FIELD: agriculture.SUBSTANCE: group of inventions relates to agricultural industry. Fraction of sunflower extraction cake containing at least 50 % protein and less than 10 % crude fibres is obtained as follows. Initial material is prepared by deagglomeration of sunflower extraction cake, containing at least 30 % protein and having a moisture content less than 12 % into particles sized less than 5 mm. Obtained initial material is sifted to obtain following fractions: fraction F-b1, wherein particle size ranges from d1 to d2, fraction F-b2, in which particle size ranges from d3 to d1 and fraction F-b3, in which particle size is less than d3. Fraction F-b1 is deagglomerated and sifted to obtain following fractions: fraction F-c1, wherein particle size ranges from d4 to d5 and fraction F-c2, wherein particle size is less than d4. Fractions F-b2 and F-c1 are air-sifted to obtain following fractions: fraction F-d1, wherein particle size is more than d6, fraction F-d2, wherein particle size ranges from d7 to d6 and fraction F-d3, wherein particle size is less than d7. Fraction F-d1 is deagglomerated and sifted to obtain fraction F-e1, wherein particle size is less than d8 and/or fraction F-d2 for producing fraction F-e2, wherein particle size is less than d9 and/or fraction F-d3 for producing fraction F-e3, wherein particle size is less than d10. Fractions F-b3, F-c2, F-e1 and/or F-e2, and/or F-e3 are mixed to produce fraction F. Wherein d1 ranges from 600 to 1,600 mcm, d2 ranges from 2,000 to 5,000 mcm, d3 ranges from 150 to 500 mcm, d4 ranges from 150 to 500 mcm, d5 ranges from 600 to 1,600 mcm, d6 ranges from 800 to 1,000 mcm, d7 makes 500-750 mcm, d8 ranges from 200 to 600 mcm, d9 ranges from 200 to 600 mcm and d10 ranges from 200 to 600 mcm. Use of sunflower extraction cake for animal feeding.EFFECT: group of inventions enables to manufacture a product rich in protein, with low content of crude fibres.15 cl, 3 dwg, 1 tblГруппа изобретений относится к сельскохозяйств
