Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fermented soybean meal, in particular to a fermented soybean meal production equipment and a production method thereof. BACKGROUND

[0002] In the process of fermenting soybean meal to produce water and fertilizer, it is necessary to stir the soybean meal to ensure that the soybean meal, fermentation agent and water are fully mixed, and the fermentation agent is evenly distributed in the fermentation tank, so that each part can fully contact the fermentation agent, thereby improving the fermentation efficiency and promoting the contact between oxygen and microorganisms and preventing clumping and local overheating.

[0003] Publication No. CN117844618B discloses a fermented soybean meal production equipment and a production method thereof, which aims to make the transmission belt drive the soybean meal on it to fluctuate or vibrate, thereby facilitating more effective mixing of the liquid inoculum on the surface of the soybean meal, and ensuring more uniform mixing of the liquid inoculum, microorganisms and soybean meal, and promoting uniform fermentation.

[0004] In summary, the existing technology has the following problems: The existing fermented soybean meal equipment usually uses a stirring rod to stir the soybean meal to make it fully contact with the bacterial liquid, but the continuous rotation of the stirring rod for stirring can easily cause over-stirring and damage to the bacterial population. If the stirring is stopped, the soybean meal will naturally fall and pile up, affecting the contact with the bacterial liquid and thus affecting the fermentation effect. Referring to the above application file, the bacterial liquid is contacted with the soybean meal by spraying, which can easily cause waste of the bacterial liquid. Moreover, the gas is directly blown to the surface of the soybean meal by compression, which can easily blow away the gas on the surface of the soybean meal. This not only cannot increase the contact between the soybean meal and oxygen, but also can affect the contact between the bacterial liquid and the soybean meal, which has certain disadvantages. To solve the above problems, a fermented soybean meal production equipment and a production method thereof are proposed. SUMMARY

[0005] To achieve the above purpose, the present application is implemented by the following technical scheme: a fermented soybean meal production equipment, comprising a tank body, further comprising a rotating groove opened in the inner wall of the bottom of the tank body, an auxiliary mechanism arranged in the tank body and used for assisting the fermentation of soybean meal, and a cleaning mechanism arranged in the tank body and used for cleaning the soybean meal attached to the inner side wall of the tank body, and the cleaning mechanism and the auxiliary mechanism are linked.

When the first gear ring and the second gear ring are engaged, the first rubber ring and the second rubber ring are in a mutually squeezed state.

[0009] Furthermore, the blocking assembly includes: A first retaining ring is fixedly sleeved on an inner wall of one side of the second mounting ring located inside the tank body; The second retaining ring is fixedly sleeved on the side wall of the rotating shaft. A rubber ring is fixedly provided between the inner wall of the first retaining ring and the outer wall of the second retaining ring to seal between the second mounting ring and the rotating shaft.

[0010] Furthermore, the inner wall of the tank body is provided with an installation groove for installing the installation sleeve; The rotating shaft is designed to be hollow so that the air guide tube extends along the inner wall of the rotating shaft into the plate body.

[0011] Furthermore, the limiting mechanism includes: The casing is fixedly mounted on the top inner wall of the tank body, and a guide hole is opened at the bottom of the casing. The bottom inner wall of the casing is designed to be arc-shaped, and the curvature of the bottom inner wall of the casing gradually increases from away from the guide hole to close to the guide hole; The tube body is fixed on the top of the tank body and extends into the casing. A filter cartridge is fixed on one end of the tube body located in the casing. A baffle is fixed on the bottom of the filter cartridge. The side wall diameter of the baffle is larger than the inner wall diameter of the guide hole and the outer wall diameter of the filter cartridge, and a gap is left between the bottom of the baffle and the bottom inner wall of the casing.

