Development And Performance Evaluation Of A Double-rotor Self-action Cassava Grater

ABSTRACT The modification of a single-rotor cassava grater was undertaken. The singlerotor grater was modified into a double-rotor self-action grater and its performances evaluated by determining its throughput capacity and efficiency. The throughput capacity was determined by grating known quantities of cassava roots in three respective runs and the time taken to grate them measured from a stop watch. The efficiency of the machine was calculated from the quantity of roots grated and quantity of roots not recovered as dough. The percentage improvement of the measured parameters of the improve…
