摘要:
The crystalliser of the invention comprises a crystallisation vessel, an agitator, cooling means and a drive, and is characterised in that said drive provides said agitator with an oscillating motion, a reciprocating motion, and/or a rotating motion around an axis, with the proviso that the various points of said agitator move at substantially the same linear speed when the agitator is provided with a rotating motion around the axis.

The invention relates to a method and installation for the dry fractionation of edible oils and fats and related products, said method comprising the steps of:
a) solidifying the product in a crystalliser comprising at least one cooling chamber that is provided with at least one wall permitting heat transfer, to form a solid block of crystallised material; b) discharging the chambers and collecting the block; c) crushing the block so that a pumpable paste is obtained; d) pumping this paste into a filter press; e) separating this paste into an olein fraction and a stearin fraction by filtration and collecting both fractions.
