Method of producing a low-fat product and a system for producing a low-fat product

A method of producing a low-fat product from a starting material, the method comprising:

• providing the starting material at a temperature of at least 35° C., the starting material comprising a plant or animal item, said plant or animal item comprising fat and/or oil;
• and
• extracting an oily phase having a greater part of extractable oil and/or fat contained in the plant or animal item from the starting material using a first decanter centrifuge, thereby leaving a slurry phase having a residue of solids and liquids, the residue forming the low-fat product,
• wherein the first decanter centrifuge is a two-phase type decanter comprising a first large end hub, a first small end hub opposite the first large end hub and a first bowl extending therebetween in a cylindrical shape adjacent the large end hub and in a conical shape adjacent the small end hub,
• wherein the first large end hub has a first light phase discharge defining an oil phase outlet for the oily phase and the first small end hub has a first heavy phase outlet allowing water and solids defining the slurry phase to be discharged from a slurry outlet, and
• wherein the first light phase discharge has a weir set for defining a first liquid level at a specific distance from an axle allowing the oily phase to be discharged at the oil phase outlet while preventing the water and solids from being discharged as the slurry at the oil phase outlet of the first light phase discharge.
