(EN) TRANSESTERIFICATION PROCESS
(FR) PROCEDE DE TRANSESTERIFICATION
Abstract
(EN)
The invention relates to a process and a device for the preparation of a sterol and/or stanol fatty acid ester by a continuous transesterification process. The process comprises providing a dried feed mixture comprising a sterol and/or stanol (1) and an alkyl fatty acid ester (2), adding a transesterification catalyst (3) to the dried feed mixture to obtain a reaction mixture, continuously feeding the reaction mixture into a thin film evaporator (7) where the transesterification reaction takes place, continuously withdrawing alkanol (8) formed during the reaction from the thin film evaporator, and continuously recovering a sterol and/or stanol fatty acid ester product from the thin film evaporator, and removing (9) catalyst from the recovered product, and optionally refining (10) the recovered product.
(FR)
L'invention concerne un procédé et un dispositif servant à la préparation d'un ester d'acide gras de stérol et/ou de stanol par un processus de transestérification continue. Ce procédé consiste : à obtenir un mélange de charge séché contenant un stérol et/ou un stanol (1) et un ester d'acide gras d'alkyle (2) ; à ajouter un catalyseur de transestérification (3) au mélange de charge séché pour obtenir un mélange de réaction ; à acheminer de façon continue le mélange de réaction dans un évaporateur à couche mince (7) dans lequel se produit la réaction de transestérification ; à retirer de façon continue de l'évaporateur l'alkanol (8) formé pendant la réaction ; à récupérer de façon continue de l'évaporateur à couche mince un produit ester d'acide gras de stérol et/ou stanol ; à éliminer (9) le catalyseur du produit récupéré ; et à raffiner (10) facultativement le produit récupéré.
