A set of conjoined systems composed of multiple fermenters (the same volume or different volumes) can be suitable for parallel orthogonal experiments, providing an optimized approach for process research and shortening the precious time of research. This equipment configures the process The parameter repeatability is good, and the control system and the volume of the fermenter can be combined arbitrarily, which is convenient and flexible.
Nominal volume: 5L, 7L, 10L, 15L, 20L, 30L, 50L, 100L~1000L
Diameter-height ratio: 1:2.5; Filling coefficient: 70%
Tank body: The main material is all stainless steel 316L tank body, and there is no dead angle in the tank; it is equipped with a special sampling and discharging valve for the fermentation tank, and the transplanting pipeline. Using large viewing angle tank liquid level observation mirror, 12V safety sight light, with temperature, PH, DO, defoaming, liquid level interface, inoculation port, feeding port, and multiple spare ports, all welds are firm, neat and beautiful .
Tank body: Design pressure 0.35Mpa Jacket: Design pressure 0.3Mpa, the optimized diversion design is adopted to improve the exchange efficiency and the uniformity of the temperature in the tank
Tank function: John Crane mechanical seal, air inlet sterilization filter, exhaust condenser, air inlet system with air distributor, flame inoculation port (also feeding port and cleaning port), discharge port, sampling port, Feeding port; five electrodes for automatic parameter control are: PH electrode, DO electrode, defoaming electrode, temperature electrode port; four peristaltic pumps in each tank are automatically controlled to supplement acid/alkali/foam enemy/culture agent respectively;
Motor: special AC motor for fermentation tank to ensure that the motor can run in harsh environments;
Ventilation: One-way deep ventilation is adopted, the flow rate of the gas is adjusted according to the process requirements, and the gas is distributed evenly by the air distributor in the tank; The material backflow device ensures safety and greatly prolongs the service life;
Mixing system: Mechanical mixing system, John Crane mechanical seal, Fuji inverter
Stirring form: straight-blade stirring paddle (second level) inclined blade stirring paddle (first-level), mechanical compression defoaming paddle (first-level), four baffle plates;
Fermentation pH control function: intelligent PID control, special Swiss Mettler PH electrode;
Fermentation dissolved oxygen control function: adopt intelligent PID control, special Swiss METTLER DO electrode;
Temperature control: electric heating, water cooling, circulating temperature control by circulating pump, with air self-escape function and water cut-off and over-temperature protection functions, with good heat exchange efficiency; intelligent module control not only ensures the rapidity of temperature control but also achieves energy saving .
Feeding: The perfect feeding system (acid, alkali, foaming enemy, culture medium) can be used for quantitative feeding at regular intervals; the four peristaltic pumps can be separately 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;
LBR-B type or C type control system: 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 tank data, system data Browse and analyze and read the settings. It can control the stirring speed, the temperature of the medium in the tank, the Ph value, and the DO value;
