Description 658-667
The present research was done for the selected minor millets viz. barnyard (Echinola esculenta), Kodo (Paspalum
scrobiculatum), and little millets (Panicum sumatrense). The physical and engineering properties were evaluated at a
moisture content of 10–11%, (dry basis) for whole and hulled millets. Significant improvement in the physical properties of
the millets was observed for the hulled millets. The hulled millets showed higher sphericity (0.68–0.86) and exhibited a
decrease in whole grains' spatial dimensions. The analysis (Gravimetric properties, frictional properties, Aerodynamic
properties) was conducted for both whole and hulled millets. In frictional properties, mild steel surface showed the highest
angle of static friction (9.78–17.96°) with smooth-rolling. The hulling has shown an improvement in all the physical and
engineering properties of millets. In the color values, the whiteness index was improved for hulled millets. In the mechanical
property of grains, resistance to crushing was expressed in terms of hardness.
