Abstract

RICE BREAKAGE in PADDY MILLING is an important cause of crop loss in Iran. In this regard, an experiment was conducted at the Rice Research Institute of Iran to study the effects of two engineering factors (the rotor speed of RICE JET PEARLER and air flow) and the effects of two varietal factors (kernel shape and inlet grain moisture content) on RICE BREAKAGE. Rotor speed at levels were: 600, 700, 800, 900 rpm and for air flow at two levels: without and with air flow. Three levels of grain moisture content were adapted as: %8-9 , %10-11 and %12-13. Three rice varieties of Khazar (long grain), Binam (medium grain) and Gharib (short grain) were selected for the experiment. Results showed that as rotor speed increased, the amount of RICE BREAKAGE, first decreased and then increased. Breakage of Khazar variety was more than Binam and that of the binam variety was more than Gharib variety. Amount of RICE BREAKAGE increased with increasing moisture content. Introduction of air flow into rice during milling resulted in a significant decrease in kernel breakage. Thus, airflow is an important factor that should be considered in design of frictional whiteners. Results of statistical analysis of the data indicated that the best combination of rotor speed and grain moisture content for all three varieties was 800 rpm and %8-9, respectively. Different regression equations were developed to predict percent breakage of rice, for two conditions (with and without air flow). The best and simplest models were two second order equations having three variables of: pearler rotor rpm, grain moisture content, and kernel slenderness ratio.
