Abstract (en)

[origin: EP0125964A1] 1. Process for cooling a material (3) with the aid of a liquefied gas, characterized in that it comprises the following stages : (a) bringing the liquefied gas into a nozzle (8), said liquefied gas being at a temperature below its saturation point and whereof the variation from the latter does not exceed 15 C, (b) expanding said liquefied gas in order to obtain droplets, (c) shattering these droplets by applying thereto a carrier gas, the flow rate and pressure of the cooling liquid and the carrier gas being regulated in such a way that the droplets obtained have a diameter equal to or below 40 microns and (d) spraying the droplets obtained in stage (c) onto material (3) in order to cool the latter.
