The hydraulic oil press machine adopts the oil pressure to transmit pressure. It squeezes the raw material in a static state to extract oil. The machine uses pure physical pressing and will not damage the composition of the oil. It is suitable for pressing peanuts, sesame, walnuts, olives, avocados, and other raw materials. The hydraulic oil extraction machine directly pours the roasted raw materials into the barrel for oil extraction. It has the characteristics of simple operation, high oil yield, and pure grease.
