Choosing the Right Oil Press for Sesame Oil Production: Hydraulic vs. Screw Press

You're not alone if you're standing in front of two very different machines — one labeled “Hydraulic” and the other “Screw” — wondering which will give you the best return on your sesame oil production investment. The truth is, choosing the right press isn't just about horsepower or price. It’s about matching your scale, quality goals, and daily workflow.

Feature Hydraulic Press Screw Press
Avg. Operating Temp (°C) 35–45°C 60–75°C
Oil Yield (%) 42–50% 55–65%
Batch vs Continuous Batch Continuous
Maintenance Needs Low (manual pressure control) Moderate (gearbox, screw wear)

If you run a small family operation producing 5–10 kg/day of premium cold-pressed sesame oil, the hydraulic press wins hands-down. Its low heat output preserves aroma and nutrients — think of it as the chef's knife for artisanal oils. In contrast, a factory producing 100+ kg/hour needs speed and consistency — that’s where the screw press shines with up to 65% oil extraction efficiency.

"We switched from manual hydraulic presses to a semi-auto screw model at our 300kg/day facility — oil yield increased by 18%, and we reduced labor costs per batch by 30%." — Fatima Al-Mansoori, Owner, Gulf Seed Oils Co., UAE

Common Issues & Practical Fixes

Out of oil? High residual oil in cake? Here’s how pros solve it:

  • Low oil flow? Check pre-heating temperature — sesame seeds should be warmed to 40°C before pressing (especially in humid climates).
  • Pie crust too oily? Adjust screw speed — too fast = poor compression = higher residual oil (aim for 15–25 rpm).
  • Wear on rollers or screws? Clean after every 10 batches using food-grade mineral oil and soft brushes — don’t skip this step!

Pro tip: For better shelf life, store final oil in dark glass bottles under nitrogen flush — even small-scale producers report up to 6 months of stability vs. 2–3 months without it.
