El objeto de la invención comprende una máquina que une a la ventaja de no tener que interrumpir el proceso productivo parar llenar el aparato, otras múltiples cualidades respecto de las embutidoras tradicionales de pistón, siendo una de las principales la importantísima disminución del fenómeno llamado "embarre" (laminado y untado de los trozos de grasa por encima de los trozos magros debido a la fricción), por ser la masa en movimiento de mayores dimensiones, lo contrario que las embutidoras de paletas y otros sistemas, en los que hay una gran proporción de la masa en fricción con las paredes, debido a su poco volumen y a su recorrido. Tal como se describe en el cuerpo de la presente memoria descriptiva, la máquina embutidora de productos cárnicos con dosificación continua provista de los perfeccionamientos objeto del presente registro, ha sido concebida para dar una solución a los problemas existentes en las demás embutidoras continuas que existen en el mercado. Concretamente, el diseño de la máquina hace que, mediante un sistema de pistones coaxiales y la extracción del aire de la masa cárnica simultáneamente, se consiga un trato óptimo de la misma, evitando el embarre producido mediante otros sistemas, y para evitar que en la extracción del aire de la masa se produzcan filtraciones de masa cárnica que puede conllevar a lo largo del tiempo a la obturación de los orificios de los pistones y vastago, reduciendo la eficacia del sistema y con el fin de mantener esta ventaja competitiva de la máquina que la hace diferente a las demás, se ha introducido un sistema de autolimpiado del circuito de vacío que garantiza el buen funcionamiento del mismo.The object of the invention comprises a machine that unites the advantage of not having to interrupt the productive process to fill the apparatus, other multiple qualities with respect to traditional piston stuffers, one of the main ones being the very important decrease of the phenomenon called "embarre "(rolled and spread of the fat pieces above the lean pieces due to friction), because it is the mass in motion of larger dimensions, the opposite of the stuffers of pallets and other systems, in which there is a large proportion of the mass in friction with the walls, due to its low volume and its path. As described in the body of the present specification, the stuffing machine of meat products with continuous dosing provided with the improvements object of the present registry, has been conceived to give a solution to the problems existing in the other continuous stuffers that exist in the market. Specifically, the design of the machine means that, by means of a coaxial piston system and the extraction of the air from the meat mass simultaneously, an optimal treatment of the same is achieved, avoiding the grounding produced by other systems, and to prevent the air extraction from the mass leaks occur of meat mass that can lead over time to the sealing of the holes of the pistons and rod, reducing the efficiency of the system and in order to maintain this competitive advantage of the machine that makes it different from the others, it has introduced a self-cleaning system of the vacuum circuit that guarantees its proper functioning.
Este sistema consiste en la disposición de una entrada de aire a presión conectada al extremo anterior del conducto tubular central que discurre axialmente, y a través de un tapón de acceso, de manera que, cuando los pistones llegan al final de carrera, el contacto acciona una electroválvula ocasionando la salida del aire a presión que permanece hasta que el distribuidor realiza el movimiento de giro. En el diseño general del núcleo interior, se han practicado unos orificios que permiten que el aire a presión circule a través de ellos para expulsar la masa cárnica existente y arrastrarla a través del conducto tubular central hasta la cámara de vacío en el extremo posterior de la máquina. Esta operación se realiza en el pistón del cilindro que está completamente vacío ya que en esta situación el núcleo interior se encuentra en una posición tal que impide el paso del aire hacia la masa cárnica. Por lo tanto la limpieza de los pistones se realiza alternativamente cada ciclo.This system consists of the provision of a pressurized air inlet connected to the front end of the central tubular duct that runs axially, and through an access plug, so that, when the pistons reach the end of the stroke, the contact drives a solenoid valve causing the exit of the pressurized air that remains until the distributor makes the turning movement. In the general design of the inner core, holes have been made that allow the pressurized air to circulate through them to expel the existing meat mass and drag it through the central tubular duct to the vacuum chamber at the rear end of the machine. This operation is performed on the piston of the cylinder that is completely empty since in this situation the inner core is in a position that prevents the passage of air into the meat mass. Therefore the cleaning of the pistons is performed alternately every cycle.
