<p>The invention relates to a device (1) for generating dry ice snow (T), with: A rotating body (10) mounted in a housing (20) so that it can rotate around a rotational axis (R), wherein the rotating body (10) exhibits at least one expansion chamber (13) on the circumference of the rotating body (10), a feed line for introducing liquid carbon dioxide into the at least one expansion chamber (13), an inlet opening (21) of the housing (20) for introducing a gaseous mass flow (D), in particular compressed air, into the at least one expansion chamber (13), and an outlet opening (22) of the housing (20) for dispensing the dry ice snow (T) generated in the respective expansion chamber (13) from the housing (20). The invention here provides that the inlet opening (21) and outlet opening (22) are arranged in such a way that the at least one expansion chamber (13) can be simultaneously connected with the inlet opening (21) and outlet opening (22) in terms of flow by rotating the rotating body (10) around the rotational axis (R), so that at least sections of the at least one expansion chamber (13) can carry a gaseous mass flow (D) introduced through the inlet opening (21) along the rotational axis (R).</p> |
