Performance Evaluation of Motorized Millet Thresher

Millets are grown in semi-arid regions of the world which require less water to grow, particularly these crops were grown in Asia and. African continents of the world. Telangana has a semi-arid weather condition which is a suitable environment for the cultivation of millets. Commonly cultivated millets in Telangana are Sorghum, Pearl millet, Finger millet (major millets) Foxtail, little, Kodo, Proso and Barnyard millet (minor millets). A study was conducted to evaluate the performance of CIAE developed motorized thresher. The thresher was evaluated for three millets, Foxtail, Barnyard and Finger millets. The evaluation was conducted by AICRP on Farm Implements and Machinery, PJTAU, Rajendranagar at Regional Agricultural Research Station (RARS), Palem, Nagarkurnool District. Key performance indicators of thresher viz., feed rate, input capacity, output capacity, blower loss, un threshed grain, threshing efficiency and cleaning efficiency were measured. Results indicate that threshing efficiency for Foxtail millet, Finger millet and Barnyard millet are 97.94%, 92.17% and 97.52% respectively. The cleaning efficiency of Foxtail millet, Finger millet and Barnyard millet were 99%, 92.47% and 94.00% respectively.
