The energy consumption for different operative conditions and configurations of the bioethanol production industrial process from an experimental variety of sweet potato (Ipomea batatas) K 9807.1 was evaluated. A process simulation model was developed using SuperPro Designer® software. The model was based on experimental data gathered from our laboratory experiments and technology and equipment suppliers. The effects of the dry matter ratio of sweet potato to water, the fermentation efficiency, and sweet potato sugar content, on the energy consumption (steam and electricity) were respectively evaluated. All factors were significant. The best ratio of dry matter to total water to work with fresh sweet potato was 0.2 kg dry sweet potato/kg water, as for greater ratios was not found a significant reduction in energy consumption. Also, the drying of the sweet potato previous its processing was studied. It presented an energy consumption greater than the energetic content of the bioethanol produced.
评估了从实验品种甘薯（Ipomea batatas）K 9807.1 生产生物乙醇的不同操作条件和配置的能耗。使用 SuperPro Designer®软件开发了过程模拟模型。该模型基于从我们的实验室实验和技术与设备供应商收集的实验数据。分别评估了甘薯与水的干物质比、发酵效率和甘薯中糖含量对能耗（蒸汽和电力）的影响。所有因素都很重要。使用新鲜甘薯的最佳干物质与总水量比为 0.2 kg 干甘薯/kg 水，因为更高的比例并没有发现能耗显著降低。此外，还研究了在加工之前对甘薯进行干燥的情况。它的能耗大于所生产的生物乙醇的能量含量。
