In the past people used to extract oil manually but this has changed over the years although in some countries they still use the traditional methods of oil extraction. In order to produce high quality oil from oil bearing products, it is recommended that you consider using the solvent extraction plant. In addition, it is capable of extracting large quantities of oil provided that you know how to use it well. There are some solvent extraction plants that are able to extract high quality oil at extremely low temperatures under a vacuum.

However, there are others that rely on the conventional mechanical pressing under high temperatures and pressure. Though most solvent extraction plants still continue to use the mechanical pressing, the sad news is that when you extract oil at high pressure and temperature, it is susceptible to oxidation. This implies that the final product will be compromised and will not be as pure and excellent as the one that has been produced at low temperatures in a vacuumed environment. The process of solvent extraction is taken through a chain of the following steps though they are not the same in all solvent extraction plants:

• Preparation

• Extraction

• Distillation

• Meal toasting

• Recuperation

• Meal finishing
