    DESCRIPTION
    Refrigerated diaphragm for fermentation tank Technical sector
    The present invention belongs to the industry sector dedicated to the manufacture of devices intended for the processes of treatment and fermentation of alcoholic beverages, especially wine.
    The object of the present invention is to develop a carbon gas accumulation diaphragm, with cooling means, adaptable inside the tanks, to improve the efficiency in temperature controls during the fermentation process.
    Background of the invention
    At present, as is well known, during the wine fermentation process, a separation between the solid part and the liquid part of the grapes takes place inside the tanks, the solid part being floating, and occupying approximately one third part of the total volume.
    When the fermentation process begins to occur, carbonic gas, CO2, is generated, which tends to rise towards the top of the tank, so that the solid mass that remains in flotation is compacted by the effects found of the ascending gas and the force of gravity
    In order to retain the carbonic gas in the ES2181035 patent, the tanks incorporate an inner diaphragm for said purpose, being positioned between the bottom bottom and the top roof, to achieve the retention of a certain amount of CO2 in the chamber that is formed between said diaphragm and the tank, to be able to take advantage of this accumulated energy later, releasing it inside the tank during the fermentation process with the disadvantage that when lacking a cooling system, during the fermentation there is an increase in the temperature that must be controlled and stabilized in previously defined margins so as not to alter the organoleptic properties of the product and thereby achieve the best quality in the final product.
    Currently, the tanks intended for this purpose have temperature control systems of various types, such as an outer jacket, consisting of a cold water circulation system through ducts designed for this purpose.
    There are several different embodiments, but in all cases the water must pass through the ducts that make up the jacket and are arranged outside the fermentation tank, with the disadvantage that a lot of cooling power is lost outside, by contact with the environment, reaching only a small percentage inside the deposits, so its efficiency is very low.
    In addition, cooling only reaches the outside of the tanks, leaving the central part that may be hotter, at the expense of thermal exchange by thermal transmission between the different layers of liquid.
    In order to solve this problem, the outer part of the jacket that is in contact with the environment can be thermally insulated so that all the cooling power passes inside the tank. This partly solves the problem, but has a high economic cost and still does not solve the problem when the deposits are of a considerable diameter.
    Another cooling system is applied when the tanks are of considerable diameters and consists of a series of tubes that are placed inside the tank, connected in series and arranged in a spiral, circulating the cold water inside.
    This cooling system is more efficient than the outer jacket, since being the tubes placed internally, all the cooling power is transmitted directly to the inside of the tank, which considerably improves its performance.
    However, this system is designed to be placed by attaching to the walls of the tank by its internal face and at a distance of about 150-300 mm., Relative to the wall inwards, which also makes the efficiency in the central part of the deposit is significantly reduced.
    There are also other methods used, such as cooling plates, or even cooling the liquid by taking it out of the tank and passing it through an exchanger, but ultimately, pursuing the same purpose,

    control the temperature increase, so that the vinification processes are as stable and homogeneous as possible.
    Description of the invention
    In order to reduce as much as possible the aforementioned inconveniences during the fermentation process, a refrigerated diaphragm has been devised for the fermentation tank, which, adapted inside, is positioned between the bottom and the top of it, retaining carbon dioxide produced during fermentation.
    The refrigerated diaphragm comprises a funnel structure, open both at its top and bottom, and perimetrically closed, incorporating a cooling device for the circulation of cooling fluid to homogenize the temperature control.
    The refrigeration device coupled to the refrigerated diaphragm, provides high performance in temperature control because of its design and location makes energy use during the fermentation process optimal.
    The cooling device that incorporates the refrigerated diaphragm comprises circulation channels, coupled in solidarity with the outer perimeter of said refrigerated diaphragm, incorporating inlet and outlet connections of the cooling liquid.
    In an alternative embodiment, the cooled diaphragm comprises a cooling device, based on a coil, which incorporates connections for the inlet and outlet of the cooling liquid, coupled to the bottom of the cooled diaphragm through tie-down plates.
    In another alternative embodiment, the cooled diaphragm comprises a cooling device, based on at least two cooling plates, incorporating connections for the entry and exit of the cooling liquid, communicated with the upper and lower part of the cooled diaphragm, and attached to its structure through tie plates.
    Functioning
    With the upper lid of the tank open and the CO2 release valve closed, the tank is filled.
    That way, the level will rise throughout the reservoir until it reaches the bottom of the refrigerated diaphragm.
    From that moment, as the CO2 release valve is closed, and the refrigerated diaphragm is hermetic and is jointly attached to the inner walls of the aforementioned tank, the air that occupies the volume that forms between the outer walls of the refrigerated diaphragm and the inner walls of the tank is trapped, forming a chamber, and consequently, said chamber cannot be flooded since in order for this to be achieved, a pressure in the liquid or in the reservoir, greater than a bar, should be exerted .
    Then, the liquid level will continue to rise through the cooled diaphragm until it reaches its maximum level of filling in the tank, leaving the chamber full of air.
    At the beginning of the fermentation, and keeping the CO2 release valve closed, spontaneously during the aforementioned fermentation process, part of the CO2 generated will accumulate in the chamber that until now was full of air.
    At a certain time, and under the control of an automatic control panel, to control the fermentation temperature, the cooling device that incorporates the refrigerated diaphragm, which acts directly in a critical area, of higher temperature accumulation, will be put into operation.
    Due to an incessant increase of CO2 pressure in the chamber, there is a bubbling that rises to the top of the tank, crossing the refrigerated diaphragm and moving liquid that is cooled in that area, towards the bottom of the solid mass that has maximum temperature accumulation, thus achieving homogenization in the cooling process.
    When the chamber is full of CO2, the CO2 release valve is opened, evacuating the CO2 through it, and allowing the liquid level to rise in the chamber, leaving the chamber completely flooded, getting in this way that the solid part is mixed with the liquid part, so that, when the diaphragm cooling device is in operation, an optimal homogenization in temperature control is achieved, homogenization which, with traditional systems is absolutely impossible.

    From that moment, the release valve is closed again, so that the CO2 that is generated during the fermentation will accumulate again in the chamber, so that the CO2 will exert pressure on the liquid which, since it cannot be compressed, will progressively move downwards until the CO2 occupies the total capacity of the accumulation chamber.
    At that moment, the excess of CO2 will bubble into the upper part of the tank, returning to the initial conditions and during the fermentation period, the described process will be repeated cyclically with the opening / closing of the release valve.
    The person skilled in the art will readily understand that he can combine characteristics of different embodiments with characteristics of other possible embodiments, provided that such combination is technically possible.
    Advantages of the invention
    The refrigerated diaphragm for the fermentation tank that is presented, provides multiple advantages over the systems currently available to homogenize the fermentation, the most important being to integrate into the interior of a tank, incorporating a cooling device on the outer perimeter of the said diaphragm , providing high performance in temperature control, since its design and location makes energy use during the fermentation process optimal.
    Another advantage is that the chilled diaphragm, in an alternative embodiment incorporates a coil coupled to the bottom of the chilled diaphragm through mooring plates.
    As an advantage, it should be added that in another alternative embodiment, the refrigerated diaphragm incorporates at least two cooling plates, communicated with the upper part of the diaphragm and attached to its structure through tie-down plates.
