Description

Technical Field

[0001] The present application relates to the technical field of fermentation equipment, and in particular to a fermentation device for food production. Background Art

[0002] Fermentation refers to the process by which microorganisms, under aerobic or anaerobic conditions, are used to produce microbial cells themselves, or their direct or secondary metabolites. Fermentation is widely used in food, herbal beverages, winemaking, pharmaceutical manufacturing, and waste treatment.

[0003] An increasing number of fermentation products now involve multi-species collaborative or staged fermentation. In these processes, different strains have significantly different requirements for temperature, nutrients, and environmental conditions. For example, the staged metabolic regulation of yeast and acetic acid bacteria in liquor brewing, the collaborative fermentation of thermophilic Streptococcus and Lactobacillus in probiotic products, and the sequential action of hydrolytic and alcohol-producing bacteria in biofuel production all require the introduction of specific strains at different stages of fermentation and the precise control of their activity.

[0004] These complex fermentation processes require fermentation equipment to flexibly adjust fermentation conditions to meet the requirements of the product's different fermentation stages. However, existing fermentation equipment often uses a single fermentation tank setup, within which the fermentation conditions are limited, making it difficult to flexibly adjust the fermentation environment according to changes in the fermentation stage. This significantly limits the diversity and quality of fermented products. In particular, when fermenting different products, due to the different fermentation stages, existing fermentation equipment is difficult to flexibly adjust, making it difficult to adapt to different fermentation products. Summary of the Invention

[0005] The present application provides a fermentation device for food production, the purpose of which is to enable the fermentation device to be flexibly adjusted to adapt to the fermentation requirements of different fermentation products, so that the fermentation device can adapt to different fermentation products, thereby improving the applicability of the fermentation device.

[0006] The present application provides a food production fermentation device that adopts the following technical solution: A fermentation device for food production comprises a pretreatment tower, a vertical fermentation tower and a post-treatment chamber, wherein the pretreatment tower, the vertical fermentation tower and the post-treatment chamber are connected in sequence; the vertical fermentation tower comprises a plurality of fermentation chambers, which are stacked vertically and connected in sequence along the vertical direction, and two adjacent fermentation chambers are detachably connected; the fermentation chamber on the bottom layer is connected to the pretreatment tower, and the fermentation chamber on the top layer is connected to the post-treatment chamber; the fermentation chamber is provided with a material feeding control mechanism, a supplement injection mechanism, a temperature control mechanism and an aeration mechanism, the material feeding control mechanism is used to control the feeding and discharging of the fermentation chamber, the supplement injection mechanism is used to inject bacterial liquid into the fermentation chamber, the temperature control mechanism is used to control the temperature in the corresponding fermentation chamber, and the aeration mechanism is used to supply high-pressure gas into the fermentation chamber.

[0007] By adopting the above technical solution, first, the pretreatment tower, vertical fermentation tower and post-treatment chamber are connected in sequence, so that after the raw materials enter the fermentation device, the raw materials undergo pretreatment, fermentation and post-treatment links in sequence, which can realize the whole process of raw material fermentation and thus meet the basic functions of the fermentation device.

[0008] On this basis, the vertical fermentation tower includes several fermentation chambers, which are stacked in the vertical direction and connected in sequence. Two adjacent fermentation chambers can be detachably connected, which makes it easy to freely increase or decrease the number of fermentation chambers.

[0009] The fermentation chamber is equipped with a material feeding control mechanism, a supplement injection mechanism, a temperature control mechanism and an aeration mechanism. Among them, the material feeding control mechanism can control the feeding and discharging of the fermentation chamber to ensure the orderly flow of raw materials; the supplement injection mechanism can inject bacterial liquid into the fermentation chamber to provide the necessary bacterial species for fermentation; the temperature control mechanism can control the temperature in the fermentation chamber to keep the raw materials in an environment suitable for fermentation; the aeration mechanism can supply high-pressure gas into the fermentation chamber, which can not only increase the dissolved oxygen in the raw materials, but also stir the raw materials, and also increase the pressure in the fermentation chamber to achieve raw material transportation.

[0010] Based on the design of the fermentation chamber, each fermentation chamber can independently meet the requirements of a fermentation stage of the fermentation product, so that the applicability of the vertical fermentation tower can be improved by increasing or decreasing the number of fermentation chambers.

