DESCRIPCIÓN  DESCRIPTION
Afofador para banda de difusión Campo técnico de la invención Afofador for diffusion band Technical field of the invention
La presente invención corresponde al campo técnico de las bandas de difusión utilizadas en difusores para extraer los azucares de diferentes materias primas a través del lavado continuo de la materia prima troceada y depositada sobre la banda de difusión y en concreto al afofador de la materia prima situado sobre dicha banda de difusión para esponjar el lecho de materia prima situado en la misma. The present invention corresponds to the technical field of diffusion bands used in diffusers to extract the sugars of different raw materials through the continuous washing of the raw material chopped and deposited on the diffusion band and in particular to the afofador of the situated raw material on said diffusion band to sponge the bed of raw material located therein.
Antecedentes de la Invención Background of the Invention
El afofador es un elemento interno de la banda de difusión que se utiliza en los difusores para la extracción de los azúcares de distintas materias primas mediante el lavado de la misma. El afofador se utiliza para mullir o afofar de manera homogénea del lecho de materia prima que avanza sobre la banda de difusión. The afofador is an internal element of the diffusion band that is used in the diffusers for the extraction of sugars of different raw materials by washing it. The chiller is used to smoothly or loosely homogenize the bed of raw material that advances on the diffusion band.
Los afofadores son necesarios debido a que, durante el trayecto de avance del lecho de materia prima sobre el conjunto de paletas de la banda de difusión, dicho lecho va recibiendo los repetidos impactos de las descargas de jugo que proporcionan los volteos de los balanceles. Estos repetidos impactos de jugo, hacen que el lecho de materia prima se vaya compactando y en consecuencia, que se vaya haciendo impermeable y dificulte el paso del jugo a través del lecho y del conjunto de paletas. Este mismo efecto de compactacion de la materia prima se produce en difusores que utilizan un lavado continuo de la materia prima. The afofadores are necessary because, during the course of advance of the bed of raw material on the set of palettes of the band of diffusion, said bed is receiving the repeated impacts of the jumps of juice that provide the flips of the balances. These repeated impacts of juice, make the bed of raw material is compacted and consequently, that it becomes impermeable and makes it difficult to pass the juice through the bed and the set of pallets. This same effect of compaction of the raw material occurs in diffusers that use a continuous washing of the raw material.
Cuando esto ocurre, se forman encharcamientos o caminos preferenciales del líquido, que no son beneficiosos para el correcto funcionamiento del difusor. Por este motivo, cada cierto espacio dependiendo del tipo de materia prima, se instalan afofadores. When this occurs, pools or preferential paths of the liquid are formed, which are not beneficial for the proper functioning of the diffuser. For this reason, every certain space depending on the type of raw material, afofadores are installed.
El afofador es un elemento formado por un eje con aletas que va volteando la materia prima a medida que le va llegando con el avance de la banda de difusión. Los afofadores no avanzan con el conjunto de paletas, sino que están fijados a las paredes del difusor. El movimiento de volteo del material se consigue mediante un motorreductor que cada afofador lleva asociado. En la actualidad, se disponen varios afofadores a lo largo de una banda de difusión, tantos como requiera el tipo de materia prima que se está procesando, pues existen materias más propensas a compactarse que precisan más cantidad de afofadores que las materias con menos capacidad de compactación. Estos afofadores se encuentran situados tan solo unos centímetros por encima de las paletas o conjunto de paletas que conforman la banda de difusión situando el eje del afofador en posición transversal al movimiento de las paletas y paralelo a las mismas, de manera que puedan afofar la mayor parte del lecho de materia prima, sin llegar a interferir con dichas paletas. The afofador is an element formed by a shaft with fins that turns the raw material as it arrives with the advance of the diffusion band. The afofadores do not advance with the set of vanes, but they are fixed to the walls of the diffuser. The flipping movement of the material is achieved by means of a gearmotor that each afofador has associated. At present, several afofadores are arranged along a diffusion band, as many as the type of raw material that is being processed requires, since there are more prone materials to be compacted that require more quantity of afofadores than materials with less capacity to compaction These chokes are located just a few centimeters above the vanes or set of blades that make up the diffusion band by placing the shaft of the choker in a transverse position to the movement of the blades and parallel to them, so that they can focus part of the raw material bed, without interfering with said pallets.
Los afofadores utilizados en el estado de la técnica se instalan formando hileras de afofadores de la banda de difusión y se disponen de forma vertical (perpendicular a las paletas o lecho de materia prima) en cada punto de la banda de difusión que se decide afofar. The afofadores used in the state of the art are installed forming rows of afofadores of the diffusion band and are arranged vertically (perpendicular to the pallets or bed of raw material) at each point of the diffusion band that is decided to afofar.
