Optimizing Sesame Oil Processing: How Automation Ensures Consistency & Premium Quality for Export Markets

In the global edible oil market, consistency isn't just a goal—it's a requirement. For sesame oil producers targeting export markets like the EU, Japan, and the Middle East, even minor variations in flavor, clarity, or oxidation stability can lead to rejection at customs or loss of premium brand trust. In my 18 years working with food-grade oil plants across Asia, Africa, and Latin America, I’ve seen how automation transforms raw processing into predictable, high-value output.

From Seed to Bottle: Key Stages That Define Quality

The industrial sesame oil process typically includes:

• 1. Raw Material Cleaning (85–92% efficiency) – Removes dust, stones, and foreign seeds using air aspiration and magnetic separators.
• 2. Pre-Pressing & Dehulling (70–80% seed recovery) – Increases oil yield by breaking shells before pressing.
• 3. Temperature-Controlled Pressing (110–140°C range) – Critical for preserving aroma compounds and minimizing thermal degradation.
• 4. Filtration & Degumming (removes phospholipids, proteins) – Improves shelf life from 6 months to over 12 months.
• 5. Refining (acid neutralization + bleaching) – Achieves free fatty acid content < 0.1%, meeting international standards such as ISO 2917.

Why Temperature Control Is Non-Negotiable

Many small-scale processors overlook this step—but it’s where quality diverges. A study by the International Journal of Food Engineering found that when press temperatures exceed 145°C, volatile aromatic compounds degrade by up to 40%, leading to “flat” or off-flavors. Conversely, maintaining precise control between 110–135°C ensures optimal extraction while retaining the distinctive nutty notes that premium buyers demand.

One client in Nigeria used manual temperature regulation—resulting in batch-to-batch variation of ±15°C. After installing PLC-based temperature feedback loops, their consistency improved to within ±2°C. Their export orders doubled within six months.

How Automation Transforms Your Output

Modern control systems don’t just monitor—they learn. With sensors feeding real-time data to SCADA platforms, you get:

• Real-time adjustment of pressure, heat, and flow rates
• Batch traceability via digital logs (critical for HACCP audits)
• Predictive maintenance alerts based on motor vibration patterns
• Remote diagnostics for technicians in different time zones

Actionable Tips for Small & Medium Enterprises

If your plant is still relying on manual controls or semi-automated setups, consider these steps:

1. Start with a pilot project—automate only the pressing and filtration lines first.
2. Use open-standard protocols like Modbus TCP to avoid vendor lock-in.
3. Train operators on interpreting dashboard metrics—not just pushing buttons.
4. Integrate with ERP systems to track yield per batch and reduce waste.

Remember: automation isn’t about replacing people—it’s about empowering them to focus on what matters: quality assurance and continuous improvement.
