Abstract: Ragi (finger millet) is an important cereal and fodder crop which is extensively cultivated in southern Asian countries like India, Malaysia and Nepal and is known for its high drought tolerance and nutritional properties. Thus, there is a requirement of cheap, affordable, easy to maintain and economical ragi processing machine which is designed and aimed specifically towards farmers with medium to small holdings. The design and fabrication of such a machine has been carried out in Vemana Institute of Technology. The machine was being designed to replicate the manual beating method of ragi for threshing. Power was derived from an AC motor and was transmitted to a central shaft carrying the crushers via a V-belt drive. The central shaft is supported via pillow block bearings from the frame. When the central shaft rotates, the crusher arrangement also rotates inside a closed drum, and the unprocessed ragi is threshed on the obstructers, hence separating the seed from its husk
