Apparatus and method for producing co2 pellets from co2 snow, and cleaning appliance

A cleaning appliance for blasting surfaces to be treated with a mixed stream of a pressurized gas and CO2 pellets, wherein the cleaning appliance comprises an apparatus for producing, in particular high-strength, CO2 pellets from CO2 snow, wherein the apparatus comprises a compressing device for compressing CO2 snow to form CO2 pellets and a delivery device for delivering the CO2 pellets into a pressurized gas stream, wherein the apparatus comprises a fluid mechanical transfer device for conveying CO2 pellets from the compressing device to the delivery device and wherein the transfer device is arranged or formed between the compressing device and the delivery device.

A method for producing, in particular high-strength, CO2 pellets from CO2 snow, in particular for a cleaning appliance for blasting surfaces to be treated with a mixed stream of a pressurized gas and CO2 pellets, in which method CO2 snow is compressed to form CO2 pellets, wherein the formed CO2 pellets are fluid mechanically transferred for delivery or introduction into a pressurized gas stream.
