En un primer aspecto, la invención se refiere a un molino desfibrador que comprende una tolva para recibir los productos a desfibrar, un par de discos (primer y segundo) enfrentados y coaxiales, adaptados para realizar el troceado del producto y servir de soporte para el posterior desfibrado, unas cadenas perimetrales encargadas de dicho desfibrado, y un motor adaptado para activar la rotación de los discos. In a first aspect, the invention relates to a defibrator mill comprising a hopper to receive the products to be defibrated, a pair of coaxial (first and second) discs, adapted to perform the product slicing and to support the product. later defibrated, perimeter chains responsible for said defibration, and an engine adapted to activate the rotation of the discs.
Así, el molino desfibrador comprende un primer disco, provisto de al menos una abertura adaptada y una cuchilla alojada en la abertura y colocada para cortar inicialmente los productos recibidos de la tolva. Además, la abertura está dimensionada para permitir el paso de los productos cortados al espacio definido entre ambos discos. De esta forma, el molino permite un primer troceado del producto, donde, la velocidad y tamaño del troceado variarán en función del número de cuchillas y de las dimensiones del espacio de paso definido entre cada abertura y la cuchilla que aloja. Así, a mayor número de cuchillas y a mayor espacio de paso en las aberturas, mayor será la velocidad del troceado inicial. Reduciendo el espacio de paso podrá reducirse las dimensiones del troceado. Thus, the defibrator mill comprises a first disk, provided with at least one adapted opening and a blade housed in the opening and placed to initially cut the products received from the hopper. In addition, the opening is sized to allow the passage of the cut products to the defined space between both discs. In this way, the mill allows a first chopping of the product, where the speed and size of the chopping will vary depending on the number of blades and the dimensions of the defined passage space between each opening and the blade it houses. Thus, the greater the number of blades and the greater the passage space in the openings, the greater the speed of the initial cutting. Reducing the passage space can reduce the dimensions of the slicing.
Estas cuchillas se alojan en las aberturas de forma desmontable permitiendo incluir cuchillas en todas las aberturas o se pueden retirar algunas de ellas, todo ello en función del tamaño del producto a trocear. These blades are housed in the openings in a removable way allowing to include blades in all the openings or some of them can be removed, all depending on the size of the product to be cut.
Estas cuchillas permiten la variación de su separación al disco rotor lo que permitirá definir el tamaño con el que el producto llegará a las cuchillas perimetrales y cadenas. Esta variación se logra mediante la inclusión de láminas suplementarias a colocar entre las cuchillas y el disco rotor y que poseen la misma geometría de las cuchillas. Las cadenas están perimetralmente dispuestas entre los extremos del primer y del segundo disco para permitir el desfibrado del producto cortado. These blades allow the variation of their separation to the rotor disk which will allow to define the size with which the product will reach the perimeter blades and chains. This variation is achieved by the inclusion of additional sheets to be placed between the blades and the rotor disk and which have the same blade geometry. The chains are perimetrically arranged between the ends of the first and second disc to allow defibration of the cut product.
Finalmente, el motor, preferentemente eléctrico, activa la rotación de los discos. Finally, the motor, preferably electric, activates the rotation of the disks.

Realización preferente de la invención Preferred Embodiment of the Invention
La figura 1 muestra una vista parcial del molino desfibrador (1) en la que se aprecia el primer disco (3) provisto de una serie de aberturas (13) radialmente dispuestas, donde dichas aberturas (13) alojan cuchillas (5). Figure 1 shows a partial view of the defibrator mill (1) in which the first disk (3) is provided with a series of radially arranged openings (13), where said openings (13) house blades (5).
Como se observa, las cuchillas (3) preferentemente se extienden a lo largo de una de las direcciones mayores de la abertura (13). Así, si las aberturas (13) son rectangulares, las cuchillas (5) se extienden en uno de sus lados largos. Así mismo, las aberturas (13) están dimensionadas para permitir el paso de los productos cortados al espacio definido entre el primer (3) y el segundo disco (4). As noted, the blades (3) preferably extend along one of the major directions of the opening (13). Thus, if the openings (13) are rectangular, the blades (5) extend on one of their long sides. Likewise, the openings (13) are sized to allow the passage of the cut products to the defined space between the first (3) and the second disk (4).
En la figura 5 se muestra una vista explotada del disco (3) y como se fijan las cuchillas (5) al citado disco mediante atornillado y como en el espacio (17) entre cuchillas y disco se intercalan laminas suplementarias (no dibujadas), que poseen la misma geometría de las cuchillas y que separan a las cuchillas del disco y asi definen el tamaño del producto que llegará a las cuchillas auxiliares (7) y a las cadenas (6). Figure 5 shows an exploded view of the disk (3) and how the blades (5) are fixed to the aforementioned disk by screwing and as in the space (17) between blades and disk additional sheets (not drawn) are inserted, which they have the same geometry of the blades and that separate the blades from the disk and thus define the size of the product that will reach the auxiliary blades (7) and the chains (6).
El molino desfibrador (1), como hemos anticipado, también comprende cadenas (6) ancladas entre ambos discos (3, 4) y encargadas de permitir el desfibrado de la materia prima una vez troceada. The shredder mill (1), as we have anticipated, also includes chains (6) anchored between both discs (3, 4) and responsible for allowing the defibration of the raw material once chopped.
