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.
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 is peanut oil pressed?
Peanut pressing is performed with a continuous press. Following the pressing process, a decision is made on the volume and the temperature of crude oil, as well as on pressing time. The additional steps include the natural precipitation of crude oil and the vacuum filtration of crude oil to obtain cold pressed oil.
Can a screw press Express Oil from peanut oil?
The unit was tested and found capable of expressing oil from small quantities of the oil-seed, i.e. peanut. The crude oil obtained was found to be of high quality as its characteristics were comparable to literature values for peanut oil. It is important that the screw press be heated so as to heat the meal as the latter is being pressed.
