Abstract
Description
Technical Field
[0001] This application relates to the field of feed fermentation technology, and in particular to a fermentation device that facilitates the full fermentation of feed ingredients. Background Technology
[0002] Feed ingredient fermentation refers to the process by which complex components in feed ingredients, such as starch, protein, and cellulose, are transformed into nutrients that are easily digested and absorbed by animals through the fermentation action of microorganisms. Commonly used microorganisms in the fermentation process include lactic acid bacteria, yeast, and Bacillus.
[0003] Feed fermentation includes aerobic fermentation and anaerobic fermentation. In existing feed fermentation processes, in order to ensure that the feed fermentation is complete, a combination of aerobic and anaerobic fermentation is used to make the feed fermentation more complete.
[0004] In related technologies, large-scale feed fermentation equipment typically achieves sealing by simply covering it with a plastic film during anaerobic fermentation. This method has poor sealing performance and may cause the odor produced during fermentation to leak out, which could have a certain impact on the health of the staff involved.
[0005] Therefore, it is necessary to propose a fermentation device that facilitates the full fermentation of feed ingredients, and to improve the sealing performance of the fermentation equipment. This has become an important technical problem that urgently needs to be solved. Utility Model Content
[0006] This application provides a fermentation device that facilitates the full fermentation of feed ingredients, aiming to solve the problem that in the prior art, large-scale feed fermentation equipment generally only achieves sealing by covering with a plastic film during anaerobic fermentation, which has poor sealing performance and may cause the leakage of odor generated during fermentation, thus having a certain impact on the health of relevant personnel.
[0007] To achieve the above objectives, this application proposes a fermentation device that facilitates the full fermentation of feed ingredients, comprising: a fermentation tank; a feed inlet disposed on the fermentation tank; a steam pipe disposed at the bottom of the fermentation tank; an air inlet pipe disposed at the bottom of the fermentation tank; a fermentation agent pipe disposed on the fermentation tank; and a ring pipe connected to the fermentation agent pipe, the ring pipe being located inside the fermentation tank, with a plurality of spray nozzles spaced apart at the bottom end of the ring pipe.
[0008] In some embodiments, the system further includes: a thermometer extending into the interior of the fermenter; a cooling pipe disposed within the fermenter; a cooling water inlet disposed on the fermenter and connected to the cooling pipe; and a cooling water outlet disposed on the fermenter and connected to the cooling pipe.
[0009] In some embodiments, the device further includes: a stirring drive installed in the fermenter; a stirring shaft rotatably disposed in the fermenter, with a portion of the stirring shaft located inside the fermenter; and a plurality of stirring blades disposed on the outer circumferential surface of the stirring shaft.
[0010] In some embodiments, the device further includes: a plurality of helical blades, which are spaced apart on the outer peripheral surface of the stirring shaft.
[0011] In some embodiments, the fermenter further includes: a sampling port disposed at the bottom of the fermenter; a sight glass disposed at the top of the fermenter; and a rinsing port disposed at the top of the fermenter.
[0012] In some embodiments, the fermenter further includes: a manhole disposed at the top of the fermenter; and a ladder disposed on the inner wall of the fermenter.
