Beschreibung
Zusammenfassung:	The present invention relates to a device for producing high-strength CO2 pellets from CO2 snow, in particular, for a cleaning device for blasting surfaces to be treated with a mixed-flow consisting of a compressed gas and CO2 pellets, including a main compressing device for compressing CO2 snow for forming CO2 pellets, further including a pre-compressing device for pre-compressing CO2 snow produced by expanding liquid CO2, wherein the pre-compressing device is in the form of a fluid-mechanical pre-compressing device, wherein the pre-compressing device includes an expansion device for producing CO2 snow from liquid or gaseous CO2 and a pre-compression chamber for receiving and pre-compressing the produced CO2 snow and wherein the expansion device and the pre-compression chamber are connected to one another in fluidic manner.
