I claim: 1. A foamed milk system for creating foamed milk from a source of milk, a source of air, and a source of steam, comprising: a milk inlet system for pressurizing the milk; an air inlet system for pressurizing the air; a mixing area to mix the pressurized milk, the pressurized air, and the s
I claim: 1. A foamed milk system for creating foamed milk from a source of milk, a source of air, and a source of steam, comprising: a milk inlet system for pressurizing the milk; an air inlet system for pressurizing the air; a mixing area to mix the pressurized milk, the pressurized air, and the steam; the mixing area comprising an annular region formed between an inner wall of a hollow nozzle block and a mixture nozzle positioned within the hollow nozzle block; and an expansion area to expand the mixture of the pressurized milk, the pressurized air, and the steam. 2. The foamed milk system of claim 1, wherein said milk inlet system comprises a peristaltic pump. 3. The foamed milk system of claim 2, wherein said milk inlet system comprises a disposable hose connecting the source of milk and said peristaltic pump. 4. The foamed milk system of claim 1, wherein the air inlet system comprises an air pump. 5. The foamed milk system of claim 1, further comprising a hose connector connecting said milk inlet system and said air inlet system. 6. The foamed milk system of claim 5, wherein said hose connector comprises a three-way valve. 7. The foamed milk system of claim 5, wherein said hose connector comprises a four-way valve. 8. The foam milk system of claim 5, wherein said hose connector comprises a plurality of barbed connections. 9. The foamed milk system of claim 5, wherein said milk inlet system comprises a disposable hose connecting said hose connector. 10. The foamed milk system of claim 5, wherein said air inlet system comprises a disposable hose connecting said hose connector. 11. The foamed milk system of claim 10, wherein said disposable hose comprises a microfilter positioned therein. 12. The foamed milk system of claim 10, wherein said disposable hose comprises one or more check valves positioned therein. 13. The foamed milk system of claim 5, further comprising a disposable hose connecting said hose connector and said mixing area. 14. The foamed milk system of claim 1, further comprising a steam hose connecting the source of steam and said mixing area. 15. The foamed milk system of claim 1, wherein said mixture nozzle comprises a plurality of protrusions positioned thereon. 16. The foamed milk system of claim 15, wherein said mixture nozzle comprises a plurality of orifice areas positioned about said plurality of protrusions. 17. The foamed milk system of claim 1, wherein said mixture nozzle comprises a removable nozzle. 18. The foamed milk system of claim 1, further comprising a diffuser to gather the flow of the foamed milk to be dispensed. 19. The foamed milk system of claim 18, wherein said diffuser comprises a diffuser insert and a spout. 20. The foamed milk system of claim 1, further comprising a sanitation system. 21. The foamed milk system of claim 20, wherein said sanitation system comprises a source of hot water. 22. The foamed milk system of claim 21, wherein said sanitation system comprises a sanitation valve adjacent to said source of hot water so as to provide hot water to said mixing area and said expansion area. 23. A steamed milk system for creating steamed milk from pressurized milk and steam, comprising: a mixing area to mix the pressurized milk and the steam; a pressurized milk inlet system for injecting the pressurized milk into the said mixing area; a steam inlet system for injecting the steam into said mixing area; said mixing area comprising an annular region formed between an inner wall of a hollow nozzle block and a mixture nozzle positioned within the hollow nozzle block; an expansion area to expand the pressurized milk and the steam to form a flow of steamed milk; and a diffuser to gather the flow of the steamed milk to be dispensed.
