Cooking oils are daily necessities used in all over the world and different types of oilseeds are grown at everywhere. Besides food purpose, vegetable oil is also the source of bio-diesel, the new enviorenmental friendly fuel.

The cake from oil press section could also be used as raw material for solvent extraction plant, the chemical way to extract oil. This kind of extraction uses chemical solvent to dissolve oil content contained in cake or oil seeds. Oil is collected by vaporizing solvent out which is later recycled. In configuring the solvent extraction plant, pre-pressing may be involved in which case seeds are lightly pressed leaving about 14% to 18% oil in pressed cake. Solvent extraction will further process these cakes and leave only 2% oil in the final cake (meal). This method results in higher capacity, Lower power consumption, lower wear & tear / maintenance and high extract efficiency. Thus it could be used as complement equipment to extract the oil remained in cake, which gives extra profit to entrepreneurs. Or the solvent extraction could be configured to process raw soybean and some other seeds directly.
