Automatic Bioreactor(including exhaust gas analysis system)

Diameter-to-height ratio: 1:2.5; Filling factor: 70%

Tank: the main body is made of stainless steel 316L tank, no dead angle in the tank; It is equipped with special sampling and discharging valves for fermentation tanks and seed transfer pipelines. Using a large viewing angle tank liquid level observation glass, 12V safety lamp, with temperature, PH, DO, defoaming, liquid level interface, inoculation port, feeding port, and multiple spare ports, all welds are firm, neat and beautiful.

Tank: design pressure 0.3Mpa Jacket: design pressure 0.3Mpa, using optimized diversion design, improve the exchange efficiency and the uniformity of temperature in the tank

Tank function: John Crane mechanical seal, air intake sterilization filter, exhaust condenser, air intake system with air distributor, flame inoculation port (also feeding port and cleaning port), discharge port, sampling port, feeding port; The five electrodes with automatic control parameters are: PH electrode, DO electrode, defoaming electrode, and temperature electrode mouth; Four peristaltic pumps are automatically controlled to replenish acid/alkali/bubble enemy/culture agent respectively;

Motor: AC motor for fermenter to ensure that the motor can operate in harsh environments;

Ventilation: a deep ventilation is adopted, the rotameter displays, the flow rate of gas is adjusted according to the process requirements, and the air distributor in the tank is evenly distributed; Sterilization filters with an accuracy of 0.2μm (Dominica or Shanghai Yiming) are adopted, and there is an anti-backflow device to ensure safety and greatly extend the service life;

Stirring system: AC motor, Fuji inverter, using direct coupling mechanical stirring with upper drive or indirect coupling mechanical stirring with lower drive magnetic, simple structure and stable operation

Mixing form: straight blade stirring paddle (second stage), inclined blade stirring paddle (first stage), mechanical compression defoaming paddle (first stage), four material baffle plates;

Fermentation pH control function: intelligent PID control, dedicated Swiss METTLER PH electrode;

Fermentation dissolved oxygen degree control function: intelligent PID control, dedicated Swiss METTLER DO electrode;

Temperature control: electric heating, water cooling, circulating pump circulating temperature control, air self-escape function and water cut-off, over-temperature protection function, with good heat exchange efficiency; The intelligent module control not only ensures the speed of temperature control, but also realizes energy saving.

Feeding: perfect feeding system (acid, alkali, bubble enemy, culture agent), can be regularly and quantitatively fed; Each of the four peristaltic pumps can be set in sections on the control interface, which is convenient and flexible in actual use. Equipped with specially designed feeding pins to ensure the safe operation of feeding;

Automatic sterilization system (optional): BLBIO-SIP automatic sterilization system is a patented product researched and developed on the basis of European fermentation tanks, one-key operation, simple and convenient operation, and simple labor intensity of the operator

BLBIO-type A, B, C, D type control system optional: German Siemens S7-200 series PLC control system + 10" LCD touch screen display operation, on-site direct operation (menu type), full Chinese menu and interface; Sampling and display of tank data, browsing and analysis of system data, reading settings. It can control the stirring speed, the temperature of the medium in the tank, the pH value, and the DO value;

It can set the upper and lower limits of temperature, speed, PH value, DO value, and has the function of over-limit alarm;

It has the functions of over-level alarm and automatic refill, over-level alarm and automatic addition of defoamer;

All alarm accidents can be recorded and consulted;

Speed, temperature, PH value, DO value, etc. can be set to automatic and off state;

Parameters such as medium temperature, stirring speed, Ph, DO and other parameters in the tank can be set and controlled in sections according to the process requirements;

Each parameter has PID adjustment process display, such as set value, real-time value, PID set value, upper and lower limit value, curve display, manual/automatic switching, online setting, etc.;

The historical data and curves of various parameters can be stored for many years, and the real-time curves can be restored as they are when the power is turned on again;

The man-machine interface is friendly, and more than a dozen monitoring screens can be switched;

It has the function of feeding and metering; Regular and quantitative feeding;

The system has a variety of correlation controls: correlation control between velocity and dissolved oxygen, correlation control between feeding and dissolved oxygen, correlation control between feeding and pH value, etc.;

The system has real-time display, data recording and data analysis of the running process

The parameters of each detection and control loop can be manually set and corrected online on the screen, and the temperature, DO, PH sensors can be set and adjusted, and the flow rate of each peristaltic pump can be calibrated. The operation has a password protection function, and the password is divided into operator and administrator-level passwords;

Automatically record the fermenter start-up time, shutdown time, number of power outages during automatic operation, power outage time, call time, etc.;

The software system has self-adaptive and self-diagnostic capabilities;