Además de las mejoras anteriormente mencionadas , la máquina provista de los perfeccionamientos objeto de la invención incorpora unas características que la hacen más eficiente, como es la fijación del núcleo interior con el aro exterior que se realiza a través de una boquilla que permite que el desmontaje sea más rápido y sencillo, realizándose de otra parte las dosificaciones deseadas mediante un temporizador electrónico que para el avance del pistón que extrae la masa del cilindro cada intervalo de tiempo seleccionado.In addition to the aforementioned improvements, the machine provided with the improvements object of the invention incorporates features that make it more efficient, such as fixing the inner core with the outer ring that is made through a nozzle that allows disassembly be faster and simpler, with the desired dosages being carried out by means of an electronic timer that stops the advance of the piston that extracts the mass of the cylinder every selected interval of time.
La máquina propuesta, además de proporcionar un proceso continuo, mejora a las tradicionales embutidoras de pistón, ya que está dotada de un eficaz medio de extracción del aire y unos grandes orificios de entrada y salida que permiten embutir masa con trozos enteros de gran tamaño, siendo por tanto una de las ventajas aportadas, su enorme versatilidad. Al disponer la máquina de un doble pistón en línea, mientras que un pistón embute, simultáneamente el otro carga, consiguiéndose por tal circunstancia, la salida de la masa casi en continuo.The proposed machine, in addition to providing a continuous process, improves on the traditional piston stuffers, since it is equipped with an effective means of extracting the air and large inlet and outlet holes that allow to stuff dough with large whole pieces, being therefore one of the advantages contributed, its enormous versatility. By arranging the machine with a double piston in line, while one piston charges, simultaneously the other load, thus achieving the mass output almost continuously.
La técnica actual contempla la existencia de máquinas embutidoras de acción rotativa, accionadas por paletas, que presentan diversos inconvenientes, uno de ellos la dificultad de eliminación del aire contenido en la masa, otro la reducida capacidad de producción, así como la dificultad de limpieza del interior, y el desmontado de sus partes para reparación. También se conoce la existencia de máquinas embutidoras provistas de pistones hidráulicos de un solo efecto, que en una fase de su recorrido recoge el producto procedente de una tolva, y en la otra fase lo embute después de extraer el aire, reduciendo con este sistema su capacidad de producción.The current technique contemplates the existence of rotary-action stuffing machines, powered by pallets, which present several drawbacks, one of them the difficulty of eliminating the air contained in the dough, another the reduced production capacity, as well as the difficulty of cleaning the interior, and the disassembly of its parts for repair. It is also known the existence of stuffing machines equipped with single-acting hydraulic pistons, which in one phase of its route collects the product coming from a hopper, and in the other phase it embodies it after extracting the air, reducing with this system its production capacity.
La máquina embutidora provista de los perfeccionamientos objeto del presente registro elimina todas las dificultades e inconvenientes existentes en las distintas máquinas descritas en al párrafo anterior, estando constituida por un cuerpo fijo que en su parte superior llevará adosada la tolva de carga, quedando inferiormente fijada al armazón de la máquina; dentro del cuerpo principal y centradamente, se dispone un distribuidor, formado por un cuerpo central solidario de dos cilindros colocados uno a cada lado, disponiendo de unas aberturas que en una posición comunican la tolva con un cilindro y el otro cilindro con la salida del producto, de modo que, mediante un giro del distribuidor, se permite invertir las posiciones descritas con anterioridad.The stuffing machine provided with the improvements object of this register eliminates all the difficulties and inconveniences existing in the different machines described in the previous paragraph, being constituted by a fixed body that will be attached to the loading hopper, being inferiorly fixed to the machine frame; Inside the main body and centered, there is a distributor, formed by a central solidarity body of two cylinders placed one on each side, having openings that in one position communicate the hopper with one cylinder and the other cylinder with the product outlet , so that, by turning the distributor, the positions described above can be reversed.
La parte central del distribuidor dispone también de un orificio centrado, por el que se desliza un tubo axialmente centrado que une los dos pistones, que alternativamente llenan y extraen la masa de los cilindros, estando compuestos los mencionados pistones, de un aro exterior sellado por unas juntas, un núcleo interior y un tope posterior graduable, fijado al aro exterior por medio de una horquilla permitiendo el desmontaje muy rápido y sencillo, estando formado el tope posterior, por una corona roscada y un núcleo interior asimismo roscado, provisto de unas juntas para que no penetre el aire.The central part of the distributor also has a centered hole, through which an axially centered tube that joins the two pistons slides, which alternately fill and extract the mass of the cylinders, said pistons being composed, of an outer ring sealed by gaskets, an inner core and an adjustable rear stop, fixed to the outer ring by means of a fork allowing very fast and simple disassembly, the rear stop being formed, by a threaded crown and an inner threaded core, provided with joints So that the air does not penetrate.
