Stainless Steel Fermenter

SUS 316 material tank body SUS304 jacket, stainless steel 316L tank cover, easy to observe the material; 

with temperature, pH, DO, defoaming, liquid level interface, inoculation port, feeding port;

The design pressure: P(inside)= 0.3Mpa, P(interlayer)=0.3Mpa, The polishing precision: 

Ra0.4~0.6,the ratio between diameter and height: 1:2.5

In situ steam automatic /manual sterilization, sterilization temperature 100-130℃,

Sterilization can be stirred at the same time, can thoroughly sterilize the medium.

Configure one air intake (air) including: rotameter, mass flowmeter,  2-stage sterilization filter, 

non-return valve, etc., to ensure that the air enters the tank aseptically.

Using an aerator (Ring Sparger & Microsparger) and Overlay to supply gases simultaneously 

Two-way ventilation is equipped with four-way gas (Air, O2, CO2, N2) mixed intake, 

mass flow meter (four-way TMFC automatic adjustment) to be able to supply different gas mixtures in 

these ways.

Mechanical sealing or Magnetic coupling stirring at the top of the fermenter;

Fermentation special blades, stirring form: 4x baffles. 1x comb type foam breaker., 

also according to fermentation the special requirements of the process are to replace different 

types of stirring paddles.

Heat by thermostatic water tank and circulate by circulating pump,

Temperature control: ambient +5℃-65℃;±0.1℃, display temperature: 0-150℃±0.1℃

Automatic or manual adjustment, flow meter display; 

range:0.1-2.0vvm; 

Automatically check foam, automatically add antifoam by

peristaltic pump.

Control by peristaltic pump switch, automatically feeding and

computation.

Using intelligent PID control, high control accuracy, and it is not easy to fluctuate, peristaltic pump 

switch to control the flow of acid and alkali, automatic control, automatic measurement. 

The electrode can be sterilized repeatedly, and  the calibration function is completely calibrated by the 

system software.

The DO value is controlled in association with the speed,replenishment, air flow (if configured) 

and other parameters.

Control range: 0~150%, ±3% fermentation process sequence control (according to fermentation 

time, DO automatic variable control, at least 10 stages)

Control parameter: temp, pH, DO, antifoam, stirrer rev, feeding,etc

BioVita S is an on-site controller designed for Siemens S7-1200 series PLC, offering a stable and versatile 

solution for automation, especially in manufacturing process control. Its modular design enables easy

implementation of distributed configurations. The system features a 12-inch LCD touchscreen

with an intuitive English menu, supporting direct on-site operation and data transmission 

to a host computer for analysis.   

Control Modes:

      - Correlation: DO control via   speed, airflow, pressure, 

feeding; pH control via acid/alkali 

Measurement Functions:

     -Supports pH, feeding, and anti-foam monitoring 

      - Independent module-based parameter transmission for 

easy maintenance   

Real-time Monitoring: 

     -Displays system status, hardware conditions, and fault identification for pumps, 

heating, mixing, etc. 

The system integrates Siemens S7 software and FORCE CONTROL, utilizing Siemens S1200 PLC 

for data collection and control. It ensures high precision, adaptability to various sensors, 

and robust anti-interference capabilities.
