A study and Test of Washing Peeling Cassava Root from the Production of Cassava Starch for used as a Binder for Charcoal

Abstract

This research aims to study and test the washing peeling cassava root in the production of cassava starch used as a binder for charcoal. When the peel - meat was ground and separated into sizes, with resolution through sieves of decreasing sizes: 0.2-0.1 , 0.1-0.05 and less than 0.05 mm, respectively ,they were tested as binders for charcoal in a ratio of 20 percent by weight of powdered charcoal. It was found that at initial moisture content of charcoal of 28.4% wb. , the heating values were 3,129 , 3,155 and 3,147 Cal/g. respectively, as compared to the tapioca flour heating value of 3,033 Cal/g.  They were also tested for hardness and it was found that the hardness were at 66.59, 70.81 and 62.25 kPa. respectively ,as compared to the tapioca flour hardness of 58.96 kPa. Thus it was considered possible to use the washing peeling cassava root as binder in the production of charcoal.
