DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se encuadra en el campo técnico de la industria alimentaria y más concretamente en la industria de las conservas de pescado, donde el pescado se somete a diferentes etapas transformadoras antes de su envasado y distribución entre los consumidores finales. The present invention falls within the technical field of the food industry and more specifically in the canned fish industry, where the fish is subjected to different processing stages before packaging and distribution among final consumers.
Más concretamente esta invención se refiere a una instalación y a un procedimiento de procesado en continuo de túnidos y similares con un peso de hasta 10 kg, ya que para túnidos o similares de mayor peso se utilizan otras técnicas diferentes de procesado, así como la mano de obra influye de un menor modo sobre el costo final del producto. More specifically, this invention relates to an installation and a process for the continuous processing of tunas and the like with a weight of up to 10 kg, since other different processing techniques are used for tuna or similar ones of greater weight, as well as the hand of work influences in a minor way on the final cost of the product.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los túnidos son un género de peces o pescado muy popular en la alimentación mundial desde tiempos ancestrales, por su alto contenido nutritivo. Dentro de este género se distinguen numerosas especies que pueden llegar hasta los 3 metros y cerca de los 900 Kg. Tunas are a genus of fish or fish very popular in world food since ancient times, because of its high nutritional content. Within this genus numerous species are distinguished that can reach up to 3 meters and about 900 Kg.
Entre los túnidos destacan un considerable conjunto de especies entre las que se encuentra la caballa, el estornino, la melva, la bacoreta, el atún listado, el bonito y los grandes atunes rojos, teniendo una variedad de tamaños muy diversos que los hace diferenciarse además de su sabor y aspecto, en su modo de procesamiento. Among the tunas, a considerable set of species stands out, including mackerel, starling, melva, bacoreta, tuna, bonito and large bluefin tuna, having a variety of very different sizes that makes them differentiate of its taste and appearance, in its processing mode.
Aunque estos pescados pueden ser procesados frescos, el método más habitual en la industria conservera consiste en la cocción de estos productos y envasado de los mismos con aceites vegetales, escabeches u otros líquidos que preservan las cualidades de dichos productos.
Para llevar a cabo estas operaciones, el pescado suele llegar congelado desde cámaras frigoríficas existentes en tierra firme o provienen de barcos congeladores, procesándose mediante la cocción de los mismos y posteriormente de forma manual se retira por parte de operarios, las escamas, cabeza, se retiran los lomos, la espina y se limpian los lomos antes de su envasado. Cuando se trata de pescados de gran tamaño, el rendimiento de estas operaciones es bastante elevado porque el contenido de carne extraído de estos grandes atunes por encima de los 10 Kg es elevado y por tanto la mano de obra empleada es compensada por el precio de la materia prima que se procesa. El problema reside en el procesamiento de túnidos o pescados con un peso inferior a los 10 Kg. ya que el rendimiento en el procesamiento es más bajo de los operarios ya que no es tanta la producción de carne por parte de los operarios, lo que lleva a que el precio del procesado de estos pescados se eleve de una forma inusitada y es lo que ha provocado que muchas industrias pesqueras desviasen el procesado de este tipo de pescados a países subdesarrollados o en vías de desarrollo, donde la mano de obra es más barata y por tanto su incidencia en el procesado del pescado hace que no se eleve el precio final de las conservas. Although these fish can be processed fresh, the most common method in the canning industry is the cooking of these products and packaging them with vegetable oils, marinades or other liquids that preserve the qualities of these products. To carry out these operations, the fish usually arrives frozen from existing cold stores on the mainland or from freezer ships, processed by cooking them and then manually removed by operators, scales, head, Remove the loins, the spine and clean the loins before packing. When it comes to large fish, the performance of these operations is quite high because the content of meat extracted from these large tunas above 10 Kg is high and therefore the labor used is compensated by the price of the raw material that is processed. The problem lies in the processing of tuna or fish weighing less than 10 kg, since the processing performance is lower than the operators since the production of meat by the operators is not so much, which leads to the fact that the price of the processing of these fish rises in an unusual way and that is what has caused many fishing industries to divert the processing of this type of fish to underdeveloped or developing countries, where labor is cheaper and therefore its impact on fish processing does not raise the final price of canned food.
