Some practical aspects of computer applications in a fermentor hall

Abstract

The use of computers in a fermentation pilot plant is described from a practical point of view. The aim is not the application of a computer to a single special process but a general application of computers to prepare and present data for the following analysis of fermentation processes. The hardware is normally bought from computer manufacturers, but some additional installations are useful. Application software has to be developed by the biotechnologist, therefore the software structure is the most important part of the computer application. Data storage is divided into three parts: short-time memory, long-time storage, and a medium memory mainly to be used in process analyses and process control. Four types of programs are used: main schedule tasks, low-priority on-line tasks, sense-switch routine, and different off-line programs. A table of all programs is presented, the main schedule task is described in detail to demonstrate the software structure.
