integrated tank body 300, and is used to collect the yellow water by-product produced during the fermentation process.

[0030] Preferably, if Figure 1 to Figure 3As shown, the shape of the tank cover 110 is designed to be circular or elliptical to seamlessly connect the precise opening size of the top of the integrated tank body 300 to ensure a tight fit in the structure. The sealing of the top opening of the integrated tank body 300 can be achieved with the help of a sealing gasket, which is made of a high-temperature resistant and corrosion-resistant elastic material and embedded in a special sealing groove on the inner edge of the tank cover 110. When the tank cover 110 is connected to the tank body by bolts or quick-locking buckles, the entire sealing gasket is subjected to uniform pressure everywhere, forming a reliable sealing layer that effectively prevents the penetration of external air, moisture and microorganisms. In addition, a special gas management component can be integrated on the tank cover 110, including a gas exchange valve and a respirator, which work in conjunction with the sealing gasket to ensure that the tank body maintains a high degree of sealing while achieving fine control of the internal gas environment. Specifically, the gas exchange valve effectively controls the release of carbon dioxide and the replenishment rate of oxygen by accurately adjusting its opening and closing amplitude and frequency to adapt to the needs of different fermentation stages. In addition, the surface of the tank cover 110 can also integrate a monitoring component used in conjunction with the gas management component, which can accurately measure key parameters such as gas composition, temperature, and pressure in the tank. Based on the preset fermentation process parameters, the system automatically adjusts the working mode of the gas exchange valve to achieve accurate management of the internal gas environment.

[0031] According to a preferred embodiment, a concentration detection sensor for measuring oxygen and carbon dioxide concentrations is also provided in the fermentation unit 100. The sensor for measuring oxygen concentration is, for example, a digital oxygen sensor (Melexis MLX90393), an oxygen sensor (Vaisala XC02), etc. The sensor for measuring carbon dioxide concentration is, for example, an infrared carbon dioxide sensor (Vaisala GMP251), a non-dispersive infrared sensor NDIR (Honeywell MH-Z19), etc.

[0032] The automatic control program of this embodiment is preferably implemented by a controller such as a PID controller. In the integrated system of this embodiment, the controller can receive various parameters collected by various sensors or monitoring devices in real time, such as oxygen concentration, carbon dioxide concentration, temperature, pressure and other parameters in the fermentation unit 100, and compare the collected actual value with the preset target value to calculate the error; according to the error, the control algorithm (such as the PID control algorithm) is used to calculate the required control signal, and further, the calculated control signal is sent to the actuator (such as the gas exchange valve) to adjust the opening and closing amplitude and frequency.

[0033] According to this embodiment, the controller is configured to perform the following operations:

[0034] 1. Calculate the change in oxygen concentration in the fermentation unit 100. The calculation equation for the change in oxygen concentration is as follows:

[0035]

[0036] in, is the oxygen concentration at time point t, in mg / L; k in is the flow constant of the gas exchange valve at time point t, which indicates the amount of oxygen entering through the gas exchange valve per unit volume per unit time when the gas exchange valve is opened; U(t) is the opening and closing amplitude of the gas exchange valve at time point t, which indicates the degree of valve opening; f(t) is the opening and closing frequency of the gas exchange valve at time point t, which indicates the number of times the valve is opened per unit time, in units of times / minute; d(t) is the time of each opening, which indicates the duration of each valve opening, in seconds; It is the oxygen consumption per unit volume per unit time at time point t, which indicates the rate at which yeast consumes oxygen during the fermentation process.

[0037] According to this embodiment, k in Preferably, it is obtained by experimental measurement, for example, by using a standard gas flow meter to measure, with the gas exchange valve fully opened to ensure that the external oxygen concentration is known and constant, and the gas flow meter is used to measure the volume V of oxygen entering through the gas exchange valve per unit time. in , unit is L / min. k in The calculation formula is as follows:

[0038]

[0039] Among them, V tank is the volume of the fermentation unit 100, in L.

[0040] k in It can also be obtained based on the basic equations of gas flow (such as Darcy's law or Bernoulli's equation) combined with the characteristic parameters of the gas exchange valve (such as aperture, length, etc.). The following is an example formula provided in this embodiment:

[0041]

[0042] Among them, Q in is the flow rate, in L / min; A is the cross-sectional area of ​​the gas exchange valve, in m 2 ; P is the pressure difference, the unit is Pa.