Se conoce la patente española ES-2543030 del mismo solicitante consistente en una instalación y un procedimiento automatizados para procesar túnidos y similares, donde tales pescados una vez pelados son cocidos, descabezados y separados los lomos de la espina para posteriormente ser envasados en conserva los lomos o las distintas partes de los lomos de los pescados. The Spanish patent ES-2543030 of the same applicant is known, consisting of an automated installation and procedure to process tunas and the like, where such fish, once peeled, are cooked, decapitated and separated the spine loins to later be packaged in canned loins. or the different parts of the loins of the fish.
La patente española ES-2350079 divulga un dispositivo de tratamiento de pescado con una primera estación de colocación o entrada de ejemplares, una segunda estación de pelado sobre la cual el pescado se sitúa en un elemento posicionador, una tercera estación de corte y separación de la espina central cortando el pescado en dos mitades mediante chorro de agua, la vez que una pinza coge la espina y la separa de los lomos que caen sobre sendas cintas de transporte. Spanish patent ES-2350079 discloses a fish treatment device with a first station for the placement or entry of specimens, a second peeling station on which the fish is placed in a positioning element, a third station for cutting and separating the fish. central spine cutting the fish in two halves by means of water jet, the same time that a clamp picks up the spine and separates it from the loins that fall on two conveyor belts.
Es propósito de la invención conseguir una instalación y un procedimiento de procesamiento de túnidos o similares con un peso inferior a los 10 kg, donde se sustituya la mano de obra por un sistema automatizado de procesado de pescado que evite el sobrecosto de dicha mano de obra sobre las conservas.
Es también propósito de la invención una instalación y un procedimiento que separe los residuos líquidos y/o sólidos para su reciclado, filtrado y reutilización o reutilización mediante valorizado del producto. It is the purpose of the invention to achieve an installation and a process for processing tunas or the like weighing less than 10 kg, where labor is replaced by an automated fish processing system that avoids the cost overrun of said labor. about canned food It is also the purpose of the invention an installation and a method that separates liquid and / or solid waste for recycling, filtering and reuse or reuse through product recovery.

La presente invención consiste en una instalación y un procedimiento de procesado en continuo de túnidos y similares que permite el procesamiento de túnidos y similares con un peso inferior a los 10 Kg. que es el tamaño en los que su mano de obra influye en gran medida sobre el precio del producto final, ya que el rendimiento de producto obtenido es menor. The present invention consists of an installation and a process of continuous processing of tunas and the like that allows the processing of tunas and the like with a weight less than 10 Kg. Which is the size in which their workforce greatly influences on the price of the final product, since the yield of product obtained is lower.
La instalación de procesado en continuo de túnidos y similares de la invención comprende: The installation of continuous processing of tunas and the like of the invention comprises:
- Una zona de entrada de producto a procesar, donde el producto se mantiene a la espera de su procesamiento. Habitualmente los productos a procesar provienen de cámaras de congelación a -10°C donde el producto a tratar es conservado durante un tiempo prudencial antes de su procesado. En esta zona de entrada, optativamente se puede insertar a los túnidos una sonda inalámbrica que permite monitorizar la temperatura dentro del túnido cuando esté siendo sometido a la cocción. - A product entry area to be processed, where the product is kept awaiting processing. Usually the products to be processed come from freezing chambers at -10 ° C where the product to be treated is kept for a reasonable time before processing. In this input zone, a wireless probe can optionally be inserted into the tunas that allows monitoring the temperature inside the tuna when it is being cooked.
- Una zona de procesado intermedio del producto, que comprende - An intermediate processing zone of the product, which comprises
- Una primera etapa de clasificación del producto por tamaño y/o peso - A first stage of product classification by size and / or weight
- Una segunda etapa de carga del producto clasificado, en al menos una línea independiente de procesado del producto, y donde cada línea independiente de procesado del producto, hace pasar el mismo por - A second stage of loading the classified product, in at least one independent product processing line, and where each independent product processing line, passes it through
- Una primera fase de prelavado del producto - A first phase of product prewash
- Una segunda fase de escaldado del producto - A second phase of scalding of the product
- Una tercera fase de pelado del producto - A third phase of product peeling
- Una cuarta fase de cocción del producto - A fourth phase of product cooking
- Una quinta fase de enfriamiento del producto - A fifth phase of product cooling
En donde estas fases se efectúan en un recinto aislado, donde la línea de procesado efectúa un recorrido sinuoso en altura, ascendiendo y descendiendo el producto, y dividiéndose el recorrido en zonas mediante tabiques separadores verticales.
