摘要:
The invention provides a process and an apparatus for scrubbing vapours generated during the vacuum stripping step of fatty glycerides, said process comprising bringing said vapours in contact with their liquid condensate and extracting said liquid condensate with a polar extraction solvent or solvent mixture.
摘要:
Vacuum stripping process as used in the physical refining and deodorisation of edible oils, comprising at least a first stripping vessel (2) being supplied with material to be vacuum stripped and also being supplied with stripping medium by a single pump (5) that obtains this stripping medium from a further downstream second stripping vessel (3) which is equipped with two or more trays (12), (13), (14) or (15), over which the partially stripped material coming from the first stripping vessel (2) is directed, characterised in that the partially stripped material on these trays (12), (13), (14) or (15) is sparged with fresh stripping medium and said stripping medium is collected from above each tray (12), (13). (14) or (15) of the second stripping vessel (3) by means of said pump (5).
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.
摘要:
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.
摘要:
A process for recuperating a triglyceride oil from wet gums from a vegetable oil, comprising the steps of:
(a) providing wet gums by water de-gumming a crude vegetable oil, (b) mixing said wet gums with water containing a phospho-lipidolytic agent, (c) allowing the mixture to separate into two or more phases, said two or more phases including at least an oily phase and an aqueous phase, and (d) recuperating the said oily phase.
