Description

Technical Field

[0001] This invention relates to the field of feed fermentation production technology, and in particular to a fermented feed production equipment and method. Background Technology

[0002] Fermented feed production equipment is a key piece of equipment for achieving efficient and environmentally friendly feed production in modern animal husbandry. It integrates core functions such as raw material pretreatment, precise ingredient proportioning, automated mixing, efficient fermentation, and drying and packaging. By scientifically controlling fermentation conditions such as temperature, humidity, and oxygen content, it promotes the rapid reproduction of beneficial microorganisms, transforming ordinary raw materials into high-quality fermented feed rich in probiotics, enzymes, and active substances. The equipment adopts an intelligent control system to ensure a stable and reliable production process, significantly improving the nutritional value and digestibility of feed, while reducing antibiotic use and improving animal health. Its modular design allows for flexible adjustment according to production scale, making it suitable for various farms and feed processing enterprises. It is an important tool for promoting the green and sustainable development of animal husbandry and improving breeding efficiency.

[0003] However, in actual use, the existing equipment is prone to forming a sedimentation dead zone at the bottom of the tank in the traditional fermentation tank design, resulting in excessively high local material concentration and insufficient fermentation. Furthermore, the overall stirring system is not optimized for gas-liquid mixing, which makes it easy for the air introduced into the tank to form large bubbles that quickly gather, float, and escape, resulting in low dissolved oxygen efficiency. Therefore, a fermented feed production equipment and method are proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of materials to form sedimentation dead zones at the bottom of the tank, resulting in excessively high local material concentrations and insufficient fermentation, and the insufficient optimization of gas-liquid mixing by the mixing system, which causes air introduced into the tank to easily form large bubbles that quickly gather, float, and escape, resulting in low dissolved oxygen efficiency. Therefore, this invention proposes a fermented feed production equipment and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fermented feed production device includes a fermentation tank. A liquid inlet and a feed inlet are fixedly connected to the upper part of the fermentation tank. A dispersing mechanism is provided at the bottom of the feed inlet. A temperature control mechanism is provided outside the fermentation tank. A control mechanism is provided at the top of the fermentation tank. The control mechanism drives a first rotating rod and a second rotating rod at the bottom to rotate. A turbine is fixedly connected to the bottom of the second rotating rod, and the turbine is rotatably connected to the bottom of the fermentation tank. A first bevel gear is fixedly connected to the lower part of the first rotating rod. Second bevel gears are meshed on both sides of the first bevel gear. A first eccentric shaft is fixedly connected to the second bevel gear. A first connecting plate is rotatably connected to the first eccentric shaft. A connecting rod is rotatably connected to the first connecting plate. An annular plate is fixedly connected to the bottom of the connecting rod.

[0006] During fermentation, a control mechanism drives the first and second rotating rods to rotate. The rotation of the second rotating rod drives the turbine to rotate, which generates strong shear force and axial flow, suspending the bottom sediment and mixing it thoroughly with the upper bacterial solution. At the same time, the rotation of the turbine drives the first rotating rod to rotate, which in turn drives the connecting rod to reciprocate. This, in turn, causes the annular plate to move up and down, disturbing the liquid surface and preventing large bubbles from escaping. Simultaneously, it presses the surface foam into the liquid phase, further utilizing the oxygen in the foam. One side of the annular plate is in contact with the inner wall of the fermenter, and it can simultaneously scrape the inner wall during its up and down movement.

[0007] The above technical solution further includes: The second bevel gear is rotatably connected to the reciprocating housing, which is fixedly connected to the lower part of the top cover.

[0008] A limiting sleeve is fixedly connected inside the reciprocating housing, and the limiting sleeve is slidably connected to the connecting rod.

[0009] The control mechanism includes a control housing fixedly connected to the top of the fermenter, a first motor is installed inside the control housing, and a control component is installed at the output end of the first motor.

[0010] The control component includes a third bevel gear located at the output end of a first motor, a fourth bevel gear meshing with the third bevel gear, a fifth bevel gear meshing with the fourth bevel gear, a first rotating rod fixedly connected to the fifth bevel gear, and the first rotating rod being rotatably connected to the control housing. The third, fourth, and fifth bevel gears have the same module and the same number of teeth.

[0011] The third bevel gear is fixedly connected to the second rotating rod, and the second rotating rod is rotatably connected to the first rotating rod.

[0012] The spreading mechanism includes a spreading housing fixedly connected to the bottom of the feeding port, a second motor is provided on the upper part of the spreading housing, and a spreading component is provided at the output end of the second motor.

[0013] The dispersing assembly includes a second eccentric shaft located at the output end of a second motor, a second connecting plate rotatably connected to the second eccentric shaft, a sliding connection between the second connecting plate and a swing plate, and a dispersing disc fixedly connected to the upper part of the swing plate.

