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-0.6Mpa Rotate speed: 50-400rpm for research scale, pilot scale, 50-200 for industrial scale Material: Contacting parts is made by SS316L, other parts is made by SS304 Agitator type: Mechanical agitator Surface finishes: Inside surface Ra0.28μ um - 0.4μ m by mechanical polishing or electropolishing Outside 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: many 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 togetherat same time. small seed tank can inoculate to the main fermentor Control parts for fermentor No. Parameter name Technical indicator 1 PH 1.On-line check and measure, and digitization fully automatic control; 2.PH, acid and base gang control.