Estos afofadores presentan una serie de inconvenientes, como es el hecho de que al ser afofadores verticales dispuestos en línea, actúan sobre puntos concretos de la banda de difusión y sólo consiguen afofar la zona que pasa cercana a cada afofador, pero no se consigue afofar de igual modo la zona que queda entre un afofador vertical y el contiguo. Debido a esto, la superficie se queda de manera irregular, por lo que pueden formarse caminos preferenciales del jugo de recirculación que recibe el lecho de materia prima. Además, el sistema de afofadores verticales necesita un motorreductor por cada uno de los afofadores, y el número de éstos depende de la mayor o menor anchura de la banda de difusión, con lo que la inversión económica puede llegar a ser bastante elevada. These chokers have a series of drawbacks, such as the fact that being vertical chokers arranged in line, they act on specific points of the diffusion band and only manage to block the area that passes close to each choker, but it is not possible to flush out Similarly, the area between a vertical and adjacent grocer. Due to this, the surface remains irregularly, so that preferential paths of the recirculation juice that receives the bed of raw material can be formed. In addition, the vertical choking system requires a gearmotor for each of the chokes, and the number of these depends on the greater or lesser width of the diffusion band, so that the economic investment can become quite high.

El afofador para banda de difusión, utilizada en difusores para extraer los azucares de diferentes materias primas a través del lavado continuo de la materia prima troceada y depositada sobre la banda de difusión, donde el afofador está situado sobre la banda de difusión para esponjar el lecho de materia prima situado en la misma que aquí se presenta, comprende un eje central dispuesto de forma horizontal, transversal al sentido de avance de la materia prima y tal que abarca el ancho total de la banda de difusión, y del que emerge al menos una aleta longitudinal. The spreader for the diffusion band, used in diffusers to extract the sugars of different raw materials through the continuous washing of the raw material chopped and deposited on the diffusion band, where the stiffener is located on the diffusion band to sponge the bed of raw material located therein, it comprises a central axis arranged horizontally, transverse to the direction of advance of the raw material and such that it covers the total width of the diffusion band, and from which at least one longitudinal fin
En al menos un extremo del eje central está conectado mediante unos medios de conexión a un motorreductor que genera el movimiento de rotación de la al menos una aleta sobre la superficie del lecho de materia prima. At least one end of the central axis is connected by means of connection to a geared motor that generates the rotational movement of the at least one fin on the surface of the raw material bed.
Por otra parte, dicha al menos una aleta presenta un ancho tal que el extremo de la misma, en su posición de rotación más baja, está comprendido entre el plano definido por la banda de difusión y el plano superior definido por la materia prima a ser tratada. On the other hand, said at least one fin has a width such that the end thereof, in its lowest rotation position, is comprised between the plane defined by the diffusion band and the upper plane defined by the raw material to be treated.
En una realización preferente, el afofador comprende unos medios de sujeción de los extremos del eje central a las paredes laterales del difusor, formados por unos soportes de rodamiento. Tratándose de ejes largos que pueden flexar, este eje central apoyado en los extremos puede tener soportes intermedios que eviten esa flexión. In a preferred embodiment, the spreader comprises means for fastening the ends of the central axis to the side walls of the diffuser, formed by rolling supports. In the case of long axes that can flex, this central axis supported at the ends can have intermediate supports that avoid this flexion.
De acuerdo con una realización preferente, los medios de conexión de al menos un extremo del eje central al motorreductor está formados por un acoplamiento mecánico. According to a preferred embodiment, the connection means of at least one end of the central axis to the geared motor is formed by a mechanical coupling.
Según una realización preferida, la al menos una aleta está dispuesta de forma radial. According to a preferred embodiment, the at least one fin is radially arranged.
En otra realización preferente, la al menos una aleta está dispuesta de forma helicoidal. Así mismo, en cualquiera de los casos anteriores, de acuerdo con una realización preferida, la al menos una aleta es continua en toda la longitud del eje central, mientras que en otra realización preferente, la al menos una aleta es discontinua. In another preferred embodiment, the at least one fin is helically arranged. Likewise, in any of the above cases, according to a preferred embodiment, the at least one fin is continuous along the entire length of the central axis, while in another preferred embodiment, the at least one fin is discontinuous.
Según una realización preferente, el eje central presenta al menos dos aletas longitudinales dispuestas de forma equidistante entre sí. According to a preferred embodiment, the central axis has at least two longitudinal fins arranged equidistant from each other.
De acuerdo con otro aspecto, el afofador comprende unos medios de bloqueo del funcionamiento de la banda de difusión que impiden el funcionamiento de la misma cuando está parado el motorreductor principal del afofador e igualmente existen una serie de enervamientos entre los diferentes motores de la banda de difusión que evitan que se puedan poner en funcionamiento si otros no lo están o que se paren si otros se han parado. According to another aspect, the chiller includes means for blocking the operation of the diffusion band that prevent its operation when the main gearmotor of the chiller is stopped and there are also a series of enervations between the different motors of the band of dissemination that prevent them from being put into operation if others are not or stop if others have stopped.