- Una zona de procesado final, donde el producto una vez lavado, pelado y cocido se conduce al descabezado del producto, apertura de los lomos, retirada de la espina y limpieza de los lomos obtenidos para su posterior almacenamiento o envasado. Where these phases are carried out in an isolated enclosure, where the processing line makes a sinuous route in height, ascending and descending the product, and dividing the route into zones by means of vertical separating partitions. - A final processing area, where the product once washed, peeled and cooked is led to the product decapitation, opening of the loins, removal of the spine and cleaning of the loins obtained for later storage or packaging.
En la etapa de clasificación del producto por tamaño y/o peso, cuenta con medios de pesada individualizada del producto o medios de separación por tamaño del producto, que agrupa de modo homogéneo los productos, así como incluye medios de transferencia de los productos separados por pesos y/o tamaños a las diferentes líneas de procesado de la etapa de carga del producto. Los medios de transferencia de los productos separados, consisten en un brazo robotizado que recoge individualizadamente cada producto y lo deposita en los moldes de las líneas de procesado, aunque se podría disponer de cualquier otro tipo de clasificador de productos formado por una cinta transportadora y diferentes compuestas que abren o cierran el paso a las diferentes ubicaciones donde son agrupados los productos por su peso o por sus dimensiones. In the stage of classification of the product by size and / or weight, it has means of individualized weighing of the product or means of separation by product size, which homogeneously groups the products, as well as includes means of transfer of the products separated by weights and / or sizes at the different processing lines of the product loading stage. The means of transfer of the separated products, consist of a robotic arm that collects each product individually and deposits it in the molds of the processing lines, although any other type of product classifier formed by a conveyor belt and different Compounds that open or close the passage to the different locations where the products are grouped by weight or size.
Las líneas de procesado de producto se disponen en un numero variable de ellas y por tanto se dispondrá de tantas líneas de procesado como tamaños de separación de productos homogéneos se realicen, teniendo cada línea de procesado medios de accionamiento independientes, que permitirán variar la velocidad del proceso de los túnidos o similares. The product processing lines are arranged in a variable number of them and therefore there will be as many processing lines as separate sizes of homogeneous products are made, each processing line having independent drive means, which will allow to vary the speed of the tuna or similar process.
Entre la zona de entrada del producto a procesar y la zona de procesado final, se dispone de una zona de procesado intermedio del producto, donde las líneas de procesado discurren paralelamente entre sí, hacen un recorrido sinuoso en altura y se divide esta zona de procesado mediante tabiques separadores que separan los diferentes procesos a realizar sobre el producto. Este recorrido sinuoso en altura permite una adaptación de la maquinaria al proceso, por lo que si se necesita un mayor recorrido de las fases de prelavado, escaldado, pelado, cocción o enfriamiento, solo se requerirá la elevación de la altura de la instalación y por tanto del recorrido de las líneas de procesado sin que ello repercuta sobre las dimensiones en planta de la instalación. La independencia del accionamiento de las líneas facilita la adaptación de la velocidad de proceso de los túnidos o similares a la propia
instalación, así por ejemplo en túnidos pequeños la velocidad que se puede dar a la línea puede ser mayor, ya que la cocción y enfriamiento de las piezas cocidas, al tener un tamaño menor, se puede efectuar en menos tiempo en comparación a si se tratase de piezas de mayor tamaño, por tanto si se dispone de varias líneas de procesado lo normal es que cada línea lleve una velocidad diferente adaptada las piezas de pescado, ya que aquellas de pescados más grandes tendrán velocidades menores y las líneas que soporten pescados más pequeños podrán ir a mayores velocidades de proceso, todo ello influenciado con la etapa de cocción y enfriamiento del pescado. Between the entrance zone of the product to be processed and the final processing zone, there is an intermediate processing zone of the product, where the processing lines run parallel to each other, make a winding route in height and divide this processing zone through separating partitions that separate the different processes to be carried out on the product. This winding route in height allows an adaptation of the machinery to the process, so if a longer route of the prewash, blanching, peeling, cooking or cooling phases is needed, only the installation height elevation will be required and by both of the route of the processing lines without this having an impact on the plant dimensions of the installation. The independence of the drive of the lines facilitates the adaptation of the process speed of the tunas or similar to the own one installation, for example in small tunas the speed that can be given to the line can be greater, since the cooking and cooling of the cooked pieces, having a smaller size, can be done in less time compared to if it were treated of larger pieces, therefore if several processing lines are available, it is normal for each line to have a different speed adapted to the pieces of fish, since those of larger fish will have lower speeds and the lines that support smaller fish They can go at higher process speeds, all influenced by the cooking and cooling stage of the fish.
