An expeller press or ¡°screw press,¡± is a machine that presses seeds and nuts through a cavity and uses intense friction and pressure to extract oil. During this process, there isn¡¯t any added heat but since the seeds are pressed using friction, heat is created (around 140-210 F). Once the seeds are pressed, the oil is removed.
What is a screw press oil expeller machine?
The Screw Press Oil Expeller Machine is available in capacities of 50 kg/hr, 100 kg/hr, and 150 kg/hr. This versatile machine is designed to meet diverse oil production needs and efficiently extracts high-quality oil from a wide range of materials.

How does an oilseed press work?
When pressing seeds or other ingredients to create cold-pressed oils using an oilseed press, less heat is used. The seeds or ingredients are placed in the press and then are crushed by the machine to obtain the oil. Typically, when these ingredients are pressed, they are at a much lower temperature (122 F) compared to an expeller press.
How hot does an expeller press get?
As the raw material is pressed, friction causes it to heat. In the case of harder nuts (which require higher pressures) the material can exceed temperatures of 120 °F (49 °C). An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity.