[0011] Therefore, the structural setting of the vertical fermentation tower makes it easy to adapt to the fermentation requirements of different fermentation products by increasing the number of fermentation chambers, so that the fermentation device can adapt to different fermentation products, thereby improving the applicability of the fermentation device.

[0012] Optionally, the aeration mechanism includes an air inlet pipe, one end of the air inlet pipe is connected to the air supply mechanism, and the other end is connected to the outer wall of the fermentation chamber. Several aeration pipes are provided in the fermentation chamber, and the several aeration pipes are all connected to the air inlet pipe.

[0013] By adopting this technical solution, the air supply mechanism can input high-pressure gas into the air inlet pipe. This high-pressure gas is discharged into the raw materials in the fermentation chamber through the aeration pipe, forming tiny bubbles. This can increase the dissolved oxygen content of the raw materials and also agitate the raw materials. Furthermore, as the air supply mechanism increases the air volume, the pressure in the fermentation chamber increases, which can press the raw materials in the fermentation chamber into another adjacent fermentation chamber, thus realizing the raw material transportation function.

[0014] Optionally, the gas supply mechanism includes an air source electromagnetic reversing valve, an oxygen source and an inert gas source, and the oxygen source, the inert gas source and the air intake pipe are all connected to the air source electromagnetic reversing valve, and the air source electromagnetic reversing valve is used to switch the air intake pipe to be connected with the oxygen source or the inert gas source.

[0015] By adopting the above technical solution, the air source electromagnetic reversing valve in the air supply mechanism can control the connection between the air intake pipe and the oxygen source or the inert gas source. When the air intake pipe is connected to the oxygen source, it can be used to increase the dissolved oxygen of the raw material. When the air intake pipe is connected to the inert gas source, the inert gas can only realize the raw material stirring function. This enables the aeration mechanism to be freely switched to adapt to different fermentation requirements.

[0016] Optionally, the fermentation chamber is connected to a pressure relief mechanism.

[0017] By adopting the above technical solution, the fermentation chamber is connected to the pressure relief mechanism to prevent the internal pressure of the fermentation chamber from being too high, thereby ensuring that the fermentation process is carried out safely and stably.

[0018] Optionally, the pressure relief mechanism includes a pressure relief pipe, a first pressure relief branch pipe, a second pressure relief branch pipe and a pressure relief electromagnetic reversing valve. The pressure relief pipe is connected to the fermentation chamber, and the pressure relief pipe, the first pressure relief branch pipe and the second pressure relief branch pipe are all connected to the pressure relief electromagnetic reversing valve. The pressure relief electromagnetic reversing valve is used to switch the pressure relief pipe to be connected to the first pressure relief branch pipe or the second pressure relief branch pipe; an automatic pressure relief valve is provided on the first pressure relief branch pipe, and a pressure relief control valve is provided on the second pressure relief branch pipe.

[0019] By adopting the above technical solution, the pressure relief mechanism can control the connection between the pressure relief pipe and the first pressure relief branch pipe or the second pressure relief branch pipe through the pressure relief solenoid reversing valve. This allows for switching between two different pressure relief modes: First, when the aeration mechanism is aerating the raw materials to achieve agitation or increase dissolved oxygen in the raw materials, the first pressure relief branch pipe is connected to the pressure relief pipe, and the automatic pressure relief valve automatically performs the pressure relief function to ensure stable pressure in the fermentation chamber. Second, when the aeration mechanism is used to transport raw materials, the second pressure relief branch pipe is connected to the pressure relief pipe, continuously increasing the gas and internal pressure in the fermentation chamber to achieve the raw material transportation function. After the raw material transportation is completed, the pressure relief valve is actively opened to achieve the pressure relief function.

[0020] Optionally, the supplement injection mechanism includes a three-way pipe, a syringe assembly and a boost injection assembly, and the three ends of the three-way pipe are provided with supplement control valves, and the supplement control valve is used to control the opening and closing of the corresponding end of the three-way pipe; one end of the three-way pipe is connected to the fermentation chamber, the other end is connected to the syringe assembly, and another end is connected to the boost injection assembly; the syringe assembly is used to inject bacterial liquid into the three-way pipe, and the boost injection assembly is used to pass high-pressure gas into the three-way pipe.

