Abstract
The industrial ethanol fermentation is subjected to complex factors. The evolving computer surveillance technology can optimize fermentation conditions for maximum yield. This paper describes the implementation of computer control technology in the industrial ethanol fermentation process, along with the process dynamics principle. As for the surveillance system which includes hardware and software, it enables the auto environment control of the fermenter without manual intervention, field data acquisition and treatment on the fermentation with the aid of the computer. Subsequently, it greatly optimizes the productivity of ethanol fermentation. Some factors such as the number and activity of yeast cells in the process, the role of substrates, and the formation amount of ethanol dominate the fermentation process.