La zona de procesado intermedio comprende una primera fase de prelavado del producto, sobre el cual se inyecta agua mediante boquillas aspersoras que arrastran la suciedad que pudieran portar tales productos, una segunda fase de escaldado del producto mediante la proyección de agua caliente sobre la superficie del producto que facilite la retirada de la piel, una tercera fase de pelado del producto mediante el contacto de cepillos sobre la superficie del producto con la consiguiente retirada de la piel, una cuarta fase de cocción del producto pelado mediante la aplicación de vapor a través de boquillas a lo largo de la zona de cocción y una quinta fase de enfriamiento del producto mediante la proyección de agua hacia el producto, antes de su paso a la zona de procesado final. The intermediate processing zone comprises a first phase of pre-washing of the product, on which water is injected by spray nozzles that carry away the dirt that such products may carry, a second phase of scalding of the product by spraying hot water on the surface of the product that facilitates the removal of the skin, a third phase of peeling of the product by brush contact on the surface of the product with the consequent removal of the skin, a fourth phase of cooking of the peeled product by applying steam through nozzles along the cooking zone and a fifth phase of cooling of the product by spraying water to the product, before passing to the final processing area.
En la parte inferior de la zona de procesado intermedio, se disponen bandejas de recogida de residuos sólidos y/o líquidos, coincidentes con las fases de prelavado, escaldado, pelado, cocción y enfriamiento del producto, residuos que son individualmente tratados para su reciclado o valorización. Así por ejemplo las bandejas que recogen residuos líquidos procedentes de las fases de cocción y enfriamiento, se trataría de residuos de alto contenido proteico, líquidos que pueden ser filtrados y condensados para su utilización en otras industrias o ser vendidos como productos valorizados. Sin embargo los residuos procedentes de la limpieza, escaldado y pelado de estos pescados, normalmente carecen de ese alto valor proteico, por lo que normalmente se procede a una separación de sólidos y líquidos, para ser los sólidos desechados mientras que los líquidos una vez filtrados pueden ser reutilizados nuevamente como aguas de limpieza de los productos con el consiguiente ahorro de agua y energético de la instalación.
Es también objeto de la invención un procedimiento de procesado en continuo de túnidos y similares que comprende. In the lower part of the intermediate processing area, solid and / or liquid waste collection trays are arranged, coinciding with the prewash, blanching, peeling, cooking and cooling phases of the product, waste that is individually treated for recycling or valorization. Thus, for example, the trays that collect liquid waste from the cooking and cooling phases, would be high protein waste, liquids that can be filtered and condensed for use in other industries or sold as valued products. However, the residues from the cleaning, scalding and peeling of these fish, normally lack that high protein value, so that a separation of solids and liquids is normally carried out, to be the discarded solids while the liquids once filtered they can be reused again as cleaning waters of the products with the consequent saving of water and energy of the installation. It is also the object of the invention a process of continuous processing of tunas and the like comprising.