[0021] By adopting the above technical solution, the supplement injection mechanism, through the coordinated design of the tee, syringe assembly, and boost injection assembly, allows the syringe assembly to inject bacterial liquid into the tee, while the boost injection assembly can inject high-pressure gas into the tee, allowing the high-pressure gas to blow the bacterial liquid in the tee directly into the fermentation chamber. Since the bacterial liquid is injected by high-pressure gas, this ensures that the bacterial liquid is dispersed as much as possible in the raw materials.

[0022] Optionally, the pretreatment tower includes an ultrasonic treatment chamber, a cold plasma treatment chamber and an enzymatic hydrolysis chamber, and the ultrasonic treatment chamber, cold plasma treatment chamber and enzymatic hydrolysis chamber are connected in sequence, and the enzymatic hydrolysis chamber is connected to the fermentation chamber at the bottom; and the ultrasonic treatment chamber, cold plasma treatment chamber and enzymatic hydrolysis chamber are all provided with a material feeding control mechanism, a supplement injection mechanism, a temperature control mechanism and an aeration mechanism.

[0023] By adopting the above technical solution, the structural design of the pretreatment tower allows the raw materials to pass through the ultrasonic treatment chamber, cold plasma treatment chamber and enzymatic hydrolysis chamber in sequence, which makes the raw materials meet the fermentation requirements after ultrasonic treatment, cold plasma treatment and enzymatic hydrolysis treatment. The material feeding control mechanism installed in each chamber can control the in and out of materials to ensure the orderly progress of each treatment link; the supplement injection mechanism can add supplements as needed, such as adding enzyme solution to the enzymatic hydrolysis chamber to enzymatically hydrolyze the raw material polysaccharides and reduce viscosity to facilitate transportation; the temperature control mechanism can adjust the temperature in the chamber to keep the raw materials in a suitable environment and improve the treatment effect; the aeration mechanism can introduce high-pressure gas, which can increase the dissolved oxygen in the raw materials, stir the raw materials, and use high pressure to achieve raw material transportation, thereby improving the efficiency and quality of pretreatment and laying a good foundation for the subsequent fermentation stage.

[0024] Optionally, the vertical fermentation tower is further provided with a mounting seat, and a plurality of the fermentation chambers are stacked on the mounting seat, and the mounting seat is detachably connected to adjacent fermentation chambers.

[0025] By adopting the above technical solution, the mounting base provided on the vertical fermentation tower can accommodate several fermentation chambers stacked thereon, and the mounting base is detachably connected to adjacent fermentation chambers. This structural design facilitates the installation and disassembly of the fermentation chambers.

[0026] Optionally, the vertical fermentation tower also includes a stirring assembly, the stirring assembly includes a stirring motor and several stirring shafts, the stirring motor is located in the mounting seat, the stirring shafts are arranged in a one-to-one correspondence with the fermentation chambers, the stirring shafts are vertically arranged in the corresponding fermentation chambers, the stirring shafts are rotatably connected to the fermentation chambers, and both ends of the stirring shafts extend outside the fermentation chambers; the driving shaft of the stirring motor is coaxially and detachably connected to the adjacent stirring shafts, and the two adjacent stirring shafts are coaxially and detachably connected.

[0027] By adopting the above technical solution, the stirring motor is installed in the mounting base, and the stirring motor drive shaft is coaxially and detachably connected to the adjacent stirring shaft. The two adjacent stirring shafts are also coaxially and detachably connected. The stirring shafts correspond to each fermentation chamber and are vertically arranged in the fermentation chamber and rotatably connected to the fermentation chamber. This structure enables the stirring motor to drive multiple stirring shafts to rotate synchronously during operation, achieving active stirring of the raw materials in the fermentation chamber and enhancing the stirring effect of the raw materials. At the same time, the coaxial and detachable connection between the stirring shafts and the stirring motor drive shaft and the adjacent stirring shafts facilitates the addition and subtraction of the number of fermentation chambers as needed to meet the fermentation requirements of different raw materials.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. The present application adopts a vertical fermentation tower structure to facilitate increasing the number of fermentation chambers to adapt to the fermentation requirements of different fermentation products, so that the fermentation device can adapt to different fermentation products, thereby improving the applicability of the fermentation device.

[0029] 2. This application realizes the three functions of aeration, stirring and raw material transportation at the same time through the setting of the aeration mechanism. This design not only simplifies the structure of the fermentation chamber, but also can flexibly adjust the gas supply method and pressure control strategy according to different fermentation needs, thereby improving the efficiency and quality of the fermentation process.

