“…Furthermore, the local demand for graded quality rice is also increasing, thus making grading of rice a necessity. Classification of a milled rice grain is done based on its length: 1/1 head rice, 7/8 head rice, 6/8 large broken, 5/8 large broken, 4/8 large broken, 3/8 small broken, 2/8 small broken, and 1/8 small broken (Someswararao, Mahato, Namgial, Huda, & Das, ). Since the inspection of rice quality by humans is neither objective nor reliable, automation with the use of machines must be applied for the desirable result (Kaur & Singh, ).…”

The design and construction of a motorized rice grader were undertaken to classify rice grains into the head rice and broken rice. Three (3) screens of decreasing diameters were used inclined at angles ranging from 6, 8, and 16 0 and driven by a 5 hp motor to cause agitation and a pneumatic mechanism for blowing light chaff material. The performance efficiency of the developed machine was evaluated with milled rice at 15% moisture content (wet basis) at different feed gate levels (FGL) (5 to 20 mm). The result indicated decreased grading efficiency (GE) and product purity (PP) with increased FGL, increased throughput capacity (TPC) and tray loss (TL) with increased FGL. The highest GE and PP were 91.67 and 90.97% at 5 mm FGO, while the highest TPC and TL were achieved at 20 mm FGL as 0.08 kg/s and 1.06%, respectively. The feed gate levels (5 to 20 mm) had a significant effect on the performance efficiencies investigated. Practical applicationsAfter rice milling, there are usually broken rice grains in mixture with head rice. The developed motorized rice grader is useful in separating broken rice grains from the milled rice. This machine would help increase the quality of rice produced by the local or commercial processors. In addition, the time and drudgery associated with manual sorting are reduced.
