Title
(EN) METHOD FOR DIRECT TREATMENT OF CORK STOPPERS, USING SUPERCRITICAL FLUIDS
(FR) PROCÉDÉ POUR LE TRAITEMENT DIRECT DE BOUCHONS DE LIÈGE AU MOYEN DE FLUIDES SUPERCRITIQUES
Abstract
(EN)
This invention describes a method which permits direct treatment of natural cork stoppers, using supercritical fluids with the aim to eliminate or significantly reduce the quantity of cork contaminants, namely 2, 4, 6-trichloroanisole. The process uses a separating device which permits natural cork stoppers to go through compression/decompression cycles without losing their shape and maintaining their sealing properties. This invention refers also to the natural cork stoppers treated by this method.
(FR)
La présente invention concerne un procédé qui permet un traitement direct des bouchons en liège naturel, au moyen de fluides supercritiques, de façon à éliminer ou réduire de façon notable la quantité de contaminants du liège, en l'occurrence le 2,4,6-trichloroanisole. Le procédé met en œuvre un dispositif séparateur qui permet aux bouchons en liège naturel de subir des cycles de compression et décompression sans perdre leur forme et en conservant leurs propriétés d'étanchéité. L'invention concerne également les bouchons en liège naturel traités selon ce procédé.
