Brief introduction of oil press 
oil press machine, which is also called oil expeller, oil extraction machine or oil mill, It can be used for various raw materials, such as soybeans, peanuts, cotton seeds, rape seeds, sesame seeds, sunflower seeds, canola seeds, coconut seeds, tea seeds, palm seeds and jatropha seeds.

Working principle of oil press
Screw expeller pressing is to separate 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 screwhemp eucalyptus oil extraction machinefor algae, they have similar theories in screw expeller pressing. Because the screw type seedsesame eucalyptus oil extraction machineis mainly used by extrusion theory, so it is also called as oil extruder or oil extrusion process