[0030] 3. This application uses the aeration mechanism to allow raw materials to flow upward in a vertical fermentation tower. Because the aeration mechanism uses gas pressure to transport raw materials, this reduces energy consumption, equipment complexity, and maintenance costs. At the same time, the gas delivery method is gentler, effectively protecting the integrity of the strains and raw materials and avoiding mechanical damage. Furthermore, the aeration mechanism can also stir and mix the raw materials during transportation, preventing stratification and unevenness of the raw materials and improving fermentation efficiency and quality.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1 -Attached Figure 12 , further details of this application are given.

[0045] Example 1: A fermentation device for food production, referring to Figure 1 , including a pretreatment tower 1, a vertical fermentation tower 2, and a post-treatment chamber 3. The pretreatment tower 1, the vertical fermentation tower 2 and the post-treatment chamber 3 are connected in sequence.

[0046] Reference Figure 1 and Figure 2 The pretreatment tower 1 includes a cabin base 11, an ultrasonic treatment cabin 12, a cold plasma treatment cabin 13 and an enzymatic hydrolysis cabin 14. The ultrasonic treatment cabin 12, the cold plasma treatment cabin 13 and the enzymatic hydrolysis cabin 14 are stacked on the cabin base 11 from top to bottom, and the ultrasonic treatment cabin 12, the cold plasma treatment cabin 13 and the enzymatic hydrolysis cabin 14 are connected in sequence.

[0047] Reference Figure 1 and Figure 3 The vertical fermentation tower 2 includes a mounting base 21 and a plurality of fermentation chambers 22. The plurality of fermentation chambers 22 are stacked on the mounting base 21 in sequence along the vertical direction, and the plurality of fermentation chambers 22 are connected in sequence.

[0048] Reference Figure 1 The bottom fermentation chamber 22 is connected to the enzymatic hydrolysis chamber 14 , and the top fermentation chamber 22 is connected to the post-processing chamber 3 .

[0049] During food fermentation, the raw materials sequentially pass through the pretreatment tower 1, the vertical fermentation tower 2, and the post-processing chamber 3, with the final product discharged from the post-processing chamber 3. While passing through the pretreatment tower 1, the raw materials sequentially pass through the ultrasonic treatment chamber 12, the cold plasma treatment chamber 13, and the enzymatic hydrolysis chamber 14. During this process, the raw materials undergo ultrasonic treatment, cold plasma treatment, and enzymatic hydrolysis treatment, which ensures that the raw materials meet the fermentation requirements. While passing through the vertical fermentation tower 2, the raw materials sequentially pass through several fermentation chambers 22, which achieve multi-stage fermentation of the raw materials, thereby fermenting them into the final product.

[0050] In this embodiment, refer to Figure 1 The chamber base 11, ultrasonic treatment chamber 12, cold plasma treatment chamber 13 and enzymatic hydrolysis chamber 14 are detachably connected in sequence, specifically, by a plurality of bolts. The mounting base 21 and the plurality of fermentation chambers 22 are detachably connected in sequence, specifically, by a plurality of bolts.

[0051] Since several fermentation chambers 22 can be detachably connected in sequence, it is convenient to increase or decrease the number of fermentation chambers 22. Each fermentation chamber 22 corresponds to a fermentation stage, so the number of fermentation stages can be increased by increasing or decreasing the number of fermentation chambers 22, which can improve the applicability of the vertical fermentation tower 2 of this application.

[0052] Reference Figure 1 and Figure 4 The ultrasonic treatment chamber 12, cold plasma treatment chamber 13, enzymatic hydrolysis chamber 14, post-treatment chamber 3, and several fermentation chambers 22 are each equipped with a feed control mechanism 4, a temperature control mechanism 5, an aeration mechanism 6, a pressure relief mechanism 7, a sensor feedback mechanism 8, and a supplement injection mechanism 9. The fermentation device also includes an air supply mechanism 10 and a controller. The several aeration mechanisms 6 are all connected to the air supply mechanism 10. The feed control mechanism 4, temperature control mechanism 5, aeration mechanism 6, pressure relief mechanism 7, sensor feedback mechanism 8, and supplement injection mechanism 9 are all connected to the controller.

