This page gives the schedule used in the PlantOps360 task library for oilseed expeller (, solvent extraction plant and edible oil refinery), which follows common industry practice for general-purpose equipment. It is also searched for as oil expeller, solvent extraction, oil refinery edible, degumming.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