[0012] Furthermore, the scraping mechanism includes: The arc-shaped plate is lifted and arranged in the tank body, and ear plates are fixed on both sides of the top of the arc-shaped plate, and a movable sleeve is fixed on the bottom of the ear plate. A scraper ring is fixed on the inner side of the bottom of the movable sleeve, and the outer wall of the scraper ring is in contact with the inner wall of the tank body; The movable groove is opened on both sides of the inner wall of the tank body. The top inner wall and the bottom inner wall of the movable groove are fixed with a rod body. The side wall of the rod body is sleeved on the inner wall of the movable sleeve, and the top of the ear plate is opened with a through hole for sleeved with the rod body. The side wall of the rod body and the top of the ear plate are sleeved with springs to make the scraper ring tend to move downward.

[0013] Furthermore, a support plate is fixedly provided at the middle end of the side wall of the rotating shaft, which is located on the inner side of the plate body and is designed to be inclined so that the support plate contacts the arc plate before the plate body, thereby causing the scraper ring to move upward in the process of the support plate and the plate body successively contacting and pressing against the arc plate.

[0014] The present invention also provides a production method of a fermented soybean meal production device, which uses the fermented soybean meal production device, and the method comprises the following steps: S1: The auxiliary mechanism is driven by the driving mechanism to rotate, thereby turning over the soybean meal accumulated at the bottom of the inner wall of the tank. As the auxiliary mechanism continues to rotate, the soybean meal comes into contact with the bacterial liquid to assist the fermentation of the soybean meal; S2: During the rotation of the auxiliary mechanism, oxygen is transported into the plate body and discharged along the nozzle, so that the oxygen contacts the soybean meal and the bacterial liquid, further assisting the fermentation of the soybean meal.

[0015] The present invention provides a fermented soybean meal production device and a production method thereof. Compared with the prior art, it has the following advantages: 1. The present invention flips the plate to scoop up the soybean meal and mix it with the bacterial solution. Compared with traditional mixing using a stirring rod, the mixing action is lighter, thus avoiding the problem of damaging the bacterial community due to excessive stirring angles in traditional methods, which affects fermentation. In addition, the soybean meal falls naturally during the flipping of the plate, so that the soybean meal slowly falls into the bacterial solution, thereby ensuring sufficient contact between the bacterial solution and the soybean meal.

[0016] 2. The present invention provides a first arcuate groove and an arcuate surface to make the inner side of the plate uneven, thereby preventing excessive and rapid falling of soybean meal, thereby preventing the soybean meal from agglomerating and falling rapidly, and further ensuring sufficient contact between the soybean meal and the bacterial solution. In addition, the guide holes are provided to allow the bacterial solution to disperse the soybean meal on the inner side of the plate, preventing the soybean meal from accumulating on the inner side of the plate. This improves the mixing effect and prevents the accumulation of soybean meal on the inner side of the plate from affecting the next use.

[0017] 3. The present invention discharges gas through the air duct and nozzle to the inner side of the plate body through the air duct, thereby facilitating contact between oxygen, soybean meal and bacterial liquid. Furthermore, in conjunction with the restriction mechanism, the exhaust of oxygen can be restricted while simultaneously allowing the exhaust of carbon dioxide. This allows the tank body to quickly maintain the required oxygen concentration for soybean meal fermentation, further improving the efficiency of soybean meal fermentation. Furthermore, by blowing gas to the inner side of the plate body, the soybean meal on the inner side of the plate body is dispersed, facilitating mixing with oxygen and bacterial liquid, while reducing the amount of soybean meal accumulated on the inner side of the plate body.

[0018] 4. The present invention uses a driving mechanism to slowly rotate the plate body to reduce the impact of the flow of bacterial liquid on the soybean meal entering the inner side of the plate body. In conjunction with the buffer mechanism, the plate body is conveniently rotated in contact with the inner wall of the rotating groove, so that the soybean meal on the inner wall of the bottom of the tank body can be scooped up to ensure full contact between the soybean meal and the bacterial liquid.

[0019] 5. The present invention reduces the total amount of gas in the tank through a restricting mechanism while retaining oxygen in the tank, thereby maintaining the required oxygen concentration for soybean meal fermentation in the tank, facilitating fermentation. The baffle facilitates gas filtration while preventing bacterial liquid and other substances from contacting the filter cartridge, thereby preventing soybean meal and other substances in the bacterial liquid from clogging the filter cartridge and affecting filtration.