[0053] In this embodiment, the ultrasonic treatment chamber 12, cold plasma treatment chamber 13, enzymatic hydrolysis chamber 14, post-treatment chamber 3, and multiple fermentation chambers 22 have similar structures. Furthermore, the feed control mechanism 4, temperature control mechanism 5, aeration mechanism 6, pressure relief mechanism 7, sensor feedback mechanism 8, and supplement injection mechanism 9 in the cold plasma treatment chamber 13, enzymatic hydrolysis chamber 14, post-treatment chamber 3, and multiple fermentation chambers 22 have the same structure. Therefore, this embodiment uses the feed control mechanism 4, temperature control mechanism 5, aeration mechanism 6, pressure relief mechanism 7, sensor feedback mechanism 8, and supplement injection mechanism 9 in the ultrasonic treatment chamber 12 as an example for description.

[0054] Reference Figure 2 and Figure 4 The upper end of the ultrasonic treatment chamber 12 is connected to a primary feed pipe 121, and the lower end is connected to a first-level discharge pipe 122. The primary feed pipe 121 and the first-level discharge pipe 122 are both vertically arranged.

[0055] Reference Figure 4 and Figure 5 An ultrasonic assembly 123 is provided in the ultrasonic treatment chamber 12. The ultrasonic assembly 123 includes a plurality of ultrasonic vibration plates mounted on the inner sidewall of the ultrasonic treatment chamber 12. The plurality of ultrasonic vibration plates are spaced apart along the circumference of the ultrasonic treatment chamber 12, with the emitting surfaces of the ultrasonic vibration plates facing the central axis of the ultrasonic treatment chamber 12.

[0056] When the ultrasonic treatment chamber 12 is operating, raw materials are fed into the chamber through the primary feed pipe 121. The ultrasonic assembly 123 then activates, emitting ultrasonic waves. These high-frequency vibrations, at a frequency of 20 to 40 kHz, disrupt the raw material cells, promoting uniform mixing of the raw materials. The ultrasonic assembly 123, through the action of several ultrasonic oscillators, generates ultrasonic waves of uniform intensity throughout the chamber 12, ensuring uniform mixing of the raw materials.

[0057] Reference Figure 4 and Figure 5 The material feeding control mechanism 4 includes two material feeding control valves 41, which are respectively provided on the primary feeding pipe 121 and the primary discharging pipe 122. Under the control of the controller, the opening and closing of the two material feeding control valves 41 can be controlled, thereby controlling the feeding and discharging of materials into and out of the ultrasonic treatment chamber 12.

[0058] Reference Figure 4 and Figure 5The sensor feedback mechanism 8 includes several sensors, including at least a temperature sensor, a liquid level sensor, a pressure sensor, and a dissolved oxygen sensor. These sensors are all electrically connected to the controller and mounted on the ultrasonic treatment chamber 12. These sensors enable real-time monitoring of the ultrasonic treatment chamber 12, detecting the internal pressure, temperature, raw material liquid level, and dissolved oxygen in the chamber. Furthermore, based on the collected data, the controller facilitates the opening and closing of the feed control mechanism 4, the temperature control mechanism 5, the aeration mechanism 6, the pressure relief mechanism 7, and the supplement injection mechanism 9, ensuring precise control of the process.

[0059] Reference Figure 4 and Figure 5 The temperature control mechanism 5 is disposed outside the ultrasonic treatment chamber 12. In this embodiment, the temperature control mechanism 5 includes a jacket 51, which is disposed outside the ultrasonic treatment chamber 12, forming an interlayer space 52 between the jacket 51 and the ultrasonic treatment chamber 12. The jacket 51 is provided with a liquid inlet pipe 53 and a liquid outlet pipe 54, both of which are in communication with the interlayer space 52. The temperature control mechanism 5 also includes a liquid supply assembly, both of which are in communication with the liquid inlet pipe 53 and the liquid outlet pipe 54. The liquid supply assembly is electrically connected to the controller, and the liquid supply assembly can adopt a circulating pump system or a heat exchanger system.