Con el afofador para banda de difusión que aquí se propone se obtiene una mejora significativa del estado de la técnica. A significant improvement in the state of the art is obtained with the diffuser band diffuser proposed here.
Esto es así pues gracias a la forma de este afofador, de diseño horizontal que abarca todo el ancho de la banda de difusión, se consigue voltear toda la sección de matena prima que pasa por la banda de difusión al mismo tiempo, con lo que se logra que la superficie superior de dicha matena prima quede homogénea, casi como una superficie plana sin demasiadas irregularidades. Además, gracias al modo de disposición del afofador en horizontal, no es necesaria la instalación de múltiples afofadores, sino que con un único afofador en la etapa del difusor donde se pretende mullir la materia prima, es suficiente, aunque a lo largo del difusor puede haber más de un afofador. Conviene aclarar que habrá un solo afofador en cada área donde se requiere mullir la materia prima, a diferencia de las alternativas tecnológicas que requieren más de un afofado. Esto tiene la ventaja de que resulta un sistema mucho más sencillo, pues únicamente se requiere de la instalación de un único motorreductor, con el consiguiente ahorro de energía. Así pues, a pesar de que este motorreductor debe ser de mayores dimensiones que los utilizados en cada afofador vertical del estado de la técnica, el coste total del sistema afofador y su consumo eléctrico se reduce respecto a los sistemas existentes de afofadores verticales. This is so thanks to the shape of this afofador, of horizontal design that covers the entire width of the diffusion band, it is possible to flip the entire section of raw matena that passes through the diffusion band at the same time, with which it makes the top surface of said raw matena homogeneous, almost like a flat surface without too many irregularities. In addition, thanks to the disposition mode of the horizontal spreader, it is not necessary to install multiple spreaders, but with a single spreader at the stage of the diffuser where the raw material is intended to be milled, it is sufficient, although along the diffuser it can There is more than one choker. It should be clarified that there will be only one locker in each area where the raw material is required to mull, unlike the technological alternatives that require more than one formwork. This has the advantage that it is a much simpler system, since it only requires the installation of a single geared motor, with the consequent energy savings. Thus, despite the fact that this gearmotor must be larger than those used in each vertical chiller of the prior art, the total cost of the chiller system and its electrical consumption is reduced compared to the existing vertical choker systems.
Además, existe un menor número de elementos susceptibles de averiarse, con lo que se reducen los costes por reparación y mantenimiento. In addition, there are fewer items that can be damaged, reducing costs for repair and maintenance.
Resulta pues, un afofador mucho más eficaz, sencillo y práctico. It is therefore a much more efficient, simple and practical afofador.

Con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se aporta como parte integrante de dicha descripción, una serie de dibujos donde, con carácter ilustrativo y no limitativo, se ha representado lo siguiente: In order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, an integral part of said description is provided, a series of drawings where, for illustrative and non-limiting purposes, represented the following:
La Figura 1 .- Muestra una vista en perspectiva del afofador para banda de difusión, para un modo de realización preferente de la invención. Figure 1 .- Shows a perspective view of the spreader for diffusion band, for a preferred embodiment of the invention.
Descripción detallada de un modo de realización preferente de la invención Detailed description of a preferred embodiment of the invention
A la vista de la figura aportada, puede observarse cómo en un modo de realización preferente de la invención, el afofador (1 ) para banda de difusión, utilizada en difusores para extraer los azucares de diferentes materias primas a través del lavado continuo de la materia prima troceada y depositada sobre la banda de difusión que aquí se propone, está situado sobre la banda de difusión para esponjar el lecho de materia prima situado en la misma. In view of the figure provided, it can be seen how in a preferred embodiment of the invention, the spreader (1) for diffusion band, used in diffusers to extract the sugars of different raw materials through the continuous washing of the chopped raw material and deposited on the diffusion band that is proposed here, it is located on the diffusion band to sponge the bed of raw material located in the same.
Este afofador (1 ) comprende un eje central (2) dispuesto de forma horizontal de manera que abarca el ancho total de la banda de difusión, y del que emerge al menos una aleta (3) longitudinal. En este modo de realización preferente de la invención, como se muestra en la Figura 1 , del eje central (2) emerge un total de tres aletas (3) dispuestas de forma radial y de forma equidistantes entre sí. Así mismo, en este modo de realización, estas tres aletas (3) son continuas en toda la longitud del eje central (2). Debe señalarse que el número de aletas dependerá de las características del diseño, pudiéndose hacer soluciones con menos o más aletas según interese. This chiller (1) comprises a central axis (2) arranged horizontally so that it covers the total width of the diffusion band, and from which at least one longitudinal fin (3) emerges. In this preferred embodiment of the invention, as shown in Figure 1, from the central axis (2) a total of three fins (3) arranged radially and equidistant from each other emerge. Likewise, in this embodiment, these three fins (3) are continuous along the entire length of the central axis (2). It should be noted that the number of fins will depend on the characteristics of the design, being able to make solutions with less or more fins according to interest.
