A. Features The size of vessel can be decided upon the working volumes of real media and we provide interchangeable vessels that are convenient to scale up vessel among the various size of vessels such as 1L, 5L, 7L and 10L. This system can be employed for batch fermentation, fed-batch fermentation and continuous fermentation with microprocessor that displays Temp, pH, DO, agitation and peristaltic pumping controls of fermentation procedure on the control panel. Agitation motor speed controlled by Dissolved oxygen rate in the DO mode automatically. Software produces real time data, graphics and also provides data logging function and analysis of every single phase of fermentation process. Computer controls and data control (input and retrieve) : Time length of collecting data is longer than normal data recorder. Data conversion function with excel file and it reads efficient data collection from fermentation process. Reduce monitoring time. pH, DO offset : A operating instant of pH can be setting up by user, which resolve any control problem’s are occurred. User can choose feeding time so as to have stability and controllability. DO value from Dean band lead to certain point of feeding.
