Technical Field

[0001] This utility model relates to the field of probiotic cultivation, and more specifically, to a constant temperature culture system for bacterial strains. Background Technology

[0002] Probiotics are a class of microorganisms that are beneficial to the host. They can help maintain a healthy digestive system in the human gut and help enhance immune function.

[0003] When cultivating probiotics, it is necessary to first select a suitable strain and then determine its culture medium. Because probiotics have harsh growth conditions, they need to be placed in a special incubator that can maintain a constant growth environment, such as temperature and humidity.

[0004] Currently, large-scale microbial fermentation equipment is expensive, and small-scale farms face significant cost pressures when purchasing it. Therefore, there is an urgent need for a simple and low-cost microbial constant-temperature propagation system. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0020] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, the present invention provides a constant temperature culture system for microbial inoculum, including a fermentation tank 1. The fermentation tank 1 is used to store the material to be fermented, and the fermentation tank 1 is equipped with a microbial inoculum conveying pipe, a water inlet pipe, a bottom material conveying pipe, and a material output pipe. The microbial inoculum conveying pipe is used to convey microbial inoculum into the fermentation tank 1, the water inlet pipe is used to convey tap water into the fermentation tank 1, the bottom material conveying pipe is used to convey the bottom material for fermentation into the fermentation tank 1, and the material output pipe is used to output the fermented material from the fermentation tank 1.

[0022] In this invention, to ensure more thorough output of fermented material from the fermentation tank 1, the material output pipe is preferably located at the bottom of the fermentation tank 1. To simplify the structure of the fermentation tank 1, a T-junction can be installed on the water inlet pipe, and the outlet ends of the inoculum delivery pipe and the bottom material delivery pipe can be connected to the other two ports on the T-junction. The connection between the water inlet pipe, the inoculum delivery pipe, the bottom material delivery pipe, and the fermentation tank 1 can be adjusted by controlling the T-junction. Simultaneously, an electric or manual on / off valve can be installed at the inlet end of the water inlet pipe, the inlet end of the bottom material delivery pipe, and the inlet end of the inoculum delivery pipe.

[0023] Of course, if a float valve is installed at the outlet end of the water inlet pipe, the outlet ends of the inoculum delivery pipe and the bottom material delivery pipe cannot be connected in parallel to the water inlet pipe through a T-connector. In this case, the inoculum delivery pipe and the bottom material delivery pipe can be connected in parallel and then connected to fermentation tank 1, or they can be directly connected to fermentation tank 1 separately.

[0024] Since the fermentation of materials must be completed in a closed environment, therefore, Figure 2As shown, a cover plate 3 is also installed on the fermentation tank 1. When the cover plate 3 is placed on the fermentation tank 1, the fermentation tank 1 is in a sealed state. A constant temperature heating pipe 4 extending to the bottom of the fermentation tank 1 is also installed on the cover plate 3, and the heating part of the constant temperature heating pipe 4 is located at the bottom of the fermentation tank 1, so that the heating part of the constant temperature heating pipe 4 heats the material in the fermentation tank 1 when it is working. At the same time, a stirrer is also installed on the cover plate 3. The stirrer includes a stirring shaft 5 rotatably installed on the cover plate 3. The stirring shaft 5 extends to the bottom of the fermentation tank 1, and the extended end of the stirring shaft 5 is also equipped with stirring blades 6, so that the stirring shaft 5 drives the stirring blades 6 to rotate synchronously while rotating, thereby stirring the material in the fermentation tank 1. This not only ensures that the inoculum, base material, and tap water fed into the fermentation tank 1 are evenly mixed, but also avoids uneven temperature of the material caused by the material being in a static state during the heating process of the constant temperature heating pipe 4, making the fermentation of the material more uniform and faster.

[0025] To ensure the smooth operation of the agitator, such as Figure 1 As shown, a drive motor 8 is also installed on the cover plate 3. The output end of the drive motor 8 is connected to the stirring shaft 5 of the stirrer, so that the drive motor 8 drives the stirring shaft 5 to rotate at the same time. The stirring shaft 5 drives the stirring blades 6 to rotate synchronously, thereby stirring and mixing the materials in the fermentation tank 1.

[0026] In this invention, a thermostat 15 is also installed on the cover plate 3. The thermostat 15 may be of model including but not limited to XMTA-2201, and its output end is connected to the input end of the constant temperature heating tube 4, so that the thermostat 15 can control the heating temperature of the constant temperature heating tube 4. Simultaneously, a hollow shaft 17 extending into the fermentation tank 1 is also installed on the cover plate 3. A temperature sensor 16 is installed at the extended end of the hollow shaft 17. The model and specifications of the temperature sensor 16 are selected according to the requirements of measurement accuracy and environmental adaptability. The temperature sensor 16 can monitor the temperature of the contents of the fermentation tank 1. The material temperature is detected, and the output terminal of the temperature sensor 16 is connected to the input terminal of the temperature controller 15. The output terminal of the temperature controller 15 is connected to the relay of the constant temperature heating tube 4, so that the temperature information detected by the temperature sensor 16 can be transmitted to the temperature controller 15. After the temperature information detected by the temperature sensor 16 is transmitted to the temperature controller 15, it can be compared with the temperature information preset by the temperature controller 15. Based on the comparison result, the temperature controller 15 adjusts the relay of the constant temperature heating tube 4, thereby regulating the operating power and start / stop of the constant temperature heating tube 4.