[0013] This application proposes a fermentation device that facilitates the full fermentation of feed ingredients, comprising: a fermentation tank; a feed inlet located on the fermentation tank; a steam pipe located at the bottom of the fermentation tank; an air inlet pipe located at the bottom of the fermentation tank; a fermentation agent pipe located on the fermentation tank; and a ring pipe connected to the fermentation agent pipe, located inside the fermentation tank, with several spray nozzles spaced apart at the bottom end of the ring pipe. Feed ingredients are fed into the fermentation tank through the feed inlet. After high-temperature sterilization via the steam pipe, air is introduced into the fermentation tank through the air inlet pipe, and corresponding aerobic bacteria are sprayed through the fermentation agent pipe and the ring pipe for aerobic fermentation. Then, inert gas is introduced into the fermentation tank through the air inlet pipe to expel the air, and corresponding anaerobic fermentation bacteria are sprayed through the fermentation agent pipe and the ring pipe for anaerobic fermentation. This combined aerobic and anaerobic fermentation process facilitates more complete fermentation of the feed ingredients. Spraying the corresponding fermentation agent through the fermentation agent pipe and the ring pipe is beneficial to the full mixing of the fermentation agent and the feed raw materials, which improves the fermentation of the feed raw materials. The entire fermentation process is carried out in the fermentation tank, which has strong sealing and the gas produced during fermentation is not easy to leak. Attached Figure Description

[0023] See Figure 1As shown, this application proposes a fermentation device that facilitates the full fermentation of feed ingredients, comprising: a fermentation tank 21; a feed inlet 11 disposed on the fermentation tank 21; a steam pipe 22 disposed at the bottom of the fermentation tank 21; an air inlet pipe 2 disposed at the bottom of the fermentation tank 21; a fermentation agent pipe 10 disposed on the fermentation tank 21; and a ring pipe 17 connected to the fermentation agent pipe 10, the ring pipe 17 being located inside the fermentation tank 21, with a plurality of spray nozzles 18 spaced apart at the bottom end of the ring pipe 17.
[0024] The fermentation tank 21 is the structural basis of a fermentation device that facilitates the full fermentation of feed ingredients. Other structures on the fermentation device that facilitates the full fermentation of feed ingredients are directly or indirectly connected to the fermentation tank 21. The fermentation tank 21 includes a lower end cap, a middle cylinder, and an upper end cap. The lower end cap is connected to a frame 1. The fermentation tank 21 is placed on the ground through the frame 1. In this embodiment, the internal volume of the fermentation tank 21 is approximately 50 cubic meters.
[0025] Among them, the steam pipe 22 is used to introduce high-temperature steam into the fermentation tank 21 for steam sterilization, and the air inlet pipe 2 is used to introduce inert gas or air into the fermentation tank 21. Air is introduced into the fermentation tank 21 through the air inlet pipe 2 for aerobic fermentation, and then inert gas is introduced into the fermentation tank through the air inlet pipe 2 to exhaust the air in the fermentation tank 21 for anaerobic fermentation. Through the fermentation process that combines anaerobic and aerobic fermentation, the feed raw materials are fully fermented.
[0026] In this embodiment, an exhaust port 13 is provided at the top of the fermenter 21 to discharge the gas inside the fermenter 21 and prevent excessive pressure inside the fermenter 21. The gas discharged through the exhaust port 13 needs to be treated before being discharged. A first support member is provided inside the fermenter 21 to fix the steam pipe 22 and the air inlet pipe 2. One end of the first support member is connected to the inner wall of the fermenter 21, and the other end of the first support member is connected to the steam pipe 22 or the air inlet pipe 2. An oxygen sensor 25 is provided at the top of the fermenter 21 to monitor the oxygen concentration in the fermenter 21.
[0027] The fermentation agent tube 10 and the ring tube 17 are used to spray the corresponding fermentation auxiliary materials, such as lactic acid bacteria, yeast and Bacillus. The corresponding bacterial solution flows from the fermentation agent tube 10 into the ring tube 17 and is sprayed onto the feed raw materials from several spray nozzles 18 at the bottom of the ring tube 17.
[0028] In this embodiment, a second support member for fixing the ring pipe 17 is also provided in the fermenter 21. One end of the second support member is connected to the ring pipe 17, and the other end of the second support member is connected to the ring pipe 17. Multiple second support members can be provided, and multiple second support members are arranged at intervals along the circumference of the ring pipe 17.
[0029] Specifically, feed ingredients are placed into the fermentation tank 21 through the feed inlet 11. After high-temperature sterilization via the steam pipe 22, air is introduced into the fermentation tank through the air inlet pipe 2, and corresponding aerobic bacteria are sprayed through the fermentation agent pipe 10 and the ring pipe 17 for aerobic fermentation. Then, inert gas is introduced into the fermentation tank through the air inlet pipe 2 to expel the air from the fermentation tank 21, and corresponding anaerobic fermentation agents are sprayed through the fermentation agent pipe 10 and the ring pipe 17 for anaerobic fermentation. This combined aerobic and anaerobic fermentation process helps to ensure more complete fermentation of the feed ingredients. Spraying the corresponding fermentation agents through the fermentation agent pipe 10 and the ring pipe 17 facilitates thorough mixing of the fermentation agents and feed ingredients, improving the completeness of fermentation. The entire fermentation process is carried out within the fermentation tank 21, which has strong sealing properties, making it difficult for the gases produced during fermentation to leak.
