[0022] Through the Internet of Things connection device, the controller 19 establishes a communication connection with the Internet of Things platform. The staff can log in to the Internet of Things platform through a remote terminal (such as a mobile phone or a computer) and send control instructions based on the real-time data of the detection unit. The Internet of Things platform transmits these instructions to the controller 19 through the Internet of Things connection device. The controller 19 controls the corresponding solenoid valve or electric valve according to the received instructions, thereby realizing remote adjustment of the internal pressure of the fermentation tank 1.

[0024] A discharge pipe 16 is fixedly installed at the bottom of the fermentation tank 1, a heating pipe 18 is provided in the tank wall of the fermentation tank 1, an exhaust pipe 12 and a feed pipe 14 are fixedly installed on the sealing cover 2, and a solenoid valve 13 is provided in the discharge pipe 16, the exhaust pipe 12 and the feed pipe 14, and the heating pipe 18 and the solenoid valve 13 are controlled and connected to the controller 19; a connecting pipe 4 is fixedly installed vertically at the bottom of the sealing cover 2, the top of the connecting pipe 4 is sealed and a plurality of discharge ports are evenly opened along the circumference of the upper part, an auger 5 connected to the driving mechanism is rotatably installed in the connecting pipe 4, and the driving mechanism is controlled and connected to the controller 19.

[0025] A driving box 11 is fixedly installed on the top of the sealing cover 2, and a cavity is opened inside the sealing cover 2. The driving mechanism includes a driving motor 10 fixedly installed in the driving box 11 and a driving assembly arranged in the cavity, and the driving motor 10 is transmission-connected to the driving assembly; the driving assembly includes a driving gear 8 and a driven gear 9 rotatably installed in the cavity, the driving gear 8 is transmission-connected to the driving motor 10 and the auger 5 respectively, there are multiple driven gears 9, and the multiple driven gears 9 are evenly distributed along the circumferential side of the driving gear 8, and are respectively meshed with the driving gear 8 for transmission, and the driven gears 9 are respectively transmission-connected to the corresponding rotating shafts 6.

[0026] There are many ways to connect the driving gear 8 with the drive motor 10 and the auger 5, for example: a drive shaft is rotatably installed in the middle of the cavity, the driving gear 8 is sleeved on the drive shaft, the top end of the drive shaft extends into the drive box 11 and is fixedly connected to the output shaft of the drive motor 10 through a coupling, the lower end of the drive shaft extends into the connecting pipe 4 and is fixedly connected to the rotating shaft of the auger 5 through a coupling, and there are many ways to connect the driven tooth path with the corresponding rotating shaft 6, for example: a drive rod is rotatably installed in the cavity, the driven gear 9 is sleeved on the drive rod, and the lower end of the drive rod passes through the sealing cover 2 and is fixedly connected to the rotating shaft 6 through a coupling; the center of the bottom of the fermenter 1 is recessed downward to form a collecting trough, the lower ends of the connecting pipe 4 and the auger 5 are extended into the collecting trough, and the upper end of the discharge pipe 16 is connected to the collecting trough; the fermentation liquid can be collected through the collecting trough, which is not only convenient for the fermentation liquid to be transported upward through the auger 5, but also convenient for the fermentation liquid to be completely discharged through the discharge pipe 16; a plurality of rotating shafts 6 are installed on the outside of the connecting pipe 4 along the circumference, the stirring shaft 6 is drivingly connected to the rotating shaft of the auger 5, and a plurality of stirring blades 7 are fixedly installed on the rotating shaft 6 at intervals along the vertical direction.

[0027] When we use the fermentation device for biological fermentation, we first inject the substances required for fermentation into the fermentation tank 1 through the feed pipe 14, and then start the heating tube 18 and the drive motor 10. The heating tube 18 can provide a suitable fermentation temperature for the fermented material. The drive motor 10 drives the driving gear 8 to rotate, and drives the rotating shaft 6 to rotate through the meshing transmission of the driving gear 8 and the driven gear 9, thereby driving the stirring blade 7 to stir the substances in the fermentation tank 1. At the same time, the rotation of the driving gear 8 will synchronously drive the auger 5 to rotate. The auger 5 transports the substances at the bottom of the fermentation tank 1 upward and discharges them through the discharge port on the connecting pipe 4, thereby mixing the substances at the top and bottom of the fermentation tank 1, and further fully mixing the fermentation matrix and the yeast.

[0028] After the material in the fermentation tank 1 ferments for a period of time, the pressure in the fermentation tank 1, the dissolved oxygen content or the pH value of the fermented material will change. At this time, the staff can remotely control the exhaust pipe 12 and the high-pressure gas tank 15 through the Internet of Things to change the pressure in the fermentation tank 1, and adjust the dissolved oxygen content and the pH value of the fermented material through the oxygen supply equipment 17 and the acid-base solution storage tank. When the staff injects oxygen or acid-base solution into the fermentation tank 1, the drive motor 10 is started at the same time, thereby driving the auger 5 and the stirring blade 7 to rotate at the same time, so that the dissolved oxygen content and the pH value of the upper and lower parts of the fermented material are the same.

[0029] When the internal pressure of the fermentation tank 1 needs to be increased, the staff can send instructions to the IoT cloud platform through the remote operation interface (such as mobile phone APP, computer software, etc.), and the IoT cloud platform will send the instructions to the controller 19. After receiving the instructions, the controller 19 controls the electric valve of the high-pressure gas tank 15 to open, and injects nitrogen and other gases into the fermentation tank 1, thereby increasing the pressure inside the fermentation tank 1.

[0030] When it is necessary to reduce the internal pressure of the fermentation tank 1, the staff can also send instructions to the IoT cloud platform through the remote operation interface. After the IoT cloud platform sends the instructions to the controller 19, the controller 19 controls the solenoid valve of the exhaust pipe 12 to open, and discharges the gas inside the fermentation tank 1, thereby reducing the pressure inside the fermentation tank 1; through the remote control function of the Internet of Things, the staff can understand the pressure inside the fermentation tank 1 in real time, and adjust the pressure at any time as needed to ensure the smooth progress of the fermentation process.
