2. System configuration:

(1) Host (optional): Dell computer; Highly integrated, the system consists of a control cabinet and a tank body. The control cabinet is made of 304L stainless steel, which is easy to clean; The nominal volume of the tank is 3L, and the working volume is 0.5-2.1L;

(2) Temperature control system: Pt100 temperature probe, temperature control range: 8 ℃ -45 ℃ above ambient temperature, accuracy: ± 0.1 ℃; Heating method: electric heating film, controllable heating output, ensuring that the temperature overshoot does not exceed 0.3 ℃ during the initial heating process;

(3) PH detection and control: digital pH probe, control range: 2-12, control accuracy: ± 0.01; Optional control mode, controlled through feeding or ventilation methods; Flexible setting of dead zone range, acid and alkali dead zones can be set separately; One click online recalibration can be performed during the cultivation process to ensure the accuracy of pH.

(4) DO detection and control: digital optical DO probe; Control range: 0-100%, control accuracy: ± 2%; Multiple control modes are available: air constant ventilation, oxygen conditions, or proportional ventilation of air and oxygen; Optional three gas mode or four gas mode, suitable for different cultivation process requirements;

(5) Mixing control: using servo motor to ensure mixing accuracy, speed range: 0-300rpm, control accuracy: ± 1rpm; The system can automatically detect faults in the mixing motor and issue an alarm;

(6) Ventilation system: 4 gas interfaces are reserved and equipped with corresponding flow meters; Air, oxygen, and CO2 are equipped with mass flow meters with a range of 0-1000ml/min and an accuracy of 0.1ml/min. The mass flow meter has no dead zone within the range and can be controlled starting from 0.1ml/min; Equipped with a flow meter with a measuring range of 0-1000ml/min; The ventilation volume of air, oxygen, and CO2 can be accumulated, and the accumulated flow rate can be reset separately. Real time flow rate and accumulated flow rate data are stored in the report;

(7) Peristaltic pump (optional): Three variable speed Karchuan peristaltic pumps; The peristaltic pump adopts a flip type, which can quickly and conveniently replace the silicone tube, with a speed range of 0-180rpm; The corresponding functions of the peristaltic pump can be switched at any time, including acid, alkali, defoaming, feeding, receiving, etc; The flow rate of the peristaltic pump can be calibrated, the flow rate can be accumulated, and the accumulated flow rate can be reset separately;

(8) User management function: User management is divided into three levels of permissions, namely operators, process engineers, and system administrators; Unauthorized users are unable to modify system parameters; The system can record the operation records of the corresponding logged in users and achieve audit tracking function;

(9) Report, curve and data acquisition functions: The controller adopts Siemens PLC; Users can easily create new reports, with flexible customization of report batch numbers and customizable data recording cycles, with a minimum recording cycle of 1 second; Reports can be flexibly queried by batch number or time, and can be exported as Excel or PDF files via USB as needed; Corresponding parameter curves can be selected as needed, and curve coordinates can be flexibly set; The corresponding curve can be flexibly queried through batch number or time, and exported via USB; It is necessary to provide a PLC data point table and open the data collection function to ensure that users can directly read and modify all required corresponding parameters from the PLC;

(10) Tank system: The tank is made of single-layer borosilicate glass and can withstand high temperature sterilization at 121 ℃; The top cover and various interfaces are made of 316L stainless steel and electrolytic polished; The top cover interface includes 6 M18 electrode interfaces (including three needle feeding ports), 6 ø 10 interfaces, 2 ø 12 interfaces, 3 ø 6 interfaces, and one M32 stirring blade interface; The stirring blade is a ø 45 45 ° inclined blade; The ventilation tube adopts an L-shaped design with a 7 * 1mm aperture, which can replace a 50 μ m microbubble ventilation tube; Equipped with temperature sleeve, 6mm single needle feeding head * 3, three needle feeding * 1, culture medium/harvesting tube * 1, sampling tube * 1, exhaust tube * 1, and meter tube * 1; The stirring shaft adopts a sealing method without mechanical seal to prevent the contamination of the culture medium by worn carbon powder;

(11) Workstation computer (optional): using Dell high-quality workstation computer, CPU: Intel W-2225 and above (Intel 12th generation and above), memory 16GB and above, hard drive 256SSD+2T and above, 22 inch monitor and above, Windows 10 Professional system.
