An output device for a milk foaming apparatus , wherein the output device comprises: an emulsifying chamber with a fluid inlet (15-1) for introducing a fluid containing milk, air and/or steam into the emulsifying chamber , wherein said fluid emulsifies in the emulsifying chamber so as to form an emulsified fluid in the form of milk foam, and an output portion with an output opening for dispensing the emulsified fluid from the emulsifying chamber , wherein said output portion comprises at least one output channel that is fluidically connected to the emulsifying chamber and the output opening such that the emulsified fluid is enabled to flow from the emulsifying chamber to the output opening through the at least one output channel , wherein a deflecting surface and/or at least one deflecting member for decelerating and swirling the fluid introduced into the emulsifying chamber is furthermore arranged in the output portion , characterized in that a sieve element arrangement with at least one sieve element is provided, wherein said sieve element comprises multiple passages and is arranged upstream of the output opening such that emulsified fluid flowing from the emulsifying chamber to the output opening has to pass through the at least one sieve element via at least one of the passages , and in that a hydraulic diameter (d h ) of the passages lies in the range between 0.1 and 1.5 mm and a length of the passages lies in the range between 0.1 and 1.5 mm, wherein the passages of the at least one sieve element are arranged in a space that extends annularly around the deflecting surface and/or the at least one deflecting member . an emulsifying chamber with a fluid inlet (15-1) for introducing a fluid containing milk, air and/or steam into the emulsifying chamber , wherein said fluid emulsifies in the emulsifying chamber so as to form an emulsified fluid in the form of milk foam, and an output portion with an output opening for dispensing the emulsified fluid from the emulsifying chamber , wherein said output portion comprises at least one output channel that is fluidically connected to the emulsifying chamber and the output opening such that the emulsified fluid is enabled to flow from the emulsifying chamber to the output opening through the at least one output channel , wherein a deflecting surface and/or at least one deflecting member for decelerating and swirling the fluid introduced into the emulsifying chamber is furthermore arranged in the output portion , characterized in that a sieve element arrangement with at least one sieve element is provided, wherein said sieve element comprises multiple passages and is arranged upstream of the output opening such that emulsified fluid flowing from the emulsifying chamber to the output opening has to pass through the at least one sieve element via at least one of the passages , and in that a hydraulic diameter (d h ) of the passages lies in the range between 0.1 and 1.5 mm and a length of the passages lies in the range between 0.1 and 1.5 mm, wherein the passages of the at least one sieve element are arranged in a space that extends annularly around the deflecting surface and/or the at least one deflecting member . <EOS>
