Oilve oil extraction machine _ how to extract olive oil?

Olive oil extraction process devides into several parts, grinding olives into a paste, malaxing the paste, and separation of oil from vegetable water and solids.

Olive oil extraction machine in grinding olives into a paste:
The two main types of crushers are stone mills and hammermills. There are also metal tooth grinders, although these are much less common. One of the most common myths about making olive oil is that stone mills are superior to hammermills and other metal crushers.
Olive oil extraction machine in malaxing the paste：
Most malaxers are made of a horizontal trough with spiral mixing blades, although some have vertical troughs. The vertical ones are generally known to produce a lower yield. Some are covered, and inert gases can thus be used to decrease oxidation.
Olive oil extraction machine in separation of oil from vegetable water and solids:
The next step is to separate the oil from the water and the paste. This can be done (or was historically done) in the many ways described below. Most systems fall into two main categories: presses and centrifugation. Nowadays, centrifuges are used almost exclusively, aside from old operations.
