Experiment Title Design and Development of Tender Green Sweet Sorghum Grain (Paunk) Roasting machine.
Research Type -
Experiment Background Sorghum (Sorghum bicolor L. Moench) is the most important food, fodder and industrial crop of dry land as well as poor soil agriculture. In the world, sorghum is cultivated over 43.93 million hectares in 98 countries with an average yield of 1.4 MT/ha. Among the cereals in India, sorghum ranks third, next to rice and wheat with area under this crop 6.08 million hectares and 0.70 MT/ha of productivity during 2015-16 (USDA, March, 2018). Maharashtra, Karnataka, Andhra Pradesh, Gujarat, Tamilnadu and Madhya Pradesh are the major sorghum growing states. In Gujarat, it occupied an area of about 1.03 lakh hectares with a productivity of 1340 kg/ha during 2015-16 (www.indiastate.com). The sweet and tender green seed of sorghum at soft dough stage i.e. before physical maturity are known as Pauk or Hurda. The reported ‘Hurda (Pauk)’ purpose sorghum varieties are Wani, PKV Ashwini, Phule Amruta, SGS 8-4 and Sakkari Mukkari Jola under AICSIP. (Patil, et al., 2013). The sorghum is planted normally in the month of July-October and harvested during January-March (Madhusudhan, et al., 2017). The cleaned tender green sweet sorghum seed are used to consume in various way in Gujarat, Rajasthan and Maharashtra (Patil, et al., 2013 and Chavan, et al., 2013). Small and marginal farmers as well as small to medium entrepreneurs are involved in Pauk processing during winter season. One can find, Pauk processing hunts at high way or road side particularly between Bharuch to Dangs district of Gujarat. These Pauk processing hunts are known as Pauk centers. Tender grains are being roasted in hot sand grit and generate tedious environment so it is necessary to develop roasting machine with following objectives.