- separación del producto por tamaño y/o peso homogéneo - product separation by size and / or homogeneous weight
- transferencia de los productos homogéneos separados hacia líneas continuas de procesado independiente - transfer of separate homogeneous products to continuous lines of independent processing
- donde cada línea continua de procesado independiente hace un recorrido sinuoso en altura donde el producto se somete a un prelavado, escaldado, pelado, cocción y enfriamiento. - where each continuous line of independent processing makes a sinuous route in height where the product is subjected to a prewash, blanching, peeling, cooking and cooling.
- el producto finalmente se descabeza, se abren los lomos, se retira la espina y se limpian ambos lomos antes del envasado o almacenado de los mismos. - The product is finally decapitated, the spines are opened, the spine is removed and both spines are cleaned before packaging or storage.
En este proceso, los restos líquidos y/o solidos procedentes de las fases de prelavado, escaldado, pelado, cocción y enfriamiento del producto son retirados de forma controlada para su reciclado y/o reutilización durante el proceso. Los residuos líquidos procedentes de las etapas de cocción y enfriamiento del producto de alto contenido proteico son retirados como producto valorizado, mientras que los residuos líquidos y sólidos procedentes de las fases de prelavado, escaldado y pelado del producto son filtrados, siendo la fase liquida apta para su reutilización nuevamente en dicho proceso, mientras que los restos solidos son retirados para su posterior reciclado. In this process, the liquid and / or solid remains from the prewash, blanching, peeling, cooking and cooling phases of the product are removed in a controlled manner for recycling and / or reuse during the process. The liquid residues from the cooking and cooling stages of the high protein product are removed as a recovered product, while the liquid and solid residues from the prewash, blanched and peeled phases of the product are filtered, the liquid phase being suitable for reuse again in said process, while the solid remains are removed for later recycling.
La transferencia de los productos homogéneos separados hacia líneas continuas de procesado independiente se realiza mediante un brazo robotizado que recoge individualizadamente cada producto y lo deposita en los moldes de las líneas de procesado, o bien se pueden emplear cualquier otro medio de distribución de los túnidos o similares en las líneas de proceso, distribución que dependerá del tamaño y dimensiones de los mismos y por tanto cada línea de procesamiento procesará peces de una homogénea morfología y peso. Las líneas de procesado en continuo del producto discurren de forma paralela con accionamientos y velocidades independientes, adaptadas tales velocidades a los productos a tratar, ya que los tiempos de cocción y enfriamiento variarán dependiendo del tamaño de los pescados. The transfer of the separated homogeneous products to continuous lines of independent processing is carried out by means of a robotic arm that individually collects each product and deposits it in the molds of the processing lines, or any other means of distribution of the tuna can be used or similar in the process lines, distribution that will depend on their size and dimensions and therefore each processing line will process fish of a homogeneous morphology and weight. The continuous processing lines of the product run in parallel with independent drives and speeds, such speeds adapted to the products to be treated, since cooking and cooling times will vary depending on the size of the fish.
Una vez que los túnidos o similares atraviesan la zona de procesado intermedio, los mismos se desplazan a la zona de procesado final del producto, zona en la cual el
producto se descabeza, se abren los lomos, se separa la espina del pescado y se procede a la limpieza de tales lomos, operaciones que se llevan a cabo en una instalación como la de la patente ES-2543030, donde el producto una vez cocido y pelado es descabezado y separados los lomos con la ayuda de unas bayonetas que se clavan en los lomos y que con un movimiento de separación logran separar entre si ambos lomos y se facilita el acceso a la espina central para su retirada del pescado. Once the tunas or the like cross the intermediate processing zone, they move to the final processing zone of the product, zone in which the The product is decapitated, the spines are opened, the spine is separated from the fish and the loins are cleaned, operations that are carried out in an installation such as that of the ES-2543030 patent, where the product once cooked and Peeled is decapitated and the loins separated with the help of bayonets that are nailed in the loins and that with a separation movement manage to separate both loins from each other and facilitates access to the central spine for removal of the fish.

