Zusammenfassung:Method for obtaining a meal with a high protein quality and extremely high biological value, and an oil with a low content of sulphur and FFA from marine raw material. The raw material is disintegrated (2) and heated (4) rapidly to 60 - 85C. The method is characterized in that one sieves (5) and presses (8) the mass prior to a lenient drying (15), and in that one separates (11) a fraction (7) from the sieving (5) in a decanter (11), and thereby preferably obtains a protein fraction, solids (14), oil (12) and stick water (13). The solids (14) is returned to pressing (8) or dried (15) directly. A part of the stick water is evaporated (20) and possibly dried, while the remaining part (23) possibly is recirculated. The oil (12) is removed from the plant.
