Washing olives at a mechanized olive mill in Astrikas village, Crete

Olives enter the olive receiving area on conveyor belts for separation from leaves and branches and then enter the mill. They may be washed either outside or inside the mill. In both traditional and modern mills, olives are ground or crushed into a paste which is pressed or churned to release oil that must then be separated from other liquids and solids.