[0014] The temperature control mechanism includes a temperature control chamber fixedly connected to the outside of the fermentation tank, a conduit provided at the upper part of the temperature control chamber, a thermometer inserted inside the temperature control chamber, and two conduits respectively located on the upper and lower sides of the temperature control chamber.

[0015] A method of using fermented feed production equipment includes the following steps: Step 1: Slowly add the liquid raw materials into the fermentation tank through the inlet, and then use the spreading mechanism to evenly spread the solid raw materials added through the inlet into the liquid raw materials in the fermentation tank; Step 2: The control mechanism drives the first and second rotating rods to rotate. The second rotating rod drives the turbine fixedly connected to its bottom to rotate. The rotation of the turbine generates strong shear force and axial flow, which suspends the material settled at the bottom of the fermenter and mixes it thoroughly with the bacterial liquid in the upper layer. Step 3: The first rotating rod drives the second bevel gear to rotate, and the rotation of the second bevel gear drives the connecting rod to reciprocate. The bottom of the connecting rod is fixedly connected to an annular plate, which drives the annular plate to move up and down, disturbing the surface of the fermentation liquid and preventing large bubbles from accumulating and escaping. Step 4: During the fermentation process, the temperature inside the fermentation tank is raised or lowered by a temperature control mechanism to ensure that the fermentation takes place under suitable temperature conditions.

[0016] The present invention has the following beneficial effects: 1. In this invention, during the fermentation process, the starting control mechanism can drive the first rotating rod and the second rotating rod to rotate synchronously. The rotation of the second rotating rod can drive the turbine fixedly connected to the bottom to rotate. The rotation of the turbine can generate radial flow, which can resuspend the sediment and prevent the formation of dead zones at the bottom of the fermentation tank. Material sedimentation affects the activity of the microbial community. At the same time as the turbine rotates, the first rotating rod drives the first bevel gear to rotate synchronously. The rotation of the first bevel gear can drive the connecting rod to move back and forth. The back and forth movement of the connecting rod can drive the annular plate to move up and down. When the annular plate is at its lowest point, it is close to the bottom of the tank, pushing the residual material into the mainstream zone and preventing the microbial autolysis caused by the depletion of material in the later stage of fermentation.

[0017] 2. In this invention, during the process of adding solid raw materials, the raw materials fall onto the surface of the spreading disc through the feeding port. By starting the second motor, the spreading disc can be driven to swing back and forth, thereby spreading the material evenly and avoiding the accumulation of material during the addition process, which would affect the uniformity of the material. During the fermentation process, the fermentation temperature can be flexibly adjusted through the temperature control mechanism. Attached Figure Description

[0020] 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.

[0021] Example 1 like Figures 1-6 As shown, the present invention proposes a fermented feed production equipment, including a fermentation tank 1. The upper part of the fermentation tank 1 is fixedly connected to a liquid inlet 7 and a feed inlet 8. A dispersing mechanism is provided at the bottom of the feed inlet 8. A temperature control mechanism is provided on the outside of the fermentation tank 1. A control mechanism is provided on the top of the fermentation tank 1. The control mechanism drives the first rotating rod 14 and the second rotating rod 21 at the bottom to rotate. A turbine 9 is fixedly connected to the bottom of the second rotating rod 21. The turbine 9 is rotatably connected to the bottom of the fermentation tank 1. A first bevel gear 15 is fixedly connected to the lower part of the first rotating rod 14. A second bevel gear 16 is meshed on both sides of the first bevel gear 15. A first eccentric shaft 23 is fixedly connected to the second bevel gear 16. A first connecting plate 24 is rotatably connected to the first eccentric shaft 23. A connecting rod 11 is rotatably connected to the first connecting plate 24. An annular plate 10 is fixedly connected to the bottom of the connecting rod 11.

[0022] During fermentation, the control mechanism drives the first rotating rod 14 and the second rotating rod 21 to rotate. The rotation of the second rotating rod 21 drives the turbine 9 to rotate. The rotation of the turbine 9 generates strong shear force and axial flow, which suspends the bottom sediment and mixes it thoroughly with the upper bacterial liquid. At the same time, the rotation of the turbine 9 drives the first rotating rod 14 to rotate, which drives the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 drives the connecting rod 11 to reciprocate, which in turn drives the annular plate 10 to move up and down to disturb the liquid surface, preventing large bubbles from accumulating and escaping. At the same time, it presses the surface foam into the liquid phase, further utilizing the oxygen in the foam. One side of the annular plate 10 is attached to the inner wall of the fermenter 1, and it can scrape the inner wall synchronously during the up and down movement.

