<p>Device for producing a stream of dry ice particles comprises a unit for super-cooling liquid carbon dioxide (3) with a compression refrigerating machine (20) for withdrawing heat from the liquid carbon dioxide by vaporizing a compressed liquefied heat transfer fluid. Preferred Features: A pressure-increasing unit (15) for compressing the liquid carbon dioxide is assigned to a removal line (6) for the carbon dioxide. A cooling device (31) for removing the compression heat fed to the pressure-increasing unit is assigned to the pressure-increasing unit.</p> |
