Abstract
A dispensing nozzle comprising an ultrasound emitter is disclosed. A wall of the ultrasound emitter defines a channel. The ultrasound emitter comprises an inlet, a top and a bottom. The bottom of the ultrasound emitter may comprise a conical outlet. The conical outlet comprises an outer diameter that decreases in size in a direction towards an outlet opening defined by the conical outlet. The channel may extend from the inlet to the conical outlet. The dispensing nozzle further comprises a tube. The tube may be configured to deliver free-flowing material to the inlet. The ultrasound emitter may be configured to deliver ultrasound waves to free-flowing material flowing through channel. The ultrasound emitter may be configured to induce cavitation in free-flowing material passing through the conical outlet. The cavitation may be sufficient to destroy microorganisms and reduce microbial contamination of the free-flowing material dispensed from the dispensing nozzle.
