DESCRIPCIONDESCRIPTION
Lfnea de prensado continuo.Continuous pressing line.
Campo tecnicoTechnical field
La presente invencion se refiere al prensado de uva y, en particular, al prensado de uva de mayor o menor alta calidad para obtener vinos de calidad.The present invention relates to grape pressing and, in particular, to pressing grapes of higher or lower quality to obtain quality wines.
Antecedentes de la tecnicaBackground of the technique
En el proceso de produccion del vino, el prensado de la uva es una de las actividades mas diffciles y delicadas.In the wine production process, the pressing of the grape is one of the most difficult and delicate activities.
Para ser exactos, durante el prensado se produce la rotura del hollejo de la uva, lo que libera el contenido de la uva en forma de mosto.To be exact, during pressing, the grape skins are broken, which releases the grape content in the form of must.
Durante esta operacion, en el caso de las uvas de alta calidad, se debe prestar un cuidado especial en evitar una mala manipulacion mecanica del producto, que podrfa dar lugar a posos no deseados a consecuencia de la destruccion parcial de los hollejos, o incluso de la rotura de las pepitas y de los raspones, lo que liberarfa sustancias no deseadas.During this operation, in the case of high quality grapes, special care should be taken to avoid mechanical mishandling of the product, which could lead to unwanted grounds as a result of the partial destruction of the skins, or even of the breakage of nuggets and scrapes, which would release unwanted substances.
La tecnica anterior proporciona varios tipos de prensas para obtener mosto de vino.The prior art provides several types of presses to obtain wine must.
Se conocen prensas mecanicas, la mas comun de las cuales comprende un tornillo sin fin que funciona dentro de un cilindro perforado, adaptado para empujar mecanicamente la masa de uvas hacia un extremo del cilindro, prensandola continuamente.Mechanical presses are known, the most common of which comprises an endless screw that operates within a perforated cylinder, adapted to mechanically push the mass of grapes towards one end of the cylinder, continuously pressing it.
El prensado mecanico no asegura un prensado suficientemente delicado para garantizar la calidad del mosto, porque las uvas se someten a una mala manipulacion no deseada, a consecuencia del contacto con las partes mecanicas moviles.The mechanical pressing does not ensure a sufficiently delicate pressing to guarantee the quality of the must, because the grapes are subjected to a bad unwanted manipulation, as a result of the contact with the moving mechanical parts.
Estas prensas funcionan de forma continuada y tienen una buena capacidad de produccion, pero ponen de manifiesto una escasa capacidad para adaptar los parametros de prensado —especialmente la presion del prensado— a las condiciones variables del producto que se va a procesar.These presses work continuously and have a good production capacity, but show a low capacity to adapt the pressing parameters - especially the pressing pressure - to the variable conditions of the product to be processed.
Tambien se conocen las denominadas prensas de membrana, donde el prensado de la uva se realiza mediante una membrana deformable que divide un contenedor en dos partes, una de las cuales esta ocupada por el fluido que se presiona, destinado a deformar la membrana, y la otra, provista de una pared perforada, esta ocupada por el producto que se va a prensar.Also known are the so-called membrane presses, where the pressing of the grape is carried out by means of a deformable membrane that divides a container into two parts, one of which is occupied by the fluid that is pressed, destined to deform the membrane, and the another, provided with a perforated wall, is occupied by the product to be pressed.
Las prensas de membrana presentan caracterfsticas que garantizan la delicadeza de prensado deseada, pero tienen la desventaja considerable de funcionar solo en modo discontinuo.Membrane presses have characteristics that guarantee the desired pressing delicacy, but have the considerable disadvantage of operating only in discontinuous mode.
Los tipos de prensa mecanica no son adecuados para el procesamiento de uvas enteras con los raspones, y requieren —antes de su intervencion— que las uvas se prensen y, posiblemente, que se quiten los raspones a fin de evitar que se extraigan sustancias del raspon que comprometan la calidad del mosto.The types of mechanical press are not suitable for the processing of whole grapes with the scratches, and require - before their intervention - that the grapes are pressed and, possibly, that the scrapes be removed in order to avoid removing substances from the scrape that compromise the quality of the must.
