Sunflower Oil Extraction Machine Overview

The Vos sunflower oil press machine is a robust screw oil expeller designed to efficiently process sunflower seeds with high oil content. This equipment combines precision engineering with reliable mechanics to deliver stable output, high oil yield, and easy maintenance. It is well-suited for individual oil workshops and commercial edible oil factories aiming to produce high-quality unrefined sunflower oil.

Whether used independently or integrated into a full sunflower oil production line, Vos presses offer flexible operation for various processing volumes.

How the Sunflower Seed Pressing Machine Works

Sunflower seeds are cleaned and, if necessary, dehulled to remove hard shells.
The seeds are then slightly heated to improve oil flow and reduce viscosity.
Prepared seeds enter the screw press chamber, where a rotating shaft compresses them gradually.
Oil is released through small gaps in the press cage while residual cake is discharged from the outlet.
The crude oil is collected and typically filtered to remove sediment or impurities.

Vos sunflower oil press machine ensure optimal oil extraction when paired with proper seed pretreatment and filtration systems.

Applications in Global Seed Oil Processing

Vos sunflower seed oil expellers are widely adopted in countries like Ukraine, Russia, Argentina, and Kenya, where sunflower oil is a primary edible oil. These machines are favored for their robust construction, ease of operation, and consistent oil output.

They are also compatible with oil refining systems, filtration units, and storage tanks, allowing small processors to upgrade into a full production system over time.
