Method of processing grains of a rapeseed comprising the steps of: - dehulling the grains , wherein the grains are passed through a roller nip between dehulling rollers , and separating hulls from a low-hull grain fraction by sieving and/or air separation such that the hulls remaining in the low-hull grain fraction do not account for more than 4 % by weight of the low-hull grain fraction , and - pressing cold-pressed rape core oil from the low-hull grain fraction , - wherein a water content of the low-hull grain fraction is from 4 to 7 % by weight, - wherein a cake temperature in a press cake being generated is limited to 70 °C, - wherein a first residual oil content is reduced to 18 to 28 % by weight of a dry matter of the press cake, and - wherein a part of the press cake is mixed with the low-hull grain fraction prior to the pressing and is pressed again, characterized in - that pressurized steam is supplied to the press cake and that the press cake is subsequently expanded to form collets , wherein the steam is metered such that the press case , under the influence of the steam , is temporarily heated up above 100 °C and the collets , after the expansion, have a temperature from 80 °C and 95 °C, - that the collets are extracted with an organic solvent, wherein a second residual oil content is reduced to 2 % by weight or less of a dry matter of the collets , and - that the part of the press cake is returned after the expansion. - dehulling the grains , wherein the grains are passed through a roller nip between dehulling rollers , and separating hulls from a low-hull grain fraction by sieving and/or air separation such that the hulls remaining in the low-hull grain fraction do not account for more than 4 % by weight of the low-hull grain fraction , and - pressing cold-pressed rape core oil from the low-hull grain fraction , - wherein a water content of the low-hull grain fraction is from 4 to 7 % by weight, - wherein a cake temperature in a press cake being generated is limited to 70 °C, - wherein a first residual oil content is reduced to 18 to 28 % by weight of a dry matter of the press cake, and - wherein a part of the press cake is mixed with the low-hull grain fraction prior to the pressing and is pressed again, - wherein a water content of the low-hull grain fraction is from 4 to 7 % by weight, - wherein a cake temperature in a press cake being generated is limited to 70 °C, - wherein a first residual oil content is reduced to 18 to 28 % by weight of a dry matter of the press cake, and - wherein a part of the press cake is mixed with the low-hull grain fraction prior to the pressing and is pressed again, - that pressurized steam is supplied to the press cake and that the press cake is subsequently expanded to form collets , wherein the steam is metered such that the press case , under the influence of the steam , is temporarily heated up above 100 °C and the collets , after the expansion, have a temperature from 80 °C and 95 °C, - that the collets are extracted with an organic solvent, wherein a second residual oil content is reduced to 2 % by weight or less of a dry matter of the collets , and - that the part of the press cake is returned after the expansion. <EOS>
