[0002] Microbial fermentation refers to a process of converting raw materials into products required by human beings through specific metabolic pathways under suitable conditions by using microorganisms.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figures 1-9As shown, the present application provides a kind of technical scheme of microbial fermentation production line for dairy product, including fermentation device main body 1 and controller 9, fermentation device main body 1 includes fermentation tank 11, drive assembly 2 and stirring assembly 3 are installed on the side of fermentation tank 11, drive assembly 2 is connected with stirring assembly 3, heating assembly 4 is installed in stirring assembly 3, quantitative injection component 5 is installed on the top of fermentation tank 11, fermentation tank 11 output end is connected with bacterial body collection machine 12, bacterial body collection machine 12 output end is respectively installed with concentrator 13 and dryer 6; Bacterial body collection machine 12 can collect bacterial bodies and remove supernatant; Concentrator 13 can improve the purity of bacterial bodies; Dryer 6 can dry bacterial sludge; Therefore, when the device is used, first of all, the raw materials need to be put into fermentation tank 11 through quantitative injection component 5, and the raw materials are preliminarily processed in fermentation tank 11, and then the fermented raw materials are put into bacterial body collection machine 12, and the bacterial bodies in the fermented raw materials are collected by bacterial body collection machine 12, and then the bacterial bodies and bacterial sludge are put into different equipment by bacterial body collection machine 12, the bacterial bodies are placed in concentrator 13 to improve the purity of the bacterial bodies, and the bacterial sludge is put into dryer 6 to form high-activity freeze-dried powder with the rest of the materials, and when used, quantitative injection component 5 will quantitatively inject raw materials into fermentation tank 11 according to the setting, and when the raw materials are in fermentation tank 11, drive assembly 2 will be started to drive stirring assembly 3 to rotate, thereby realizing the stirring of the raw materials and accelerating the fermentation of the raw materials, and in order to create a fermentation environment, the heating assembly 4 in stirring assembly 3 will heat stirring assembly 3 when used, and the inside to the outside of fermentation tank 11 is heated to ferment the raw materials faster, and thus the device can ferment the raw materials faster and produce lactic acid bacteria faster when used.

[0020] As Figure 2 shown, in this embodiment, specifically, stirring assembly 3 includes stirring rod 31, stirring rod 31 is installed on the top of fermentation tank 11 through bearing, drive ring 32 is installed at the bottom of stirring rod 31, drive teeth 33 are arranged on the output surface of drive ring 32, drive teeth 33 are equidistantly installed on drive ring 32, a plurality of dispersion rods 34 are arranged on drive ring 32 and stirring rod 31 respectively, and heating assembly 4 is arranged in drive ring 32 and dispersion rod 34; When in use, the stirring component 3 can stir the raw materials in the fermentation tank 11, accelerate the fermentation of the raw materials, and make it more uniform during the fermentation process. During specific use, the stirring component 3 will be driven by the driving component 2, so that the raw materials in the fermentation tank 11 can be stirred. When the driving component 2 drives the driving ring 32 to rotate through the driving teeth 33, it will drive the stirring rod 31 to rotate together, thereby driving the dispersion rod 34 at the bottom of the driving ring 32. The raw materials in the fermentation tank 11 are evenly broken up and stirred through the dispersion rod 34, and the heating component 4 inside the dispersion rod 34 and the stirring rod 31 can heat the material during the stirring process, thereby realizing heating from the inside to the outside, ensuring the environment for material fermentation.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, specifically, the drive assembly 2 includes a drive motor 21 and a support platform 22. The support platform 22 is installed outside the fermentation tank 11, and the drive motor 21 is installed above the support platform 22. A drive disk 23 is provided at the output end of the drive motor 21. A limit disk 24 is provided inside the fermentation tank 11. A transmission rod 25 is installed on the limit disk 24 through a bearing. A matching disk 26 and multiple groups of drive rods 27 are respectively installed on the transmission rod 25. The drive disk 23 cooperates with the matching disk 26. Multiple groups of drive rods 27 are equidistantly installed on the transmission rod 25. The drive rod 27 cooperates with the drive teeth 33. When the driving assembly 2 of the device is in use, it can drive the stirring assembly 3 to stir the material in the fermentation tank 11. During specific use, the driving motor 21 can drive the driving disk 23 to rotate, and the driving disk 23 is magnetically coupled with the matching disk 26. Therefore, when the driving motor 21 drives the driving disk 23 to rotate, it will drive the matching disk 26 to rotate together. When the matching disk 26 rotates, because the matching disk 26 is installed at one end of the transmission rod 25, it can drive the driving rod 27 to rotate together. Because the driving rod 27 cooperates with the driving tooth 33, it can drive the driving ring 32 to rotate. At this time, the dispersion rods 34 above and below the driving ring 32 will stir the material. At the same time, the driving rod 27 will also stir the material. In conjunction with the breaking rod 74, the device can break up and stir the material from multiple angles and multiple positions to accelerate the fermentation of the material. Because the driving motor 21 of the driving assembly 2 uses magnetic coupling to drive the internal stirring assembly 3, it can ensure the safety of the driving motor 21 when the driving motor 21 is stuck.

