Abstract: Disclosed is a machine for producing ice cubes, which comprises a tray specially designed for producing ice cubes, wherein an antifreeze liquid is used as a cold transmission medium, the forming tray comprising, on one side, a forming casing, and on the other side, a tray for spraying and collecting non-frozen sprayed water, the forming casing comprising a series of forming cavities aligned in rows that are each staggered with respect to the next. The machine further comprises a pair of tubes arranged at the side of the forming casing and connected to the free inside space between the forming cavities, which tubes are for pumping and returning the antifreeze liquid.

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.

Abstract: Ice-cutting machine comprising a cylindrical tank (1) on the upper portion of which two circular blades (2) are arranged, being raised at a certain height above a supporting assembly (3), which constitutes the supporting base of the cylindrical bars, provided with one rotation motor (4) and another translation motor (5) that impart a compound rotational and translational motion, wherein the supporting assembly (3) is provided with two crescent-shaped supports (3.1) that have a ramp (3.2), which prevents the ice bars from being damaged by the teeth of the blades; the blades are fixed by means of screws (2.2); the cylindrical tank (1) is provided with a register flap (6) and the rotation motor (4) is fixed on a platform (8) which in turn is fixed to the cylindrical tank (1), and the rotation motor (4) and platform assembly is covered by a casing (8).
