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.

1. A dispensing nozzle comprising: a substantially vertically oriented, elongated ultrasound emitter, the ultrasound emitter having a wall, the wall having an outside surface, an inside surface, and a thickness between the outside surface and the inside surface, the inner surface of the wall defining a channel, the ultrasound emitter having an inlet at a side of the ultrasound emitter, the wall of the ultrasound emitter having an upper portion and a lower portion, the lower portion of the wall having a conical outlet, wherein the conical outlet has an outer diameter that decreases in size in a downward direction towards an outlet opening defined by an outlet edge at a bottom of the conical outlet, wherein the thickness of the lower portion of the wall reduces at a rate that is non-exponential and in a direction towards the outlet edge, the channel extending from the inlet to the outlet edge of the conical outlet, anda tube, the tube configured to deliver free-flowing food material to the side inlet of the ultrasound emitter, the tube comprising a substantially vertical portion, a substantially horizontal portion, and an elbow between the substantially vertical portion and the substantially horizontal portion, wherein the substantially horizontal portion is attached to a horizontal surface of the side inlet at an end opposite the elbow,wherein the side inlet is placed at a position on the ultrasound emitter that corresponds to a node of ultrasound waves delivered by the ultrasound emitter, and wherein the conical outlet is placed at a position that corresponds to an anti-node of ultrasound waves delivered by the ultrasound emitter,the ultrasound emitter configured to deliver ultrasound waves to free-flowing food material flowing through the channel. 2. The dispensing nozzle of claim 1, further comprising an ultrasound transducer, the ultrasound transducer configured to generate ultrasound waves, the ultrasound transducer coupled to the ultrasound emitter. 3. The dispensing nozzle of claim 2, wherein the ultrasound transducer is selected from the group consisting of a magnetostriction-based transducer and a piezoelectric ultrasound transducer. 4. The dispensing nozzle of claim 1, wherein an opening defined by the inlet of the ultrasound emitter is substantially perpendicular to an opening defined by the conical outlet of the ultrasound emitter. 5. The dispensing nozzle of claim 1, wherein the ultrasound emitter is configured to induce cavitation in a free-flowing food material passing through the conical outlet, the cavitation sufficient to destroy microorganisms and reduce microbial contamination of the free-flowing food material dispensed from the dispensing nozzle. 6. The dispensing nozzle of claim 1, wherein the channel has a substantially uniform diameter. 7. The dispensing nozzle of claim 1 further comprising a protective collar, the protective collar defining an opening, the protective collar having a longitudinal length, the longitudinal length of the protective collar being greater than a longitudinal length of a portion of the wall that defines the channel. 8. The dispensing nozzle of claim 7, wherein the protective collar defines an opening positioned underneath and aligned with the outlet opening defined by the conical outlet of the ultrasound emitter. 9. The dispensing nozzle of claim 8, wherein the protective collar has a portion having an upper section and a lower section, the protective collar tapering from the upper section to the lower section. 10. A dispensing nozzle comprising: a substantially vertically oriented, elongated ultrasound emitter, the ultrasound emitter having a wall having an outside surface, an inside surface, and a thickness between the outside surface and the inside surface, the inner surface of the wall defining a channel, the ultrasound emitter having at least a first side inlet at a first side of the ultrasound emitter and at least a second side inlet at a second side of the ultrasound emitter, the wall of the ultrasound emitter having an upper portion and a lower portion, the lower portion of the wall having a conical outlet, wherein the conical outlet has an outer diameter that decreases in size in a downward direction towards an outlet opening defined by an outlet edge at a bottom of the conical outlet, wherein the thickness of the lower portion of the wall reduces at a rate that is non-exponential and in a direction towards the outlet edge, the channel extending from each of the at least first side inlet and the at least second side inlet to the outlet edge of the conical outlet,a first tube, the first tube configured to deliver free-flowing food material to the at least first side inlet of the ultrasound emitter, the first tube comprising a substantially vertical portion, a substantially horizontal portion, and an elbow between the substantially vertical portion and the substantially horizontal portion, wherein the substantially horizontal portion of the first tube is attached to a horizontal surface of the first side inlet at an end opposite the elbow of the first tube,a second tube, the second tube configured to deliver free-flowing food material to the at least second side inlet of the ultrasound emitter, the second tube comprising a substantially vertical portion, a substantially horizontal portion, and an elbow between the substantially vertical portion and the substantially horizontal portion of the second tube, wherein the substantially horizontal portion of the second tube is attached to a horizontal surface of the second side inlet at an end opposite the elbow of the second tube,wherein the at least first inlet and the at least second inlet are each placed at a position on the ultrasound emitter that corresponds to a node of ultrasound waves delivered by the ultrasound emitter, and wherein the conical outlet is placed at a position that corresponds to an anti-node of ultrasound waves delivered by the ultrasound emitter,the ultrasound emitter configured to deliver ultrasound waves to free-flowing food material flowing through the channel. 11. The dispensing nozzle of claim 10, further comprising an ultrasound transducer, the ultrasound transducer configured to generate ultrasound waves, the ultrasound transducer coupled to the ultrasound emitter. 12. The dispensing nozzle of claim 11, wherein the ultrasound transducer is selected from the group consisting of a magnetostriction-based transducer and a piezoelectric ultrasound transducer. 13. The dispensing nozzle of claim 10, wherein an opening defined by the at least first inlet and an opening defined by the at least second inlet of the ultrasound emitter are each substantially perpendicular to an opening defined by the conical outlet of the ultrasound emitter. 14. The dispensing nozzle of claim 10, wherein the ultrasound emitter is configured to induce cavitation in free-flowing food material passing through the conical outlet, the cavitation sufficient to destroy microorganisms and reduce microbial contamination of the free-flowing food material dispensed from the dispensing nozzle. 15. The dispensing nozzle of claim 10, wherein the channel has a substantially uniform diameter. 16. The dispensing nozzle of claim 10 further comprising a protective collar, the protective collar defining an opening, the protective collar having a longitudinal length, the longitudinal length of the protective collar being greater than a longitudinal length of a portion of the wall that defines the channel. 17.