[0022] like Figure 6 As shown, in this embodiment, specifically, multiple groups of magnets are respectively provided on the driving disk 23 and the matching disk 26. The multiple groups of magnets are respectively installed on the driving disk 23 and the matching disk 26 at equal distances, and the magnetic pole directions of two adjacent groups of magnets are different; Because the driving disc 23 and the matching disc 26 are respectively provided with a plurality of groups of magnets, the magnets are attracted to each other when the poles are different and repel each other when the poles are the same, and because the poles of the two adjacent groups of magnets of the device are opposite to each other, the driving disc 23 can generate enough attractive force to drive the matching disc 26 when rotating. Because the driving motor 21 of the device is arranged outside the fermentation tank 11, even if the internal part is stuck, the driving motor 21 outside will also be stuck, which can greatly ensure the safety of the driving motor 21 and prevent the driving motor 21 from being overloaded.

[0023] As shown in Figure 2 and Figure 7 , in this embodiment, the heating assembly 4 includes a plurality of heating wires 41, which are equidistantly installed inside the stirring rod 31. The upper end of the stirring rod 31 is provided with a receiving plate 42. The outside of the fermentation tank 11 is provided with a transmitting plate 43. The transmitting plate 43 and the receiving plate 42 each have a group of electrodes. The transmitting plate 43 is connected with the controller 9. The transmitting plate 43 and the receiving plate 42 are electrically connected. The receiving plate 42 is connected with the heating wire 41. The heating assembly 4 of the device can heat the inside of the fermentation tank 11 when in use. Because the heating wires 41 in the heating assembly 4 are respectively installed in the stirring rod 31 and the dispersing rod 34, the inside of the fermentation tank 11 can be heated from the inside to the outside during the operation of the stirring rod 31 and the dispersing rod 34. In specific use, the transmitting plate 43 and the receiving plate 42 each have a group of electrodes. The coupling capacitor is formed between the two through air or medium. When the transmitting electrode applies high-frequency alternating voltage, the alternating electric field will induce displacement current on the receiving electrode, thereby completing energy transmission and realizing power supply to the heating wire 41.

[0024] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 , in this embodiment, the quantitative feeding assembly 5 includes a plurality of feeding pipes 51. The feeding pipe 51 is provided with an electric valve at the connection with the fermentation tank 11. The inner wall of the feeding pipe 51 is provided with a sliding groove 52. The sliding groove 52 is internally provided with a sliding block 53, a pressure sensing plate 54 and a plurality of sensing blocks 55. One end of the sensing block 55 is installed in the sliding groove 52 through a bearing. The other end of the sensing block 55 is provided with a striker 551 and a limiting spring 552. The striker 551 is located between the limiting springs 552. The limiting spring 552 is connected with the controller 9. The striker 551 can impact the pressure sensing plate 54. The sliding block 53 is slidingly installed above the sensing block 55. The side of the sliding block 53 away from the sliding groove 52 is provided with a cover plate 56 through a bearing. The cover plate 56 will descend with the descending of the material in the feeding pipe 51. The quantitative injection assembly 5 of the device can inject different raw materials into the fermentation tank 11 in a quantitative manner during use, and ensures that the raw materials injected each time meet the threshold value, thereby achieving the most perfect fermentation. During use, different raw materials need to be supplemented into each injection pipe 51, and when injecting into the fermentation tank 11, each group of electric valves is opened, and the raw materials in the injection pipe 51 flow into the fermentation tank 11 by themselves. At this time, the total amount of the raw materials decreases, and the cover plate 56 on the raw materials also decreases with the decrease of the raw materials. When the cover plate 56 decreases, the sliding block 53 moves in the sliding groove 52, and the sliding block 53 presses the sensing block 55. Since one end of the sensing block 55 is limited, the other end presses the spring and is embedded in the sliding groove 52. At this time, the striker 551 hits the pressure sensing plate 54, and exerts a force on the pressure sensing plate 54. Therefore, when the controller 9 detects that the pressure sensing plate 54 is stressed, it indicates that the total amount of the raw materials decreases to the current position at this time. Therefore, according to the starting point of the raw materials, the device can accurately determine how much raw material is needed. When the device is replenished, the limiting spring 552 needs to be energized to shrink, thereby pulling the sliding block 53 again, and the replenishment process is completed by turning over the cover plate 56.

