In EPC project design, our focus extends beyond oil extraction efficiency. We also emphasize preparing oil-bearing materials in the optimal condition before they enter the solvent extraction plant.

Taking soybean oil processing and rice bran oil processing as examples, the introduction of extrusion technology during the oilseed pretreatment stage modifies the internal structure of the material, creating a more uniform porous matrix and providing superior mass transfer conditions for the subsequent solvent extraction process.

▸ Extruded materials offer improved permeability, enhancing solvent penetration and contact efficiency between solvent and material. This accelerates the solvent extraction process, promotes more complete oil release, and improves overall oil recovery rates.

▸ Combined with an optimized DTDC desolventizing system and advanced protein preservation technology, effective desolventizing is achieved while better protecting protein quality, increasing the value of soybean meal and rapeseed meal by-products.

In modern edible oil engineering, extrusion is not merely a pretreatment process. It serves as a critical bridge between raw material value and production efficiency, delivering comprehensive improvements in processing capacity, extraction performance, and overall product value throughout the solvent extraction plant.
