Sweet Sorghum Processing for Bioethanol Made Easy
September 7, 2007| |
Sweet sorghum is one of the alternative sources of bioethanol besides sugar cane and corn. Its high sugar content and seasonal production in the temperate zones of the United States including Oklahoma requires immediate fermentation in a facility that is operated only seasonally. Lee McClune, president of Sorganol Production Co. Inc. proposed a process involving a harvester, large storage bladder for fermentation and a mobile distillation unit for ethanol purification. Hence, newly harvested sweet sorghum can be easily processed to obtain juice from the stalk and fermented in place immediately. Danielle Bellmer, biosystems engineer with the Ohio State University (OSU) Division of Agricultural Sciences and Natural Resources’ Robert M. Kerr Food and Agricultural Products Center on the other hand would be examining technical processing details such as juice extraction efficiency, pH, nutrient adjustment of the juice for fermentation, and various environmental factors.
Bellmer believes that when this in-field processing system becomes successful, sweet sorghum ethanol will be economically viable because transportation costs and capital investments are minimized.
