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.
