For small to mid-scale sunflower oil producers, even a 1–2% increase in extraction efficiency can mean the difference between profit and loss. That’s why we’re diving into a case study that demonstrates how one cooperative—processing approximately 15 tons of raw sunflower seeds per week—achieved a measurable 13% improvement in oil yield through targeted process optimization.
The cooperative had been using basic hydraulic presses and manual filtration systems for years. Initial analysis revealed their average oil yield hovered around 32%, far below the industry benchmark of 37–39% for cold-pressed methods. The root causes? Inconsistent seed preparation, poor temperature control during pressing, and inefficient filtering that led to significant residue loss.
| Process Step | Before Optimization | After Optimization |
|---|---|---|
| Seed Cleaning & Dehulling | Manual sorting, ~65% dehulling rate | Automated dehuller, ~92% dehulling rate |
| Press Temperature Control | Ambient temp (~25°C), inconsistent | Controlled at 50–55°C, stable output |
| Filtration Precision | Coarse mesh filter (100μm) | High-efficiency filter (20μm) |
By upgrading just three key steps—seed prep, press temperature, and filtration—the cooperative saw an immediate lift in yield. Notably, the use of a precision filter significantly reduced oil trapped in solids, contributing directly to the 13% gain.
If you're operating at similar scale (5–20 tons/day), these changes are not only achievable but economically impactful. For example, increasing yield from 32% to 35.6% means an extra 360 kg of oil per week from the same input volume—a real boost in revenue without expanding capacity.
What makes this case especially valuable is its focus on operational simplicity. No need for expensive automation or complex training. Just better tools, clear protocols, and consistent maintenance practices. As one team member noted: “It’s not about buying more machines—it’s about making every machine work smarter.”
