Title
(EN) METHOD FOR TREATING WOODEN BARRELS USING A GRIT-BASED AND/OR SLAG-BASED ABRASIVE, AND TREATMENT DEVICE FOR IMPLEMENTING SAME
(FR) PROCÉDÉ DE TRAITEMENT DE FÛTS EN BOIS À L'AIDE D'UN ABRASIF À BASE DE GRENAILLE ET/OU DE SCORIES ET DISPOSITIF DE TRAITEMENT POUR SA MISE EN ŒUVRE
Abstract
(EN)
The invention relates to a method for treating wooden barrels, comprising a step of spraying a grit-based and/or slag-based abrasive onto at least one portion of the inside surface (F10) of a wooden barrel (10) in order to remove a damaged layer (20), and a step of sorting treatment residues resulting from the removal of the damaged layer (20) in order to separate the grit and/or slag from other residues.
(FR)
L'invention a pour objet un procédé de traitement de fûts en bois comprenant une étape de projection d'un abrasif à base de grenaille et/ou de scories contre au moins une partie de la surface intérieure (F10) d'un fût en bois (10) afin de retirer une couche dégradée (20), et une étape de tri de résidus de traitement issus du retrait de la couche dégradée (20) afin de séparer la grenaille et/ou les scories des autres résidus.
