theAutomatic Seed Oil Extraction Machineor you can say small oil pressing machine is able to process a great many of vegetable oil seeds, such as soybeans, peanuts, cotton seeds, sunflower seeds, sesame seeds, palm kernel, coconut etc. Small investment, fewer land space, labor saving and wide application, the small oil press machine is your first choice to start the oil making business. It is fully adopted mechanical driven, it connects a series small oil processing equipment together to realize continuous oil extraction with easier operation and higher rate of oil yield. 

Working Principle
Oil press machine separates the oil from oil bearing materials by the pressing power which comes from the change of chamber volume, drive from screw worm, resistance of curve teeth at press rings and extrusion friction between oil materials. under the big pressure created in press chamber, the oil can be discharged from gap of press bars and oil trough of press rings. Either big scale and small scale of oil press machine, they have similar theories in screw expeller pressing.
