Rapeseed pretreatment

Rapeseed → Cleaning → Flaking → Steam Cooking → Pressing → Filtering → Pressed Rapeseed Oil

The efficiency of oil extraction and final oil quality depend heavily on the preparation of the rapeseed. Cleaning removes impurities that could damage equipment or affect flavor. Flaking and Steam Cooking are critical steps; proper heat and moisture treatment conditions the seeds, making the oil fluid enough to flow freely during Pressing. Effective Filtering then ensures a pure final product.

Solvent Extraction

The rapeseed oil extraction system uses the principle of mutual dissolution of solvent and oil to extract rapeseed oil from rapeseed cake.

The wet meal desolventization removes the solvent in the wet meal to obtain dry meal, which can be used to make animal feed.

The mixed oil treatment system removes the solvent in the rapeseed oil to obtain a relatively pure rapeseed oil.

The solvent recovery system recovers the solvents removed by the above two systems and reuses them.

Oil Refining

degumming, deacidification, decolorization and deodorization.

(1-10 tons/day intermittent refining, 10-50 tons/day semi-continuous refining, 30 tons/day full continuous refining)