DESCRIPCIÓN DE UN MODO PREFERENTE DE REALIZACIÓN DE LA INVENCIÓN DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
En la figura 1 se observa una vista en perspectiva de una instalación como la reivindicada en la presente invención, donde se pueden distinguir, una zona de entrada de producto a procesar (1), una zona de procesado intermedio del producto (2) y una zona de procesado final del producto (3). Figure 1 shows a perspective view of an installation as claimed in the present invention, where it is possible to distinguish, an inlet zone of the product to be processed (1), an intermediate processing zone of the product (2) and a final product processing zone (3).
Centrándonos en la zona de entrada de producto a procesar (1), se observa cómo llegan los túnidos o similares en cestas (4) donde estos túnidos llegan congelados a una temperatura cercana a los -10°C, donde un operario (5) deposita el pescado sobre una cinta transportadora (6) que lo transfiere a la etapa de clasificación (7) del
producto por tamaño y/o peso. En esta zona 1 se incluye, en una forma preferente de realización de la instalación, la inserción de una sonda inalámbrica en el cuerpo de los túnidos que permite conocer el dato de la temperatura en el interior del pescado en el momento de la cocción y así ajustar los parámetros y condiciones dentro de la etapa de cocción para que no se sobrepase el proceso de cocción del mismo. Estas sondas transmiten a una unidad central los valores de temperaturas y así ser más preciso con la cocción de los pescados. Focusing on the area of entry of the product to be processed (1), it is observed how tuna or similar arrive in baskets (4) where these tuna arrive frozen at a temperature close to -10 ° C, where an operator (5) deposits the fish on a conveyor belt (6) that transfers it to the classification stage (7) of the product by size and / or weight. This zone 1 includes, in a preferred embodiment of the installation, the insertion of a wireless probe in the body of the tunas that allows to know the temperature data inside the fish at the time of cooking and thus adjust the parameters and conditions within the cooking stage so that the cooking process is not exceeded. These probes transmit the temperature values to a central unit and thus be more precise with the cooking of the fish.
A continuación, un brazo robotizado (8) transfiere el pescado clasificado homogéneamente sobre las líneas de procesado, no visibles en esta figura, pasando a la zona de procesado intermedio (2). Next, a robotic arm (8) transfers the fish classified homogeneously over the processing lines, not visible in this figure, passing to the intermediate processing zone (2).
En esta zona de procesado intermedio (2), se observa un recinto cerrado (9) de una gran altura, por el que discurren las líneas de procesado y donde el pescado se somete a las fases sucesivas de limpieza, escaldado, pelado, cocción y enfriado del pescado, haciendo esas líneas de procesado un recorrido sinuoso en altura para ganar espacio en su superficie proyectada en planta. Con las referencias (10) y (1 1) se muestran tanques de filtrado y recuperación de residuos líquidos para su reutilización en el proceso y en el tanque (12) se realiza la recuperación de líquidos procedentes de las fases de cocción y enfriado que son de alto contenido proteico y que por sí mismo es considerado como un producto valorizable. In this intermediate processing zone (2), a closed enclosure (9) of a great height is observed, through which the processing lines run and where the fish is subjected to the successive phases of cleaning, scalding, peeling, cooking and cooled the fish, making those processing lines a winding path in height to gain space on its projected surface in the plant. With the references (10) and (1 1), filtration and recovery tanks of liquid waste are shown for reuse in the process and in the tank (12) the recovery of liquids from the cooking and cooling phases that are high protein content and that by itself is considered as a valuable product.
Finalmente a la salida de la zona de procesado intermedio (2) se encuentra la zona de procesado final (3), donde el producto se somete a un descabezado, apertura de los lomos, retirada de la espina y limpieza de los lomos (13), que son retirados por la cinta transportadora (14) para su envasado o almacenamiento. Esta zona de procesado final podría ser como la que describe la patente española del mismo solicitante ES-2543030 y que se ha mencionado en los antecedentes de la invención. En la figura 2 se muestra una vista en sección detallada de la instalación de procesado en continuo de túnidos y similares de la invención. De izquierda a derecha en la citada figura se observan las tres zonas en las que se divide la instalación de procesado continuo, consistentes en la zona de entrada de producto a procesar (1), la zona de procesado intermedio del producto (2) y la zona de procesado final del producto (3).
