CAMISA PRE-ENFRIADORA DE AGUA PARA MAQUINA  WATER PRE-CHILLER SHIRT FOR MACHINE
DE FABRICACIÓN DE HIELO DEL TIPO VERTICAL-MULTITUBULAR  ICE MANUFACTURING OF THE VERTICAL-MULTI-TUBULAR TYPE
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
Es objeto de la presente invención, tal y como el título de la misma establece, incorporar en el diseño de los fabricadores de hielo del tipo vertical-multitubular una camisa exterior o camisa pre-enfriadora para recircular el agua que posteriormente se usará para fabricar el hielo. It is object of the present invention, as the title of the same establishes, to incorporate in the design of the ice makers of the vertical-multitubular type an outer jacket or pre-chilling jacket to recirculate the water that will later be used to manufacture the ice.
Caracteriza a la presente instalación, el hecho de dotar a las máquinas para fabricación de hielo de este tipo una configuración y geometría tal que mejora el rendimiento energético del conjunto de la instalación aprovechando las perdidas de frío que estas máquinas tienen en su superficie exterior para enfriar el agua de entrada a los tubos encargados de la fabricación del hielo. The present installation characterizes the fact of equipping the ice making machines of this type with a configuration and geometry such as to improve the energy efficiency of the installation as a whole, taking advantage of the cold losses that these machines have on their exterior surface to cool the entrance water to the tubes responsible for the manufacture of ice.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de las máquinas del tipo vertical-multitubular para fabricación de hielo. Therefore, the present invention is circumscribed within the scope of machines of the vertical-multitubular type for ice making.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El uso del hielo está en aumento, sobre todo debido a la demanda de bebidas, teniendo mercado tanto en hostelería, como en las cadenas de distribución. The use of ice is increasing, mainly due to the demand for beverages, having a market in the hotel and retail chains.
En las instalaciones para fabricar hielo tipo vertical-multitubular, éstas cuentan con una serie de tubos verticales por los que circula el agua, y que están inmersos en un gas refrigerante que produce la congelación del agua dentro de cada tubo, a continuación, se someten a los tubos a un golpe de calor que provoca que el hielo formado dentro del tubo y que tiene forma de cilindro se suelte por la tubería donde se ha creado y pasa a una cortadora que lo corta al tamaño deseado. In vertical-multitubular ice making facilities, these have a series of vertical tubes through which the water circulates, and which are immersed in a refrigerant gas that produces the freezing of water inside each tube, then they are submitted to the tubes to a heat stroke that causes the ice formed inside the tube and that has the shape of a cylinder to be released by the pipe where it was created and passes to a cutter that cuts it to the desired size.
Sin embargo, la camisa o virola por cuyo interior discurre el gas refrigerante, está en su parte exterior directamente en contacto con el aire que la rodea, lo que supone un intercambio de calor con el medio exterior que no es aprovechado, estando dicha camisa o virola sin aislante alguno, produciendo en consecuencia una pérdida de energía y una disminución del rendimiento de la máquina. However, the sleeve or ferrule through which the cooling gas runs, is on its outer part directly in contact with the air that surrounds it, which involves an exchange of heat with the external environment that is not used, said shirt being or ferrule without any insulation, consequently producing a loss of energy and a decrease in the performance of the machine.
Por lo tanto, es objeto de la presente invención mejorar las máquinas para fabricar hielo de este tipo aprovechando la pérdida energética del gas refrigerante al estar en contacto directo con el medio exterior, desarrollando una camisa como la que a continuación se describe y queda recogida en su esencialidad en la reivindicación primera. Therefore, it is an object of the present invention to improve the ice making machines of this type by taking advantage of the energy loss of the refrigerant gas when in direct contact with the external environment, developing a jacket as described below and collected in its essentiality in the first claim.
DESCRIPCIÓN DE LA INVENCIÓN. DESCRIPTION OF THE INVENTION.
