Water pre-cooling jacket for a vertical multitubular-type ice-making machine

Abstract

The invention relates to a water pre-cooling jacket for a vertical multitubular-type ice-making machine comprising an ice maker (1) having an outer wall or jacket or sleeve in whose interior a series of vertical tubes (2) are disposed, containing water for freezing thereof, said ice maker having a cooling gas inlet (4) and an outlet (3) of said cooling gas, the pre-cooling jacket (5) having a channel (8) for recovering the cold from the cooling gas having an inlet (6) on the lower part of the pre-cooling jacket (5) and an outlet (7) on the upper part of this jacket (5), said duct extending spirally, or with any other geometry and achieving a reduction in temperature from 21° C. at the inlet to 7° C. at the outlet.

Description

OBJECT OF THE INVENTION[0001]The object of the present invention, as established in the title, is to include an external jacket or pre-cooling jacket in the design of a vertical multitubular-type ice-making machine to recirculate the water that will subsequently be used to manufacture the ice.[0002]The present installation is characterised in that it endows ice-making machines of this type with a configuration and geometry such as to improve the energy efficiency of the installation in its entirety, taking advantage of the cold losses that these machines have on their outer surface to cool the water entering the tubes in charge of making the ice.[0003]Therefore, the present invention falls within the field of vertical multitubular-type ice-making machines.BACKGROUND OF THE INVENTION[0004]The use of ice is on the rise, particularly due to the demand for drinks by both the hospitality industry and by distribution chains.[0005]Vertical multitubular-type ice-making installations have a ...

AI Technical Summary

Benefits of technology

The patent describes a new way to cool ice-making machines that improves energy efficiency by using the cold that the machines lose on their surface. This results in a more efficient installation.

Problems solved by technology

However, the external part of the jacket or sleeve through whose interior the cooling gas flows is directly in contact with the surrounding air, which implies a heat exchange with the exterior which is not taken advantage of, said jacket or sleeve not having any insulation, thereby giving rise to energy loss and decreased performance of the machine.