La patente US n° 4 421 022 describe una prensa para extraer lfquido de una masa de material fibroso de acuerdo con el preambulo de la reivindicacion 1.US Patent No. 4 421 022 describes a press for extracting liquid from a mass of fibrous material according to the preamble of claim 1.
La prensa comprende un cilindro en el que se desliza un piston accionado por unos medios hidraulicos. El piston esta controlado por un sistema de control. El cilindro esta provisto tambien de una pared final movil conectada a un accionador hidraulico. La pared final esta configurada como un piston que puede pasar entre una posicion cerrada en la que cierra la parte inferior del cilindro y una posicion abierta separada de la boca del cilindro para permitir la descarga del material prensado. La superficie del cilindro presenta una pluralidad de orificios en su parte inferior por los que fluye el lfquido que se separa durante el prensado hacia un colector situado debajo.The press comprises a cylinder in which a piston driven by hydraulic means slides. The piston is controlled by a control system. The cylinder is also provided with a mobile end wall connected to a hydraulic actuator. The final wall is configured as a piston that can pass between a closed position in which the lower part of the cylinder closes and an open position separated from the mouth of the cylinder to allow the discharge of the pressed material. The surface of the cylinder has a plurality of holes in its lower part through which the liquid that separates during pressing flows to a collector located below.
Se conoce otra prensa que esta equipada con un sistema de control para una bomba de piston que permite el ajuste manual del caudal de la bomba mediante un mando.Another press is known that is equipped with a control system for a piston pump that allows manual adjustment of the pump flow rate by means of a control.
La patente US n° 4 279 197 divulga una prensa de tornillo para extraer lfquidos de frutas y productos similares. La prensa esta provista de una jaula en la que funciona el tornillo sobre el material introducido desde una abertura superior. La parte inferior de la jaula esta perforada y la jaula comprende mitades de jaula que pueden pivotar alrededor de un eje pivote cuando se abren, por ejemplo, para las operaciones de limpieza.US Patent No. 4 279 197 discloses a screw press for extracting liquids from fruits and similar products.

de forma ajustada y hermetica en el contenedor cilfndrico 1, asf como una parte conica 92 cuyo vertice esta enfrentado a la pared inferior 11 del contenedor.tightly and tightly in the cylindrical container 1, as well as a conical part 92 whose vertex is facing the bottom wall 11 of the container.
La parte conica tiene la tarea de mejorar la forma de la abertura de descarga para el producto prensado, y tambien puede presentar una forma distinta para adecuarse a la finalidad.The conic part has the task of improving the shape of the discharge opening for the pressed product, and can also present a different form to suit the purpose.
Cuatro aletas de guiado radiales 93 cuyo borde paralelo al eje esta alineado con la parte cilfndrica 90 y cuya parte delantera presenta un borde afilado surgen de la parte conica. Las aletas tienen la finalidad de cortar y partir el material prensado.Four radial guide fins 93 whose edge parallel to the axis is aligned with the cylindrical part 90 and whose front part has a sharp edge arise from the conical part. The fins are intended to cut and split the pressed material.
El recorrido del piston 9 dentro del contenedor se extiende sin ir mas alla de la parte cilfndrica 120 de este.The path of the piston 9 inside the container extends without going beyond the cylindrical part 120 thereof.
Cuando el piston 9 esta dispuesto enfrentado al extremo del contenedor aguas abajo en la direccion del caudal, con la parte cilfndrica cerca de este, pero fuera en relacion con este, se crea una abertura ajustable desde la que se descarga el producto prensado. La posicion del piston esta controlada por el sistema de control central.When the piston 9 is arranged facing the end of the container downstream in the direction of the flow, with the cylindrical part near it, but outside in relation to this, an adjustable opening is created from which the pressed product is discharged. The position of the piston is controlled by the central control system.
