The single screw oil press


It was a portable oil-press described by Heron of Alexandria which continues to be in extensive use in various forms until today.

It consisted of a powerful rectangular frame and an endless screw that could be turned with the help of handles inside a special receptor (female screw type) in the upper horizontal beam of the frame. With its rotation, the endless screw pushed a horizontal wooden plank which in turn pressed the olive pulp (which was inside a special holding ring system) so that it discharged the olive oil.
