Technical Field
[0001] This invention relates to the field of fermentation equipment technology, specifically a fermentation device for Boletus edulis culture medium. Background Technology
[0002] As an edible fungus with high nutritional and economic value, the artificial cultivation and fermentation production technology of Boletus edulis has gradually attracted attention in recent years. In existing technologies, Boletus edulis cultivation typically employs liquid fermentation. Fermentation devices, as a type of microbial culture apparatus, can provide suitable temperature, pH, and aeration conditions to achieve rapid mycelial proliferation and accumulation of metabolic products. Furthermore, in existing microbial culture fermentation devices, oxygen is typically introduced into the culture medium through mechanical stirring and aeration systems to meet the growth requirements of the fungi, while a temperature control system maintains a stable fermentation environment.
[0003] However, culture media usually contain a certain proportion of organic nutrients, protein components, polysaccharide components, or plant-derived extracts. During fermentation, these substances can easily interact with the metabolites produced during fermentation, causing changes in the surface tension, viscosity, and interfacial state of the liquid.
[0004] Therefore, as the mechanical stirring and aeration systems in traditional microbial culture fermentation devices continue to operate, a relatively stable foam accumulation layer easily forms on the surface of the fermentation broth. Once this foam layer persists, it will lead to a decrease in the efficiency of oxygen passage through the aeration system, and it will also make it difficult for carbon dioxide and volatile metabolites produced during fermentation to escape in a timely manner, thus causing the accumulation of metabolites in local areas.
[0005] Furthermore, during long-term operation, the inner wall area is prone to the adhesion of culture medium components or bacterial metabolites. With the heat conduction of the inner liner of the tank, an adhesion layer or adhesive layer is gradually formed. This adhesion layer can easily cause local heat exchange and deterioration of local mass transfer.
[0006] Therefore, a fermentation device for Boletus culture medium is proposed. Summary of the Invention
[0007] The purpose of this invention is to provide a Boletus culture medium fermentation device to solve the problems in the prior art, such as the easy formation of a relatively stable foam accumulation layer on the surface of the fermentation liquid, which leads to a decrease in the oxygen passage efficiency of the ventilation system, the difficulty in timely escape of carbon dioxide and volatile metabolites generated during fermentation, and the easy formation of an adhesion layer on the sidewall.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a Boletus edulis culture medium fermentation device, comprising a tank, a ventilation ring, a detection rod, a stirring component, a scraping component, a disturbance component, and a breaking component; the stirring component includes a motor and a stirring rod; the stirring rod is driven by the motor and rotates around the center of the tank; the ventilation ring is located at the lower part of the fermentation tank for introducing gas into the fermentation chamber of the tank; the stirring component is located inside the tank and reciprocates periodically with the interior of the tank; the detection rod is located above the tank and extends downward into the fermentation liquid; the scraping component is located inside the tank. The scraping component, driven by a motor, rotates in the opposite direction to the stirring rod to scrape off the adhesive layer on the inner wall of the tank. The disturbance component, along with the stirring rod and the scraping component, is vertically movable and rotates with them. The breaking component is mounted on the disturbance component. The disturbance component always floats above the liquid surface. The middle part of the disturbance component rotates with the stirring rod, while the outer part rotates with the scraping component. When the motor rotates forward, the foam gathers towards the middle part; when the motor rotates in reverse, the foam gathers towards the outer part. The breaking component is used to break the gathered foam.
[0009] Preferably, the scraping assembly includes a rotating ring, a scraper, a disintegrating rod, and a driving component; there are two sets of rotating rings, which are rotatably connected to the upper and lower ends of the inner wall of the tank, respectively; the scraper is fixedly connected between the upper and lower sets of rotating rings, and the scraper is arranged in an equidistant array around the circumference of the rotating ring; the disintegrating rod is fixedly connected between the two sets of rotating rings and is located on the side of the scraper closer to the center of the tank; the driving component is located at the top of the tank; during the rotation of the stirring rod driven by the motor, the driving component will also be driven to rotate, thereby driving the rotating ring and the stirring rod to rotate in opposite directions. During the rotation of the rotating ring, the scraper will be driven to clean the adhesive layer on the inner wall of the tank.
