Abstract

An apparatus for producing CO2 particles, in particular of high strength, from CO2 snow, in particular for a cleaning appliance which sprays a surface to be treated with a mixed stream consisting of compressed gas and CO2 particles, comprising a compression device for compressing CO2 snow to form CO2 particles and a transfer device for transferring the CO2 particles into the compressed gas stream, in order to improve the apparatus in such a way that it can be operated reliably, it is proposed that the apparatus comprises a fluid-dynamic conveying device for conveying the CO2 particles from the compression device to the transfer device, and that the conveying device is arranged or configured between the compression device and the transfer device. Furthermore, an improved cleaning appliance and an improved method for producing CO2 particles from CO2 snow are proposed.
