Abstract (en)
[origin: WO2022101317A1] The aim of the invention is to improve the manageability of a cleaning device (10) for blasting surfaces to be treated with a mixed stream consisting of compressed gas and CO2 pellets, comprising a device (12) for producing CO2 pellets from liquid or gaseous CO2. This is achieved in that the device comprises a compression device (14) for compressing CO2 snow in order to form the CO2 pellets, the cleaning device (10) comprises a drive device (36) with a driveshaft for driving the compression device (14) and the driveshaft runs parallel or substantially parallel to the direction of gravity (28) when the cleaning device is used as intended.
