A slush ice maker includes a fluid chiller having water circulation tubes in which water flowing therethrough is deeply cooled to about 32°F., a water conduit system coupled with the chiller and including a high pressure pump for pumping water through the tubes at a pressure of about 2 to 4 atmospheres and at a velocity in excess of 9 ft. per second to effect the formation of ice crystals in the water so as to define the slush ice. The ice and water mixture is discharged into an ice accumulation tank maintained at atmospheric pressure so that the formation of ice crystals are enhanced when the pressure of the slush ice is reduced to atmospheric at the tank.

An apparatus for making slush ice, comprising an elongated shell having closed end walls, a plurality of water circulation tubes lying parallel to the axis of said shell and extending between said end walls, pipe return bends located outwardly of said end walls and respectively interconnecting pairs

An apparatus for making slush ice, comprising an elongated shell having closed end walls, a plurality of water circulation tubes lying parallel to the axis of said shell and extending between said end walls, pipe return bends located outwardly of said end walls and respectively interconnecting pairs of said tubes to define a continuous flow path between inletting and outletting ones of said tubes, a water inlet connected to said inletting tube and a water outlet connected to said outletting tube, a slush ice accumulation tank at said fluid outlet for collecting slush ice at atmospheric pressure, refrigeration means for cooling water circulating through said tubes at approximately a water freezing temperature, and a high pressure pump in said fluid inlet for pumping water through said tubes at an elevated pressure of about 2 to 4 atmospheres and at a high velocity in excess of 9 ft. per second, whereby ice crystals are formed in the water at the elevated pressure and at the high velocity and are enhanced when the pressure of the ice crystals and water is reduced to atmospheric in said tank.
