Title : Milling and Physio-chemical characteristics of Boro rice Material Type: printed text Authors: Bhandari, Ramesh C. ; Bhurer, K.P., Author ; Roman Karki, Author Pagination: 209-214 p. Languages : English (eng) Keywords: Husk content ; polishing milling recovery gel consistency amylose Abstract: Twenty-one boro (winter) rice cultivars received from RARS, Parwanipur were tested as the
grain quality characteristics. Physical measurements of rough rice and brown rice, milling _
recovery and physico-chemical characteristics were analysed and discussed. The thousandkernel
weight ofrough rice rangedfrom 20.83 to 28.86 gram .The size and shape for husked
rice ranged from 4. 7 to 6.8 mm and 1.95 to 2.93 respectively. The husk content ranged from
18.5 to 25.5 percentage. Husked rice were polished and the calculated amount of polished
rice based on rough rice weight ranged from 63.0 to71.8 percentage. The removal of bran
during polishing ofrice depends upon the softness of the brown rice, which rangedfrom7.3
to 15.5 percentage. The percentage of polished rice calculated at constant 7% polishing
ranged from 69.3 to 75.8. The percentage of amylose content, ranged from 13.3 to 29.4,
analysed by the simplified hand method. The alkali test values ranged from 2 to 7 for
spreading and 1 to 5.5 for clearing. By the gel consistency method, the length ranged from
40 to I 00 mm. The percentage of protein and ash content in brown rice ranged from 6.1 to
8.9 and 1.99 to 1.1 respectively. Among the evaluated cultivars Saroj showed as long and
slender cultivars. The lowest husk content, highest milling recovery at 7% polishing and
good amount of head rice found in NR-10285. The same genotype showed lowest amylose
content. The evaluated cultivars showed which encompassed from hard, medium and soft.

Title : Effect of drying and milling on yield of head rice in paddy Material Type: printed text Authors: M. J. Thapa, Author ; M. B. Shrestha, Author ; Karki R, Author ; Bhandari, R.C., Author Pagination: 20-23 p. Languages : English (eng) Keywords: Rice milling, head rice percentage, milling recovery, methods Abstract: Paddy varieties were dried by three drying treatments sun, shade and oven, and milled by four mills Satake sheller with Yamamoto polisher, Otake sheller with Yamamoto polisher, commercial sheller and traditional huller. Khumal-11 had significantly higher values (P > 0.05) of milling recovery (73.33%) than other varieties. Out of three drying treatments, there was no significant differences in milling recovery but highest value was found in sun drying (69.13%) and lowest in oven drying (68.35%)…………..

Title : Minimization of broken ratio in sequent process of rice shelling and milling. Material Type: printed text Authors: Bhandari, R.C. ; Mahendra J. Thapa, Author ; Man B. Shrestha ; Eiji Bekki, Author Publisher: Khumaltar : Food Research Unit Publication Date: 2004 Pagination: 1-18 .p Keywords: Post harvest technology; Rice; Foods;Sheller, Polisher, Crack ratio, Broken Polishing, Milling recovery Abstract: Shelling and milling experiments were carried out with nine combinations of three types(Rubber-rolls, Centrifugal impeller and Rubber and Steel-rolls) test sheller and two types(Frictional and Emery abrasive) test whitener and polisher in 28 varieties of paddycollected from Terai Plane, Mid-hill, and High-hill (mountain) respectively. From theresults, it was found that there were striking differences in broken ratio among thesevarieties. The fact obtained is considered as one of necessary references when a newvariety will be adopted or accepted in near future. The variety, which is easy to causebreakage, should be avoid to release and take care never to mix with another variety. Thewhole grains having the crack since beginning of harvest will cause broken after shellingand subsequent milling. Long size-slender shaped grain had higher crack ratio than theshort size-bold shaped grain before shelling. Accordingly, the shelling and millinginstruments should be selected and combined with such a type as makes suitable for grainsize-shape. The appropriate grain moisture for shelling and milling is under 14%. Over - dry grain cause formation of cracking in a sound grain A rubber-rolls type sheller(Satake)showed the lowest broken ratio after shelling, however, final broken ratio aftersubsequent milling changed to the highest broken ratio only in milling irrespective ofusing any milling instruments. A centrifugal impeller type sheller(Ohtake) showed thehighest broken ratio after shelling and final broken ratio changed to the lowest one only inmilling. The proportion of each broken occurrence was proved to differ from the shellertype in sequent shelling and milling. The broken ratio, which occurred respectively in either shelling or milling, balanced rather on the shelling side. The entire broken ratio of sequent shelling and milling in the use of a Satake sheller was a little lower than that of Ohtake sheller . Regarding the dehusking efficiencies of three type shellers, average valuesin all the experiments for 28 varieties were within the range from 82.2 to 98%.These range were within the exceeding objective 80% in the laboratory and 98% in actual industrial mills. The lowest milling broken ratio was found in emery abrasive type whitener (Indosaw) among the polisher or whitener used, indicating their gentle milling action. However, this whitener exhibited non uniform whitening and resulted poor appearance of rough grain surface. A frictional type polisher (Yamamoto) exhibited the shinier appearance of polished grain surface, although, higher broken ratio after milling reduced the head rice yield substantially. Milled rice recovery obtained was around 70% as against 70 to 75% of most modem rice mill.
