Abstract
Process including the solvent crystallization of edible fatty material into a crystal slurry containing at least solid crystallized stearin dispersed into a solution composed solvent and olein, and further including the separation of the stearin from the solution by applying centrifugal forces onto the crystals slurry.
Claims16
A process for the solvent fractionation of edible fatty materials comprising the steps of:
- a) solubilizing an edible fatty material in a solvent to form a solution,
- b) cooling said solution to obtain a crystal slurry comprising at least two fractions, wherein said at least two fractions is comprised of a solid fraction made of crystals of stearin dispersed in a liquid fraction made of olein dissolved in said solvent,
- c) conducting said crystal slurry in a basket centrifuge,
- d) spinning said basket centrifuge in a way to separate said crystal slurry into said solid fraction and said liquid fraction, said solid fraction forming a stearin cake inside the basket of said basket centrifuge, and said liquid fraction being ejected by centrifugal forces (g-forces) and collected,
- e) optionally washing said stearin cake obtained in step d) with solvent while still spinning the centrifuge,
- f) collecting the stearin cake,
- wherein the temperature of the stearin cake formed in step d) is not increased by more than 5° C. compared to the temperature of the crystal slurry conducted in said centrifuge in step c).
