Oilseed Expander Machine & Soybean Extruder – Increase Plant Capacity & Efficiency

Oilseed Expander Machine – Enhanced Oil Extraction

An oilseed extruder (also called an expander or extruding machine) is a vital machine in oil processing plants. It is specially designed for rice bran, soybeans, and other low-oil-content seeds, as well as pre-pressed cakes, to improve oil yield and processing efficiency.

Oilseed expanders are particularly beneficial in soybean oil plants, where they significantly increase production capacity and extraction rates. Beyond soybeans, they also efficiently process sunflower seeds, canola, cottonseeds, and other oil-bearing materials.

Why Use an Oilseed Expander Machine?

1. Higher Oil Extraction Efficiency

Traditional oil extraction from low-oil-content seeds (like soybeans) is challenging due to their dense structure. The oilseed expander machine applies heat, pressure, and mechanical shear, breaking down cell walls and increasing porosity for better solvent penetration during extraction.

2. Increased Processing Capacity in Soybean Oil Plants

Soybeans have a low natural oil content, making extraction difficult. The soybean extruder expands the material, improving oil accessibility and boosting extraction rates by up to 2-3%, leading to higher profitability.

3.Versatile for Multiple Oilseeds & Pre-Pressed Cakes

Processes soybeans, rice bran, sunflower, canola, and more
Enhances oil recovery from pre-pressed cakes (leftover from initial pressing)
Reduces waste and maximizes output

4. Improved Solvent Efficiency in Extraction

The expanded material has higher porosity, allowing solvents to penetrate deeper and extract more oil with less solvent consumption, reducing operational costs.

How Does an Oilseed Expander (Extruder) Work?

• Feeding: Oilseeds or pre-pressed cakes enter the extruder.
• Heating & Pressurization: The material is subjected to high temperature (100-130°C) and pressure (30-40 bar).
• Mechanical Shearing: The rotating worm shaft and stator pins break down cell structures, releasing oil.
• Sudden Pressure Release: When discharged, the material rapidly expands due to instant pressure drop, forming porous, high-strength pellets.
• Improved Extraction: The expanded material allows higher solvent absorption, increasing oil yield.
