Types of Oil Press Machines

Our oil press machines are categorized based on processing capacity:

• Small Oil Press Machines – Ideal for startups or small-scale production.
• Large Oil Press Machines – Built for industrial-scale oil extraction.
• Pre-Press Oil Press Machines – Used in hybrid (mechanical + solvent) extraction systems.

Wide Application in Oilseed Processing

Our oil pressing equipment processes multiple oil-bearing materials, including:

• Rapeseed/Cottonseed/Soybean
• Peanut/Sesame/Sunflower Seed
• Corn Germ/Rice Bran/Wild Oilseeds

Oil Pressing Technology

Oil pressing, also known as expeller pressing, is a mechanical method that efficiently extracts oil from vegetables, nuts, and seeds through physical pressure. This process preserves natural flavors and nutrients without chemical solvents, ensuring safe and eco-friendly production.

The most advanced oil pressing equipment today is the screw oil press machine, which operates via a rotating screw shaft to apply continuous pressure. By adjusting temperature and pressure, it achieves high-efficiency oil extraction. Depending on production scale, screw presses can process from a few tons to over 1,000 tons per day.

Pre-Pressing + Solvent Extraction vs. Full-Pressing

In industrial production, a combined pre-pressing and solvent extraction process is commonly used to maximize oil yield:

• Pre-Pressing: A screw press extracts ~70% of oil, leaving 15-18% residual oil in the cake.
• Solvent Extraction: The cake is sent to an extraction plant to recover the remaining oil.
• This hybrid approach optimizes efficiency while improving raw material utilization.

Technological Advancements in Oil Pressing

Modern oil pressing technology is evolving toward intelligent and energy-saving solutions:

• Automated Control Systems – Precisely regulate pressure & temperature for higher yield + lower energy consumption.
• Low-Temperature Pressing – Enhances oil quality by preserving nutrients.
• Smart Monitoring – Real-time data tracking for predictive maintenance.

HuaTai’s oil press machines integrate these innovations, delivering 98% extraction rates with 30% less power usage than conventional models.
