Cassava and corn are the two main ingredients in the process of producing fuel ethanol. This paper is mainly based on experiments. In this experiment, the traditional ethanol fermentation with cassava and corn as raw materials was compared with the the industrial ethanol fermentation with the same raw material, and the technological parameters of ethanol fermentation in traditional ethanol fermentation and industrial ethanol fermentation were compared and studied. The traditional double enzyme method was used for ethanol fermentation. Liquefaction temperature (70 plus or minus 1)°C, Saccharification temperature (60 plus or minus 1)°C, Fermentation temperature (30 plus or minus 1)°C. Experimental results show that: The average alcoholic production rate of corn was 36.64% and the average alcoholic production rate of cassava was 42.46% in the traditional ethanol fermentation, the average alcoholic production rate of corn was 38.22% and the average alcoholic production rate of cassava was 44.76% in the industrial ethanol fermentation. The industrial ethanol fermentation experiment is better than the traditional ethanol fermentation by comparison, because the former has better sealed anaerobic environment and greater capacity. It is suitable for large-scale production parameter study, in order to obtain higher utilization rate of raw materials, it shows a higher rate of alcohol production.
