METHOD FOR STRIPPING AND SANITIZING A CONTAINER INNER SURFACE AND IMPLEMENTING DEVICE

摘要

The invention concerns a method for stripping and sanitizing a container (14) inner surface presenting a layer of organic and/or mineral deposit, in particular tannin resulting from winemaking in cask. The invention is characterised in that it consists in applying on the surface to be treated a pulsed radiation (4) produced by an intense optical source (1), each pulse being of sufficiently short duration having sufficiently high treating energy density per unit area to bring about sublimation of said surface deposit, the resulting exposed container surface being sanitized by the heat released by the radiation. The invention also concerns a device for implementing said method.