Así mismo, el molino desfibrador (1) de la figura 1 cuenta con cuchillas auxiliares (7) dispuestas perimetralmente entre los bordes del primer (3) y del segundo disco (4) para trocear el producto retenido en el espacio definido entre ambos discos (3, 4). Estas cuchillas auxiliares (7) se disponen perimetralmente al primer (3) y segundo disco (4) pudiendo variar en su número, es decir se pueden poner un mayor o un menor número de ellas, lo que influirá en el troceado del producto. Estas cuchillas auxiliares (3) dispuestas perimetralmente se fijan mediante atornillado a unos perfiles fijos entre ambos discos de tal forma que se pueden quitar o añadir cuchillas para buscar un determinado resultado durante la operación. Likewise, the defibrator mill (1) of Figure 1 has auxiliary blades (7) arranged perimetrically between the edges of the first (3) and the second disc (4) to cut the retained product into the space defined between both discs ( 3. 4). These auxiliary blades (7) are arranged perimetrically to the first (3) and second disc (4) and may vary in number, that is, a greater or lesser number of them can be placed, which will influence the slicing of the product. These auxiliary blades (3) arranged perimetrically are fixed by screwing to fixed profiles between both discs so that blades can be removed or added to look for a certain result during operation.
En la figura 2 se muestra ambos discos (3, 4), enfrentados y montados sobre un mismo eje (10) para rotar con la activación del motor (14). Figure 2 shows both discs (3, 4), facing and mounted on the same axis (10) to rotate with the activation of the motor (14).
Igualmente, la figura 2 muestra las cadenas (6) y las cuchillas auxiliares (7). Tanto las cadenas (6) como las cuchillas auxiliares (7), a la vez que desfibran y trocean el producto, también lanzan o hacen que el producto salga despedido contra la carcasa (9) del molino debido a la fuerza centrífuga que este movimiento de rotación de los discos genera. Similarly, Figure 2 shows the chains (6) and the auxiliary blades (7). Both the chains (6) and the auxiliary blades (7), while they defibrate and chop the product, also throw or cause the product to be fired against the casing (9) of the mill due to the centrifugal force that this movement of Disk rotation generates.
La carcasa (9) evita que el operario entre en contacto con las cuchillas (5), y en caso de desprendimiento de algún elemento interno la carcasa (9), asegura la integra seguridad de todo el personal. The housing (9) prevents the operator from coming into contact with the blades (5), and in case of detachment of some internal element the housing (9), ensures the integral safety of all personnel.
La cara interna de la carcasa (9) aloja una pluralidad de piezas de acero tratado térmicamente que reciben los impactos del producto que sale despedido hacia dicha carcasa. Este conjunto de piezas que reciben los impactos del producto y que ayudan a terminar de desfibrarlo se denominan comúnmente como sufridera. Esta sufridera es un elemento desmontable y permite reemplazar o reparar todas las piezas que la componen. The inner face of the housing (9) houses a plurality of heat-treated steel parts that receive the impacts of the product that is fired towards said housing. This set of pieces that receive the impacts of the product and that help to finish defibrating it are commonly referred to as sufridera. This suffridera is a removable element and allows you to replace or repair all the parts that compose it.
La figura 3 muestra una un sistema de poleas (15) y correas (16) accionadas por el motor (14) para permitir la rotación de los discos (3, 4). Figure 3 shows a pulley system (15) and belts (16) driven by the motor (14) to allow the rotation of the discs (3, 4).
En la figura 4 se muestra un sistema desfibrador que comprende un molino desfibrador (1) y una estructura metálica compuesta por un bastidor (11) provista de patas (12) y amortiguadores para minimizar las vibraciones del molino desfibradorFigure 4 shows a shredder system comprising a shredder mill (1) and a metal structure composed of a frame (11) provided with legs (12) and dampers to minimize vibrations of the shredder mill

Para la llegada de la materia prima a los discos (3, 4), el molino desfibrador (1) cuenta con una tolva (2) de entrada a través de la cual, y por gravedad entran la materia prima, por ejemplo, las piñas, provenientes de unos transportadores. For the arrival of the raw material to the disks (3, 4), the shredder mill (1) has an input hopper (2) through which, and by gravity, the raw material enters, for example, pineapples , from conveyors.
Los materiales preferentemente usados para el sistema desfibrador serán el acero al carbono y el acero inoxidable, concretamente, para la estructura metálica se utilizará perfilería tales como angulares o pletinas, de acero al carbono, al igual que la carcasa (9) exterior protectora de los discos (3,4), y para los discos (3, 4) y las cadenas (6) de desfibrado, acero inoxidable, ya que sufrirán mucho impacto durante la operación y es necesario que no se produzca un desgaste rápido. The materials preferably used for the shredder system will be carbon steel and stainless steel, specifically, for the metal structure profiles such as angular or flat, carbon steel, as well as the outer protective shell (9) of the discs (3,4), and for discs (3, 4) and defibration chains (6), stainless steel, since they will suffer a lot of impact during the operation and it is necessary that rapid wear does not occur.
