A method for reducing TCA in all forms of natural cork-type cork products such as technical stoppers, discs for stopper, boiled and raw cork plank, wherein after introducing the corks into a device such as the one defined in the preceding claim, the method is characterized in that it comprises the following steps: - an initial step of at least one hot air generator causing the entry of hot air into a chamber at a temperature comprised between 175°C and 185°C, so the temperature inside the chamber starts to rise gradually and the molecules of the cork products start to move, expanding the body of each of the products; then, - in a step of causing the entry of supersaturated dry steam, a temperature sensor of the chamber itself activates at least one steam boiler when the temperature inside the chamber reaches 85°C, initiating the injection of supersaturated dry steam at a temperature comprised between 125°C and 135°C into the chamber the moving TCA molecules of the cork products therefore combine with the molecules of the supersaturated dry steam; along with this step of causing the entry of supersaturated dry steam, - an electric extractor initiates an electrical air extraction step, whereby the supersaturated dry steam being injected into the chamber , after contact thereof with the cork products, is rapidly discharged out of the chamber through a continuous ventilation flow created inside the chamber , between a natural ventilation of the chamber and the electrical air extraction brought about by the electric extractor ; and subsequently, - in a last step involving an optimum process temperature, while extraction is taking place and the temperature inside the chamber is increasing due to the continuous entry of the hot air and the supersaturated dry steam, a temperature sensor activates at a temperature comprised between 100°C and 130°C a drop in temperature at the hot air inlet for the entry of hot air from the generator to the chamber , such that the temperature inside the chamber is kept constant at a temperature between 100°C and 110°C during the TCA molecule extraction process. - an initial step of at least one hot air generator causing the entry of hot air into a chamber at a temperature comprised between 175°C and 185°C, so the temperature inside the chamber starts to rise gradually and the molecules of the cork products start to move, expanding the body of each of the products; then, - in a step of causing the entry of supersaturated dry steam, a temperature sensor of the chamber itself activates at least one steam boiler when the temperature inside the chamber reaches 85°C, initiating the injection of supersaturated dry steam at a temperature comprised between 125°C and 135°C into the chamber the moving TCA molecules of the cork products therefore combine with the molecules of the supersaturated dry steam; along with this step of causing the entry of supersaturated dry steam, - an electric extractor initiates an electrical air extraction step, whereby the supersaturated dry steam being injected into the chamber , after contact thereof with the cork products, is rapidly discharged out of the chamber through a continuous ventilation flow created inside the chamber , between a natural ventilation of the chamber and the electrical air extraction brought about by the electric extractor ; and subsequently, - in a last step involving an optimum process temperature, while extraction is taking place and the temperature inside the chamber is increasing due to the continuous entry of the hot air and the supersaturated dry steam, a temperature sensor activates at a temperature comprised between 100°C and 130°C a drop in temperature at the hot air inlet for the entry of hot air from the generator to the chamber , such that the temperature inside the chamber is kept constant at a temperature between 100°C and 110°C during the TCA molecule extraction process. <EOS>