En la zona de entrada de producto a procesar (1) se observa la cinta transportadora (6) de producto entrada y los pescados (15) como entran en el proceso, normalmente congelados a una temperatura próxima a los -10°C, aunque no se descarta la entrada de pescado fresco a la instalación. Finally, at the exit of the intermediate processing zone (2) there is the final processing zone (3), where the product is subjected to a decapitation, opening of the spines, removal of the spine and cleaning of the loins (13) , which are removed by the conveyor belt (14) for packaging or storage. This final processing area could be as described in the Spanish patent of the same applicant ES-2543030 and mentioned in the background of the invention. A detailed sectional view of the continuous tuna processing facility and the like of the invention is shown in Figure 2. From left to right in the aforementioned figure we can see the three zones in which the continuous processing installation is divided, consisting of the zone of entry of the product to be processed (1), the zone of intermediate processing of the product (2) and the final product processing zone (3). In the zone of entry of the product to be processed (1) the conveyor belt (6) of the incoming product and the fish (15) are observed as they enter the process, normally frozen at a temperature close to -10 ° C, although not the entrance of fresh fish to the installation is discarded.
Estos pescados (15) son clasificados por tamaños y pesos en grupos homogéneos de pescados para su tratamiento posterior más homogéneo. Estos pescados son transferidos mediante un brazo robotizado (8) hacia la zona de procesado intermedio (2). These fish (15) are classified by sizes and weights in homogeneous groups of fish for their more homogeneous subsequent treatment. These fish are transferred by means of a robotic arm (8) to the intermediate processing zone (2).
En esta zona de procesado intermedio (2) se encuentra representada la línea de procesado continuo (16), que va desde la zona de carga (17) hasta la zona de procesado final (3), para lo cual esta línea de procesado continuo (16) se constituye mediante una cadena continua que pasa a través de ruedas dentadas (18) que efectúan el guiado de la cadena, acoplándose a la cadena, moldes (19) de la línea de procesado, donde se depositan los pescados a tratar. En estos moldes (19) son depositados los pescados (15) por el brazo robotizado (8). In this intermediate processing zone (2) the continuous processing line (16) is represented, which goes from the loading zone (17) to the final processing zone (3), for which this continuous processing line ( 16) is constituted by a continuous chain that passes through cogwheels (18) that guide the chain, coupling to the chain, molds (19) of the processing line, where the fish to be treated are deposited. In these molds (19) the fish (15) are deposited by the robotic arm (8).
La línea de procesado (16) hace un recorrido sinuoso de subida y bajada de la línea mediante el uso de ruedas dentadas (18) desviadoras del sentido de la cadena de transporte y los pescados (15) pasan por una primera fase de lavado, escaldado y pelado en (20), fase que se realiza mediante la proyección de agua sobre los pescados, seguido de una proyección de agua hirviendo sobre los pescados en la fase de escaldado y retirada de la piel mediante la actuación de cepillos mecánicos, para a continuación y una vez pelados los pescados, continuar a la segunda fase de cocción (21) mediante la inyección de vapor de agua o agua calentada que provocara la cocción de los pescados según discurren a través del recorrido sinuoso de la línea de procesado continuo (16). Una vez superada la fase de cocción se llega a la fase de enfriamiento final del producto mediante la inyección de agua fría que hace bajar la temperatura del producto. The processing line (16) makes a sinuous route of raising and lowering the line through the use of sprockets (18) deviating from the direction of the transport chain and the fish (15) go through a first phase of washing, scalding and stripped in (20), a phase that is carried out by spraying water on the fish, followed by a projection of boiling water on the fish in the scalding phase and removing the skin by means of mechanical brushes, then and once the fish is peeled, continue to the second cooking phase (21) by injecting steam or heated water that will cause the fish to cook as they run through the winding path of the continuous processing line (16) . Once the cooking phase is over, the final cooling phase of the product is reached by injecting cold water that lowers the product temperature.
En la parte inferior de esta zona de procesado, se encuentran las bandejas de recogida de residuos sólidos y/o líquidos (23), donde las aguas procedentes del lavado, escaldado y pelado del producto serán filtradas para su ulterior utilización,
mientras que los líquidos procedentes de la zona de cocción y enfriamiento de alto contenido proteico pueden ser valorizados. In the lower part of this processing area, are the solid and / or liquid waste collection trays (23), where the water from washing, scalding and peeling the product will be filtered for further use, while liquids from the high protein cooking and cooling zone can be recovered.
