How an Oil Expeller Works

An oil expeller is a machine used to extract oil form seeds. It squeezes the seeds under high pressure until all the oils are extracted. The seeds used include nuts, corn, algae and many others. They are fed into the heated machine and then the oil is allowed to seep though small holes that do not allow the remaining to pass.
When buying an expeller it is important to make sure that it is an efficient one since some expellers can not extract all the oils. This may not be a problem in small scale production, but in large scale production you may end up losing a lot of oils. Besides, you can use the cake that remains as animal feed or to wash dishes. However, you can use a solvent if you do not want to have any oil traces in the wastes.
The oil pressed by an oil expeller has numerous health benefits. It is rich in omega 3 fatty acids which are known to improve the immune system to keep your body free from several diseases. The oil can be sued to cook food or to add flavor to dishes. Each seed and nut produces a different amount of oil after pressing and if the pressing is not thorough the oil will have impurities. This is why it is important to refine the oil in order to get rid of these impurities.

An oil expeller is used to extract oil from nuts and seeds. The expellers come in different sizes to suit your production needs.
