The oil press machine, as a crucial piece of equipment in the plant oil production process, operates on a complex and efficient principle by exerting pressure on plant materials to extract valuable oil. Whether for edible oils, industrial oils, or oil components in cosmetics, the oil press machine quietly serves as a diligent contributor.

The working process of the oil press machine is a continuous and intricate operation that includes the following steps:

Raw Material Preparation: Plant materials such as peanuts, soybeans, sesame seeds, sunflower seeds, or other seeds, fruits, or nuts undergo cleaning, screening, and crushing to ensure their quality and uniformity, facilitating subsequent pressing.

Raw Material Feeding: Processed plant materials are fed into the oil press machine through the feeding inlet, entering the pressing chamber.

Pressing Process:

— Screw Oil Press Machine: A screw shaft propels the plant materials into the pressing chamber while applying pressure. The screw's spiral structure gradually squeezes the materials, extracting oil from them.

— Hydraulic Oil Press Machine: A hydraulic system applies high pressure to press the plant materials and extract oil.

Oil Residue Separation: The oil press machine separates oil and residue. Usually, a filtering screen or centrifugal separation is employed to separate the oil from the residue.

Oil Collection: The separated, pure oil is collected and stored as the final product.

Residue Discharge: The separated residue is discharged from the oil press machine and can be used as animal feed or for other purposes.

Cooling: Some oil press machines generate heat during operation and require cooling to ensure proper functioning.

Cleaning and Maintenance: After operation, the oil press machine needs to be cleaned and maintained to preserve its performance and extend its lifespan.