[0010] Preferably, the driving component includes teeth, a sealing box, a gear, an extension rod, a driven wheel, and a driving wheel; the teeth are fixedly connected to the outer ring of the top rotating ring, the sealing box is fixedly connected to the outer wall of the tank, the gear is rotatably connected to the sealing box and meshes with the teeth, the extension rod is rotatably connected to the fixing frame on the tank, the bottom of the extension rod passes through the sealing box and is fixedly connected to the gear, the driven wheel is fixedly connected to the top of the extension rod, and the driving wheel is fixedly connected to the motor output shaft. The driving wheel and the driven wheel are connected by a belt; wherein, the extension rod and the sealing box are in a sealed rotating connection; while the motor drives the stirring rod to rotate, the driven wheel will rotate through the driving wheel and the belt, the driven wheel will drive the extension rod and the gear to rotate, and then the gear will drive the rotating ring to rotate in the opposite direction to the stirring rod through meshing with the teeth.
[0011] Preferably, the diameter of the drive wheel is slightly larger than that of the driven wheel, and the rotational speed of the rotating ring is less than that of the stirring rod. The setting that the diameter of the drive wheel is slightly larger than that of the driven wheel is to increase the rotational speed of the rotating ring and prevent the rotational speed of the rotating ring from being too slow due to excessive differential speed, which would result in an insignificant cleaning effect on the inner wall of the tank. However, the rotational speed of the rotating ring is controlled to be slightly slower than that of the stirring rod, which can effectively prevent the mycelium from being damaged by excessively fast rotation.
[0012] Preferably, the maximum height of the liquid level in the tank is lower than the bottom position of the rotating ring above; thus, the scraper on the rotating ring can clean the foam residue on the side wall of the tank above the liquid level.
[0013] Preferably, the disturbance component includes an annular float, a central blade, a floating box, and an outer peripheral blade; the annular float is slidably connected to the stirring rod and rotates with the stirring rod; the central blade is arranged in an equidistant array around the annular float and is fixedly connected to the annular float; the floating box is simultaneously slidably connected to the decomposition rod and the scraper; the outer peripheral blade is fixedly connected to the side of the floating box facing the center of the tank; both the central blade and the outer peripheral blade are arc-shaped; when the stirring rod rotates forward, the rotating ring will rotate in the opposite direction, and the outer arc surface of the outer peripheral blade will continuously push the foam towards the central blade area, while the inner arc surface of the central blade will gradually gather the foam to the center position of the stirring rod; when the stirring rod rotates in the reverse direction, the rotating ring will rotate forward, and the foam will be pushed by the outer arc surface of the central blade towards the outer peripheral blade, and then collected by the inner arc surface of the outer peripheral blade towards the side wall of the tank.
[0014] Preferably, a gap N is formed between the rotation ranges of the middle blade and the outer blade, and the detection rod is located within the gap N region, which can effectively prevent the rotation of the middle blade and the outer blade from interfering with the detection rod. Furthermore, the segmented arrangement of the agitation assembly with middle blade and outer blade can effectively improve the adhesion between the blade and the liquid surface during agitation, and is easier to maintain compared to the integral type.
[0015] Preferably, the breaking component includes a through-hole, an inlet plate, a progressive plate, and breaking spikes; the through-hole is located near the root of each group of middle blades and outer peripheral blades; the inlet plate is located on the inner arc surface side of the through-hole, and the inlet plate is arranged in an equidistant array, with one end fixedly connected to the inner arc surface of the middle blade and the other end extending outward at an angle; the progressive plate is located on the outer arc surface side of the through-hole, and the number of progressive plates is the same as that of the inlet plate, with one end fixedly connected to the outer arc surface of the middle blade and the other end extending outward at an angle. The foam is inclined outwards and extended; multiple sets of the breaking spikes are provided, which are fixedly connected to the inner sides of the inlet plate and the advancing plate respectively; when the stirring rod rotates forward and the rotating ring rotates backward, the foam is pushed by the outer arc surface of the outer peripheral blade and the advancing plate, moves towards the middle blade, and enters the inlet plate position along its inner arc surface to accumulate, where it is punctured by the breaking spikes; when the stirring rod rotates backward and the rotating ring rotates forward, the foam is pushed by the outer arc surface of the middle blade and the advancing plate, moves towards the outer peripheral blade, and enters the inlet plate position along its inner arc surface to accumulate, where it is punctured by the breaking spikes.
