need help refurbing a old cider press

"drying" is a bit of a confuser -because as you say it does not dry in the sense that it evaporates.
It is more to do with the penetration vs no penetration.
You are correct in that they do not really dry (evaporate) even though they are "drying oils"

Anyway - not food grade so a moot point.
