After oil pre-press machine , crude vegetable oil will be delivered to refining line , and the pressed cake will be sent to oil extraction line, using solvent to extract oil from oil cake , this process is called oil extraction.After oil extracted, mixed oil will pass through multi-effective evaporators to transform solvent into gas in order to get crude vegetable oil. And wet meal will be dried inside desolventizer,where the solvent will be removed too. Both solvent will be recovered after cooled down through condensers.Solvent is recyclying in vegetable oil extraction process.
Why is vegetable oil extraction machine important?
The oil residue inside cake is about 6.5% after oil press machine , this part of oil will be wasted if without oil extraction. After oil extraction machine , the oil residue inside meal is less than 1%, which greatly increases oil yield.