[0025] As shown in Figure 3 , in this embodiment, specifically, the drying machine 6 includes a drying box 61, a mixing assembly 7 is installed above the drying box 61, and a plurality of cooling assemblies 8 are installed on the inner wall of the drying box 61. The cooling assembly 8 and the mixing assembly 7 are respectively connected with the controller 9. The mixing assembly 7 can assist the mixing of the bacteria mud and the remaining materials, and the cooling assembly 8 can assist the freeze-drying of the materials. The drying machine 6 of the device can freeze-dry the bacteria mud during use. Specifically, when the treated bacteria mud and the protective agent are put into the drying box 61, the cooling assembly 8 and the mixing assembly 7 process the bacteria mud and the protective agent. The cooling assembly 8 cools the bacteria mud and the protective agent to achieve freeze-drying processing. The mixing assembly 7 can accelerate the mixing of the bacteria mud and the protective agent during freezing, so that the two can be uniformly mixed together to ensure that the final freeze-dried powder can reach the best state.

[0026] As shown in Figure 3 , in this embodiment, specifically, the mixing assembly 7 includes a mixing motor 71, a connecting rod 72 is installed at the output end of the mixing motor 71, a plurality of mixing rods 73 are installed on the connecting rod 72, a scattering rod 74 is installed between the two mixing rods 73 adjacent to each other, the scattering rod 74 is installed between the two mixing rods 73 through bearings at both ends, the scattering rod 74 is composed of two supporting rods, and the two supporting rods are connected through a universal joint. When the mixing assembly 7 of the device is in use, the mixing motor 71 can drive the connecting rod 72 to rotate, thereby driving the mixing rod 73 to rotate. Because a beating rod 74 is provided between the two adjacent groups of mixing rods 73, when the mixing rod 73 rotates, because the two ends of the beating rod 74 are connected to the mixing rod 73 through bearings, and the total length of the beating rod 74 is greater than the vertical length of the two groups of mixing rods 73, the beating rod 74 will rotate with the centrifugal force to mix the bacterial mud, so that the finally formed freeze-dried powder can be more uniform.

[0027] like Figure 9 As shown, in this embodiment, specifically, the cooling assembly 8 includes a heat absorbing plate 81 and a heat releasing plate 82. The heat absorbing plate 81 and the heat releasing plate 82 are respectively composed of semiconductors and metals of different materials. The cooling assembly 8 is connected to the controller 9. The heat absorbing plate 81 is the cold end, and the heat releasing plate 82 is the hot end. The heat absorbing plate 81 is in contact with the drying box 61. When in use, the cooling component 8 of the device can freeze the drying box 61 so that the bacterial mud in the drying box 61 can be freeze-dried. When in use, the heat absorbing plate 81 can absorb the heat of the dryer 6 and gradually cool the dryer 6 to achieve freezing, and the heat releasing plate 82 can discharge the absorbed heat out of the drying box 61.

[0028] like Figure 1 As shown, in this embodiment, specifically, a controller 9 is provided on the side of the fermentation device body 1, the controller 9 is connected to the fermentation device body 1, and a control panel is provided on the controller 9; Because the controller 9 is connected to the fermentation device body 1 , the staff can indirectly control the fermentation device body 1 through the control panel and monitor the fermentation device body 1 to ensure that no unexpected situation occurs during the use of the fermentation device body 1 .

[0029] Working principle: thus, the device in use, first need to put raw materials through quantitative injection assembly 5, put into the fermentation tank 11, through the fermentation tank 11 to raw materials for preliminary processing, after fermentation of raw materials will be put into the bacteria collection machine 12, through the bacteria collection machine 12 will ferment raw material among the bacteria collection, after the bacteria collection machine 12 will be put into different equipment respectively, the bacteria placed in the concentrator 13, in order to improve the purity of bacteria, but need to be put into the dryer 6, cooperate with the rest of the material to form high activity of freeze-dried powder, specific use, quantitative injection assembly 5 will be set according to the quantitative injection of raw materials into the fermentation tank 11, and when the raw materials in the fermentation tank 11, drive assembly 2 will start, thus driving the stirring assembly 3 rotation, in turn realize the stirring of raw materials, accelerate the fermentation of raw materials, in order to create fermentation environment, the stirring assembly 3 of the device in use, its internal heating assembly 4 will be heated to stirring assembly 3, from inside to outside of the fermentation tank 11 heating, in order to faster fermentation of raw materials, in turn the device in use, can faster fermentation of raw materials, faster production of lactic acid bacteria.
