Description

Technical Field

[0001] The utility model relates to the technical field of microbial fermentation, and specifically relates to a culture fermentation tank for probiotic processing. Background Technique

[0002] Probiotic fermentation brings significant benefits to the food industry and human health through multiple mechanisms such as regulating the flora, enhancing nutrition, strengthening immunity, and improving quality. In the future, with the optimization of strain screening and fermentation processes, its application fields will be further expanded to functional foods, precision nutrition, and disease prevention.

[0003] The patent document with the publication number CN215799576U discloses a fermentation device for culturing probiotics, which can make the probiotics inside the fermentation tank receive uniform heat and make the probiotics fully contact with oxygen. It includes a fermentation tank, a driving motor is arranged at the top of the fermentation tank, a feed pipe is arranged at the top of the right part of the fermentation tank, a sealing cover is arranged at the top of the feed pipe, discharge valves are arranged at the left and right parts of the bottom of the fermentation tank, a heater is arranged inside the fermentation tank, a driving shaft is arranged between the output end of the motor and the top of the heater, the driving shaft is rotatably connected to the top of the heater, a connecting shaft is arranged at the bottom of the driving shaft, several connecting rods are arranged around the driving shaft, a paddle is arranged at the bottom of each connecting rod, several release pipes are arranged at the bottom inside the fermentation tank, several through holes are arranged on the pipe wall of each release pipe, and an exhaust valve is arranged at the left part of the top of the fermentation tank. However, the following problems still exist in the actual use of this patent:

[0004] This fermentation device injects oxygen from the bottom of the culture solution through the release pipe. However, since the through holes on the release pipe are exposed inside the fermentation tank, when oxygen supply is not required, the probiotic fermentation liquid is likely to enter the release pipe through the through holes, resulting in backflow. At the same time, it is difficult to remove the fermentation liquid in the release pipe. Moreover, as the paddle rotates with the connecting rod to stir the fermentation liquid for a long time, the fermentation liquid is likely to rotate with the paddle, resulting in a low mixing efficiency. Therefore, the practicability of this fermentation device is poor.

[0005] Therefore, a culture fermentation tank for probiotic processing is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a culture fermentation tank for probiotic processing, so as to solve the problems raised in the above-mentioned background technology. Currently, the fermentation device injects oxygen from the bottom of the culture solution through a release pipe. However, since the through holes on the release pipe are exposed inside the fermentation tank, when oxygen supply is not required, the probiotic fermentation liquid easily enters the release pipe through the through holes, resulting in backflow. At the same time, it is difficult to remove the fermentation liquid in the release pipe. Moreover, as the paddle follows the rotation of the connecting rod to achieve long-term stirring of the fermentation liquid, the fermentation liquid easily rotates with the paddle, resulting in a low mixing efficiency.

[0029] Please refer to Figures 1-6, the present utility model provides a technical solution: a culture fermentation tank for probiotic processing, including a fermentation tank body 1; a motor 3 is installed above the fermentation tank body 1; further including: a transmission gear 2 is rotatably connected to one side of the top end of the fermentation tank body 1, a driven gear 4 is meshed and connected to one side of the transmission gear 2, a rotating shaft 5 is fixedly connected to the bottom of the driven gear 4, a ventilation pipe 6 is rotatably connected to the middle of the rotating shaft 5, a lapping block 7 is fixedly connected to the middle of the lower end of the ventilation pipe 6, a butting block 8 is lapped on the bottom of the lapping block 7, a connecting column 9 is fixedly connected to the bottom of the butting block 8, a return spring 10 is sleeved on the outside of the connecting column 9, a fixing rod 11 is fixedly connected to the bottom of the return spring 10, an upper sealing block 12 is fixedly connected to the middle of the connecting column 9, a lower sealing block 13 is fixedly connected to the lower end of the connecting column 9, an injection port 14 is slidably connected to the outside of the lower sealing block 13, and a flow dividing plate 15 is lapped on the upper end of the injection port 14; the upper end of the transmission gear 2 is fixedly connected to the output end of the motor 3, and the upper end of the rotating shaft 5 is rotatably connected to the middle of the top end of the fermentation tank body 1; the lower end of the ventilation pipe 6 passes through the rotating shaft 5 and is threadedly connected to the injection port 14, and the upper and lower ends of the flow dividing plate 15 are respectively lapped with the bottom of the rotating shaft 5 and the injection port 14; the fixing rod 11 is fixedly connected to the inner wall of the lower end of the ventilation pipe 6, the connecting column 9 is slidably connected to the middle of the fixing rod 11, and the two ends of the return spring 10 are respectively lapped with the bottom surface of the butting block 8 and the top surface of the fixing rod 11; the outside of the upper end of the upper sealing block 12 is lapped with the middle of the bottom of the ventilation pipe 6. By threading the injection port 14 under the ventilation pipe 6, it is convenient to clean the residual fermentation liquid in the middle of the injection port 14, and the double-layer sealing effect of the lower end of the ventilation pipe 6 is realized through the upper sealing block 12 and the lower sealing block 13, making the sealing effect of the ventilation pipe 6 better and preventing the fermentation liquid from entering the ventilation pipe 6.

[0030] Wherein, a stirring blade 16 is fixedly connected to the outside of the rotating shaft 5, a moving plate 17 is slidably connected to one side of the stirring blade 16, a limiting frame 18 is slidably connected to the upper end of the moving plate 17, a sliding block 19 is fixedly connected to one side of the top end of the moving plate 17, and a sliding groove 20 is slidably connected to the upper end of the sliding block 19; the stirring blade 16 and the moving plate 17 are symmetrically arranged on both sides of the rotating shaft 5, and the limiting frame 18 is fixedly connected to the upper end of the rotating shaft 5; the sliding groove 20 is opened on the top surface of the inner wall of the fermentation tank body 1.