En esta posicion, el piston puede estar sujeto a un movimiento de vaiven, de un recorrido breve, para mejorar la operacion de corte y rotura de las aletas. Debajo de la pieza transversal 62 y del accionador 8 esta dispuesta una tina 50 para recoger el producto prensado que sale de la abertura ajustable, que se conoce como la raspa.In this position, the piston can be subject to a movement of vaiven, of a brief route, to improve the operation of cutting and breaking of the fins. Under the transverse piece 62 and the actuator 8, a tub 50 is arranged to collect the pressed product leaving the adjustable opening, which is known as the scraper.
La pared lateral perforada 2 del contenedor 1 comprende una parte superior semicilfndrica 21 (figuras 4, 5), cuyos bordes sostienen una parte 22 conectada mediante una articulacion a estos con una seccion curvada como un cuarto de una superficie cilfndrica, estando cada parte asociada a unos medios (no representados) que la colocan en una posicion cerrada en continuacion con la otra parte y la parte superior, o en una posicion abierta sustancialmente vertical (figura 5).The perforated side wall 2 of the container 1 comprises a semi-cylindrical upper part 21 (figures 4, 5), the edges of which support a part 22 connected by an articulation to these with a curved section like a quarter of a cylindrical surface, each part being associated with means (not shown) that place it in a closed position in continuation with the other part and the upper part, or in a substantially vertical open position (figure 5).
Un sistema de control central, conocido per se, regula la capacidad de la bomba y la posicion del piston en funcion de los diversos parametros monitorizados que estan representados por la presion con la que la bomba suministra al cilindro, por el volumen de la capacidad de la bomba, por el empuje ejercido por el material que se esta descargando en la cabeza del piston y por la posicion del piston.A central control system, known per se, regulates the capacity of the pump and the position of the piston according to the various monitored parameters that are represented by the pressure with which the pump supplies the cylinder, by the volume of the capacity of the pump, for the thrust exerted by the material that is being discharged into the piston head and by the position of the piston.
La invencion funciona del siguiente modo.The invention works as follows.
Al comienzo del prensado el piston 9 se introduce en el contenedor hasta el extremo aguas arriba de la parte cilfndrica 120 de este, y las partes 22 estan en posicion cerrada.At the beginning of pressing the piston 9 is introduced into the container to the upstream end of the cylindrical part 120 thereof, and the parts 22 are in the closed position.
Una bomba, no representada, del tipo que opera a un regimen bajo y a una velocidad controlada por el sistema de control central, envfa el producto al contenedor 1 a traves de la conexion 12 situada en la pared inferior 11 de este.A pump, not shown, of the type that operates at a low rate and at a speed controlled by the central control system, sends the product to the container 1 through the connection 12 located in the lower wall 11 thereof.
La conexion puede estar convenientemente provista de una valvula unidireccional (no representada) adaptada para prevenir el retroceso del producto hacia la bomba. El producto puede estar constituido por uvas enteras o despalilladas y tambien comprende una fase lfquida constituida por jugo.The connection can be conveniently provided with a unidirectional valve (not shown) adapted to prevent the return of the product to the pump. The product may consist of whole or destemmed grapes and also comprises a liquid phase consisting of juice.
Una vez que la fase solida del producto llena la parte del contenedor cilfndrico limitada por el piston 9, mientras la fase lfquida presente se drena a traves de la pared perforada del contenedor, al seguir bombeando se produce un aumento gradual de la presion hasta que se alcanza el valor de prensado deseado.Once the solid phase of the product fills the part of the cylindrical container limited by the piston 9, while the liquid phase present is drained through the perforated wall of the container, when continuing to pump there is a gradual increase in pressure until it is reaches the desired pressing value.
