30 Kg Olives per hour press

The Aquarius comprises separate pieces of machinery for each of the 3 processes of olive oil production: These processes are:

 Milling - to reduce the olives to a paste;

 Malaxation - to break down the cells to release oil;

 Pressing - to extract the olive liquids. The objective has been to achieve a higher level of quality oil, while keeping the whole process as simple as possible.




The hammer mill employs a mechanism which is of a similar size to that used in a full size press and, using a 1.5hp motor, produces a  fine paste. The mill sits on it's own stand and can be raised and lowered over a 20 litre stainless steel stock pot (or some other suitably sized container of your choice). The olives are poured into a sorting tray where leaves can be removed and then pushed over the feed tube. A 15kg batch of olives takes about 6 minutes to mill.

The malaxator again maintains simplicity of operation by slowly revolving the pot of paste (typically 15kg) on a turntable, malaxation being achieved by 2 adjustable stainless steel paddles held vertically by a frame over the pot. For best results malaxation should take about 50 minutes and for this reason two turntables are teamed on the same drive so as to allow a second pot of paste to begin malaxation once more olives have been milled. The long slow malaxation transforms the paste into a gleaming mixture which is already releasing much of the available olive oil.

The oil press is an elegant and ingenious machine which enables enormous pressure to be applied to the olive paste. 15kg of olive mixture takes about 25 minutes to press (including filling and emptying). First the top screw is turned to apply moderate pressure, then the hydraulic jack is gently foot pumped to apply up to 10 tonnes of pressure from below. The olive paste is contained in a stainless steel cylinder with slits cut in it which sits in a  pot with a pouring spout.  By using a series of acrylic mats and stainless steel plates, the press achieves close to total extraction of the oil that can be extracted by cold pressing. The whole top assembly swings open for filling and emptying.    


After pressing it is necessary to separate the olive oil. The process of separation is largely a matter of waiting for gravity to do most of the work, then drawing off either the watery sediment or the oil which floats on top of it. A production separator has been developed and this is described on the Separator page.
