Abstract
Methods and apparatus are described for the production of a crystal slurry during the crystallization step of fractionation processes of edible oils and fats and related oil derivatives. The crystallization process for edible oil and fats is carried out in a crystallizer with stationary heat exchange elements, wherein the contents of said crystallizer are made to move along said heat exchange elements in an oscillatory manner without the use of an internal agitator. The crystallizer for edible oil and fats with stationary heat exchange elements is also described.

A crystallization process for edible oil and fats and related derivatives carried out in a crystallizer with stationary heat exchange elements, wherein edible oil and fat contents of said crystallizer are made to move along said elements in an oscillatory manner without the use of an internal agitator.
A dry fractionation process for edible oils and fats, in which a crystal slurry produced according to a crystallization process for edible oil and fats and related derivatives carried out in a crystallizer with stationary heat exchange elements, wherein edible oil and fat contents of said crystallizer are made to move along said elements in an oscillatory manner without the use of an internal agitator is separated into an olein fraction and a stearin fraction.
A crystallizer for edible oil and fats and related derivatives with stationary heat exchange elements, comprising means to move edible oil and fat contents of said crystallizer in an oscillatory manner along said elements in an oscillatory manner without the use of an internal agitator.