[0043] Here, the calculation equation for the change in oxygen concentration combines the opening and closing frequency and opening time of the gas exchange valve, while also taking into account the oxygen consumption rate.

[0044] According to the calculation equation of the oxygen concentration change of this embodiment, the amount of oxygen entering the fermentation unit 100 through the gas exchange valve per unit time is calculated as follows:

[0045] kin ·U(t)·f(t)·d(t)

[0046] 2. Calculate the change in carbon dioxide concentration in the fermentation unit 100. The calculation equation for the change in carbon dioxide concentration is as follows:

[0047]

[0048] in is the carbon dioxide concentration at time point t, in mg / L; k is the amount of carbon dioxide produced per unit volume per unit time at time point t, which is the rate of carbon dioxide produced by yeast metabolism during fermentation; out is the flow constant of the gas exchange valve at time point t, which indicates the amount of carbon dioxide discharged through the gas exchange valve per unit volume per unit time when the gas exchange valve is opened; U(t) is the opening and closing amplitude of the gas exchange valve at time point t, which indicates the degree of valve opening; f(t) is the opening and closing frequency of the gas exchange valve at time point t, which indicates the number of times the valve is opened per unit time, in times / minute; d(t) is the time of each opening, which indicates the duration of each valve opening, in seconds.

[0049] According to this embodiment, k out Preferably, it is obtained by experimental measurement, for example, using a standard gas flow meter to measure, fully open the gas exchange valve, ensure that the carbon dioxide concentration in the fermentation unit 100 is known and constant, and use the gas flow meter to measure the volume V of carbon dioxide discharged through the gas exchange valve per unit time. out , unit is L / min. k out The calculation formula is as follows:

[0050]

[0051] Among them, V tank is the volume of the fermentation unit 100, in L.

[0052] k out It can also be obtained based on the basic equations of gas flow (such as Darcy's law or Bernoulli's equation) combined with the characteristic parameters of the gas exchange valve (such as aperture, length, etc.). The following is an example formula provided in this embodiment:

[0054] Among them, Q out is the flow rate, in L / min; A is the cross-sectional area of ​​the gas exchange valve, in m 2 ; P is the pressure difference, the unit is Pa.

[0055] Here, the calculation equation for the change in carbon dioxide concentration combines the opening of the gas exchange valve and reflects the production and discharge rate of carbon dioxide.

[0056] According to the calculation equation of the carbon dioxide concentration change of this embodiment, the amount of carbon dioxide discharged from the fermentation unit 100 through the gas exchange valve per unit time is calculated as follows:

[0057] k out ·U(t)·f(t)·d(t)

[0058] 3. Real-time monitoring of oxygen concentration in the fermentation unit 1OO and carbon dioxide concentration And according to the preset oxygen concentration target value and the preset CO2 concentration target value Calculate the error and error The specific calculation process is as follows.

[0062]

[0063] According to the error calculation of this embodiment, a positive error indicates that the actual concentration is lower than the preset concentration; a negative error indicates that the actual concentration is higher than the target concentration.

[0064] 4. The control signal calculation of the opening and closing amplitude of the gas exchange valve is performed based on the error calculation result. The calculation formula of the control signal of the opening and closing amplitude u(t) of the gas exchange valve is as follows:

[0065]

[0066] According to the control signal calculation formula of the opening and closing amplitude of the gas exchange valve, It represents the accumulation of errors from the initial time t=0 to the current time t. The integral term reflects the sum of all errors in the past period of time. It is used to eliminate the steady-state error of the system. Since the historical error is taken into account, the control signal of this system is smoother and more stable. According to the control calculation formula of the opening and closing amplitude of the gas exchange valve, is the integral gain, which determines the degree of influence of the integral part on the control signal.

[0067] In the calculation formula of the opening and closing amplitude control signal of the gas exchange valve, K p , K i , K d They represent proportional gain, integral gain and differential gain respectively. These coefficients are used to adjust the response of the controller to the error, thereby achieving precise control of the system (such as the opening and closing amplitude of the gas exchange valve).

