Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and in particular to a temperature-controlled feed microbial fermentation tank. Background Technology

[0002] Roughage is rich in crude fiber and protein, including cellulose, hemicellulose, pectin, and lignin, but it is difficult for animals to digest and absorb directly. Consuming roughage can increase the burden on the intestines and cause intestinal diseases. To overcome the shortcomings of traditional feed and promote animal health, roughage is fermented into feed through microbial fermentation. Fermented feed uses microorganisms and compound enzymes as fermentation agents to transform feed ingredients into a unified biological fermentation feed containing microbial cell protein, bioactive small peptide amino acids, active probiotics, and compound enzyme preparations. This product not only compensates for the amino acids that are often lacking in conventional feeds but also rapidly converts the nutrients in other roughage ingredients, enhancing digestibility and absorption.

[0003] The main steps in producing fermented feed are selecting and cultivating microorganisms and inoculating these microorganisms onto feed ingredients. Both microbial cultivation and feed inoculation require controlling appropriate cultivation temperatures. Temperature control is often achieved using temperature-controlled fermenters, such as the microbial constant-temperature fermentation device (publication number CN221166555U) or the microbial constant-temperature fermentation device (publication number CN221296877U). These devices rely on heating pipes located around the material inside the tank to heat it and maintain a suitable temperature. While this method can meet certain temperature requirements, because the heating is conducted from the outside in, the material near the center is difficult to heat quickly and evenly, affecting the fermentation effect. Utility Model Content

[0004] The purpose of this invention is to provide a temperature-controlled feed microbial fermentation tank to solve the problem that the heating method of existing constant temperature fermentation devices transmits heat from the outside to the inside, making it difficult for some materials near the center to be heated quickly and evenly, thus affecting the fermentation effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A temperature-controlled feed microbial fermentation tank, comprising:

[0007] A heating tank, wherein the heating tank is provided with a jacket, and a steam coil connected to an external steam source is provided in the jacket;

[0008] A thermal stirring mechanism includes a motor, a cylinder frame, a rotary connector, and a hollow stirring shaft. The hollow stirring shaft is rotatably installed inside the heating tank with both ends located outside the heating tank. Two rotary connectors are respectively connected to the two outer ends of the hollow stirring shaft for rotation. The air inlet end of one of the rotary connectors is connected to a steam source. The cylinder frame is installed on the heating tank, and the motor is installed on the cylinder frame, with the power output end of the motor connected to the outer end of the hollow stirring shaft.

[0009] A further technical solution is that a temperature gauge is installed on the heating tank.

[0010] A further technical solution is that the swivel connector, which is connected to the steam source, is located inside the cylinder frame.

[0011] A further technical solution is: the swivel connector includes an explosion-proof tube and a housing, the housing is installed on the heating tank and rotatably connected to the outer end of the hollow stirring shaft, the hollow stirring shaft is connected to the inner cavity of the housing, and the two ends of the explosion-proof tube are respectively connected to the inner cavity of the housing and the steam source.

[0012] A further technical solution is that an explosion-proof pressure relief valve is rotatably connected to the outer end of the hollow stirring shaft near the gas outlet.

[0013] A further technical solution is: the hollow stirring shaft has a built-in serpentine tube and an annular filter, the two ends of the serpentine tube are respectively connected to the air outlet of the annular filter, and the air inlet and outlet of the annular filter are adapted to the air inlet and outlet of the hollow stirring shaft.

[0014] A further technical solution is that multiple air holes located in the inner cavity of the shell are uniformly arranged along the axial direction at both outer ends of the hollow stirring shaft.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] This utility model proposes a temperature-controlled feed microbial fermentation tank. Based on traditional fermentation devices, this fermentation tank can stir the materials in the fermentation tank with the help of a thermal stirring mechanism, so as to heat the materials evenly.