[0016] Preferably, the puncturing spikes are arranged in an array of multiple metal spikes surrounding a columnar rod, and the height of the puncturing spikes is the same as the height of the entry plate and the advancement plate, so that the puncturing spikes can completely puncture the foam accumulated at the entry plate.
[0017] Preferably, the ends of the progressive plates are arranged in a progressive manner, and the area covered by the outward extension of the ends of each group of progressive plates can cover part of the area of the next group of progressive plates; thus, when the bubble is pushed to move by the outer arc surface of the middle blade or the outer peripheral blade, it can be ensured that the bubble continuously passes through the progressive plates and is continuously transported, preventing the bubble from getting stuck at the passage during the pushing process.
[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention incorporates a disturbance component and a defoaming component. The central blades of the disturbance component rotate with the stirring rod, while the outer blades rotate in the opposite direction with the scraping component. The periodic forward and reverse rotation of the motor causes foam to circulate and gather between the center and edge of the liquid surface. Simultaneously, entry and advancement plates with defoaming spikes are installed on the central and outer blades. When the foam gathers to the base of the blades, the defoaming spikes continuously and completely puncture the accumulated foam. This dynamic defoaming mechanism effectively prevents foam from accumulating stably in a certain area of the liquid surface for extended periods, avoiding obstruction of oxygen flow through the ventilation ring. This ensures that oxygen can efficiently and evenly pass through the liquid surface into the fermentation broth, while also promoting the timely escape of carbon dioxide and volatile metabolites generated during fermentation, preventing localized accumulation of metabolites, thereby significantly improving fermentation efficiency and uniformity.
[0019] 2. This invention utilizes a scraping assembly consisting of a rotating ring, a scraper, a decomposition rod, and a driving component. While the stirring rod is driven by a motor, the scraper rotates in the opposite direction to the stirring rod via a drive wheel, belt, driven wheel, extension rod, and gears. This continuously scrapes away the adhesive layer on the inner wall of the tank, preventing the formation of a wall-attached layer due to the adhesion of culture medium components or bacterial metabolites, thus avoiding localized deterioration of heat and mass transfer. Simultaneously, the rotating decomposition rod further disperses and disperses the scraped adhesive layer, preventing its re-adhesion, thereby effectively maintaining good heat and mass transfer conditions on the inner wall of the tank.
[0020] 3. This invention sets the disturbance component as a ring float box and a floating box that slide up and down with the stirring rod and the scraping component respectively, so that the middle blade and the outer blade always float above the liquid surface and can automatically adjust according to the liquid level to ensure effective contact with the foam layer; at the same time, a gap N is formed between the rotation range of the middle blade and the outer blade, and the detection rod is set in the gap area, which effectively prevents interference between the rotating component and the detection rod.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1 to 7 The present invention provides a fermentation device for Boletus culture medium, the technical solution of which is as follows: Reference Figure 1 and Figure 2 A fermentation device for Boletus edulis culture medium includes a tank 1, an aeration ring 2, a detection rod 3, a stirring component 4, a scraping assembly 5, a disturbance assembly 6, and a breaking assembly 7. The stirring component 4 includes a motor 41 and a stirring rod 42. The stirring rod 42 is driven by the motor 41 and rotates around the center of the tank 1. The aeration ring 2 is located at the lower part of the fermentation tank 1 to introduce gas into the fermentation chamber of the tank 1. The stirring component 4 is located inside the tank 1 and rotates reciprocally periodically with the interior of the tank 1. The detection rod 3 is located above the tank 1 and extends downward into the fermentation liquid. The scraping assembly 5 is located on the inner wall of the tank 1. Driven by motor 41, the stirring rod 42 rotates in the opposite direction to scrape off the adhesive layer on the inner wall of tank 1. The agitation component 6 is vertically movable with the stirring rod 42 and the scraping component 5, and rotates with the stirring rod 42 and the scraping component 5. The breaking component 7 is disposed on the agitation component 6. The agitation component 6 always floats above the liquid surface. The middle