    [0001] DEVICE AND PROCEDURE FOR REDUCTION OF TCA
    [0002]
    [0003]
    [0004]
    [0005] OBJECT OF THE INVENTION
    [0006]
    [0007] The invention is intended to reduce the levels of TCA or trichloroanisole molecules present in some types of corks, so that sensually the smell and taste that products containing this type of molecules give off are invaluable to an expert or user in general. For this, the cork products to be treated are introduced into a cabin that is part of the device of the invention, such that after the application of a procedure through a series of stages associated with the device, each of the treated products experiences a substantial reduction in their TCA levels, without this causing deterioration or deformation in cork products, even when subjected to high air temperatures, supersaturated dry steam and pressure during their process.
    [0008]
    [0009] The device for the reduction of TCA in cork products object of the present invention comprises at least one hot air generator, a supersaturated dry steam boiler and an electric extractor; all connected by tubes or similar to a cabin that has at least one natural ventilation outlet and temperature sensors; and that the associated procedure for the reduction of TCA in cork products comprises an initial hot air inlet stage, then a supersaturated dry steam inlet stage, simultaneously an electric air extraction stage is initiated and finally a stage Optimum temperature of the TCA reduction process in cork products.
    [0010] The field of application of the invention is within the cork industry, specifically for the treatment of natural cork, technical cork stoppers, cork discs or the like.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] Trichloroanisole or TCA is a substance that results from the degradation of trichlorophenols, which in turn come from the union of cork phenols with chlorine particles dissolved in the air. This degradation usually takes place in humid environments and is caused by a series of fungi. The problem of TCA or tricloanisole molecules present in some types of cork used in bottles intended for wines or the like, is responsible for the wines having a smell commonly defined as cork flavor. This defect being one of the most commonly widespread problems worldwide, since once the TCA molecules invade a wine it is impossible to eliminate it, in fact if it is in high proportions it is reason for rejection by the consumer.
    [0015]
    [0016] The sensory thresholds of TCA vary between each user or expert taster, which in the case of professional wine tasters judges the quality and characteristics of a wine after being bottled by means of their senses, which expresses their perceptions according to their personal criteria For all this and regardless of the quality of the wine, if the cork stopper that covers it transmits TCA molecules, these will be noticed in the taste and smell of the wine, so this problem is one of the most persecuted by winemakers
    [0017]
    [0018] According to the foregoing, different registers are released from the state of the art that seek to reduce the levels of trichloroanisole or TCA, using for this purpose subjecting the cork stoppers to different conditions of temperature, pressure or external exposures. Fact that is reflected in the records that we accompany below.
    [0019] In the case of the ES2247180T3 patent, a process is disclosed by which the extraction of the TCA particles from the cork stoppers is produced by a gas phase process formed by ethanol vapor, water vapor and air at a temperature between [25 ° and 100 °] C and a pressure between [0.01 and 2] bar. The problem presented by this record, as evidenced by the results obtained experimentally in the tests of the registry itself, is that at temperatures of 70 ° C irreversible distortions of the plug are observed, after cooling. On the contrary, in the case of the present invention the optimum temperature to which the cork stoppers are subjected inside the cabin is 110 ° C or more, by means of hot air and supersaturated dry steam, without producing on the cork stoppers. deformations
    [0020]
    [0021] Another example belonging to the state of the art is the registration of the patent ES2268459T3, in which a process based on the treatment of granules and cork stoppers by the extraction of TCA compounds entrained in water vapor is disclosed. In this register, there are two types of apparatus for cork granules and for cork stoppers, different from the configuration presented by the device of the present invention; and also, as indicated in the aforementioned register, the cork stoppers used in their process if they are subjected to the same values as the cork granules, that is to say temperatures between [100 ° and 125 °] C and a pressure standard of [0.2 and 0.8] bar, these plugs would present deformations in their structure. Therefore, we can say that this register reduces the levels of TCA of the cork stoppers, differently from that presented in the device and method of the present invention. Since the conditions to which the cork stoppers are subjected in the present invention are by using hot air and supersaturated dry steam, such that the optimum internal temperature conditions within the cabin containing the plugs is of 110 ° C or more, with a continuous flow of ventilation, without producing deformations in them.
