Definitions

  • the invention relates to the decontamination of cork products by means of a solid-liquid extraction method based on the successive application of pressure changes on a liquid surface in which the cork is immersed, which causes cork contraction and expansion, thereby causing the release of contaminants entrapped within the cork.
  • cork is a natural porous product that contains in its surface, and within it, a variety of contaminants derived from its life experience in the forest which, when in contact with liquids, can cause organoleptic changes in those liquids.
  • a relative pressure ranging from 0 to 10 bar is applied on the surface of the liquid, for 1 to 3600 seconds, using any kind of gas or gas mixture. Then, the gas is released until the recipient pressure reaches the atmospheric pressure again. Thereafter the pressure is reduced by means of an appropriate vacuum pump until a relative pressure of 0 to -1 bar is reached. After being under this reduced pressure for 1 to 3600 seconds the system is caused to return to the atmospheric pressure.
