The soybean oil solvent extraction process directly determines oil purity and safety—high residual oil and solvent levels result in edible oil that is neither fragrant nor safe!
Common Issues and Solutions:
1️⃣ Uneven solvent penetration causing incomplete oil extraction and high residual oil: Optimize the solvent extraction tower design, maintain an appropriate bed thickness, and ensure uniform solvent circulation.
2️⃣ Excessive solvent residue affecting flavor and safety: Employ high-efficiency desolventizing and solvent recovery systems to strictly control residual oil levels.
3️⃣ Improper temperature control leading to oil oxidation and quality decline: Use intelligent temperature control systems to precisely monitor solvent extraction temperature and time, ensuring consistent oil quality.