[0020] 6. The present invention uses a scraping mechanism and an auxiliary mechanism to scrape soybean meal and other materials attached to the inner wall of the tank body, so that the soybean meal falls into the bacterial solution, thereby avoiding uneven distribution of materials in the tank due to excessive soybean meal attached to the inner wall of the tank body, which affects the uniformity of fermentation. Materials attached to the tank body may affect the temperature during the fermentation process, thereby affecting the fermentation effect. In addition, materials attached to the tank body are prone to breeding bacteria and mold, thus avoiding hygiene problems. When the abutting plate and the plate body contact the arc plate alternately, the arc plate moves downward under the action of the spring to knock the plate body, thereby causing the plate body to shake so that the soybean meal inside the plate body falls off.

[0023] 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.

[0024] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 11 A fermented soybean meal production equipment includes a tank body 1, a rotating groove 8 opened on the inner wall of the bottom of the tank body 1, an auxiliary mechanism 4 rotatably arranged in the tank body 1 and used to assist soybean meal fermentation, and a scraping mechanism 2 arranged in the tank body 1 for cleaning soybean meal attached to the inner wall of the tank body 1, and the scraping mechanism 2 and the auxiliary mechanism 4 are arranged in a linkage manner.

[0025] See also Figure 5 and Figure 6 , the auxiliary mechanism 4 includes: The plate 41 is rotatably mounted on the inner wall of the tank 1 and is designed in the shape of a quarter hollow sphere. The inner wall of the rotating groove 8 is designed in the shape of a hemispherical groove, so that when the plate 41 rotates, the soybean meal at the bottom of the inner wall of the rotating groove 8 is turned over. The outer wall of the tank 1 is provided with a driving mechanism 6 for driving the plate 41 to rotate. The connection between the driving mechanism 6 and the plate 41 is provided with a buffer mechanism 3 for providing a buffer space for the plate 41. The nozzles 43 are spaced apart on the inner side of the plate 41. An air guide tube 47 extending to the outside of the tank body 1 is fixedly provided on the top of the plate 41, and the exhaust end of the air guide tube 47 is connected to the air inlet end of the nozzle 43 to allow oxygen to come into contact with the soybean meal during the turning process. A limiting mechanism 7 for limiting the discharge of oxygen from the tank body 1 is provided on the top inner wall of the tank body 1.

[0026] The auxiliary mechanism 4 also includes: First arcuate grooves 44 are spaced apart on the inner side of the plate body 41. An arcuate surface 42 is provided on the inner side of the plate body 41 and outside the first arcuate grooves 44. The inner side height of the arcuate surface 42 is greater than the inner side height of the first arcuate grooves 44 to limit the speed at which soybean meal is dumped out of the plate body 41. Nozzles 43 are fixed to the inner sidewall of the first arcuate grooves 44. Guide holes 46 are spaced apart and formed on the inner wall of the first arc-shaped groove 44 to prevent soybean meal from adhering to the inner side of the plate 41 ; The second arc-shaped grooves 45 are formed at the inner top and the inner bottom of the plate body 41 .

[0027] In specific implementation, the soybean meal needs to be stirred during the fermentation process so that the soybean meal is fully in contact with the bacterial solution, etc., to ensure the fermentation effect. To this end, the plate body 41 rotates along the inner wall of the rotating groove 8. When the plate body 41 enters the rotating groove 8, the soybean meal accumulated on the inner wall of the bottom of the tank body 1 is shoveled up. As the plate body 41 continues to rotate, the soybean meal is shoveled to the inner side of the plate body 41. During the turning process of the plate body 41, the soybean meal is poured out so that the soybean meal is fully in contact with the bacterial solution, etc., thereby assisting the fermentation of the soybean meal. By flipping the plate 41 to scoop up the soybean meal and mix it with the bacterial solution, the mixing action is lighter than that of conventional mixing by a stirring rod, thereby avoiding damage to the bacterial community due to excessive stirring and affecting fermentation. In addition, by allowing the plate 41 to fall naturally during the flipping process, the soybean meal slowly falls into the bacterial solution, thereby ensuring sufficient contact between the bacterial solution and the soybean meal.

