[0032] 2. A ventilation pipe is fixedly installed on the top of the processing chamber body of the fermentation processing equipment. The ventilation pipe is connected to the blower. Three branch pipes are also arranged at the bottom of the ventilation pipe. The three branch pipes are respectively connected to the three chambers, and ventilation is carried out to the three chambers through the blower; and solenoid valves are fixedly installed on the three branch pipes. By controlling the switching state of the solenoid valve, the air flow rate is controlled.

The signal line of the first temperature sensor is connected to AI2+ in the expansion module AM06 in the PLC, the signal line of the second temperature sensor is connected to AI3+ in the expansion module AM06 in the PLC, and the signal line of the third temperature sensor is connected to AI0+ in the expansion module AM06 in the PLC, and the real-time temperatures of the three current compartments 223 are displayed on the touch screen.

[0067] The positive pole of the heating plate 225 is connected to Q12.5 of the PLC controller through the relay KA13. The program controls the heating plate 225 to stop heating when it reaches a certain temperature range set by the user on the touch screen (the temperature most suitable for the bacterial agent to implant and reproduce, generally greater than room temperature). When the temperature is lower than the temperature range set by the user on the touch screen, the heating plate 225 starts heating.

[0068] The PLC controller used is the SIEMENS brand S7-200 smart series controller. This PLC controller is equipped with a TPC-1061Ti display screen, which achieves high-speed and stable connection with the PLC controller through the RJ45 Ethernet port, allowing users to intuitively monitor and control the operating status and parameter settings of the PLC.

[0069] The model of the Internet of Things module is FBox-4G-lite. The Internet of Things module is connected to the PLC controller through the RS485 serial communication interface. The FBox-4G-lite module can receive the working data processed by the PLC controller, and use the built-in 4G communication technology to efficiently transmit these data to the nearby communication base station. The data is then further forwarded to the cloud server via the base station for centralized storage and management. This process not only ensures the real-time and integrity of the data, but also provides the possibility of sharing data between different platforms, greatly broadening the application scenarios and flexibility of the system. Through the collaborative work of the touch screen, PLC controller, relay module and Internet of Things module, precise control of the compartment plate motor 14 is achieved, while providing a fault protection mechanism and remote control function, thereby improving the reliability and ease of use of the system.

[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
