What is a continuous spiral screw for oil expeller?
An innovative design of continuous spiral screw was developed for screw-press oil expeller. The flow velocities in the down channel range from 125 to 175 mm s -1 through the length of screw from 150 to 500 mm for the screw drive of 48 rpm. The maximum pressure was built at the end of screw in the range of 9 – 10.57 x 10 5 Pa.
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.
Can a mechanical oil expeller press be used in small scale oil extraction?
A mechanical oil expeller press was designed and analyzed with simulation software (ANSYS) in this paper. This expeller can be used in small scale oil extraction. ASME shaft design code was used in designing the screw shaft of the press. Locally available material (mild steel) was used in manufacturing of the expeller.
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.
