EU Support to Higher Education Institutions around the World 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.
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.
Can a single screw expeller extract oil from Pongamia Pinnata seeds?
The problems associated with the single screw expeller is that, it requires three or more passes to expel oil from seeds, which increases the production time and are also less efficient. In this paper, a counter rotating twin screw expeller is designed for extraction of oil from the Pongamia pinnata seeds.