[0068] The larger the proportional gain, the faster the controller responds to the error. The proportional gain determines the intensity of the controller's direct response to the current error. p It is preferred to set the initial value based on experience and experimental data, and then gradually adjust it through trial and error. p It can also be calculated by the Ziegler-Nichols method (determine the initial value by the critical proportionality method or the critical period method). p (A parameter in the controller, which determines the direct response strength of the controller to the current error, the response speed and stability of the control system) until the system oscillates with equal amplitude, and record the proportional gain k at this time u (Critical proportionality, which is a key parameter determined by the Ziegler-Nichols method, is the proportional gain value that enables the system to produce equal-amplitude oscillations under step response, k u is the proportional gain where the system starts to become unstable and produces equal-amplitude oscillations) and the oscillation period T u The initial value is calculated as follows:

[0069] K p =0.6·K u

[0070] The larger the integral gain, the stronger the controller's ability to compensate for the accumulated error, which helps to eliminate the steady-state error. The integral gain determines the intensity of the controller's response to the past error accumulation. i It is preferred to set the initial value based on experience and experimental data, and then gradually adjust it through trial and error. i It can also be calculated by the Ziegler-Nichols method. i Until the system oscillates with equal amplitude, record the proportional gain k at this time u (The meaning is as mentioned above and will not be repeated here) and the oscillation period T uThe initial value is calculated as follows:

[0071]

[0072] The larger the differential gain, the better the controller's ability to predict error changes, which helps reduce overshoot and oscillation. The differential gain determines the strength of the controller's response to the future rate of error change. K d It is preferred to set the initial value based on experience and experimental data, and then gradually adjust it through trial and error. d It can also be calculated by the Ziegler-Nichols method. d Until the system oscillates with equal amplitude, record the proportional gain K at this time u and the oscillation period T u The initial value is calculated as follows:

[0073]

[0074] In this embodiment, according to the actual oxygen concentration and error measured To calculate the required opening and closing amplitude of the gas exchange valve, the opening and closing amplitude of the gas exchange valve The calculation formula is as follows:

[0075]

[0076] in, The meaning and method of obtaining are the same as above K p , K i , K d The corresponding content will not be repeated here.

[0077] In this embodiment, according to the actual measured carbon dioxide concentration and error To calculate the required opening and closing amplitude of the gas exchange valve, the opening and closing amplitude of the gas exchange valve The calculation formula is as follows:

[0078]

[0079] in The meaning and method of obtaining are the same as above K p , K i , K d The corresponding content will not be repeated here.

[0080] 5. The control signal is integrated to obtain the final control signal of the opening and closing amplitude of the gas exchange valve. The calculation formula of the final control signal of the opening and closing amplitude u(t) of the gas exchange valve is as follows:

[0081]

[0082] in and They are the oxygen weighting factor and the carbon dioxide weighting factor, which are used to balance the importance of oxygen and carbon dioxide control.

[0083] According to a preferred embodiment, and The determination is dynamically adjusted according to the different stages of fermentation.

[0084] Specifically, in the early stage of fermentation, the control of oxygen concentration is more important, while in the later stage of fermentation, the control of carbon dioxide concentration is more important.

[0085] The adjustment formula is as follows:

[0086] Initial fermentation period (0-12 hours)

[0087]

[0088] Mid-fermentation period (12-24 hours)

[0089]

[0090] Late fermentation (after 24 hours)

[0091]

[0092] The opening and closing amplitude of the gas exchange valve at different time stages is calculated according to the weight coefficient of the corresponding fermentation stage. The calculation formula is:

[0093]

[0094] According to a preferred embodiment, and It is dynamically adjusted according to the error size. For example, if the error of a parameter is large, it means that the control of this parameter is more important. The adjustment formula of the weight coefficient is as follows:

[0095]

[0096] The following are some examples:

[0097] Oxygen concentration error at the current time t The carbon dioxide concentration error at the current time t is 2 mg / L. -1mg / L, dynamically adjust the weight coefficient:

[0098]

[0099] Assumptions Substitute the opening and closing amplitude of the gas exchange valve The calculation formula of the final control signal is as follows:

[0100]

