Abstract

The fifth-most important cereal in the world is sorghum, which is widely cultivated for human consumption and for use in animal feed. Physical characteristics like size, shape, surface area, volume, density, porosity, colour, and appearance are crucial when designing a specific piece of machinery or figuring out how a product will behave during handling. Standard methods were used to determine the physical properties of sorghum grains. In this study, the average value of sorghum grain dimension was determined at various moisture contents. At 12%, 14%, 16%, 18%, and 20% moisture content, the 1000 grain weight was found to be 39.52 g (±1 g), 47.92 g (±1 g), 52.76 g (±1 g), 61.06 g (±1 g), and 67.26 g (±1 g), respectively. The length (4.30), width (3.87) and thickness (2.74) of the soaked sorghum were linearly increased according to moisture content. The equivalent diameter (4.44), square mean diameter (6.17), arithmetic mean diameter (3.62), geometric mean diameter (3.57), degree of sphericity (0.84), aspect ratio (0.89), and shape factor (4.22) of soaked sorghum all increased with moisture content. The variation of bulk density and true density of sorghum grain with moisture level. The bulk density of sorghum grain decreased linearly from 824 to 801 kg/mm3. The true density of sorghum grain decreased linearly from 1560 to 1370 kg/mm3, respectively. Basic information on these engineering properties is of great importance and help engineers towards efficient process and equipment development.

Conclusion

1. The engineering properties of sorghum were measured at 12 to 20% (w.b.) moisture content. 2. At 12%, 14%, 16%, 18%, and 20% moisture content, the 1000 grain weight was found to be 39.52 g (±1 g), 47.92 g (±1 g), 52.76 g (±1 g), 61.06 g (±1 g), and 67.26 g (±1 g), respectively. 3. The length (4.30), width (3.87) and thickness (2.74) of the soaked sorghum were linearly increased. 4. The arithmetic mean diameter (3.62), geometric mean diameter (3.57), square mean diameter (6.17), equivalent diameter (4.44), degree of sphericity (0.84), aspect ratio (0.89), and shape factor (4.22), of soaked sorghum were increased as increased moisture content. 5. The variation of bulk density and true density of sorghum grain with moisture level. The bulk density of sorghum grain decreased linearly from 824 to 801 kg/mm3. The true density of sorghum grain decreased linearly from 1560 to 1370 kg/mm3, respectively.
