For oilseed processors seeking higher yields with lower energy consumption, the evolution of spiral press technology is no longer optional—it's essential. Modern energy-efficient spiral oil presses featuring a dual-spiral shaft design are transforming how manufacturers extract oil from peanuts, soybeans, rapeseed, and other high-value crops.
Unlike traditional single-shaft extruders, dual-spiral shaft systems use synchronized helical threads that rotate in opposite directions. This creates a powerful shearing force—up to 40% greater than conventional models—that enhances oil cell rupture without excessive heat buildup. According to industry data from the International Journal of Food Engineering, this mechanical advantage increases extraction efficiency by 12–18% across various oilseeds under both cold-press and hot-press conditions.
Whether processing raw peanuts at 30°C (cold pressing) or pre-heated soybeans at 85°C (hot pressing), the dual-spiral system maintains consistent performance. For instance:
| Oil Type | Cold Press Yield (%) | Hot Press Yield (%) |
|---|---|---|
| Peanuts | 78% | 86% |
| Soybeans | 72% | 81% |
| Rapeseed | 75% | 84% |
The compact, modular construction uses hardened alloy steel components rated for over 10,000 hours of continuous operation. A built-in self-cleaning function—enabled by reverse rotation cycles every 30 minutes—reduces downtime by up to 35%. These features make it ideal for small-to-mid-scale producers aiming to meet EU and ISO standards for food safety and environmental compliance.
To maximize ROI, operators should conduct weekly checks on bearing temperature and torque levels using smart sensors. Properly maintained units can reduce electricity usage by 22% compared to older models—a key metric for companies targeting ESG goals. The press also minimizes waste by producing low-residue meal (<5% moisture content), which is perfect for animal feed or organic fertilizer applications.
As global regulations tighten around carbon emissions and resource efficiency, investing in dual-spiral technology isn’t just smart—it’s strategic. It positions your facility as a forward-thinking partner in sustainable food production.