El tubo axial central está unido a los núcleos y al tubo del vastago hidráulico mediante unas piezas de extracción rápida por simple tiro, para el desmontaje y limpieza de todas las partes, y en su movimiento arrastra a los núcleos, produciéndose un deslizamiento respecto a los aros exteriores hasta su total obturación en uno de ellos y la apertura controlada por el tope posterior en el otro, siendo en este caso, cuando por medio de unos orificios o cavidades existentes entre los núcleos y tubo central que comunica con la cámara de vacío, se consigue la extracción del aire contenido en la masa, consiguiéndose la posición descrita, durante la operación de llenado del cilindro, esto es, cuando está en comunicación con la tolva, con lo que se consigue reforzar la succión producida por el pistón y por tanto una mayor compactación de la masa cárnica. El giro del distribuidor es alterno y se efectúa mediante un pistón cremallera con una pieza dentada de arrastre, llevando unos rodamientos radiales y axiales, efectuando el arrastre del distribuidor con la pieza de unión de extracción rápida. El sistema de autolimpiado del circuito de vacío consiste en la disposición de una entrada de aire a presión, conectada al extremo anterior del conducto tubular central que discurre axialmente y a través de un tapón de acceso, de manera que, cuando los pistones llegan al final de carrera, el contacto acciona una electroválvula ocasionando la salida del aire a presión que permanece hasta que el distribuidor realiza el movimiento de giro. En el diseño general del núcleo interior, se han practicado unos orificios que permiten la circulación del aire a presión a través de ellos para expulsar la masa cárnica existente arrastrándola a través del conducto tubular central hasta la cámara de vacío en el extremo posterior de la máquina.The central axial tube is connected to the cores and to the hydraulic rod tube by means of quick-pull parts by simple draft, for the disassembly and cleaning of all parts, and in its movement it drags the cores, producing a sliding with respect to the outer rings until completely sealed in one of them and the opening controlled by the rear stop in the other, being in this case, when through holes or cavities between the cores and central tube that communicates with the vacuum chamber, the extraction of air contained in the mass is achieved, achieving the position described, during the filling operation of the cylinder, that is, when in communication with the hopper, whereby it is possible to reinforce the suction produced by the piston and therefore a greater compaction of the meat mass. The rotation of the distributor is alternate and is carried out by means of a rack piston with a drive gear, carrying radial and axial bearings, dragging the distributor with the quick-release connecting piece. The self-cleaning system of the vacuum circuit consists of the provision of a pressurized air inlet, connected to the front end of the central tubular duct that runs axially and through an access plug, so that when the pistons reach the end of stroke, the contact activates a solenoid valve causing the exit of the pressurized air that remains until the distributor makes the turning movement. In the general design of the inner core, holes have been made that allow the circulation of pressurized air through them to expel the existing meat mass by dragging it through the central tubular duct to the vacuum chamber at the rear end of the machine .
La operación de autolimpiado del circuito de vacío se realiza en el pistón del cilindro que está completamente vacío, ya que en esta actuación el núcleo interior se encuentra en una posición tal que impide el paso del aire hacia la masa cárnica, por lo tanto, la limpieza de los pistones se realiza alternativamente en cada ciclo.The self-cleaning operation of the vacuum circuit is performed on the piston of the cylinder that is completely empty, since in this action the inner core is in a position that prevents the passage of air into the meat mass, therefore, the Piston cleaning is performed alternately in each cycle.
La fijación del núcleo interior con el aro exterior se realiza a través de una boquilla que permite un desmontaje más rápido y sencillo, realizándose de otra parte las dosificaciones deseadas mediante un temporizador electrónico que para el avance del pistón para la extracción de la masa del cilindro cada intervalo de tiempo seleccionado.The fixation of the inner core with the outer ring is carried out through a nozzle that allows a faster and easier disassembly, the desired dosages being carried out by means of an electronic timer that stops the advance of the piston for the extraction of the mass of the cylinder Each selected time interval.