[0028] Example 1:

[0029] This implementation example Figure 1 , Figure 2 and Figure 3 As shown, a temperature-controlled feed microbial fermentation tank includes:

[0030] Heating tank 1, heating tank 1 is provided with a jacket 2, and a steam coil 3 connected to an external steam source is provided in the jacket 2;

[0031] The thermal stirring mechanism 4 includes a motor 5, a cylinder frame 6, a rotary connector 7, and a hollow stirring shaft 8. The hollow stirring shaft 8 is rotatably installed inside the heating tank 1 with both ends located outside the heating tank 1. The two rotary connectors 7 are respectively connected to the two outer ends of the hollow stirring shaft 8 for rotation. The air inlet end of one of the rotary connectors 7 is connected to a steam source. The cylinder frame 6 is installed on the heating tank 1, and the motor 5 is installed on the cylinder frame 6. The power output end of the motor 5 is connected to the outer end of the hollow stirring shaft 8.

[0032] This device is suitable for the expansion and fermentation of microbial strains and the fermentation of fermented feed. For example, in the expansion of microbial strains, the selected microbial strains and culture medium are added into the heating tank 1 through the feed inlet of the heating tank 1. Then, under the control of an external controller, the steam output of the steam source is controlled (for example, the controller controls the opening of the solenoid valve on the steam pipeline) to achieve temperature control. At this time, the steam coil 3 and the thermal stirring mechanism 4 are both engaged. Under the action of steam, the steam coil 3 and the thermal stirring mechanism 4 heat the material from the outside and inside, respectively, in order to achieve uniform heating of the material from the inside and outside and to improve heating efficiency and ensure fermentation quality.

[0033] It is worth noting that the heating medium includes, but is not limited to, steam, hot water, and heat transfer oil.

[0034] Preferably, a temperature gauge 9 is provided on the heating tank 1.

[0035] Thermometer 9 is used to monitor the temperature inside the tank and the material in real time to ensure that the temperature is suitable.

[0036] Preferably, the swivel connector 7, which is connected to the steam source, is located inside the cylinder frame 6.

[0037] The rotary connector 7, which is connected to the steam source, has the highest temperature and pressure, and is a moving part. It poses certain safety hazards in terms of sealing. The cylinder frame 6 is used to mitigate the risk of accidental gas leakage and injury to a certain extent.

[0038] Preferably, such as Figure 3 As shown, the swivel connector 7 includes an explosion-proof tube 10 and a housing 11. The housing 11 is mounted on the heating tank 1 and is rotatably connected to the outer end of the hollow stirring shaft 8. The hollow stirring shaft 8 is connected to the inner cavity of the housing 11. The two ends of the explosion-proof tube 10 are connected to the inner cavity of the housing 11 and the steam source, respectively.

[0039] The housing 11 is screwed and connected to the hollow stirring shaft 8, and the rotation of the hollow stirring shaft 8 will not be affected when steam is supplied to the hollow stirring shaft 8.

[0040] An explosion-proof pressure relief valve 12 is rotatably connected to the outer end of the hollow stirring shaft 8 near the air outlet.

[0041] The explosion-proof pressure relief valve 12 is fixed on the tank or other foundation and rotatably connected to the hollow stirring shaft 8, further enhancing the explosion-proof effect.

[0042] Example 2:

[0043] Based on the above embodiments, this embodiment, for example Figure 4 As shown, the hollow stirring shaft 8 has a serpentine tube 13 and an annular filter 14 inside. The two ends of the serpentine tube 13 are connected to the air outlet of the annular filter 14, and the air inlet and outlet of the annular filter 14 are adapted to the air inlet and outlet of the hollow stirring shaft 8.

[0044] While a typical hollow stirring shaft 8 can also provide heating, the presence of some support shafts on the hollow stirring shaft 8 means that even if the support shafts are hollow and connected to the hollow stirring shaft 8, it is still difficult to avoid the problem that steam cannot reach all directions, resulting in some heating dead zones on the hollow stirring shaft 8.

[0045] Therefore, the above problems can be largely avoided by using the serpentine tube 13, and the steam can be effectively passed through the hollow stirring shaft 8 and some of its support shafts, thus improving the heating effect.

[0046] Preferably, the two outer ends of the hollow stirring shaft 8 are evenly provided with a plurality of air holes 15 located in the inner cavity of the shell 11 along its axial direction.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
