fermenters & fermentors

2 set of fermenters are controlled by one controller,apply to parallel study; usage in bacteria fermenter.

Specification: 5L-20000L

this picture is three 50L sets of seed fermentor with one 250L main fermentor. it also can be same volume of each fermentor on one platform. each fermentor can work indepently or together.Pressure: 0.1Mpa-0.6MpaRotate speed: 50-400rpm for research scale, pilot scale, 50-200 for industrial scaleMaterial: Contacting parts is made by SS316L, other parts is made by SS304Agitator type: Mechanical agitator Surface finishes: Inside surface Ra0.28μ um - 0.4μ m by mechanical polishing or electropolishingOutside surface Ra0.4μ um - 0.6μ m by satin finishing Feature: Fermentor is simens' PLC control system, and this system adopts simens' human-machine interface(HMI) and PID control, which can measure and automatically control parameters of temperature, rpm, pH, DO, feed, foam and etc. It possesses functions of digital setting, quick validation, data display, data storage, data print, password management and so on. It has commucation connection which can communicate with computer.

Struction: two fermentor vessels  with one control system.

This series of tank are made of many fermentors, and installed on one platform with one control panel. each tank can work independently and together at same time. small seed tank can inoculate to the main fermentor