En el proceso de funcionamiento de la máquina provista de los perfeccionamientos que nos ocupan, el pistón impulsado por el cilindro hidráulico que ha retrocedido llenando su cavidad puesto que está en comunicación con la tolva, extrayendo el aire por la cámara de vacío, detiene su trayectoria al llegar a un contacto eléctrico preseleccionado que a su vez acciona una electroválvula, haciendo girar el distribuidor, de forma que la abertura que antes comunicaba con la tolva, se sitúa enfrentada al conducto de salida de la masa, y la parte opuesta al revés, todo ello mediante el pistón cremallera, el cual, al llegar al otro extremo, produce otro contacto eléctrico que mediante otra electroválvula invierte el sentido del movimiento del vastago, haciendo que el núcleo central se desplace introduciendo su parte anterior en el alojamiento interior del aro exterior del pistón, el cual permanece en posición estática debido a la retención ejercida por las juntas, hasta que el resalte del núcleo entra en contacto con la pared del aro exterior, arrastrándolo en su movimiento y produciendo el desalojo de la masa por la correspondiente salida, y simultáneamente el núcleo del pistón opuesto se separa del aro exterior por la razón aducida anteriormente, hasta el tope posterior graduable, momento en que arrastra el aro exterior una vez expedito el paso para extraer el aire, llenando el cilindro con la masa; seleccionando la posición de los contactos eléctricos que limitan el recorrido del cilindro hidráulico, se permite la obtención de las dosificaciones deseadas.In the process of operation of the machine provided with the improvements that occupy us, the piston driven by the hydraulic cylinder that has receded filling its cavity since it is in communication with the hopper, extracting the air through the vacuum chamber, stops its trajectory when arriving at a preselected electrical contact that in turn drives a solenoid valve, rotating the distributor, so that the opening that previously communicated with the hopper, is located facing the outlet duct of the dough, and the opposite side upside down, all through the rack piston, which, upon reaching the other end, produces another electrical contact that by another solenoid valve reverses the direction of the rod movement, causing the central core moves by inserting its front part into the inner housing of the outer ring of the piston, which remains in a static position due to the retention exerted by the seals, until the core protrusion comes into contact with the wall of the outer ring, dragging it in its movement and producing the eviction of the mass by the corresponding exit, and simultaneously the nucleus of the opposite piston separates from the outer ring for the reason stated above, until the adjustable rear stop, at which time it drags the outer ring once expedited the passage to extract the air, filling the cylinder with the mass; By selecting the position of the electrical contacts that limit the travel of the hydraulic cylinder, it is possible to obtain the desired dosages.

Al objeto de facilitar la localización de las diferentes partes que constituyen los perfeccionamientos introducidos en las máquinas embutidoras de productos cárnicos con dosificación continua a que nos venimos refiriendo, se han incorporado acotaciones numéricas en las figuras de los dibujos anexos, relacionadas con las descripciones que de sus características y funcionamientos se realizan a continuación, estando constituida la máquina embutidora por un cuerpo(l), que en su parte superior dispone de forma adosada la tolva de carga(2), todo ello montado por la parte inferior al armazón (3) que constituye el soporte general de la máquina, disponiendo en el centro de un distribuidor giratorio, formado por el núcleo central (4), que forma parte en forma solidaria de dos cilindros situados una por cada lado, teniendo dicha parte central del distribuidor , unas cavidades (5), que en una posición comunican la tolva (2) con un cilindro, mientras que el otro cilindro comunica con la salida (6) del producto, inviniéndose las posiciones descritas con anterioridad, mediante un giro del núcleo central (4) del distribuidor de la máquina. En la parte central del
Figure imgf000008_0001
se encuentra practicado un orificio axial pasante, por el que se desliza el conducto tubular (7) que une los dos pistones que alternativamente llenan y extraen la masa de los cilindros hidráulicos, estando compuestos dichos pistones de un aro exterior (8), sellado por las juntas (9), y un núcleo interior (10), con tope posterior graduable, fijado al aro exterior (8) mediante la horquilla (11) de extracción rápida, incorporando las juntas (12), (13) y (14), evitando la penetración de aire. El conducto tubular (7) está unido a los núcleos (10) y al tubo del vastago hidráulico (15), mediante las piezas (16) y (17), de extracción rápida mediante un simple tiro, para el desmontado y limpieza de las distintas piezas, y en su movimiento arrastra a los núcleos produciéndose un deslizamiento respecto a los aros exteriores hasta su total obturación en uno de ellos y la apertura controlada por el tope posterior en el otro, siendo en este caso, cuando por medio de unos orificios o cavidades practicadas entre el conducto tubular central (7) y los núcleos que comunican dicha apertura con la cámara de vacío (18) se consigue la extracción del aire contenido en la masa, de forma que, la posición descrita se consigue durante la operación de llenado del cilindro, esto es, cuando está en comunicación con la tolva (2), consiguiéndose reforzar la succión producida por el pistón y por tanto una mayor compactación de la masa cárnica.In order to facilitate the location of the different parts that constitute the improvements introduced in the stuffing machines of meat products with continuous dosage to which we have been referring, numerical dimensions have been incorporated in the figures of the attached drawings, related to the descriptions that of its characteristics and operations are then carried out, the filling machine being constituted by a body (l), which in its upper part has the loading hopper (2) attached, all mounted by the lower part to the frame (3) which constitutes the general support of the machine, having in the center of a rotating distributor, formed by the central core (4), which forms part in solidarity with two cylinders located one on each side, said central part of the distributor having some cavities (5), which in one position communicate the hopper (2) with one cylinder, while the other cylinder communicates with the output (6) of the product, reversing the positions described above, by turning the central core (4) of the machine distributor. In the central part of the