La línea de procesado continuo (16) continua en la zona de procesado final (3) donde los pescados (15) ya cocidos se procede al descabezado (24), apertura de los lomos y extracción de la espina (25), cepillado de los lomos (26), enfriado de los lomos (27) y zona de entrega de los lomos abiertos (28) hacia la cinta transportadora (14) de salida, donde los lomos del producto (13) son retirados. The continuous processing line (16) continues in the final processing area (3) where the fish (15) already cooked proceeds to the decapitation (24), opening the loins and extracting the spine (25), brushing the Loins (26), cooling of the loins (27) and delivery area of the open loins (28) to the exit conveyor belt (14), where the loins of the product (13) are removed.
En la zona inferior de esta zona de procesado final (3) se disponen de recipientes (29) de recogida de restos no útiles, como la cabeza, y espinas del pescado que serán en otras fases desechados o enviados para su reciclado en otro tipo de productos. In the lower zone of this final processing zone (3) there are containers (29) for the collection of non-useful remains, such as the head, and fish bones that will be discarded or sent for recycling in other types of waste. products.
En la figura 3 se muestra en detalle del dispositivo utilizado para la fase de cocción de los túnidos, mostrándose en esta figura una parte de dicho dispositivo que se incorpora en la línea de procesado. Se dispone de una tubería de vapor (30) con su correspondiente válvula de accionamiento para vapor (32) y una segunda tubería de agua (31) que conlleva la correspondiente válvula de accionamiento de agua (33). Tanto las tuberías de vapor como la tubería de agua tienen unas salidas a diferentes alturas que confluye en unas boquillas (34) donde las tuberías de agua a su salida acaban en unos atomizadores (35) que pulverizan agua y se entremezclan con el vapor que sale de las tuberías 30, produciendo una mezcla de vapor y gotas de agua pulverizada que controlan la temperatura del vapor que se proyectará sobre los túnidos, para evitar que el vapor pueda quemarlos. Figure 3 shows in detail the device used for the tuna cooking phase, showing in this figure a part of said device that is incorporated into the processing line. There is a steam pipe (30) with its corresponding steam actuation valve (32) and a second water pipe (31) that carries the corresponding water actuation valve (33). Both the steam pipes and the water pipe have exits at different heights that converge in nozzles (34) where the water pipes at their exit end in atomizers (35) that spray water and intermingle with the steam that comes out of the pipes 30, producing a mixture of steam and drops of water spray that control the temperature of the steam that will be projected on the tunas, to avoid that the steam can burn them.
A la salida de estas boquillas (34) se emplea un dispositivo que se denomina acople de turbulencias (36), similar a un cuerpo espiral que provoca, que el vapor y agua pulverizada que arrastra no incida con presión en el cuerpo del pescado, así como lo hace de forma turbulenta tipo abanico que abarque de forma suave toda la superficie del pescado a la misma temperatura y sin presión, resultando una cocción homogénea del pescado que discurre por el interior de la línea de procesamiento.
Este dispositivo se coloca en la zona de cocción dentro del recinto cerrado (9) entre la línea de procesado continuo, incluyendo este dispositivo diferentes boquillas (34) separadas entre sí a intervalos adecuados, para producir una cocción homogénea de los pescados cuando atraviesan el recinto cerrado (9) hasta su salida del mismo.
At the exit of these nozzles (34) a device called turbulence coupling (36) is used, similar to a spiral body that causes, that the steam and water spray that it drags does not affect the body of the fish with pressure, so as it does in a turbulent fan type that smoothly covers the entire surface of the fish at the same temperature and without pressure, resulting in a homogeneous cooking of the fish that runs through the interior of the processing line. This device is placed in the cooking zone inside the enclosed enclosure (9) between the continuous processing line, this device including different nozzles (34) separated from one another at appropriate intervals, to produce a homogeneous cooking of the fish when they cross the enclosure. closed (9) until its exit.
