Generally, the recommended pre-pressing operations for oil expression include grinding or flaking and then cooking pre-cleaned oilseeds. The literature indicates that pressure, temperature, pressing time and moisture content are the factors which affect oil yield during expression processing of oilseeds. Nearly all of the yield data reported correspond to hydraulic presses while the current technology, at least in the U.S.A., for expression processing is the screw press. Research is still needed to determine if these factors affect the screw-pressing process in the same way and to the same extent as they do in a static pressing operation.
