CRISTALLISEUR, SYSTÈME DE FRACTIONNEMENT POUR HUILES ET GRAISSES COMESTIBLES ET PROCÉDÉ DE FRACTIONNEMENT D'HUILES ET DE GRAISSES COMESTIBLES

摘要

A crystallizer (4) for edible oils or fats comprising a vessel (6), a rotor (11) rotatably arranged in said vessel (6) rotatable around a vertical rotational axis (x), in which rotor (11) a plurality of axially elongated parallel tubes (12) are arranged at a distance from each other, an inlet (7) at the top of said vessel (6) which inlet (7) is arranged to convey the edible oils or fats into said vessel (6), an outlet (8) at the bottom of said vessel (6) which outlet (8) is arranged to convey a crystal slurry, formed in the vessel (6) from the edible oils or fats, out of said vessel (6), an inlet pipe (9) arranged to convey a cooling medium into said vessel (6) and rotor (11), wherein the inlet pipe (9) is connected to first end openings of said parallel tubes (12) for further conveying said cooling medium into said parallel tubes (12), and an outlet pipe (10) arranged to convey said cooling medium from said rotor (11) out of the vessel (6), wherein the outlet pipe (10) is connected to second end openings of said parallel tubes (12).
