An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Some other materials used with an expeller press include meat by-products, synthetic rubber and animal feeds. Raw materials enter one side of the press and waste products exit the other side.
What is an oil extraction machine?
This machine is commonly used in commercial or industrial where there is a need for large-scale oil production. They are engineered to efficiently process significant quantities of oilseeds or nuts, ensuring high productivity and optimal oil extraction yields.
When did expeller presses start?
The earliest expeller presses utilized a continuous screw design. The compression screws were much like the screws of a screw conveyor —that is, the helicoid flighting started at one end and ended at the other. Valerius Anderson invented the interrupted screw design and patented it in the year 1900.