[0060] Based on the coordinated arrangement of the liquid supply assembly and the jacket 51, the temperature control medium can circulate between the liquid supply assembly and the interlayer space 52, thereby realizing the recycling of the temperature control medium. The temperature control medium can be a cooling medium, a heating medium, or a heat-insulating medium. Therefore, there is heat exchange between the temperature control mechanism 5 and the ultrasonic treatment chamber 12, which can insulate, heat, or cool the raw materials in the ultrasonic treatment chamber 12. Therefore, based on the coordination of the temperature control mechanism 5 and the sensor feedback structure, the controller can regulate the temperature in the ultrasonic treatment chamber 12, thereby placing the raw materials in an optimal temperature environment, thereby improving the treatment effect of the ultrasonic treatment chamber 12 on the raw materials.

[0061] In addition, an electric heating element may be provided in the interlayer space 52 so as to achieve heating, cooling or heat preservation of the ultrasonic treatment chamber 12 by means of electric control.

[0062] Reference Figure 5 and Figure 6 Two sets of aeration mechanisms 6 are provided in the ultrasonic treatment chamber 12, spaced apart in the vertical direction. The aeration mechanisms 6 include an air inlet pipe 61 and a plurality of aeration pipes 62. The air inlet pipe 61 is provided on the outer wall of the ultrasonic treatment chamber 12, and the aeration pipes 62 are located within the ultrasonic treatment chamber 12 and communicate with the air inlet pipe 61.

[0063] Reference Figure 4 and Figure 6, the air intake pipe 61 is connected to the air supply mechanism 10.

[0064] Air supply mechanism 10 feeds high-pressure gas into air inlet pipe 61. This high-pressure gas is then discharged into ultrasonic treatment chamber 12 through aeration pipe 62. Due to the presence of aeration pipe 62, the high-pressure gas forms tiny bubbles within the raw material in ultrasonic treatment chamber 12. The movement of these bubbles agitates the raw material. Simultaneously, as the air supply from air supply mechanism 10 increases, the pressure within ultrasonic treatment chamber 12 continuously rises.

[0065] Reference Figure 4 and Figure 6 , based on the coordinated arrangement of the air supply mechanism 10 and the aeration mechanism 6, it has the following three functions: Function 1: When the high-pressure gas is oxygen, the aeration mechanism 6 can increase the dissolved oxygen in the raw materials, thereby facilitating the corresponding reaction or fermentation. Function 2: When the high-pressure gas is an inert gas, the aeration mechanism 6 can stir the raw materials, which can further enhance the uniformity of the raw material slurry. Function 3: The pressure inside the ultrasonic treatment chamber 12 continues to increase. When the raw materials in the ultrasonic treatment chamber 12 need to be transported to the cold plasma treatment chamber 13, the high-pressure environment in the ultrasonic treatment chamber 12 will press the raw materials directly into the cold plasma treatment chamber 13, which can realize the transportation of the raw materials and increase the raw material transportation speed.

[0066] Therefore, based on the coordinated arrangement of the aeration mechanism 6, the air supply mechanism 10 and the sensor feedback mechanism 8, the controller can regulate the dissolved oxygen content of the raw material. At the same time, it can also be used to improve the stirring effect of the raw material and can also be used for the transportation of the raw material.

[0067] Reference Figure 4 The gas supply mechanism 10 includes a gas source electromagnetic reversing valve 101, an oxygen source 102, and an inert gas source 103. The oxygen source 102, the inert gas source 103, and the air inlet pipe 61 are all connected to the gas source electromagnetic reversing valve 101. In this embodiment, the gas source electromagnetic reversing valve 101 is a three-position, three-way solenoid valve; the oxygen source 102 is an industrial oxygen concentrator, an oxygen generator, or a liquid oxygen storage tank; and the inert gas source 103 is a nitrogen generator or a high-pressure nitrogen storage tank.

[0068] Reference Figure 4 Under the action of the gas source electromagnetic reversing valve 101, the controller can control the gas source electromagnetic reversing valve 101 to work, which enables the air inlet pipe 61 to be selectively closed or connected to the oxygen source 102 or the inert gas source 103.

[0069] When the air inlet pipe 61 is closed, the aeration mechanism 6 is inoperative. When the air inlet pipe 61 is connected to the oxygen source 102, the aeration mechanism 6 introduces oxygen into the ultrasonic treatment chamber 12. When the air inlet pipe 61 is connected to the inert gas source 103, the aeration mechanism 6 introduces inert gas into the ultrasonic treatment chamber 12. Therefore, based on the configuration of the air supply mechanism 10, the controller can control whether to introduce aeration into the ultrasonic treatment chamber 12. Furthermore, the controller can select whether the gas entering the ultrasonic treatment chamber 12 is oxygen or inert gas.

