Export-focused edible oil processors face a precise equation: consistent quality that meets multi-market compliance, with predictable throughput and controlled unit costs. Penguin Group’s one-stop rapeseed oil processing equipment solution is engineered to deliver that balance—combining grain & oil processing technology, robust automation, and best-practice refining control. This solution covers the entire chain—from seed intake and pretreatment to pressing/extraction and physical-chemical refining—so producers can scale B2B rapeseed oil production with confidence.

The integrated line minimizes interfaces and loss points while maximizing yield and quality. Typical canola/rapeseed seed oil content: 38–45%. With optimized pretreatment and pressing, crude oil yield reaches 90–93% of seed oil potential; after refining, 95–97% yield relative to crude is achievable under controlled parameters.
Optional modules: solvent extraction post pre-pressing (to reduce residual oil in cake to 0.8–1.2%), winterization/fractionation (for specific markets), and in-line dry fractionation for specialty applications.
Controlling temperature, time, and pressure at each stage stabilizes flavor, color, and nutritional markers (e.g., tocopherols), while minimizing FFA, PV, and anisidine. The following reference ranges are widely used by efficient B2B rapeseed oil production lines:
| Stage | Typical Setpoints | Impact on Quality & Yield |
|---|---|---|
| Conditioning | 60–75°C, 15–25 min, MC 6–8% | Cell rupture, lower press power, improved oil release |
| Screw Pressing | 90–110°C (hot press); 40–60°C (cold) | Residual oil in cake: 6–8% (pre-press); ≥12% if full cold press |
| Degumming | Water/acid 0.1–0.3%; 70–80°C; 20–30 min | Phospholipids ↓ to ≤10–30 ppm (for physical refining) |
| Neutralization (if chemical) | NaOH 12–18°Bé; 60–70°C | FFA removal to <0.1–0.3%; manage soapstock loss |
| Bleaching | 0.5–1.0% earth; 90–110°C; <50 ppm moisture | Color correction; metals and peroxides reduction |
| Deodorization | 180–230°C; <3 mbar; 2–4 h; sparge steam 1–2% | FFA to <0.05–0.1%; neutral flavor; minimize trans/isomerization |
Switch between water, acid, or enzymatic degumming depending on target markets. For physical refining at scale, acid or enzymatic routes help push phosphatides toward <30 ppm and metals below 0.1 ppm, lowering bleaching earth consumption by 10–20%.
Chemical neutralization is robust for variable crude quality but adds soapstock handling. Physical refining (steam stripping under deep vacuum) can reduce total neutral oil loss by 0.3–0.8% when gums are very low—ideal for consistent, high-volume B2B rapeseed oil production.
Use low-peroxide earth; tight control of moisture and temperature prevents post-bleach PV rebound. Inline chlorophyll monitoring helps ensure export grade color in the 10–15 Lovibond range (5.25” cell), depending on specification.
Deep vacuum (<3 mbar) and optimized residence time protect natural tocopherols (often >70% retention vs. crude), while meeting sensory targets for EU/US buyers. Integrate heat recovery to cut steam demand.
Result: lower risk during customer audits and faster market clearances in EU, North America, MENA, and APAC.
| KPI | Typical Result | What It Means for Exporters |
|---|---|---|
| Refined oil yield | 95–97% of crude | More sellable liters per ton; compounding margin over volumes |
| FFA (final) | <0.05–0.1% | Meets stringent buyer specs; reduced claim risk |
| Color (Lovibond) | 10–15 Y; 1.0–1.5 R (5.25”) | Shelf appeal and consistency across markets |
| OEE (refinery) | ≥85% in mature operations | Predictable lead times for B2B contracts |
For a 100 TPD line operating 330 days/year, a 0.8% yield gain and 6% utility savings can translate to mid six-figure annual value, before logistics benefits from fewer reworks/claims. Exact ROI depends on crude quality, energy rates, and product mix.
Pre-press + physical refining with energy integration. KPIs: refined yield +0.9%, earth consumption −15%, FFA final 0.06%. Lead time adherence improved (on-time shipments +8%) due to OEE stabilization and recipe control.
Flexible degumming (switchable acid/enzymatic) and chemical neutralization for variable seed quality. Achieved color 12Y/1.2R consistently, reduced off-spec batches by 70% within first quarter, enabling expansion into EU private label channels.
Reference timelines: 50–100 TPD pre-engineered lines in ~12–16 weeks; 200–300+ TPD custom plants in ~20–28 weeks, subject to compliance scope and utilities readiness.
