Nextly, a separator will be in charged to eliminate waste water and keep the solid olive oil to a storage tank. In a proper way, oil will be cleaned and freshed in storage chamber. Ultimately, to categorize each oil will have unique way to make, like virgin oil and extra version itself submerge in a filtration or refining to make refined olive oil.
