    [0004] Object of the invention.
    [0005]
    [0006] The present invention relates to a method and equipment for the discovery of the harvest by the injection of air or other gases under controlled pressure in self-emptying wine tanks or similar in order to carry out the emptying of the harvest. Once the maceration has finished.
    [0007]
    [0008] In particular, the invention relates to the transfer of the liquid fraction to another tank and the grape pulp squeezed into the press using a method and equipment based on pressurized injection of air or other gases in a controlled manner into tanks. of self-emptying vinification in order to homogenize the mixture before the discovery, facilitating said operation.
    [0009]
    [0010] Description of the state of the art.
    [0011]
    [0012] Maceration means the extraction process involving two phases: a solid phase and a liquid phase. The solid product has a series of compounds, which are those that are intended to be extracted, soluble in the extractant liquid. In the production of red wine, the skin or grape skin (solid product) contains polyphenolic and aromatic compounds (which you want to extract to endow the final product with more intensity of color and aromas). During the maceration, these compounds are solubilized in the liquid (first must and then came).
    [0013]
    [0014] Once the maceration process has been completed, attaining the density value that the winemaker considers adequate, the auotovaciante deposit of the winemaking, an operation called discover, is emptied. For this, the usual existing procedure consists in extracting first the liquid fraction, an operation usually referred to as bleeding from the harvest, and then proceeding to extract all the dry solid part.
    [0015]
    [0016] To do this, the tank, inside and in the lower part thereof, is provided with grids that act as a sieve; so that they allow the passage of liquid to through one of its mouths in which it has placed on the outside a conduit that will direct the liquid to a portable cellar pump that will propel it to a second deposit where it will be stored.
    [0017]
    [0018] Once the liquid has been extracted, the solid phase or dry paste is removed. To this end, a door is opened in the lower part of the tank, with a larger section equipped with a guillotine and called the mouth of pasta. In this way, the paste falls, due to gravity, in an open pipe provided with an endless screw or, failing that, towards an opening drawer. These elements allow to take the paste to the press where it is subjected to a more forceful draining action.
    [0019]
    [0020] It is usual that the whole pasta does not dislodge the deposit simply by the aforementioned effect of gravity, so it is necessary the intervention of an operator who, entering the tank must push / drag this paste to the mouth of pasta for its total evacuation. Unwanted task by the winemaker.
    [0021]
    [0022] With the usual procedure described, the discovery of the harvest of a 100,000 liter tank takes approximately 4 hours.
    [0023]
    [0024] To alleviate this problem to some extent, it is common to use self-emptying tanks that incorporate agitators to homogenize the liquid and solid phases of the harvest before the discovery. These agitators are bulky devices that reduce the capacity of the tanks, require complex maintenance and are expensive. The use of agitators facilitates the dragging of the solid towards the exit or its mixing with the liquid phase, but it still requires the intervention of operators since the homogenization that is achieved is not total, leaving remains of pastes whose removal must, again, be carried out , pushing / dragging said remains of pasta to the mouth of pasta for its total evacuation.
    [0025]
    [0026] The above-mentioned problems are solved by a method and equipment according to the invention, for the discovery of the harvest by means of pressure injection of air or other gases in a controlled manner in self-emptying wine tanks or similar in order to carry out the emptying of the vintage once the maceration of the same is finished, in which by means of the injection at air pressure the mixture is homogenized perfectly before the discovery.
    [0027] Description of the invention.
    [0028]
    [0029] The present invention provides a method and equipment for the discovery of the harvest by the injection of air or other gases under controlled pressure in self-emptying wine tanks or similar in order to carry out the emptying of the harvest once completed the maceration of the same, in which by means of the injection at pressure of air the mixture is homogenized perfectly before the discovery.
    [0030]
    [0031] Another object of the present invention is to overcome the problems existing in the prior art.
    [0032]
    [0033] Other objects and additional advantages of the present invention are derived from the description made below, taking into consideration the figures included and the preferred embodiments described by way of example but not limiting.
    [0034]
    [0035] The injections can be of pressurized air or of any other gas that is functionally equivalent and can be used alternatively. In particular, said injections can be of nitrogen or other inert gases.
    [0036]
    [0037] The procedure and equipment for the discovery of the harvest by means of the injection of air pressure is based on the injection of air through the lower part of the frustoconical bottom of the tank. Once the maceration process has been completed, once the density value that the winemaker considers adequate has been reached, the wine self-emptying tank is emptied. To do this, in order to homogenize the contents of the tank, pressurized air is continuously injected for 10-20 minutes, depending on the volume of pasta generated in the tank, depending on the grape variety and the degree of maturity of the same
    [0038]
    [0039] After that time, the liquid and solid phases of the harvest are perfectly homogenized, so the harvest can be removed through one of the conventional mouths of the tank, generally the lower mouth, making its extraction by pumping, using pumps. discover portable or fixed. During the discovery and to continue facilitating the homogenization of the mixture, air injections are maintained until the end of it.
    [0040] The pumping will drive the harvest to a sieve, where the harvest is drained, sending the liquid part to a storage and the solid part drained to a press, where a liquid fraction sent to storage is recovered, usually with the liquid part previously obtained in the discovery and a solid fraction obtained (marc) that can be used to obtain related products.
    [0041]
    [0042] Generally, the injection of air through the bottom of the frustoconical bottom of the tank is carried out through at least one diffuser or compressed air injector installed in the lower part of said tank.
    [0043]
    [0044] Advantageously, the operating time of the de-gassing system can be controlled by a PC-type microprocessor, PLC or the like, in which the values of the times are fixed or can be varied by the user of the pumping system.
    [0045]
    [0046] Likewise, another additional feature of the method and the equipment according to the invention is the inclusion of a system for cleaning the interior of the at least one diffuser which, once the tank is emptied, remains filled with liquid and / or crushed grape paste. inside it, under certain conditions, can degrade quickly giving rise to putrefaction and unwanted substances. For this the procedure is complemented with an injection of water inside the at least one diffuser that drags the remains of the wine from the interior of the at least one diffuser, cleaning said interior. Then, compressed air is again injected, which dries at least one diffuser, eliminating the remains of water. In a preferred embodiment, said water injection is carried out through the compressed air distribution circuit of the equipment and, in a still more preferred embodiment, a water inlet is provided in the compressed air line.
    [0047]
    [0048] Advantageously, the action of the de-aeration system is carried out with a pressure of the air system under pressure comprised between 3 and 6 bar in order to guarantee the effective operation of the opening and closing valve that allows the passage of air.
    [0049]
    [0050] The compressed air used in the dewatering system must be free of impurities such as moisture, oils and particles in suspension, whereby purified air (for food use) can be used directly or the process according to the invention can include a step of purifying the air.
    [0051] When gas supplied by compressor is used, the equipment will include filters at the outlet of said compressor to eliminate moisture, oils and suspended particles from the compressed air.
    [0052]
    [0053] Both the method and the equipment according to the invention can be controlled by means of a PC-type microprocessor, PLC or the like, which carries out all the operations in an automated way starting from predetermined values or selected by the user.
    [0054]
    [0055] The inventive system according to the invention can be an independent system as described or can be integrated as a further step of a method for the pressurized injection of air or other gases in a controlled manner into wine tanks or the like in order to carry out the extraction of the polyphenolic and aromatic compounds through the process of overcoming the harvest during the maceration of the same. In this case, the equipment will include, together with the overflow diffusers, the at least one diffuser that will be installed in the same compressed air distribution circuit and can be controlled through a common microprocessor.
    [0056]
