Abstract
A nozzle for spraying sublimable solid particles and preventing frost from forming at surfaces of the nozzle. The nozzle includes: a cleaning agent block for phase-changing a cleaning agent into a snow containing sublimable solid particles; a nozzle block for growing the cleaning agent snow through adiabatic expansion and spraying the grown cleaning agent snow onto a surface of an object; a carrier gas block for supplying a carrier gas to the nozzle block to mix with the cleaning agent snow; and a heater for heating at least a portion of the carrier gas supplied from the carrier gas supply source. Fine dry ice particles and liquid CO, passing through a solenoid valve from a COreservoir tank and a pressure drop of a flow rate regulation valve, are introduced into the spray nozzle and then mixed with the carrier gas, such as N2 or purified air, and discharged.
