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.
Why do we need modified screw design for peanut oil screw press?
In this research, the modified screw design is considered in order to improve the oil capacity, the efficiency and number of cycles to failure and then to reduce the von-Mises stress, deformation and fatigue stress of automatic oil press machine by changing the pitch of screw shaft for peanut oil screw press expeller.
How to make peanut oil using an expeller press?
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 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.
