Abstract (en)

[origin: WO2011029825A2] The invention relates to a method for producing solid carbon dioxide particles, wherein liquid carbon dioxide is brought into thermal contact with a coolant in a heat exchanger and is cooled to a temperature just above the solidification temperature thereof. The cooled liquid carbon dioxide is subsequently guided in a nozzle assembly cooled by contact with a coolant, in which it is cooled further by thermal contact with said nozzle assembly before it escapes from an opening of said assembly. Said thus produced cold-solidified carbon dioxide particles have a higher resistance than the conventionally produced CO2-particles.