[0028] By providing the first arcuate groove 44 and the arcuate surface 42, the inner side of the plate body 41 is made uneven, thereby forming a step-like structure, which can block the falling of part of the soybean meal during the turning process of the plate body 41, thereby slowing down the speed of the soybean meal falling from the inner side of the plate body 41. Moreover, since the soybean meal is soaked in the bacterial liquid, a certain buoyancy is generated on the soybean meal, thereby further slowing down the speed of the soybean meal falling from the plate body 41. When the soybean meal enters the inner side of the plate body 41 and during the turning process of the plate body 41, the soybean meal on the inner surface of the plate body 41 falls first, and part of the soybean meal is blocked by the arcuate surface 42 and The stair-like structure between the first arcuate grooves 44 blocks the soybean meal that is retained in the first arcuate grooves 44. As the flipping angle of the plate body 41 gradually increases, the blocked soybean meal falls, thereby preventing excessive and rapid falling of the soybean meal and further ensuring sufficient contact between the soybean meal and the bacterial solution. In addition, by providing the guide holes 46, the bacterial solution can enter the inner side of the plate body 41 through the guide holes 46 during the flipping process of the plate body 41, thereby dispersing the soybean meal inside the plate body 41 and preventing the soybean meal from accumulating inside the plate body 41. This improves the mixing effect while preventing the accumulation of soybean meal inside the plate body 41 from affecting the next use.

[0029] By providing the second arc-shaped groove 45 , the thickness of the top and bottom of the plate body 41 is made thinner than the entire plate body 41 , so as to facilitate the soybean meal to enter the inner side of the plate body 41 .

[0030] By connecting the air duct 47 to an external gas pipeline, etc., the gas is discharged along the air duct 47 and the nozzle 43 to the inner side of the plate body 41, so that the oxygen can contact the soybean meal and the bacterial liquid. In cooperation with the limiting mechanism 7, the discharge of oxygen can be limited while the carbon dioxide can be discharged, so that the oxygen concentration required for soybean meal fermentation can be quickly maintained in the tank body 1, further improving the efficiency of soybean meal fermentation. In addition, by blowing the gas to the inner side of the plate body 41, the soybean meal inside the plate body 41 is easily blown away, facilitating mixing with oxygen and bacterial liquid, while reducing the amount of soybean meal accumulated inside the plate body 41.

[0031] During the process of rotating the plate 41 to scoop up the soybean meal and mix it with the bacterial solution, the driving mechanism 6 drives the plate 41 to rotate slowly to reduce the impact of the flow of the bacterial solution on the soybean meal entering the inner side of the plate 41. In addition, in cooperation with the buffer mechanism 3, the plate 41 is conveniently rotated in contact with the inner wall of the rotating groove 8, so that the soybean meal on the inner wall of the bottom of the tank body 1 can be scooped up, so that the soybean meal and the bacterial solution are fully in contact.

[0032] See also Figure 4 , the driving mechanism 6 includes: The servo motor 61 is fixed to the outer wall of the tank body 1. The output shaft of the servo motor 61 is fixed with a rotating shaft 62 extending into the tank body 1 through a coupling, so that the servo motor 61 drives the plate body 41 to rotate through the rotating shaft 62 and the buffer mechanism 3, and the rotating shaft 62 is rotatably connected to the tank body 1.

[0033] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the buffer mechanism 3 includes: The first mounting ring 37 is fixedly mounted on the side wall end of the rotating shaft 62 . The first rubber ring 36 is fixedly mounted on the outer wall of the first mounting ring 37 . The first gear ring 38 is fixedly mounted on the outer wall of the first mounting ring 37 and on both sides of the first rubber ring 36 .

