1. Advanced Pre-treatment: The Secret to Premium Aroma
For the 2026 market, quality begins with precision. Our 20-50 t/h lines utilize a multi-stage cleaning process (vibration screens, de-stoners, and magnets) to ensure raw material purity. The core advantage lies in our Thermal Conditioning: by roasting peanuts at 120-150°C, we trigger the Maillard reaction, essential for the rich, nutty aroma demanded by Grade-1 markets.
To prepare for extraction, peanuts are flaked to 0.3-0.5mm. This critical step ruptures cell structures, creating maximum surface area for solvent penetration during the leaching phase.
2. High-Efficiency Leaching & 99.9% Recovery
At the 20-50 t/h scale, efficiency defines profitability. Our Rotocel/Loop Extractors utilize n-hexane counter-current technology to push extraction limits, achieving a residual oil rate of ≤ 0.8%. The system operates under full Negative Pressure, preventing solvent leakage and ensuring safety.
- Solvent Recovery: Advanced paraffin absorption achieves ≥ 99.9% efficiency.
- Solvent Loss: Strictly controlled at ≤ 1.5 kg per ton of raw material.
- Oil Purity: Multi-stage vacuum evaporation ensures residual solvent in crude oil is < 50ppm.
3. Grade-1 Refining & High-Protein Meal
To reach Grade-1 export standards, our refining section integrates De-gumming, De-acidification, and Vacuum De-odorization. This process removes FFA and peroxides without damaging the oil's natural nutrients. Simultaneously, the DTDC Desolventizer processes the wet meal, keeping residual solvent < 100ppm while preserving high protein activity for the premium animal feed market.
