Abstract

A locally developed grain milling machine was evaluated using maize (Sammaz - 12 variety) and millet (Lake Chad Dwarf variety) at different moisture range of 8.3% to 24.6% and 6.4% to 27.2% (db) respectively. The performance indices considered for the evaluation of the machine were milling efficiency, machine efficiency and milling rate. The results obtained were subjected to statistical analysis. The results showed that all the parameters evaluated decreased with increase in moisture content for both grains used in testing evaluating the performance of the machine. It was found that, the milling efficiency and milling rate decreased from 86.3% to 40%  and 20.4 to 12.5kg/h for maize respectively and 89% to 26.6% and 23.4kg/h to 12.1kg/h for millet respectively as the moisture content was increased. Statistical analysis showed significant (P < 0.05) differences between the crop moisture content and milling efficiency and machine efficiency. The milling rate was not significantly affected by the moisture content for both grains used in the study.