    [0022] In the registration of the patent ES2402890T3 a procedure is disclosed that allows the application of the direct treatment of cork stoppers with supercritical fluids in a high pressure vessel using a separation device, the contraction and expansion of the cork stoppers for TCA reduction. On the contrary, in the device and method of the invention, supersaturated steam and hot air are used for the reduction of TCA molecules in temperature and pressure values within a given cabin, which has nothing to do with those disclosed in said patent.
    [0023]
    [0024] Finally, we highlight from the state of the art the registration of patent ES2019562 in which water vapor is used to deodorize the cork, in this register the cork pieces to be treated are of a relatively small predetermined size, which are introduced in a vessel with pressurized water vapor, to be subsequently cooled. On the contrary, with the device and method of the invention, regardless of the size of the cork products to be treated, these are subjected to stages of hot air and supersaturated steam with a continuous flow of extraction of both means, so that it is achieved considerably extract TCA molecules instantly at the entrance of the supersaturated dry steam.
    [0025]
    [0026] Therefore, with the device and procedure for the reduction of TCA in cork products object of the present invention, a further step is taken in the cork sector, since the natural cork stoppers in all their measures, the technical plugs , the stopper discs, the cork in raw and boiled iron or similar, can be subjected to temperatures with hot air and supersaturated dry steam greater than 85 ° C without deforming the cork or losing its properties, as it has been happening Until now. In such a way that when a cork product is introduced inside the device of the invention, it experiences a series of stages produced in addition by a continuous current of ventilation, which allows to reduce the particles of TCA more efficiently and differently from what is known. So far in the corchero sector.
    [0027] Below is a detailed description of the invention that completes these general ideas introduced at this point.
    [0028]
    [0029] DESCRIPTION OF THE INVENTION
    [0030]
    [0031] The device for the reduction of TCA in cork products object of the present invention, comprises a cabin that has at least one non-forced ventilation outlet, and which is connected by pipes or similar at least one hot air generator, a boiler of supersaturated steam and an electric extractor, so that when different batches of cork products are located inside, these are subjected to different temperature stages by hot air and dry steam, by which the TCA particles are extracted to the exterior of the cabin, thus decreasing the level of TCA particles in each of the products.
    [0032]
    [0033] The cabin comprising the device has dimensions such that it allows inside a multitude of metal containers or lattice containers in which cork products are introduced, preferably natural cork stoppers in all their measures, technical plugs, disks for plug, raw and boiled iron cork, and even cork granules. At a lower point of one of the walls or sides of the cabin, preferably on the side opposite the door, there is at least one non-forced ventilation outlet. This ventilation is located at a lower point in order that the coldest air inside the cabin will naturally come out, once it has its doors closed, as explained later in this document.
    [0034]
    [0035] Connected by pipes or similar to the cabin there is at least one hot air generator, preferably two the number of generators connected to the same. The hot air inlet or inlets inside the cabin are preferably located at two points, which cover the entire cabin in a low area, but above the natural ventilation outlet. The hot air generator introduces into the interior the air at a temperature set between [175 ° and 185 °] C, a nominal thermal flow at 103.2 KW, a thermal power of 93 KW and an air flow between [1,500 and 2,000] m3 / h. Being the optimum temperature of hot air inlet to the cabin of 180 ° C.
    [0036]
    [0037] Linearly above the heat inlets is the supersaturated dry steam inlet, that is, the inlet of the supersaturated steam into the interior of the cabin is carried out by the linear arrangement of perforated pipes along two opposite walls of the cabin. The height at which these steam pipes are arranged is above the hot air inlets of the generator. The steam boiler introduces the supersaturated steam inside the cabin at a temperature between [125 ° and 135 ° C], a volume of 0.12m3, a pressure between [4 and 8] bar, a flow of 140 K / h, said generator being type 1 and category C. The optimum inlet temperature of dry steam is supersaturated to the cabin of 130 ° C.
