Illuminated fermenter (50L)

Ⅰ.Tank body and functions

• Nominal volume: 50 L, optimized diameter-to-height ratio design, and the liquid loading coefficient meets conventional fermentation processes
• Material Structure: The parts in contact with materials are made of 316L stainless steel, the jacket is made of 304 stainless steel, there are no dead corners inside the tank, and it complies with GMP standards.
• Configuration: Large-view sight glass, safety indicator light, integrated standard interfaces fortemperature/pH/DO/defoaming/feeding/exhaust, and sanitary diaphragm valves
• Bottom of the tank: Arc-shaped design without liquid accumulation, enabling in-place high-pressure steam sterilization
• Sampling: Sterile diaphragm sampling valve, no dead ends for sterilization
• Pressure: The tank and jacket are designed for safe pressure bearing, and the inner surface is mirror-polished to hygienic grade precision.
• Sterilization: In-place steam sterilization with adjustable temperature, allowing agitation during sterilization, and easy operation.
• Inoculation: Aseptic inoculation using alcohol flame

Ⅱ.Core System Parameters

Stirring System: Top-mounted mechanical stirring with multi-layer combined impellers and mechanical defoaming impellers; infinitely adjustable speed across a wide range, ensuring stable and precise operation.
PH Control System: Imported high-temperature resistant and sterilizable electrode, intelligent PID automatic acid-base control, broad measurement and control range, high accuracy, and support for automatic calibration.
DO Control System: Imported optical dissolved oxygen electrode, high-temperature resistant and repeatedly sterilizable, with PID intelligent linkage control for stable and adjustable dissolved oxygen.
Lighting System (Optional): Built-in LED light source with manually adjustable light intensity to meet the needs of photosynthetic culture.
Temperature Control System: High-precision sensor with external circulating water bath temperature control, equipped with multiple safety protections for accurate and efficient temperature control.
Defoaming System: Automatic electrode detection, dual mechanical and chemical defoaming, peristaltic pump for automatic defoamer addition with adjustable sensitivity.
Feeding System: Branded peristaltic pump supporting manual/auto modes, cumulative metering of feeding volume, and equipped with sanitary-grade pipeline components.
Aeration System: High-flow configuration with high-precision sterilization filtration, uniform gas distribution, and anti-backflow protection.
Tank Pressure & Pipelines: Real-time pressure gauge display; all pipeline valves are made of 316L sanitary-grade material, resistant to high temperatures and corrosion. 

Ⅲ.Intelligent control system

• It is controlled by Siemens PLC/DCS, with a 10-inch touch screen and a full Chinese interface, and can be connected to a computer for data uploading.
• Real-time monitoring and control of parameters such as temperature, rotating speed, pH, DO, defoaming and ventilation
• Supports multiple control modes: manual / automatic / program segment / remote / linkage
• Data curves, historical records, USB flash drive export to Excel, multi-level password protection
• It can be extended with advanced functions such as exhaust gas analysis, metabolic parameter measurement, and online monitoring.
• Supports independent synchronous control of multiple tanks, with modular independence and convenient maintenance
