To make peanut oil using an expeller press, first preheat the press cage for about 10 minutes. Next, feed prepared peanut seeds into the feed inlet slowly and carefully, and start the press by turning the crank. Finally, let the oil settle for 24 hours or so in the bottle before use.
How do screw press oil expellers work?
The screw press oil expellers are reported to be more efficient than all other methods of oil extraction. The oil seeds fed through the hopper are crushed and transported by a rotating screw in a press barrel.
What is a screw press oil extraction machine?
Screw shaft is the main component of the oil extraction machine. Existing screw press oil expeller is the JY 200 machine with 220W motor power and 1500rpm. The von-Mises stress of existing screw design is 94.11 MPa and the modified screw design is 89.876 MPa for theoretical.
How does a screw press work?
Continuous transport of material by the screw shaft causes the pressure to increase to a level needed, which increases the friction inside the screw press and generates heat which lowers viscosity of the oil in the crushed seeds thereby increasing the oil flow rate. The oil and cake are usually collected at the oil outlet and press cake exit.