[0034] The buffer mechanism 3 also includes: The mounting sleeve 34 is fixedly mounted on the inner wall of the tank body 1. A bearing 33 is provided on the inner wall of the mounting sleeve 34. The outer wall of the outer ring of the bearing 33 is fixedly connected to the inner wall of the mounting sleeve 34. A second mounting ring 31 extending into the tank body 1 is fixedly sleeved on the inner wall of the inner ring of the bearing 33. The outer wall of one side of the second mounting ring 31 located inside the tank body 1 is fixedly connected to the end of the plate body 41. A blocking assembly 32 is provided on the inner wall of one side of the second mounting ring 31 located inside the tank body 1. A third mounting ring 35 is fixedly sleeved on the inner wall of the second mounting ring 31. The second rubber ring 391 is fixedly mounted on the inner wall of the third mounting ring 35. The second gear ring 39 is fixedly mounted on the inner wall of the third mounting ring 35 and on both sides of the second rubber ring 391. The second gear ring 39 is meshed with the first gear ring 38, and space is left for the second gear ring 39 to move. When the first gear ring 38 and the second gear ring 39 are meshed, the first rubber ring 36 and the second rubber ring 391 are in a mutually squeezed state.

[0035] During specific implementation, when it is necessary to drive the plate body 41 to rotate, the servo motor 61 is started, and the output shaft of the servo motor 61 drives the rotating shaft 62 to rotate through the coupling, and the rotating shaft 62 drives the first mounting ring 37 and the first ring gear 38 to rotate. Since the first ring gear 38 and the second ring gear 39 are engaged, the second ring gear 39, the third mounting ring 35, the second mounting ring 31 and the plate body 41 are driven to rotate, thereby driving the plate body 41 to rotate.

[0036] Since space is left between the first gear ring 38 and the second gear ring 39 for the second gear ring 39 to move, that is, while ensuring that the first gear ring 38 and the second gear ring 39 are engaged, the second gear ring 39 has a certain amount of movement relative to the first gear ring 38, so that during the rotation of the plate body 41, the plate body 41 has a certain amount of movement, so that the plate body 41 can rotate in contact with the inner wall of the rotating groove 8, so as to facilitate shoveling up the soybean meal on the inner wall of the bottom of the tank body 1.

[0037] By providing the first rubber ring 36 and the second rubber ring 391 and keeping them in contact at all times, the meshing of the first gear ring 38 and the second gear ring 39 is stabilized, thereby improving the rotational stability of the plate body 41 and providing the plate body 41 with a certain buffer space to improve the operational stability of the plate body 41. Furthermore, since the plate body 41 needs to rotate slowly when being driven to rotate, the transmission stability of the first gear ring 38 and the second gear ring 39 is further improved, which is convenient for practical use.

[0038] The bearings 33 are provided to facilitate supporting the two mounting rings and improve their rotational stability.

[0039] The blocking assembly 32 includes: The first retaining ring 321 is fixedly sleeved on the inner wall of one side of the second mounting ring 31 located inside the tank body 1; The second retaining ring 323 is fixedly mounted on the side wall of the rotating shaft 62 . A rubber ring 322 is fixedly mounted between the inner wall of the first retaining ring 321 and the outer wall of the second retaining ring 323 to seal the second mounting ring 31 and the rotating shaft 62 .

[0040] In a specific implementation, the rubber ring 322 is used to seal the space between the second mounting ring 31 and the rotating shaft 62 to prevent soybean meal and the like from entering the meshing position of the first gear ring 38 and the second gear ring 39, thereby avoiding affecting the stability of the meshing of the first gear ring 38 and the second gear ring 39. The rubber ring 322 has a certain elasticity, that is, it does not affect the movement of the plate body 41.

[0041] The inner wall of the tank body 1 is provided with a mounting groove for mounting the mounting sleeve 34; The rotating shaft 62 is hollow so that the air guide tube 47 can extend along the inner wall of the rotating shaft 62 into the plate body 41, making it easier to install the air guide tube 47; Among them, the plate body 41 is fixedly provided with or opened with a conduit or air guide groove connecting the air guide pipe 47 with multiple nozzles 43, so that the gas transported by the air guide pipe 47 can enter the spray group and be sprayed out by the nozzle 43. This is the existing technology and will not be elaborated here.

