“…The frictional properties like angle of repose and coefficient of friction helps the engineers in designing of storage bins, godowns etc. The mean result for the angle of repose was 27°47'± 0.21 is comparable with the angle of repose (27-32°8') reported for the finger millet, kodo millet and little millet (Shivabasappa et al, 2012;Balasubramanian, 2016;Dewendra Kumar et al, 2016) [23,5,9] . The coefficient of friction for the three surfaces namely, Glass, Aluminum and Wooden Sheets were 0.62 ± 0.0009, 0.59 ± 0.0051 and 0.6 ± 0.0063, respectively (Table 3).…”

Browntop millet (Urochloa ramose L.) known as 'korale' in Karnataka is an annual warm-season grass often used as a forage crop gaining importance because of its nutritional qualities. Very fewer researches have been done so far on the millet. The research was conducted to determine the physical properties of the browntop millet. The physical properties were determined at moisture content 11.2 ± 0.16 (w.b). The mean values of length, width and thickness of the browntop millet were found to be 3.00 ± 0.21, 1.79 ± 0.10 and 1.15 ± 0.09 mm, respectively. The geometric mean diameter and arithmetic mean diameter were 1.82 ± 0.09 and 1.99 ± 0.1 mm, respectively. The mean weight of 1000 browntop millet seeds was 3.42 ± 0.14 g. The bulk density and true density were 601.17 ± 4.08 and 1305.47±95.5 kg/m 3 , respectively. The mean porosity, aspect ratio and sphericity were found to be 53.74 ± 3.23, 58.58 ± 3.84 and 59.82 ± 2.60%, respectively. The shape of the browntop millet was oval. The angle of repose was 27°47' ± 0.21 and the coefficient of friction for the three surfaces namely, Glass, Aluminum and Wooden Sheets were 0.62 ± 0.0009, 0.59 ± 0.0051 and 0.6 ± 0.0063, respectively. The terminal velocity was 7.2 m/sec. The tristimulous colour values (L*, a* and b*) were found to be 60.45 ± 0.44, 3.78 ± 0.06 and 14.71 ± 0.33, respectively. Hence this study helps agricultural and food engineers, designers, scientists and processors towards design of equipment and efficient process for browntop millet grain processing.

“…The results obtained for bulk density, true density, angle of repose and porosity were close to the findings of (Sunil, Venkatachalapathy et al, 2016) [22] . The co-efficient of friction against the mild steel was 0.781 and these result was closer to the value obtained by (Chandan Kumar V.b 2018) [6] .…”

Hermetic storage is sealed airtight non-chemical based storage system used to preserve the quality of grain, protect from pests, insects, and minimizes the storage losses. A hermetic storage bin was designed with a capacity 200 kg for de-hulled kodo millet. To design the hermetic bin the physical properties of de-hulled kodo millet such as bulk density, true density, porosity, angle of repose and co-efficient of friction were studied. The bulk density, true density, porosity, and angle of repose of de-hulled kodo millet were found to be 685.42 kg/m 3 , 1250 kg/m 3 , 45.16% and 26.1°. The co-efficient of friction of dehulled kodo millet against the mild steel was found to be 0.781. The lateral pressure exerted on the wall surface for was 123.45 kg/m 3 at the height of 0.6m. Pressure decay test was performed to check the air tightness of the hermetic bin. This hermetic bin can advocated to farmers and processors for value addition of small millets.

“…Grains with higher sphericity and size, yield more head grains. From the studies by Kumar et al (2016) and Nagaraju et al (2020), kodo millet has higher sphericity and larger size than browntop millet. The findings of the current study are in acceptance with the previous reports since the head grain yield of kodo millet is comparatively higher than that of browntop millet at similar levels of polishing.…”

Millets are termed ‘Nutri‐cereals’ as they possess exceptional nutrition profiles. They undergo several processing operations from farm to fork. Polishing is one of the important primary processing operations of millets that facilitates de‐branning. The current work aims to investigate the effect of polishing process parameters like grain's initial moisture content, the rotational speed of polisher, polishing time, on milling yield, nutritional losses of kodo, and browntop millets; to optimize the polishing process through response surface methodology. The polisher speed was found to influence milling and nutritional properties in both the millets whereas, the effect of grain's initial moisture was mostly observed in some responses of browntop millet. Kodo millet polishing at 10% initial moisture content, 1900 rpm for 2 min, and browntop millet polishing at 10% initial moisture content, 1300 rpm for 8 min were obtained as optimum polishing conditions. The degree of polishing and head grain yield at optimum conditions were in the range of 3.5%–4.0%, and 84%–92%, respectively. Less than 15% of nutritional losses were observed at optimum polishing conditions.Practical applicationsIndiscriminate polishing of millets has become most common industrial practice resulting in less head yield and high nutritional losses. Form the current study, both food processors and researchers get a brief knowledge on the effect of every polishing parameter such as grain moisture content before polishing, rotational speed of abrasive roller in polisher, time of polishing on milling losses and proximate compositions. The optimized process parameters can be directly employed in industrial polishing applications to produce polished grains with higher head yield and very minimal nutritional losses.
