Pretreatment is the crucial first step before pressing and solvent extraction in soybean oil production. Poor pretreatment can reduce oil yield and negatively affect the final oil quality.
Common Issues and Solutions:
1️⃣ Oil press wear or oil containing impurities? → Impurities not fully removed: Use efficient cleaning equipment (sieves, magnetic separators, destoners) to thoroughly eliminate contaminants.
2️⃣ Low oil yield and high residual oil? → Uneven crushing: Optimize crushing particle size based on oilseed characteristics to ensure uniformity.
3️⃣ Mild oil oxidation or quality decline? → Incorrect temperature and moisture: Use automated control systems to precisely regulate conditioning temperature and duration.
QIE GROUP’s high-efficiency soybean oil pretreatment equipment effectively removes impurities, increases oil yield, and ensures more stable and superior final oil quality.
