Optimizing Sesame Oil Extraction: How a Mini Screw Press Enhances Yield and Quality

For small-scale sesame oil producers, achieving consistent high yield while maintaining premium oil quality is both an art and a science. Whether you're processing raw sesame seeds from local farms or handling varied batches with different moisture levels, the right equipment makes all the difference.

Understanding Cold vs. Hot Pressing in Sesame Oil Production

Research shows that cold-pressed sesame oil retains up to 25% more antioxidants compared to hot-pressed versions—critical for health-conscious markets in Europe and North America. However, hot pressing (typically at 70–85°C) increases extraction efficiency by 10–15%, especially when dealing with higher moisture content seeds. The choice depends on your target market’s preference: cold-pressed for premium labels, hot-pressed for cost-effective bulk production.

Why Spiral Press Technology Works Best for Small-Scale Operators

A well-designed mini screw press allows real-time adjustment of pressure, speed, and feed rate—key parameters that directly impact oil yield and clarity. For example, a typical 300 kg/h capacity unit can increase output by 12–18% when properly calibrated for each batch. This adaptability ensures consistent performance even when seed quality fluctuates seasonally—a common challenge for regional processors.

Our clients in India and Nigeria report average improvements of 14% in oil recovery after implementing proper parameter tuning based on seed moisture (measured via NIR analyzers). These gains translate into better margins without additional labor or energy costs.

Common Challenges—and Practical Fixes

One frequent issue is low oil flow due to improper pre-treatment. If seeds aren’t cleaned thoroughly, foreign particles can clog the press screen, reducing throughput by up to 30%. Another problem? Overheating during hot pressing—this degrades flavor compounds and reduces shelf life. We recommend using a temperature-controlled hopper and conducting weekly calibration checks on torque sensors.

In Ethiopia, a cooperative increased their daily yield from 40L to 52L within two months simply by adjusting the screw speed according to seed type—no new machinery needed.

Whether you’re scaling up from home-based production or optimizing an existing facility, understanding these technical nuances is essential. With smart process control and the right tool—like our compact screw press—you’ll not only boost yields but also build brand trust through consistent product quality.