[0101] According to a preferred embodiment, and It is dynamically adjusted according to the fermentation rate. When the fermentation rate is high, more oxygen supply is needed; conversely, if the fermentation rate is low, more carbon dioxide needs to be discharged. The weight adjustment formula is as follows:

[0114] According to this embodiment, the mapping function is used to map the control signal u(t) of the opening amplitude of the gas exchange valve output by the controller to a reasonable opening and closing frequency range. The specific calculation formula of the mapping function in this embodiment is as follows:

[0132] The final calculation results of the opening and closing frequency are as follows:

[0133]

[0134] Through the above calculation steps, this embodiment maps the control signal output by the controller to a reasonable opening and closing frequency range, and further integrates the control requirements of oxygen and carbon dioxide to ensure that the opening amplitude and opening and closing frequency of the gas exchange valve meet the control objectives, thereby optimizing the fermentation conditions and improving the flavor and quality of the wine.

[0135] Specifically, oxygen is an important factor in the growth and reproduction of yeast. This embodiment can ensure that the yeast obtains sufficient oxygen in the early stage of fermentation by precisely controlling the supply of oxygen, promote its rapid reproduction, and improve fermentation efficiency. In the later stage of fermentation, too much oxygen will cause excessive oxidation of the wine and affect the flavor. This system can avoid this situation and maintain the freshness and taste of the wine by precisely controlling the oxygen concentration. The system provided in this embodiment balances the concentrations of oxygen and carbon dioxide by precisely controlling the opening amplitude and opening and closing frequency of the gas exchange valve. This setting can optimize the yeast metabolic pathway and promote the production of beneficial flavor substances, such as esters, acids and alcohol compounds, thereby enhancing the aroma and taste of the wine. Furthermore, the system of this embodiment can ensure the consistency and repeatability of each fermentation process, reduce differences between batches, and improve the stability of product quality.

[0136] To further enhance the sealing performance, the tank cover 110 can also be designed with a pressure monitoring and leakage warning mechanism. This mechanism uses a monitoring component to continuously monitor the pressure dynamics in the tank. Once an abnormal pressure is detected, indicating a possible leakage risk, the alarm program will be immediately activated, allowing operators to respond quickly and take corresponding measures to ensure the safety and stability of the fermentation process.

[0137] Preferably, if Figure 1 As shown, the connection between the tank cover 110 and the integrated tank body 300 adopts an automated or semi-automated fastening system. According to one embodiment, the tank cover 110 and the integrated tank body 300 can be connected by bolts. In this connection method, an electric or pneumatic wrench is used to accurately control the rotation speed and tightening torque of the bolts to ensure that each bolt can achieve the same tightening degree, thereby avoiding leakage problems caused by uneven tightening. According to another embodiment, the tank cover 110 and the integrated tank body 300 can be connected by a quick locking buckle. This connection method adopts a spring loading and locking mechanism, which can be quickly locked by a simple pressing operation. At the same time, the built-in safety lock ensures that there will be no accidental unlocking during the fermentation process.

[0138] Preferably, if Figure 1 As shown, the bottom of the integrated tank body 300 is provided with a structure directly connected to the yellow water tank 120, which is used to collect the yellow water byproduct produced during the fermentation process. In the fermentation unit 100, the mash loaded inside precipitates yellow water rich in dissolved substances under the metabolism of microorganisms. Due to the effect of gravity, these yellow waters converge to the bottom of the tank body. Several holes arranged at the bottom of the integrated tank body 300 are aligned with the collection holes of the yellow water tank 120 below to form a channel for the circulation of yellow water. When the yellow water tank 120 is installed below the integrated tank body 300, the yellow water can flow smoothly into the yellow water tank 120 through the holes to achieve effective collection. In order to improve the convenience of operation, the bottom or side wall of the yellow water tank 120 is also equipped with a special drain port 224, which is convenient for completely discharging the accumulated yellow water after the fermentation cycle is completed for subsequent treatment or reuse.

[0139] Preferably, if Figure 1 As shown, considering the need to achieve a stable and easily automated connection and separation between the integrated tank body 300 and the yellow water tank 120, a number of docking interfaces are evenly distributed on the bottom of the integrated tank body 300, and a mounting seat matching the bottom interface of the integrated tank body 300 is preset on the top of the yellow water tank 120. The mounting seat can guide and position the interface to ensure that the two can be quickly and accurately docked during the lifting process.