[0042] Example 2: Please refer to Figure 14 and Figure 15 The difference between this embodiment and the first embodiment is that the limiting mechanism 7 includes: The casing 71 is fixed to the top inner wall of the tank body 1, and a guide hole 75 is opened at the bottom of the casing 71. The bottom inner wall of the casing 71 is designed to be curved, and the curvature of the bottom inner wall of the casing 71 gradually increases from away from the guide hole 75 to close to the guide hole 75; The tube body 72 is fixed on the top of the tank body 1 and extends into the casing 71. A filter cartridge 73 is fixedly provided at one end of the tube body 72 located in the casing 71. A baffle 74 is fixedly provided at the bottom of the filter cartridge 73. The side wall diameter of the baffle 74 is larger than the inner wall diameter of the guide hole 75 and the outer wall diameter of the filter cartridge 73, and a gap is left between the bottom of the baffle 74 and the bottom inner wall of the casing 71.

[0043] During specific implementation, the gas in the tank body 1 enters the casing 71 along the guide hole 75 and is filtered by the filter cartridge 73, which blocks the discharge of oxygen while allowing carbon dioxide to pass through, thereby reducing the total amount of gas in the tank body 1 while retaining oxygen in the tank body 1, so as to maintain the oxygen concentration required for soybean meal fermentation in the tank body 1, making it convenient for fermentation.

[0044] Filter cartridge 73 uses gas separation membrane technology to separate carbon dioxide and oxygen. The molecular diameter of carbon dioxide is approximately 0.33 nm, and the molecular diameter of oxygen is approximately 0.346 nm. Selective permeation can be achieved by regulating the membrane pore size. For example, polyimide (PI) or polymeric immobilized microporous (PIM) membranes can achieve separation based on molecular size differences.

[0045] By providing a baffle 74 and making the side wall diameter of the baffle 74 larger than the inner wall diameter of the guide hole 75 and the outer wall diameter of the filter cartridge 73, a gap is left between the bottom of the baffle 74 and the bottom inner wall of the casing 71, thereby blocking the bacterial liquid and the like from entering the casing 71, and facilitating the entry of gas into the casing 71 along the gap, thereby facilitating the filtration of gas and blocking the bacterial liquid and the like from contacting the filter cartridge 73, thereby preventing soybean meal and the like in the bacterial liquid from clogging the filter cartridge 73 and affecting the filtration use. By making the bottom inner wall of the casing 71 curved, a small amount of bacterial liquid entering the casing 71 can be easily discharged to the outside of the casing 71.

[0046] Example 3: Please refer to Figure 11 、 Figure 12 and Figure 13 The difference between this embodiment and the second embodiment is that the scraping mechanism 2 includes: The arc-shaped plate 21 is arranged in a lifting manner in the tank body 1. Ear plates 22 are fixed on both sides of the top of the arc-shaped plate 21. The bottom of the ear plates 22 is fixed with a movable sleeve 24. A scraper ring 23 is fixed on the inner side of the bottom of the movable sleeve 24, and the outer wall of the scraper ring 23 is in contact with the inner wall of the tank body 1. The movable groove 26 is opened on both sides of the inner wall of the tank body 1. The top inner wall and the bottom inner wall of the movable groove 26 are fixed with a rod body 25. The side wall of the rod body 25 is sleeved on the inner wall of the movable sleeve 24, and a through hole for sleeved with the rod body 25 is opened on the top of the ear plate 22. The side wall of the rod body 25 and the top of the ear plate 22 are sleeved with a spring so that the scraper ring 23 has a tendency to move downward.

[0047] A support plate 5 is fixed to the middle end of the side wall of the rotating shaft 62. The support plate 5 is located on the inner side of the plate body 41 and is designed to be inclined so that the support plate 5 contacts the arc plate 21 before the plate body 41. In this way, in the process of the support plate 5 and the plate body 41 successively contacting and pressing the arc plate 21, the scraper ring 23 moves upward.

