DEVICE FOR DRY ICE BLASTING

PROBLEM TO BE SOLVED: To provide a dry ice blasting device in which two injection nozzles are mounted at a single dry ice blasting device each capable of operating at individually setup injection pressure while one or both the two injection nozzles can be operated according to necessity.SOLUTION: The dry ice blasting device includes, as main components: tube bodies 2A which carry compressed gas flows; a single rotary feeder 6 for mixing dry ice particles into the compressed gas flows: and hoses 31, 32 that connect the rotary feeder 6 and injection nozzles 41, 42 in which valves 21B, 22B are installed in the tube bodies 2A branched at a branching tube body 2C to depressurize or shut off the compressed gas flows, respectively, and based on signals of actuators 41A, 42A and the setting of a controller 4B, blasting by means of dry ice can be performed individually at the injection nozzles 41, 42.
