    CORK CLEANING SYSTEM FOR THE ELIMINATION OF HALOANISOLS AND HALOPHENOLS D E S C R I P C I O N OBJECT OF THE INVENTION
    The present invention relates to a cork cleaning system for the elimination of haloanisols and halophenols that allows heating the cork and achieving vacuum pressures of the
    10 order of 10-6 mbar.
    The object of the invention is a cork cleaning system for the elimination of haloanisols and halophenols comprising a set of metal tubes inside which the cork is arranged, where the metal tubes are perforated and are located
    15 surrounded by conduction heating means, so that heat is transferred to the perforated metal tubes and from there to the cork. In addition, the system comprises high vacuum pumps uniformly distributed along the perforated metal tubes, which facilitates the transmission of a high vacuum pressure to the entire cork arranged inside the perforated metal tubes. BACKGROUND OF THE INVENTION
    Cork cleaning systems for the elimination of haloanisols and halophenols comprising a reservoir where the cork is placed are known in the prior art.
    25 treat and a vacuum application device that is connected to the reservoir for the application of vacuum pressure.
    Among the above is the Spanish patent ES2423255B1 relating to an installation for carrying out a procedure for the elimination of haloanisols and halophenols
    30 present in the cork comprising a stage of thermal desorption in the gaseous state of the haloanisols and halophenols present in the cork by applying a vacuum pressure, where the installation comprises a tank where the cork to be treated is placed and a device for vacuum application that is connected to the tank for the application of vacuum pressure.


    The installation tank is thermally insulated and in turn comprises a cork heating device, which is preferably a heat exchanger.
    The French patent FR2884750A1 is also known relating to a device for decontamination of cork stoppers by removing halogenated compounds derived from anisole, preferably 2,4,6-trichloroanisole (TCA).
    These haloanisols are very polluting, capable of ruining the properties
    10 organoleptic of any liquid, producing unpleasant odors and flavors, which we could call fungal or moldy. This is very possibly due to its high volatility. Its threshold of olfactory and gustatory perception is very low, so that a very small amount is already perceived through taste or smell. In the case of TCA, 1.5-3 ng / l of said compound in an alcoholic solution such as wine, is sufficient to
    15 be detected.
    In the device of the previous patent, the cork stoppers placed in a large tank are heated by procedures such as infrared radiation, microwaves, etc. that do propagate energy through vacuum, but they are very energetic methods, so they do not allow a
    20 uniform heating of the cork stopper and cause deformations in it.
    To avoid these inconveniences, in said patent the agitation of the plugs is resorted to by various procedures such as a fixed vat with an internal rotary stirrer, or a rotating vat. These devices have vacuum loss problems, which are more
    25 relevant when working with high vacuum pressures.
    The cork cleaning system for elimination of haloanisols and halophenols of the present invention allows to solve all the above drawbacks. 30 DESCRIPTION OF THE INVENTION
    The present invention relates to a cork cleaning system for the elimination of haloanisols and halophenols comprising:


    - a set of metal tubes inside which the cork is arranged, where the metal tubes are perforated;
    - conduction heating means surrounding the metal tubes
    perforated to transfer heat to the cork arranged inside the perforated metal tubes 5;
    - vacuum means uniformly distributed along the perforated metal tubes for the transmission of a high vacuum pressure to the cork disposed inside the perforated metal tubes.
    The system further comprises a housing in which the set of perforated metal tubes and the conduction heating means are arranged.
    Optionally, the housing also comprises at least one gate for insertion and / or exit of the cork inside the perforated metal tubes.
    In this way, the cork cleaning system for the elimination of haloanisols and halophenols of the present invention heats and applies high vacuum evenly to the cork and does not have moving parts, which prevents the loss of vacuum pressure caused for example by Rotary joints present in installations with moving parts.
    The cork cleaning system for the elimination of haloanisols and halophenols of the present invention is suitable for carrying out the process of elimination of haloanisols and halophenols present in the cork of the Spanish patent ES2423255B1 which is included herein by reference.
    25 Laboratory tests have shown that the effectiveness of the Spanish patent procedure ES2423255B1 improves when the temperature is high and the vacuum associated with a vacuum pressure is large.
    30 The use of high temperatures is limited by the stability of the cork structure, so that temperatures above 160ºC are not recommended.
    The vacuum does not affect the stability of the cork structure, so large voids are very useful. The limits are imposed by the size and design of the installation or system


    of cork cleaning and by the type and characteristics of the vacuum pumps used. Voids of the order of 10-6 mbar are very effective.
    Apparently the technological application of this procedure in the form of a cleaning system may seem simple. However, in practice it poses serious difficulties, derived from two important facts:
    a) Cork is one of the best insulators that exist, so it conducts heat very badly and does it slowly. This means that it is very difficult to transfer heat to the
    10 cork and keep it warm evenly. The uniformity of the temperature is fundamental so that the elimination of the contaminants is uniform throughout the cork.
    b) The vacuum, especially the high vacuum, is another perfect insulator, so that it is a medium that does not allow heat to be transmitted by conduction or convection.
    15 On the other hand, when it comes to achieving high vacuum conditions, the design of the system is very important especially to achieve the same vacuum in each and every point of the system, so that all the cork elements are subjected to the same vacuum.
    20 The different position of the cork element in the system in relation to the vacuum means, the proximity of other cork elements, etc ... are sufficient for very significant differences in the vacuum. Keep in mind that the spread of the high vacuum from the vacuum media that originate it to the points to which it should
    The transmission of the vacuum pressure further away from said vacuum means, or more inaccessible, will create a very high vacuum gradient.
    All these considerations lead to having to solve two important problems:
    30 a) How to heat and keep the temperature uniform in all cork elements under high vacuum conditions. b) How to design the system so that there are no gradients in the vacuum and all the cork elements are subjected to the same vacuum.


    The cork cleaning system for the elimination of haloanisols and halophenols of the present invention described in this section solves all the above problems. DESCRIPTION OF THE DRAWINGS

    15 of the second set of metal tubes are aluminum, copper, brass or stainless steel and its inner diameter is in the range 2 to 12 mm.
    The housing comprises two gates (6) for insertion and / or exit of the cork, preferably in the form of cork stoppers inside the metal tubes
    20 perforated (1).
    Optionally, the system comprises a third set of metal tubes (not shown), where the metal tubes are not perforated and have the same diameter as the metal tubes of the first set of perforated metal tubes (1), where the system 25 comprises means of prior heating to heat the third set of metal pipes, where the cork, preferably in the form of plugs, is arranged in said third set of metal pipes previously available in the first set of perforated metal pipes (1), and where The first set of perforated metal tubes (1) and the third set of metallic tubes are connectable. The system
    30 further comprises transfer means, preferably pneumatic or mechanical to transfer the cork, preferably in the form of plugs of the third set of metal tubes to the first set of perforated metal tubes (1).