[0140] Preferably, if Figure 1As shown, in order to achieve a stable and easy-to-automate connection and separation between the integrated tank body 300 and the yellow water tank 120, several groups of docking interfaces are evenly distributed at the bottom of the tank body. These interfaces are designed in a circular or rectangular shape, and the interfaces have been pre-tested and simulated to ensure that they have sufficient contact area when docking with the yellow water tank 120 to enhance the stability and reliability of the connection. The outer edge of each group of docking interfaces is equipped with a dedicated mechanical or electric locking mechanism. The mechanical locking mechanism can achieve automatic tightening through a spring or inclined design, while the electric locking mechanism can automatically activate the lock using a motor and a sensor to ensure a stable connection of the interface. The material of the docking interface is made of high-strength aluminum alloy or stainless steel, which has good corrosion resistance and mechanical properties and can adapt to various chemical substances produced during fermentation and distillation. At the same time, the interface design takes sealing into consideration and is equipped with a rubber sealing pad to further prevent liquid leakage and ensure the safety of operation.

[0141] Preferably, a mounting seat matching the bottom interface of the integrated tank body 300 is preset at the top of the yellow water tank 120. The mounting seat is in the shape of a groove and is designed as a guiding structure that can accurately guide the docking interface. The inner wall of the mounting seat adopts a certain slope, such as 15 to 30 degrees. Such a design helps to naturally guide the docking interface into a fixed position through gravity and the inclination angle during the docking process. In addition, the bottom of the mounting seat is equipped with anti-slip material to enhance stability during the docking process and reduce potential displacement risks. The mounting seat is located at the edge area of ​​the top of the yellow water tank 120 to ensure better docking accuracy during hoisting and docking.

[0142] Preferably, after the mash in the integrated tank body 300 completes fermentation in the area where the fermentation unit 100 is located, it can be transported to the distillation unit 200 along with the integrated tank body 300 by the intelligent transport robot. Figure 2 As shown, the distillation unit 200 is the part of the integrated system responsible for completing the mash distillation process, and includes two parts: a base 21O and a retort cover 230. The base 21O is the basic structure of the distillation unit 200, and its design purpose is to provide a stable support platform for the integrated tank body 300. The base 210 can be designed in a rectangular or square shape, and has a size and shape that matches the bottom of the integrated tank body 300 to ensure that the integrated tank body 300 can be placed stably thereon. The base 210 enhances its load-bearing capacity and stability by forming a frame structure and having built-in reinforcing ribs. The base 21O is fixed in position and is usually installed on the ground of the distillation workshop, and is in direct contact with the integrated tank body 300 through the support surface at the bottom.

[0143] Preferably, if Figure 2As shown, the retort cover 230 is another component of the distillation unit 200, which is designed to be openable and closable so as to provide a necessary closed environment during the distillation process. The retort cover 230 is designed to be circular or in a shape that matches the top opening of the integrated tank body 300, and the edge of its structure includes a sealing gasket and a fastening device, such as a bolt or a buckle, to ensure a good seal with the integrated tank body 300 during the distillation process. The retort cover 230 is located at the top of the integrated tank body 300 and is fixed by a connection mechanism with the top of the tank body to prevent steam leakage during the distillation process.

[0144] Preferably, if Figure 2 As shown, the base 210 of the distillation unit 200 is designed to consist of two structural frames, namely the first frame 211 and the second frame 212. The two frames are consistent in height to ensure the stability of the entire base 210 and the balance of the structure. The first frame 211 is a part of the base 210, and its top is open, providing space for the placement of the integrated tank body 300. The top of the first frame 211 is directly connected to the bottom pot 220, which is a device used for heating during the distillation process. The opening on its top is kept flush with the top of the first frame 211, and the liquid required for distillation can be filled inside. This design allows the bottom pot 220 to directly heat the mash in the integrated tank body 300 to promote the distillation process. The second frame 212 is connected to the first frame 211, and its top is equipped with a flip assembly 240, which is used to control the opening and closing operation of the retort cover 230. The retort cover 230 is a component used to cover the top of the integrated tank body 300 during the distillation process to form a closed environment. The design of the flip assembly 240 allows the retort cover 230 to be opened when necessary to facilitate loading or unloading, and closed during the distillation process to prevent steam from leaking out.

