The relationships among speeds of screw press, compression distances and types of rice bran were studied for optimal condition of cold press oil extraction of rice bran. Results of the study showed that the compression distance of 1.7 and 1.3 cm at the screw speed of 8.4 rpm were the optimal condition for providing the highest yielding of 4.17 and 8.2% oil extraction for raw rice bran and parboiled rice bran, respectively. The texture and discharge pattern of the pressed cake is a reliable guide to predict the oil content in the pressed cake.
