Abstract

The invention relates to a method of solid-liquid extraction applied to cork products for the decontamination thereof, comprising the following steps:
  • a. Introduction of the cork product in a airtight recipient,
  • b. Filling the airtight recipient with an appropriated decontamination liquid so that the cork product is completely immersed in that liquid,
  • c. Applying a relative pressure of 0 to 10 bar on the liquid surface, for a time period of 1 to 3600 seconds, using an appropriated gas,
  • d. Release of the pressurising gas until the pressure within the recipient reaches atmospheric pressure,
  • e. Reduction of the pressure within the recipient, by means of an appropriated vacuum pump, until a relative pressure of 0 bar to - 1 bar is reached, during a time period of 1 to 3600 seconds,
  • f. Returning the recipient to atmospheric pressure.