[0027] When the temperature information detected by the temperature sensor 16 is lower than the preset temperature information of the temperature controller 15 after being transmitted to the temperature controller 15, the temperature controller 15 sends a start signal to the relay of the constant temperature heating tube 4. After receiving the start signal, the relay of the constant temperature heating tube 4 starts, causing the constant temperature heating tube 4 to start running. When the temperature information detected by the temperature sensor 16 is higher than or equal to the preset temperature information of the temperature controller 15 after being transmitted to the temperature controller 15, the temperature controller 15 sends a stop signal to the relay of the constant temperature heating tube 4. After receiving the stop signal, the relay of the constant temperature heating tube 4 stops, causing the constant temperature heating tube 4 to stop heating.

[0028] In order to cover the drive motor 8, temperature controller 15, etc., a housing 2 for covering the drive motor 8 and temperature controller 15 is also installed on the cover plate 3; at the same time, in order to facilitate sending the preset temperature to the temperature controller 15, a rotary adjustment switch 12 is also installed on the cover plate 3. The output end of the rotary adjustment switch 12 is connected to the input end of the temperature controller 15, so that the operator can send the corresponding preset temperature to the temperature controller 15 through the rotary adjustment switch 12, thereby realizing the preset fermentation temperature.

[0029] To prevent the temperature of the water supplied to fermentation tank 1 from being too high, a float valve is installed at the outlet end of the water inlet pipe. When tap water is supplied to fermentation tank 1 through the water inlet pipe, the float valve automatically closes when the liquid level in fermentation tank 1 reaches the installation height of the float valve, and automatically opens when the liquid level in fermentation tank 1 is lower than the installation height of the float valve, thus preventing too much or too little tap water from being supplied to fermentation tank 1.

[0030] In this invention, in order to minimize the shaking of the stirrer during rotation, such as... Figure 2 As shown, two fixing rods 18 can also be fixedly installed on the cover plate 3. The two fixing rods 18 are arranged symmetrically with the central axis of the stirrer as the reference, and the two fixing rods 18 extend into the fermentation tank 1. The extended ends of the two fixing rods 18 are welded together with a fixing plate 7. At the same time, when the stirrer is installed, the stirring shaft 5 on the stirrer passes through the fixing plate 7 and extends to the bottom of the fermentation tank 1, so that the stirring shaft 5 and the fixing plate 7 rotate together. When the stirring shaft 5 rotates, the stirring shaft 5 is restricted by the fixing plate 7, so that the rotation of the stirring shaft 5 is more stable.

[0031] To avoid the mounting plate 7 obstructing the installation of the thermostatic heating tube 4, and to minimize the transfer of heat from the thermostatic heating tube 4 to the mounting plate 7 during the heating process, such as Figure 3 As shown, the fixed plate 7 is also provided with a groove 11 for avoiding the constant temperature heating tube 4. The shape of the groove 11 is not limited, and the opening of the groove 11 is larger than the constant temperature heating tube 4, so that the constant temperature heating tube 4 will not contact the groove wall of the groove 11 while passing through the groove 11.

[0032] In this utility model, the fermentation tank 1 can be a large-capacity plastic water tank available on the market. Therefore, in order to facilitate the installation of the fermentation tank 1, the constant temperature expansion system for the microbial culture also includes a base 9, so that the fermentation tank 1 can be placed directly on the base 9 during installation. At the same time, the fermentation tank 1 is also covered with a frame structure 13, which can be made of metal.

[0033] To facilitate the fixed installation of the cover plate 3, the existing large-capacity plastic water bucket also has two handles 10 on the top, and the two handles 10 have mounting rods 14 passing through them. The mounting rods 14 are fixed to the frame structure 13 by bolts, thereby fixing the large-capacity plastic water bucket to the frame structure 13. When the cover plate 3 needs to be installed, the opposite sides of the cover plate 3 can be fixed to the two mounting rods 14 by bolts, making the installation and disassembly of the cover plate 3 more convenient.

[0034] When fermentation of materials is required, tap water is introduced into fermentation tank 1 through the inlet pipe. When the water level in fermentation tank 1 reaches the installation height of the float valve, the float valve automatically closes and the inlet pipe is shut off, stopping the supply of tap water into fermentation tank 1. Then, the inoculum is transported into fermentation tank 1 through the inoculum delivery pipe, and the substrate is transported into fermentation tank 1 through the substrate delivery pipe. Next, the drive motor 8 runs, driving the stirring shaft 5 to rotate, causing the stirring blades 6 on the stirring shaft 5 to rotate synchronously. The stirring blades 6 evenly mix the inoculum, substrate, and tap water in fermentation tank 1.

[0035] Next, the operator rotates the rotary adjustment switch 12 to set the fermentation temperature. The rotary adjustment switch 12 transmits the preset fermentation temperature to the temperature controller 15. The temperature sensor 16 detects the temperature of the material in the fermentation tank 1 and transmits the detected temperature information to the temperature controller 15. When the temperature detected by the temperature sensor 16 is lower than the preset temperature information of the temperature controller 15, the temperature controller 15 sends a start signal to the relay of the constant temperature heating tube 4. Upon receiving the start signal, the relay of the constant temperature heating tube 4 starts, thus maintaining the constant temperature. When the constant temperature heating tube 4 starts operating, the drive motor 8 runs during the operation of the constant temperature heating tube 4. The drive motor 8 drives the stirring shaft 5 to rotate, causing the stirring blades 6 on the stirring shaft 5 to rotate synchronously, so that the stirring blades 6 can stir and mix the materials in the fermentation tank 1. When the temperature information detected by the temperature sensor 16 is higher than or equal to the preset temperature information of the temperature controller 15, the temperature controller 15 sends a stop signal to the relay of the constant temperature heating tube 4. After receiving the stop signal, the relay of the constant temperature heating tube 4 stops heating, and the drive motor 8 stops running.

[0036] Once the material in fermentation tank 1 has finished fermenting, open the material output pipe to transport the material in fermentation tank 1 to the next device.

[0037] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
