The liquid separated from the Spray Nozzle creates a curtain. The curtain of liquid formed maintains this structure for a while without breaking into droplets. The impact effect of the liquid curtain is higher than the spray that splits into its droplets. Another feature of spoon spray nozzles is that it can achieve wide spray angles. This group of spray nozzles are especially preferred in food washing, conveyor cleaning, surface preparation baths before painting, engine block and part cleaning processes where the impact effect is desired.