[0048] In the specific implementation, when the rotating shaft 62 drives the plate body 41 to rotate, the rotating shaft 62 drives the resisting plate 5 to rotate synchronously, and since the resisting plate 5 is designed to be inclined, the resisting plate 5 is in contact with the arc-shaped plate 21 before the plate body 41, so that the arc-shaped plate 21 is moved upward by the extrusion of the resisting plate 5, the ear plate 22, the moving sleeve 24 and the scraping ring 23 are driven to move, so that the scraping ring 23 scrapes the soybean meal attached to the inner side wall of the tank body 1, so that the soybean meal falls into the fungus liquid, reduces the amount of soybean meal attached to the inner side wall of the tank body 1, avoids that the uneven distribution of the materials in the tank body 1 caused by too much soybean meal attached to the inner wall of the tank body 1 affects the uniformity of fermentation, and the materials attached to the tank body 1 may affect the temperature in the fermentation process, thereby affecting the fermentation effect, and the materials attached to the tank body 1 are easy to breed bacteria and mold, which causes hygiene problems, when the plate body 41 rotates to the position away from the arc-shaped plate 21, the arc-shaped plate 21 is moved downward under the action of the spring, so as to drive the scraping ring 23 to move downward, thereby repeatedly scraping the inner side wall of the tank body 1.

[0049] By extruding the arc-shaped plate 21 by the resisting plate 5 and the plate body 41 in turn, the arc-shaped plate 21 is moved upward against the elasticity of the spring, thereby scraping the inner side wall of the tank body 1, avoiding that the plate body 41 is hindered in movement with the scraping ring 23 in the rotating process, and when the resisting plate 5 and the plate body 41 are alternately in contact with the arc-shaped plate 21, the arc-shaped plate 21 is moved downward under the action of the spring, thereby knocking the plate body 41 to make the plate body 41 shake, so as to facilitate the soybean meal inside the plate body 41 to fall off; By arranging the sleeve shell 71 on the inner wall top of the tank body 1 and in the inner recess of the arc-shaped plate 21, the sleeve shell 71 is not conflicted with the arc-shaped plate 21 due to the rising of the arc-shaped plate 21, thereby facilitating the actual use. By arranging the rod body 25, the moving sleeve 24 is limited, thereby limiting the lifting of the arc-shaped plate 21 and the scraping ring 23.

[0050] The tank body 1 of the present application is usually provided with an oxygen concentration sensor, a temperature sensor and a pressure relief valve, etc., so as to be used in the process of soybean meal fermentation, which is prior art and not shown in the figure, and will not be described here.

[0051] The present application also provides a production method of the fermentation soybean meal production equipment, which adopts the fermentation soybean meal production equipment, and the method comprises the following steps: S1: The auxiliary mechanism 4 is driven to rotate by the driving mechanism 6, thereby turning up the soybean meal accumulated on the inner wall bottom of the tank body 1, with the continuous rotation of the auxiliary mechanism 4, the plate body 41 is turned over along the rotating shaft 62, in this process, the soybean meal is continuously dropped out from the inner side of the plate body 41, thereby making the soybean meal contact with the fungus liquid to assist the fermentation of the soybean meal, in the process of the rotation of the plate body 41, the plate body 41 cooperates with the resisting plate 5 to drive the scraping mechanism 2 to lift, thereby scraping the inner side wall of the tank body 1 by the scraping ring 23 to reduce the amount of soybean meal attached to the inner side wall of the tank body 1. S2: During the rotation of the auxiliary mechanism 4, oxygen is transported into the plate 41 and discharged along the nozzle 43, so that the oxygen contacts the soybean meal and the bacterial liquid, further assisting the fermentation of the soybean meal. Since the soybean meal produces a gas mainly composed of carbon dioxide during the fermentation process, as the gas in the tank body 1 increases, in order to ensure the stability of the tank body 1, the carbon dioxide gas is discharged through the limiting mechanism 7 and the oxygen is blocked, thereby ensuring that the air pressure in the tank body 1 is at a normal state while ensuring the oxygen content in the tank body 1, thereby assisting the fermentation of the soybean meal.
