Abstract
A theory is proposed of the physics of oil expression in a screw press. Deviation of 16 to 27% between the predicted and experimental values of extrusion pressure and oil flow rate indicate that the theory needs further improvement. The theory, however, provides an alternative to costly and time-consuming empirical studies in obtaining information about the performance of a press.
