Moisture sorption characteristics and modeling of energy sorghum (Sorghum bicolor (L.) Moench)

► Equilibrium moisture content is influenced by temperature and sorption direction. ► Safe aerobic storage moisture levels range from 12.0% to 18.4% dry basis. ► Desorption surface moisture becomes material-bound by approximately 25% dry basis. ► Material swelling at low moisture causes an increase in moisture sorption sites.
