torsiOn SYSTEM

Used in antiquity to extract olive oil without using any mechanical device. In recent times this procedure is applied to the olive paste obtained in pre-grinding or crushing.

The system consisted in inserting the olives, most likely of a high degree of maturity, into a sturdy cloth sack which was then tightly twisted by the means of some stakes or adapted wooden handles at both ends.

It was used in very remote times in cultures with emerging technical training. Relics and paintings can be found relating to this form of olive oil production in an Egyptian tomb from the dynasty. 2,500 to 2,300 BC.
