Peanut hull (waste material from processing of peanuts) has been identified as a potential biofuel feedstock in the Southeastern part of United States. To improve the handling and storage characteristics of peanut hull, they were pelleted through a 3/16-in (4.76 mm) diameter die. The physical properties of the pellets were measured within a moisture range of 4.2 and 21.2% (w.b.). Pelleting increased the bulk density of the peanut hull from 151 kg/m3 to more than 600 kg/m3 . Bulk density, particle density and durability of the pelleted peanut hull were significantly affected by moisture content. Air relative humidity significantly influenced the rate at which the pellets exchange moisture with the environment while air temperature did not. The values of the constants of the GAB model were obtained from moisture sorption isotherm at 25C.(Download PDF) (Export to EndNotes)