[0145] Preferably, if Figure 2As shown, the bottom pot 220 is designed in the distillation unit 200 to provide the heat energy required for the distillation of mash. The shape of the bottom pot 220 can be round or square to adapt to the specific shape of the bottom of the integrated tank body 300. The bottom pot 220 can be fixed to the top of the first frame 211 by bolting or other detachable means, ensuring direct contact with the bottom of the integrated tank body 300, thereby achieving stable and effective transfer of heat energy. A water inlet pipe 223 is arranged on the side wall of the bottom pot 220, and the pipeline is connected to the external clean water supply system. The design of the water inlet pipe 223 allows clean water to be injected into the bottom pot 220 for heating during the distillation process. The bottom pot 220 is also provided with a steam coil 221, which is an internal channel that allows steam to pass through and heat the clean water in the bottom pot 220. The steam coil 221 is arranged in a manner that it is as full as possible within the horizontal plane of the bottom pot 220 to ensure that it has a large heat transfer area. This design enables the bottom pot 220 to be heated quickly and evenly, providing the necessary heat energy for the distillation of the mash. The bottom of the bottom pot 220 is also provided with a drain port 224, which is used to drain the liquid in the bottom pot 220 after the distillation process is completed. The design of the drain port 224 allows the bottom pot 220 to return to its initial state after each use, so as to facilitate the next distillation operation. The configuration of the water inlet pipe 223, the steam coil 221 and the drain port 224 are all closely connected with the structure of the bottom pot 220 to avoid leakage of clean water or steam during the distillation process, thereby ensuring the continuity and efficiency of the distillation process.

[0146] Preferably, if Figure 2As shown, the liquid level meter 222 is an important monitoring device in the distillation process, and its position can be set on the side wall of the bottom pot 220 to intuitively display the liquid level of the clean water. The structural design of the liquid level meter 222 allows it to directly contact the water level inside the bottom pot 220, and measure the water level through a float, a pressure sensor or other sensing technology. The position of the liquid level meter 222 is fixed on the column of the first frame 211. This design enables the brewing staff to easily observe and read the water level information. The liquid level meter 222 and the valve of the water inlet pipe 223 are linked through an automated control program. When the liquid level meter 222 detects that the clean water level inside the bottom pot 220 is lower than the preset minimum limit, the valve will automatically open to allow clean water to flow into the bottom pot 220 to replenish the water level. On the contrary, when the liquid level meter 222 detects that the water level exceeds the preset maximum limit, the valve will automatically close to prevent water from overflowing. This automated control reduces the need for manual intervention and ensures that the distillation environment in the bottom pot 220 remains stable during the distillation process. The automatic control program of the liquid level meter 222 and the valve is also equipped with components such as sensors, controllers and actuators. The sensor is responsible for monitoring the water level, the controller receives the signal from the sensor and makes logical judgments, and the actuator performs the action of opening or closing the valve according to the instructions of the controller. The automatic control design of the liquid level meter 222 of the bottom pot 220 and the valve of the water inlet pipe 223 ensures that the water level in the bottom pot 220 is maintained within an appropriate range during the distillation process, thereby optimizing the distillation effect and reducing the complexity of manual operation.

[0147] Preferably, if Figure 3 As shown, the top of the steamer cover 230 is designed with an air outlet 231. The main function of the air outlet 231 is to guide the wine vapor generated by the mash during the distillation process, and collect and condense it through the flip assembly 240 assembled on the top of the second frame 212. The shape and position design of the air outlet 231 need to ensure the effective collection of the wine vapor. The air outlet 231 is preferably configured at the center of the steamer cover 230, and its structure is designed to extend upward to guide the wine vapor to the flip assembly 240. The shape of the air outlet 231 can be configured as a circle or a square to adapt to the top shape of the steamer cover 230 with an umbrella-like structure. This design helps to collect and gather the wine vapor so that it can be guided by the flip assembly 240. The flip assembly 240 configured on the top of the second frame 212 allows the steamer cover 230 to be opened when necessary to facilitate loading or unloading. During the distillation process, the flip assembly 240 controls the steamer cover 230 to be closed to keep the wine vapor from leaking. In addition, a water measuring pipe 232 is also arranged near the air outlet 231 on the top of the steamer cover 230. The water measuring pipe 232 is used to measure the water after the mash in the integrated tank body 300 is distilled, so as to increase the water content of the mash, so as to facilitate the normal progress of the subsequent brewing process. The water measuring pipe 232 is bent above the steamer cover 230, so that its outlet can penetrate into the steamer cover 230 in a manner perpendicular to the plane where the steamer cover 230 is located.

