Abstract

The study aimed to evaluate the performance of a single effect evaporator system to produce 60°brix sweet sorghum syrup for bioethanol production. The performance was tested by varying the flowrate of the feed, temperature of the steam and installation of a vacuum pump. It is evaluated by calculating the steam economy, heat transfer efficiency, and overall heat transfer coefficient. Their effect on the characteristics of the steam and vapor produced were also determined. Modifications in the feed tank were made to continuously operate the system and successfully produce 60°brix syrup. The evaporation time, the time by which the syrup reached 60°brix decreases as the feed flowrate and steam temperature increases. It was also observed that as the flowrate of the feed increases, the steam economy, heat transfer efficiency, and overall heat transfer coefficient also increases. Relatively, vacuum pump installation in the system lessen the total power needed to produce 60°brix syrup.
