Expeller Presses: A specific type of screw press that uses a continuous screw to mechanically squeeze oil out. Unlike solvent extraction methods common in large-scale industrial settings, mechanical pressing is a physical process that is often favored for its simplicity, cleanliness, and ability to produce high-quality oil without chemical additives.

Hydraulic Presses: Operating using a hydraulic ram, these presses apply slow, immense pressure to a cake of material already formed in a mold. The friction generated during this process can raise the temperature of the oil, which is a consideration for those seeking cold-pressed oil.
Preparation typically involves cleaning the seeds and, in many cases, roasting them to alter the oil's viscosity and protein structure, which can aid in a more efficient yield. This action breaks the oil cells and forces the oil to flow through small openings or缝隙, while the solid fiber or cake is expelled from the other end.

Screw Presses: These utilize a rotating screw (auger) to grind and press the material against a screen. Once inside the press chamber, a screw or a set of plates crushes the material.
