Brief
In traÂdiÂtional mills, olive oil was extracted using presses. There are still some around in traÂdiÂtional setups, but most proÂducÂers use cenÂtrifuges to draw oil from crushed olives. Centrifuges spin the oil from the fruit, just like the final cycle of your clothes washÂing machine when it spins fast to release the water.
