Following our country's entry into World Trade Organization (WTO) it has made a strong impact on our traditional agriculture. To be competitive efficient we must improve our agricultural methods and utilize news, efficient automated machinery. At the present time millet threshing is almost all carried out manually requiring lot of energy and very time consuming. Therefore the total annual planting area is falling yearly. A study project into the development of a threshing machine for millet is important for the future production of this corp. The device developed and contracted consists of a threshing cylinder with threshing teeth, concave screen, a winnower, motor drive and straw/grain separation and sieve parts etc. The machine's operation covers threshing separation and cleaning -a complete operation. This machine completely automates the traditional methods of first manually threshing then manually separation. From the experimental results achieved the machine had a threshing rate of over 95% with No grain damage. The operating efficiency was 6 times faster than manual threshing. As training extension program is necessary to promote these improvements to the hard working Taiwan farmers.
