Composite nozzle for expresso coffee making machine - has nozzle for steam fitted inside nozzle for compressed air

摘要

The nozzle is for making Cappucino coffee with an Expresso coffee machine. It has an inner pipe (4) which is connected to the steam supply. This inner pipe is surrounded by an outer pipe (6) through which compressed air is supplied. Both pipes (4, 6) terminate in converging nozzles (10, 14) with the steam nozzle (10) projecting beyond the end of the air nozzle (14). This design of nozzle prevents milk being drawn into the nozzle so that no deposits remain after use and consequently the nozzle can be easily cleaned. ADVANTAGE - Limited mfg. cost.
