    [0004] Object of the invention.
    [0005]
    [0006] The present invention relates to a method and equipment for the pressurized injection of air or other gases in a controlled manner in winemaking tanks or the like in order to carry out the extraction of the polyphenolic and aromatic compounds by the process of remounting of the vintage during the maceration of it.
    [0007]
    [0008] In particular, the invention relates to the transfer of phenolic and aromatic compounds from the skin to the liquid part (wort) after the grape is crushed using a method and equipment based on the injection of air or other pressures. gases in a controlled way in winemaking tanks.
    [0009]
    [0010] More particularly, the invention relates to the pressurized injection of air or other gases in a controlled manner in winemaking tanks in order to proceed to the efficient breaking of the hat and the provision of the liquid medium of the polyphenolic and aromatic compounds for that are integrated into this liquid medium enhancing the characteristics of the wine.
    [0011]
    [0012] Description of the state of the art.
    [0013]
    [0014] Once the harvest is incubated in the maceration tanks, the release of carbon dioxide bubbles begins, leading to the formation of a dense layer on top of the same, called a hat and composed of skins and pulp, floated by said gas. To achieve the extraction of the polyphenolic and aromatic compounds present in the skins and pulp that constitute said hat, it must be broken in portions so that the liquid comes in contact with the entire solid mass and thus favor this flow of compounds of the fraction solid to liquid.
    [0015] Traditionally, said hat was broken making extractions of liquid phase in the lower part of the vintage deposit with which to soak the hoop until it softens and breaks it.
    [0016]
    [0017] Recently, systems have been developed that allow the breaking of said hat by means of the injection of air or other gases under controlled pressure.
    [0018]
    [0019] The patent AU2004101059 refers to a system of pressurized injection of air in the vintage whose diffusers are placed in the bottom of the tank, all at the same height or same level and they all inject the same amount of air at the same time, generating jets uniforms that reach the hat under the same conditions of pressure and beam opening (see figures 2A and 2B), so the break of said hat is performed inefficiently and, in addition, presents the risk of clogging of the diffusers having its opening mouth directed upwards and placing itself at a level of frequent accumulation of solid waste in the deposits.
    [0020]
    [0021] Patent application WO2016 / 087966A1 discloses a system for injecting air or other gases in a controlled manner, the diffusers of which are all located at the same level in the walls of the tank. The system described in said patent application can not be applied to the bottom of the tank, which limits its application and, as to the method followed, is based on the sequential injection of air into the tank acting on a single point of the hat in each case. moment and with the same amount of air and, therefore, equal conditions of pressure and beam opening in each injection, which is not sufficient at the time of the breakage of said hat and limits the extraction of the polyphenolic and aromatic compounds.
    [0022]
    [0023] To solve the aforementioned problems, the method and equipment for the pressurized injection of air or other gases according to the invention is based on a dual injection with diffusers that inject air two at a time into the tank simultaneously affecting at least two points of the hat during the performance of the system. In addition, the diffusers are located inside the tank at different height or level, so that the pressure and beam opening conditions in each injection are different. In this way, the hat is subjected to a plastic deformation that produces the efficient breakage of said hat and maximizes the extraction of the polyphenolic and aromatic compounds.
    [0024] For the case that the installation of an odd number of diffusers is necessary, the set of them is distributed in groups of two and three diffusers, which can exist in the dual injection system, groups of three diffusers.
    [0025]
    [0026] Likewise, the pressurized injection system for air or other gases in a controlled manner according to the invention can be installed in any type of existing or newly installed tank, minimizing the cost and using the minimum space, taking advantage, whenever possible, of the spaces underutilized, such as, for example, the bottom of the tank in self-emptying tanks or flat bottom with legs.
    [0027]
    [0028] Description of the invention.
    [0029]
    [0030] The present invention provides a method and equipment for the pressurized injection of air or other gases in a controlled manner in winemaking tanks or the like in order to carry out the harvesting process during the maceration of the harvest.
    [0031]
    [0032] Another object of the present invention is to overcome the problems existing in the prior art.
    [0033]
    [0034] 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.
    [0035]
    [0036] 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.
    [0037]
    [0038] Maceration means the extraction process in which two phases are involved: 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 winemaking, the skin or grape skin (solid product) contains polyphenolic and aromatic compounds (which you want to extract to give the final product more intensity of color and aromas). During the maceration, these compounds are solubilized in the liquid (first must and then came).
