Technical Field

[0001] This utility model relates to the field of lactic acid bacteria fermentation technology, specifically to a lactic acid bacteria fermentation culture device. Background Technology

[0002] Lactic acid bacteria fermentation culture equipment is a device specifically designed for the growth and fermentation of lactic acid bacteria. It consists of a fermenter, a stirring system, a temperature control system, an oxygen supply system, and a pressure relief system. It is widely used, ranging from small laboratory-scale fermentation bottles and shake flasks to pilot-scale fermenters and large-scale fermenters for industrial production.

[0003] However, lactic acid bacteria fermentation is prone to the growth of other bacteria. Since most of the current fermentation equipment has a stirring structure that is fixed on the top of the equipment cover and extends into the equipment through the stirring shaft, the structure is complex, making cleaning work cumbersome and increasing the difficulty of hygiene management. At the same time, sampling the fermentation liquid may disrupt the internal fermentation environment and affect the fermentation effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: It includes a fermenter 1, a rotating frame 3 rotatably mounted inside the fermenter 1, a connecting frame 4 connected to the bottom of the rotating frame 3, and multiple permanent magnets 31 connected to one side of the rotating frame 3. The rotating frame 3 is made of demagnetizing or non-magnetic material. A reducer 5 is connected to the bottom of the fermenter 1, a drive motor 6 is connected to one side of the reducer 5, a sealing cover 7 is connected to the top of the fermenter 1, a stirring mechanism 8 is rotatably mounted at the bottom of the sealing cover 7, and a sampling device is connected to the center of the bottom. Mechanism 9, sealing cover plate 7 is connected to the bottom end of sealing cover plate 7 and connecting pipe 10 and connecting pipe 2 11 respectively. The top of fermentation tank 1 is connected to external threaded bracket 12 and tank cover 13 is connected to the top of external threaded bracket 12. One side of fermentation tank 1 is connected to exhaust port 14 and the other side is connected to air inlet port 15. External steam enters the inner cavity of fermentation tank 1 through air inlet port 15 to heat the inside. Condensate and steam can be discharged through exhaust port 14. Since it is a conventional setting, it is not described in detail in the instruction manual.

[0022] Reference Figure 2 and Figure 3 As shown, a rotating shaft 41 is connected to the bottom of the connecting frame 4. The bottom of the rotating shaft 41 passes through the fermentation tank 1 and is connected to the output end of the reducer 5 via a coupling. When the drive motor 6 is started, the reducer 5 can drive the rotating shaft 41 to rotate, thereby driving the rotating frame 3 to rotate in the inner cavity of the fermentation tank 1, thus driving the internal stirring mechanism 8.

[0023] Reference Figure 2As shown in the attached diagram, a sealing ring is connected to the sealing cover plate 7 at the top inner side of the fermentation tank 1, and a pressure bracket 131 is connected to the sealing cover plate 7 at the bottom inner side of the tank cover 13. When the sealing cover plate 7 is installed inside the fermentation tank 1, the outer edge of the sealing cover plate 7 will press against the sealing ring. Then, the tank cover 13 is rotated and installed. At the same time as the tank cover 13 is installed, the pressure bracket 131 will press down on the sealing cover plate 7, so that it fits more tightly with the sealing ring, thereby further ensuring the internal sealing effect. As can be seen from the attached diagram, the top of the tank cover 13 has a through hole for connecting pipe 10 and pipe 21 to the outside.

[0024] Reference Figure 3 As shown, the stirring mechanism 8 includes a rotating ring 81 rotatably disposed at the bottom of the sealing cover plate 7. Multiple magnetic strip frames 82 are connected to the bottom of the rotating ring 81, and stirring blades 83 are connected to the inner side of each magnetic strip frame 82. An installation ring is connected to the bottom of the sealing cover plate 7. The rotating ring 81 is rotatably connected to the installation ring. When the permanent magnet 31 rotates with the rotating frame 3, it is linked with the magnetic strip frames 82 through magnetic linkage. The magnetic strip frames 82 are alternately distributed with positive and negative poles. Through the principle of attraction between opposite poles and repulsion between like poles, the rotation of the permanent magnet 31 can drive the internal magnetic strip frames 82 to rotate, thereby using the stirring blades 83 to stir.

[0025] Reference Figure 4 As shown, the sampling mechanism 9 includes a fixed tube 91 fixedly installed at the bottom of the sealing cover plate 7. A lifting tube 92 is slidably installed inside the fixed tube 91. The bottom end of the lifting tube 92 passes through the fixed tube 91 and is connected to an extraction head 93. A corrugated tube 94 is connected between the extraction head 93 and the fixed tube 91. A strip-shaped through hole is opened on one side of the lifting tube 92, and a valve is connected to the bottom end of the extraction head 93. After fermentation for a certain period of time, the valve below the extraction head 93 is opened to allow some fermentation liquid to enter the extraction head 93. Then the valve is closed, the tank cover 13 is opened, and the lifting tube 92 is pulled upward. The collected fermentation liquid is sucked out through the strip-shaped through hole on one side of the lifting tube 92 for inspection and observation of the fermentation effect. Due to the setting of the corrugated tube 94, fermentation liquid at different levels can be collected while ensuring the internal sealing effect.

[0026] Reference Figure 2 As shown, the top ends of both connecting pipe 10 and connecting pipe 2 11 penetrate the sealing cover plate 7 and are connected to a quick connector 111. Through the quick connector 111, connecting pipe 2 11 can be connected to an external air source device, such as an air compressor. Connecting pipe 10 can be connected to a collection vessel or a material pump. The bottom end of connecting pipe 10 penetrates the stirring mechanism 8 and extends to the bottom of the inner wall of the fermenter 1 to ensure the extraction of fermentation liquid. A docking valve can also be installed through the quick connector 111 to control the internal oxygen supply and nitrogen dioxide discharge.

[0027] The implementation principle of this application is as follows: When using this utility model, the culture medium and lactic acid bacteria inoculum are directly added into the fermenter 1. Alternatively, the sealing cover 7 can be closed first. To ensure the stability of the sealing cover 7, the tank lid 13 is closed and further pressed and fixed using the lower pressure frame 131. Then, the raw materials are added into the fermenter 1 through the connecting pipe 10 and the connecting pipe 2 11. Steam is injected into the fermenter 1 through the air inlet 15 for heating. At the same time, the drive motor 6 is started, which drives the connecting frame 4 through the reducer 5, causing the internal rotating frame 3 to drive the permanent magnet 31 to rotate. The stirring mechanism 8 inside the fermenter is activated to ensure uniform heating and even mixing of the culture medium and lactic acid bacteria. During the process, oxygen can be injected into the fermenter 1 through the discharge pipe 10 and carbon dioxide can be discharged through the air inlet pipe 11. After fermentation for a period of time, the sampling mechanism 9 can be used to sample the fermentation effect. After use, the fermentation liquid can be removed and the stirring mechanism 8 and sampling mechanism 9 can be removed through the sealing cover 7 to clean the inside of the fermenter 1 effectively without dead corners, making it easy to clean.
