Paddy rice Parboiling is a major processing operation in rice processing. In this study, the effects of steeping temperature and time on the parboiling efficiency and the milling quality of the parboiled paddy rice was determined in the department of agricultural and bio-environmental engineering department was evaluated. During the investigation, the experiment was considered as a 4×3×3 factorial design, with four levels of steeping temperature (60, 65, 70 and 75°C), three levels of steeping time (2, 3 and 4 hours) and three replications in a Randomized Complete Block Design (RCBD) with steeping time as the blocking factor in order to determine the parboiling efficiency of the machine and milling quality of the parboiled rice grains. The optimum parboiling efficiency of 99.7% and corresponding milling quality of 98.5% was obtained at 70°C steeping temperature and 3hours steeping time. The data obtained was statically analyzed using SPSS 21.0 software and the result of the analysis shows that the steeping temperature and time has a significant effect on the parboiling efficiency of the machine and the milling quality of the rice grains at 5% confidence level.
