Description

Technical Field

[0001] The present application relates to the technical field of feed production, and in particular to a rapid bacterial culture fermentation tank. Background Art

[0002] In recent years, the negative impact of the use of antibiotics has become increasingly apparent, and calls for a ban on antibiotics have been growing, forcing the pig industry to choose antibiotic substitutes. A large number of experimental scientific research and pig production practices have shown that lactic acid bacteria have very outstanding advantages and can replace antibiotics as a pig feed additive. Lactic acid bacteria adhere to the surface of the gastrointestinal tract, produce antimicrobial peptides, compete with pathogens for binding sites on the intestinal epithelium, or regulate the host immune system, thereby regulating the intestinal environment, inhibiting or eliminating pathogens in the gastrointestinal tract, balancing the intestinal microbiome, enhancing the immune capacity of the intestinal mucosa and maintaining the intestinal barrier function, which is beneficial to the healthy development of pigs.

[0003] Therefore, a large amount of lactic acid bacteria is needed in the production of pig feed, and lactic acid bacteria are usually obtained through artificial cultivation. During the process of bacterial expansion and fermentation, the culture environment needs to be maintained within a suitable temperature range to ensure the expansion and fermentation efficiency of the bacterial strain, so a fermentation tank that can quickly expand the culture is needed.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] The present application discloses a rapid bacterial culture fermentation tank. Figure 1 The bacterial strain rapid expansion fermentation tank includes a tank body 1, the side wall of the tank body 1 is cylindrical, and the axis of the tank body 1 is vertically arranged. A support leg 13 is fixedly connected to the outer wall of the tank body 1 for supporting the tank body 1. A feed pipe 14 is arranged on the top of the tank body 1, and the feed pipe 14 is used to input raw materials, such as bacterial strains, nutrients and water. The raw materials can form a mixed bacterial liquid after mixing in the tank body 1; an end cap is hinged at the end of the feed pipe 14. A discharge pipe 15 is arranged at the bottom of the tank body 1 for discharging the fermented product in the tank body 1. A mud pump 9 is installed on the discharge pipe 15. Since the mixed bacterial liquid after fermentation is viscous, the mixed bacterial liquid in the tank body 1 can be pumped out after the mud pump 9 is turned on.

[0037] Reference Figure 2The wall of the tank body 1 is hollow, so an interlayer 11 is formed in the wall of the tank body 1. An oil inlet pipe 16 is arranged on the outer wall of the top of the tank body 1, and the oil inlet pipe 16 is connected to the interlayer 11, so that hot oil can be easily injected into the interlayer 11 through the oil inlet pipe 16. An oil outlet pipe 17 is arranged on the outer wall of the bottom of the tank body 1, and the oil outlet pipe 17 is connected to the interlayer 11, so that the oil with a lower temperature in the interlayer 11 can be easily discharged through the oil outlet pipe 17. The oil inlet pipe 16 and the oil outlet pipe 17 are both threadedly connected with a blocking cover, and the opening and closing of the oil inlet pipe 16 and the oil outlet pipe 17 can be controlled as needed. Before fermentation, the bacteria and nutrients are put into the tank body 1, and then cold water is added to the tank body 1; then hot oil is introduced into the interlayer 11 through the oil inlet pipe 16, and the heat of the hot oil can be transferred to the mixed bacterial liquid in the tank body 1 through the inner wall of the tank body 1, so that the mixed bacterial liquid can be heated up, so that the bacteria are in a suitable environment for fermentation, which helps to ensure the fermentation efficiency. A thermometer 5 is also installed on the tank body 1, and the sensing end of the thermometer 5 is located inside the tank body 1, so it is convenient to check the temperature inside the tank body 1 through the thermometer 5, so as to judge the amount of hot oil to be added.

[0038] Furthermore, a heat conductor 2 is provided on the tank body 1. The heat conductor 2 is a rod-shaped structure, and the heat conductor 2 is made of copper, so the heat conductivity of the heat conductor 2 is good. There are multiple heat conductors 2, and they are arranged at intervals on the inner wall of the bottom end of the tank body 1. The heat conductor 2 is fixedly connected to the inner wall of the tank body 1, and one end of the guide is located in the interlayer 11 and can contact the hot oil in the interlayer 11; the other end of the heat conductor 2 is located in the tank body 1 and can contact the mixed bacterial liquid; therefore, the heat conductor 2 can further transfer the heat in the hot oil to the mixed bacterial liquid, which can accelerate the heating process.

[0039] Reference Figure 1 The top wall of the tank body 1 is provided with an observation port 12, and a magnifying glass 6 is installed on the wall of the observation port 12. The shape of the magnifying glass 6 is the same as that of the observation port 12; therefore, the fermentation condition in the tank body 1 can be observed through the magnifying glass 6, and the product can be discharged in time after the fermentation is completed. A lighting lamp is also installed on the inner wall of the tank body 1, so that the brightness inside the tank body 1 can be improved, which is convenient for users to observe.

