Description

Technical Field

[0001] This application relates to the field of feed fermentation technology, and in particular to a feed fermentation device with a stirring function. 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 sufficient, a combination of aerobic and anaerobic fermentation is used to make the feed fermentation more complete. However, aerobic fermentation generates a lot of heat, causing the feed temperature to rise, which leads to the feed deviating from the optimal temperature range.

[0004] In related technologies, feed fermentation equipment typically uses water cooling to cool the feed and prevent it from falling out of its optimal temperature range. However, the cooling effect of water cooling is poor for the feed in the center of the fermentation tank, resulting in incomplete fermentation of the feed in the center of the fermentation tank.

[0005] Therefore, it is necessary to propose a feed fermentation device with stirring function to effectively control the temperature of the feed inside the fermentation tank, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0006] This application provides a feed fermentation device with a stirring function, which aims to solve the problem that in the prior art, feed fermentation devices usually only use water cooling to cool the feed and prevent the feed from going out of the optimal temperature range. However, the cooling effect of water cooling is poor for the feed in the center of the fermentation tank, resulting in incomplete fermentation of the feed in the center of the fermentation tank.

[0007] To achieve the above objectives, this application proposes a feed fermentation device with a stirring function, comprising: a fermentation tank; a stirring shaft rotatably disposed on the fermentation tank; stirring blades rotatably disposed on the outer circumferential surface of the stirring shaft; a sealing cylinder disposed on the outer surface of the fermentation tank, with a cooling space provided between the sealing cylinder and the fermentation tank; and multiple annular protrusions spaced apart on the inner wall surface of the fermentation tank.

[0008] In some embodiments, the system further includes: a cooling water inlet disposed at the lower part of the sealing cylinder, the cooling water inlet communicating with the cooling space; and a cooling water outlet disposed at the upper part of the sealing cylinder, the cooling water outlet communicating with the cooling space.

[0009] In some embodiments, the system further includes: a plurality of heat dissipation protrusions disposed on the outer peripheral surface of the fermenter, the heat dissipation protrusions being located within the cooling space.

[0010] In some embodiments, the fermenter further includes: a feed inlet located at the top of the fermenter; and a discharge outlet located at the bottom of the fermenter.

[0011] In some embodiments, the system further includes: an oxygen sensor disposed at the top of the fermenter; an air ring disposed at the bottom of the fermenter and located inside the fermenter; and an air inlet disposed at the bottom of the fermenter and connected to the air ring.

[0012] In some embodiments, it also includes: Sight glass, which is installed at the top of the fermenter; The rinsing port is located at the top of the fermenter; Frame, frame connecting sleeve.

[0013] This application proposes a feed fermentation device with a stirring function, comprising: a fermentation tank; a stirring shaft rotatably mounted on the fermentation tank; stirring blades rotatably mounted on the outer circumference of the stirring shaft; a sealing cylinder mounted on the outer surface of the fermentation tank, with a cooling space between the sealing cylinder and the fermentation tank; and multiple annular protrusions spaced apart on the inner wall of the fermentation tank. Feed and related fermentation additives enter the fermentation tank for fermentation. During fermentation, cooling water passes through the cooling space, carrying away the heat generated by the feed and cooling it to maintain its temperature between 25℃ and 35℃. Furthermore, during fermentation, the stirring shaft uniformly stirs the feed, ensuring thorough fermentation while pushing the feed towards the inner wall of the tank. The annular protrusions ensure that the feed in the center of the fermentation tank also fully contacts the tank body, and the cooling water further cools the feed in the center of the fermentation tank, ensuring thorough fermentation.

[0020] See Figure 1 , Figure 3 and Figure 4As shown, this application proposes a feed fermentation device with a stirring function, including: a fermentation tank; a stirring shaft 5, which is rotatably disposed on the fermentation tank; stirring blades 17, which are rotatably disposed on the outer circumferential surface of the stirring shaft 5; a sealing cylinder 13, which is disposed on the outer surface of the fermentation tank, and a cooling space is provided between the sealing cylinder 13 and the fermentation tank; and a plurality of annular protrusions 20, which are spaced apart on the inner wall surface of the fermentation tank.

[0021] The fermentation tank is the structural basis of a feed fermentation device with a stirring function. Other structures on the feed fermentation device with a stirring function are directly or indirectly connected to the fermentation tank. The fermentation tank includes a lower tank body 1 and an upper can 2. Both the tank body 1 and the can 2 are provided with matching connection ends. The connection ends are provided with connection holes. The two connection ends are connected together by bolts 16 and locking nuts 15. Preferably, a sealing element is provided between the two connection ends to ensure the overall sealing effect of the fermentation tank.

[0022] The stirring shaft 5 is rotatably mounted on the can 2 of the fermentation tank via bearings. A seal is also provided between the stirring shaft 5 and the can 2. The stirring shaft 5 is connected to an external drive, such as a motor. The motor drives the stirring shaft 5 to rotate, thereby driving the stirring blades 17 to rotate and stir the feed inside the fermentation tank. While ensuring sufficient fermentation, the feed is pushed as far as possible towards the inner wall of the tank 1.