[0148] Preferably, if Figure 3 As shown, the flip assembly 240 includes an assembly platform 241 disposed on the top of the second frame 212. The assembly platform 241 is designed as a box-like structure and has a certain height so that the support plate 242 of the flip assembly 240 can be arranged on its top surface. The top support plate 242 of the assembly platform 241 is designed as two parallel plates, and each support plate 242 adopts a reinforcing rib or rib structure to enhance its overall rigidity and bending resistance. The connection between the support plate 242 and the assembly platform 241 of the flip assembly 240 is welded, bolted or other mechanically connected to ensure a firm and reliable connection. Each support plate 242 is provided with a gas through hole 247 that passes through itself, and these gas through holes 247 can serve as the final outlet of the wine vapor in the distillation unit 200. Its diameter is designed to match the interface of the condensation equipment so as to realize the liquefaction collection of the wine vapor. Further preferably, the support plate 242 also serves as a support component for the delivery pipe 244, which is the intermediate passage for the wine vapor from the steamer cover 230 to the condensation device. The end of the delivery pipe 244 is connected to the air-passing hole 247 on the support plate 242, and the starting end is provided with a bell mouth 245. The design of the bell mouth 245 includes a wide mouth, the size of which matches the air outlet 231 at the top center of the steamer cover 230. The gradually closing structure of the bell mouth 245 helps to collect the wine vapor generated from the integrated tank body 300 and transport it to the condensation device through the delivery pipe 244, so as to realize the collection and condensation of the wine vapor. The design and configuration of the assembly platform 241, the support plate 242, the air-passing hole 247, the delivery pipe 244 and the bell mouth 245 of the flip assembly 240 together constitute an efficient wine vapor collection circuit, ensuring that the wine vapor can be effectively guided and collected from the entire process from generation to condensation, thereby improving the efficiency of the distillation process and the product quality.

[0149] Preferably, if Figure 3As shown, the flip assembly 240 of the distillation unit 200 includes a connector 243, which is connected to the support plate 242 on the top of the assembly platform 241 by a movable connection. The design of the connector 243 ensures that it has sufficient rigidity and bending resistance. It can adopt a plate-like structure and be configured as two oppositely arranged components to be arranged on the inner side of the support plate 242. This layout allows the connector 243 to provide a stable support for the delivery pipe 244. The shape of the connector 243 is designed to be a narrow and long triangle, in which the two sides are longer and the bottom side is shorter. This design enables the connector 243 to clamp the delivery pipe 244 between the two connectors 243, thereby protecting the delivery pipe 244. The long side of the connector 243 is consistent with the extension direction of the delivery pipe 244, ensuring the stability of the delivery pipe 244 during the operation of the flip assembly 240. A bend is provided at the end of the delivery pipe 244 to change the direction of travel of the delivery pipe 244 so that it can be connected to the air passage hole 247 provided in the support plate 242. In order to adapt to the extension path of the delivery pipe 244, a corner of the bottom edge of the connecting member 243 is stretched in the extension direction of the bend, so that the connecting member 243 forms a structure approximately concave quadrilateral. This structure enhances the protection of the delivery pipe 244 and ensures the safety and stability of the delivery pipe 244 during the operation of the flip assembly 240. The movable connection design between the connecting member 243 and the support plate 242 allows relative movement between the two, that is, the connecting member 243 can drive the delivery pipe 244 to perform synchronous flipping movement under the drive of the flip assembly 240, so that the steamer cover 230 connected to the starting end of the delivery pipe 244 through the bell mouth 245 can be opened or closed at the top opening of the integrated tank body 300. The design of the connector 243 not only provides physical protection for the delivery pipe 244 , but also takes into account the dynamic stability during operation, thereby ensuring efficient and safe operation of the entire distillation unit 200 .

