Vegetable Oil Press

Vegetable oil press can either be done using the traditional or modern methods of extraction. The traditional methods tend to be less efficient compared to the other methods. If you want to extract vegetable oil in smaller quantities, then the traditional methods may fit the bill. However, if you wish to extract large volumes of oil, you need to use the commercial methods whose efficiency levels are very high. The use of carbon dioxide as a solvent is recommended for the commercial methods of vegetable oil press. They can also be cold or expeller pressed and extraction is done using hexane.

Vegetable oil is mostly extracted from beans, seeds and nuts. Crushed seeds, olives and coconut meat are among the vegetables which are placed under traditional methods in order to extract the oil found therein. Salt water is used to boil them first before oil is skimmed from the top. When they are cold pressed, the seeds must be husked and then cleaned before extraction of oil can proceed. The seeds from which the oil will be extracted must not exceed 120 degrees in Fahrenheit. The use of an expeller is crucial to the pressing of vegetables for the oil that is contained in them.

Expeller and solvent extraction are important aspects of the vegetable oil press. Solvent extraction is used in a situation where there is need to extract oil from seeds weighing not less 200 tons every day. Before you carry out expeller extraction, you must ensure that the seeds are first heated until they attain temperatures in the range of 110-180 degrees Fahrenheit. Extraction by carbon dioxide is also growing in importance. It is crucial for the carbon dioxide to first be converted into water before the extraction of vegetable oil can be started. This method produces waxier, thicker and heavier oil.
