What Is a Screw Oil Press Machine?

The Vos screw oil press machine is a heavy-duty oil expeller designed for reliable and efficient extraction of oil from a wide variety of seeds—including soybean, peanut, rapeseed, sunflower seed, cottonseed, and more. As one of the most commonly used vegetable oil extraction solutions, it features high productivity, energy efficiency, and long service life.

Whether you operate a small oil mill or a mid-scale oil processing plant, this machine delivers stable output and easy maintenance. It can be used independently or integrated into a full oil production line with supporting equipment such as seed cookers, filters, and oil storage systems.

Crude Oil Quality from Screw Press Extraction

The crude oil extracted by Vos screw presses meets high-quality benchmarks:

Free Fatty Acid (FFA): ≤ 1.5% – Indicates low oil degradation and better shelf stability.

Moisture & Impurity: ≤ 0.3% – Ensures less refining is needed, improving processing efficiency.

Residual Oil in Cake: ≤ 7% – High mechanical efficiency minimizes oil loss during pressing.

This makes the extracted oil suitable for edible use, as well as for further refining into premium-grade products.
