CONSTRUCTION DETAILS
TECHNOLOGY
Your pilot fermenter has a dedicated control unit on which are grouped the pumps, mass-flows, and the control screen.
It is made entirely of stainless steel by Bailun Technology in their integrated workshop. This allows us to adapt very quickly to your needs.
The fermenter is equipped with sensors and actuators from mostly Western brands, in order to facilitate its development and maintenance over time in France and Switzerland.
It is mounted on a "skid" at the factory, which is FAT tested before shipment. When it arrives at your site, simply connect it to the utilities to start commissioning.
It is a stable and universal PLC, suitable for a variety of automation applications, especially for manufacturing process control. It is easy to network; it is the control unit of your fermenter.
You can therefore either display on the 10'' touch screen present on the unit all the information present in the software, or on a remote computer (option not encrypted in this offer): transmission of process data, visualization of the process, recorded samples, process parameters, etc...
And also benefit from all the standard peripherals offered by Siemens to integrate your fermenter into an internal industrial network.
The Siemens PLC allows in particular to exchange data in Profinet or in OPC-UA with a SCADA type supervisor.
Control stack: Built on Siemens S7 + FORCE CONTROL for robust, long-term scalability.
Hardware-agnostic: Works with actuators/sensors from multiple brands; easy to evolve as needs change.
Interface: Ergonomic SCADA-style synoptic; software in English (French optional).
Operation modes: Manual or recipe-driven; controls rotameters, pumps, agitation, aeration, heating/cooling from sensor inputs.
Control logic: PID or continuous; cascade strategies supported.
Core features: User/password management, sensor calibration, live synoptic views, alarms, and batch data logging/export.
Automation: Semi-automation via configurable cascading laws.
Your fermenter is fitted with Watson-Marlow peristaltic pumps, selected to match the required flow range for each vessel size. Pumps can run manually or be software-controlled.
Standard setup
4 pumps: acid, base, antifoam, feed.
Expandable
Add channels for online analysis, continuous processing, turbidostat operation, or other process needs.
Standard setup: One rotameter per gas line (air / O₂ / CO₂ / N₂).
MFCs: One or more European-made Mass Flow Controllers—typically Bürkert or Vögtlin—for precise, recipe-driven gas delivery.
Sterility: Gas lines are sterile; filters and valves are in-line sterilizable (SIP).
Control logic: Software supports DO (pO₂)-linked cascades and automatic transitions per your rules.
Aeration rate: vvm (vessel volumes per minute) set to your specification and logged.
Model selection: The exact MFC model is finalized with you after order during the detail-definition phase (same price across options).
Condenser on exhaust: Positioned on the fermenter outlet to manage vapor and protect downstream components.
In-line sterilizable HEPA filter: Exhaust passes through a SIP-capable HEPA filter; integrity is verified in situ.
Software-controlled relief valve: Provides over/under-pressure protection with setpoints managed by the control system.
Hygienic design: Condenser geometry minimizes liquid hold-up and prevents bacterial buildup.
Condensate drain: Dedicated drain valve, manually operated.
Instrument: GXH-3011N by HUAYUN Instruments; multiple versions available to match application needs.
Placement: Enclosed analyzer box mounted next to the fermenter for continuous online exhaust monitoring.
Measurement principle: NDIR (non-dispersive infrared). Selective absorption at specific IR wavelengths; signal is proportional to target-gas concentration.
Supported gases: Continuous measurement of CO, CO₂, CH₄, NO, SO₂, NH₃ (and variants per model).
Use cases: Suitable for industrial process control (petrochemical, chemical, metallurgy) and research settings (agriculture, healthcare, universities).
RQ Measurement (option)
Add RQ analysis software plus a dedicated PC for continuous RQ calculation.
Note: RQ computation runs on the PC, not on the Siemens PLC.
Materials: Product-contact 316L stainless steel tank and lid; 304 stainless steel double jacket; all process piping in 316L.
Sight window: Vertical rectangular viewing window integrated on the tank side.
Jacket rating: Double jacket rated to 3 bar maximum pressure.
Overpressure protection: Fermenter fitted with a safety valve calibrated to your application.
Material: 316L stainless steel.
Standard ports (total: 20):
3 liquid-addition ports
1 motor shaft port
1 inoculation port
1 sterile sampling port
1 harvest/collection port
5 utility/auxiliary connection ports
8 probe/sensor ports
The attached image is illustrative only.

Baffles: 4 removable baffles supplied as standard.
Standard: supplied with a ring sparger.
Options: alternative sparger geometries can be selected during the final specification phase to match your process needs.
Sensor: Pt100 temperature probe.
Heating control: Via the double jacket using an electric resistance in the control unit or a steam valve (model-dependent).
Cooling: By mains water or a recirculating loop using an optional chiller/cryostat.
Control range: From mains water temp +5 °C up to 65 °C, accuracy ±0.2 °C.
Display range: 0–150 °C, resolution/accuracy ±0.1 °C.
Sensor: Swiss-made pO₂ electrode.

Integration: Setpoint, delay, and dosing volume are managed in the control software and logged per batch.
Override: Manual dosing and sensor bypass available from the HMI (for setup or troubleshooting).
