Effect of moisture content on physical properties of cassava stalk pellets

Abstract

Cassava stalk residues are abandoned after the harvesting period. One of the possible ways to manage cassava stalk residues is by converting them into biomass energy by pelletization. The pelletization was started with the cassava stalks were milled and sieved to make them uniform. The moisture content was defined as percentage of water adding by mass of raw material. The pelletization was performed using conventional pelletizer. The physical properties of Cassava pellets (particle density, bulk density and porosity) were evaluated. The best condition to pelletize Cassava stalk pellets was at water adding 10% by mass of raw material. The range of pellet’s particle density, bulk density and porosity are between 1062.56 to 1262.57 kg m^-3, 311.89 to 718.18 kg m^-3 and 43.10 % to 70.62 %, respectively.