[0040] Reference Figure 2, a stirring assembly 3 is also provided on the tank body 1, and the stirring assembly 3 includes a rotating power member, a rotating shaft 32 and a stirring rod 33. The rotating power member is a motor 31, and the motor 31 is fixedly connected to the outer wall at the top of the tank body 1 by bolts, and the output shaft of the motor 31 is vertically downward, and the output shaft of the motor 31 is coaxial with the axis of the tank body 1. The rotating shaft 32 is coaxially fixedly connected to the output shaft of the motor 31, and the rotating shaft 32 is located in the tank body 1. The stirring rod 33 is vertically fixedly connected to the rotating shaft 32, and the stirring rod 33 is provided with a plurality of stirring rods and evenly spaced. Therefore, after the motor 31 is started, the rotating shaft 32 can be driven to rotate, and the rotating shaft 32 can drive the stirring rod 33 to rotate, thereby accelerating the mixing of the strain and the nutrient solution, making the mixing more sufficient, and facilitating the subsequent fermentation.

[0041] The stirring rod 33 is fixedly connected with a connecting piece 4, which is a rectangular thin sheet structure. Therefore, the setting of the connecting piece 4 can increase the contact area between the stirring rod 33 and the nutrient solution, which helps to enhance the stirring effect. The connecting piece 4 is provided with a mesh 41, and the mesh 41 is provided in multiple numbers and arranged in an array; therefore, during the stirring process, the nutrient solution can pass through the mesh 41, thereby reducing the resistance encountered during the rotation of the connecting piece 4. In addition, when the connecting piece 4 rotates, the foam generated during the fermentation of the bacteria can also be dispersed, so that it is convenient to observe the fermentation situation in the tank body 1 through the magnifying glass 6.

[0042] The implementation principle of Example 1 is as follows: first, bacteria, nutrients and water are added into the tank body 1 through the feed pipe 14, and then the motor 31 is started, and the motor 31 drives the stirring rod 33 to rotate through the rotating shaft 32, so that the bacteria are evenly distributed; then hot oil is introduced into the interlayer 11 through the oil inlet pipe 16, and the heat of the hot oil is transferred to the mixed bacteria liquid in the tank body 1 through the inner wall of the tank body 1 and the heat conducting member 2, so that the mixed bacteria liquid in the tank body 1 can be heated to a suitable temperature, thereby ensuring the fermentation rate of the bacteria; after the bacteria fermentation is completed, the mud pump 9 is turned on to discharge the mixed bacteria liquid in the tank body 1.

[0043] Example 2

[0044] Reference Figure 3 , the difference between this embodiment and embodiment 1 is that a brush plate 7 is further provided in this embodiment.

Brush bristles 71 are provided on the brush plate 7, and the brush bristles 71 abut against the inner wall of the tank body 1. Therefore, when the brush plate 7 slides, the brush bristles 71 can brush off the raw materials adhering to the inner wall of the tank body 1, thereby reducing waste.

[0045] The tank body 1 is provided with a driving mechanism 8, which includes a driving gear 81, a driven gear ring 82 and a transmission assembly 83.

The connecting shaft 10 is arranged on the tank body 1 so as to rotate around its own axis. The driving gear 81 is coaxially fixedly connected to one end of the connecting shaft 10 located in the tank body 1. The driven gear ring 82 is an inner gear ring with a vertical axis, and the outer wall of the driven gear ring 82 is fixedly connected to the brush plate 7. The driven gear ring 82 is meshed with the driving gear 81. The transmission assembly 83 is used to drive the driving gear 81 to rotate. After the driving gear 81 rotates, it can drive the driven gear ring 82 to rotate, thereby driving the brush plate 7 to rotate, and the inner wall of the tank body 1 is cleaned.

[0046] The transmission assembly 83 is arranged at the top of the tank body 1, and the transmission assembly 83 is located outside the tank body 1. The transmission assembly 83 includes a driving sprocket 831, a driven sprocket 832 and a chain 833. The driving sprocket 831 is coaxially fixedly connected to the output shaft of the motor 31, and the driven sprocket 832 is coaxially fixedly connected to one end of the connecting shaft 10 located outside the tank body 1. The chain 833 is wound between the driving sprocket 831 and the driven sprocket 832. Therefore, when the motor 31 drives the rotating shaft 32 to rotate, the motor 31 can also drive the driving sprocket 831 to rotate, the driving sprocket 831 drives the driven sprocket 832 to rotate through the chain 833, and the driven sprocket 832 drives the driving gear 81 to rotate through the connecting shaft 10.

[0047] The implementation principle of Example 2 is as follows: during the fermentation process, the motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the stirring rod 33 and the connecting piece 4 to rotate, thereby stirring the nutrient solution in the tank body 1; at the same time, the motor 31 also drives the driving sprocket 831 to rotate, the driving sprocket 831 drives the driven sprocket 832 to rotate through the chain 833, the driven sprocket 832 drives the driving gear 81 to rotate, the driving gear 81 drives the driven gear ring 82 to rotate, and the driven gear ring 82 drives the brush plate 7 to operate, and the brush plate 7 moves along the inner wall of the tank body 1, so that the raw materials adhering to the inner wall of the tank body 1 can be brushed off, thereby ensuring the bacterial strain content in the final product.

[0048] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application.
