【 摘 要 】

The recent upsurge of interest in the demand for oils from soybean has prompted the development of more efficient mechanical screw press. The performance evaluation test was conducted to investigate the expelling efficiency of the machine, the effect of kneading temperature on the oil yield and the extraction losses of the machine. The literature put soybean oil content as between 18-20% of the whole soybean. The moisture content of the soybean used for the experiment was 10.7% (w.b). The mean oil yield, expelling efficiency and extraction losses ranged between 6.61 and 14.22%, 32.26±0.39% (50 oC) and 68.13±2.27% (90 oC), and 5.39% and 9.90% respectively. The optimum kneading temperature that corresponded to the highest expelling efficiency was (69.13±2.27%) at 90 oC. The differences among the mass flow rate values of the paste at the different temperature levels were statistically different (P
