Abstract

In the extraction of fats from vegetable materials with an organic solvent, the vegetable material is pretreated with an aqueous solution of a volatile alkali such as ammonia or water soluble amines, e.g. methylamine or hydrazine, whereby mucilaginous and bitter ingredients are removed therefrom. Soya beans, corn germs, or flax or cotton seeds are treated below 180 DEG F. with a small amount of aqueous ammonia, and after agitating and standing the aqueous liquor is removed from the beans by heating and the beans are flaked or powdered. An organic solvent such as di- or trichlorethylene, carbon tetrachloride, benzene, petroleum naphtha or an alcohol-ether mixture, is then added to extract the fatty oil. The oil extract is decanted, filtered and part of the solvent removed by distillation. The concentrated extract is treated with a filter aid such as kieselguhr or decolorizing carbon and after filtration the balance of the volatile solvent is distilled off. Final traces of solvent are removed by passing a current of dry steam, warm air or carbon dioxide through the oil. The extracted residue is dried by heating, preferably in vacuo, in a current of a gas and the residue is suitable for cattle feed. The process may be applied to the recovery of oil from press cakes.
