Abstract: Sorghum (Sorghum bicolor L.) is an important cereal crop for food and fodder of Indian next to rice, wheat and maize. Sorghum has nutritional composition similar to or better than rice and wheat in some aspects. The grains contain high fiber and non-starchy polysaccharides and starch with some unique characteristics. Protein quality and essential amino acid profile of sorghum is better than many of the cereals and millets. Sorghum in general is rich source of fiber and B-complex vitamins (Chavan et al., 2013). Hurda is the name given to tender Jowar - the main staple grain of rural Maharashtra, India. In early January, jowar grain is juicy and very tender. Just the right time to be eaten roasted. It is generally picked from fields and roasted there and then; this young jowar tastes awesome when roasted. The manual extraction that means removing grains with indigenous techniques is very time consuming process. The availability of suitable hurda machine for this crop would eliminate all drudgery and losses of the crops. Efforts were made to optimize the speed of developed hand operated sorghum hurda extraction machine for extraction sorghum hurda grains at Post Harvest Engineering & Technology, Dr. PDKV, Akola. Performance evaluation was carried out and different response parameters viz., extraction efficiency, percent grain loss and percent mechanical damage were studied. The developed machine is quite reliable and feasible for sorghum hurda extraction. The working capacity of the machine was found to be11.65 kg/h. The maximum extraction efficiency was found to be 85.5% for the speed at 75rpm and 16 kg/h feed rate. The total grain loss including mechanically damaged is 17.01% and the particular mechanically damaged grain loss is 1.3% at the 75 rpm and 16 kg/h feed rate.