part of the agitation component 6 rotates with the stirring rod 42, and the outer part rotates with the scraping component 5. When the motor 41 rotates forward, the foam gathers towards the middle part, and when the motor 41 rotates in reverse, the foam gathers towards the outer part. The breaking component 7 is used to break the gathered foam. During operation, motor 41 drives stirring rod 42 to rotate, using the stirring blades on stirring rod 42 to agitate the culture medium solution in tank 1. Simultaneously, venting ring 2 introduces oxygen from the bottom of tank 1 into the liquid to meet the needs of bacterial growth. While motor 41 drives stirring rod 42 to rotate, it also drives scraping component 5 to rotate in the opposite direction to scrape off the adhesive layer on the side wall of tank 1. Furthermore, stirring rod 42 will adjust its rotation direction periodically to ensure optimal stirring. While stirring rod 42 and scraping component 5 rotate, agitation component 6 will always float above the liquid surface, with its middle and outer portions rotating simultaneously with stirring rod 42 and scraping component 5, respectively. When rotating in the forward direction, the scraping component 5 will rotate in the reverse direction. At this time, the foam on the liquid surface will be pushed towards the center of the tank 1 by the outer periphery of the disturbance component 6 and gathered by the middle part. When the stirring rod 42 rotates in the reverse direction, the scraping component 5 will rotate in the forward direction. At this time, the foam on the liquid surface will be pushed outward along the middle part of the disturbance component 6 and gathered by the outer periphery. Whether it gathers towards the middle part or the outer periphery, it will be punctured by the breaking component 7. Thus, with the reciprocating periodic rotation of the stirring rod 42, the disturbance component 6 can push the foam to move continuously in the page area and be gradually broken by the breaking component 7. This can effectively prevent the foam from accumulating on the liquid surface or staying in the same position for a long time, affecting the efficiency and uniformity of oxygen passage.
[0025] Reference Figure 3 and Figure 4 The scraping assembly 5 includes a rotating ring 51, a scraper 52, a disintegrating rod 53, and a driving component 54. Two sets of rotating rings 51 are provided, rotatably connected to the upper and lower ends of the inner wall of the tank 1, respectively. The scraper 52 is fixedly connected between the upper and lower sets of rotating rings 51, and the scraper 52 is arranged in an equidistant array around the circumference of the rotating rings 51. The disintegrating rod 53 is fixedly connected between the two sets of rotating rings 51 and located on the side of the scraper 52 closest to the center of the tank 1. The driving component 54 is located at the top of the tank 1. During the rotation of the stirring rod 42 driven by the machine 41, the driving component 54 will also be driven to rotate. In turn, the driving component 54 drives the rotating ring 51 to rotate in the opposite direction to the stirring rod 42. During the rotation of the rotating ring 51, the scraper 52 will be driven to clean the adhesive layer on the inner wall of the tank 1, so as to prevent the local adhesive layer from affecting the heat exchange efficiency between the bacterial liquid and the inner wall of the tank 1. At the same time, the decomposition rod 53 will also rotate, and cooperate with the scraper 52 to decompose and disperse the scraped adhesive layer, so as to prevent the scraped adhesive layer from immediately adhering to the inner wall again.
[0026] Reference Figure 3The driving component 54 includes a tooth 541, a sealing box 542, a gear 543, an extension rod 544, a driven wheel 545, and a driving wheel 546. The tooth 541 is fixedly connected to the outer ring of the top rotating ring 51. The sealing box 542 is fixedly connected to the outer wall of the tank body 1. The gear 543 is rotatably connected to the sealing box 542, and the gear 543 meshes with the tooth 541. The extension rod 544 is rotatably connected to the fixing frame on the tank body 1. The bottom of the extension rod 544 passes through the sealing box 542 and is fixedly connected to the gear 543. The driven wheel 545... 5 is fixedly connected to the top of the extension rod 544. The drive wheel 546 is fixedly connected to the output shaft of the motor 41. The drive wheel 546 and the driven wheel 545 are connected by a belt. The extension rod 544 and the sealing box 542 are in a sealed rotational connection. When the motor 41 drives the stirring rod 42 to rotate, the driven wheel 546 and the belt drive driven wheel 545 will rotate. The driven wheel 545 will drive the extension rod 544 and the gear 543 to rotate. Then, the gear 543 will drive the rotating ring 51 to rotate in the opposite direction to the stirring rod 42 through meshing with the teeth 541.