    [0038]
    [0039] Another detail of the device of the invention is that on the upper central part of the cabin there is a forced air outlet that is made by means of a tube with an electric extractor, such that through the said extractor, the TCA particles that they have adhered to the supersaturated dry steam inside the cabin, as indicated later in one of the stages of the procedure, they are expelled outside along with the hot air. For all these reasons, a continuous flow of air produced by the natural ventilation outlet and the aforementioned electrical extraction is created inside the passenger compartment.
    [0040]
    [0041] The associated procedure for the reduction of TCA in cork products of the invention comprises an initial stage of hot air inlet, then a supersaturated dry steam inlet stage, simultaneously an electric air extraction stage and finally an optimum temperature stage of the TCA reduction process in cork products are started.
    [0042]
    [0043] Once the cork products to be treated are located inside the enclosed compartment of the device of the invention, these products being preferably introduced in batches in different metal lattice containers, the first stage of the procedure corresponding to the entry of hot air begins. In this stage, hot air is introduced into a previously closed cabin, at a temperature set between [175 ° and 185 °] C by means of at least one hot air generator, preferably two the number of process generators located in different zones. By applying the hot air, the temperature inside the cabin begins to rise gradually and therefore the cork products at this stage begin to heat up, so that the particles that make up each of the cork products begin to expand by the action of the air that begins to move its particles faster, since these particles need more space to move, causing a small increase in body size. At this point it is considered convenient to note that the TCA particles containing the different cork products to be treated are housed between the particles of the cork body.
    [0044]
    [0045] As mentioned above, the interior temperature of the cabin rises gradually as the hot air enters, standing out through a natural ventilation outlet that the cabin has at a lower point, the colder air comes out gradually outside. When the temperature reached inside the cabin is at least 80 ° C, the optimum temperature being 85 ° C, a temperature sensor that has the cabin itself activates at least one steam boiler, preferably a boiler being the optimum number, starting the inlet stage of supersaturated dry steam. This operation can be done manually.
    [0046] In this dry steam inlet stage, dry steam is injected into the cabin at a temperature between [125 ° and 135 °] C. This action causes cork products that TCA particles that are in motion, together with the own particles of each one of the products, link with the supersaturated dry steam. That is why, simultaneously with the actuation of this stage, a stage of superior electrical extraction of air is initiated by means of an electric extractor. Thus, at the same time that the referred temperature sensor drives the steam generator, the electric extractor also operates. These functions can also be performed manually.
    [0047]
    [0048] At this stage of air extraction, the saturated dry steam that is being injected inside the cabin and that due to its molecular configuration links with the TCA molecules, is quickly evacuated to the outside of the cabin through the continuous flow of ventilation created in the interior of the cabin, between the previously mentioned natural ventilation and the electric extraction of air. Then, while the TCA molecules are extracted from each of the cork products, the temperature inside the cabin gradually increases by the continuous entry of hot air and supersaturated dry steam, that is why when the temperature inside it between [100 ° and 130 °] C a temperature sensor activates the gradual lowering of the generator hot air temperature, beginning the last stage of the process of the invention corresponding to the optimum temperature. This operation can also be manual.
    [0049]
    [0050] In this last stage, the temperature of the generator begins to fall, preferably in 10 ° C intervals, until the temperature inside the cabin is kept constant between [100 ° and 110 °] C, setting the temperature of 110 as optimal ° C, inside the passenger compartment, so that the continuous extraction of dry steam supersaturated with TCA molecules is optimal, although this temperature may be higher as long as it does not affect the internal structure or the properties of the cork, being able to reach 130 ° C, provided that it does not produce the aforementioned deformations.
    [0051]
    [0052] It is emphasized that the operation of the treatment is feasible with both static and moving products.
    [0053]
    [0054] In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting nature:
