9 bolt oil expeller machine

An oil extraction machine, also called an oil press or expeller, uses high pressure and heat to “squeeze” the oils out of a plant product. Those products — including seeds, nuts, vegetables, fruits and leafy plants — release their oils through this mechanical process, which is often done without adding any chemicals.An expeller press is a machine that squeezes oil through a cavity, using continuous pressure and friction. Expeller pressing extracts about 87 to 95% of the oil out of the seed, so some oil is left over after the pressing process is completed. Expeller-pressed oil is commonly refined using this same process.
