CAMISA PRE-ENFRIADORA DE AGUA PARA FABRICADOR DE HIELO DEL TIPO VERTICAL-MULTITUBULARPRE-COOLING WATER SHIRT FOR VERTICAL-MULTITUBULAR TYPE ICE MANUFACTURER

OBJETO DE LA INVENCIÓNOBJECT 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 the object of the present invention, as the title of the same establishes, to incorporate in the design of ice makers of the vertical-multitubular type an outer jacket or pre-chiller 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.It characterizes the present installation, the fact to provide to the machines for ice making of this type a configuration and geometry such that it improves the energy efficiency of the whole of the installation taking advantage of the losses of cold that these machines have on their outer surface to cool the inlet 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 within the scope of machines of the vertical-multitubular type for ice making.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND 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 on the rise, especially due to the demand for beverages, having a market both in hospitality and in the distribution 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 facilities for making vertical-multitubular ice type, 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 subjected to the pipes to a heat stroke that causes the ice formed inside the tube and that has a cylinder shape 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 jacket or ferrule through which the refrigerant gas flows, is in its outer part directly in contact with the surrounding air, which means a heat exchange with the outside environment that is not used, said jacket being or ferrule without any insulation, resulting in a loss of energy and a decrease in machine performance.

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 the object of the present invention to improve the machines for making ice of this type by taking advantage of the energy loss of the refrigerant gas by being in direct contact with the outside environment, developing a jacket like the one described below and is 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 precooling jacket or outer jacket or second jacket to recirculate the water that will later be used to make the ice. This second jacket surrounds the ice maker ferrule inside which a series of vertically arranged tubes are housed, this ferrule having an inlet of a refrigerant gas and an outlet thereof, additionally providing a pre-cooling jacket, which wraps around the first and through which a water channel runs that has the water inlet of said channel in the lower part, while the water outlet is in the upper part so that said channel helically arranged around the length suffers a cooling from its entrance to its exit and later use as water to freeze inside the ducts 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 jacket, an exchange of heat with the outside of the coolant is avoided, and also, thanks to having a channel that surrounds the length of the ferrule of the manufacturer and through which water flows, a reduction in the inlet temperature of the water to be frozen and consequently a lower energy requirement of the water to be frozen.