[0070] Reference Figure 4 and Figure 6 The pressure relief mechanism 7 includes a pressure relief pipe 71, a first pressure relief branch pipe 72, a second pressure relief branch pipe 73 and a pressure relief electromagnetic reversing valve 74. The pressure relief pipe 71 is connected to the upper end of the ultrasonic treatment chamber 12. The pressure relief pipe 71, the first pressure relief branch pipe 72 and the second pressure relief branch pipe 73 are all connected to the pressure relief electromagnetic reversing valve 74, and an automatic pressure relief valve 75 is installed on the first pressure relief branch pipe 72, and a pressure relief control valve 76 is installed on the second pressure relief branch pipe 73.

[0071] Reference Figure 4 Under the action of the pressure relief solenoid reversing valve 74, the pressure relief pipe 71 can selectively connect to the first pressure relief branch pipe 72 or the second pressure relief branch pipe 73. When the pressure relief pipe 71 connects to the first pressure relief branch pipe 72, the automatic pressure relief valve 75 automatically performs the pressure relief function; when the pressure relief pipe 71 connects to the second pressure relief branch pipe 73, the pressure relief function is achieved by controlling the opening and closing of the pressure relief control valve 76. Therefore, based on the configuration of the pressure relief mechanism 7, the controller can select the following two different pressure relief modes according to the function of the aeration mechanism 6: First, when aeration mechanism 6 aerates the raw materials to achieve agitation or increase dissolved oxygen, first pressure relief branch 72 communicates with pressure relief pipe 71, maintaining a stable pressure within ultrasonic treatment chamber 12. Second, when aeration mechanism 6 is used to transport raw materials, second pressure relief branch 73 communicates with pressure relief pipe 71. In this case, without opening pressure relief control valve 76, gas within ultrasonic treatment chamber 12 continuously increases, leading to a continuous increase in internal pressure. This facilitates raw material transport. Upon detecting completion of raw material transport, sensor feedback mechanism 8 actively opens and controls the pressure relief valve to achieve pressure relief.

[0072] Reference Figure 4 In this embodiment, the automatic pressure relief valve 75 adopts a spring-loaded safety valve or a pilot-operated safety valve; the pressure relief control valve 76 adopts an electromagnetic pressure relief valve or an electric regulating valve.

Valve 911 is closed. Subsequently, high-pressure gas source 932 operates, injecting high-pressure gas into the insufflation tube 931. The high-pressure gas then enters the tee tube 91 and carries the supplement in the tee tube 91 into the ultrasonic treatment chamber 12, thereby adding the corresponding supplement to the ultrasonic treatment chamber 12.

The cold plasma instantly destroys the bacterial membrane in the raw materials, achieving heatless sterilization and reducing the impact on the raw materials.

[0083] In this embodiment, the two material delivery control valves 41 on the cold plasma processing chamber 13 are respectively arranged on the secondary material feed pipe 131 and the secondary material discharge pipe 132 , which can realize the material feed and discharge control of the cold plasma processing chamber 13 .

[0100] Since the post-processing chamber 3 is provided with a temperature control mechanism 5, after the fermented raw materials are injected into the post-processing chamber 3, the temperature control mechanism 5 controls the temperature in the post-processing chamber 3 in three stages, so that the raw materials are subjected to flavor post-ripening or enzymatic hydrolysis at three different temperatures in turn, thereby improving the quality of the finished product.

[0101] Reference Figure 1 and Figure 4 In this embodiment, all pipe connections are flanged, facilitating assembly and disassembly of interconnected pipes.

[0102] The implementation principle of the embodiment of the present application is: when fermenting raw materials, the number of fermentation stages of the raw materials and the characteristics of each fermentation stage are determined according to the fermentation characteristics of the raw materials.

[0103] The number of additional fermentation tanks 22 is selected based on the number of fermentation stages. Specifically, when the number of fermentation stages is greater than the number of fermentation tanks 22, additional fermentation tanks 22 are installed; and when the number of fermentation tanks 22 is less than the number of fermentation tanks 22, the number of fermentation tanks 22 does not need to be reduced, and multiple connected fermentation tanks 22 can be selected to achieve the same fermentation stage.