[0023] The second bevel gear 16 is rotatably connected to the reciprocating housing 12, which is fixedly connected to the lower part of the top cover 2. A limiting sleeve 22 is fixedly connected inside the reciprocating housing 12, and the limiting sleeve 22 is slidably connected to the connecting rod 11. The control mechanism includes a control housing 6 fixedly connected to the top of the fermenter 1. A first motor 17 is installed inside the control housing 6. A control component is installed at the output end of the first motor 17. The control component includes a third bevel gear 18 installed at the output end of the first motor 17. The third bevel gear 18 is meshed with a fourth bevel gear 19, and the fourth bevel gear 19 is meshed with a fifth bevel gear 20. The fifth bevel gear 20 is fixedly connected to a first rotating rod 14, which is rotatably connected to the control housing 6. The third bevel gear 18, the fourth bevel gear 19, and the fifth bevel gear 20 have the same module and the same number of teeth. The third bevel gear 18 is fixedly connected to a second rotating rod 21, which is rotatably connected to the first rotating rod 14.

[0024] In this embodiment, during the fermentation process, starting the first motor 17 can drive the third bevel gear 18 to rotate. The rotation of the third bevel gear 18 drives the fourth bevel gear 19 and the second rotating rod 21 to rotate synchronously. The rotation of the fourth bevel gear 19 can drive the meshing fifth bevel gear 20 to rotate. The rotation of the fifth bevel gear 20 drives the fixedly connected first rotating rod 14 to rotate, thereby realizing the synchronous rotation of the first rotating rod 14 and the second rotating rod 21.

[0025] The rotation of the second rotating rod 21 can drive the turbine 9 fixedly connected to the bottom to rotate. The turbine 9 generates strong shear force and axial flow, which suspends the bottom sediment and mixes it thoroughly with the upper bacterial liquid, improving the uniformity of fermentation and preventing the formation of dead zones at the bottom of the fermenter 1. Material deposition affects the activity of the bacterial community. Moreover, when the turbine 9 rotates, it breaks the air bubbles into tiny bubbles, increasing the gas-liquid contact area and improving the dissolved oxygen coefficient, thus meeting the oxygen requirements of aerobic bacteria.

[0026] While the turbine 9 rotates, the first rotating rod 14 synchronously drives the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 drives the meshing second bevel gear 16 to rotate. The rotation of the second bevel gear 16 drives the fixedly connected first eccentric shaft 23 to rotate. The rotation of the first eccentric shaft 23 drives the rotatingly connected first connecting plate 24 to rotate, which in turn drives the rotatingly connected connecting rod 11 to move back and forth. The slidingly connected limiting sleeve 22 can also ensure the stability of the connecting rod 11 during movement. The reciprocating movement of the connecting rod 11 can drive the fixedly connected annular plate 10 to move up and down. When the annular plate 10 is at its lowest point, it is close to the bottom of the tank, pushing the residual material into the mainstream area to avoid the autolysis of the cells due to the depletion of material in the later stage of fermentation. Moreover, the annular plate 10 moves up and down close to the inner wall of the fermentation tank 1 to scrape off the material attached to the wall surface, preventing the protein, polysaccharide and other components in the fermentation liquid from easily depositing on the wall surface, forming a biofilm, and hindering heat and mass transfer.

[0027] Example 2 like Figures 1-6 As shown, the spreading mechanism includes a spreading housing 13 fixedly connected to the bottom of the feeding port 8, a second motor 25 is provided on the upper part of the spreading housing 13, a spreading component is provided at the output end of the second motor 25, the spreading component includes a second eccentric shaft 26 provided at the output end of the second motor 25, a second connecting plate 27 is rotatably connected to the second eccentric shaft 26, the second connecting plate 27 is slidably connected to the swing plate 28, and a spreading disc 29 is fixedly connected to the upper part of the swing plate 28.

[0028] The temperature control mechanism includes a temperature control chamber 3 fixedly connected to the outside of the fermentation tank 1, a conduit 4 on the upper part of the temperature control chamber 3, a thermometer 5 inserted inside the temperature control chamber 3, and two conduits 4 respectively located on the upper and lower sides of the temperature control chamber 3.

[0029] In this embodiment, materials can be fed into the fermentation tank 1 through the liquid inlet 7 and the feed inlet 8 located at the top of the fermentation tank 1. During the addition of solid raw materials, the raw materials fall onto the surface of the spreading plate 29 through the feed inlet 8. By starting the second motor 25, the second eccentric shaft 26 can be driven to rotate. The rotation of the second eccentric shaft 26 drives the rotatingly connected second connecting plate 27 to rotate. The rotation of the second connecting plate 27 can prevent the slidingly connected swing plate 28 from rotating, thereby driving the fixedly connected spreading plate 29 to swing back and forth, so as to evenly sprinkle the materials and avoid the accumulation of materials during the addition process, which would affect the uniformity of the materials. During the fermentation process, liquid can be delivered into the temperature control chamber 3 through the conduit 4, so as to flexibly adjust the fermentation temperature. Moreover, the thermometer 5 inserted into the temperature control chamber 3 can reflect the temperature change at all times, so as to facilitate temperature control.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