    [0039] For the purposes of the present description, maceration is divided into the following stages: pre-fermentation maceration, alcoholic fermentation 1 or FAL1, alcoholic fermentation 2 or FAL2 and post-fermentation maceration. Each of said steps is described below:
    [0040]
    [0041] Pre-fermentation maceration: stage of maceration, prior to the generation of alcohol in the medium, which aims to lengthen this process to achieve greater extraction of polyphenolic and aromatic compounds.
    [0042]
    [0043] FAL1 (Alcoholic fermentation 1): first stage of the fermentation process. Begins the transformation of sugar from the must into alcohol. Generally, said process starts with a density of 1.09 g / cm3 and ends when said density drops to 1.04 g / cm3.
    [0044]
    [0045] FAL2 (Alcoholic fermentation 2): transformation of the last sugars of the must into alcohol. Generally, it begins with a density around 1.04 gr / cm3 and ends when said density falls below 0.995 gr / cm3.
    [0046]
    [0047] Post-fermentative maceration: once all the sugars have been transformed into alcohol, the contact of the solid phase with the liquid phase is extended with the same objective of achieving a greater extraction of polyphenolic and aromatic compounds.
    [0048]
    [0049] During the maceration of the grape harvesting operations are applied aimed at activating the maceration of the skins with the must
    [0050]
    [0051] The method and equipment for the pressurized injection of air or other gases in order to carry out the pumping operations according to the invention, is based on a dual injection with means for the injection at pressure of air that inject air, at least , two by two in the tank, striking simultaneously on, at least, two regions of the hat during the performance of the system. In addition, said means for injection at air pressure are placed inside the tank at different height or level, so that the conditions of pressure and beam opening in each injection are different. In this way, the hat is subjected to a plastic deformation that produces the efficient breakage of said hat and maximizes the extraction of the polyphenolic and aromatic compounds.
    [0052] Advantageously, it has been found that by varying, likewise, the penetration of the medium for the injection of air pressure in the reservoir achieves even greater efficiency in hat breakage and maximizes.
    [0053]
    [0054] Regarding the height or level of the means for the injection to air pressure and penetration of the same inside the tank, according to the procedure and equipment for injection at air pressure, has been determined by a theoretical study of the system of forces generated by the action of the diffusers of pumping that the maximum plastic deformation that produces the efficient breaking of the hat and maximizes the extraction of polyphenolic and aromatic compounds, is obtained with the arrangement of the diffusers according to the dimensions indicated in the following table:
    [0055]
    [0056]
    [0057]
    [0058]
    [0059] Where:
    [0060]
    [0061] "D" is the diameter of the circular deposit or the longest diagonal, in case the deposit is polygonal,
    [0062] "N" is the number of diffusers installed in the tank.
    [0063] "h" is the height of the diffuser in mm and,
    [0064] "p" the penetration of the diffuser in the tank, in mm.
    [0065]
    [0066] Results that have also been experimentally verified during the realization of the investigations that have given rise to the invention.
    [0067]
    [0068] Regarding the performance of the system of pumping over each of these phases and the result of the research carried out, it has been discovered that in the pre- and post-fermentation stages, the overhaul can be limited to the homogenization of the entire mass in winemaking, extending the contact time between the solid and liquid phases, so these pumping over have a shorter and less frequent injection of air. However, during the two stages of alcoholic fermentation (FAL1 and FAL2), when the carbon generation is higher and the hat is more compact, longer and more frequent injections are advantageous. These more intense and frequent injections allow, in addition, a greater release of carbon dioxide from the mass in winemaking, with the desired effect of the containment or reduction of the temperature of the medium that counteracts the increase in temperature that this mass suffers from the process itself fermentative
    [0069] From all of the above, it follows that the times of operation of the pumping system according to the invention in each of the phases are the following:
    [0070]
    [0071]
    [0072]
    [0073]
    [0074] where:
    [0075]
    [0076] injection time (ti), is the time during which each pair of injectors enters gas in the tank uninterruptedly
    [0077]
    [0078] switching time (t c ), is the time that elapses between the injection of a pair of diffusers and the injection of the pair of consecutive diffusers
    [0079] cycle rest time (t r ), is the time that elapses between the completion of a pumping cycles and the beginning of the next cycle, a cycle consisting in the performance of all pairs of diffusers sequentially.
    [0080]
    [0081] Where n is the number of diffuser pairs, the total injection time per cycle is nt i , the total switching time per cycle is (n-1) t c , and the total rest time per cycle is t r .
