How a Hot Press Sesame Oil Expeller Boosted Production Efficiency — Real Client Case Study

In the competitive world of edible oil manufacturing, every percentage point in yield and efficiency matters. In this article, we’ll break down how a hot press sesame oil expeller helped a mid-sized food processing plant in Turkey increase its oil output by 18% while reducing energy costs per ton by 12%, all without compromising quality.

The Science Behind Hot Press Technology

Unlike cold pressing—which preserves more flavor but yields less oil—hot pressing involves heating raw seeds to 70–85°C before pressing. This softens cell walls and breaks down proteins, allowing up to 25% more oil to be extracted from the same quantity of raw material. According to our internal testing across 30+ clients, this method increases extraction efficiency from ~62% (cold press) to ~78% (hot press).

Balancing Yield and Quality with Precision Control

The key to successful hot pressing lies not just in heating—but in controlling temperature and time precisely. Overheating can degrade antioxidants like vitamin E or cause oxidation, leading to rancidity. Our engineers recommend maintaining seed temperature at 75°C ± 2°C for 15–20 minutes before pressing. A client in Spain reported that after implementing this protocol, their oil’s free fatty acid level dropped from 1.8% to 0.9%, improving shelf life significantly.

Real Results from a Real Client

A family-run oil mill in Izmir, Turkey, upgraded from an old cold press system to a modern hot press sesame oil expeller. Before the change, they processed 5 tons/day with 63% oil yield. After installation, they achieved:

• Increased daily output: 6.5 tons/day (up 30%)
• Higher oil yield: 77% vs. 63%
• Lower operating cost: €0.18/kg vs. €0.23/kg
• Reduced labor needs: One operator instead of two

This translated into an annual savings of over €35,000 and faster turnaround times for bulk orders—a critical advantage when serving supermarkets in the EU market.

If you’re looking to optimize your sesame oil production process—whether you're scaling up or simply seeking better margins—this technology is worth serious consideration. It’s not just about higher yields—it’s about smarter, more predictable, and sustainable operations.
