QIE GROUP solvent extraction plant technology delivers breakthrough performance through synergistic control of five critical parameters:
meal residual oil & solvent, crude oil flash point & FFA, and solvent consumption.
1. Precision Residual Control
• Ultra-low meal oil: Countercurrent miscella spraying with concentration gradients ensures residual oil below industry benchmarks.
• Near-zero solvent residues: Proprietary DTDC systems (pre-desolventizing→hot-air drying→cooling) in QIE solvent extractor system.
2. Enhanced Crude Oil Stability
• Negative-pressure evaporation minimizes processing temperatures；Elevates flash point (reducing flammability)；Suppresses FFA generation (nutrient preservation)
• Hydrocyclones + multi-stage filtration ensure color & acidity stability.
3. Closed-Loop Solvent Management
• Maximum solvent recovery: Submerged absorption towers + micro-negative-pressure operation.
• Energy cascade utilization: Exhaust heat from desolventizers powers evaporation, cutting steam needs.
4. Sustainable Production
• High flash point crude oil + leak-proof design mitigate storage and handling risks.
• Minimal solvent make-up + compliant discharge enable green "resource-product-renewable" cycles.
QIE GROUP oil solvent extraction machinery integrates DTDC, negative-pressure evaporation, and tail-gas absorption—redefining efficiency in solvent extraction.