El objeto de la presente invención es una camisa pre-enfriadora o camisa exterior o segunda camisa para recircular el agua que posteriormente se usará para fabricar el hielo. Esta segunda camisa rodea la virola del fabricador de hielo en cuyo interior están alojados una serie de tubos dispuestos verticalmente, contando esta virola con una entrada de un gas refrigerante y una salida del mismo, disponiéndose adicionalmente una camisa pre-enfriadora, que envuelve a la primera y por cuyo interior discurre un canal de agua que presenta la entrada de agua de dicho canal en la parte inferior, mientras que la salida del agua se encuentra en la parte superior de manera que dicho canal dispuesto de manera helicoidal alrededor de la longitud sufre un enfriamiento desde su entrada hasta su salida y posterior uso como agua para congelar dentro de los conductos de la torre. The object of the present invention is a pre-chilling jacket or outer jacket or second jacket to recirculate the water that will later be used to manufacture the ice. This second sleeve surrounds the ferrule of the ice maker inside which are housed a series of vertically arranged tubes, this ferrule having an inlet of a refrigerant gas and an outlet thereof, a precooler sleeve being additionally provided, which wraps the first and through which a water channel runs which presents the water inlet of said channel in the lower part, while the water outlet is in the upper part so that said channel arranged helically around the length suffers a cooling from its entrance until its exit and later use as water to freeze inside the pipes of the tower.
Gracias a la disposición de esta segunda camisa se evita un intercambio de calor con el exterior del líquido refrigerante, y además, gracias a disponer un canal que rodea la longitud de la virola del fabricador y por cuyo interior discurre agua, se consigue una reducción en la temperatura de entrada del agua a congelar y en consecuencia un menor requerimiento energético del agua a congelar. Thanks to the arrangement of this second sleeve, an exchange of heat with the outside of the coolant is prevented, and in addition, thanks to the provision of a channel that surrounds the length of the ferrule of the manufacturer and through which water runs, a reduction in the inlet temperature of the water to be frozen and, consequently, a lower energy requirement of the water to be frozen.

EXPLANATION OF A PREFERRED EMBODIMENT
A la vista de las figuras se describe seguidamente un modo de realización preferente de la invención propuesta. En la figura 1 , puede observarse que la máquina para fabricar hielo comprende un fabricador (1) provisto de una pared exterior o camisa o virola en cuyo interior hay dispuestos una serie de tubos verticales dentro de los cuales circula el agua para su congelación. Dicha fabricador cuenta con una salida (3) de gas refrigerante, y una entrada (4) de dicho gas refrigerante de manera que congela el agua dentro de los tubos formadores verticales (2) y tras un golpe de calor se extraen como cilindros macizos el hielo formado para su posterior cortado. In view of the figures, a preferred embodiment of the proposed invention is described below. In Figure 1, it can be seen that the ice machine comprises a manufacturer (1) provided with an outer wall or sleeve or ferrule inside which are arranged a series of vertical tubes within which circulates water for freezing. Said manufacturer has an outlet (3) of refrigerant gas, and an inlet (4) of said refrigerant gas so that it freezes the water inside the vertical forming tubes (2) and after a heat stroke the solid cylinders are extracted as ice formed for later cutting.
Adicionalmente el fabricador (1) cuenta con una camisa pre-enfriadora (5) o envolvente de la camisa o virola, por cuyo interior discurre un canal (8) para recuperación del frió del gas refrigerante, presentando una entrada (6) en la parte inferior de la camisa pre- enfriadora (5) y una salida (7) en la parte superior de esta camisa pre-enfriadora (5), discurriendo el canal, en una posible forma de realización, de manera helicoidal a lo largo de la longitud de la virola, consiguiendo de esta manera una reducción de la temperatura del agua a emplear, que en una realización comprobada pasaría de una temperatura de entrada de 21°C a una temperatura de salida de 7°C. In addition, the manufacturer (1) has a pre-chill jacket (5) or jacket of the jacket or ferrule, inside which runs a channel (8) for recovery of the refrigerant gas cold, presenting an entry (6) in the part bottom of the pre-chiller sleeve (5) and an outlet (7) in the upper part of this pre-chiller sleeve (5), the channel running, in a possible embodiment, helically along the length of the ferrule, thereby achieving a reduction in the temperature of the water to be used, which in a tested embodiment would pass from an inlet temperature of 21 ° C to an outlet temperature of 7 ° C.
Gracias a la doble combinación de una segunda camisa (5) envolvente del fabricador o su virola, junto con un canal que discurre a lo largo de la longitud de la virola, se consigue un aprovechamiento energético y en consecuencia una reducción del coste del consumo energético al conseguir que la temperatura del agua de entrada se reduzca claramente. No altera la esencialidad de esta invención variaciones en materiales, forma, tamaño y disposición de los elementos componentes, descritos de manera no limitativa, bastando ésta para su reproducción por un experto. Thanks to the double combination of a second sleeve (5) enclosing the manufacturer or its ferrule, along with a channel that runs along the length of the ferrule, an energy use is achieved and consequently a reduction in the cost of energy consumption by getting the temperature of the water inlet clearly reduced. The essentiality of this invention does not alter variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, this being sufficient for its reproduction by an expert.
