Abstract

The present invention relates to the cleaning or stripping of coated objects. The coating is dissolved in a receiver tank rendered inert by means of nitrogen, by a solvent and the mixture of solvent and coating product is transferred into a thickening tank swamped by a heated nitrogen flow. The nitrogen-solvent mixture is separated by cooling and condensation of the solvents extracted. The invention is applied to the stripping of objects coated with paints and varnish.
