Dry-ice pellet blasting method for the pulsed cleaning of objects by means of a gas stream carrying dry-ice pellets, with dry-ice pellets being produced by compaction of CO 2 snow and subsequently being introduced into the gas stream and accelerated, and the gas stream carrying the dry-ice pellets being discharged via a blast outlet nozzle, and the object to be cleaned thus being impinged upon, the dry-ice pellets being formed from CO 2 snow in a compacting device by means of intermeshing compactor wheels having an axial through-opening in at least one compactor wheel , by outwardly protruding projections of one compactor wheel being brought into and out of engagement with compaction recesses , which are complementary thereto and open substantially radially inward into the through-openings , in the other compactor wheel when the compactor wheels roll against one another, so that as a result CO 2 snow introduced into a gap of the intermeshing compactor wheels is compacted to form dry ice and the dry ice is pressed radially inward into the relevant through-opening and is broken to form dry-ice pellets, characterized in that the gas stream is guided through the axial through-opening of at least one or preferably two intermeshing compactor wheels , specifically is introduced into the axial through-opening in the axial direction and is guided through the axial through-opening in the axial direction, so that the dry-ice pellets pressed radially inward into the relevant through-opening are directly fed to the gas stream and carried along thereby, so that the dry-ice pellets are produced only during the execution of the blasting method. with dry-ice pellets being produced by compaction of CO 2 snow and subsequently being introduced into the gas stream and accelerated, and the gas stream carrying the dry-ice pellets being discharged via a blast outlet nozzle, and the object to be cleaned thus being impinged upon, the dry-ice pellets being formed from CO 2 snow in a compacting device by means of intermeshing compactor wheels having an axial through-opening in at least one compactor wheel , by outwardly protruding projections of one compactor wheel being brought into and out of engagement with compaction recesses , which are complementary thereto and open substantially radially inward into the through-openings , in the other compactor wheel when the compactor wheels roll against one another, so that as a result CO 2 snow introduced into a gap of the intermeshing compactor wheels is compacted to form dry ice and the dry ice is pressed radially inward into the relevant through-opening and is broken to form dry-ice pellets, characterized in that the gas stream is guided through the axial through-opening of at least one or preferably two intermeshing compactor wheels , specifically is introduced into the axial through-opening in the axial direction and is guided through the axial through-opening in the axial direction, so that the dry-ice pellets pressed radially inward into the relevant through-opening are directly fed to the gas stream and carried along thereby, so that the dry-ice pellets are produced only during the execution of the blasting method. <EOS>