[0104] According to the characteristics of each fermentation stage, the temperature of the corresponding fermentation chamber 22 is regulated, and the corresponding bacterial liquid is added into the supplement injection mechanism 9 of the corresponding fermentation chamber 22.

[0105] During fermentation, the raw materials first pass through the ultrasonic treatment chamber 12, cold plasma treatment chamber 13, and enzymatic hydrolysis chamber 14, sequentially from top to bottom, undergoing pretreatment. Next, the raw materials are transferred from the enzymatic hydrolysis chamber 14 to the bottom-most fermentation chamber 22, where they then pass through all of the fermentation chambers 22, progressing from bottom to top. Each fermentation stage of the raw materials corresponds to at least one fermentation chamber 22. During this process, the raw materials complete all fermentation stages, resulting in the final product. Finally, the raw materials are transferred from the top-most fermentation chamber 22 to the post-processing chamber 3, where they undergo three-stage temperature control, allowing the raw materials to undergo flavor ripening or enzymatic hydrolysis at three different temperatures, resulting in a higher quality finished product.

[0106] Example 2: A fermentation device for food production, referring to Figure 9 This embodiment differs from Example 1 in that the vertical fermentation tower 2 further includes a stirring assembly 26, which includes a stirring motor 261 and a plurality of stirring shafts 262. The stirring motor 261 is mounted within the mounting base 21, and the drive shaft of the stirring motor 261 is vertically arranged. The stirring shafts 262 are arranged in a one-to-one correspondence with the fermentation chambers 22. The stirring shafts 262 are located in the corresponding fermentation chambers 22 and are vertically arranged. Both ends of the stirring shafts 262 are rotatably connected to the fermentation chambers 22. The drive shafts of the stirring motors 261 are coaxially and detachably connected to adjacent stirring shafts 262, and to each other.

[0107] When the stirring motor 261 is working, the stirring motor 261 can drive the plurality of stirring shafts 262 to rotate synchronously, which can realize an active stirring function, thereby improving the stirring effect of the raw materials in the plurality of fermentation chambers 22 .

Therefore, the provision of the detachable connector 263 facilitates the assembly and disassembly of the fermentation chambers 22.

[0113] The sliding mounting members 212 and the fixed mounting members 213 cooperate to allow each fermentation chamber 22 to be independently connected to a plurality of mounting posts 211. If a problem occurs with a fermentation chamber 22, the fixed mounting member 213 and the sliding mounting member 212 on the corresponding fermentation chamber 22 are removed. This allows the fermentation chamber 22 to be directly removed from between two adjacent mounting posts 211, while the other fermentation chambers 22 remain fixed, making replacement and maintenance of the fermentation chambers 22 easier.

[0114] Reference Figure 11 and Figure 12The sliding mounting member 212 includes a fixed sleeve 2121, which is sleeved on the outside of the mounting column 211, and the fixed sleeve 2121 is detachably connected to the mounting column 211.

The fixed plug plate 2132 is plugged into the corresponding slot, and the fixed plug plate 2132 is detachably connected to the fixed plug plate 2132.

[0117] Reference Figure 11 and Figure 12 In this embodiment, the fixed sleeve 2121 and the mounting column 211, the mounting plate 2131 and the fermentation chamber 22, and the movable splint 2122 and the fixed plug plate 2132 are all connected by bolts.

[0118] The implementation principle of the embodiment of the present application is: when there is a problem with the fermentation chamber 22, first, the pipes and wires connected to the outside of the fermentation chamber 22 are removed; secondly, the bolts between adjacent fermentation chambers 22 are removed; then, the detachable connectors 263 between adjacent fermentation chambers 22 are removed; thereafter, the bolts between the fixed plug plate 2132 and the corresponding movable splint 2122 on the fermentation chamber 22 are removed, thereby rotating the movable splint 2122 so that the movable splint 2122 does not interfere with the fermentation chamber 22; finally, the corresponding fermentation chamber 22 can be directly taken out from between the two adjacent fermentation chambers 22.

[0119] Based on this structural design, when a fermentation chamber 22 is damaged, it is not necessary to dismantle all the fermentation chambers 22 above the damaged fermentation chamber 22 from top to bottom, which can reduce the difficulty of replacing or maintaining the damaged fermentation chamber 22. At the same time, it is also convenient to replace a new fermentation chamber 22, ensuring that the fermentation work can be quickly restored to normal.