[0150] Preferably, if Figure 3As shown, the connector 243 is approximately in a concave quadrilateral structure, and its three acute-angle vertices are provided with connectors that keep the two connectors 243 connected. First, the first connector is arranged at the bell mouth 245 closest to the starting end of the delivery pipe 244. Its design is intended to ensure that the main body of the delivery pipe 244 or most of its area is included in the protection area of ​​the connector 243 to ensure the safety and stability of the structure. Secondly, the second connector is deployed at the end of the delivery pipe 244, and adopts a ball bearing-like mechanism to form a flexible and stable rotation interface with the preset air hole 247 on the support plate 242. This design allows the connector 243 to rotate freely with the air hole 247 as the central axis, thereby realizing the opening and closing operation of the steamer cover 230, which not only ensures smooth rotation movement, but also takes into account the sealing performance required for the transportation of wine vapor. Furthermore, the third connector is located at the inner angle formed by the intersection of the long side and the short side of the connector 243, and is integrated with a hydraulic rod 249 as a power source through a rotating connection. This configuration makes the third connecting member the power output point for driving the steamer cover 230 to flip, ensuring the precise execution and high-efficiency conversion of the flipping action. In order to further strengthen the connection strength and stability between the connecting member 243 and the steamer cover 230, not only is the second connecting member firmly fixed by welding, flange fastening or high-strength bolt connection and other engineering means, but the long side of the connecting member 243 close to the steamer cover 230 is also specially provided with a support rod 246 structure, which extends vertically toward the steamer cover 230 to form an additional rigid support. This design significantly enhances the overall connectivity between the steamer cover 230 and the connecting member 243, and can effectively prevent the steamer cover 230 from shifting relative to the top opening of the integrated tank body 300 even under the action of external forces, thereby ensuring the reliability and safety of the equipment operation.

[0151] Preferably, if Figure 2 , Figure 3As shown, the flip assembly 240 uses a hydraulic transmission mechanism to accurately and stably drive the steamer cover 230 to perform a flipping action. Specifically, a bypass support 250 is arranged on the side of the assembly platform 241 away from the first frame 211. The bypass support 250 serves as a stable support point for the hydraulic transmission mechanism of the flip assembly 240, and a hydraulic cylinder 248 that generates and transmits hydraulic power is movably connected to it. The interface of the hydraulic cylinder 248 is connected to the hydraulic rod 249 on the connecting member 243, and the hydraulic rod 249 forms a movably connected with the connecting member 243 to realize the conversion of hydraulic energy into mechanical energy. During the hydraulic transmission process, when the hydraulic cylinder 248 applies a compressive force, the hydraulic rod 249 shortens accordingly, and uses this as a power to drive the connecting member 243 to rotate around the preset air through hole 247 on the support plate 242. This movement directly causes the steamer cover 230, which is tightly connected to the bell mouth 245 at the starting end of the delivery pipe 244, to perform an opening action away from the top opening of the integrated tank body 300. At the same time, in order to maintain the smoothness and stability of the hydraulic transmission, the hydraulic cylinder 248 flexibly rotates around the bypass support 250 according to the change in the extension direction of the hydraulic rod 249 in the vertical plane, and deflects toward the first frame 211 to adapt to the adjustment of the transmission path. On the contrary, when the hydraulic cylinder 248 releases pressure and applies tensile force, the hydraulic rod 249 extends accordingly, pushing the connecting member 243 to rotate in the opposite direction around the air through hole 247, driving the steamer cover 230 to move closer to the top opening of the integrated tank body 300, and completing the covering operation. In this process, the hydraulic cylinder 248 again rotates in the opposite direction according to the movement trajectory of the hydraulic rod 249, with the assistance of the bypass support 250, away from the position of the first frame 211, ensuring that the entire hydraulic transmission mechanism maintains a high degree of stability and efficiency.

The tipping mechanism in this area can pour the mash from the integrated tank body 300 into the mixing equipment, and fully mix it with the rice husks that are also added to the mixing equipment. The evenly mixed mash is loaded into the integrated tank body 300 according to a certain volume, and then transported to the area where the distillation unit 200 is located by the intelligent transfer robot to complete the subsequent distillation process.