Figure imgf000008_0001
a through axial hole is made, through which the tubular duct (7) that joins the two pistons that alternately fill and extract the mass of the hydraulic cylinders slides, said pistons being composed of an outer ring (8), sealed by the joints (9), and an inner core (10), with adjustable rear stop, fixed to the outer ring (8) by means of the quick-release fork (11), incorporating the joints (12), (13) and (14) , avoiding air penetration. The tubular duct (7) is connected to the cores (10) and the tube of the hydraulic rod (15), by means of the parts (16) and (17), of quick extraction by means of a simple shot, for the disassembly and cleaning of the different pieces, and in its movement it drags the cores producing a slide with respect to the outer rings until its total sealing in one of them and the opening controlled by the back stop in the other, being in this case, when through some holes or cavities between the central tubular duct (7) and the cores that communicate said opening with the vacuum chamber (18), the extraction of the air contained in the mass is achieved, so that the position described is achieved during the operation of filling of the cylinder, that is, when it is in communication with the hopper (2), being able to reinforce the suction produced by the piston and therefore a greater compaction of the meat mass.
El giro del núcleo central (4) del distribuidor es alternado y se efectúa mediante el pistón de cremallera (19) conectado al sector periférico dentado (20) practicado en la pieza (21) con interposición de los rodamientos radiales (22) y axiales (23), con la pieza de unión (24) de extracción rápida.The rotation of the central core (4) of the distributor is alternated and is carried out by means of the rack piston (19) connected to the toothed peripheral sector (20) practiced in the part (21) with interposition of the radial (22) and axial bearings ( 23), with the quick-release connection piece (24).
El funcionamiento general de la máquina embutidora provista de los perfeccionamientos de la invención consiste en que cuando el pistón impulsado por el cilindro hidráulico (25) que ha retrocedido llenando su cavidad puesto que está en comunicación con la tolva (2) a través de la correspondiente abertura o cavidad (5), extrayendo el aire contenido, detiene su trayectoria al llegar a un contacto eléctrico preseleccionado (no representado), que a su vez acciona una electroválvula que hace girar el distribuidor (4), encarando la abertura o cavidad (5) que antes comunicaba con la tolva (2), quedando situada frente a la salida (6) para embutir la masa, y en la parte opuesta al revés, mediante el pistón de cremallera (19), el cual al llegar al otro extremo produce otro contacto eléctrico que, mediante otra electroválvula, invierte el sentido del movimiento del vastago (15), haciendo que el núcleo (10) se desplace introduciendo su parte anterior en el alojamiento interior del aro exterior (8) del pistón, el cual permanece estático debido a la retención ejercida por las juntas (9), hasta que el resalte del núcleo entra en contacto con la pared del aro exterior arrastrándolo en su movimiento y produciendo el desalojo de la masa por la salida (6), y simultáneamente el núcleo del pistón opuesto se separa del aro exterior por la razón aducida anteriormente, hasta el tope posterior graduable fijado al aro exterior (8), momento en que arrastra al aro exterior una vez expedito el paso para extraer el aire, llenando el cilindro de masa.The general operation of the stuffing machine provided with the improvements of the invention consists in that when the piston driven by the hydraulic cylinder (25) that has receded filling its cavity since it is in communication with the hopper (2) through the corresponding opening or cavity (5), removing the contained air, stops its trajectory when it reaches a preselected electrical contact (not shown), which in turn drives a solenoid valve that rotates the distributor (4), facing the opening or cavity (5 ) that previously communicated with the hopper (2), being located in front of the outlet (6) to stuff the dough, and on the opposite side upside down, by means of the rack piston (19), which when arriving at the other end produces another electrical contact which, by means of another solenoid valve, reverses the direction of movement of the rod (15), causing the core (10) to move by inserting its front part into the inner housing of the ring outside (8) of the piston, which remains static due to the retention exerted by the seals (9), until the protrusion of the core comes into contact with the wall of the outer ring by dragging it in its motion and causing the mass to be evicted by the outlet (6), and simultaneously the opposite piston core is separated from the outer ring for the reason stated above, up to the adjustable rear stop fixed to the outer ring (8), at which time it drags into the outer ring once the step to extract the air is expedited, filling the mass cylinder.
