Abstract
The AMPD oil expeller originally intended for coconut was initially proven that it can be used for Jatropha curcas oil extraction. This study aimed to optimize the performance of the expeller for Jatropha curcas oil extraction. Fifteen experimental runs were conducted using the Design Number 1 Box and Behnken experimental design to determine the effect of percentage of hull retained in the feedstock, heating temperature of the seeds before pressing, and rotational speed of the shaft screw in relation to oil recovery, milling capacity, and power requirement. The response surface regression of Statistical Analysis System (SAS) was used in analyzing the responses at 90% and 95% confidence level. Results showed that the hull content was directly proportional to oil recovery, milling capacity, and power requirement while shaft speed was indirectly proportional to oil recovery. The expeller can work at optimum conditions of 38 rpm shaft speed, 50 °C temperature, and 70% hull retained in the feedstock. A predictor equation was also generated to describe the relationship of the independent variables in relation to the different response variables. A verification run was also conducted to verify the values of the predicted equation. Results showed that there were no variations between the two values at 95% level of confidence.