[0027] Reference Figure 3 The diameter of the drive wheel 546 is slightly larger than that of the driven wheel 545, and the rotation speed of the rotating ring 51 is less than that of the stirring rod 42. The purpose of setting the diameter of the drive wheel 546 to be slightly larger than that of the driven wheel 545 is to increase the rotation speed of the rotating ring 51 and prevent the rotation speed of the rotating ring 51 from being too slow due to excessive differential speed, which would result in an insignificant cleaning effect on the inner wall of the tank 1. However, the rotation speed of the rotating ring 51 is controlled to be slightly slower than that of the stirring rod 42, which can effectively prevent the mycelium from being damaged by excessively fast rotation speed.
[0028] Reference Figure 3 The maximum height of the liquid level in the tank 1 is lower than the bottom position of the rotating ring 51 above; thus, the scraper 52 on the rotating ring 51 can clean the foam residue on the side wall of the tank 1 above the liquid level.
[0029] Reference Figure 5 and Figure 6The disturbance component 6 includes an annular float 61, a central blade 62, a floating box 63, and an outer peripheral blade 64. The annular float 61 is slidably connected to the stirring rod 42 and rotates with the stirring rod 42. The central blade 62 is arranged in an equidistant array around the annular float 61 and is fixedly connected to the annular float 61. The floating box 63 is slidably connected to both the decomposition rod 53 and the scraper 52. The outer peripheral blade 64 is fixedly connected to the side of the floating box 63 facing the center of the tank 1. Both the central blade 62 and the outer peripheral blade 64 are arc-shaped. When the stirring rod 42 rotates clockwise and the rotating ring 51 rotates counterclockwise, the outer arc surface of the outer peripheral blade 64 will continuously... The foam is pushed towards the central blade 62 area. The inner arc surface of the central blade 62 will gradually gather the foam to the center of the stirring rod 42 for collection. When the stirring rod 42 reverses and the rotating ring 51 rotates in the forward direction, the foam is pushed by the outer arc surface of the central blade 62 towards the outer peripheral blade 64, and then collected by the inner arc surface of the outer peripheral blade 64 towards the side wall of the tank 1. This can realize the regional rotation collection of foam, prevent the foam from staying in one position for a long time and affecting the oxygen passage efficiency of that area, and effectively prevent the carbon dioxide and volatile metabolites produced in a certain area during fermentation from escaping in time, thus preventing the accumulation of metabolites in a local area.
[0030] Reference Figure 6 A gap N is formed between the rotation range of the middle blade 62 and the outer peripheral blade 64. The detection rod 3 is located in the gap N area, which can effectively prevent the rotation of the middle blade 62 and the outer peripheral blade 64 from interfering with the detection rod 3. Moreover, the segmented arrangement of the agitation assembly with the middle blade 62 and the outer peripheral blade 64 can effectively improve the adhesion between the blade and the liquid surface during agitation. Compared with the integral type, it is easier to maintain.
[0031] Reference Figure 5 and Figure 7The breaking component 7 includes a passage 71, an inlet plate 72, a advancing plate 73, and breaking spikes 74. The passage 71 is located near the root of each group of middle blades 62 and outer peripheral blades 64. The inlet plate 72 is located on the inner arc side of the passage 71, and the inlet plate 72 is arranged in an equidistant array, with one end fixedly connected to the inner arc surface of the middle blade 62 and the other end extending outward at an angle. The advancing plate 73 is located on the outer arc side of the passage 71, and the number of advancing plates 73 is the same as that of the inlet plate 72. The advancing plate 73 is fixedly connected to the outer arc surface of the middle blade 62 with one end fixedly connected to the other end extending outward at an angle. Multiple groups of breaking spikes 74 are provided, respectively fixedly connected to the inner sides of the inlet plate 72 and the advancing plate 73. When the stirring rod 42 rotates clockwise, the rotating ring 51... When the rotation is reversed, the foam will be pushed layer by layer by the advancing plates 73 on the outer peripheral blades 64 and by the outer arc surface of the outer peripheral blades 64, moving towards the middle blades 62. Eventually, it will enter the entry plate 72 of the middle blades 62 along the inner arc surface of the middle blades 62 and accumulate there. As the middle blades 62 rotate, the breaking spikes 74 will also puncture some of the foam. When the stirring rod 42 rotates in reverse and the rotating ring 51 rotates in the forward direction, the foam will again be pushed layer by layer by the advancing plates 73 on the middle blades 62 and by the outer arc surface of the middle blades 62, moving towards the outer peripheral blades 64. Eventually, it will enter the entry plate 72 of the outer peripheral blades 64 along the inner arc surface of the outer peripheral blades 64 and accumulate there. It will then be punctured by the breaking spikes 74 on the outer peripheral blades 64, thus preventing excessive foam accumulation.