Como se muestra en la Figura 1 , un extremo (4.1 ) del eje central (2) está conectado mediante unos medios de conexión a un motorreductor (5). Este motorreductor (5) es el que genera el movimiento de rotación de las tres aletas (3) sobre la superficie del lecho de materia prima. As shown in Figure 1, one end (4.1) of the central shaft (2) is connected by means of connection to a gearmotor (5). This gearmotor (5) is the one that generates the rotation movement of the three fins (3) on the surface of the raw material bed.
Además, las tres aletas (3) del afofador (1 ) presentan un ancho tal que el extremo de las mismas, en su posición de rotación más baja, está comprendido entre el plano definido por la banda de difusión y el plano superior definido por la materia prima a ser tratada. In addition, the three fins (3) of the chiller (1) have a width such that the end thereof, in its lowest rotational position, is comprised between the plane defined by the diffusion band and the upper plane defined by the Raw material to be treated.
En este modo de realización preferente de la invención, el afofador (1 ) comprende unos medios de sujeción de los extremos del eje central (4.1 , 4.2) a las paredes laterales del difusor, formados por unos soportes de rodamiento (6). En caso de ser necesario y tratándose de ejes centrales de gran longitud y para evitar flexiones del mismo, se pueden disponer apoyos centrales o intermedios en dicho eje. Por otra parte, en este modo de realización preferente, los medios de conexión de uno de los extremos (4.1 ) del eje central (2) al motorreductor (5) están formados por un acoplamiento mecánico. En este modo de realización preferente de la invención, el afofador (1 ) comprende unos medios de bloqueo del funcionamiento de la banda de difusión que impiden su funcionamiento cuando está parado el motorreductor (5) del afofador (1 ). In this preferred embodiment of the invention, the spreader (1) comprises means for fastening the ends of the central shaft (4.1, 4.2) to the side walls of the diffuser, formed by rolling supports (6). If necessary and in the case of central axes of great length and to avoid bending thereof, central or intermediate supports can be provided on said axis. On the other hand, in this preferred embodiment, the means for connecting one of the ends (4.1) of the central shaft (2) to the gearmotor (5) are formed by a mechanical coupling. In this preferred embodiment of the invention, the chiller (1) comprises means for blocking the operation of the diffusion band that prevent its operation when the geared motor (5) of the chiller (1) is stopped.
De este modo, gracias a los medios de bloqueo, se evita que la banda de difusión siga funcionando en caso de que el motorreductor (5) del afofador (1 ) se pare, pues esto podría generar daños en alguno de los componentes internos del difusor o incluso en el propio afofador (1 ). In this way, thanks to the blocking means, the diffusion band is prevented from continuing to operate if the gearmotor (5) of the choke (1) stops, as this could cause damage to any of the internal components of the diffuser or even in the chiller itself (1).
La forma de realización descrita constituye únicamente un ejemplo de la presente invención, por tanto, los detalles, términos y frases específicos utilizados en la presente memoria no se han de considerar como limitativos, sino que han de entenderse únicamente como una base para las reivindicaciones y como una base representativa que proporcione una descripción comprensible así como la información suficiente al experto en la materia para aplicar la presente invención. The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
Con el afofador para banda de difusión que aquí se presenta se consiguen importantes mejoras respecto al estado de la técnica. With the spreader for diffusion band presented here, significant improvements are achieved with respect to the state of the art.
Se consigue un afofador en el que gracias a su disposición horizontal que abarca todo el ancho de la banda de difusión, con una única unidad del mismo es posible afofar toda la sección de materia prima que circula por la banda. Con ello se logra una mayor homogeneización de la superficie superior de materia prima y por tanto una menor posibilidad de formación de caminos preferenciales del jugo. Al conseguir afofar toda la sección con un único afofador, se reduce el número de afofadores necesarios y sobretodo, el número de motorreductores utilizados, ya que con un único motorreductor es suficiente. Esto supone una importante reducción de los costes, tanto de inversión, como de mantenimiento. A chiller is achieved in which, thanks to its horizontal arrangement that covers the entire width of the diffusion band, with a single unit of it, it is possible to flush the entire section of raw material that circulates through the band. This results in a greater homogenization of the upper surface of raw material and therefore a lower possibility of forming preferential juice paths. By getting the whole section afofar with a single stiffener, the number of afofadores needed is reduced and above all, the number of gearmotors used, since with a single gearmotor is sufficient. This is an important cost reduction, both investment and maintenance.
