Chapter 15 - Computer Applications in Fermentation Technology

Abstract

This chapter discusses the applications of computers in fermentation technology. Computers have a variety of applications in the fermentation industry ranging from data logging and on-line analysis to process modeling, control, and optimization. This is mainly in the areas of data logging and online analysis. With the advent of inexpensive and reliable minicomputers, it has become economical to utilize a computer system online. With this capability, it has been possible to move rapidly to a computer applications level that involves partial process control based upon using predetermined set points for controlling primary fermentation parameters, such as temperature, pH, and dissolved oxygen. It has also been possible to utilize the information generated online to study the process and to elaborate the process kinetics. With the development of more powerful minicomputer operating system software, it is possible to operate the computer system using both foreground/background tasks, that is, simultaneously performing the online data acquisition and analysis tasks, and simultaneously doing online process simulation. Once significant operating confidence is obtained with process kinetic models, computer systems can advance to the final stage of automatic process control.
