For entrepreneurs and small palm oil processors, mastering the refining process isn’t just about quality—it’s about efficiency, safety, and long-term profitability. Whether you're setting up your first mini-refinery or optimizing an existing one, understanding key parameters in de-gumming, acid removal, bleaching, and deodorizing can boost yield by up to 5–8% while reducing waste.
| Stage | Temp (°C) | Time (min) | Critical Tip |
|---|---|---|---|
| De-gumming | 60–70°C | 15–20 min | Use phosphoric acid at 0.1–0.3% for optimal water-soluble gum removal |
| Neutralization | 85–95°C | 25–30 min | Monitor free fatty acid (FFA) levels—target below 0.5% |
| Bleaching | 100–110°C | 30–45 min | Activated carbon dosage: 0.5–1.5% of crude oil weight |
| Deodorizing | 240–260°C | 60–90 min | Vacuum level must be maintained at ≤0.5 mmHg for effective volatile compound removal |
These numbers aren't arbitrary—they’re based on real-world trials from over 300 small-scale refineries using Qingpeng Group’s modular palm oil refining units. With precise control via PLC systems, operators report fewer manual errors and a 20% reduction in downtime due to misadjustments.
Manual temperature and pressure adjustments are risky and inconsistent. In contrast, our smart PLC system automates critical steps like vacuum switching during deodorization and alerts users when FFA exceeds safe thresholds. One producer in Indonesia saw a 12% increase in daily throughput after upgrading from manual controls to automated ones—without hiring additional staff.
And yes, maintenance matters. Regular cleaning of heat exchangers (every 2 weeks), checking seals on vacuum pumps (monthly), and calibrating sensors quarterly ensure consistent performance. These simple habits prevent costly breakdowns and extend equipment life beyond 8 years—even under heavy use.