Dentro de la tolva de entrada del producto (2), se dispone la pieza giratoria (26), en forma de hélice, que bate la masa y la introduce dentro de las cavidades (5) del distribuidor (4), siendo accionada la pieza (26) por medio del grupo moto-reductor (27) en cuyo eje de salida (28) se encuentra montado el piñón (29) , que engrana con la corona dentada (30) fijada al bastidor.Inside the product's input hopper (2), the rotating part (26) is arranged, in the form of a propeller, which beats the dough and introduces it into the cavities (5) of the distributor (4), the part being activated (26) by means of the motor-reducer group (27) on whose output shaft (28) the pinion (29) is mounted, which meshes with the toothed crown (30) fixed to the frame.
El pistón de cremallera (19) permanece alojado dentro del cilindro (31), con las tomas (32),procedentes del circuito hidráulico, para el avance y retroceso de la propia cremallera (19), que produce el volteo alternativo del distribuidor (4) y de los cilindros contenedores de la masa.The rack piston (19) remains housed inside the cylinder (31), with the sockets (32), coming from the hydraulic circuit, for the advance and retraction of the rack itself (19), which produces the alternative turning of the distributor (4 ) and mass container cylinders.
Para evitar que en las operaciones de extracción del aire de la masa se produzcan filtraciones de masa cárnica que puede conllevar a lo largo del tiempo a la obturación de los orificios de los pistones y vastago, reduciendo la eficacia del sistema , se ha introducido un sistema de autolimpiado del circuito de vacío que garantiza el buen funcionamiento del mismo, consistente en una entrada de aire a presión por el conducto tubular anterior (33) conectado axialmente al extremo del conducto tubular (7) a través del tapón de acceso (34), de manera que, cuando los pistones llegan al final de carrera, el contacto acciona una electroválvula ocasionando la salida del aire a presión que permanece hasta que el núcleo central (4) del distribuidor gire. El aire liberado circula a través del tapón (34) y a través del tubo interior (35) hasta el núcleo interior (10) de los pistones. En el propio núcleo interior se le han añadido unos orificios que permiten que el aire a presión circule a través de ellos para expulsar la masa cárnica existente y arrastrarla a través del conducto tubular (7) hasta la cámara de vacío (18), realizándose esta operación en el pistón del cilindro que está completamente vacío, ya que en esta situación, el núcleo interior (10) se encuentra en una posición tal que impide el paso del aire hacia la masa cárnica, por lo que la limpieza de los pistones se realiza alternativamente cada ciclo.To avoid that in the operations of extraction of the air of the mass, filtrations of meat mass occur that can lead over time to the sealing of the holes of the pistons and rod, reducing the efficiency of the system, a system has been introduced of self-cleaning of the vacuum circuit that guarantees its proper functioning, consisting of a pressurized air inlet through the anterior tubular duct (33) axially connected to the end of the tubular duct (7) through the access plug (34), so that when the pistons reach the end of the stroke, the contact activates a solenoid valve causing the exit of the pressurized air that remains until the central core (4) of the distributor rotates. The released air circulates through the cap (34) and through the inner tube (35) to the inner core (10) of the pistons. In the inner core itself, holes have been added that allow the pressurized air to circulate through them to expel the existing meat mass and drag it through the tubular duct (7) to the vacuum chamber (18), making it operation in the piston of the cylinder that is completely empty, since in this situation, the inner core (10) is in a position that prevents the passage of air into the meat mass, so that the cleaning of the pistons is carried out alternately every cycle.
