| Popis: | The performance of a rotary screen cowpea cleaner was evaluated at angles of inclination of 5, 10, 15 and 20o, screen speed of 115, 145 , 200 , 280 and 300 rpm with corresponding air velocity of 0.3, 1.3, 2.2, and 2.7 m/s using two varieties of cowpea namely Ife brown and IT90K-277-2. The results show that for Ife brown the highest cleaning efficiency of 71.12% was obtained at angle of inclination of 5o, screen speed of 315 rpm and air velocity of 3.5 m/s. The highest cleaning efficiency for IT90K-277-2 of 68.89% was also obtained at the same angle of inclination, screen speed and air velocity. Response surface plots for both varieties showed that increase in air velocity produced more increase in the cleaning efficiency than increase in screen speed. Mathematical equations for predicting the cleaning efficiency for both varieties were also determined. Keywords— Rotary screen, cowpea, cleaning efficiency |
