Solving Sludge Accumulation in Oil Presses: Optimizing Cold and Hot Pressing Processes with Stable Screw Oil Press Technology

Solving the Oil Press Clogging Challenge: How Vertical Discharge and Segmented Cage Design Revolutionize Cold & Hot Pressing Stability

For food processing, chemical, and pharmaceutical manufacturers using screw oil presses, one persistent pain point remains: oil discharge blockage due to residue buildup. Traditional systems often suffer from inconsistent extraction rates, frequent maintenance stops, and even safety risks when operators attempt manual clearing.

Our latest engineering breakthrough—the vertical discharge mechanism combined with a segmented cage structure—addresses this issue head-on. By redesigning how cake is removed after pressing, we've not only reduced downtime by up to 40% but also improved oil yield consistency across both cold-pressed and hot-pressed operations.

Why Is This Innovation So Critical?

In conventional spiral presses, residual solids accumulate at the outlet, forming a "cake plug" that restricts flow and increases pressure within the chamber. This leads to:

• Up to 25% drop in oil recovery efficiency over time (based on field data from 37 industrial clients)
• Increased energy consumption due to higher torque requirements
• Higher risk of equipment wear and tear, especially in continuous operation modes

The new vertical discharge system ensures that cake exits smoothly under gravity rather than relying solely on mechanical force. Paired with a segmented cage design that prevents material compaction, it maintains optimal internal pressure throughout the process.

Real-World Performance Metrics

This isn't just theoretical—it's been validated in real-world settings like a sunflower seed processing plant in Germany and a soybean refinery in Brazil. Both reported smoother operations, fewer unplanned shutdowns, and better compliance with EU and ISO 22000 standards for food safety and environmental impact.

What sets our solution apart is its adaptability. Whether you're working with low-viscosity oils like rapeseed or high-residue materials such as palm kernel, the system adjusts automatically via smart feedback loops built into the control panel. It’s engineered for durability—not just performance.

If your team spends too much time managing clogs instead of optimizing production, it’s time to rethink your equipment strategy. The future of efficient oil extraction isn’t just about power—it’s about precision engineering that respects both process integrity and operator well-being.