[0032] Reference Figure 7 The puncturing spikes 74 are arranged in the form of multiple sets of metal spikes surrounding a columnar rod array, and the height of the puncturing spikes 74 is the same as the height of the entry plate 72 and the advancement plate 73, so that the puncturing spikes 74 can completely puncture the foam accumulated at the entry plate 72.
[0033] Reference Figure 7 The ends of the progressive plates 73 are arranged in a progressive manner, and the area covered by the outward extension of the ends of each group of progressive plates 73 can cover part of the area of the next group of progressive plates 73; thus, when the bubble is pushed by the outer arc surface of the middle blade 62 or the outer peripheral blade 64, it can be ensured that the bubble continuously passes through the progressive plates 73 and is continuously transported, preventing the bubble from getting stuck at the passage 71 during the pushing process.
[0034] Working principle: When the device is working, the motor 41 is started first, which drives the stirring rod 42 to rotate continuously in the center of the tank 1. The stirring blades then stir the culture medium liquid evenly. At the same time, the ventilation ring 2 at the bottom of the tank 1 introduces oxygen into the fermentation liquid, providing the necessary dissolved oxygen for the growth of bacteria.
[0035] While the stirring rod 42 rotates, the drive component 54, composed of the drive wheel 546, belt, driven wheel 545, extension rod 544 and gear 543, drives the scraping assembly 5 to rotate in the opposite direction to the stirring rod 42. This causes the scraper 52 to scrape off the adhesive layer on the inner wall of the tank 1, preventing it from affecting the heat exchange efficiency. The decomposition rod 53, which rotates along with it, further breaks up and disperses the scraped adhesive layer, preventing it from re-adhering.
[0036] As the stirring rod 42 and the scraping assembly 5 begin to rotate, the disturbance assembly 6 also enters the working state. The annular float box 61 rotates with the stirring rod 42 and floats up and down, and the float box 63 rotates with the scraping assembly 5 and floats up and down, so that the middle blade 62 and the outer peripheral blade 64 always float above the liquid surface and can automatically adjust according to the liquid level to ensure effective contact with the foam layer. During operation, the motor 41 continuously adjusts its rotation direction according to a set cycle. When the motor 41 rotates forward, the stirring rod 42 rotates forward and the scraping component 5 rotates in reverse. At this time, the outer arc surface of the outer peripheral blades 64 pushes the foam towards the center of the tank 1, while the inner arc surface of the middle blades 62 gathers and concentrates the foam near the center of the stirring rod 42. When the motor 41 rotates in reverse, the stirring rod 42 rotates in reverse and the scraping component 5 rotates forward. At this time, the outer arc surface of the middle blades 62 pushes the foam towards the periphery of the tank 1, while the inner arc surface of the outer peripheral blades 64 gathers and concentrates the foam near the center of the stirring rod 42. The foam is then gathered and concentrated near the side wall of the tank 1. Regardless of whether the foam is gathered to the center or the side wall, when the middle blade 62 or the outer peripheral blade 64 rotates to the foam accumulation area, the foam will enter the passage 71 area along the entry plate 72 set at the root of the blade. At this time, the breaking spikes 74 fixed to the inside of the entry plate 72 and the advancing plate 73 will continuously puncture the accumulated foam in a full-coverage manner. The layered advancing structure at the end of the advancing plate 73 ensures that the foam moves continuously during the pushing process and does not get stuck. Finally, as the motor 41 periodically switches between forward and reverse rotation, the foam repeatedly gathers and is continuously broken between the center and edge of the liquid surface, effectively preventing the foam from accumulating in a certain area for a long time. This ensures that the oxygen introduced by the ventilation ring 2 can pass through the liquid surface efficiently and evenly, avoiding the accumulation of local metabolic products.
[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
