A process for recovering meal and oil from fish offal comprises the steps of: transferring fish offal from a buffer container to a cooler; cooking the offal to obtain cooked offal; separating the cooked offal into solids and a mixture of oil, water and sludge by straining and subsequently pressing the cooked offal; heating said mixture of oil, water and sludge to obtain a coagulated mixture; separating by centrifuging the coagulated mixture into solids, stick water and oil; evaporating the stick water to obtain solids; drying the solids and milling the dried solids to obtain fish meal; and purifying the oil to obtain a purified oil. |
