Hydraulic Press Line Automation: How QIE’s System Elevates Oil Quality & Efficiency

In the competitive world of edible oil production, efficiency and purity aren’t just goals—they’re non-negotiables. At QIE Group, we’ve engineered a fully automated hydraulic press line that transforms traditional oilseed processing into a precision-driven operation. Based on real-world performance across over 40 global installations, this system consistently delivers up to 22% higher yield and reduces impurities by 35% compared to semi-automated setups.

Key Process Stages That Drive Superior Oil Quality

The core of our automation lies in its integrated workflow—from seed prep to final filtration. Each stage is optimized for consistency and quality:

  • Seed Cleaning & Pre-Treatment: Magnetic separators remove iron particles (down to 0.1 mm), preventing wear on machinery and contamination in refined oil.
  • Weight-Based Feeding System: Real-time weighing ensures uniform feed rate—critical for consistent pressure during pressing. Our clients report 98% process stability when using this feature.
  • Advanced Hydraulic Pressing: With adjustable pressure (up to 35 MPa) and temperature control (40–70°C), it adapts to different oils like soybean, sunflower, or palm, maximizing oil extraction without overheating.
  • Specialized Filtration: Multi-stage filters (mesh + activated carbon) reduce free fatty acids (FFA) from 3.5% to under 0.5%, meeting international standards like ISO 5559.
Oil Type Avg Yield Increase (vs Manual) Impurity Reduction
Soybean Oil +18% 32%
Sunflower Oil +24% 38%
Palm Oil +15% 28%

What sets QIE apart isn’t just automation—it’s intelligence. The system uses predictive maintenance algorithms based on vibration and thermal data, reducing unplanned downtime by 40% in industrial trials. One German OEM reported saving €12,000 annually in maintenance costs after switching to our solution.

Why This Matters for Your Business

Whether you're producing bulk commodity oils or premium specialty grades, flexibility and reliability are key. Our system supports multiple oil types with minimal changeover time (under 30 minutes per batch). It also integrates seamlessly with existing ERP systems via API, enabling real-time monitoring and compliance reporting.

With proven results from operations in Brazil, India, and Turkey—and over 15 years of field testing—we don’t just build machines. We build trust. Every unit comes with 24/7 remote diagnostics, on-site training, and a 2-year warranty covering parts and labor.

If your goal is higher yield, cleaner oil, and fewer operational headaches—this is the future of oil processing.
