The LBR-XSJA-AUTO series automatic bioreactor is a 316L stainless steel tank with no dead ends and a spherical tank bottom head, which can obtain better fluid performance and the best mixing effect. The long glass sight glass is easy to observe the state of the tank, and the sight glass lamp is specially designed for quick interface, which is convenient and safe to operate. Standard pH, DO, and temperature interfaces are reserved, aseptic sampling and discharge ports are designed with multi-valve combination, and the tank top includes an inoculation port, a feeding port, a foam electrode port, an exhaust condenser port, and multiple spare ports. The pipeline valves are all made of stainless steel, special sanitary pipeline valves for food and fermentation, under the premise of achieving complete functions, simplify the pipeline design, reduce the chance of contamination, the structure is reasonable, and the appearance is elegant;
Stirring method: direct-drive mechanical stirring or magnetic driving mechanical stirring method, stepless speed regulation, can run stably at lower and higher speeds, no idling or slipping, and accurate speed measurement. The standard stirring paddle adopts closed six flat blades, and there are many other types of propellers to choose from, such as oblique blade propellers, turboprops, arrow blades, screw ribbon propellers, open six flat blades, etc. The position of the stirring paddle is adjustable, and it can also be freely combined with other paddle types to obtain the best fluid type. Reasonable baffle design can effectively eliminate the vortex generated during stirring, and obtain a higher secondary flow, which greatly improves the heat and mass transfer rate.

LBR-SIP tank automatic sterilization system: a patented product researched and developed on the basis of European fermentation tanks, one-key operation, reducing the labor intensity of the operator;
LBR-CIP tank automatic cleaning system (optional): The tank is cleaned by the automatic system to reduce labor intensity;
LBR-C type control system: industrial control computer + Siemens S7-200 series PLC control system, it is a mature, stable and general-purpose PLC, which can be suitable for various applications of automation, and is suitable for process control in manufacturing process control. Research. Its modularization, easy to realize distributed configuration and easy to master, etc., Siemens PLC control core has become an economical and advanced control system in the implementation of biological reaction process control. The system uses a tablet computer of more than 10 inches to control 8 direct parameters such as pH, DO, tank pressure, temperature, speed, air flow, defoaming, and feeding, as well as automatic sterilization of tank pipes, automatic tank cleaning, and automatic lifting of tank covers. process and can calculate indirect parameters.
The pH and DO electrodes can be easily calibrated through the software; the initial control state of the parameters is set
