Principle and Structure :
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 screw oil expeller, they have similar theories in screw expeller pressing. Because the screw type seed sesame oil cold press machine is mainly used by extrusion theory, so it is also called as oil extruder or oil extrusion process.

Features of  sesame oil cold press machine :

1. Made of high quality steel, wear-resistant and easy to clean.
2. With the properly designed pressing chamber, the increased pressure in the chamber highly improves working efficiency.

Working flowchart:

Small oil pressing line 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. The small oil pressing line or you can say small oil processing plant 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 pressing line is your first choice to start the oil making business.
