For decades, mechanical pressing has been the go-to method for extracting oil from soybeans in feed production. However, it often leaves behind residual oil levels of 4–6%, limiting both nutritional value and economic efficiency. Enter advanced solvent extraction technology—a proven solution that reduces soybean meal oil content to just 1–2%, significantly boosting feed quality while cutting waste and energy costs.
Solvent extraction leverages the natural affinity between hexane (or alternative green solvents) and vegetable oils. In a well-controlled system, the solvent dissolves up to 95% of oil from pre-pressed flakes—far surpassing what mechanical presses can achieve. Key parameters like temperature (45–55°C), solvent-to-material ratio (1.5:1), and contact time (30–45 minutes) must be optimized to maximize yield without damaging protein structure.
According to a 2023 study by the International Feed Industry Federation, facilities using modern solvent systems report an average 18% increase in protein concentration in final feed粕 compared to traditional methods—directly improving livestock performance metrics such as weight gain and feed conversion ratios.
A critical advantage of today’s solvent extraction units is their integrated recovery systems. Modern distillation columns recover over 99% of solvent, minimizing environmental impact and reducing raw material consumption by up to 30%. This not only meets EU and US EPA standards for VOC emissions but also cuts operational costs significantly.
In one case from a mid-sized feed mill in Brazil, implementing a closed-loop solvent recovery unit reduced annual solvent usage from 120 tons to just 35 tons—saving $45,000 per year in procurement alone.
Our client in Thailand upgraded their existing press-based setup with a full-scale solvent extraction line in Q2 2024. Within three months:
