How to perform soybean oil solvent extraction process?

QIE GROUP modern soybean oil solvent extraction process system

1. Process innovation and upgrading

1. Intelligent leaching system

   • Using multi-stage gradient diafiltration technology (n-hexane/isopropanol 7:3 mixed solvent)

   • Integrated infrared online monitoring + automatic interlocking control system

   • Achieve dynamic optimization of solvent penetration rate of 0.8-1.2m³/ton·h

2. Wet meal processing technology

   • Pre-desolventization flash evaporation section (105℃/30kPa) reduces energy consumption by 12%

   • Microwave-assisted desolventizing reduces the residual solvent in the meal to ≤300ppm

3. Mixed oil refining

   • MVR mechanical vapor recompression system saves 40% energy

   • Molecular sieve adsorption unit controls acid value ≤0.8mgKOH/g

2. Safety and Environmental Protection System

3. Intelligent control system

1. Digital Twin Platform

   • Full-process 3D modeling and process optimization

   • Predictive maintenance (72-hour failure warning)

2. Safety protection system

   • 16-level interlock control (automatic nitrogen filling when oxygen content > 8%)

   • Complies with GB/T 17803-2018 safety standards

4. Economic Benefit Analysis

• Payback period: 2.3 years (40% shorter than traditional methods)

• Solvent loss: ≤0.5kg/ton of material (industry average 1.2kg)

• Comprehensive energy consumption: 18kg standard coal/ton of material (base value 25kg)

5. Technical Certification

• FSSC22000 Food Safety System

• ISO50001 Energy Management System

• Comply with the "Vegetable Oil Industry Water Pollutant Discharge Standard"