    [0082]
    [0083] As regards the number of daily pumping over depending on the grape variety and its phenolic maturity for the different stages in which the performance of the pumping system has been divided, the following intervals have been determined:
    [0084]
    [0085]
    [0086]
    [0087]
    [0088] Varieties with a high content of polyphenolic compounds (these compounds are present both in the skin and in the pulp of the fruit) are, for. Example, the Garnacha Tintorera.
    [0089]
    [0090] Varieties with a medium content of polyphenolic compounds (these compounds are present in the skin of the fruit), are, for. Example: Tempranillo, Monastrell, Syrah, Carbernet Sauvignon, etc
    [0091]
    [0092] And, the varieties with low content of polyphenolic compounds (these compounds are present in the skin of the fruit in very low concentration), we can mention, as an example, the pinot noir
    [0093]
    [0094] Regarding the degree of maturation or phenolic maturity index (MFI) or value from which the grape is very close to reaching the maximum value of probable color, and where the astringency and the greenness of the tannins of the skin approach the minimum value, can be measured with the system or equipment CROMOENOS. Establishing that for MFI <1.5 the grape reaches its optimum state of phenolic maturity and, for MFI> 1.5, the grape is not phenolically ripe.
    [0095]
    [0096] The operation of the pumping system is as follows: each pair of diffusers is put into operation during the injection time according to the stage of maceration in which we are. During this time, the selected diffuser pair is injecting air into the maceration tank. After the injection time, both diffusers stop. At the end of the commutation time, the next pair of diffusers is started in the sequence, preferably hourly, which will be injecting air into the maceration tank during said injection time. Once all the pairs of diffusers have intervened in the process, they remain in standby during the time of rest, after which, the first pair of diffusers returns to operate during the injection time, after this time, it stops and After the switching time, the second pair of diffusers comes into operation and so on.
    [0097]
    [0098] This operation is repeated with the appropriate times for each stage of the maceration, changing the values and adapting them to each stage of the maceration of the vintage.
    [0099]
    [0100] Advantageously, the actuation times of the pumping system (injection time, switching time and cycle time) can be controlled by a PC, PLC or similar microprocessor, in which the values of the times are fixed or can be set. be varied by the user of the remounting system.
    [0101]
    [0102] An additional feature of the method and the equipment according to the invention is that they achieve the pumping effect on most of the surface of the hat and even on the whole of said surface. For this, the means for the injection of air pressure will be located so that the penetration of said media into the tank will vary conditioned to the area of action of the different media overlapping as little as possible and / or the gas outputs of the media will be arranged asymmetrically in relation to the axes of the deposit section.
    [0103]
    [0104] Another additional feature of the invention is to separate the control valves from the compressed air distribution circuit in order to isolate them from the environment and protect them against dirt, deterioration due to knocks, etc., by installing said valves grouped in a central control valve with the proper protection. In a preferred embodiment said control valves are solenoid valves located in a register cabinet from which the control lines acting on the mechanical valves that allow the passage of air are derived and which, in a preferred embodiment, are inclined seat valves .
    [0105]
    [0106] Likewise, another additional feature of the method and the equipment according to the invention is the inclusion of a cleaning system for the interior of the means for the injection of air pressure which, once the tank has been emptied, remains filled with liquid and / or paste of grapes crushed in its interior that, in certain conditions, can degrade quickly giving rise to putrefactions and undesired substances. To this end, the process is complemented by an injection of water inside the means for the injection of air pressure that drags the residues of the wine inside the said means, cleaning said interior. Next, compressed air is again injected, which dries the means for injection at air pressure, 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.
    [0107]
    [0108] And yet another additional feature of the system according to the invention, is the assembly of the valves for opening and closing the means for injection at air pressure so that, in the event of any problem or breakdown, said valves allow the injection according to a method in that each of them can be put out of service independently, allowing the operation of the rest of the means for the injection of air pressure without paralyzing the system. For this purpose, in a preferred embodiment, in the equipment according to the invention, the opening and closing valves are located between clamp connections, formed by gasket, connection bushing and clamp, installed between fluid cutting elements, such as a valve. ball.
    [0109]
    [0110] Advantageously, the actuation of the pumping 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 seat valve allowing the passage of air.
    [0111]
    [0112] The compressed air used in the pumping system must be free of impurities such as moisture, oils and particles in suspension, so it can purified air (for food use) can be used directly or the process according to the invention can include an air purification step.
    [0113]
    [0114] 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.
    [0115]
    [0116] 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.
