Abstract: A method of producing a low-fat product from a starting material made of a fat and/or oil containing plant- or animal item includes providing the starting material at a temperature of at least 35° C. and extracting a greater part of the extractable oil and/or fat originally contained in the plant or animal item from the starting material using a first decanter centrifuge. The first decanter centrifuge is thereby leaving a residue of solids and liquids. The residue is forming the low-fat product.

Abstract: The present disclosure relates to a heavy phase liquid discharge element, a centrifugal separator comprising the element and to a method of separating two liquid phases. The heavy phase liquid discharge element comprises at least one inlet opening on a first side of the heavy phase liquid discharge element, the at least one inlet opening being adapted to face an interior of the centrifugal separator, and at least two separate outlet channels defining an outlet on the second side of the heavy phase liquid discharge element, wherein at least a portion of each of the outlet channels overlaps with the at least one inlet opening, thereby forming a liquid pathway between the at least one inlet opening and the outlet defined by the at least two outlet channels through which the liquid can pass. By this design, pressure losses in the heavy phase liquid outlets can be decreased.