[0023] The sealing cylinder 13 is installed on the tank body 1. The sealing cylinder 13 is used to form a cooling space. Cooling water passes through the cooling space, thereby removing the heat generated by the feed and cooling the feed so that the temperature of the feed is maintained between 25℃ and 35℃. The temperature of the cooling water that just enters the cooling space is between 25℃ and 28℃.

[0024] Among them, the multiple annular protrusions 20 are the core components of this application. By setting the annular protrusions 20, the feed in the center of the fermentation tank can also fully contact the fermentation tank body 1, and the feed in the center of the fermentation tank is cooled by cooling water to the tank body 1, so as to ensure that the feed is fully fermented.

[0025] Specifically, the feed and related fermentation additives are placed in the fermentation tank for fermentation. During fermentation, cooling water flows through the cooling space to remove the heat generated by the feed, cooling the feed and maintaining its temperature between 25℃ and 35℃. Furthermore, during fermentation, the stirring shaft 5 stirs the feed at a uniform speed, ensuring thorough fermentation while pushing the feed towards the inner wall of the tank 1. The annular protrusion 20 ensures that the feed in the center of the fermentation tank also makes full contact with the tank body 1, and the cooling water further cools the feed in the center of the fermentation tank, ensuring complete fermentation.

[0026] Preferably, an exhaust port is provided on the side of the tank 1 to discharge the gas produced during fermentation and to prevent excessive pressure inside the tank 1.

[0027] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the system further includes: a cooling water inlet 12, located at the lower part of the sealed cylinder 13, which connects to the cooling space, through which cooling water flows into the cooling space; and a cooling water outlet 8, located at the upper part of the sealed cylinder 13, which also connects to the cooling space. Cooling water flows out of the cooling space from the cooling water outlet 8. The cooling water inlet 12, being located below the cooling water outlet 8, helps to reduce the flow rate of the cooling water and ensures sufficient contact between the cooling water and the tank 1. The cooling water inlet 12 connects to structures such as a pump and a cooling water pool. The cooling water discharged from the cooling water outlet 8 flows back into the cooling water pool after cooling.

[0028] See Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the system further includes a plurality of heat dissipation protrusions 19 disposed on the outer peripheral surface of the fermenter and located within the cooling space. The plurality of heat dissipation protrusions 19 help to increase the contact area between the outer wall of the fermenter body 1 and the cooling water, thereby enhancing cooling efficiency.

[0029] In this embodiment, the heat dissipation protrusions 19 on the upper side of the tank 1 have a higher density, while the heat dissipation protrusions 19 on the lower side of the tank 1 have a lower density. Since the temperature of the cooling water on the upper side of the tank 1 is already high due to heat absorption, in order to ensure the cooling effect on the upper side of the tank 1, high-density heat dissipation protrusions 19 are provided on the upper side of the tank 1. On the lower side of the tank 1, the temperature of the cooling water is lower, so the density of the heat dissipation protrusions 19 is also lower.

[0030] Preferably, the sealing cylinder 13 is also provided with a thermometer hole 18, which extends into the interior of the tank 1. The temperature sensor installed on the thermometer hole 18 is used to monitor the temperature of the feed inside the tank 1. When the feed temperature increases abnormally, the flow rate of cooling water can be accelerated.

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the fermentation tank further includes: a feed inlet 3, located at the top of the fermentation tank; and a discharge outlet 10, located at the bottom of the fermentation tank. The feed inlet 3 is used to add feed and related auxiliary materials, and the discharge outlet 10 is used to discharge the fermented feed.

[0032] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the system further includes: an oxygen sensor 6, which is disposed at the top of the fermenter and on the can 2; the oxygen sensor 6 is used to monitor the oxygen concentration inside the fermenter, allowing for aerobic fermentation followed by anaerobic fermentation after the feed and related auxiliary materials are introduced. An air ring 14 is disposed at the bottom of the fermenter and located inside the fermenter, with multiple spaced air outlets on the air ring 14; an air inlet 11 is disposed at the bottom of the fermenter and connected to the air ring 14. Related auxiliary materials are added, and inert gas is introduced into the fermenter through the air inlet 11 and the air ring 14 for anaerobic fermentation. Then, air is introduced into the fermenter through the air inlet 11 and the air ring 14, and corresponding auxiliary materials are added for aerobic fermentation. The air inlet 11 is connected to an air filter, compressor, and other structures.

[0033] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the system further includes: a sight glass 4, which is disposed at the top of the fermenter; the sight glass 4 is mounted on the tank 2 and is used to observe the fermentation process inside the fermenter. A rinsing port 7, which is disposed at the top of the fermenter; the tank 1 can be rinsed through the rinsing port 7 after fermentation is complete. A frame 9, which connects to the sealing cylinder 13. The frame 9 is the structural foundation of the sealing cylinder 13 and the fermenter.

[0034] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