Al alcanzar este valor, lefdo por el sensor, el sistema de control central controla el piston para que retroceda y aumente el volumen disponible dentro del contenedor, hasta que queda dispuesto inmediatamente fuera del contenedor para crear la abertura para la descarga del material prensado.Upon reaching this value, read by the sensor, the central control system controls the piston so that it retracts and increases the volume available within the container, until it is immediately disposed outside the container to create the opening for the discharge of the pressed material.
La posicion del piston esta calibrada por el sistema de control central de tal manera que mantiene constante el valor deseado de la presion interna.The position of the piston is calibrated by the central control system in such a way that it maintains constant the desired value of the internal pressure.
Al continuar el bombeo, el material prensado sale de la abertura calibrada en el extremo del contenedor y el prensado y el avance del material se producen de forma continua, a la presion deseada, sin acciones mecanicas y solo debido al suministro presurizado del material. Durante este paso, el jugo o el mosto se drena a traves de la pared perforada y cae en la tina 5 situada por debajo, y el material prensado sale de la abertura creada por el piston y cae en la tina 50 situada debajo.When the pumping continues, the pressed material leaves the calibrated opening at the end of the container and the pressing and the advance of the material occur continuously, at the desired pressure, without mechanical actions and only due to the pressurized supply of the material. During this step, the juice or must is drained through the perforated wall and falls into the tub 5 below, and the pressed material leaves the opening created by the piston and falls into the tub 50 below.
La tina 5 puede comprender varias secciones separadas en la direccion de avance del material.The tub 5 may comprise several separate sections in the direction of advance of the material.
En la masa de material prensado el volumen de lfquido se reduce constantemente hacia el extremo aguas abajo del contenedor.In the mass of pressed material the volume of liquid is constantly reduced towards the downstream end of the container.
Tambien la calidad del mosto disminuye a medida que el contenido del mosto disminuye en el material dado que elAlso the quality of the wort decreases as the wort content decreases in the material since the

mejor mosto es el que se prensa en la seccion situada mas aguas abajo del contenedor.The best must is the one that is pressed in the section located further downstream of the container.
Por tanto, es conveniente recibir el mosto selectivamente, mantener la calidad del mosto degradado baja hacia la salida del contenedor.Therefore, it is convenient to receive the must selectively, to keep the quality of the degraded must low towards the exit of the container.
El tamano de la abertura de descarga calibrada esta determinado por la posicion del piston, que esta a su vez determinado por el sistema de control central.The size of the calibrated discharge opening is determined by the position of the piston, which in turn is determined by the central control system.
Al final del prensado la prensa se limpia de la siguiente manera.At the end of pressing the press is cleaned as follows.
La tina 5 llena de mosto se retira y se reemplaza con una tina vacfa.Tub 5 full of must is removed and replaced with an empty tub.
Entonces las partes 22 de la pared perforada, por las que la parte solida del producto cae en la tina situada debajo, se disponen en posicion abierta.Then the parts 22 of the perforated wall, whereby the solid part of the product falls into the tub located below, are arranged in an open position.
Con el fin de facilitar el vaciado completo del contenedor, se hace avanzar el piston hacia su interior hasta el final de la parte cilfndrica de este.In order to facilitate the complete emptying of the container, the piston is advanced inwards to the end of the cylindrical part thereof.
El lavado final puede completar la operacion.The final wash can complete the operation.
Se entiende que la invencion no se limita al ejemplo descrito anteriormente y puede someterse a variaciones y mejoras sin apartarse del alcance de proteccion de las siguientes reivindicaciones.It is understood that the invention is not limited to the example described above and may be subject to variations and improvements without departing from the scope of protection of the following claims.
En realidad, la invencion es adecuada para producir jugo de frutas y verduras distintas de las uvas y los medios para descargar el jugo o el material utilizado pueden ser mecanizados.In fact, the invention is suitable for producing fruit and vegetable juice other than grapes and the means for unloading the juice or the material used can be mechanized.