[0030] See Figure 1 and Figure 3 As shown, in some embodiments, the system further includes: a thermometer 24, which extends into the fermentation tank 21 and is used to measure the temperature of the feed inside the fermentation tank 21, preferably greater than 25°C and less than 35°C; a cooling pipe 3, which is disposed inside the fermentation tank 21 and is used to control the temperature of the feed raw materials inside the fermentation tank 21. Since heat is generated during fermentation, the cooling water in the cooling pipe 3 can remove the heat from the feed raw materials, maintaining the temperature of the feed raw materials within the range of 25°C-35°C; a cooling water inlet 8, which is disposed on the fermentation tank 21 and connected to the cooling pipe 3, with cooling water flowing into the cooling pipe 3 from the cooling water inlet 8; and a cooling water outlet 9, which is disposed on the fermentation tank 21 and connected to the cooling pipe 3. After removing the heat from the feed raw materials, the cooling water flows out from the cooling water outlet 9.
[0031] In this embodiment, the fermenter 21 also includes a third support 7 for fixing the cooling pipe 3. The third support 7 is connected to the inner wall of the fermenter 21 and to the cooling pipe 3, and is used to fix the cooling pipe 3 to the inner wall of the fermenter 21. The cooling water inlet 8 is connected to a pump, a cooling water pool and other structures. The cooling water discharged from the cooling water outlet 9 flows back into the cooling water pool after being cooled.
[0032] See Figure 1As shown, in some embodiments, the system further includes: a stirring drive 12, which is mounted on the fermentation tank 21; the stirring drive 12 is a motor, and the fermentation tank 21 is provided with a mounting platform for mounting the stirring drive 12. The stirring drive 12 has an output end, which is connected to a first pulley shaft via a coupling. A first pulley is provided on the first pulley shaft. A stirring shaft 19 is rotatably mounted on the fermentation tank 21, with a portion of the stirring shaft 19 located inside the fermentation tank 21. A second pulley 15 is provided at the end of the stirring shaft 19, and a transmission belt is provided on the first pulley and the second pulley 15. A plurality of stirring blades 6 are disposed on the outer circumferential surface of the stirring shaft 19. The stirring drive 12 drives the stirring shaft 19 to rotate, thereby driving the stirring blades 6 to rotate, ensuring sufficient fermentation.
[0033] In this embodiment, since the stirring shaft 19 is relatively long, an intermediate bearing 4 is provided inside the fermentation tank 21. The stirring shaft 19 is rotatably connected to the intermediate bearing 4, and the intermediate bearing 4 is connected to the inner wall of the fermentation tank 21 through a mounting bracket.
[0034] See Figure 1 As shown, in some embodiments, it further includes: a plurality of helical blades 5, which are spaced apart on the outer peripheral surface of the stirring shaft 19. The helical blades 5 facilitate vertical stirring of the feed ingredients, allowing the feed ingredients to ferment more fully.
[0035] See Figure 1 and Figure 2 As shown, in some embodiments, the fermentation tank 21 further includes: a sampling port 23, located at the bottom of the fermentation tank 21, used to collect a portion of the feed ingredients as a sample to predict the overall fermentation process of the feed ingredients; a sight glass 26, located at the top of the fermentation tank 21, used to observe the interior of the fermentation tank 21; and a rinsing port 14, also located at the top of the fermentation tank 21. The rinsing port 14 can be connected to a rinsing water source, facilitating rinsing of the entire fermentation tank 21 after fermentation.
[0036] See Figure 1 As shown, in some embodiments, the fermenter further includes: a manhole 16 disposed at the top of the fermenter 21; and a ladder 20 disposed on the inner wall of the fermenter 21. The manhole 16 allows personnel to enter the interior of the fermenter 21 for maintenance, and the ladder 20 allows maintenance workers to move vertically within the fermenter 21.
