    Procedure for the treatment of cork. It involves eliminating or extracting organic compounds (specifically tricloroanisole 2-4-6) from the cork intended to manufacture caps for wine bottles. The crushed cork, according to the method of the invention, is subjected to a fluidization process in a chamber (2), or in several chambers (2 '), (2' '), (2' ''), and a humidification process in a chamber (5) or in several chambers (5 '), (5' '), (5' ''), each one of them arranged next to each of the fluidization chambers, all of so that the cork reduces the percentage of trichloroanisole 2-4-6 until it reaches a value of, for example, 0.01 nanograms per liter, at which time the cork is passed from the last humidification chamber to a collection tank (7) for storage of treated corks, one or more inert gases being able to be applied together with the corresponding vapor in the fluidization process.

    DESCRIPTION
    Procedure for the treatment of cork.

    OBJECT OF THE INVENTION 5

    The present invention relates to a process for the treatment of cork, and more specifically to a process for treating and extracting certain organic compounds, preferably trichloroanisole 2-4-6, to obtain a cork suitable for the manufacture of stoppers intended for closure or covered with bottles intended to contain wine. 10

    The procedure is based on subjecting the crushed cork to a fluidization process followed by a humidification process, in which trichloroanisole 2-4-6 is removed.
    BACKGROUND OF THE INVENTION 15

    As is known, cork is a material that is used, among other applications to manufacture caps for the closure of bottles, specifically wine bottles, and all this as a result of the special characteristics of this material, such as elasticity, flexibility, compression, impermeability, etc. twenty

    Now, when the cork is in contact with the wine when it corks a bottle, it can lead to the production of odors due to certain microorganisms, so that the cork before the cap is manufactured, or after the bottle is manufactured, and before If applied at the closure of the bottle, it is subjected to cleaning treatments to eliminate certain 25 organic compounds.

    In this sense, many systems and procedures for cleaning cork are known, to avoid odors and flavors that could affect the wine contained in the bottle covered with the cork in which organic compounds have originated. 30

    Among such organic compounds, trichloroanisole 2-4-6 stands out, and to remove this compound, the cork or plugs are subjected to cleaning operations, either by chlorine-based washing, or by washing with salic acid, among others, although as The most common procedure for eliminating certain volatile compounds responsible for 35 flavors in corks and specifically in caps, is the use of hot or boiling water, although this is a very rudimentary and inefficient method, there are documents corresponding to patents and even articles which allow the extraction of chloroanisoles, among other organic compounds, in this regard the invention patent with publication number 2216965 can be cited, in which among other 40 organic compounds trichloroanisole is eliminated, the process in this case consisting in submitting the cork at a contact with a dense fluid under pressure, and at a temperature between between 10 and 120 ° C, where the pressure is given or will be between 10 and 600 bar, with a co-solvent being added at a rate of 0.01 to 10% by weight, this fluid being preferably dense carbon dioxide. Four. Five

    In this procedure the dense fluid under pressure is in a supercritical state and in the process pressure / decompression cycles are carried out, allowing the elimination of organic compounds responsible for unwanted flavors and / or odors.
    However, this procedure is complex and therefore of high economic cost in its implementation.
    DESCRIPTION OF THE INVENTION
     5
    The recommended procedure is intended to treat crushed cork and remove or extract trichloroanisole 2-4-6, based on a simple, simple and economical process.

    More specifically, the procedure consists in subjecting the crushed cork to a fluidization process followed by a humidification process, which can be repeated successively until the percentage of trichloroanisole is less than 0.3 nanograms per liter, and more effectively and safe when the percentages of said trichloroanisole are less than 0.01 nanograms per liter or undetectable.

    In short, it is that the crushed cork is passed through a chamber to which steam is applied to effect a fluidization of the cork itself, which is then passed to a humidification chamber, so that the system can have a fluidization chamber and a humidification chamber, or several, until the cork that goes through the same reaches the aforementioned percentages, in which case the treated cork is passed to a collection silo for the subsequent processing of the Cork for the manufacture of caps.

    The steam supply to the chamber or fluidization chambers is carried out from a steam tank and the humidity in the chamber or humidification chambers will also be carried out through a suitably treated water tank. 25

    In addition, one or more types of inert gases, such as nitrogen, helium, argon, ozone, etc., can be applied in the fluidization chamber or chambers.

    The fluidization to which the cork is subjected lowers the humidity and its granulation, 30 since to make plugs it is necessary that said humidity is between 6 and 8% RH.

    An inert gas is added to the hot steam, first in order to assist in cleaning the cork itself, and then also serving to clean deposits inside by emptying them after 35 each day.

    Finally, say that the application of steam to the chamber or fluidization chambers will be carried out at a temperature of approximately 140 to 160 ° C, although this range may vary according to objectives. 40
    DESCRIPTION OF THE DRAWINGS

    In order to complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, it is accompanied as an integral part of said description, of a sheet unique of planes where, for illustrative and non-limiting purposes, the following has been represented:

    The unique figure shown on that sheet of plans corresponds to the scheme of what would be an installation for the implementation of the method object of the invention.
    PREFERRED EMBODIMENT OF THE INVENTION
     5
    As can be seen in the aforementioned figure, the crushed cork is stored in a tank (1), from which it is passed to a fluidization chamber (2) to which steam (3) is applied from a steam producing equipment (4), so that the cork of the tank (1) and passing through the chamber (2), subjected to steam, at a temperature of approximately 150 °, is passed to a humidification chamber (5), at which apply water from a 10 tank (6).

    This process repeats a certain number of extraction cycles, establishing fluidization chambers (2 '), (2' '), (2' '), in series with humidification chambers (5'), (5 '' ), (5 '' '), as shown in the figure, so that in the ducts that each chamber communicates with the next one, three-way valves or keys are provided that allow the treated product to be diverted towards a collection tank (7), with an outlet (9) for the treated cork or redirect the product so that it is subjected to a new process of fluidization and humidification, all depending on the percentage of trichloroanisole removed is less than one preset value. twenty

    It only remains to point out that, in the fluidization processes of the different fluidization chambers (2), (2 '), (2' '), (2' ''), inert gases from different reservoirs can also be applied ( 8), (8 '), (8' '), which collaborate in a better cleaning of the cork itself and the process. 25
